Bidirectional output unidirectional clutch mechanism

Abstract

The invention discloses a bidirectional output unidirectional clutch mechanism. The external periphery of a spline cam is respectively provided with a group of cam surfaces and convex columns uniformly, wherein the cam surfaces are circular and smooth with a lifting property, and each cam surface is distributed on the external periphery of the spline cam in the same rotation direction; a retaineris respectively uniformly provided with corresponding roller column installation gaps and radial compressed spring installation gaps; each roller column installation gap is internally provided with aroller column and a radial compressed spring; the radial compressed springs can enable the retainer to push the roller columns to the lifting direction of the cam surfaces; and each end surface of each gear is provided with a clamp bench, a spline housing spine set mechanism is fixedly sleeved on a transmission shaft at the outer side of the clamp bench, and the spline housing spine set in the spline housing spine set mechanism is clamped with the clamp benches of the gears. According to the invention, the function of the bidirectional output unidirectional clutch mechanism provided by the invention can be preferably realized through the gears and the spline housing spine set mechanism.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to a one-way clutch mechanism capable of realizing bidirectional output. Background technique [0002] In the existing overrunning clutch mechanism, an important part is a spline cam one-way device with a spline groove, because the one-way device can only rotate in one direction and lock in the other direction. When the power output part of the clutch (inner ring or outer ring) rotates faster than the power source (outer ring or inner ring), the clutch is in a disengaged state. Based on this, the overrunning clutch function of the overrunning clutch mechanism is realized. Due to the current one-way The device is mainly a spline cam type overrunning clutch, the patent number is ZL03233130.4, the name is "speed change gear device with cam type overrunning characteristics" and the patent number is ZL201010539253.8, the name is "single two-way clutch mechanis...

Problems solved by technology

When the power output part of the clutch (inner ring or outer ring) rotates faster than the power source (outer ring or inner ring), the clutch is in a disengaged state. Based on this, the overrunning clutch function of the overrunning clutch mechanism is realized. Due to the current one-way The device is mainly a spline cam type overrunning clutch, the patent number is ZL03233130.4, the name is "speed change gear device with cam type overrunning characteristics" and the patent number is ZL201010539253.8, the name is "single two-way clutch mechanism" clutch, it Including the gear, a spline cam is installed at the center of the gear. The circumference of the spline cam is evenly distributed with a plurality of sections of smooth curved surfaces with lifting characteristics. Cage, rollers are installed in the evenly divided gap of the cage, and each roller corresponds to a smooth curved surface of the spline cam with lifting characteristics; The elastic mechanism that squeezes the rollers to the direction of the spline cam lift, and the elastic mechanism is a compression spring, has the following disadvantages: first, in the case of a one-way device, the power can only be output in one direction, Drive the shaft to rotate in one direction; Second, the processing of this structure is complicated, especially for the processing of the cage. The installation position of the groove compression spring and the installation steps of the spline cam need to be processed on the plane in the cage, so the processing Difficult, high cost, difficult to mass produce

Third, the card platform of the past single- and two-way clutch mechanism is located on the end face of the cam, and the cam is looped on the shaft, so the one-way device can only work in one direction, one-way disengagement or two-way disengagement, can not Realize two-way work, one-way disengagement
