Abstract
The utility model discloses the front end cap of a motor, which comprises an end cap body and a bearing pedestal. The edge of the end cap body is provided with a fixing lug and the fixing lug is provided with a fixing hole. The bearing pedestal is fixedly connected with the end cap body through at least three reinforcing ribs. A cavity is reserved between the inner wall and the outer wall of the bearing pedestal. The bearing pedestal is provided with a liquid inlet and a liquid outlet respectively. The liquid inlet and the liquid outlet are communicated with the cavity. According to the technical scheme of the utility model, the bearing pedestal is fixed onto the front end cap through the reinforcing ribs, thus is good in stability and is prevented from vibrating even when the motor is rotating at a high speed. Since the cavity reserved between the inner wall and the outer wall of the bearing pedestal is provided with the liquid inlet and the liquid outlet, the rotating shaft of the motor can be cooled through a cooling medium led into the cavity. Therefore, the cooling effect of the rotating shaft is good and the long-time running of the motor is ensured.
Description
Technical field
The utility model relates to a kind of motor component, especially the front end housing of motor.
Background technology
Motor is as a kind of common apparatus, be widely used in the industrial industry-by-industry, the motor in use quality of heat dispersion has directly determined useful life of motor, motor main body of the prior art places in the shell, owing to will consider driveability and the heat dispersion of motor, it all is installation shaft bearing on front end housing, electric machine main shaft is installed in the bearing pedestal by bearing, and on front end housing and rear end cap, offer louvre respectively, but the heat radiation of this form is often thorough inadequately, because heat mainly concentrates between bearing and the main shaft, if offer too much louvre at end cap, can cause the stability decreases of motor again, vibrations are bigger when motor rotates at a high speed.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the motor front end housing of a kind of stability height, perfect heat-dissipating is provided.
For achieving the above object, the technical solution of the utility model is:
A kind of motor front end housing, comprise the end cap main body, bearing pedestal, the edge of described end cap main body arranges fixedly ear, fixedly offer fixing hole on the ear, described bearing pedestal is fixedlyed connected with the end cap main body by at least three reinforcements, is provided with cavity between the inner and outer wall of described bearing pedestal, and offer inlet and liquid outlet on the bearing pedestal respectively, described inlet and liquid outlet are communicated with cavity.
As the further setting of such scheme, the material of described reinforcement is steel alloy, and the two ends of reinforcement are welded on respectively on bearing pedestal and the end cap main body.
The beneficial effects of the utility model are: by reinforcement bearing pedestal is fixed on the front end housing, stability is good, can not produce vibrations because motor rotates at a high speed, be provided with cavity between the bearing pedestal inner and outer wall, and be provided with inlet and liquid outlet, come machine shaft is cooled off by feed coolant in cavity, good cooling results has guaranteed that motor can work for a long time.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model.
Among the figure: end cap main body 1, fixedly ear 2, fixing hole 21, bearing pedestal 3, inlet 31, liquid outlet 32, cavity 33, reinforcement 4.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1, a kind of motor front end housing, comprise end cap main body 1, bearing pedestal 3, the edge of described end cap main body 1 arrange fixedly ear 2, fixedly offer fixing hole 21 on the ear 2, described bearing pedestal 3 is fixedlyed connected with end cap main body 1 by at least three reinforcements 4, be provided with cavity 33 between the inner and outer wall of described bearing pedestal 3, and offer inlet 31 and liquid outlet 32 on the bearing pedestal 3 respectively, described inlet 31 and liquid outlet 32 are communicated with cavity 33.
The material of described reinforcement 4 is steel alloy, and the two ends of reinforcement 4 are welded on respectively on bearing pedestal 3 and the end cap main body 1.
The utility model is fixed on bearing pedestal 3 on the front end housing main body 1 by reinforcement 4, stability is good, can not produce vibrations because motor rotates at a high speed, be provided with cavity 33 between the inner and outer wall of bearing pedestal 3, inlet 31 and liquid outlet 32 are communicated with cavity 33, feed coolant during machine operation in cavity 33, come bearing and rotating shaft are cooled off by the mode of coolant circulation, good heat dissipation effect has guaranteed that motor can work for a long time.
