Embodiment
Core of the present utility model is to disclose a kind of bearing position structure, solves the problem of bearing play adjustment and the change of running post gap.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 2, the structural representation of the bearing position structure that Fig. 2 provides for the utility model embodiment.
The bearing position structure that the utility model embodiment provides, its core improvement is, comprises casing 23, locknut 22 and end cap 25;
The inner peripheral wall of casing 23 has the first inner peripheral surface 231 that the outer circumferential face for same bearing 21 coordinates, the inner peripheral wall of casing 23 is the second inner peripheral surface 232 away from the outer end portion of the first inner peripheral surface, and the part on the inner peripheral wall of casing 23 between the first inner peripheral surface 231 and the second inner peripheral surface 232 is provided with internal thread; In order to the normal mounting of locknut 22, on the inner peripheral wall of casing 23, the internal diameter size of internal thread should be not more than the internal diameter size of its second inner peripheral surface 232; It should be noted that, in view of bearing 21 is arranged in the hole of casing 23, the opening end in this hole finally installs end cap 25, and therefore the outer end of casing 23 inner peripheral wall refers to the opening end of above described holes;
The outer circle wall of locknut 22 is provided with the outside thread for same screw-internal thread fit, the both sides end face of locknut 22 is the plane perpendicular to its axis, its inner side end is used for offseting with bearing 21 end face outside, and to play the effect of axially locating to it, its structure can with reference to shown in Fig. 2;
The outer circle wall of end cap 25 has the first outer peripheral surface, the outside dimension of the first outer peripheral surface and the internal diameter size interference fit of the second inner peripheral surface 232, and the inner side end of end cap 25 is the plane offseted for the end face outside of same locknut 22, perpendicular to it axially; Be understandable that, the end face that end cap 25 exposes after installing is its end face outside, and relative opposite side end face is its inner side end, and the end face outside of locknut 22 in like manner.
As can be seen from above-mentioned technological scheme, the bearing position structure that the utility model embodiment provides, during installation, bearing is by screwing in or screw out locknut adjusting play, bearing accurate positioning; Bearing location locknut has auto-lock function, and speed reducer vibrations bearing can not axially be subjected to displacement, and extends the working life of bearing.
