Dual-drive tandem motor electro-spindle
2015
The invention provides a large-torque, low-calorific value and energy-saving dual-drive tandem motor electro-spindle. The dual-drive tandem motor electro-spindle comprises an electro-spindle shell, wherein a first spindle front bearing housing and a first spindle rear bearing housing are mounted in the front of the interior of the shell; a first spindle penetrates the first spindle front bearing housing and the second spindle rear bearing housing through bearings; a first motor rotor is mounted on the first spindle; a first motor stator is arranged on the outer side of the first rotor. The dual-drive tandem motor electro-spindle is characterized in that a second spindle front bearing housing and a second spindle rear bearing housing are mounted in the shell at the rear end of the first spindle, a second spindle is mounted between the second spindle front bearing housing and the second spindle rear bearing housing through bearings, a second motor rotor sleeves the second spindle, a second motor stator is arranged on the outer side of the motor rotor, a bellows coupling sleeves the rear end of the first spindle, an electromagnetic clutch is fixed at the front end of the second spindle, and the electromagnetic clutch and the bellows coupling are mutually connected.
