Abstract
The present disclosure relates to a machining head for a gear manufacturing machine having at least one driven motor spindle and at least one counter-spindle, wherein a tool arbor having at least one tool arranged thereon is mounted between the motor spindle and the counter-spindle, and wherein at least one balancing device is integrated within the driven motor spindle and at least one balancing device is integrated within the counter-spindle.
Claims15
A machining head for a gear manufacturing machine, comprising:
- at least one driven motor spindle including at least one balancing device integrated within the at least one driven motor spindle;
- at least one counter-spindle including at least one balancing device integrated within the at least one counter-spindle;
- and
- a tool arbor having at least one tool arranged thereon mounted between the motor spindle and the counter-spindles;
- wherein the at least one balancing device integrated within the at least one driven motor spindle is completely or almost completely included within a housing of the motor spindle and is integrated into a rotor of the motor spindle, and wherein the at least one balancing device integrated within the at least one counter-spindle is completely or almost completely included within a housing of the counter-spindle and is integrated into a shaft of the counter-spindle.
2 more elements
A gear manufacturing machine, comprising:
- a control system;
- and
- a machining head, including:
- a first balancing device positioned within a motor-driven spindle;
- a second balancing device positioned within a counter-spindle;
- a tool arbor mounted between the motor-driven spindle and the counter-spindle;
- and
- a signal transmitter;
- wherein the control system is configured to receive vibration parameters from the signal transmitter of the machining head;
- and
- wherein the control system includes instructions stored in non-transitory computer memory to adjust positions of the first balancing device and the second balancing device in response to the received vibration parameters, a spindle speed, or an angular position of the motor-driven spindle.
