Background technique
Coupling is widely used in mechanical transmission fields.Generally speaking, be applied to the transmission with moment of torsion of rotatablely moving between axle and axle.To the coupling performance demands; Except that can reliable delivery motion and the moment of torsion; Also require to have to alleviate and impact, reduce vibrations, reduce the effect of noise, and have certain angle, axially, compensating action radially, to reduce the influence of alignment error to coupling work.Its structure generally is made up of three parts, that is: the link that is connected with driving shaft, the link that is connected with driven shaft and the elastomer between two links.Using quincunx very widely elastomer coupling is exactly typical case's representative wherein.
Along with the development of industrial technology, different industries has proposed some different requirement to coupling product at present.For example at construction machinery industry, coupling generally is used for connecting between internal-combustion engine and the oil hydraulic pump, and the characteristics of application are: driving shaft is the Flywheel disc of motor normally; Transmitting torque is bigger; Load variations is big, and vibration and impact are strong, requires axial dimension compact.And because construction machinery industry, equipment generally is not in the fixed location when using, and it is not too convenient to maintain, so require non-maintaining as far as possible.
In this case, common coupling can't satisfy usage requirement.For example the slenderness ratio of quincunx elastomer coupling is generally between 1.15 to 1.7.Its axial dimension is excessive, makes under this occasion, to use.Other ask for something under this occasion has also caused general common coupling to meet the demands.
Summary of the invention
The purpose of the utility model is the characteristics of using to coupling in the construction machinery industry, and a kind of coupling that solves the existing technology problem is provided, and is applied to connecting between internal-combustion engine and the oil hydraulic pump.
The utility model is achieved in that the coupling that a kind of side drum type tooth is connected; Comprise link that is connected with driving shaft and the link that is connected with driven shaft; It is characterized in that: the said link that is connected with driving shaft is a Flywheel disc; The said link that is connected with driven shaft is for unshakable in one's determination, and said Flywheel disc is that side drum type tooth is connected with Placement unshakable in one's determination, and Flywheel disc is connected fixing with the Flywheel disc of driving shaft motor by connecting bolt; Said endoporus unshakable in one's determination is connected through the spline form with the driven shaft oil hydraulic pump, and spline is given oil hydraulic pump with power transmission.Described iron core is radially offered the wide groove of 2～3mm through shaft axis, and the both sides of groove are provided with tapped hole, through lock bolt splined shaft in the endoporus unshakable in one's determination is clamped, and the coupling iron core is reliably located with hydraulic pump shaft.
In the utility model,,, be able to shorten axial dimension so greatly simplify the structure because Flywheel disc has elastomeric effect and the effect that is connected with driving shaft in the general coupling simultaneously.
In the utility model, the length of said iron core is at 40mm～80mm, and said Flywheel disc diameter is at 100mm～200mm, and the slenderness ratio of coupling is 0.2～0.8.
The beneficial effect of the utility model is: it is steady to have power transmission, and transmitting torque is big, absorbed oscillation and impact effectively, and oil resistant, high temperature resistant, simple in structure, easy for installation, the characteristics of Maintenance free.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Among the figure: 1, connecting bolt; 2, Flywheel disc; 3, iron core; 4, lock bolt.
Embodiment
According to attaching Fig. 1 and 2, the utility model is the coupling that a kind of side drum type tooth is connected, and is made up of connecting bolt 1, Flywheel disc 2, iron core 3 and lock bolt 4.Flywheel disc 2 is that side drum type tooth is connected with the Placement of iron core 3.
During use, Flywheel disc 2 is connected with the engine flywheel dish by connecting bolt 1, and Flywheel disc meshes transmission of power on unshakable in one's determination 3 through the cydariform external tooth of internal tooth with iron core 3.Unshakable in one's determination 3 endoporus generally is connected through the spline form with hydraulic pump shaft, through spline power is passed to oil hydraulic pump.
This coupler structure is simple, reliable operation, and rate of fault is low.The coupling Flywheel disc uses reinforced glass fiber nylon material, and heat resistanceheat resistant stability has high mechanical properties and thermostability to+120 ℃.Length of installation is short, assemble easyly, turns round to rigidity highly, and running does not have and resonates, and can effectively compensate alignment error.
Form multiple tooth, little tooth that engagement between iron core and Flywheel disc is adopted; The outer flank of tooth unshakable in one's determination adopts the drum type tooth; This kind Scheme Selection can improve unshakable in one's determination and intermeshing reliability of Flywheel disc and adaptability; Reduction is to the requirement of coupling mounting process, improve coupling radially, angle and axial centering capacity.In addition,, make the transmission of torsion compare uniform and stable, improved the absorbing buffer capacity, reduced operating noise because the number of teeth of engagement is more.
The utility model is compared with elastic coupling flexible coupling commonly used, in power transmission process, turns round to rigidity higherly, is difficult for taking place phenomenon of torsional vibration.
The means of fixation on hydraulic pump shaft unshakable in one's determination is a kind of unique simple and high-efficient structural type in the utility model.On iron core, radially cut the groove that 2～3mm is wide, clamp with lock bolt then through axial location, the resiliently deformable that under the effect of clamping force, produces unshakable in one's determination, thereby to splined shaft generation clamping force.The coupling iron core is reliably located with pump shaft.Because lock bolt directly do not contact with splined shaft, the damage that lock bolt possibly cause the splined shaft surface in the time of can having avoided coupling mechanism force excessive effectively.In case unclamp the keyway lock bolt, then along with the loosening of material deformation clamping force, coupling is unshakable in one's determination to be disengaged with pump shaft.The structure of this form can effectively be adjusted the gap error of hole between centers, reduces and turns round shake, reduces the wearing and tearing of pump shaft, avoids too early maintenance and replacing, alleviates the weight of equipment, is suitable for quick assembling, reduces noise.
According to attaching Fig. 1 and 2, because its design feature, it is very little that axial dimension can be done, and length unshakable in one's determination is generally between 40 to 80mm.And the Flywheel disc diameter can change between 100 to 200mm, and corresponding slenderness ratio is between 0.2 to 0.8.If special requirement can also be accomplished lowlyer, be particularly suitable for the occasion that requires axial dimension little.
The characteristics of the utility model: axial dimension is little, and transmitting torque is big, has stronger absorbed oscillation and impact capacity, and has certain angle, axial, radial compensation effect, and is lower to installation and maintenance maintenance conditional request.
