Tile-pin chain and machining method thereof

Abstract

The invention discloses a tile-pin chain. The tile-pin chain comprises an inner chain plate, an outer chain plate and a roller barrel, wherein a side face of one end of the inner chain plate is fixedly connected with a pin shaft; the other side face of the end of the inner chain plate is fixedly connected with a second interference inserting part; a side face of the other end of the inner chain plate is provided with a through hole; an outer side of one end of the through hole is fixedly connected with a wear-resistant ring; conical wear-resistant chamfered parts are arranged inside two ends of the roller shaft; side faces of two ends of the outer chain plate are provided with inserting holes; one end of the pin shaft is provided with a first interference inserting part; the pin shaft is rotationally sleeved with the roller barrel; and one end of the pin shaft passes through the through hole and is inserted into the inserting holes in the outer chain plate. Through the direct sleeve fit of the roller barrel and the pin shaft with a gap of less than 0.02mm, the tile-pin chain is tension-resistant and wear-resistant, and can be better matched with a chain wheel. Through the adoptionof the tile-pin chain, abnormal sound caused by tensioning of the chain of a motorcycle is lowered, and the chain regulating frequency is lowered.

Description

technical field [0001] The invention belongs to the technical field of tile chains, in particular to a tile chain, and in particular to a processing method for the tile chain. Background technique [0002] Chains are generally metal links or rings, mostly used for mechanical transmission. The chain can be divided into short-pitch precision roller chain, short-pitch precision roller chain, curved plate roller chain for heavy-duty transmission, cement machinery chain, leaf chain. According to different purposes and functions, the chain is divided into four types: transmission chain, conveyor chain, traction chain and special special chain. Transmission chains are mainly used for power transmission chains; conveyor chains are mainly used for transporting materials; traction chains are mainly used for pulling and lifting chains; special special chains are mainly used for special mechanical devices, Chains with special functions and structures. [0003] A sprocket is a wheel w...

AI Technical Summary

Problems solved by technology

Existing motorcycle chains, the chain rollers use a shaft, a small tube and a large tube; the gap between the tubes is relatively large, not tensile, not wear-resistant, easy to elongate, basically every 2000 to 3000 kilometers The chain must be adjusted once, otherwise it will not be able to cooperate well with the sprocket; and after the chain is pulled, it needs to be replaced with a new chain; the traditional chain has a high frequency of chain adjustment, which is troublesome and expensive
