Stepper motor planetary gearbox specifications.
The transmission efficiency is high: single-stage stepper motor planetary gearbox reaches 97%~ 98%;
The stepper motor planetary gearbox fails when the output torque exceeds twice.
Working life: the cumulative working time of the stepper motor planetary gearbox at rated load and rated input speed.
The stepper motor planetary gearbox runs smoothly, with low noise and is used for more than 10 times.
Here are the size and matching tolerance of the positioning boss,input shaft and stepper motor planetary gearbox groove of the motor. .
The gears in the stepper motor planetary gearbox are straight-tooth involute cylindrical gears. Has the following characteristics.
Noise: unit dB(A), this value is the input speed of 3000 r/min, no load,1 m away from the stepper motor planetary gearbox measured value.
The stepper motor planetary gearbox has three horizontal series(NGW11-NGW121) and two levels(NGW42-NGW122) three(NGW73-NGW123).
Due to the increase in the number of planetary gears,the length of the second or third stepper motor planetary gearbox will be increased and the efficiency will be decreased.
The stepper motor planetary gearbox is mainly constructed with a sun gear, a planetary gear, an inner ring gear and a planet carrier.
Before installation, wipe away the anti-rust oil of motor input shaft, positioning boss andconnecting part of stepper motor planetary gearbox with gasoline or zinc-sodium water.
Before the motor and stepper motor planetary gearbox are connected, the motor shaft keyway should be perpendicular to the tightening bolt.
Return clearance: when the output end is fixed and the input end is rotated clockwise and counterclockwise to produce rated torque +-2%at the input end, there is a tiny angular displacement at the input end of the stepper motor planetary gearbox, which is the return clearance.
Correct installation, use and maintenance of stepper motor planetary gearbox is an important link to ensure the normal operation of mechanical equipment.
Therefore, when installing the stepper motor planetary gearbox, please be sure to strictly follow the following installation and use of related matters, carefully assemble and use.
Rated input speed of servo planetary gearbox can reach up to 18000rpm(related to the size of the stepper motor planetary gearbox itself, the larger the stepper motor planetary gearbox, the smaller the rated input speed) above, the output torque of industrial grade servo planetary gearbox generally does not exceed 2000Nm.
The specifications of the stepper motor planetary gearbox are divided into 12 frame numbers according to the transmission ratio, power and torque, and single-stage, double-stage and three-stage transmissions. There are 27 frame numbers and 58 speed ratios.
When the output speed is 100 r/min,the life of the stepper motor planetary gearbox is the average life, beyond this value, the average life of the stepper motor planetary gearbox will be reduced.
Correct installation between stepper motor planetary gearbox and mechanical equipment is the same as correct installation between stepper motor planetary gearbox and drive motor. .
The first step is to confirm whether the motor and stepper motor planetary gearbox are ingood condition before installation, and strictly check whether the size of each part connected with the motor and stepper motor planetary gearbox is matched.
Servo planetary gearbox rated input speed up to 18000 RPM(about stepper motor planetary gearbox itself size, the greater the stepper motor planetary gearbox, the smaller the rated input speed) above, industrial-grade servo planetary gearbox output torque is generally not more than 2000 nm, special large torque servo planetary gearbox can do more than 10000 nm.
Because of these characteristics, servo planetary gearbox is mostly installed in the stepper motor and servo motor or brushless motor, used to reduce the speed, improve the torque, matching inertia.
