Planetary gear stepper motor supplier are widely used in the coal mining machinery industry. In multi-stage reduction transmission, reasonable allocation of reduction ratio is the key to design, where the more transmission stages, the more complex the calculation of transmission ratio allocation. For the three-stage reducer used in coal mines, the transmission ratio allocation can avoid complex calculations and improve design efficiency.

The working principle of planetary gear stepper motor supplier three-stage transmission is as follows: the sun gear is input by the stage reduction, and then the planetary gear rack is output to the second stage reduction center wheel, and then the second stage reduction planetary gear rack is output to the third stage reduction center wheel, and finally the inner ring gear is output through the third stage reduction. The third stage planetary gear frame is connected to the frame, and the inner ring gears of each stage are fixedly connected.

Planetary gear stepper motor suppliers in the coal mining machinery industry have a wide range of application technologies due to their small size, coaxial input and output data, and the use of load sharing mechanisms, which result in relatively low sensitivity analysis costs for manufacturing or installation system errors. There are many different types of planetary reducers, among which the traveling research mechanism of coal mine excavator can output large torque, low traveling speed and large transmission ratio, so it is necessary to adopt three-level comprehensive transmission at the same time. The primary task in designing multi-stage transmission reducers for this type is to allocate the actual transmission ratio. The problem of reasonable transmission ratio allocation requires constantly meeting the requirements of the management strength and geometric shape of the gearbox at all levels.
