Stitching type jaw single and bidirectional over running clutch

Abstract

The present invention discloses a press-fitting type jaw overrunning clutch, which can be used as a single or double direction overrunning clutch or a single and double direction controllable glider, and has the characteristics of huge transmissible torque, high rotating speed, no collision, small volume, large impact resistance, simplicity and reliability, and long service life. The present invention is characterized in that the press-fitting type jaw overrunning clutch is provided with a blocking embedding mechanism preventing two embedding mechanisms of a force transmission embedding mechanism and a separation embedding mechanism from being embedded under the overrunning separating condition, the mechanism on the axial direction is positioned in the two mechanisms, and the mechanism on the radial direction is positioned in the two mechanisms, between the two mechanisms or outside the two mechanisms; a lift angle of both sides blocking the working surface is formed to enough ensure the friction self-locking collided on the both sides and the stability of the blocking operating condition, in order that the lift angle has the capabilities that the adaptive axle base is changed and the abrasion is automatically compensated; no collision characteristic of the overrunning operating condition of the two embedding mechanisms is maintained for a long time, and the separating block process and the embedding return process of the embedding mechanism are absolutely reliable. In addition, the direction control mechanism and the condition control mechanism are simple and reliable, the clutch manufacture is relatively easy, the assembly is simple, and the interchangeability of an old part and a new part is strong.

Description

technical field [0001] The invention relates to a clutch device in the field of mechanical transmission, in particular but not only to a jaw clutch with a rotation overrunning function. technical background [0002] The existing overrunning clutches are all evolved from the pawl-ratchet mechanism, and there are two types: embedded and friction. In the three application fields of indexing, overrunning and backstop, the friction type is most suitable for the indexing field because of its precise positioning, and the embedded type is most suitable for overrunning and backstop, which have relatively loose requirements on the slip angle but Areas that require relatively high torque transmission capacity. However, due to the embedded, especially the collision and collision noise of the dog-type overrunning clutch when it overruns, this type of clutch has hardly been used substantially, resulting in a huge transferable torque and no slippage after engagement. play.

The Chinese patents whose application numbers are 02102352.2, 99248119.8 and 99239680.8 have announced the technical solutions of two types of jaw type overrunning clutches, but due to collision or torque, they still do not correspond to most or all of the pressure on the force transmission tooth surface Tooth impact phenomenon, the three patents still have the problem of collision or insufficient torque transmission
