Abstract
The utility model discloses a limit dust-proof structure of an inner gear ring of a one-way clutch, which comprises a limit retaining ring, a driving gear, a spring, a one-way clutch assembly, a planet shaft, an opening retaining ring, a planet wheel, an inner gear ring and a bearing. The driving gear is arranged at the front end of the one-way clutch and blocked through the limit retaining ring. The spring is arranged between the driving gear and the one-way clutch, one end of the planet shaft extends into the one-way clutch assembly and located through the opening retaining ring, the other end of the planet shaft extends into a big hole of the inner gear ring to be fixedly connected with the planet wheel, a blocking edge is arranged on an outer end face of a small hole of the inner gear ring, and the bearing is arranged in the small hole of the inner gear ring and blocked and limited through the blocking edge. Due to the fact that the blocking edge is arranged on the outer side of the bearing, the bearing can be prevented from string-moving axially during work, and outer dust can also be prevented from entering the inner gear ring from matching gaps on two sides of the bearing. The limit dust-proof structure has the advantages of being reliable in work, long in service life and the like.
Description
Technical field:
The utility model relates to the spacing dustproof construction of ring gear with the matching used one-way element of starter motor field, particularly a kind of one-way element.
Background technique:
At present, the ring gear of one-way element is when being rotatably assorted with planet axis, and its fitted bearing is directly installed in the aperture of ring gear, and the outside does not have backstop.The shortcoming of this structure is: in 1, using, axial motion takes place in bearing easily, causes occurring cooperating not firm or obscission, thereby has influenced the reliability of working; 2, external dust gets in the ring gear from the matching gap of bearing and planet axis and ring gear aperture easily; Can influence the matching relationship of ring gear and planet axis and planet wheel on the one hand; Also can quicken the wearing and tearing of ring gear, planet axis and planet wheel on the other hand, influence its working life.
The model utility content:
The goal of the invention of the utility model is to overcome the deficiency of above-mentioned existing technology, provides a kind of and prevents the bearing axial motion, and avoid external dust to get into the spacing dustproof construction of ring gear of the one-way element of ring gear.
For realizing the foregoing invention purpose, the utility model has adopted following technological scheme:
The spacing dustproof construction of a kind of ring gear of one-way element; Comprise spacing back-up ring, actuation gear, spring, one-way element assembly, planet axis, split washer, planet wheel, ring gear and bearing; Wherein, actuation gear is installed in one-way element assembly front end and by spacing back-up ring backstop, spring is located between actuation gear and the one-way element assembly; Planet axis one end stretches in the one-way element assembly and by split washer and locatees; The other end stretches in the macropore of ring gear affixed with planet wheel, and the outside end face of the aperture of said ring gear is provided with a stop edge, and said Bearing Installation is in the aperture of ring gear and spacing by this stop edge backstop.
Said stop edge and planet axis Spielpassung, said bearing and planet axis interference fit, said bearing and stop edge face contact matching.
The utility model has following advantage with respect to existing technology:
Because the arranged outside at bearing has stop edge; Therefore can prevent effectively that bearing from axial motion taking place at work on the one hand; Avoid occurring cooperating not firm or obscission; Guarantee the reliability of work, can prevent also that on the other hand external dust from entering into ring gear from the matching gap of bearing both sides, and guarantee matching relationship and working life thereof of ring gear and planet axis and planet wheel etc.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1, the spacing dustproof construction of ring gear of a kind of one-way element that provides according to the utility model comprises spacing back-up ring 1, actuation gear 2, spring 3, one-way element assembly 4, planet axis 5, split washer 6, planet wheel 7, ring gear 8 and bearing 9.Wherein, Actuation gear 2 is installed in one-way element assembly 4 front ends and by spacing back-up ring 1 backstop; Spring 3 is located between actuation gear 2 and the one-way element assembly 4, and planet axis 5 one ends stretch in the one-way element assembly 4 and by split washer 6 location, and the other end stretches in the macropore 81 of ring gear 8 affixed with planet wheel 7.The outside end face of the aperture 82 of ring gear 8 is provided with a stop edge 10, and bearing 9 is installed in the aperture 82 of ring gear 8 and is spacing by these stop edge 10 backstops.Stop edge 10 and planet axis 5 Spielpassung, bearing 9 and planet axis 5 interference fit, bearing 9 and 10 contact matching of stop edge.
