Abstract
The utility model relates to an inner ring cam pack especially relates to an inner ring cam pack for freewheel clutch. Including the cam body, the centre of the cam body be equipped with a pilot hole, the cam body in be equipped with evenly distributed's locating hole, the edge of the cam body be equipped with continuous distribution's roller plane end, roller plane end in be equipped with the roller and keep off and connect the end, the roller keep off connecing and be equipped with the spring assembly hole in the end. A inner ring cam pack for freewheel clutch compact structure has improved freewheel clutch's bearing capacity, has prolonged freewheel clutch's life -span.
Description
Technical field
The utility model relates to a kind of inner ring cam pack, particularly relates to a kind of inner ring cam pack for free wheel device.
Background technique
Free wheel device is the parts of very core in loading machine gearbox, is also one of critical component being easy in loading machine gearbox break down.Loader free wheel device, comprise intermediate input shaftgear, outer ring gear, inner ring cam, right baffle-plate, right baffle plate, roller, bolt and Returnning spring etc., right baffle-plate and right baffle plate are positioned at the both sides of roller, carry out spacing to roller, bolt is connected into one right baffle-plate, right baffle plate, inner ring cam and intermediate input shaftgear, roller wedging or unclamp between the roller working surface of inner ring cam and the roller working surface of outer ring gear, make free wheel device realize combining or being separated, Returnning spring ensures that roller is in wedging position at any time.Bearing capacity is low, and the plane of its main deficiency to be the roller working surface of inner ring cam be high H, contact strength is low.Therefore, the major failure of existing free wheel device shows: the roller working surface of inner ring cam is gone out pit by roller rolling press, then makes roller wear, causes free wheel device to lose efficacy, and cannot normally work again.
Model utility content
The utility model mainly solves the deficiencies in the prior art, provides a kind of compact structure, the inner ring cam pack for free wheel device that reliability is high, usability is excellent.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of inner ring cam pack for free wheel device, comprise cam body, the centre of described cam body is provided with axle pilot hole, the positioning hole be evenly distributed is provided with in described cam body, the edge of described cam body is provided with the roller planar ends of continuous distributed, be provided with roller gear in described roller planar ends and connect end, described roller gear connects in end and is provided with spring pilot hole;
The outer wall of described cam body is provided with assembling position, and be provided with left side seal groove in described assembling position, the right side wall of described cam body is provided with right seal groove;
The angle of described roller planar ends and spring pilot hole centre bit is 30 degree-32 and spends, and it is 90 degree that described roller gear connects end with the angle of spring pilot hole centre bit.
Equally distributed positioning hole distributes ringwise.
As preferably, described roller planar ends and the quantity of positioning hole are respectively 20.
Therefore, the inner ring cam pack for free wheel device of the present utility model, compact structure, improves the bearing capacity of free wheel device, extends the life-span of free wheel device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model.
Embodiment
