Complete ZM120 06.100.001 Housing Assembly (ZM-120U Travel Differential)

Complete ZM120 06.100.001 Housing Assembly (ZM-120U Travel Differential)

The ZM120 06.100.001 housing assembly serves as the foundation of the load-bearing structure for the central drum within the ZM120 06.100.000-05 travel differential. This unit is engineered for installation on ZM-120U series grain throwers, and is also applied during the modernization of running systems on alternative grain thrower series when transitioning to a gearless layout featuring an independent travel gearmotor.

The housing functions as a closed oil bath and a heavy-duty power drum housing the differential planetary mechanism. When assembled with the ZM120 06.100.004-05 side cover and the ZM120 01.460.05-05 drive sprocket with cover, the component forms a sealed reservoir for continuous liquid lubrication of the bevel gears and planet gears. The housing receives torque from the gearmotor chain drive and transmits it via internal brackets to the ZP 07.110 cross, ensuring smooth and stable operation of the independent wheel drive.

Design Features and Engineering Advantages

The welded assembly thick-walled metal structure guarantees high rigidity and durability of the drum under prolonged dynamic loads. The housing is assembled from a steel cylindrical shell and internal structural elements within a spatial welding jig. Following welding, the housing undergoes finish turning and boring operations on CNC machine tools, ensuring precise coaxiality of seating surfaces and uniform contact with the side covers.

The internal support brackets for the differential cross are responsible for backlash-free torque transmission to the planetary gear. Steel bracket plates featuring precise mounting bolt holes are welded inside the drum. They form a rigid power cradle for installing the ZP 07.110 cross-a solution that restrains the cross against angular displacement, eliminating misalignments of the ZM 07.605 bevel planet gears and preventing premature uneven wear.

Smooth external geometry and reliable oil bath sealing are designed for long-lasting operation in dusty environments. The threaded hole for the M16 drain plug (OVB 6023) is machined directly into the thick cylinder wall without external protruding bosses, preserving compact housing dimensions and eliminating protruding parts that could snag during rotation. The end faces of the cylinder are bored to accommodate sealing elements and mate with the ZM120 06.100.004-05 cover and the ZM120 01.460.05-05 sprocket with cover, forming a closed enclosure.

Components and Associated Parts of the Housing Assembly

During disassembly or major overhaul of the ZM-120 travel differential, renewing the ZM120 06.100.001 housing alone should be combined with inspecting internal and adjacent planetary drum elements. At Zavod Moroza, you can order the housing separately as well as all associated parts:

• ZM120 06.100.004-05 complete cover assembly
• ZM120 01.460.05-05 sprocket with cover
• ZP 07.110.000 SB complete differential cross assembly including bevel planet gears
• M16 drain plug (OVB 6023)
• 180206 ball bearings (GOST 8882-75) - 4 pcs., installed in the side covers
• 1-30x52-1 reinforced oil seals (GOST 8752-79) for half-axle output sealing
• M8x30 mounting bolts, M8 nuts, and spring lock washers
