21 Ton Road Roller Drive Axle
1. Gleason spiral bevel gears in the main reducer ensure high transmission efficiency with low operational noise.
2. NGW planetary gears provide compact design and efficient power transmission.
3. Steel-cast axle housings deliver high load capacity and rigidity, with multiple standardized connection options.
4. Disc-caliper service brakes achieve high braking torque with consistent reliability.
5. Drum-type parking brakes ensure fail-safe operation and long-term safety.
6.Installed on 19 - 23 ton road rollers
Introduction:
The 19-23 ton vibratory road roller features a two-stage gear reduction system. Its cast steel axle housing supports a primary Gleason spiral bevel gear drive for main reduction, paired with an NGW planetary gear mechanism at the wheel side. The braking system combines caliper disc brakes for service operation and drum brakes for parking safety.
