Abstract
The utility model relates to a motor end cover, which comprises a end cover end surface part (1), a plurality of installation legs (10) with an installation hole (4), and a bearing chamber (11), wherein, the cross section of the end cover end surface part (1) is in an I shape. The cross section of the end cover end surface part (1) is in an I shape, so that less materials are adopted to obtain the higher structural strength; the average thickness of the end cover is 2 mm, thereby reducing the consumption of the material, and having easy manufacturing and low cost.
Description
Technical field:
The utility model relates to a kind of electric motor end cap, belongs to the renovation technique of electric motor end cap.
Background technology:
At present, electric motor end cap, its end face part generally are the planes, even its intensity is strengthened in irregular variation, but because consistency of thickness everywhere, and do not have corresponding structure to strengthen its intensity, adopt relatively thick usually, consumptive material is many, thereby causes the manufacturing cost height, and weight is heavier; During assembling, consider the concentricity of stator and electric motor end cap, efficiency of assembling is lower; In addition, the bonding strength between end face part and the bearing chamber is not enough, influences the working life of bearing chamber; Do not reserve inspection opening, make after the motor assembling, be difficult to find that mistake is adorned and the situation of neglected loading.
Summary of the invention:
The purpose of this utility model is to provide a kind of electric motor end cap, and it adopts small wall thickness in proof strength, and consumptive material is few, easy to manufacture, cost is low.
The utility model is achieved through the following technical solutions: a kind of electric motor end cap, comprise the installation foot and the bearing chamber of end cap end face part, several band installing holes, and the cross section of end cap end face part becomes " worker " font.The cross section of end cap end face part becomes I shape, adopts minimum material and obtains the highest structural strength, and the end cap average wall thickness is 2mm, and consumptive material is few, easy to manufacture, cost is low.
The fitting surface of above-mentioned installation foot is provided with the concentric circles arc boss that several and stator core cylindrical match.Fitting surface is provided with the isocentric circular arc boss and cooperates with the motor stator core cylindrical, better guarantees the depth of parallelism and the concentricity of motor assembling back stator, the efficiency of assembling height.
The fitting surface of above-mentioned installation foot is provided with the empty avoiding structure, the empty avoiding structure comprise be arranged on the shoulder hole that is formed at the installing hole peristome on the fitting surface and with the inspection opening of shoulder hole radial communication.Fitting surface empty avoiding 60% makes installation foot processing change easily, be out of shape little, the precision height, whether whether the convenient motor of checking of inspection opening is adorned by mistake, the neglected loading part.
Be connected by a plurality of fan-shaped reinforcements between above-mentioned bearing chamber and the end cap end face part, fan-shaped reinforcement evenly distributes along the end cap end face part.The cross sectional shape of fan-shaped reinforcement is " worker " font.End cap is provided with a plurality of fan-shaped reinforcements, and the outside is I-shaped wide, and the both sides muscle is short, and inboard I-shaped narrow, both sides muscle height makes it adopt minimum material, minimum space, obtains maximum intensity, guarantees the working life of bearing chamber.
The cross section of above-mentioned installation foot is " U " type.The cross section of installation foot adopts U type structure, adopting less material simultaneously, guarantees the end cap installation strength, guarantees the screw assembling smoothly, and assembly process process is good.
Above-mentioned bearing chamber is provided with support foot.Bearing chamber is provided with support foot, guarantees that end cap is being in when arbitrarily angled, bearing and rotating shaft stressed evenly, better guarantee concentricity.
Described support foot is five.
