Abstract
A detachable coupling on a rotary drive is provided with first and second coupling surfaces (14, 17) arranged opposite each other. The coupling parts can be assembled without observing a preferential position. The first coupling surface (14) has a plurality of needles (15), which are arranged in a matrix-like pattern and point away from the coupling surface (14). The second coupling surface (17) has a fabric layer (18) designed to receive the needles (15).
Claims15
A coupling for a rotary drive, comprising:
- a first coupling surface having a plurality of needles arranged in a distributed pattern, the needles pointing away from said first coupling surface;
- a second coupling surface arranged opposite said first coupling surface, said second coupling surface having a fabric layer for receiving said needles.
A process for providing a coupling, the process comprising the steps of:
- providing a breathing gas delivery unit of a respirator with a rotatable gas delivery element;
- providing a first coupling surface connected to the rotatable gas delivery element, the first coupling surface having one of a plurality of needles arranged in a distributed pattern, the needles pointing away from the first coupling surface and a fabric layer for receiving the needles;
- providing a drive element;
- providing a second coupling surface connected to the drive element, the second coupling surface having the other of the plurality of needles arranged in a distributed pattern, the needles pointing away from the first coupling surface and the fabric layer for receiving the needles;
- connecting the drive element to the rotatable gas delivery element via a connection between the first coupling surface and the second coupling surface with the fabric layer receiving the needles.
A rotary drive with detachable coupling, comprising:
- a drive part with a first coupling surface having one of a plurality of needles arranged in a distributed pattern, the needles pointing away from the first coupling surface and a fabric layer for receiving the needles;
- a driven part with a second coupling surface having the other of the plurality of needles arranged in a distributed pattern, the needles pointing away from the first coupling surface and the fabric layer for receiving the needles, whereby the drive part and the driven part can be connected without observing a preferential position.
