| 摘要 |
The present invention concerns a device for preloading of a spring (1) which has a first end rigidly attached to a first support means (5) and a second end rigidly attached to a second support means (7), at least one of said support means being rotatable around an axis of rotation relative to the other support means, thereby tensioning or detensioning said spring, and where the spring and both support means are located in a tube (15). The device is characterized by comprising a control means (10) connected to one of said support means, which is rotatable, said control means protruding to the outside of the tube (15) and usable to rotate said rotatable support means, making it possible to preload the spring from the outside of the tube. The invention also concerns a correponding method and a reeling device including said preloading device. |
