The purpose of the utility model can realize through following technical proposal: a kind of bearing mounting structure of automotive transmission; Comprise bearing support and bearing; It is characterized in that; Described bearing is arranged in the bearing support, is provided with the position structure that can prevent that bearing outer ring from circumferentially rotating between described bearing and the bearing support.
Bearing in the bearing mounting structure of this automotive transmission is arranged in the bearing support; Be used for assembling rotating shaft; Position structure between bearing and bearing support can prevent effectively that bearing outer ring from circumferentially rotating; Improve the working life of bearing, speed changer can be used normally, and then improve drive safety.
In the bearing mounting structure of above-mentioned automotive transmission; Described position structure comprises breach and the locating stud that is opened on the bearing outer ring; Described locating stud one end is fixed in the bearing support; The other end of locating stud has a bending head, and the bending head of described locating stud is resisted against the indentation, there of bearing outer ring.Locating stud one end is fixed in the bearing support, and the bending head of the locating stud the other end is resisted against on the breach of bearing outer ring, and both have very big surface friction drag, can prevent effectively that bearing outer ring from rotating.Breach on the bearing outer ring is smaller, avoids influencing bearing intensity.
As other a kind of situation, in the bearing mounting structure of above-mentioned automotive transmission, described position structure is a positioning rod, and described positioning rod one end is welded on the bearing support, and the other end is welded on the bearing outer ring.Through positioning rod bearing outer ring and bearing support are welded together, bearing outer ring can't be rotated.
In the bearing mounting structure of above-mentioned automotive transmission, offer positioning hole in the described bearing support, above-mentioned locating stud is fixed in this positioning hole through the mode of interference fit.Locating stud is fixed on the bearing support easy for installation, good positioning effect through such mode.
In the bearing mounting structure of above-mentioned automotive transmission, offer mounting hole in the described bearing support, described bearing is arranged in the mounting hole of bearing support through the mode of interference fit.Bearing is arranged in the mounting hole of bearing support through the mode of interference fit, and combines locating stud, can bearing outer ring can not be rotated dual assurance.
In the bearing mounting structure of above-mentioned automotive transmission, described locating stud adopts stainless steel material to process.The locating stud long service life that stainless steel material is processed can not got rusty.
Compared with prior art; The bearing mounting structure of this automotive transmission is resisted against on the breach of bearing outer ring the bending head of locating stud through a locating stud is inserted between bearing and the bearing support, can prevent effectively that bearing outer ring from rotating; Improve the working life of bearing, reduce user cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, bearing support; 2, bearing; 21, breach; 3, locating stud; 31, bending head.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
Embodiment one:
As shown in Figure 1, a kind of bearing mounting structure of automotive transmission comprises bearing support 1 and bearing 2, in bearing support 1, is provided with mounting hole, and bearing 2 is fixed in this mounting hole through being full of the mode that cooperates.
Between bearing 2 and bearing support 1, be provided with the position structure that can prevent that bearing 2 outer rings from circumferentially rotating; In present embodiment one; Position structure comprises the breach 21 and locating stud 3 that is opened on bearing 2 outer rings, in bearing support 1, offers positioning hole, and locating stud 3 one ends are fixed in this positioning hole through the mode of interference fit; The other end of locating stud 3 has a bending head 31, and the bending head 31 of locating stud 3 is resisted against breach 21 places of bearing 2 outer rings.Concrete, breach 21 forms through cutting instrument cutting, and the exterior edge face of breach 21 is the plane, and in order to ensure the intensity of bearing 2, the otch of being cut is less.Locating stud 3 one ends are fixed in the bearing support 1, and the bending head 31 of locating stud 3 the other ends is resisted against on the plane of breach 21, and both have very big surface friction drag, can effectively prevent the rotation of bearing 2 outer rings.
