Orbital Hydraulic Motor BMR-80

About product

The Orbital Hydraulic Motor BMR 80 is a specific model of hydraulic motor that falls under the category of low speed, high torque hydraulic motors. As an orbital hydraulic motor, it operates based on an orbital principle, where an eccentric shaft causes an orbiting motion of the internal components.

Low speed high torque hydraulic motors like the BMR 80 are known for their durability and longevity. They are built to withstand harsh operating conditions, including high pressures, temperature variations, and contamination. This ensures reliable performance and minimizes downtime in industrial environments.

  • The motor’s driver-linker design prolongs its operating life.
  • The distribution system is specially designed to meet low noise requirements.

Product Detail

Orbital Hydraulic Motor For Sale –  BMR 80

The BMR series hydraulic motors are known for their compact size, reliability, and durability. Being a low speed high torque hydraulic motor, the BMR 80 is exceptionally well-suited for a diverse range of applications in both mobile and industrial equipment where space limitations and the demand for high torque capabilities are of utmost importance. Specifically, in the context of ship propulsion, the orbital hydraulic motor’s wide range of working chamber sizes, varying from 50 to 375 cm3/rev, enables it to efficiently power marine vessels while effectively navigating the challenges posed by limited space and the need for robust torque output.

Built on the gerotor design principle, the BMR series orbital hydraulic motors feature a rotor with rounded teeth that moves along the rollers of a fixed gear. This design enables these ship motors to deliver high starting torque and maintain stable operation, ensuring a constant speed at the output shaft. The gerotor design also makes these motors highly effective in challenging operating conditions, such as applications with elevated pressures, low-viscosity working fluids, frequent reversals, and high loads on the output shaft.

Orbital Hydraulic Motor Features –  BMR80

  • Advanced manufacturing devices for the Gerolor gear set ensure smooth operation, reliability, and high efficiency.
  • The shaft seal is designed to withstand high back pressure, allowing for parallel or series usage.
  • The motor’s driver-linker design prolongs its operating life.
  • The distribution system is specially designed to meet low noise requirements.
  • The ship motor has a compact volume, making it easy to install in various applications.

Gerotor Gear Of BMR 80 Orbital Hydraulic Motor

The BMR-80 Orbital Hydraulic Motor utilizes a Gerotor gear set, which is a type of positive displacement gear mechanism. This gear set consists of an outer ring with internal teeth and an inner gear with external teeth. The inner gear is connected to the motor shaft and rotates eccentrically within the outer ring.

As the hydraulic fluid enters the ship motor, it flows into the cavities formed between the outer ring and the inner gear. The rotation of the inner gear causes the fluid to be trapped and carried around the outer ring, creating a positive displacement effect. This displacement generates torque and rotational motion in the motor shaft, allowing it to drive various hydraulic systems.

The Gerotor gear set design in the BMR-80 ensures efficient fluid distribution, smooth operation, high pressure capabilities, and a long service life. It is a reliable and effective mechanism for converting hydraulic energy into mechanical power.
