Features

When the gear motor (motor) generates torque in the same direction as the gear rotation, input pressure oil, and the gear motor (motor) can output torque and speed. Has the following characteristics:

1. The oil inlet and return channels are symmetrical and have the same hole diameter, so that the performance is the same during forward and reverse rotation.

2. Use an external leakage oil hole. On the one hand, there is back pressure on the oil return of the motor, and on the other hand, the oil entering and returning chambers of the gear motor change each other when the gear motor rotates forward and reverse. If internal oil drainage is used, the shaft end oil seal will easily be damaged. Therefore, it is best to use external leakage oil holes for gear motors.

3. The structure of the floating side plate with automatic axial clearance compensation must meet the requirements of working in both forward and reverse rotations. At the same time, the trapped oil unloading groove must also be a symmetrically arranged structure.

4. More rolling bearings are used, mainly to reduce friction losses and improve starting performance.

Structure of Gear Motor

Motor, reducer, and output shaft

The internal structure of a gear motor mainly includes the motor, reducer, and output shaft. The following are the structural components of the motor and reducer:

Electric motor. Provide power source.

Reducer. Composed of a gear shaft and a gearbox, responsible for reducing the output speed of the motor, enabling it to withstand greater loads while increasing torque. It includes the following parts:

Drive gear. It is a crucial part of a gearbox, usually transmitted by power to the gears and then transmitted through other gears. Its shape and size depend on the requirements for power transmission, usually cylindrical or bevel gears.

Driven gear. A gear that transmits force and speed through an active gear, and transmits force and speed to other components. It is usually matched with the driving gear to ensure correct transmission of force and speed.

Bearing. It is an important supporting component used to support gears and other rotating parts. Their design and selection directly affect the operational efficiency and lifespan of the gearbox.

Drive chain. It is a transmission component that connects the driving gear and the driven gear, usually composed of chains or belts. Their material and design depend on the requirements of the gearbox transmission power and speed.

The output shaft transmits the power output from the reducer to the external machine. In addition, the internal structure of the gearbox motor also includes the following parts:

Clutch shaft (or drive shaft). The shaft that obtains power from the engine to further supply power to other shafts.

Spindle. A shaft running at engine speed. It transmits power from the secondary shaft through the use of gears, and operates at different speeds and torques compared to the secondary shaft based on the gear ratio.

Secondary axis. The shaft directly connected to the clutch shaft. It contains gears that connect it to the clutch shaft and main shaft.

Gears are used to transfer power from one shaft to another. The magnitude of torque transmitted through gears depends on the number and size of the gears. The higher the transmission ratio, the higher the torque/acceleration, and the lower the speed. Except for the gears on the main shaft, all gears are fixed on their respective shafts and can slide in any direction along the shaft.
