Abstract
The utility model provides a chain which comprises a pin shaft, a shaft sleeve and a roller sleeve. A wear-resisting layer is arranged on the surface of the pin shaft, the pin shaft is sleeved with the shaft sleeve, the shaft sleeve is sleeved with the roller sleeve, ball rolling tracks are arranged on the outer surface of the shaft sleeve and the inner surface of the roller sleeve, balls are arranged between the shaft sleeve and the roller sleeve, the two sides of the shaft sleeve are tightly abutted against an inner chain plate, the outer side of the inner chain plate is tightly abutted against an outer chain plate, and the end portion of the pin shaft is a quadrangle rivet point. According to the chain, abrasion of the pin shaft and the abrasion of the shaft sleeve are reduced, the service life of the chain is prolonged, the cost is saved, production efficiency is improved, the safety and reliability operation of a corresponding transmission part is ensured, the direct connecting fastness of the pin shaft and a chain piece is increased through the quadrangle rivet point, and the chain enables the chain piece and the pin shaft to be connected in a more-tightness mode.
Description
Technical field
The utility model belongs to the mechanical transmission component technical field, relates to a kind of chain.
Background technique
Chain is mainly as transmission part.The chain of conventional design is to be combined by outer plate, bearing pin, inner plate and roller at present, and wherein roller housing is located on the bearing pin.In the course of the work, transmission part and roller contact transmitted load, thus this moment, roller tended to rotate and the bearing pin friction, and both all can wear and tear, and have reduced the working life of chain.
The model utility content
For addressing the above problem, the utility model provides a kind of chain.
Concrete solution is: a kind of chain, comprise that the surface is provided with the bearing pin of wearing layer, is set in the axle sleeve on the bearing pin and is set in roller shell on the axle sleeve, the outer surface of described axle sleeve and the internal surface of roller shell are provided with the ball rolling rail, be provided with ball between described axle sleeve and the roller shell, described axle sleeve both sides are near inner plate, the inner plate outside is near outer plate, and described end part of pin shaft is four jiaos of snap riveting heads.
The outer surface of axle sleeve and the internal surface of roller shell all pass through surface treatment, and described surface treatment can be nitriding, carburizing or shot blast.Process through laser transformation hardening on the ball surface.
Further, described four jiaos of snap riveting heads are via rolling riveter roll riveting moulding.
The utility model has reduced the wearing and tearing of bearing pin and axle sleeve, increased the working life of chain, saved cost, improved manufacturing efficiency, guaranteed the safe and reliable operation of corresponding transmission part, chain has increased directly degree of being connected firmly of bearing pin and chain sheet by four jiaos of snap riveting heads, and it is tightr that the chain sheet is connected with bearing pin.
