Gear Motors

Gear Motors – Low Initial Cost, High RPM, Higher Tolerance to Contamination and Durability.

The most common type of hydraulic motor is the gear type. Gear motors, unlike the piston or vane type motors, are less susceptibility to contamination.

A gear motor is a positive fixed displacement motor that develops an output torque at its shaft by allowing hydraulic pressure to act on gear teeth. Gear motors are primarily used to reduce speed in a series of gears, which in turn creates more torque. Simple in construction, a gear motor develops torque due to the hydraulic pressure acting on the surface of the gear teeth.

There are Two Types of Gear Motors:

  • External Gear Motor; both meshing gears have teeth on their outer circumferences. The type of gear used in this motor is most commonly a spur gear.

 

  • Internal Gear Motor; consists of one external gear that meshes with the teeth on the inside circumference of a larger gear. There are two versions of the Internal Gear Motors:
    • Gerotor Motor (popular in mobile systems, mobile hydraulic technology)
    • Geroler
