ZM120 06.140.000 Elastic Coupling Flange (ZM-120U Travel Differential)

ZM120 06.140.000 Elastic Coupling Flange (ZM-120U Travel Differential)

The ZM120 06.140.000 elastic coupling flange is a connecting hub element of the travel axle with the ZM120 06.100.000-05 differential, designed for the rigid connection of shafts with a rubber-metal elastic coupling. The unit is utilized on self-propelled grain throwers of the ZM-120U series, as well as during the modernization and retrofitting of running systems on other grain thrower series when transitioning to a gearless drive layout with an independent gearmotor.

Within the kinematic chain, the right half-axle of the differential connects to the intermediate shaft precisely through a set of such flanges and a VAZ 2101-2202120 elastic coupling. The application of a factory flange ensures backlash-free torque transmission, compensates for minor angular and axial shaft displacements during grain thrower movement, and simplifies the installation and removal of drive elements during servicing.

Technical Specifications of the ZM120 06.140.000 Flange

• Catalog number - ZM120 06.140.000 (depending on the specific modification and position on the drive line, the designation ZM120 06.150.000 is also encountered).
• Application - ZM120 06.100.000-05 travel differential for ZM-120U grain throwers and upgraded gearmotor travel systems.
• Purpose - connecting the right half-axle and intermediate shaft with the VAZ 2101-2202120 elastic coupling.
• Material - high-strength SCH 20 cast iron (or structural steel upon request) with finish turning and milling operations.
• Seating bore - Ø30 mm for a shaft with a keyway for an 8x7x45 prismatic key (GOST 23360-78).
• Coupling fastening method - three-lobed, three-point bolted connection (for M10x40 bolts).
• Quantity per machine - 2 pcs. (one on each side of the elastic coupling).
• Country of manufacture - Ukraine.

Design Features and Engineering Advantages

The component is manufactured from high-quality metal with high-precision turning of the seating bore. The internal Ø30 mm bore is machined to precise tolerances, ensuring a tight fit of the flange onto the output end of the ZM120 06.110.000-05 half-axle and the ZM120 06.130.001 intermediate shaft. The standard keyway for an 8x7x45 key is designed for high torque and prevents flange rotation on the shaft even under shock loads during travel reversal.

The three-lobed flange features a symmetrical bolt pattern for reliable fixation of the elastic coupling. Three mounting holes are bored for M10x40 fastening bolts, exactly matching the mounting bosses of the VAZ rubber-metal coupling. This design guarantees uniform clamping and eliminates misalignments when tightening fasteners, allowing the elastic coupling to effectively dampen travel drive vibrations and protect shafts from premature wear.

The unit is designed with standardization in mind for various drive modifications. Depending on the specific production year or running axle configuration, two variants of this flange (ZM120 06.140.000 and ZM120 06.150.000) are utilized on grain throwers, fulfilling an identical role as connecting elements of the elastic coupling for a standard 8x7x45 key and a 30 mm shaft. The precise geometry of factory manufacturing ensures complete interchangeability and quick installation of parts in place of worn-out flanges.

Associated Components for Assembly
