Chain sheet of chain

Abstract

A chain-sheet of chain can be outer chain-sheet, inner chain-sheet and joint chain-sheet according to the installing position, comprising a body and a first raised wing, wherein the body is at interval provided with a first side and a second side of the body, and two outer ends at interval side to side that connect the outer side edge, the first raised wing projects from one outer end with a first side of the first raised wing. The chain-sheet of the invention and another chain-sheet of the chain are assembled to make the first side of the raised wing is more closed to the other chain-sheet than the first side of the body, to reduce the gap between the chain-sheets and reduce the oscillating space while the chain-sheets are vibrated with advantages that it can increase the using safety and reduce the colliding force between the chain-sheets and the colliding noise or the like.

Description

technical field [0001] The invention relates to a chain piece, in particular to a chain piece which can be an outer chain piece, an inner chain piece or a joint chain piece according to different installation positions. Background technique [0002] Referring to Fig. 1, a general chain usually includes several series connection units 7, and a joint group 8 that connects two adjacent series connection units 7 in series, wherein each series connection unit 7 includes two inner and outer spacers Inner chain pieces 71, a bushing 70 connecting the inner chain pieces 71, two outer chain pieces 72 arranged outside the inner chain pieces 71, a chain roller 73 arranged between the inner chain pieces 71, And a chain shaft 74 that passes through the bushing 70 and is assembled with the outer chain piece 72. The joint group 8 generally includes two branch shafts 81, and two pieces of function are similar to the outer chain piece 72, but they have the function of snapping the The joint ...

Problems solved by technology

[0003] During assembly, the fastening portion 811 of the connecting shaft 81 must first extend into the large diameter portion of the fastening hole 822, and protrude from one of the outer surfaces 823 of the chain piece 82, then move to the small diameter portion so that the neck portion 813 stretches into the small diameter portion, and then Then make the fastening part 811 sit on the concave ring 814 of the small diameter part toward the direction of the inner chain piece 71. In this way, after the chain assembly is completed, there must be a gap between the inner chain piece 71 and the adjacent joint chain piece 82. There is a gap d1, so the relative movement between the connecting shaft 81 and the joint chain piece 82 is easy to occur. When subjected to an external force toward the hole 821, the connecting shaft 81 will move toward the hole 821 as shown by the arrow and fall off, so the use of this chain will have safety concerns

[0004] Similarly, in order for these elements to rotate smoothly after assembly, there will also be a gap between the inner chain piece 71 and the adjacent outer chain piece 72 after the assembly is completed, and the gap between the inner and outer chain pieces 71, 72, It is easy to shift left and right of each series connection unit 7 of the chain, because the gap between the inner chain piece 71 and the outer chain piece 72 on the series connection unit 7 is relatively large, therefore, in the process of each series connection unit 7 left and right displacement There will be a lot of collision and collision noise in the
