BM4 Cycloid Hydraulic Motor for Agricultural Machine

Feature of BM4 Hydraulic Motor

• The forward and reverse conversion is convenient and the speed is stable.
• Embedded stator and rotor design, high oil distribution accuracy, and high mechanical efficiency.
• A double rolling bearing design can withstand higher lateral force.
• Imported shaft seals are designed to withstand high back pressure and can be used in series or parallel.
• Various installation and connection forms of the flange, output shaft, oil port, etc.

We can also supply all the parts for the feed mixer.

Driving Principle of Hydraulic Motor

The high-pressure oil enters the low-pressure oil in the hydraulic motor and exits the low-pressure oil in the pump.
The driving shaft of the hydraulic motor is connected with the driving shaft of the pump (coaxial), which drives the pump to rotate when the hydraulic motor rotates.
The hydraulic pump and hydraulic motor are hydraulic components that can work reversibly. The working fluid input to any hydraulic pump can make it become the working condition of the hydraulic motor; On the contrary, when the main shaft of the hydraulic motor rotates by the external torque, it can also become the working condition of the hydraulic pump. Because they have the same basic structural elements, sealed but periodically changeable volumes, and corresponding oil distribution mechanisms.
There are still many differences between the same type of hydraulic motor and hydraulic pump. As the working conditions of hydraulic motors and hydraulic pumps are different, their performance requirements are also different. First, the hydraulic motor should be able to rotate forward and backward, so its internal structure is required to be symmetrical; The speed range of the hydraulic motor needs to be large enough, especially the minimum stable speed. Therefore, it usually adopts a rolling bearing or hydrostatic sliding bearing; Secondly, because the hydraulic motor works under the condition of input pressure oil, it does not have the ability of self-priming but requires a certain initial sealing to provide the necessary starting torque. It is precise because of these differences that hydraulic motors and hydraulic pumps are similar in structure, but can not work reversibly.

Application of Hydraulic Technology in Agricultural Machinery

At present, the application of hydraulic technology in agricultural machinery is mainly in the following aspects:

(1) agricultural machinery used for bulk food crops. It mainly includes tractors, agricultural farming machinery, seeders, and harvesters that are common in agricultural machinery. They can achieve the functions of tillage, sowing, fertilization, harvesting, transportation, etc. in agricultural production through different mechanical designs.

(2) Agricultural robots, manipulators, and other automatic equipment in the new direction of agricultural machinery science and technology research and development. Hydraulic systems can provide action, power, motor power, and other support for new technology agricultural machinery. Their applications include intelligent seeders Highland an automatic plant protection machine and other agricultural machinery in Xiangjiang.

(3) For agricultural machinery used for cash crops, the models involved in the hydraulic system include large translational cotton intercropping machinery and fruit harvesting machinery. The application of hydraulic technology in agricultural machinery and the development of mechanical design and manufacturing from pure machinery to electromechanical integration are conducive to the realization of fine agriculture
