Abstract
The utility model discloses a bearing insulation structure for a high-voltage motor. The bearing insulation structure comprises a bearing sleeve, an end cover, insulating layers, a bolt and a lining, wherein the insulating layers are arranged between the bearing sleeve and the lining, between the end cover and the bearing sleeve, and between the bolt and the end cover; the end cover is fixed with the bearing sleeve through the bolt; and the lining is positioned below the end cover. By adopting the bearing insulation structure, the end cover and the bearing sleeve are insulated from each other, so that shaft current is prevented from passing through a bearing and from burning out the motor bearing.
Description
Technical field
The utility model relates to a kind of high-tension motor, particularly a kind of bearing insulation structure of high-tension motor.
Background technology
At present; The bearing assembly structure of high-tension motor all is a tape insulation not; Will produce electric discharge phenomena when the shaft current process bearing enclose of motor generation in service and roller; The galvano-cautery bearing arrangement can cause bearing to burn out when serious or during long operational time, causes motor to be stopped transport and influences enterprise production.
The utility model content
The utility model technical problem to be solved provides a kind of bearing insulation structure of high-tension motor, and it makes between end cap and the bearing holder (housing, cover) and insulate, thereby has prevented that shaft current from through bearing, preventing that shaft current from burning out bearing of motor.
For solveing the technical problem; The utility model provides a kind of bearing insulation structure of high-tension motor; It is characterized in that the bearing insulation structure of high-tension motor comprises bearing holder (housing, cover), end cap, insulating barrier, bolt, lining, between bearing holder (housing, cover) and the lining, between end cap and the bearing holder (housing, cover), all be provided with insulating barrier between bolt and the end cap; End cap is fixed through bolt and bearing holder (housing, cover), and lining is positioned at the below of end cap.
Preferably; The bearing insulation structure of said high-tension motor also comprises bearing, bearing end cover, oil scraper ring, internal bearing cover; Bearing is positioned at the below of bearing holder (housing, cover); Bearing end cover is connected with an end, the bearing of bearing holder (housing, cover), and oil scraper ring is positioned at the below of bearing end cover, and internal bearing cover is connected with the other end of bearing holder (housing, cover).
The positive progressive effect of the utility model is: the utility model makes between end cap and the bearing holder (housing, cover) and insulate, thereby has prevented that shaft current from through bearing, preventing that shaft current from burning out bearing of motor.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.
As shown in Figure 1; The bearing insulation structure of the utility model high-tension motor comprises bearing holder (housing, cover) 1, end cap 2, insulating barrier 3, bolt 4, lining 5, bearing 6, bearing end cover 7, oil scraper ring 8, internal bearing cover 9; Between bearing holder (housing, cover) 1 and the lining 5, between end cap 2 and the bearing holder (housing, cover) 1, all be provided with insulating barrier 3 between bolt 4 and the end cap 2, end cap 2 is fixing with bearing holder (housing, cover) 1 through bolt 4, and lining 5 is positioned at the below of end cap 2; Bearing 6 is positioned at the below of bearing holder (housing, cover) 1; Bearing end cover 7 is connected with an end, the bearing 6 of bearing holder (housing, cover) 1, and oil scraper ring 8 is positioned at the below of bearing end cover 7, and internal bearing cover 9 is connected with the other end of bearing holder (housing, cover) 1.
The installation process of the bearing insulation structure of the utility model high-tension motor is following: between bearing holder (housing, cover) 1 and lining 5, add earlier a layer insulating 3; And firmly be integral; Then at insulating barrier 3 on the pad respectively between end cap 2 and the bearing holder (housing, cover) 1, between bolt 4 and the end cap 2; Finally make insulation between end cap 2 and the bearing holder (housing, cover) 1; Thereby prevented that shaft current from through bearing, having avoided shaft current to the galvano-cautery of bearing and the generation of burning problem, the problem that consequent motor is stopped transport and influence is produced has not taken place.
Though more than described the embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these execution modes.Therefore, the protection range of the utility model is limited appended claims.
Claims (2)
