Abstract
A tensioning mechanism for tensioning a pre-loaded spring of a spring-loaded accumulator drive. The tensioning mechanism includes a tensioning wheel coupled to the pre-loaded spring, an intermediate shaft coupled to the tensioning wheel, an idler gear that can be driven by a clamping motor, a freewheel coupled to the idler gear, a locking mechanism for detachably locking the tensioning wheel in a tensioned state of the pre-loaded spring, and a dog clutch configured to couple the freewheel to the intermediate shaft in order to tension the pre-loaded spring and to uncouple same from the intermediate shaft in the tensioned state of the pre-loaded spring.

A tensioning mechanism for tensioning a pre-loaded spring of a spring-loaded accumulator drive, the tensioning mechanism comprising:
- a tensioning wheel coupled to the pre-loaded spring;
- an intermediate shaft coupled to said tensioning wheel;
- an intermediate gear to be driven by a tensioning motor;
- a freewheel coupled to said intermediate gear;
- a locking mechanism for releasably locking said tensioning wheel when the pre-loaded spring is in a tensioned state;
- and
- a dog clutch configured to couple said freewheel to said intermediate shaft in order to tension the pre-loaded spring, and to decouple said freewheel from said intermediate shaft when the pre-loaded spring is in the tensioned state.
A spring-loaded accumulator drive, comprising a tensioning mechanism according to claim.
