Do you know the types of hydraulic motors? According to its structure type, it can be divided into gear type, blade type, plunger type and other types. This article will introduce the characteristics of different types of hydraulic motors.
1. Gear motor: in order to adapt to the requirements of forward and reverse rotation in the structure, the oil inlet and outlet ports are equal, symmetrical, and there is a separate oil leakage port, which leads the leakage oil of the bearing part out of the shell; This kind of motor due to poor sealing, low rental efficiency, input oil pressure can not be too high, can not produce large torque. And the instantaneous speed and torque change with the position of the meshing point, so the gear hydraulic motor is only suitable for high-speed and small torque occasions. It is generally used in construction machinery, agricultural machinery and mechanical equipment with low requirements for torque uniformity.
2. Vane type: Due to the action of pressure oil, the unbalanced force causes the rotor to generate torque. The output torque of the vane hydraulic motor is related to the pressure difference between the displacement of the hydraulic motor and the oil inlet and outlet of the hydraulic motor, and its speed is determined by the flow rate of the input hydraulic motor. Vane type hydraulic motor has small size, small moment of inertia, sensitive action, and can be applied to occasions with high commutation frequency; However, the leakage is large and unstable when working at low speed. Therefore, vane hydraulic motors are generally used in occasions with high speed, small torque and sensitive action requirements.
3. Radial plunger type: working principle, when the pressure oil enters the bottom of the plunger in the cylinder through the window of the fixed oil distribution shaft 4, the plunger extends outward and tightly presses against the inner wall of the stator, because there is an eccentric distance between the stator and the cylinder block. At the point where the plunger is in contact with the stator, the reaction force of the stator on the plunger is . The force can be broken down into two components. When the oil pressure acting on the bottom of the plunger is p, the plunger diameter is d, and the angle between the force and is X, the force generates a torque on the cylinder block and makes the cylinder rotate. The cylinder block then outputs torque and speed outward through the transmission shaft connected by the end face.
