Abstract

The present invention is gear run stepless speed changer, it is made up of active gear ring (1), driven shaft (2), one-directional rotation gear (3), (4), (5), non-return pellet (6) and connecting rod (7), and variable speed is completed by the relative position for changing active gear ring (1) and driven shaft (2).

Description

Gear run stepless speed changer

Technical field

The present invention relates to a kind of actuating unit, more particularly to a kind of gear-driven stepless speed change device.

Technical background

Up to the present, all gear-shift mechanisms are all step change transmissions.The present invention provides a kind of technology, gear drive variable speed is become a reality, and model machine is made and produces a desired effect.Gear run stepless speed changer can meet the conversion from zero-speed to arbitrary speed, and be with load speed change.So clutch is not needed also without with fluid torque-converter.If it is greatly improved its mobility and flexibility for warship, submarine, battlebus, helicopter.Driving moment can be joined directly together with engine for diesel locomotive to advance, eliminate needs to change into electric energy from mechanical energy originally, returns again to the process of mechanical energy.

The content of the invention

The gear run stepless speed changer of the present invention is made up of two parts, (one) variable speed source, (two) separating variables device.

Brief description of the drawings

Figure of description, Fig. 1 are the position views of each component before the speed change of variable speed source；Fig. 2 is the position view of each component after the speed change of variable speed source；Fig. 3 is the schematic diagram of separating variables device.

Two-part operation principle is introduced respectively now：

(1) variable speed source

Variable speed source active gear ring (1), driven shaft (2), one-directional rotation gear (3), (4), (5), non-return pellet (6) and connecting rod (7) as shown in figure 1, be made up of.

When the axle center of driven shaft (2) overlaps with the center of circle of active gear ring (1), when active gear ring (1) turns clockwise, one-directional rotation gear (3), (4), (5) can not be rolled by non-return pellet (6) is stuck, driven shaft (2) is promoted to be rotated with the logical speed of active gear ring (1) by connecting rod (7), this is the situation before speed change.

When needing speed change, make driven shaft (2) amesiality, the center of circle of active gear ring (1) is left, as shown in Figure 2, now each module position in variable speed source changes, one-directional rotation gear (5) is still stuck, but diminish with driven shaft (2) distance, active gear ring (1) still rotates in tempo, because the arm of force diminishes, the angular speed of driven shaft (2) becomes big rotating speed and accelerated, and speed change is completed.

Accelerated due to driven shaft (2) rotating speed and become big with one-way transmission gear (4) distance, one-directional rotation gear (4) is pulled by connecting rod (7), its linear velocity is more than the linear velocity of active gear ring (1), then along the inner edge preceding and then roll counter-clockwise clockwise of active gear ring (1).And one-directional rotation gear (3) is then in from one-directional rotation gear (4) transition into two kinds of working conditions of one-directional rotation gear (5)

(2) separating variables device

Only variable speed source is not all right, because its slewing range is too small, and is not since 0, therefore does not have practical value.The delta separation of speed change must be out amplified, practical technology could be turned into.

Separating variables device is as shown in Figure 3, it forms a differential mechanism by bevel gear (8), (9), (10), (11), gear (12), and gear (13) is engaged with gear (12) and is connected with dotted box (14).Dotted box (14) is expressed as variable speed source.

When identical and rotating ratio is 1: 2 to gear (12) with bevel gear (8) steering, turn no matter how fast gear, bevel gear (10) transfixion all the time, when making variable speed source produce increment, bevel gear (10) starts to rotate, and increment is bigger, and rotating speed is faster, and separating variables are come out by this device can, the variable separated is amplified by certain gear combination again, it is possible to reach converted from zero-turn speed to predetermined speed.Therefore, gear run stepless speed changer, clutch is not needed at work also without fluid torque-converter.

Embodiment

By using above-mentioned principle and using required various assemblies, so that it may put into practice this technology.
