| Electromagnetic Multiple-disc clutches with slipring E1TM…2 |
 |
Type E1TM…2 clutches are designed for remote automatic control of machine tools and other machinery drives. They find wide use in automatic gear boxes, feed boxes, feed drives and also in starting devices. They ensure rapid starting of drives under load, low losses at idling what affects favourably the heat balance of machine, protects drives against pulse overload and if selected and assembled correctly - long service life and reliability.
|
| The clutches must be lubricated/cooled with gear oil of a viscosity of 1.7 to 2.20° C at 50° C. Supply voltage - 24 V DC. The negative terminal of the source of current is to be connected to the machine body and the positive terminal - to brush holder. In order to protect the coil against breakdown when the current is switched off a suppressor should be incorporated in the supply system in the form of a resistor of a resistance 8 to 10 times higher than the coil resistance and a rating of 2 to 10 W, connected in parallel to the coil, or a semiconductor diode or a resistor and coil. |
 |
|
|
Exceeding circumferential speed of the contact ring above 20 m/s should be avoided whilst at speeds above 10 m/s additional brush holder is recommended. The clutches do not require adjustment in service. Maximum clutch shaft run-out is 0.02 mm. The accessories for each clutch include a brush holder (EMB 2A) and 2 spare brushes. The duty of the brush holder is to provide supply voltage to the clutch coil.
