Embodiment
Referring to figs. 1 through Fig. 3, the embodiment of a kind of one-way element assembly of the utility model is described further.
A kind of one-way element assembly, comprise splined shaft 1 and hollow shaft 2, described hollow shaft 2 is sleeved on described splined shaft 1, described splined shaft 1 one end is provided with actuation gear 3, on described hollow shaft 2, be engaged with star-wheel 4, on described star-wheel 4, be circumferentially evenly equipped with several one-way clutch grooves 5, in described one-way clutch groove 5, be provided with roller 6 and be used to this roller 6 that the flat spring 7 of reseting elasticity is provided, between described roller 6 and described flat spring 7, be provided with support rod 8, described support rod 8 one end and described roller 6 are inconsistent, and the other end is embedded on flat spring 7.
By the internal structure of star-wheel 4 is done to further improvement, increase a support rod 8 and this support rod 8 one end and described roller 6 inconsistent, the other end is embedded on flat spring 7, the design of support rod 8 directly replaces traditional one-way element assembly flat spring 7 and the direct conflict between roller 6, in the process that (it should be noted that: the material that this support rod 8 is smooth abrasion-proof forms) circumferentially rolls at roller 6, flat spring 7 not being produced to any impact has herein avoided the distortion of flat spring 7 so that had lost efficacy, the working life of having guaranteed one-way element assembly.
