Abstract
The invention discloses a connecting structure for a motor cover and a bearing. The connecting structure comprises an end cover (3) and the bearing (2); the middle of the end cover (3) is provided with a bearing block (4) used for mounting the bearing (2); the inner wall of the bearing block (4) is provided with a concave locating slot (41) used for the bearing (2) to embed and locate; the outer ring of the bearing (2) is radially provided with a boss (21) convexly; when the bearing (2) is embedded in the bearing block (4), the boss (21) can prevent the bearing (2) from moving relative to the bearing block (4) and make the bearing (2) clamped in the locating slot (41). The connecting structure has the advantages that the inner wall of the bearing block of the end cover of a motor is provided with the concave locating slot, and the outer ring of the bearing is provided with the boss matched with the locating slot, so that the bearing can be stably embedded in the bearing block, the relative movement of the bearing and the bearing block is effectively prevented, the abrasion caused by the relative movement between the bearing and the bearing block is eliminated, the stability of relative rotation of a core and a body of the motor is ensured, and the service life of the motor is effectively prolonged.
Description
Technical field
The invention belongs to motor production technical field, the syndeton of especially a kind of motor cover and bearing.
Background technology
In the prior art, motor generally comprises housing, rotating shaft and motor cover, is provided with the bearing that makes rotating shaft swivel bearing in motor cover, bearing is embedded in the bearing pedestal at end cap middle part, its outer ring and bearing pedestal inwall fit tightly, and when rotating shaft is rotated, the inner ring of bearing also rotates thereupon.Because bearing is to be embedded in bearing pedestal, there is no special detent mechanism, therefore service time of a specified duration can be because reasons such as wearing and tearing, between the outer ring of bearing and bearing pedestal, can slide, can not well interfix, this situation not only can make the operational effect of motor poor, and noise increase, easily stuck, also can lower the useful life of motor, so its structure needs to improve.
Summary of the invention
Technical problem to be solved by this invention is for the above-mentioned state of the art, to provide a kind of reasonable in design, simple in structure and can effectively prevent bearing pedestal movable syndeton relative to bearing.
The present invention solves the problems of the technologies described above adopted technical scheme: the syndeton of a kind of motor cover and bearing, comprise end cap and bearing, the middle part of described end cap is provided with for bearings mounted bearing pedestal, it is characterized in that: described bearing pedestal inwall is provided with the location notch for bearing embedding location of an indent, on the outer ring of bearing, radial convex is provided with projection, when described bearing is when being embedded in bearing pedestal, described projection can prevent that bearing is relative with bearing pedestal movable and be snapped in location notch.
As improvement, the breach that described location notch is rectangle.
As improvement, described projection is cylindrical, bar shaped or hemisphere.
As improvement, described bearing pedestal is sleeve-shaped, is provided with the circular chamber of mating with the outer ring size of bearing in described bearing pedestal, and described bearing is embedded in circular chamber, and described location notch is opened on the inwall of circular chamber.
Improve again, on described end cap, be provided with the axis hole stretching out for the end of rotating shaft with the coaxial bearing heart.
Further improve, described bearing pedestal and end cap are integrated the overall structure being made.
Compared with prior art, the invention has the advantages that: the location notch that is provided with an indent at the inwall of the bearing pedestal of electric motor end cap, the outer ring of bearing is provided with the projection coordinating with location notch, this design can make bearing stably be embedded in bearing pedestal, thereby effectively prevented the relative activity of bearing with bearing pedestal, eliminated because wear phenomenon appears in this relative activity of bearing and bearing pedestal, guaranteed in motor movement and body stability in relative rotation, thereby effectively extended the useful life of motor, also have, because having eliminated the relatively movable noise that reduced, guaranteed the operation of the normal work of motor.

Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
As shown in Figures 1 to 5, the motor cover of the present embodiment and the syndeton of bearing, comprise end cap 3 and bearing 2, the integral middle of end cap 3 forms for the bearing pedestal 4 of bearing 2 is installed, bearing pedestal 4 inwalls are provided with the location notch 41 for bearing 2 embedding location of an indent, on the outer ring of bearing 2, radial convex is provided with projection 21, when described bearing 2 is when being embedded in bearing pedestal 4, described projection 21 can prevent bearing 2 activity relative to bearing pedestal 4 and be snapped in location notch 41, the breach that location notch 41 is rectangle, described projection 21 is cylindrical, bar shaped or hemisphere; Described bearing pedestal 4 is sleeve-shaped, is provided with the circular chamber of mating with the outer ring size of bearing 2 in described bearing pedestal 4, and described bearing 2 is embedded in circular chamber, and described location notch 41 is opened on the inwall of circular chamber; On described end cap 3, be provided with the axis hole 31 stretching out for the end of rotating shaft 5 with bearing 2 concentrics, the outward flange of end cap 3 is respectively equipped with the installing hole 32 coordinating with the end face of electric machine casing 1, end cap 3 is the involutory two ends up and down that are arranged on electric machine casing 1 respectively, by screw and electric machine casing 1, are connected and fixed.
Bearing 2 just can stably be embedded in bearing pedestal 4 like this, thereby effectively prevented the relative activity of bearing 2 with bearing pedestal 4, eliminated because wear phenomenon appears in relative activity between bearing 2 and bearing pedestal 4, guaranteed in motor movement and body stability in relative rotation, extended significantly the useful life of motor, also have, because having eliminated activity relatively, reduced noise, guaranteed normal work and the operation of motor.
