1、 High integration of slewing ring reducer The height to width ratio of slewing ring reducer is integrated. The parts and loads that can be driven by slewing ring reducer are dozens of times different, but their specifications, especially the radial specifications of transmission gear, are not different. The advantage of hydraulic motor reducer integration is beneficial to the flat design of the structural form of the connecting parts of the serial transmission system, thus making all mechanical manufacturing smaller.

2、 The safety factor of the rotary support reducer, the rack and pinion drive system, has the characteristics of reverse locking, which can complete the reverse locking, that is, only the worm can be used to push the worm, not the worm can be used to push the worm for fitness. This feature makes the slewing bearing reducer widely used in hoisting, high altitude operation and other machinery and equipment. In addition to improving the technical content of the server, it also improves the working reliability and safety performance of the server. Compared with traditional rotary products, slewing ring reducer has the advantages of simple installation, easy maintenance and more indoor space saving.

3、 Compared with the traditional transmission gear, the simplified server design scheme of slewing bearing reducer can achieve a relatively high transmission ratio. In some cases, the gear rack transmission system can save the reducer components for the server, thus reducing the product cost for customers. In addition, it also greatly reduces the rate of common server failures.

The low steady speed of hydraulic motor is a key performance index of hydraulic motor manufacturers, which has immediate harm to the working characteristics and service life of equipment. The decision elements of the lower stable speed of the hydraulic motor, the lower stable working speed nmmin value of the hydraulic transmission system with the hydraulic motor as the driving force, are determined by the following six elements.

1. The system software selects the leakage flow Qmc characteristic and rolling friction torque damage Tmf characteristic in the low speed range of the hydraulic motor.

2. The flow adjustment equipment of the system software includes pump control, valve control, flow valve speed regulating valve, control,... The output flow characteristics at small flow are relative to the flow required at the low speed range of the motor. It harms the flow characteristics of motor speed change equations.

3. The system software is dragged or manipulated The load properties of the target. It harms the Qmc and Tmf characteristics of the motor and the flow characteristics of the variable speed equipment in operation.

4. The control method of the system software, such as open-loop gain system software, closed-loop control servo control system, etc. It harms the automatic speed regulation characteristics in the low-speed pulsating beverage area.
