ZM120 01.460.05-05 Sprocket with Cover (ZM-120U Travel Differential)

ZM120 01.460.05-05 Sprocket with Cover (ZM-120U Travel Differential)

The ZM120 01.460.05-05 sprocket with cover is a monolithic combined running axle assembly featuring the ZM120 06.100.000-05 differential, which integrates the functions of a drive chain sprocket and a supporting cast-iron bearing assembly cover. It is engineered for self-propelled grain throwers of the ZM-120U series, and is also utilized during the modernization and retrofitting of running systems on alternative grain thrower series when transitioning to a gearless drive layout with an independent gearmotor.

The component mounts onto the left end of the differential oil drum and transmits torque from the gearmotor chain drive directly to the differential housing. Delivering this factory-assembled unit complete with proper sealing and a precisely bored bearing chamber enables quick replacement of a worn sprocket without the need for separate bearing selection and press-fitting in field conditions.

Design Features of the ZM-120 Differential Sprocket with Cover

The component is manufactured from durable SCH 20 cast iron, where the solid cast housing effectively dampens micro-vibrations from the chain drive, protecting bearings and oil seals from premature wear. The internal sprocket chamber is bored to precise tolerances for 180206 bearings. High machining precision of the Ø62 mm internal bore ensures a snug fit for the dual 180206 bearing package without play or misalignments. Due to strict adherence to coaxiality, the ZM120 06.120.000-05 left half-axle rotates smoothly, and the working lip of the 1-30x52-1 oil seal fits tightly against the shaft, maintaining oil drum leak-tightness.

The precisely cut chain ring ensures smooth, jerk-free drive operation. Sprocket teeth are cut on gear hobbing machines with subsequent precise pitch and profile control-ensuring ideal engagement with the drive chain, reducing noise levels during grain thrower operation, and preventing accelerated wear or chain derailment under heavy loads.
