Speed ​​reducer speed adjustment method:
The gear deceleration motor is a fixed-speed deceleration motor. Once the speed ratio is selected, the motor is selected and the final output rotation speed is fixed. However, in actual use, there are many occasions that require changes in speed, such as the speed of the spindle of the lathe, the speed of the agitator shaft of various agitators, the speed of the conveyor when conveying different items, etc. How the speed is adjusted is of great concern to engineering technicians. topic of.
1. Step-change speed-changing pole-changing speed control is the simplest and most economical speed-adjustment method. However, it is limited to small and medium capacity (below 2kw) and occasions where the number of starts is small. Usually only two speeds can be achieved, the speed ratio that can be achieved is also smaller (l:2 to 6), and the limit is achieved in three gears; in certain specific industries, such as lathes, gearboxes with gears are often used. Speed ​​adjustment. Although there are child speeds, the speed range is not large.
2. Stepless speed regulation can be divided into mechanical and electrical. The former is a common method of inserting mechanical stepless speed regulating devices (mainly belt pulley type, friction disc type) at the joint between the motor and the gear box. Its advantages are stable speed, structure is not complex, suitable for harsh environments; the disadvantage is that the speed range is small (usually within 1: lO) basin belts and friction discs are consumables, requiring regular maintenance and replacement. The latter is the cascade speed control of asynchronous motors, rotor resistance or DC motor speed regulation.
