• Specification

• Functions

1.Torque Transfer: The gear ring meshes with a smaller pinion gear connected to the hydraulic motor. As the pinion rotates, its teeth engage with the gear ring’s teeth, converting the motor’s high-speed, low-torque rotation into low-speed, high-torque motion—necessary for moving heavy loads (e.g., excavator tracks digging into soil, wheel loaders carrying aggregates).

Load Distribution: Its large diameter and multiple teeth spread operational stress evenly across the toothed surface, preventing premature wear even under extreme loads (e.g., lifting 10+ ton materials).

Stability: When mounted to the track hub or wheel, it ensures consistent rotation alignment, avoiding "wobbling" or uneven movement that could damage the final drive or cause safety hazards on job sites.
