Abstract
The utility model discloses a non-driving-end insulated cover of an electric motor of a rail grinding wagon, and relates to an end cover of the electric motor, in particular to a non-driving-end insulated cover of an electric motor of a rail grinding wagon. The non-driving-end insulated cover mainly solves the problem of electric corrosion of a bearing due to discharge of voltage of a shaft for the bearing when the electric motor of the rail grinding wagon works. The non-driving-end insulated cover comprises a non-driving-end insulated cover bearing of the electric motor and a bearing cover, and is characterized in that the non-driving-end insulated cover bearing of the electric motor comprises an end cover inner ring and an end cover outer ring, wherein an insulation layer is arranged between the end cover inner ring and the end cover outer ring, a fixed bolt between the end cover and the bearing cover is provided with an insulation sleeve, and an insulation layer is arranged between the end cover and the bearing cover. According to the utility model, the non-driving-end insulated cover bearing of the electric motor and the bearing are insulated, so that the electric corrosion of a non-driving-end bearing is eliminated, and the damage of the bearing is avoided.
Description
Technical field
The utility model relates to a kind of rail grinding machine End cover for motor, relates to a kind of steel rail grinding tramcar motor non-transmision end insulated end cover specifically.
Background technology
At present; Known rail grinding machine moves (rated frequency 120HZ rated voltage 575V) under rated condition, because of high-frequency, high voltage, motor produces bigger shaft voltage when work; Shaft voltage can discharge to bearing; Produce galvano-cautery, damage bearing when serious, and motor is blocked and burn-out motor.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned deficiency, and provide a kind of when machine operation, can not make the steel rail grinding tramcar motor non-transmision end insulated end cover of motor non-transmision end bearing galvano-cautery.
The technical solution of the utility model is: steel rail grinding tramcar motor non-transmision end insulated end cover; Comprise motor non-transmision end end cap, bearing and bearing cap; It is characterized in that motor non-transmision end end cap is made up of end cap inner ring and end cap outer ring, be provided with insulating barrier between end cap inner ring and the end cap outer ring; Set bolt between end cap and the bearing cap is provided with insulating case, is provided with insulating barrier between end cap and the bearing cap.
Insulating barrier described in the technical solution of the utility model is no latitude band.
Insulating barrier between end cap inner ring described in the technical solution of the utility model and the end cap outer ring is connected as a single entity end cap inner ring and end cap outer ring through hot cover process.
The utility model is owing to be equipped with insulated end cover on steel rail grinding tramcar motor non-transmision end; And pass through insulating case with end cap and bearing insulation; The shaft voltage of having avoided the steel rail grinding tramcar motor when work, to produce discharges to bearing; And make the galvano-cautery of non-transmision end bearing, avoid damaging bearing, and motor is blocked, the accident of burn-out motor takes place.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The steel rail grinding tramcar motor insulated end cover of the utility model is installed in steel rail grinding tramcar motor non-transmision end, and insulated end cover is made up of end cap inner ring 2 and end cap outer ring 1, is provided with insulating barrier 4 between end cap inner ring 2 and the end cap outer ring 1; Insulating barrier 4 is no latitude bands; Through hot cover process end cap inner ring 2 and end cap outer ring 1 are connected as a single entity, cool off dipping lacquer then, be machined to the figure paper size more together; The bolt of assembling end cap and bearing cap 6 is provided with insulating case 5, through the insulating case on the bolt 5 bearing cap 6 and insulated end cover is separated, and insulate; Junction between end cap and the bearing cap 6 is provided with insulating barrier; Insulating barrier is no latitude band; By no latitude band end cap and bearing cap 6 are separated and to insulate; The utility model produces shaft voltage when having avoided the work of steel rail grinding tramcar motor bearing is discharged because electric motor end cap and bearing 3 have been carried out insulation processing, has eliminated the problem of non-transmision end bearing galvano-cautery.
