Embodiment Construction

[0009] The shaft 01 and the outer retaining ring 06 are connected by the buffer block 05, the shaft 01 and the gas (liquid) cylinder are connected by the square key 09, the gas (liquid) enters the cylinder through the interface 10, and the roller cage 04 holds each roller 07 Keep it in the wedge-shaped area formed by the outer retaining ring 06 and the shaft 01, and stick to the inclined surface in the direction in which the extension spring 11 is preloaded. That is, in the tensioning direction of the extension spring 11, when the shaft 01 is active, the clutch can realize combination and overrun; when the shaft 08 is active, the combination and overrun in the opposite direction can be realized. When the clutch needs to change direction, control the air (hydraulic) action to push the piston 03, press and drive the roller cage 04 to overcome the pretension of the tension spring, so that the roller is close to the other slope of the outer retaining ring to realize the clutch func...

Abstract

An active part and a passive part of a clutch can be exchanged by gas (liquid) control, and can be combined and overrun in both clockwise and counter-clockwise directions. Two shafts are connected by rollers, an outer retainer ring and a bumping block, and the inner cavity of the outer retainer ring is a plurality of wedge areas which are formed by a plurality of bilateral symmetrical inclines; aroller retainer is under the effect of the counterclockwise pre-tightening force of a tension spring, and the rollers cling to the corresponding inclines. When the direction needs to be changed, the retainer is pushed and driven by controlling gas (liquid) action so as to overcome the pretension of the tension spring and change the direction of the clutch. The clutch can be widely used in the field of mechanical transmission, and can be adapted to the requirements of more complicated working conditions in use.

Description

technical field [0001] Roller type overrunning clutches are widely used in the field of mechanical transmission (such as machine tools, automobiles, aircraft, general machinery, mining machinery, lifting and transportation machinery), and are a type of clutch that changes with the relative speed of the active part and the driven part or the direction of rotation. A clutch that engages or disengages automatically. Background technique [0002] The roller type overrunning clutch is composed of outer ring, inner ring, rollers, dials, etc. A wedge-shaped gap is formed between the inner and outer rings to clamp or loosen the rollers. When the speed of the active part is higher than that of the passive part, the rollers are clamped. , the clutch is combined; when the speed of the active part is lower than that of the passive part, the clutch overruns. But the active and passive parts cannot be converted into each other. Contents of the invention [0003] The active and passive...
