Shaft for Rotationally Coupling a Main Device to a Tubular Device

A method for producing a shaft, comprising:

• inserting a further blocking device into a securing device configured to at least axially secure a tubular device on the shaft;
• the shaft having a first free end configured to be introduced into the tubular device to mount the shaft therewith, a locking device arranged at a first end of the shaft, and a second end facing away from the first end and configured to fasten the shaft to a main device,
• the shaft defining (i) an axial recess that extends from an end side of the first end, (ii) a lateral recess transverse to the axial recess, the lateral recess having a first opening on an outer circumference thereof, and (iii) along an outer surface of the shaft, at least one first supporting region which is configured and arranged 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, and
• 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, the further blocking device being configured to lock and unlock the blocking device;
• inserting a spring into the axial recess;
• after the spring is inserted into the axial recess, pushing the securing device together with the blocking device until the blocking device protrudes through the first opening;
• mounting the securing device in the shaft;
• and
• placing a cap configured to act as an actuating element onto an end of the securing device protruding from the shaft.

A system comprising:

• a machine tool that includes:
• a receptacle;
• and
• a shaft received in the receptacle, the receptacle being configured to drive the shaft in at least one of a rotating and oscillating manner;
• and
• at least one tubular device which is drivable by the machine tool and which has a tool, wherein the at least one tubular device includes a set of tubular devices which are optionally drivable by the machine tool;
• the shaft having:
• 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;
• and
• a 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 and arranged 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.
