Abstract
A differential gear mechanism for driving a detaching roller of a comber includes two driving systems. One of the driving systems converts constant-speed rotational motion into variable-speed rotational motion through a crank mechanism and a quadric crank mechanism. The variable-speed rotational motion is transmitted to the input shaft of the differential mechanism. The other driving system converts constant-speed rotational motion into swing motion by a crank mechanism, converts the swing motion into reciprocating motion by way of connecting rods and linkage, and transmits the reciprocating motion to a planet pinion of the differential gear mechanism. The feed motion curve of the detaching roller produced by the differential gear mechanism is an ideal curve similar to that obtained by an ideally designed cam comber.
