Embodiment
Be elaborated below in conjunction with the embodiment of accompanying drawing to the utility model.Should be understood that embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
As shown in the figure; A kind of embodiment according to the utility model; Syndeton between a kind of scrambler and the rotating mechanism is provided, and said scrambler comprises coder shaft 11 and scrambler body 12, and said rotating mechanism comprises revolving part 21 and fixture 22; Said coder shaft 11 is connected to said revolving part 21, and said scrambler body 12 is connected to said fixture 22.More specifically, said scrambler body 12 is connected to said fixture 22 through at least three springs 30, and the elastic acting force that applies of 30 pairs of said scrambler bodies 12 of these at least three springs said coder shaft 11 in the radial direction to make a concerted effort be zero.
In the utility model, coder shaft 11 can be connected on the revolving part 21 through any suitable means in the prior art.As a kind of typical embodiment, as shown in Figure 3, coder shaft 11 can be fixed on the said revolving part 21 through connector 50.Particularly, an end of connector 50 can insert and be fixed on the revolving part 21, and simultaneously, the other end of connector 50 can inserted and be fixed to coder shaft 11.
According to technique scheme, scrambler body 12 is connected to fixture 22 through at least three springs 30, and the elastic acting force that applies of 30 pairs of scrambler bodies 12 of these at least three springs coder shaft 11 in the radial direction to make a concerted effort be zero.Therefore, through the elastic acting force of these springs 30, make scrambler body 12 receive elastic restraint in the radial direction.In the scrambler course of work; Be that coder shaft 11 is in scrambler body 12 in the rotary course; If when the centre of gyration of the centre of gyration of coder shaft 11 and scrambler itself is inconsistent (consider the manufacturing accuracy and the installation accuracy of scrambler itself, objectively possibly reach in full accord hardly), spring 30 can cushion and absorb the vibrations of scrambler; Alleviate the adverse effect that these vibrations cause scrambler, thereby can prolong the serviceable life of scrambler.In addition, because spring 30 has buffering and absorb the effect of scrambler vibrations, therefore can suitably reduce in the installation process requirement, thereby can reduce installation cost the right alignment between coder shaft 11 and the revolving part 21.
For guarantee elastic acting force that 30 pairs of scrambler bodies 12 of all springs apply coder shaft 11 in the radial direction to make a concerted effort be zero, can adopt multiple means to realize.For example, spring 30 can adopt extension spring or compression spring, can some be extension spring also, and some are compression spring.In addition, all spring 30 preferred evenly distributions on the circumferential direction of coder shaft 11 are the center with coder shaft 11 promptly, in its circumferencial direction spaced at equal angles around, adopt this arrangement, simple in structure and easy realization.
As a kind of preferred exemplary embodiment, as shown in Figure 2, what the utility model adopted is three extension springs 30, and it evenly distributes in a circumferential direction, promptly is triangle star and distributes.The simple and stable of this arrangement structure, effect is best, and extension spring is fixing also convenient comparatively speaking.
In addition, as shown in Figure 4, three circumferential each other 120 degree at interval of spring 30; The pulling force size is equal to each other, and is respectively F1, F2, F3, and its radial component size is equal to each other; Be respectively F1a, F2a, F3a, resultant radial force is zero, and the axial thrust load size is equal to each other; Be respectively F1b, F2b, F3b, axially make a concerted effort to be F1b, F2b, F3b sum, direction is pointed to revolving part 21.Three spring 30 radial component sums are zero; Guaranteed that scrambler body 12 has self-centering characteristics, axial thrust load can be pressed in coder shaft 11 on the revolving part 21 greater than zero tightly; Make to be connected more firmly between coder shaft 11 and the revolving part 21 that scrambler work is more reliable.
Mounting structure in the face of spring is elaborated down.
Particularly; Extremely shown in Figure 3 like Fig. 1; A kind of preferred implementation according to the utility model can comprise mounting disc 40, and this mounting disc 40 has center pit 42 and is releasably attached on the fixture 22; One end of every spring 30 is fixed on the scrambler body 12, and the other end is fixed in the mounting disc 40.
More specifically, can have a plurality of stationary shaft 41 on the side surface of said mounting disc 40, have radial hole 44 on each stationary shaft 41, an end of every spring 30 remains in the radial hole 44 of corresponding stationary shaft 41.
Through mounting disc 40, mounting spring 30 and easy accessibility more easily.For example; In installation process; The radial hole 44 that can an end of spring 30 be passed on the stationary shaft 41 keeps, and then the mounting hole 43 that uses securing member such as bolt to pass in the mounting disc 40 is fixed to mounting disc 40 on the fixture 22, makes spring 30 have suitable pretightning force.Stationary shaft 41 can directly be arranged in the mounting disc 40 through welding or other modes.In addition, the center pit 42 in the mounting disc 40 can be used for dodging connector 50.
As a kind of embodiment simple in structure, three screws 13 can be set on the end face of scrambler body 12, an end of spring 30 is hung on the screw 13 get final product.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned embodiment; In the technical conceive scope of the utility model, can carry out multiple simple variant to the technical scheme of the utility model, these simple variant all belong to the protection domain of the utility model.
Need to prove in addition; Each concrete technical characterictic described in above-mentioned embodiment; Under reconcilable situation; Can make up through any suitable manner, for example a plurality of extension springs or compression spring evenly distribute on the circumferential direction of coder shaft, and a plurality of springs evenly distribute on the circumferential direction of coder shaft and axially make a concerted effort greater than zero or the like.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible array modes.
In addition, also can carry out combination in any between the various embodiment of the utility model, as long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model equally.
