Abstract

The utility model relates to a motor bearing chamber comprising a plastic cement shaft sleeve. A plurality of heat-dissipating fins distributed circumferentially and uniformly are disposed on the outer sidewall of the plastic cement shaft sleeve. A bearing sleeve is disposed on the top of the plastic cement shaft sleeve. A sheath is disposed on the top of the bearing sleeve. The motor bearing chamber is simple in structure and produced by plastic cement. The heat-dissipating fins are disposed on the outer sidewall of the plastic cement shaft sleeve. The bearing sleeve and the sheath are disposed on the top of the plastic cement shaft sleeve. Thus, in specific use, the motor bearing chamber is good in heat-dissipating performance, uneasy to rise in temperature, capable of being adapted to variation of the temperature of a motor bearing, and good in toughness in a motor operating process. Friction and relative movement caused by temperature cannot occur between the motor bearing and the interior of the bearing chamber. Therefore, the service lives of the bearing and the motor can be greatly prolonged.

Description

A kind of motor bearing chamber

Technical field

The utility model relates to a kind of motor bearing chamber.

Background technology

The electric motor end cap of conventional motors is directly deep into fore bearing position at present, it is indoor that bearing is directly installed to electric motor end cap fore bearing, motor in the running, is subject to the impact of centrifugal force and rising-heat contracting-cold, and the fore bearing outer ring of motor easily and the indoor circle collision friction of fore bearing of electric motor end cap, cause the distortion of fore bearing chamber, it is large that size becomes, and finally cause electrical machinery life decay, and the fore bearing cell structure of existing electric motor end cap is simple, heat dispersion is low, and useful life is short.

Utility model content

For solving the problems of the technologies described above, the utility model provides a kind of motor bearing chamber simple in structure, easy to use.

Motor bearing chamber of the present utility model, comprises plastic cement axle sleeve, and described plastic cement axle sleeve lateral wall is provided with the some radiating fin bars that are circularly and evenly distributed, and the top of plastic cement axle sleeve is provided with bearing sleeve, and the top of bearing sleeve is provided with sheath.

Compared with prior art the beneficial effects of the utility model are: motor bearing chamber of the present utility model is simple in structure, main body is made by plastic cement, the outer wall of plastic cement axle sleeve is provided with radiating fin bar, the top of plastic cement axle sleeve arranges bearing sleeve and sheath, perfect heat-dissipating in concrete use, be difficult for producing temperature rise, the change that can well adapt to motor bearings temperature is large, and in motor operation course, there is good toughness, motor bearings can, because of temperature problem and bearing chamber internal friction and relative motion, can not improve the life-span of bearing life and motor greatly.

Fig. 2 is the cutaway view of a kind of motor bearing chamber described in the utility model embodiment.

In figure:

1, plastic cement axle sleeve; 2, radiating fin bar; 3, bearing sleeve; 4, sheath.

Embodiment

Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.

As shown in Figure 1-2, a kind of motor bearing chamber, comprises plastic cement axle sleeve 1, and described plastic cement axle sleeve 1 lateral wall is provided with the some radiating fin bars 2 that are circularly and evenly distributed, and the top of plastic cement axle sleeve 1 is provided with bearing sleeve 3, and the top of bearing sleeve 3 is provided with sheath 4.

Motor bearing chamber of the present utility model is simple in structure, main body is made by plastic cement, the outer wall of plastic cement axle sleeve is provided with radiating fin bar, the top of plastic cement axle sleeve arranges bearing sleeve and sheath, and perfect heat-dissipating in concrete use is difficult for producing temperature rise, the change that can well adapt to motor bearings temperature is large, and in motor operation course, have good toughness, motor bearings can, because of temperature problem and bearing chamber internal friction and relative motion, can not improve the life-span of bearing life and motor greatly.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
