Network optimization information:

Speed: In the past 20 years, with the deepening of people's understanding of a series of problems such as vibration, high noise and slow life caused by the increase of motor speed, some technical problems have been broken through, and the motor speed has also been greatly improved. For example, AZFMS inclined shaft type Axial plunger hydraulic motor Its speed is 11000rpm, pressure is 35MPa, and volume is 4.93mL/r. With the rapid development, Low speed high torque hydraulic motor The low speed stability has been improved to a certain extent Hydraulic motor It can operate stably at 0.2 rpm or lower. For example, the INM6-1600 hydraulic motor of Ningbo Yining can operate continuously at 0.2~250 rpm, Domestic cycloidal motor The operating speed is 400rpm, and the pressure is 45MPa.

Torque output: Low speed high torque hydraulic motor Large torque output can greatly simplify the transmission system requiring large torque, which is conducive to improving transmission efficiency. At present, the output torque of low speed and high torque hydraulic motor can reach hundreds of thousands of Nm, such as NJM-E40 Inner curve motor The output torque is 114480Nm, the pressure is 25MPa, the rated pressure is 16MPa, the speed is 12rpm, and the output power is 40000mL/r.

Oil temperature: in the 1980s, the general working oil temperature specified in the technical regulations was 60 ℃; Now, technological progress has broken this limit, and the oil temperature can be much higher than this value. For example, the working oil temperature of CMA and CMS series gear motors is between - 20 and 95 ℃.
