Use and Adjustment of Drum Gear Coupling

　　Drum gear couplings are mainly used to connect the transmission shafts of various mechanisms. Due to different mechanical equipment, the functions of various couplings are also slightly different. For example, the coupling on a forklift is used to transmit the transmission between the transmission and the drive axle. Power between time. Due to the short longitudinal dimension of the drive train, forklifts under 3t generally adopt a rigid connection structure, that is, bolts are used to connect the engine, clutch, transmission, coupling housing, and drive axle, that is, from the engine to the drive axle is a rigid whole. The middle part of the rigid whole adopts a gear coupling. For forklifts above 5t, universal joints are generally used due to the longer longitudinal dimension of the transmission system.The power is transmitted to the drive axle of the forklift via the coupling.

　　The drum gear coupling is composed of two coupling discs, which are connected by their inner and outer teeth.The coupling disc with internal and external teeth is connected with the transmission and the drive axle through splines or keys.

　　1) If the spline teeth on the gear are damaged and the fit clearance is greater than 0.4mm, they should be replaced.

　　2) When the keyway on the gear is damaged, the keyway can be enlarged and replaced.Or insert another keyway at 60° from the original keyway.

　　3) When adjusting the gear coupling, the coaxiality of the two shafts should not be greater than 0.4mm.
