Abstract
The invention discloses a bearing insulation structure. Insulated layers/an insulated layer are/is disposed on the outer sleeve and/or the inner sleeve of a bearing. Each insulated layer comprises an outer insulated sleeve disposed on the outer side of the bearing, an inner insulated sleeve disposed on the inner side of the bearing, and an insulated pad disposed on the side surface of the bearing. The bearing insulation structure has advantages that the insulated sleeves and the insulated pad wrap the bearing sleeve so that a common bearing may substitute for an insulated bearing to block shaft current and achieve bearing insulation, thereby prolonging the service life of the bearing. In addition, the bearing insulation structure is simple in processing technology and low in cost, can be used by various motors, and has high economical efficiency.
Description
Technical field
The present invention relates to machine field, is a kind of bearing insulation structure specifically.
Background technology
As shown in Figure 1, constituted the conductor of shaft current by axle 1, bearing 2, internal bearing cover 3, end cap 6, enclosing cover 7, in figure, dotted line represents shaft current to existing electric machine structure; Due to the existence of shaft current, it produces galvano-cautery when flowing through rolling element, thus reduces bearing useful life, causes bearing damage.For solving this problem, general employing itself has the Imported Insulation bearing of insulation function, and its cost is high, and it is difficult to buy, and causes certain influence to production motor.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of bearing insulation structure, this structure can adopt plain bearing to replace Imported Insulation bearing, and concrete technical scheme is as follows:
A kind of bearing insulation structure, arrange insulating barrier at the overcoat of bearing and/or inner sleeve, described insulating barrier flows through the electric current of bearing roller for blocking;
Described insulating barrier comprises and is arranged on external insulation sleeve outside bearing, is arranged on the interior insulating case inside bearing and is arranged on the insulation cushion of bearing side.
Described interior insulating case comprises interior insulation body and is arranged on the insulating coating of interior insulating case end of body, and described insulating coating is for blocking the electrical connection of interior insulation body and other conductors.
Described external insulation sleeve comprises external insulation body and is arranged on the insulating coating of external insulation sleeve end of body, and described insulating coating is for blocking the electrical connection of external insulation body and other conductors.
Advantage of the present invention is: surround bearing holder (housing, cover) with insulating case and insulation cushion, plain bearing can be adopted to replace insulation bearing, block shaft current, realize bearing insulation, improves bearing useful life; In addition, processing technology of the present invention is simple, and cost is low, can be used for various motor, has higher economy.

Embodiment
Illustrate the present invention below in conjunction with accompanying drawing, as Figure 2-Figure 5, arrange insulating barrier at the overcoat of bearing 2 and/or inner sleeve, described insulating barrier flows through the electric current of bearing roller for blocking;
Described insulating barrier comprises and is arranged on external insulation sleeve 5 outside bearing, is arranged on the interior insulating case 8 inside bearing and is arranged on the insulation cushion 4 of bearing side.
Described interior insulating case 8 comprises interior insulation body 81 and is arranged on the insulating coating 9 of interior insulating case end of body, and described insulating coating 9 is for blocking the electrical connection of interior insulation body 81 and other conductors.
Described external insulation sleeve 5 comprises external insulation body 51 and is arranged on the insulating coating 9 of external insulation sleeve end of body, and described insulating coating 9 is for blocking the electrical connection of external insulation body 51 and other conductors.
Above embodiment is only used for the present invention is described, can also adopt other forms of insulating barrier to block the electric current flowing through bearing roller; As namely adopted external insulation sleeve 5, insulating case 8 and insulation cushion 4 etc. in also adopting.
