Abstract
The utility model discloses an overrunning clutch, and particularly relates to an internal star wheel type overrunning clutch for a loader, i.e., a clutch which is applied to automobiles, engineering construction locomotives and the like for transferring power torque. The overrunning clutch comprises an intermediate input shaft, wherein an outer ring gear is sleeved outside the intermediate input shaft; an inner ring cam is arranged between the outer ring gear and the intermediate input shaft; an inner ring rollway is formed between the inner ring cam and the outer ring gear; the edge of the inner ring cam is provided with uniformly distributed outer teeth; the inner ring cam is rotatablely connected with the outer ring gear through a roller; the roller is arranged in the outer teeth; an inner hole is formed in the outer teeth; a spring seat is arranged in the inner hole; a spring is arranged in the spring seat and is pressed against the roller; and the inner hole is an oblique hole. The internal star wheel type overrunning clutch for the loader has the advantages of rational structure, convenience in use and capabilities of prolonging the service life and reducing the use cost and the maintenance cost.
Description
Technical field
The utility model is a kind of free wheel device, and particularly a kind of loader is applied to the clutch of automobile, engineering construction locomotive even flowing moment of torsion with star-wheel formula free wheel device.
Background technique
The main structure of employed driving type free wheel device is made of input block and outer ring gear in the prior art, and input assembly comprises the inner race on intermediate input axle, interior ring cam and the interior ring cam.Be inserted in isolating ring on the interior ring cam external diameter, roller is loaded into isolating ring and the spring of packing in the position of gland regulation, and spring promotes isolating ring work.Because isolating ring is thin-walled parts, manufacturability is relatively poor, yielding, minute requirement such as the roller slot on the isolating frame is high, the end face upper spring seat requires high to roller slot center superposition degree, machining accuracy is difficult to guarantee, therefore so that roller synchronously pretension on raceway, roller unbalance stress between inside and outside raceway is asynchronous, roller wearing and tearing are inhomogeneous during work, thereby cause roller surface on the star-wheel successively to be worn and torn and aggravate the damage of isolating frame, finally cause the inefficacy of two axle assemblies.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and compact structure reduces the operation and maintenance cost, the loader that increases the service life star-wheel formula free wheel device.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of loader star-wheel formula free wheel device, comprise the intermediate input axle, described intermediate input outer shaft sleeve has outer ring gear, described outer ring gear and intermediate input between centers are provided with interior ring cam, form inner race between described interior ring cam and outer ring gear, the edge of described interior ring cam is provided with equally distributed external tooth, described interior ring cam rotates by roller with outer ring gear and is connected, described roller is located in the external tooth, be provided with endoporus in the described external tooth, be provided with spring seat in the described endoporus, be provided with spring in the described spring seat, described spring is slope hole with roller phase crimping, described endoporus.
Import respectively input assembly and outer ring gear at exterior power, and do to mesh counterclockwise to turn round, higher than outer ring gear rotating speed at input assembly, roller is in raceway face idle running and surmounts state, the power of outer ring gear can't import into, power directly imports into and exports from input assembly, the input assembly rotating speed is lower than the outer ring gear rotating speed, roller is in the raceway face frictional rotation and wedging, input assembly and outer ring gear are rotated together, and two power are inputted together from input assembly and outer ring gear, common output, output torque strengthens, to satisfy all kinds of job requirements.
As preferably, described outer ring gear is located by left bearing and right bearing mutually with the intermediate input between centers, locate mutually by bearing spacer between described left bearing and right bearing, described left bearing is located mutually by back-up ring, described interior ring cam keeps off mutually with the intermediate input axle by left back-up ring and connecing, and described interior ring cam keeps off mutually with outer ring gear by right back-up ring and connecing.
As preferably, described interior ring cam and intermediate input axle fix by bolt.
Therefore, a kind of loader that the utility model provides is with star-wheel formula free wheel device, and is rational in infrastructure, easy to use, increases the service life, and reduces the operation and maintenance cost.
