BM cycloidal hydraulic motor is a small low-speed high torque hydraulic motor with single axis flow distribution and fixed rotor set. Its advantages are as follows: 1. It is small in size and light in weight, and its overall size is much smaller than other types of hydraulic motors with the same torque. 2. Wide speed range, stepless speed regulation, minimum stable speed up to 15 rpm, convenient installation and layout, low investment cost. 3. It can be used in series or parallel in the hydraulic system. 4. The moment of inertia is small, and it is easy to start under load. It can rotate in both forward and reverse directions, and it does not need to stop when reversing. BM cycloidal motor is widely used in agriculture, fishery, light industry Cycloidal motor of overhead crane Price The slewing mechanism of hoisting and transportation, mining, construction machinery and other machinery. Examples of BM cycloidal hydraulic motor used abroad; 1) Agricultural use: various combine harvesters, seeders, rotary tillers, lawn mowers, sprayers, feed mixers, ground drills. 2) Fishery use: net lifter. special-purpose Cycloidal motor of overhead crane 3) Light industry: commercial winding machines, textile machines, printing machines, washing machines. 4) For construction industry: road roller, cement mixer, sweeper.

1) Select the hydraulic pump or motor with good quality and conduct regular maintenance. For example, if the tooth profile accuracy of the gear is low, grind the gear to meet the requirements of the contact surface; 2) If the vane pump has trapped oil, the triangular groove of the oil distributor should be corrected to remove the trapped oil; 3) If the axial clearance of the hydraulic pump is too large and the oil delivery is insufficient Cycloidal motor of overhead crane Price Repair to keep the axial clearance within the allowable range; 4) If the hydraulic pump is not selected correctly, it should be replaced immediately. 3. The reversing valve is improperly adjusted. Improper adjustment of the reversing valve causes the valve core of the reversing valve to move too fast, resulting in reversing shock, noise and vibration. During operation, the valve core branch of hydraulic valve Kaifeng Cycloidal motor of overhead crane Support on the spring. When its frequency is close to the pulsating frequency of oil delivery rate of hydraulic pump or other vibration sources, vibration and noise will be generated.

Its basic types are gear type, screw type, vane type and axial plunger type. Its main characteristics are high speed, small moment of inertia, convenient starting and braking, adjustment (speed adjustment and special-purpose Cycloidal motor of overhead crane Reversing) High sensitivity. As the output torque of high-speed hydraulic motor is generally small, it is also called high-speed small torque hydraulic motor. Its basic type is radial plunger type, in addition, there are axial plunger, vane type, gear type and other structural types. Low speed hydraulic motors are mainly characterized by large displacement, large volume and low speed (sometimes Cycloidal motor of overhead crane Price It can rotate a few revolutions per minute or even a few revolutions per minute), so it can be directly connected to the working mechanism; It does not need a speed reducer, greatly simplifying the transmission mechanism. Usually, the output torque of low-speed hydraulic motor is large, so it is also called low-speed high torque hydraulic motor.

Oil filling process sequence: shell oil filler → oil filling sleeve groove → oil filling sleeve groove → shell oil filling hole → diaphragm → stator. Oil drainage process sequence: rotating stator → diaphragm Cycloidal motor of overhead crane Price → Shell oil distribution hole → oil distribution jacket longitudinal groove → oil distribution jacket groove → shell oil return port. The rotating motion of the rotor includes rotation (rotation in the direction of expanding the high-pressure cavity around the center of the rotor) and revolution (rotation in the direction of deviation from the radius around the center of the stator). The rotation of the rotor is opposite to the revolution direction, and the rotation is transmitted to the output shaft through the linkage shaft. Rotor rotates for 1 cycle special-purpose Cycloidal motor of overhead crane The rotor is driven by 42 pressure oil with the maximum volume for 6 revolutions, so the motor has a large emissions.

1. The hydraulic system is characterized by high energy density. For motors with the same power, hydraulic motors are much smaller and lighter than motors. And it is easy to apply to mobile devices. 2. The hydraulic motor has convenient speed regulation, which can be adjusted infinitely from 0 to the maximum speed according to the adjustment of the hydraulic valve. The motor itself does not need special design and has low cost. This is much cheaper than motor+reducer, or variable frequency motor and servo motor. 3. The hydraulic motor is totally enclosed and can be safely used in dusty, wet (even underwater) and flammable environments, which is much more reliable than explosion-proof (flameproof) motors. 4. The hydraulic system has strong anti overload capacity, and it is protected by the overflow valve, allowing long (relatively) frequent overloads. It is easy to recover under overload conditions, without damaging the equipment or restarting the equipment. These unparalleled advantages of motors have made hydraulic motors and hydraulic technology rapidly spread and popularized all over the world in the past 20 years. People increasingly feel the importance of hydraulic motors in practice.

Functions: It is used for the storage, supply and recovery of hydraulic media, the connection between hydraulic components and the transmission of energy carrying hydraulic media, filtering impurities in the hydraulic media, keeping the media required for the normal operation of the system clean, heating or cooling the system, storing and releasing hydraulic energy or absorbing hydraulic pulsation and impact, and displaying the pressure and oil temperature of the system; Hydraulic working medium: various hydraulic oils (fluids), efficacy: as the energy carrying medium of the system, it plays the role of lubrication and cooling while transferring energy. Generally speaking, the hydraulic components that can complete certain specific functions are called hydraulic circuits. In order to meet the working requirements of certain machinery or equipment, the overall structure of several special basic functional circuits connected or combined together is called hydraulic system.
