Control motor: inertia ratio, deceleration increases torque, suppresses resonance, accuracy, economy, space, connection method, self-locking.

Reducer: Match speed, decelerate to increase torque.

Control motor: inertia ratio, deceleration increases torque, suppresses resonance, accuracy, economy, space, connection method, self-locking.

The motor paired with a reducer can achieve small power to drive large loads. Generally speaking, reducers can cause precision loss and power loss.

Gear reducer types: hard tooth surface straight teeth, helical teeth, bevel gears, turbine worm, planetary reducer, harmonic, pendulum, planetary pendulum. Hard tooth surface reducer: coaxial, off-axis, vertical axis, low transmission accuracy, suitable for ordinary motors. Single stage transmission ratio: below 10. Output speed: The output speed of the gearbox. Output torque: The coefficient of the output torque of the reducer is less than the maximum allowable torque. Transmission ratio: The reduction ratio of a gearbox. Machine model: reducer model.

Usage factor: Usage factor * Stage: n=60 * f/P Theoretical speed P4=1500 revolutions per minute P2=3000 revolutions per minute. Calculation of reduction ratio for worm gear reducer: number of turbine teeth/number of worm teeth. The single-stage reduction ratio is large, around 60. The larger the reduction ratio, the lower the efficiency, the lower the transmission accuracy, the frictional transmission, the heat generation, the good compactness of the structure, the high cost-effectiveness of procurement, self-locking, vertical working conditions, and high load impact. Screw jacking machine; Ask the manufacturer. The lifting mechanism of the turbine worm screw has a large lifting force, self-locking properties, and low efficiency. Planetary gear reducer: High precision reducer, directly connected to the motor, clamping type, coaxial reduction, right angle, in terms of accuracy, right angle will be lower.
