Abstract
The utility model discloses an end cover structure of a motor. The end cover structure comprises an end cover and a bearing. A bearing pedestal is disposed on the center of the end cover. Grooves penetrating the bearing pedestal are also disposed in the end cover. Ventilation openings are disposed around the bearing pedestal. The grooves are arranged between every two adjacent ventilation openings. Hooks are connected with the ventilation openings. The bearing is installed in the bearing pedestal and is compacted by a bearing cap. The bearing cap is fixed on the end cover in a clamping connection manner through the hooks. Compared with a product in the prior art, the end cover structure uses the grooves which penetrate the bearing pedestal and which are disposed in the end cover. After the bearing is installed on the bearing pedestal, the grooves provide flow channels for heat generated by the bearing in order to prevent the heat from being accumulated in the bearing pedestal and the bearing. Finally, the heat is exhausted out of the ventilation openings around the bearing pedestal. The end cover structure has advantages of a strong heat-dissipating capability and a long service life. The bearing cap is fixed on the end cover through the hooks so that the structure of the end cover is simplified and the end cover structure is easy to install and repair.
Description
Technical field
The utility model relates to a kind of end cover mechanism of motor, belongs to the parts of motor.
Background technology
end cover mechanism is the important component part of motor, in prior art, generally offer the bearing pedestal of sealing on end cap, bearing pedestal is used for placing bearing, motor is when operation, bearing can send a large amount of heats, but the closing means due to bearing pedestal and bearing cap composition, heat is difficult to shed, therefore after end cap length service time, itself will be out of shape bearing pedestal or bearing, cause wearing and tearing, directly affect the performance and used life of product, existing end cover mechanism general employing on the installation method of bearing welded or the fixing mode that is spirally connected simultaneously, very loaded down with trivial details.
The utility model content
The purpose of this utility model be for above-mentioned the deficiencies in the prior art provide that a kind of thermal diffusivity is strong, long service life, electric motor end cap mechanism simple in structure.
For achieving the above object, the technical solution of the utility model is: a kind of end cover mechanism of motor, comprise end cap and bearing, the center of end cap offers bearing pedestal, also offers the groove of through-shaft bearing in described end cap, is provided with ventilating opening around bearing pedestal, described groove is between two adjacent ventilating openings, be connected with snap fit on ventilating opening, described bearing is arranged in bearing pedestal and by bearing cap and compresses, and described bearing cap connects and fixes by snap fit and end cap.
As the further setting of such scheme, be evenly distributed with the flexible feet of a plurality of perks on the inner ring of described bearing cap, described flexible feet is close on the outer wall of bearing.
As the further setting of such scheme, the edge of described ventilating opening is provided with bevelling.
The beneficial effects of the utility model are: compared with prior art, also offer the groove of through-shaft bearing in end cap, after bearing is installed to bearing pedestal, the heat that groove will give the bearing generation provides a flow channel, prevent that heat is collected in bearing pedestal and bearing, finally, heat is by discharging in the ventilating opening around bearing pedestal, make and the utlity model has the advantage strong, the life-span of dispelling the heat, the mode that bearing cap is fixed by snap fit and end cap, simplify end cap with regard to structure, made the utility model install and keep in repair very convenient.

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, Figure 2, Figure 3 shows, the utility model comprises end cap 1 and bearing 2, the center of end cap 1 offers bearing pedestal 3, also offer the groove 4 of through-shaft bearing 3 in described end cap 1, be provided with ventilating opening 5 around bearing pedestal 3, described groove 4 between two adjacent ventilating openings 5, is connected with snap fit 6 on ventilating opening 5, described bearing 2 is arranged in bearing pedestal 3 and by bearing cap 7 and compresses, and described bearing cap 7 connects and fixes by snap fit 6 and end cap 1.
Be evenly distributed with the flexible feet 8 of a plurality of perks on the inner ring of described bearing cap 7, described flexible feet 8 is close on the outer wall of bearing 2.
The edge of described ventilating opening 5 is provided with bevelling 9.
Operation principle of the present utility model is: the groove 4 that offers through-shaft bearing 3 in end cap 1, after bearing 2 is installed to bearing pedestal 3, the heat that groove 4 will give bearing 2 generations provides a flow channel, prevent that heat is collected in bearing pedestal 3 and bearing 2, be provided with ventilating opening 5 around bearing pedestal 3, heat enters into external environment condition by discharging motor in ventilating opening 5, has improved the motor radiating performance, thereby has extended useful life; Connect snap fit 6 on ventilating opening 5, bearing 2 is compressed by bearing cap 7, and bearing cap 7, by the fixing mode of snap fit 6 and end cap 1, has been simplified the structure of end cap 1, is easy to install and maintain; Be uniformly distributed the flexible feet 8 of a plurality of perks on the inner ring of bearing cap 7, motor is when operation, and rotor will produce axial vibration, flexible feet 8 gives bearing 2 mechanical dampings, prevent displacement, two 8 of adjacent flexible feets form gap simultaneously, are conducive to the heat radiation of bearing 2 and bearing chamber 3; The edge of ventilating opening 5 arranges bevelling 9, has strengthened the mechanical structure of end cap 1.
