Abstract
The utility model discloses a kind of bearing insulation structure, in overcoat and/or the inner sleeve of bearing, insulating barrier is set; Described insulating barrier comprise be arranged on bearing outside external insulation sleeve, be arranged on the interior insulating case of bearing inner side and be arranged on the insulation cushion of bearing side.The utility model has the advantages that: with insulating case and insulation cushion, surround bearing holder (housing, cover), can adopt plain bearing to replace insulation bearing, blocking-up shaft current, realizes bearing insulation, improved bearing useful life; In addition, the utility model processing technology is simple, and cost is low, can be used for various motors, has higher economy.
Description
Technical field
The utility model relates to machine field, is a kind of bearing insulation structure specifically.
Background technology
Existing electric machine structure as shown in Figure 1, has consisted of the conductor of shaft current axle 1, bearing 2, internal bearing cover 3, end cap 6, enclosing cover 7, in figure, dotted line represents shaft current; Due to the existence of shaft current, it produces galvano-cautery when flowing through rolling element, thereby reduces bearing useful life, causes bearing damage.For addressing 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 to producing motor, causes certain influence.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of bearing insulation structure, and this structure can adopt plain bearing to replace Imported Insulation bearing, and concrete technical scheme is as follows:
A bearing insulation structure, arranges insulating barrier in overcoat and/or the inner sleeve of bearing, and described insulating barrier is for blocking the electric current of the bearing roller of flowing through;
Described insulating barrier comprise be arranged on bearing outside external insulation sleeve, be arranged on the interior insulating case of bearing inner side and be 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 being electrically connected to 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 being electrically connected to of external insulation body and other conductors.
The utility model has the advantages that: with insulating case and insulation cushion, surround bearing holder (housing, cover), can adopt plain bearing to replace insulation bearing, blocking-up shaft current, realizes bearing insulation, improved bearing useful life; In addition, the utility model processing technology is simple, and cost is low, can be used for various motors, has higher economy.

Embodiment
Below in conjunction with accompanying drawing, illustrate the utility model, as Figure 2-Figure 5, in overcoat and/or the inner sleeve of bearing 2, insulating barrier is set, described insulating barrier is for blocking the electric current of the bearing roller of flowing through;
Described insulating barrier comprise be arranged on bearing outside external insulation sleeve 5, be arranged on the interior insulating case 8 of bearing inner side and be 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 being electrically connected to 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 being electrically connected to of external insulation body 51 and other conductors.
Above embodiment is only used for illustrating the utility model, can also adopt other forms of insulating barrier to block the electric current of the bearing roller of flowing through; As adopted external insulation sleeve 5, insulating case 8 and insulation cushion 4 etc. in also adopting.
Claims (1)
