Tectonic characteristics
In structure, the main differences between gear motor and gear pump are as follows:
Generally, the gear pump rotates in one direction to reduce the diameter of unbalanced hydraulic pressure, so that the oil suction port is large and the oil discharge port is small. and 2K hydraulic cycloid motor The gear motor needs to rotate in the forward and reverse directions to make the oil intake equal. The internal leakage of the gear motor cannot be directly led to the low-pressure chamber like that of the gear pump, but there must be a separate leakage channel to be led outside the housing. Since the low-voltage chamber of the motor has a certain back pressure, Axial flow distribution cycloidal hydraulic motor If the oil leakage is directly led to all parts connected with the oil leakage channel in the low-pressure chamber, the oil return pressure will be generated under the oil leakage pressure, which will lead to the failure of the shaft end seal.
In order to reduce the starting friction torque of the engine and reduce the stable speed, needle bearings and other measures to improve the lubrication and cooling conditions of bearings are usually used.
Usage: Gear motor has the advantages of small size, light weight, simple structure, good workmanship, non pollution, impact resistance, small inertia, etc.
It is widely used in mining, construction machinery and agricultural machinery. But because the oil pressure acts on Hydraulic motor Because of the small action area, the output torque of the gear is very small, and it is usually used in high speed and low torque situations.
