Product Overview

 

The RM58952573 planetary gear torque hub is an integrated hydraulic wheel drive reducer specially matched for Ingersoll Rand and Volvo SD100 single-drum road rollers. It combines multi-stage planetary reduction mechanism, load-bearing installation flange and built-in parking brake as one assembly. Matched with hydraulic travel motor, it converts high-speed low-pressure hydraulic power into low-speed high-torque output to drive the compaction steel drum. As a core OEM replacement hydraulic spare part for road compaction machinery, it fully matches the original installation dimensions, oil circuit interface and load parameters of the original unit, realizing direct plug-and-play replacement.

 

Features and Values

Core Features

  • Multi-stage planetary gear transmission structure, forged alloy steel gears with quenching treatment, outstanding impact resistance and bearing capacity.

  • Integrated heavy-duty mounting flange, bears the full vehicle weight and frequent compaction impact loads simultaneously.

  • Built-in safety wet parking brake, locks the drum tightly when power cuts off to prevent roller sliding on slopes.

  • Full set of high-pressure wear-resistant sealing components, effectively avoid oil leakage under long-time heavy-load continuous operation.

  • Strictly consistent with original OEM size, spline shaft and oil port layout, no modification needed during installation.

 

Core Values

 

  • Perfect replacement solution to cut down machinery maintenance cost compared with expensive original factory assemblies.
  • Stable high-torque output guarantees consistent compaction performance on construction sites.
  • Integrated brake & reducer design simplifies assembly steps and shortens equipment downtime for repair.
  • Wear-resistant durable structure extends service life, reduces frequency of secondary replacement and construction delay losses.

 

Typical operating scenarios and working conditions

 

 

  • Highway, municipal road, village road foundation and surface compaction construction
  • Industrial plant ground, parking lot, landfill and large venue foundation rolling work
  • Road maintenance, pavement renovation and slope soil compaction projects
  • Long-time continuous heavy-load operation under medium-high hydraulic pressure

  • Complex rugged construction sites with frequent bumping, impact and dust pollution

  • Flat ground, ramp and slight gradient construction environments (supported by built-in parking brake for slope parking)

  • Wide temperature working range: adapt to outdoor construction in hot summer and cold winter

  • Severe dust, mud and splashing water working environment with reliable sealing protection
