Abstract

The utility model relates to a diaphragm-typed ratchet overdriving clutch, which is mainly composed of an inner ring, an outer ring, a ratchet ring, diaphragm grooves, an inner ring diaphragm, a ratchet wheel diaphragm and a reset spring, wherein, the outer ring and the ratchet wheel ring are support be a bearing; the inner side of the ratchet wheel ring and the outer side of the inner ring are provided with diaphragm grooves; inner ring diaphragms are arranged in the diaphragm groove; the reset spring is arranged on the outer ring; the outer ring is connected with the ratchet wheel diaphragm to form the reset spring of the outer ring diaphragm; the inner side of the outer ring is provided with a diaphragm groove; telescopic diaphragms are arranged in the diaphragm groove to form a diaphragm ratchet claw; the diaphragm ratchet claw is matched with the ratchet wheel ring to form a one-way overdriving clutch. The utility model solves the puzzles of instant and synchronous stress of the ratchet claw of a ratchet clutch. More diaphragm ratchet claws can be arranged on the outer ring. The utility model can realize the transportation with large torque and large power. The service life of the utility model can be prolonged under serious work situation.

Description

A kind of diaphragm type ratchet free wheel device

The utility model relates to a kind of diaphragm type ratchet free wheel device, is mainly used in the transmission mechanical motion.

At present, normally used ratchet type overrunning clutch mainly is made of outer shroud and ratchet ring, though have reliable operation, advantage of simple structure, but this common ratchet exists that unbalance stress is difficult accomplishes something because of number of pawls reaches less aspect high-power, and problem such as working life is short.

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of high-power, can bear high moment of torsion, small volume and long-life diaphragm type ratchet free wheel device, and keep that existing ratchet type overrunning clutch manufacturing is simple, the advantage of reliable operation.

The purpose of this utility model is achieved in that diaphragm type ratchet free wheel device mainly is made up of interior ring, outer shroud, ratchet ring, diaphragm groove, interior ring diaphragm, ratchet diaphragm and Returnning spring, between outer shroud and ratchet ring by bearings, there is the diaphragm groove in the inboard and interior ring of the ratchet ring outside, ring diaphragm in being provided with in it, promptly interior ring is that elasticity is connected with ratchet ring; Outer shroud is provided with Returnning spring, and links to each other with the ratchet diaphragm and to constitute the outer shroud diaphragm return spring; There is the diaphragm groove outer shroud inboard, is provided with telescopic diaphragm in it, constitutes the diaphragm ratchet, cooperates with ratchet ring to form mono-directional overrun clutch.

The utlity model has following advantage: because the elastic reaction of diaphragm, solved the instantaneous stressed difficult problem synchronously of ratchet of the pawl clutch of many ratchets, in ring be connected with the elasticity of ratchet and further alleviated instantaneous high moment of torsion hitting in the click, and, the volume of diaphragm is little and thin, more diaphragm ratchet can be set on outer shroud, realize the powerful transmission of high pulling torque with this.The Returnning spring of outer shroud diaphragm makes the diaphragm ratchet to wearing and tearing auto-compensation be arranged, thereby makes the utility model that very long operating life be arranged under bad working environments.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model structural representation.

Among the figure: encircle diaphragm, 5-ratchet diaphragm, 6-Returnning spring, 7-diaphragm groove in the 1-in ring, 2-outer shroud, 3-ratchet ring, the 4-.

The utility model mainly is made up of interior ring, outer shroud, ratchet ring, diaphragm groove, interior ring diaphragm, ratchet diaphragm and Returnning spring, between outer shroud 2 and the ratchet ring 3 by bearings, ratchet ring is inboard to have diaphragm groove 7 with interior ring 1 outside, ring diaphragm 4 in being provided with in it, promptly interior ring is that elasticity is connected with ratchet ring; Outer shroud is provided with Returnning spring 6, and links to each other with ratchet diaphragm 5 and to constitute the outer shroud diaphragm return spring; There are a plurality of diaphragm grooves 7 the outer shroud inboard, is provided with telescopic diaphragm in it, constitutes a plurality of diaphragm ratchets (at least 10), cooperates with ratchet ring to form mono-directional overrun clutch.

Claims
