HGM Swing cylinder motor （ Internal five-star motor ）The hardness of the HGM series motor housing is improved, and the bearing capacity of the internal dynamic components is improved. It has a high continuous power range, high mechanical efficiency and volumetric efficiency, which reduces the internal unit load, thus reducing the heat generation and related negative effects.
1. Product Introduction
Small structure, mainly used in plastic machinery equipment, rubber and plastic machinery, metallurgical equipment, mining equipment, lifting and conveying equipment, heavy machinery equipment, crude oil mining equipment, ship deck machinery, machine tools, plastics, geological exploration and other machinery Hydraulic transmission In the system, it is especially suitable for improving transmission machinery such as winch, drum machinery, various rotary machinery drive, crawler and wheel travel mechanism drive. Especially when the excavator is changed to the drill.
2. Product characteristics
1. Since there is no lateral force between the piston and the swing cylinder, the bottom end of the piston is transformed into static pressure balance, and the torsion is transmitted between the piston and the crankshaft by rolling bearings, which reduces the friction loss during the force transmission process. Therefore, GM series Hydraulic motor It is characterized by high mechanical efficiency and high starting torque (the starting mechanical efficiency is above 0.92).
2. The plane valve distributor is simple and reliable, with good sealing performance and very little leakage. The piston and swing cylinder are sealed with plastic piston rings without leakage, so the volume ratio is very high (up to 0.98).
3. Since the friction loss is reduced in structure and the sealing performance is improved, the low-speed stability is good, and it can operate stably at 1r/min, and the speed regulation range is large (the speed regulation ratio can reach 1000).
4. Since the piston and bearing sleeve are firmly stuck through the snap ring without clearance, this series of hydraulic motors can operate under pump conditions, and when the oil inlet is closed, the motor can operate at high speed under free theory conditions.
5. The pressure of this series of hydraulic motors is high, and the higher pressure can reach 45MP. Light weight, small size and high specific power.
6. In view of the compact structure, reasonable design, and large load capacity bearing, the transmission shaft is allowed to bear radial load, and the rotation angle can be reversed.
In view of the above characteristics, AKS series hydraulic motors are widely used in the hydraulic transmission systems of plastic machinery equipment, rubber and plastic machinery, metallurgical equipment, mining equipment, lifting and conveying equipment, heavy machinery equipment, crude oil mining equipment, ship deck machinery, machine tools, plastics, geological exploration equipment and other machinery. It is especially suitable for improving transmission machinery such as winch, drum machinery, various rotary machinery drive, crawler and wheel travel mechanism drive.
