Swivelling Cylinder Hydraulic Motor
ORBIT NGM - BGM series of swivelling cylinder hydraulic motors are low speed high torque hydraulic motors without connecting staff, It has been widely applied in many kinds of hydraulic transmission system such as plastic injection machine, light industry equipment, heavy metallurgical machinery, petroleum and mine machine, hoist and transport vehicle, ship and deck machinery and equipment etc. In particular, it can be well available in slew driving hoisting capstan and winches wheel slew drives etc.
To avoid leakage and get high volumetric efficiency, a new-style piston ring will be airproofed between the piston and the block. The side loading between the piston and swivelling cylinder has been eliminated; the hydrostatic balance is built between the piston feet; the pistons transmit load to the shaft via a rolling bearing .So this hydraulic motor features high mechanical efficiency and high starting torque. Due to the reduced friction loss in structure and improved sealing capability, so the motor can operateat low speeds with a high degree of speed stability, even if at 1r/min of speed. Hereby the speed control range is wide (the speed control ratio is up to 1000). Because of simple structure, reasonable design (no connecting rod, minish the motor radial size and weight. And using large load capacity bearing.).The series motors has many excellent features as follow light weight ,small size, good reliability, long lifetime and low noise.
