Abstract

The invention relates to a precise transmission chain. The precise transmission chain comprises an inner link and an outer link; the outer link comprises two outer link pieces, two lateral ends of the outer link pieces are provided with press-fitting holes A, the inner link comprises two inner link pieces, and two lateral ends of the inner link pieces are provided with press-fitting holes B; the positions, corresponding to the press-fitting holes B, of the two inner link pieces are provided with annular cushion blocks; an arc-shaped cavity corresponding to the annular shapes of the cushion blocks are formed between the inner link pieces and the outer link pieces, the direction of an arc opening faces towards the longitudinal middle portions of the inner link pieces or the outer link pieces, and the arc-shaped cavity is internally provided with an arc-shaped elastic piece to achieve the support of the inner link pieces and the outer link pieces. By means of spring pieces which are arranged on the edges of the link pieces, the deflection degree of the chain is lowered, and therefore the transmission precision of the chain is improved.

Description

technical field [0001] The invention relates to a precision transmission chain, which belongs to the field of transmission mechanisms of precision equipment. Background technique [0002] In the transmission of precision equipment, precision-machined gears are generally used for transmission, and for long-distance precision transmission, screws are generally used for transmission. Under the circumstances, it is easy to wear and affect the accuracy. If the belt transmission is used, it is easy to change the tension of the belt due to the change of the environment, causing the pulley to slip to a certain extent, or because of the local difference of the belt tension, which affects Out of synchronization to the rotation speed of the pulley, thus affecting the precision of the transmission; [0003] Sprocket transmission takes advantage of the chain's low pull-up resistance and low environmental impact, and is often used as a transmission with high load-bearing capacity.
