Abstract
The utility model relates to a motor flange end cover, which comprises a body including a bearing chamber, a large flange surface, an inner chamber and supporting ribs, wherein the large flange surface is arranged on the outer side of the body, the inner chamber is arranged in the inner middle of the body, the bearing chamber is arranged in the middle of the inner chamber, and the supporting ribs are arranged on the outer circumference of the body. When the motor flange end cover is mounted on a motor, air energy generated by a fan in the motor can directly cool the whole large flange surface, and high temperature of client equipment transferred to a bearing in the bearing chamber is decreased. Besides, the bearing in the bearing chamber is far away from a winding, so that heat influence generated by the winding is weakened. The outer wall of the bearing chamber is directly exposed in cooling air, and the air energy generated by the fan is blown to the outer wall of the bearing chamber, so that radiating conditions of the bearing are greatly improved, and radiating speed of the bearing is greatly increased. The radiating area of the bearing is greatly increased by means of radiating ribs added on the outer wall of the bearing chamber. The motor flange end cover is simple and practical in structure.
Description
Technical field
The utility model relates to a kind of electric machine flange end cap, and the good electric machine flange end cap of especially a kind of heat dispersion belongs to the motor component technical field.
Background technology
The normal version that adopts of current motor flange end cap is all similar with Y and Y2 series; All the motor bearings chamber is included in the inner chamber of motor sealing; Cause the motor bearings radiating condition very poor; Particularly some special installation temperature is very high, and the high temperature that produces of equipment is directly delivered to through end cap motor bearings and bearing grease life-span are all shortened greatly in use, serious motor bearings is burnt and cause motor integral body burning machine.
The utility model content
The utility model purpose is to have proposed the good electric machine flange end cap of a kind of heat dispersion for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of electric machine flange end cap comprises body; Said body comprises bearing chamber, big of flange, inner cavity chamber, brace rod; The big face of said flange is arranged on the outside of body; Said inner cavity chamber is arranged on the middle part of the inboard of body; Said bearing chamber is arranged on the middle part of inner cavity chamber; Said brace rod is arranged on the excircle of body.
Preferably, also be provided with the heat radiation reinforcement on the said electric machine flange end cap; Said heat radiation reinforcement is arranged on the excircle of body, and nearest with bearing chamber.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The described electric machine flange end cap of the utility model, when being installed on the motor, the wind energy that the fan in the motor produces has reduced customer equipment high temperature and has passed on the bearing in the bearing chamber big directly cooling of entire flange; Bearing in the bearing chamber has reduced the heat effects that winding produces away from winding simultaneously; Simultaneously the bearing chamber outer wall directly is exposed in the cooling air, and the wind energy that fan produces blows on the bearing chamber outer wall, has improved the radiating condition and the speed of bearing greatly; Simultaneously the bearing chamber outer wall has increased the area of dissipation that some radiating ribs have increased bearing; The utility model scenario-frame is simple, practical.

Embodiment
Be depicted as a kind of electric machine flange end cap of the utility model like accompanying drawing 1,2, comprise body; Said body comprises bearing chamber 1, big 2 of flange, inner cavity chamber 3, brace rod 4, heat radiation reinforcement 5; Big 2 outside that is arranged on body of said flange; Said inner cavity chamber 3 is arranged on the middle part of the inboard of body; Said bearing chamber 1 is arranged on the middle part of inner cavity chamber 3; Said brace rod 4 is arranged on the excircle of body; Said heat radiation reinforcement 5 is arranged on the excircle of body, and nearest with bearing chamber 1.
Be depicted as the application of said electric machine flange end cap on motor of the utility model like accompanying drawing 3, said electric machine flange end cap 12 is arranged on the left side of electric machine casing 17; Said fore bearing 11 is arranged in the bearing chamber 1 of electric machine flange end cap 12; Said fan housing 16 is arranged on the right side of electric machine casing 17; Said stator 14 is arranged on the inside of electric machine casing 17; Said rotor 13 passes a rotating shaft; Said rotor 13 is oppositely arranged with stator 14; One end of said rotating shaft is arranged in the fore bearing 11, and the other end is provided with fan 15; When rotor 13 work, fan 15 is also along with rotation, and the wind energy that fan 15 produces has reduced customer equipment high temperature and passed on the fore bearing 11 in the bearing chamber 1 big 2 directly cooling of entire flange; Fore bearing 11 in the bearing chamber 1 has reduced the heat effects that winding produces away from winding simultaneously; Simultaneously bearing chamber 1 outer wall directly is exposed in the cooling air, and the wind energy that fan 15 produces blows on bearing chamber 1 outer wall, has improved the radiating condition and the speed of fore bearing 11 greatly; Simultaneously bearing chamber 1 outer wall has increased the area of dissipation that some heat radiation reinforcements 5 have increased fore bearing 11; Thereby the heat dispersion of the electric machine flange end cap 12 of this programme is good.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The described electric machine flange end cap of the utility model, when being installed on the motor, the wind energy that the fan in the motor produces has reduced customer equipment high temperature and has passed on the bearing in the bearing chamber big directly cooling of entire flange; Bearing in the bearing chamber has reduced the heat effects that winding produces away from winding simultaneously; Simultaneously the bearing chamber outer wall directly is exposed in the cooling air, and the wind energy that fan produces blows on the bearing chamber outer wall, has improved the radiating condition and the speed of bearing greatly; Simultaneously the bearing chamber outer wall has increased the area of dissipation that some radiating ribs have increased bearing; The utility model scenario-frame is simple, practical.
Below only be the concrete exemplary applications of the utility model, the protection range of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
