Abstract
An integral chain wheel for heavy duty machinery, the wheel teeth for driving are uniformly arranged on external circumference side of the chain wheel; a tread is arranged on one side of the wheel tooth; the treads on the adjacent wheel teeth are positioned on different sides of the wheel tooth; and the tooth surface of the wheel tooth of the chain wheel is in the shape of circular arc surface. The utility model has simple structure, good casting technique, small contact stress between the wheel tooth of the chain wheel and the pin bush, long service life, reliable contact between the wheel tooth of the chain wheel and the pin bush and good driving performance, and is applicable for heavy duty field and crawling crane etc. heavy duty machinery operating condition, the pin bush and the wheel tooth of the chain wheel are not easily abraded; and the pin bush and the wheel tooth of the chain wheel are not easily derailed and slipped.
Description
Technical field
The utility model relates to a kind of sprocket wheel, and especially heavy-duty machinery such as a kind of crawler crane is used the integral type sprocket wheel.
Background technology
Heavy-duty machineries such as present domestic crawler crane use the structure of sprocket wheel all to be gear ring type, gear ring type sprocket wheel handling ease, and precision prescribed is low, if castability better needn't be processed and can be used; But sprocket teeth is that two roundlet arcs contact with guide, and contact stress is big, incompatible heavily loaded occasion; Heavy-duty machinery operating modes such as incompatibility crawler crane, guide and sprocket teeth are easy to wear, and service life is lower; It is unreliable that sprocket teeth contacts with guide, is prone to derailing, skids, and rideability is bad.
Summary of the invention
The purpose of the utility model provides a kind of heavy-duty machinery and uses the integral type sprocket wheel, solve sprocket teeth that heavy-duty machinery such as crawler crane exists with the gear ring type sprocket wheel and heavy-duty machinery operating modes such as big, the incompatible heavily loaded occasion of guide contact stress, incompatibility crawler crane, guide is easy to wear with sprocket teeth, service life is lower, sprocket teeth contacts with guide unreliable, easy derail skid, problem that rideability is bad.
The purpose of the utility model realizes as follows: be uniformly distributed with on the all-in-one-piece sprocket wheel outer circumference surface to drive and use the gear teeth, a side of the gear teeth has tread, and the tread of adjacent teeth is in the not homonymy of the gear teeth, promptly tread in the two sides of sprocket wheel cross-distribution.Be with projection on the caterpillar block, the gear teeth directly mesh with the caterpillar block projection, and the caterpillar block load bearing face itself becomes the roller track of wheel such as caterpillar wheel.
The gear teeth flank of tooth of sprocket wheel is an arc surface.
The utility model is an integral type, and casting manufacturability is good, and is simple in structure, in light weight, and sprocket teeth is that the plane contacts with great circle arc with the caterpillar block projection, and contact stress is little, can be applicable to heavily loaded occasion, adapts to heavy-duty machinery operating modes such as crawler crane; The chain wheel tread contacts with the caterpillar block load bearing face, and a part of moment of torsion is just transmitted by the chain wheel tread, and very big tensile force is also born by the chain wheel tread in the crawler belt simultaneously, has reduced the stressed of sprocket teeth, has also reduced wearing and tearing, has improved the life-span of sprocket wheel; Sprocket teeth contacts reliably with the caterpillar block projection, is difficult for derailing, is difficult for skidding, and rideability is good.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
With reference to accompanying drawing, be uniformly distributed with driving on the all-in-one-piece sprocket wheel outer circumference surface with the gear teeth 2, a side of the gear teeth 2 has tread 1, and the tread 1 of adjacent teeth 2 is in the not homonymy of the gear teeth 2, and the gear teeth 2 flank of tooth of sprocket wheel are arc surface.Band projection 3 on the supporting with it caterpillar block, the gear teeth 2 directly mesh with projection 3, and caterpillar block load bearing face 4 itself becomes the roller track of wheel such as caterpillar wheel.
