Abstract

The utility model discloses a novel motor end cover comprising a cover body (1) and a bearing seat (2) which protrudes upward in the middle part of the cover body (1). An outer wall of the bearing seat (2) is provided with a plurality of heat radiating ribs (3). The novel motor end cover is simple in structure, the bearing is far away from a heating source of a motor, heat which is transferred to the bearing due to thermal radiation is reduced, a heat radiating area is increased, and a heat radiating effect is raised.

Description

A kind of Novel motor end cap

Technical field:

The utility model relates to a kind of Novel motor end cap.

Background technology:

Along with market competition is more and more fierce, requirement to life-span of motor is more and more higher, bearing arrangement is as the most important part of motor, its life-span directly affects the useful life of motor, be exactly the life-span of bearing lubrication grease and affect the topmost reason of bearing of motor lifetime of system, bearing temperature is higher, and the bearing grease volatilization is faster, dry faster, the life-span then reduces faster.

Summary of the invention:

The purpose of this utility model is for the technological deficiency that exists in the prior art, and a kind of Novel motor end cap is provided, and this is simple in structure, make bearing away from the pyrotoxin of motor, reduce because thermal radiation heat passes to the heat of bearing, increasing heat radiation area, improving radiating effect.

The purpose of this utility model is to be achieved by following technical scheme.

A kind of Novel motor end cap comprises the end cap body, the bearing pedestal that end cap body middle part is protruding upward, and the bearing pedestal outer wall is provided with some radiating ribs.

Some radiating ribs described above are asymmetric to be evenly distributed on the end face of end cap body, is radiated entends.

Radiating ribs described above is low inside and high outside, the inclination certain angle.

Offer bearings mounted bearing chamber in the middle of the bearing pedestal described above.

End cap body end face middle part described above is provided with groove.

End cap body bottom surface described above is provided with some reinforcements.

Boss is protruded in end cap body bottom surface described above, and some reinforcements are positioned at the boss outside, are radiated entends.

Reinforcement described above is high outside and low outside, the inclination certain angle.

End cap body described above is provided with some installing holes.

End cap body, bearing pedestal and radiating ribs described above is the one cast aluminium forming.

The beneficial effects of the utility model are: 1) the utility model comprises the end cap body, the bearing pedestal that end cap body middle part is protruding upward, the bearing pedestal outer wall is provided with some radiating ribs, simple in structure, make bearing away from the pyrotoxin of motor, reduce because thermal radiation heat passes to the heat of bearing, increasing heat radiation area, improving radiating effect; 2) on the asymmetric end face that is evenly distributed on the end cap body of some radiating ribs, be radiated entends, strengthen end cap intensity, prevent the regular distortion of end cap die casting symmetry, and increase end cap end face and bearing chamber surface radiating area, improving radiating effect; 3) end cap body bottom surface is provided with some reinforcements, and some reinforcements are radiated entends, strengthens end cap intensity, increases end cap end face and bearing chamber surface radiating area, good heat dissipation effect; 4) end cap body, bearing pedestal and radiating ribs are the one cast aluminium formings, reasonable in design, applicable batch production.

Embodiment:

Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model is a kind of Novel motor end cap, comprises end cap body 1, the bearing pedestal 2 that end cap body 1 middle part is protruding upward, and bearing pedestal 2 outer walls are provided with some radiating ribs 3; Some radiating ribs 3 is asymmetric to be evenly distributed on the end face of end cap body 1, is radiated entends; Radiating ribs 3 is low inside and high outside, the inclination certain angle; Offer bearings mounted bearing chamber 6 in the middle of the bearing pedestal 2; End cap body 1 end face middle part is provided with groove 11; End cap body 1 bottom surface is provided with some reinforcements 4; Boss 12 is protruded in end cap body 1 bottom surface, and some reinforcements 4 are positioned at boss 12 outsides, are radiated entends; End cap body 1 is provided with some installing holes 5; Described end cap body 1, bearing pedestal 2 and radiating ribs 3 are one cast aluminium formings.

Reduce because thermal radiation heat passes to the heat of bearing away from the pyrotoxin of motor the utility model bearing with end cover chamber 6; Some radiating ribs 3 is asymmetric to be evenly distributed on the end face of end cap body 1, is radiated entends, strengthens end cap intensity, prevents the regular distortion of end cap die casting symmetry, and increases end cap end face and bearing chamber surface radiating area, improving radiating effect.
