Oms 160 Hydraulic Motor
◎Advanced stator and rotor parameters design, with low starting pressure, high efficiency and stable low speed operation;
◎High operating pressure and high output torque;
◎Advanced shaft seal design, with high back pressure bearing capacity;
◎Advanced and reliable linkage shaft design, with a long motor service life;
◎Advanced oil distribution mechanism design, with high oil distribution accuracy and automatic wear compensation;
◎The motors can be used in series and parallel; when they are connected in series, they should be connected to the external drain pipe;
◎Tapered roller bearing support design, with a large radial load carrying capacity, so that the motor can be used directly drive the operating mechanism.
- Product Introduction
The ZMS series orbital hydraulic motor developed and produced by our company is divided into multiple sub-series such as ZMS, ZMSW, ZMSS, ZMSJ, and ZMSB. According to the different displacement and connection parameters, the product can replace various series of orbital motors on the market, such as OMS, 2K, BM5, and BM3.
The ZMSW series is a mechanism commonly used for the rotation of the drive wheel, so better performance is required to meet the driving needs of the equipment. In addition, in order to prevent the smooth operation of the equipment and the equipment from being bumped during operation, the shorter the motor size, the better. In addition to its excellent performance, this motor of ours has a more compact design.
Our ZMSS series motors are bearingless motors, mainly suitable for coal mine drilling rigs.
The ZMSJ series motors are our large flanges, and the flange and Flange Counterbore sizes are relatively large. This type of motor is more used in fishing machinery.
The ZMSB series motors have a braking function. The overall length of this motor is longer than that of ordinary motors because this motor requires more space to install related parts. When choosing this motor, the static braking torque is the main parameter to pay attention to, which is closely related to the load.
