Abstract

The utility model provides a power transmission chain with arc structure, the chain comprises a plurality of chain links, each chain link includes outside chain piece, side chain piece in the, connecting portion, characterized by, outside chain piece, interior side chain piece is an arc bent plate chain piece. The utility model discloses a chain chain link outside chain piece, interior side chain piece adopt the arc bent plate, can be better with the match of chain dish, so more even at conveying power in -process distributing of stress through cooperation between them, can improve the efficiency of power transmission, reduce the chain deformation and damage who leads to the fact in response to the power inequality.

Description

A kind of power transmission chains bar with arcuate structure

Technical field

This utility model relates to chain, particularly relates to a kind of power transmission chains bar with arcuate structure.

Background technology

Chain is very common in daily life, it it is a kind of the most commonly used power transfer devices, what wherein use chain was known the most is bicycle, bicycle is the articles for daily use indispensable in people's daily life, the kind of bicycle also gets more and more, and is widely used in the fields such as amusement, motion, traffic, contest.

For bicycle chain, conventional chains is fabricated to a succession of inner link replaced and outer link. Each outer link is made up of relative and spaced apart a pair plate, and plate is hinged to a pair plate constituting inner link by this at the respective inner face place of they ends. The gap that inner link limits is less than the gap limited by outer link, but still is large enough to hold the sprocket wheel of corresponding bicycle or the tooth of crown gear. The plate constituting inner link keeps spaced apart by pin, and these pins are formed adjacent with the side of the sprocket wheel of bicycle or the tooth of crown gear during operation.

Links is crossed the riveted joint assembling realization of articulating pin and is formed continuously chain, and this pin includes the head with the diameter bigger than the diameter in the hole of chain link. Once this pin is fully inserted in chain link, the head of this pin is formed adjacent in the outside at the first hole place Yu the first plate of outer link. Selling the part relative with head, namely distal portion is riveted, and namely stands permanent plastic deformation, obtains opposition head by this. The diameter of opposition head is more than the diameter in the second hole presented on the second plate of outer link. In this way, articulating pin is locked in its end, it is prevented that depart from from chain link. Proper implements generally by means of the thrust device equipped with piercer and piercer is performed manually by riveted joint, and this piercer can be at least partially inserted in the distal portion of pin.

Each outer link is made up of relative and spaced apart a pair plate, and equally, inner link is also made up of relative and spaced apart a pair plate, generally, composition outer link conventional on market and the plate of inner link are straight plates, and the length of straight plate is less, to meet the needs that chain coordinates with chain drum.

Owing to chain drum is circular, and form the side chain sheet of chain link plate, interior side chain sheet is straight plate chain sheet, so be there is the problem of Stress non-homogeneity in transmitting dynamic process by both cooperations, this is the main cause causing the straight plate of chain and chain joints pin deformed damaged.

For this, this utility model provides a kind of power transmission chains bar with arcuate structure, to solve above-mentioned technical problem.

Utility model content

The purpose of this utility model is in that to provide a kind of power transmission chains bar with arcuate structure, it is intended to solve owing to chain drum is circular, and the plate forming chain link plate is straight plate, so the problem that there is Stress non-homogeneity in transmitting dynamic process by both cooperations.

The technical scheme in the invention for solving the technical problem is, a kind of power transmission chains bar with arcuate structure, and chain is made up of multiple chain links, each chain link includes outside chain sheet, interior side chain sheet, connecting portion, it is characterized in that, described outside chain sheet, interior side chain sheet is arc bent plate chain sheet.

The beneficial effects of the utility model are, chain link plate outside chain sheet of the present utility model, interior side chain sheet adopts arc bent plate, can better with chain drum matching, so it is more uniform by both cooperations stress distribution in transmitting dynamic process, the efficiency that power transmits can be improved, reduce the chain deformed damaged that stress inequality causes.

Accompanying drawing explanation

Fig. 1 forms the straight plate chain sheet schematic diagram of common chain link plate,

Fig. 2 is the bent plate chain sheet schematic diagram of the composition chain link plate that this utility model provides.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.

As shown in Figure 1 and Figure 2, in Fig. 1, form the straight plate chain sheet of common chain link plate, owing to chain drum is circular, and the plate forming chain link plate is straight plate chain sheet, so be there is the problem of Stress non-homogeneity in transmitting dynamic process by both cooperations, this is the main cause causing the straight plate chain sheet of chain and chain joints pin deformed damaged.

In Fig. 2, the bent plate chain sheet of the composition chain link plate that this utility model provides, owing to bent plate has arcuate structure, so chain of the present utility model can better with chain drum matching, so it is more uniform by both cooperations stress distribution in transmitting dynamic process, the efficiency that power transmits can be improved, reduce the chain deformed damaged that stress inequality causes.

The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.

Claims

1. having a power transmission chains bar for arcuate structure, chain is made up of multiple chain links, and each chain link includes outside chain sheet, interior side chain sheet, connecting portion, it is characterized in that, described outside chain sheet, and interior side chain sheet is arc bent plate chain sheet.
