Description

Rexroth piston motor is a type of hydraulic motor. The working medium (hydraulic oil) in the piston

Its working principle is: the working medium (hydraulic oil) in the end surface of the piston or plunger, piston or plunger do reciprocating motion, through the motion conversion mechanism (swash plate, cam, crank, etc.), or the piston of the reciprocating plunger motion into circular motion of the output shaft.

use

Rexroth piston motor, also known as motor oil, mainly used in injection molding machinery, ships, from Jan machines, construction machinery, construction machinery, mining machinery, mining machinery, metallurgical machinery, shipbuilding, machinery, petrochemical, port machinery, commercial vehicles, roads, public works and utilities.

Speed motor gear motor with small size, light weight, simple structure, good technology, not sensitive to oil pollution, the impact resistance and inertia is small. The disadvantage greater torque ripple, low efficiency, starting torque is small (only 60% of the rated torque - the 70%) and poor low-speed stability.

classification

Hydraulic motor according to the structure type points, can be divided into gear, vane, piston motor Rexroth Rexroth piston motors and other types. According to the rated speed of the hydraulic motor is divided into two major categories of high and low speed. Higher than the rated speed 500r / min belongs to the high-speed hydraulic motors, lower than the rated speed 500r / min belongs to the low-speed hydraulic motor. The basic types of high-speed hydraulic motor gear, screw, vane and axial piston like. Their main feature is a high speed, small moment of inertia, easy starting and braking, adjusting the high (speed and commutation) sensitivity. Speed hydraulic motor output torque is usually not so called high speed low torque hydraulic motor. The basic types of low-speed hydraulic motors are radial piston type, in addition to the axial piston, vane and gear also has low structural type, the main features of low-displacement hydraulic motor is large, bulky low speed (sometimes even turn up a few tenths revolutions per minute), it can be directly connected with the working bodies; no deceleration devices, so that the transmission mechanism greatly simplified, usually low-speed hydraulic motor output torque is large, it is also known as the low speed and high torque hydraulic motor.
