Abstract
The utility model discloses a spring-supported roller type one way clutch, comprising a gear shaft, a sliding seat, a cover plate assembly, a cover cap, a roller and a spring. The roller is arranged between the sliding seat and the gear shaft, and the spring leans against the roller. The spring-supported roller type one way clutch is characterized in that a spring bearing is also arranged between the roller and the spring. By adopting the spring-supported roller type one way clutch, the spring bearing is additionally arranged at the inner part of the clutch, thus avoiding the disadvantage of the direct contact between the spring and the roller, and prolonging the service life of the one way clutch; moreover, the structure of the spring bearing is simple and the spring bearing is convenient for being widely applied.
Description
Technical field
The utility model relates to a kind of roller-type one way clutch, relates in particular to a kind of spring-supported roller-type one way clutch that has.
Background technique
Present existing roller-type one way clutch is automobile-used, be widely used in the starter motor of marine engine and (please refer to Fig. 1, Fig. 1 a), this roller-type one way clutch mainly is by slide 1, roller 2, spring 3, gear shaft 4, cover plate assembly 5, cooperatively interacting between the cover cap 6 realized its one-way clutch function: when slide 1 relative gear shaft 4 clockwise directions rotate, under the elastic force effect of inertia and spring 3, roller 2 will be to the narrow place motion of the key groove on the slide 1, cause roller 2 by wedging, slide 1 like this, roller 2, gear shaft 4 threes rotary work together in aggregates, this moment, overrunning clutch was in locking state, the moment of torsion that motor produces can be outputed to the engine flywheel gear ring like this.If slide 1 relative gear shaft 4 rotation counterclockwise, roller 2 will be to the motion of the wedge shape angular width place on the slide 1, and slide relative appears in slide 1, roller 2, gear shaft 4 threes at this moment, can not form a body running, and one-way element is in slipping state.
Existing roller-type one way clutch directly contacts with spring 3 owing to roller 2.In surmounting process, there is slide relative and fast poor very big in roller 2 with spring 3, the two contacting part branch produces wearing and tearing, the metallic dust that grinding is got off mixes mutually with lubricant grease, cause the lubricating ability of lubricant grease to descend rapidly, and then causing gear shaft working surface, slide curved surface and roller surface wearing and tearing aggravation, grease is dried-up.Final overrunning clutch premature failure, starter motor can't proper functioning.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of spring-supported roller type one way device clutch that has, direct and the contacted defective of spring with the roller that overcomes existing roller-type one way clutch, prolong the working life of overrunning clutch, the working life of finally improving starter motor.
To achieve these goals, the utility model provides a kind of spring-supported roller-type one way clutch that has, comprise: gear shaft, slide, cover plate assembly, cover cap and be arranged on slide and gear shaft between roller and replace the spring of roller, it is characterized in that, also be provided with spring between described roller and the spring and support.
Above-mentioned have a spring-supported roller-type one way clutch, and wherein, described spring is supported and fixed on the end of described spring and is butted on described roller mutually.
Above-mentioned have a spring-supported roller-type one way clutch, and wherein, described spring-supported longitudinal section is a rectangle.
Above-mentioned have a spring-supported roller-type one way clutch, wherein, has at least one positioning boss on the described spring-supported outer surface.
Above-mentioned have a spring-supported roller-type one way clutch, wherein, has at least one positioning groove on the described spring-supported outer surface.
Above-mentioned have a spring-supported roller-type one way clutch, wherein, described spring support with described roller bearing surface be inner concave arc surface.
Above-mentioned have a spring-supported roller-type one way clutch, and wherein, described spring is supported for wear-resistant plastic spare.
Beneficial functional of the present utility model is: increased in roller-type one way clutch inside and avoided spring and the direct contacted defective of roller after spring supports, improved the working life of one-way element clutch, this spring cupport structure is simple simultaneously, is convenient to extensive use.
Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.

Embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and working principle are done concrete description:
In Fig. 2, Fig. 2 a, Fig. 3, specific embodiments shown in Figure 4, the utility model prompting is a kind of to have spring-supported roller-type one way clutch, and comprising: slide 1, roller 2, spring 3, gear shaft 4, cover plate assembly 5, cover cap 6, spring support 7.
Compare with existing roller-type one way clutch, it is characterized in that: increase is provided with a spring and supports 7 between roller 2 and the spring 3, spring 3 is installed in spring supports on 7, allow roller 2 directly support 7 and contact, so just solved roller 2 and spring 3 direct contacted defectives with spring.
As shown in Figure 4, the outer surface of spring support 7 is provided with positioning boss, and positioning boss can be set to a plurality of according to the physical dimension of spring, spring-supported a plurality of positioning boss is fastened on the end of spring respectively.
Shown in Fig. 5 and Fig. 6 a to Fig. 6 d, spring of the present utility model supports 7 and also has other a plurality of different embodiments, spring-supported longitudinal section can be designed to rectangle, can also will a plurality of grooves be set on the spring-supported outer surface, in a word, spring supports 7 ends that can be fastened on spring and gets final product, and does not exceed with said structure.
The corresponding to indent arc structure of outer surface with roller 2 is adopted on the surface that spring support 7 and roller 2 connect.
In order further to make the utility model reach better usability, spring supports 7 and adopts the plastic materials with good lubrication effect and wear-resisting property to make.
In the assembly process of reality, at first spring 3 is installed on the positioning boss of spring support 7, in the slide 1 of then their integral body being packed into, the interior concaved circular cambered surface of spring support 7 is contacted with the outer surface of roller 2.
