21 Ton Road Roller Axle
1. The main reducer using Gleason bevel gear is high transmission efficiency and low noise.
2. NGW type planetary gear transmission structure is reasonable and compact.
3. Steel casting axle housing is large loading and rigid. Available in a variety of connection sizes.
4. Service brake equipped with disc-caliper-type brake guarantees large brake torque and reliability.
5. Parking brake equipped with drum-brake guarantees brake safety and reliable.
6.Suitable for 19 - 23 ton road rollers
Introduction:
21 ton road roller axle is designed for 21-ton vibratory road rollers, employing a two-stage reduction gear transmission structure. The axle housing is constructed from cast steel material. The main reduction system utilizes Gleason spiral bevel gear drive technology, while the wheel-side transmission incorporates an NGW-type planetary reduction gear mechanism. The service braking system features caliper disc brakes, complemented by a drum brake configuration for parking safety.
