ZP 07.110.000 Differential Cross Spider Assembly (for ZM-120U Travel Axle)

ZP 07.110.000 Differential Cross Spider Assembly (for ZM-120U Travel Axle)

The ZP 07.110.000 differential cross spider assembly is the central planetary unit housed inside the ZM120 06.100.001 drum within the ZM120 06.100.000-05 travel differential. This unit is engineered for self-propelled grain throwers of the ZM-120U series, and is also applied during the modernization of running systems on other grain thrower modifications when transitioning to a gearless drive layout with an independent gearmotor.

The assembly is responsible for automatically redistributing torque between the left and right half-axles during grain thrower maneuvering and turning. Supplying the cross spider as a complete assembly significantly simplifies travel axle repairs, eliminating the need to separately select side gears, press-fit cermet bushings, and establish clearances in field conditions.

Design Features of the Differential Cross Spider on Pins

The unit's bevel side gears are in constant, precise mesh with the half-axle gears. Two ZM 07.605 bevel side gears with 17 teeth (module m=3.5) operate in pairs with the half-axle gears (z=28). High-precision turning and gear-cutting execution of the hardened steel side gears guarantee smooth planetary mechanism operation without binding or noise during changes in wheel angular speeds.

The side gear pins are equipped with wear-resistant cermet bushings to reduce friction. Special ZM 07.105-01 bushings (sized 25x32x20 mm) and a central ZM 07.105 bushing (sized 25x32x45 mm) are utilized for the pins. The porous structure of the cermet effectively retains liquid lubricant from the filled drum, ensuring a low friction coefficient, freedom from scuffing, and an extended service life for the plain bearings under alternating loads.

The assembly design ensures secure pin retention within the cross spider housing. The ZP 07.608 side gear pins are rigidly secured inside the body of the ZP 07.609 cross spider using two M6x15 locking screws-preventing pin displacement or loosening even during intensive towing across uneven threshing floors.

Associated Components for Differential Overhaul

During a complete overhaul or restoration of the central drum along with the ZP 07.110.000 cross spider, adjacent elements are typically inspected and replaced:

• ZM 07.603-05 bevel half-axle gears (z=28, m=3.5) - 2 pcs.
• Compensation washer set (ZP 07.401, ZS4008-01, ZS4008-02) for bevel mesh adjustment
• Complete differential housing assembly ZM120 06.100.001
• Right (ZM120 06.110.000-05 SB) and left (ZM120 06.120.000-05 SB) half-axles
• OVB 6023 (M16) drain plug for level control and oil replacement
