ZM120 06.100.007 Cover (ZM-120U Travel Differential)

ZM120 06.100.007 Cover (ZM-120U Travel Differential)

The ZM120 06.100.007 cover is a retaining sealing component of the ZM120 06.100.000-05 travel differential running axle, designed to secure and protect the 1-30x52-1 reinforced oil seal within the bearing assembly. It is used on self-propelled grain throwers of the ZM-120U series manufactured by us, as well as during the modernization of running systems on other grain thrower modifications when transitioning to a gearless drive layout with an independent gearmotor.

Two such covers are used in the design of the central differential-one is installed on the left side onto the ZM120 01.460.05-05 sprocket with cover, and the second on the right side onto the ZM120 06.100.004-05 cast-iron cover. The component tightly presses the oil seal into its seating socket, ensuring the leak-tightness of the differential oil drum and protecting the internal 180206 bearings from dust, dirt, and other abrasive particles.

Design Features of the ZM-120 Axle Differential Cover

The component is manufactured from high-quality cast iron with finish turning of the seating surfaces. The use of SCH 20 cast iron ensures the geometric stability of the pressing flange and resistance to corrosion in the working environment. The internal bore for the oil seal is machined with precise tolerances, guaranteeing a tight fit of the seal without deformation or misalignments of its casing.

The design of the cover ensures reliable retention and protection of the reinforced oil seal. The internal ring bore precisely fixes the 1-30x52-1 oil seal, preventing it from being pushed out under oil pressure or temperature rises inside the drum. The precisely machined pressing end face ensures uniform contact with the housing, guaranteeing the leak-tightness of the left and right half-axle bearing assemblies.

Four-point bolted fastening ensures uniform fixation along the entire perimeter-four symmetrical holes for M8x30 bolts are drilled in the cover flange. Even tightening of the four threaded connections via spring lock washers prevents spontaneous loosening due to vibration and ensures stable pressing of the sealing assembly throughout the entire service life.
