Abstract
A coupling for connection between a first shaft and a second shaft includes a first coupling portion designed for connection to the first shaft, a second coupling portion connected to the first coupling portion for transmitting a drive torque and designed for connection to the second shaft, and a bush accommodated in a through-hole of an axial hub portion of at least one of the first and second coupling portions and made of an electrically non-conductive high-performance plastics material, for receiving the first shaft or second shaft associated with the at least one of the first and second coupling portions, wherein the through-hole has an internal circumference formed with a radial step.

A coupling for connection between a first shaft and a second shaft, the coupling comprising:
- a first coupling portion designed for connection to the first shaft;
- a second coupling portion connected to the first coupling portion for transmitting a drive torque and designed for connection to the second shaft;
- and
- a bush accommodated in a through-hole of an axial hub portion of at least one of the first and second coupling portions and made of an electrically non-conductive high-performance plastics material, for receiving the first shaft or second shaft associated with the at least one of the first and second coupling portions, wherein the through-hole has an internal circumference formed with a radial step.
A drive train of a rail vehicle, the drive train comprising:
- a first shaft in the form of a drive shaft;
- a second shaft in the form of an output shaft;
- and
- a coupling designed to couple the first shaft to the second shaft in a torque-transmitting manner to a second shaft, said coupling comprising a first coupling portion designed for connection to the first shaft, a second coupling portion connected to the first coupling portion for transmitting a drive torque and designed for connection to the second shaft, and a bush accommodated in a through-hole of an axial hub portion of at least one of the first and second coupling portions and made of an electrically non-conductive high-performance plastics material, for receiving the first shaft or second shaft associated with the at least one of the first and second coupling portions, wherein the through-hole has an internal circumference formed with a radial step.
An industrial application, comprising:
- an output unit;
- a drive unit;
- and
- a coupling designed to connect the drive unit to the output unit, said coupling comprising a first coupling portion designed for connection to a drive shaft of the drive unit, a second coupling portion connected to the first coupling portion for transmitting a drive torque and designed for connection to an output shaft of the output unit, and a bush accommodated in a through-hole of an axial hub portion of at least one of the first and second coupling portions and made of an electrically non-conductive high-performance plastics material, for receiving the drive shaft or the output shaft associated with the at least one of the first and second coupling portions, wherein the through-hole has an internal circumference formed with a radial step.
