ZM120 06.150.000 Mounting Flange (Wheel Hub) for ZM-120U

ZM120 06.150.000 Mounting Flange (Wheel Hub) for ZM-120U

The ZM120 06.150.000 mounting flange (wheel hub) is a steel wheel hub for the drive axle featuring the ZM120 06.100.000-05 differential, designed for secure fastening of pneumatic wheels onto the grain thrower drive shafts. It is utilized on self-propelled grain throwers of the ZM-120U series, as well as during the modernization of running systems on other grain thrower series when transitioning to pneumatic wheels (smooth ride) and a gearless drive layout with an independent gearmotor.

Two identical hubs (mounting flanges) are installed in the construction of a single running axle-one component on the outer end of the ZM120 06.120.001-05 left shaft and the ZM120 06.130.001 right shaft. The component serves as the connecting link between the solid smooth Ø30 mm shaft and the stamped pneumatic wheel rim.

Design Features and Advantages of Pneumatic Travel

The use of ZAZ-1102 pneumatic wheels provides a smooth ride and improves overall protection of the entire structure. Utilizing standardized automotive rims and pneumatic tires from the "Tavria" guarantees superior cushioning of the grain thrower when moving across uneven threshing floor surfaces. The pneumatic wheel effectively dampens vibrations and jolts when overcoming passages or technological thresholds, reducing shock loads on the frame, bearing assemblies, and differential components.

The precise 4x98 mm coordinate bolt pattern simplifies wheel selection and replacement. Four mounting holes conforming to the ZAZ-1102 standard are machined with high precision on the steel disc of the mounting flange (hub)-allowing common and affordable automotive rims to be easily installed without additional adapters or welding work.

T-shaped fastening on the shaft reliably blocks axial displacement of the wheel. Torque is transmitted from the shaft to the hub via an 8x7x50 mm key, and to prevent the wheel from sliding off the shaft during maneuvering, a hardened ZM120 06.100.009 retaining plate is bolted to the end face of the hub sleeve using two M8x20 bolts, engaging with the transverse groove of the shaft.
