Abstract
The utility model discloses a bearing and press plate connection device which comprises a bearing (1) and a press plate (2). The press plate (2) is arranged on the outer ring of the bearing (1) through an assembling hole in a pressed mode. A ring of annular bosses (2a) are integrally formed on the inner wall of the assembling hole of the press plate (2). The annular bosses (2a) are embedded in a ring groove (1a) formed in the outer wall of the outer ring of the bearing (1). The bearing and press plate connection device is simple in structure, easy to machine and manufacture, capable of achieving assembling through one-time press fitting, convenient to assemble and operate, high in efficiency, good in connection reliability and capable of greatly reducing production cost.
Description
Technical field
The utility model relates to the linkage structure between a kind of gearbox inner bearing and pressing plate.
Background technique
Transmission shaft in gearbox supports mutually by bearing and casing, and bearing is generally positioned on casing by pressing plate.The Placement of described bearing and pressing plate routine, is that a jump ring in irregular shape is set between bearing and pressing plate, and this jump ring is set in the outer ring of bearing, and the outer wall of jump ring is provided with three convex closures, and each convex closure snaps in the corresponding pit arranging of pressing plate inwall.The deficiency of above structure is:
1) jump ring out-of-shape, and on jump ring, there are three complex-shaped convex closures, processing and fabricating difficulty on the one hand, on the other hand, the bulge quantity of convex closure must be controlled strictly, and bulge quantity is too much, can increase the difficulty that jump ring and pressing plate are installed, bulge quantity is very few, and the reliability that pressing plate is installed is poor, has the risk coming off.
2) inwall of pressing plate has three complex-shaped pits, and processing technology complexity can increase cost of production.
3) assembly process between pressing plate and bearing is many, and assembly manipulation is comparatively loaded down with trivial details, and packaging efficiency is low.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of bearing and pressing plate connection set that is easy to assembling and good reliability.
The technical solution of the utility model is as follows: a kind of bearing and pressing plate connection set, comprise bearing (1) and pressing plate (2), it is characterized in that: described pressing plate (2) press-fits on the outer ring of bearing (1) by pilot hole, on the inwall of pressing plate (2) pilot hole, be formed with a circle annular boss (2a), this annular boss (2a) embeds in the annular groove (1a) of offering on the outer ring outer wall of bearing (1).
The utility model has been cancelled the jump ring in conventional construction, adopts the annular boss on pressing plate to coordinate with the annular groove clamping of bearing outer ring, and still less, and the processing technology of annular boss and annular groove is simple, effectively reduces cost of production for one side component; On the other hand, by once press-fiting the assembling that can realize pressing plate and bearing, assembly process is few, and fitting operation is simple, can greatly improve efficiency of assembling.After being seated, be connected reliably between pressing plate and bearing, annular boss plays axial limiting, to prevent that pressing plate from coming off from bearing; Meanwhile, pressing plate relatively bearing rotates in a circumferential direction, so that the mounting hole contraposition on pressing plate and gear box.
Described pressing plate (2) is made by hot rolling steel plate, and the outer ring of bearing (1) is made by Bearing Steel.The intensity of pressing plate is high compared with intensity low and bearing outer ring, press-fits like this assembling easier; Pressing plate has good toughness and ductility, can not be damaged press-fiting in process.
Outside described bearing (1), the end of ring outer wall is provided with the guiding conical surface (1b).The guiding conical surface plays guiding on the one hand, so that pressing plate press-fits; On the other hand, the guiding conical surface can reduce the resistance that press-fits of pressing plate, makes to press-fit process faster.
As preferably, the both sides of described annular groove (1a) notch are all rounded down.
In order further to reduce to press-fit resistance, the aperture that described pressing plate (2) pilot hole packs direction into is tubaeform uncovered structure.
Beneficial effect: the utility model is simple in structure, processing and fabricating is easy, by once press-fiting, can realize assembling, and assembly manipulation is convenient, efficiency is high, the good reliability not only connecting, and can greatly reduce production costs.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1.
Fig. 3 is the B portion enlarged view of Fig. 2.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model consists of bearing 1 and pressing plate 2.Wherein, the outer ring of bearing 1 is made by Bearing Steel, on the outer wall of bearing 1 outer ring, is formed with step surface, has annular groove 1a on this step surface.The both sides of described annular groove 1a notch are all rounded down, and are provided with guiding conical surface 1b in the end of described bearing 1 outer ring outer wall.Described pressing plate 2 is triangular planar plate structure, and is made by hot rolling steel plate.At the middle part of pressing plate 2, have circular pilot hole, the aperture that these pressing plate 2 pilot holes pack direction into is tubaeform uncovered structure, and on the inwall of pilot hole, be formed with a circle annular boss 2a, the circumferential surface of annular boss 2a and pack between the end face of direction and pass through arc transition.Described pressing plate 2 press-fits on the outer ring of bearing 1 by pilot hole, and the annular boss 2a on pressing plate embeds in the annular groove 1a offering on the outer ring outer wall of bearing 1.Under the effect of annular boss 2a, pressing plate 2 is realized the axial limiting with bearing 1, and pressing plate 2 can rotate in a circumferential direction with respect to bearing 1.
Although below by reference to the accompanying drawings preferred embodiment of the present utility model is described; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite without prejudice to the utility model aim and claim; can make like multiple types and representing; as change shape or the material of pressing plate; or change the type of bearing etc., within such conversion all falls into protection domain of the present utility model.
