Description
Technical Field
The utility model relates to a motor end cover field specifically is a tensile end cover structure.
Background
The motor end cover is one of main accessories on the motor, and the main functions of the motor end cover are to install a bearing and a rotor, dissipate heat, fill lubricating oil and the like, so that the quality of the motor is directly influenced. The traditional stretching end cover is formed by gradually stretching through a plurality of processes, and the cylindrical surface of the bearing chamber and the inner cylindrical surface of the end cover are formed by stretching through a plurality of processes, so that the concentricity is poor. The concentricity of the inner cylindrical surface of the end cover and the cylindrical surface of the bearing chamber is low, and the electromagnetic noise of the motor is high. Meanwhile, the air gap of the motor with the traditional end cover is large, the motor efficiency is low, and the temperature rise of the motor is fast.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a tensile end cover structure to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a tensile end cover structure, includes end cover body and bearing chamber apron, end cover body bottom is provided with bearing chamber apron groove, and bearing chamber apron inslot side is equipped with the bearing room, bearing chamber apron groove passes through rivet fixed connection with bearing chamber apron, and the centre of a circle department of bearing chamber apron is provided with the shaft hole.
Preferably, the terminal surface outward flange of end cover body is provided with counterpoint groove, U type groove and mounting hole, and the counterpoint groove is provided with 1, and the counterpoint groove is the circular arc groove, and U type groove is provided with 2, and the mounting hole is the circular port, and the mounting hole is provided with two kind at least apertures.
Preferably, the bearing chamber cover plate groove is an inward concave groove body, and the end cover body, the bearing chamber cover plate groove and the bearing chamber are of an integrally formed structure.
Preferably, the number of the rivets is at least 4, and the rivets are riveted on the edge of the bearing chamber cover plate at equal intervals.
Compared with the prior art, the beneficial effects of the utility model are that: the scheme of the utility model improves the concentricity of the inner cylindrical surface of the motor end cover and the cylindrical surface of the bearing chamber; the electromagnetic noise of the motor is reduced; the motor efficiency can be improved and the motor temperature rise can be reduced by reducing the motor air gap.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below. The embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative work, all belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a tensile end cover structure, includes end cover body 1 and bearing chamber apron 7, and 1 bottoms of end cover body is provided with bearing chamber apron groove 5, and 5 inboards in bearing chamber apron groove are equipped with bearing chamber 6, and bearing chamber apron groove 5 passes through rivet 8 fixed connection with bearing chamber apron 7, and the centre of a circle department of bearing chamber apron 7 is provided with shaft hole 9.
The terminal surface outward flange of end cover body 1 is provided with counterpoint groove 2, U type groove 3 and mounting hole 4, and counterpoint groove 2 is provided with 1, and counterpoint groove 2 is the circular arc groove, and U type groove 3 is provided with 2, and mounting hole 4 is the circular port, and mounting hole 4 is provided with two kind at least apertures.
The bearing chamber cover plate groove 5 is an inward concave groove body, and the end cover body 1, the bearing chamber cover plate groove 5 and the bearing chamber 6 are of an integrally formed structure.
At least 4 rivets 8 are arranged, and the rivets 8 are riveted on the edge of the bearing chamber cover plate 7 at equal intervals.
The end face of the end cover and the inner cylindrical surface of the end cover can be used as reference surfaces to finish machining of the cylindrical surface of the bearing chamber, and then the bearing chamber cover plate is riveted on the outer end face of the bearing chamber of the end cover. Therefore, the concentricity of the inner cylindrical surface of the end cover and the cylindrical surface of the bearing chamber can be improved, and the electromagnetic noise of the motor is reduced. Meanwhile, the motor efficiency can be improved by reducing the motor air gap, and the temperature rise of the motor is reduced.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
