Along with the increase of a large amount of railway train overhaul quantities, the railway train overhaul is increasingly developed towards the direction of mechanization and automation, the train wheel pair and the bogie inevitably flow from one overhaul station to another overhaul station in the overhaul process, the direction change requirement exists in the flow process, and the turntable is produced at the same time.

The turntable is driven by a motor reduction gearbox, at present, the power transmission mode is friction transmission, a friction wheel is installed on the reduction gearbox, and the friction wheel presses the outer edge of the turntable to drive the turntable to rotate. The transmission mode is easy to lose and rotate, and simultaneously has large transverse pressure, impacts the whole turntable and is rarely applied; secondly, the transmission mode has high manufacturing cost, and simultaneously has high requirement on the manufacturing precision of the turntable body, and is rarely applied; at present, chain drive is commonly used. The chain transmission has the advantages of simple design, standard parts (chain and chain wheel) supply, quick installation and low manufacturing cost. However, this solution also has obvious drawbacks: firstly, the outer edge of the turntable must be bent flatly, if the chain is embedded in the turntable, the friction between the chain and the chain wheel can be increased, the side surfaces of the chain wheel and the chain are excessively abraded, the damage failure is accelerated, and the manufacturing method is not easy to realize; secondly, the chain is easy to elongate after long-term use, and the length is not easy to adjust because the chain is arranged in the outer edge of the turntable, so that the similar effect of enlarging the pitch is caused, and the unstable rotation is formed; and the outer diameter of the outer edge of the turntable is not easy to match with the length of the chain, so that the abrasion of the chain wheel and the chain is aggravated, and the phenomenon of unstable rotation is aggravated.
