Shaft for Rotationally Coupling a Main Device to a Tubular Device

摘要

A shaft for rotationally coupling a main device to a tubular device includes a first free end that is configured to be introduced into the tubular device, and a second end configured to be secured to the main device. The shaft also defines at least a first bearing region along an outer circumference that is configured to form a contact in a hollow accommodating region of the tubular device, and further includes at least one torque-transmitting section configured to engage with a torque-transmitting section of the tubular device. A securing device of the shaft includes a locking device that, in a locked state, is configured to prevent the securing device from being dismounted, and that, in an unlocked state, is configured to enable the tubular device to be dismounted. The securing device further includes an interlocking device that is arranged on the first end of the shaft, and that enables locking and unlocking the locking device.

主权项

1. A shaft for rotationally coupling a main device to a tubular device such that a torque can be transmitted between the main device and the tubular device via the shaft, comprising:
a first, free end configured to be introduced into the tubular device to mount the shaft with the tubular device; a second end that faces away from the first end, and that is configured to fasten the shaft to the main device; and a securing device that is arranged on the shaft, and that is configured to at least axially secure the tubular device on the shaft, the securing device including:
a blocking device that is arranged on the securing device and that is configured to block the securing device against removal from the shaft when positioned in a locked state, and enable removal of the tubular device when positioned in an unlocked state;a further blocking device that is arranged on the securing device and that is configured to lock and unlock the blocking device; anda locking device arranged at a first end of the shaft; wherein the shaft defines, along an outer circumference thereof, at least one first supporting region which is configured to come into contact in a hollow receiving region of the tubular device when the tubular device is mounted on the shaft, the outer circumference further defining at least one torque-transmitting section which is configured to engage with a torque-transmitting section of the tubular device.
