Checkpoints

Installation of Clutch

The clutch is made from the softer iron material. Be cautious against falling or impacts when mounting. An inappropriate pressing or knocking will cause transformation. In order to protect bearings, please do not knock bearings as well.

Varistor / Voltage Dependent Resistor (VDR)

It will result in the reverse surge when switching on/off the DC side. Under this circumstance, the coil and the switch contacts will be burned out due to overheating, which may lead to harmful effects on the equipments connected to. Please use suitable VDR and apply a parallel connection with coil to make discharge circuit.

Supply of Voltage

Since the tooth clutch is transmitted torque through excitation voltage, the voltage has impacts on torque. Please control the variation of voltage within ±5%. Additionally, even though the voltage supply complies with standards, the voltage will be reduced due to excessive high resistance if the length of lead wires extends too long. While power is supplied, please check the excitation voltage from where the terminal connects and ensure it meets standards. Do not pull and drag the lead wires too much or bend it perpendicularly.

Installation of butt-shafts

The tooth clutch is generally for through-shaft mounting. When apply it on butt-shafts mounting, please align one of the shafts with bearing and pay attention to the concentricity between two shafts.

Tooth tip engagement

If the tooth clutch is connected in static status, the tooth may not engage to each other properly, there will be slippage on tooth tip due to high torque generated by accelerated speed during operation. Please design a proper start control program for motor to reduce the accelerated torque. Or please select a clutch with torque higher than motor’s. Besides, clutch should be connected at low speed, please refer to specification for allowable speed.
