Abstract
The utility model belongs to bearing holder (housing, cover) field, it is a kind of insulated bearing sleeve used for motor corrosion of bearing provided in order to block shaft current, comprise inner ring and outer shroud, between inner ring and outer shroud, there is gap, described inner ring and outer shroud are metal material and make, and are filled with the insulating barrier stoping electric current to flow between inner ring and outer shroud in the gap between inner ring and outer shroud.Described insulating barrier is thermoset plastics material.The beneficial effects of the utility model: insulating bearing carrier ring is assembled to after between the end cap of motor and bearing by the utility model, the shaft current that operating motor produces, just blocked by insulating bearing carrier ring, bearing also would not be subject to galvano-cautery, thus extend the useful life of motor, also reach the object of energy-conserving and environment-protective simultaneously.
Description
Technical field
The utility model belongs to bearing holder (housing, cover) field, particularly relates to a kind of insulating bearing carrier ring.
Background technology
Bearing holder (housing, cover) is the strength member in motor product, and how are its project organization, manufacturing technology level, has very important impact to the technical grade, performance, operational reliability, useful life, energy consumption, noise etc. of motor product.And the motor product bearing holder (housing, cover) of China, adopt steel manufacture for a long time, not there is insulating properties, Gu this cannot solve shaft current that motor produces in running in end cap the galvano-cautery that produces of the bearing that is equipped with, working face smooth for bearing is corroded spot is innumerable, rough and uneven in surface, the energy consumption causing motor to run increases, noise increases, shortening in useful life, and disagrees with the energy-saving and environmental protection policy of country.
Utility model content
The purpose of this utility model is a kind of insulating bearing carrier ring provided the corrosion of bearing to block shaft current.
The utility model is achieved by the following technical solution:
Insulated bearing sleeve used for motor, comprises inner ring and outer shroud, between inner ring and outer shroud, has gap, and described inner ring and outer shroud are metal material and make, and is filled with the insulating barrier stoping electric current to flow between inner ring and outer shroud in the gap between inner ring and outer shroud.
Described insulating barrier is thermoset plastics material.
In the circumferential exterior surface of inner ring and/or the circumferential inner surface of outer shroud, there is draw-in groove.
Described draw-in groove is cannelure and/or deep-slotted chip breaker.
The beneficial effects of the utility model: insulating bearing carrier ring is assembled to after between the end cap of motor and bearing by the utility model, the shaft current that operating motor produces, just blocked by insulating bearing carrier ring, bearing also would not be subject to galvano-cautery, thus extend the useful life of motor, also reach the object of energy-conserving and environment-protective simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model cutaway view.
Fig. 2 is vertical view of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment one
As depicted in figs. 1 and 2, insulated bearing sleeve used for motor, comprise inner ring 2 and outer shroud 1, between inner ring 2 and outer shroud 1, there is gap, described inner ring and outer shroud are metal material and make, and are filled with the insulating barrier 3 stoping electric current to flow between inner ring 2 and outer shroud 1 in the gap between inner ring 2 and outer shroud 1.Described insulating barrier 3 is thermoset plastics material.In the circumferential exterior surface of inner ring, there is draw-in groove.Described draw-in groove is cannelure and/or deep-slotted chip breaker.
Embodiment two
Insulated bearing sleeve used for motor, comprises inner ring and outer shroud, between inner ring and outer shroud, has gap, and described inner ring and outer shroud are metal material and make, and is filled with the insulating barrier stoping electric current to flow between inner ring and outer shroud in the gap between inner ring and outer shroud.Described insulating barrier is thermoset plastics material.In the circumferential inner surface of outer shroud, there is draw-in groove.Described draw-in groove is cannelure and/or deep-slotted chip breaker.
Embodiment three
Insulated bearing sleeve used for motor, comprises inner ring and outer shroud, between inner ring and outer shroud, has gap, and described inner ring and outer shroud are metal material and make, and is filled with the insulating barrier stoping electric current to flow between inner ring and outer shroud in the gap between inner ring and outer shroud.Described insulating barrier is thermoset plastics material.All there is draw-in groove in the circumferential exterior surface of inner ring and the circumferential inner surface of outer shroud.Described draw-in groove is cannelure and/or deep-slotted chip breaker.
In above embodiment, the setting of draw-in groove increases the tightness between inner ring and outer shroud, enables its life-span longer.Draw-in groove also can be designed as and multiplely also can be designed as one.
The bearing holder (housing, cover) of metal is resolved into outer shroud and inner ring two parts, and leave certain gap at outer shroud and interior interannular, then with the thermoset plastics with insulation property, in a mold by under certain pressure and temperature, thermoset plastics is made to be filled in the gap of outer shroud and inner ring, after thermoset plastics solidification, make it to become the insulating bearing carrier ring with insulation property.Between the inner and outer ring in this bearing holder (housing, cover), owing to being filled with thermoset plastics, electric current cannot be flowed between inner and outer ring.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, simple change and the replacement of those ordinary skill in the art are all within protection range of the present utility model.
Claims (4)
