Precision gear really own speed it?
买一套棋牌app需要多少 www.jbqtck.com.cn Precision gear essence is based power control. Kind of power control principle, one is electromagnetic power control, the changes are ideal no-load motor speed, precision gear speed is highly efficient energy-saving speed; the other is the loss of power to control, increasing the motor speed drop, tone speed is low efficiency, energy consumption and speed governor. Expressed as the difference between the motor speed universal ideal no-load speed and speed drop of all motor control methods are being attributed to the power control principle, or the slave electromagnetic power control principle, or power control principle dependent loss.
Precision gear the motor speed methods and performance mechanism closely linked with the governor, the governor pointed out the development direction of the exchange. According to the theory that we are now respected high efficiency inverter only one speed, but speed is not the only method of speed control motor. Within chopper fed only control speed and frequency control gear motors different objects look three-step selection have basic tasks:
1, Determine the operating speed machinery, reduction ratio calculated in accordance with the small motor speed;
2, calculate the load torque, according to the motor output torque select a small, small motor to determine the model;
3, to determine the additional function of small motor, such as power brakes, power brakes, a combination of speed, separation speed, reversible operation, and some additional features that only certain plants can offer.
Precision gear includes: gear cutting, gear motors, gear cutting, worm, continuously variable transmission, gear commutator, worm reducer, screw lift, micro-cycloid reducer, precision planetary reducer, spiral bevel gear reducer, helical gear reducer, reducer parts processing.
