Abstract

The invention discloses a chain and inner chain pieces thereof. Each inner chain piece and one opposite chain piece can jointly define a clamping space, each inner chain piece comprises two assembledconnection parts arranged at an interval along a longitudinal center line, and a connection part connected with the assembled connection parts, each assembled connection part is proved with an assembled connection hole, the connection part is provided with a groove which is sunk in the direction away from the clamping space and is provided with two parallel spaced groove sides, the chain comprisesthe multiple inner chain pieces, multiple outer chain pieces and multiple chain shafts in series connection with the inner chain pieces and the outer chain pieces and each provided with a center axis, an axis distance is achieved between two adjacent center axes, and the ratio of the axis distance to the total width of the chain is 2.39+ / -0.12. The chain can be more suitable for being used in thefield with the higher variable segment number and meanwhile, the speed changing smoothness is improved.

Description

technical field [0001] The invention relates to a chain, in particular to a chain suitable for use in the transmission field, and an inner chain piece of the chain. Background technique [0002] The chain composed of the inner chain piece, the outer chain piece, the chain shaft and the chain roller and other parts often cooperates with the sprocket for power transmission. When the chain is used on a bicycle with a speed change function, because the chain must be To switch between several sprockets with different diameters, it is necessary to provide a structure on the chain that can improve the speed change function. [0003] Among them, the Taiwan area has announced the No. I500555 invention patent to disclose an inner chain ring piece for a bicycle chain. The inner chain ring piece has two end portions and a connecting portion connecting the end portions. In the connecting portion Towards the inner side of the other opposite link piece there is a recess, the recess has tw...
