ZM120 06.120.001-05 Shaft (Left Long, ZM-120U Differential)

ZM120 06.120.001-05 Shaft (Left Long, ZM-120U Differential)

The ZM120 06.120.001-05 shaft is a solid steel shaft (left half-axle) of the ZM120 06.100.000-05 differential running axle, designed to transmit torque from the differential bevel group directly to the hub (flange) of the left drive wheel. It is utilized on self-propelled grain throwers of the ZM-120U series, as well as during the modernization of running systems on alternative grain thrower modifications when transitioning to a gearless drive layout featuring an independent gearmotor and pneumatic wheels.

The component is supplied as a standalone machined shaft (without a bevel gear, keys, bearings, or the wheel mounting flange). Purchasing an individual shaft represents a rational solution for targeted repairs of the left side when the shaft itself exhibits mechanical wear beneath the bearings or keyway damage, while associated components remain fit for continued operation.

Technical Specifications of the ZM120 06.120.001-05 Shaft

• Catalog number - ZM120 06.120.001-05 (base shaft of the "Complete Left Half-Axle Assembly" ZM120 06.120.000-05)
• Application - left side (span from the differential to the left drive wheel) of the ZM120 06.100.000-05 running axle for ZM-120U grain throwers
• Purpose: - receiving torque from the bevel gear and transmitting it to the left wheel mounting flange
• Material - calibrated structural steel featuring machined seating journals and milled keyways
• Seating parameters - solid Ø30 mm shaft for internal 180206 bearings (within the sprocket with cover), external H 026.058 bearing assemblies (11206 bearing), and the wheel hub (mounting flange)
• Keyway configuration - the inner end features a longitudinal keyway for an 8x7x25 key, while the outer end features a T-shaped connection (a longitudinal keyway for an 8x7x50 key and a transverse milled groove for the ZM120 06.100.009 retaining plate)
• Quantity per machine - 1 pc.
• Country of manufacture - Ukraine

Design Features and Operation within the Kinematic Chain

Precise machining of the steel round bar ensures strict alignment of all support journals. The shaft is machined from solid steel bar stock in compliance with specified tolerances for mounting two 180206 ball bearings inside the ZM120 01.460.05-05 sprocket with cover, and an 11206 spherical bearing within the external H 026.058 cast-iron housing.

The specialized geometry of the shaft ends ensures secure mating with power assemblies:

• The inner end of the shaft extends inside the differential oil drum, where the ZM 07.603-05 driven bevel gear (z=28, m=3.5) is mounted using an 8x7x25 key and an M8 fixing set screw.
• The outer (wheel) end of the shaft features a T-shaped keyway system, where the longitudinal keyway for an 8x7x50 key transmits torque to the ZM120 06.150.000 wheel mounting flange, and the transverse slot accommodates the hardened ZM120 06.100.009 retaining plate, which bolts to the wheel hub to block any axial shifting or slippage of the wheel off the shaft during travel across uneven surfaces.

Associated Components for Assembling the ZM-120 Rear Travel Left Span
