Description

HYDRO MOTOR

Technical Field

The present disclosure relates to a hydro motor (hydraulic motor) operating at high torque and high speed using hydraulic fluid energy developed for use in the heavy industry, automotive industry, arms industry, construction machinery, ship industry, agricultural industry, and similar areas.

The present disclosure relates in particular to a hydro motor, which can operate with high turning moment and achieve high speed by changing the flow rate, where no energy loss occurs due to rotation of the gear shaft around its axis and rotation of the thread without contacting any secondary parts, whose shaft and gear are made up of one part and whose body can be designed according to this structure.

Prior Art

A hydraulic motor is a mechanical actuator that converts hydraulic pressure and flow into torque and angular displacement. A hydraulic motor is the rotary equivalent of a hydraulic cylinder as a linear actuator. In the hydraulic system, the hydraulic motors used to convert the hydraulic energy, which is defined as the energy of the pressurized fluids, into a circular motion, and large turning moments are obtained by using the high-pressure fluids. With hydro motors, it is possible to produce large moments using a small volume. Hydraulic motors are used in the construction machines, machine tools and similar areas where strong circular motion is required. The variable speed adjustment can be performed with hydraulic motors. The speed can be increased and reduced while the movement continues, and the direction of rotation can be changed. In terms of working principle, hydraulic motors operate with a system which is the opposite of hydraulic pumps. Unlike hydraulic pumps, fluid enters to hydraulic motors as pressurized. The pressurized fluid converts hydraulic energy into circular motion through the systems. In hydraulic pumps, the gears are turned by an electric motor to form hydraulic energy, while in the motors the pressure generated by the pump is converted to mechanical energy. When the fluid enters the hydraulic motors at high pressure, it turns the gear pair as it passes through threads of the gearwheel and converts the hydraulic energy into circular energy. Since one of the gears is connected to the motor shaft, any element mounted on it can be rotated. The number of revolution of hydraulic motors depend on the amount of fluid entering the motor. The more fluid that enters the hydraulic motor, the greater number of revolution of the motor. Direction valves are used to enable hydraulic motors to rotate in the opposite direction. In hydraulic motors, which can be used everywhere, especially in construction machines, unlimited speed adjustment can be carried out between certain values without stopping the operation. In addition, in hydraulic motors, the direction of rotation can be changed while the motor's operation continues. The most important features of hydraulic motors are that they have the ability to slow down by reducing fluid flow, brake ability and that they can be operated by connecting to any type of machines.

Today, hydraulic motors are divided into 3 classes as gear type motor, piston motor, and crawler. The fluid entering at high pressure converts hydraulic energy into circular mechanical energy with the effect of pressurized rotation as it passes through pistons, crawlers or gears connected to the shaft. Hydro motors are classified as motors capable of operating with low turning moment at high speed (up to n = 500 to 10000 rpm) and motors with high turning moment at low speed (up to n = 0 to 500 rpm). Hydraulic motors that operate with gearwheels are based on the principle of rotating a shaft that runs depending on the gearwheels by creating a certain torque of the fluid that enters between the threads of the gearwheels. Piston motors are divided into two as radial and axial piston motors. In radial piston motors, pistons do not operate in parallel axes. In crawler type hydraulic motors, the rotation of the motor shaft is provided by differential pressure. A reaction force to blades against the motor, and this force, which is tangential to the rotor, causes the motor shaft to rotate. If the fluid is directed from the motor body to the motor, the rotation of the shaft is on clockwise when viewed from the shaft end. When the oil source is directed to the cap port, the rotation is on counterclockwise when viewed from the shaft end. The direction of fluid flow is thus changing. This changing is usually carried out by an appropriate direction control valve. The difficulty to achieve high speed and high turning moment with hydro motors is one of the most important factors limiting their using. On the other hand, since mentioned pistons, crawlers and gears are in contact with two or more parts, heat arises due to friction and energy loss occurs. Another disadvantage is that the size of the hydro motors used in present is large and there is an inability to go beyond the standard design.

In order to increase the efficiency of hydro motors, many studies have been carried out today and new products have been developed. One of these studies is the invention documented in the patent application no TR2014/14509 that titled "Multi- Coat Axis + Helical Wheel Combined Hydraulic Motor Technique." By means of the invention, the multi-axis axial hydraulic motor is assembled by positioning the unit hydro motors on top of each other and forming a monolithic body and monolithic axis, assembling the body by chassis and bearing the axle into it, and connecting the multiple layers to a single hydraulic flow channel; multi-layer helical impeller, monolithic wheel-wing hydraulic pressure turbine, impeller main-wing assembly, and the negative factor position that reacts to it, 180 degree rotation and positioning of monolithic wheel-additional wing assembly and small surface reaction breaker set assembly which will produce positive power at the same level. The two multi-layered hydraulic systems formed by narrowing the reaction area are combined on a single frame to form a multi-layered annular axis hydraulic motor and the multi-layered helical impeller monolithic-wing hydraulic pressure turbine combined multi-layered axis + helical impeller combined hydraulic motor.

Another study is the invention of a useful model with no. TR2001/01632 titled "Hydraulic Motor - Pump". It is a hydraulic motor that converts hydraulic pressure in a circular motion or a pump to transfer hydraulics, water and the flow of such substances in a pressurized manner. In a circular cavity having a cylindrical rotor in the center, for moving a part (pallet) that covers the section area in the vertical direction to the center by fluid pressure to fix all surfaces differ from the pallet and for retaining the pressure to be closed on each side are essential. The pallet must return to the closed pressure cell for it complete the circular motion and become continuous. The invention provided pallet, which can be at least two, three or four pieces, pass from the closed floor to the pressure cell by hiding it in the rotor, and in this process, the opposite pallet would take the pressure and take the rotation task.

As a result, the need for a hydro motor (hydraulic motor) operating at high torque and high speed that resolves the disadvantages in the present technique and the absence of an existing solution necessitated an improvement in the relevant technical field.

In this detailed description, the high torque and high speed hydro motor (10) of the present invention utilizing the hydraulic fluid energy which is developed for use in the heavy industry, automotive industry, arms industry, construction machinery, ship industry, agricultural industry and similar fields, is described only as an example for better understanding of the subject and with no restrictive effect.

The hydro motor (10) shown in Figure-1 is designed not only to operate with a high turning moment but also to achieve high speed by changing the flow rate. Unlike the crawler, piston and gear hydro motors used in the current technique, the spur gear shaft (12) comprised by the hydro motor (10) of the invention is in one piece and is driven by pressurized hydraulic fluid about its own axis without thread contacting any secondary piece. Due to the rotation of said gear shaft (12) without contacting to any other part of the thread, heat formation and energy loss caused by friction were prevented and the technical characteristics of the hydraulic fluid were preserved. On the other hand, by combining the gear and shaft that are separate in the current technique into a single structure with the gear shaft (12) in the hydro motor (10), it is possible to design the hydro motor (10) in smaller and various sizes. Depending on the design of the said hydro motor (10), the fluid is compressed in the direction of flow at takeoff and the gear shaft (12) is forced to spin with high turning moment, the gear shaft (12), which starts to rotation, is accelerated by increasing the flow rate.

All elements in the hydro motor (10) shown in Figure-2 are positioned within the outer body (1 1 ). The said outer body (10) ensures that all parts of the hydro motor (10) are held together while at the same time protecting against external factors. The gear shaft (12), front spacer bushing (13), and rear spacer bushing (15) are positioned inside the said outer body (1 1 ). The said gear shaft (12) allows hydraulic fluid energy to be converted into circular mechanical energy by the effect of its straight thread. The said front spacer bushing (13) prevents the forward flow of hydraulic fluid and keeps the gear shaft (12) in the slot where it is positioned. The said rear spacer bushing (15) prevents the flow of hydraulic fluid backward and allows the gear shaft (12) to stay in the slot where it is positioned. Both surfaces of the said outer body (10) are covered by the front cover (14) and the rear cover (16). The said front cover (14) prevents going out the parts of the hydro motor (10) to forward and fixes them in itself. In addition, by means of the said front cover (14), the hydro motor (10) can be fixed by being connected to another structure from the front. The said rear cover (16) prevents going out the parts of the hydro motor (10) to backward and secures them in itself.

The hydro motor (10) shown in Figure-3 has three different features as of right rotation, left rotation, braking. In said hydro motor (10), the fluid entering from the right inlet point (17) for right rotation exits the continuous outlet point (19), while the left inlet point (18) is closed during this operation. Likewise, the fluid entering from the left inlet point (18) for left rotation exits the continuous outlet point (19), while the right inlet point (17) is closed during this operation. The said hydro motor (10) may be braked by connecting a circular motion control receiver. The fluid entering from the said right inlet point (17) and left inlet point (18) continuously exits from the outlet point (19) and creates a braking effect on the gear shaft (12). The inside of the outer body (1 1 ), which is the most important part of the said hydro motor (10), is specially designed in a circular manner and the gear shaft (12), due to this special design, operates in a circular motion with hydraulic fluid energy. The axial tread thickness of the gear shaft (12) and the inner specially designed area of the outer body (1 1 ) have the same thickness. The front spacer bushing (13) and rear spacer bushing (15) blocked the flow of the fluid passing through the gear shaft (12) in this area. The said gear shaft (12), exports the turning moment inlet and outlet or braking effect it receives from its gear, through its own circular axis. There are holes whose the fluid coming to the gear shaft (12) on mentioned rear spacer bushing (15). The said rear spacer bushing (15) is located outside, inside the outer body (1 1 ) and the rear cover (16). The said front spacer bushing (13) is located outside, inside the outer body (1 1 ) and the front cover (14). The four bolts at the corners are tightened to the front cover (14), passing through the rear cover (16) and the outer body (1 1 ). After this tightening operation, the rear cover (16) presses the rear spacer bushing (15) and the front cover (14) to the front spacer bushing (13) and accordingly, the assembly of the hydro motor (10) is completed. The hydraulic hose is connected to the sleeves that are connected to the sleeve connection holes on said rear cover (16) and the fluid is supplied to and exits to the hydro motor (10).
