Description
Technical field
The utility model belongs to motor appurtenances technical field, is a kind of low voltage motor bearing injection-discharge oil device.
Background technique
In the running of high-rating generator; as the bearing that connects machine shaft and end cap; bearing greatly and be the radial and axial load of alternation; therefore lubricated in its running seems particularly important; in case insufficient lubrication occurs, then can cause because of the bearing breakage or burn to cause stopping accident.And the repair and replacement of bearing bother very much, generator ' s cover, bearing and rotor all must be dismantled disintegration after, the bearing that could more renew, adopt the hot pressing assembling between bearing and the machine shaft, its dismounting difficulty is very big, will bring very big economic loss to the user in addition.And in existing technology, to lubricating of motor bearings, normally on bearing end cover and bearing (ball) cover, offer a horizontal oil hole, the lubricating grease that is injected by oil hole enters the rubbing surface of bearing, and bearing is lubricated and cools off, and heats up and thinning through pivot friction, inflow remains in the cavity between bearing end cover inwall and the bearing, on bearing end cover, be provided with a oil drainage hole, regularly screw out plug, again waste oil is discharged with the plug sealing.The defective that this notes oil extraction mode exists is: waste oil is aged deterioration at high temperature, and carry metallic dust, long-term aggregated, be trapped in the cavity between bearing end cover inwall and the bearing, be easy to be back to the facial position of pivot friction, cause the pollution of new supplemental lubrication fat, cause lubrication failure, premature wear and the damage of bearing and the waste of lubricating grease.And, lacking effective seal between bearing end cover and the machine shaft, outside dust enters pivot friction face easily thus, influences the lubrication effect of bearing.In addition, the motor ventilating fan end needs shutdown, dismounting fan guard and plug when annotating oil extraction, can carry out, very trouble.Up to now, this problem does not also obtain comparatively desirable solution.
The model utility content
The purpose of this utility model provides a kind of immersion of dust, water dirt and oil circuit of can preventing effectively and stops up, guarantee the cleaning of lubricating grease, the rotten waste and the backflow thereof of stopping lubricating grease, and also rational in infrastructure, greasy property is reliable, the low voltage motor bearing injection-discharge oil device that oiling is easy to operate.
Realize that the technological scheme that the purpose of this utility model is taked is: this device comprises electric motor end cap, machine shaft, motor bearings, bearing end cover and internal bearing cover, wherein, the top of electric motor end cap is provided with the oiling port hole, the bearing of internal bearing cover compresses end face and is provided with the annular oil groove that is communicated with described oiling port hole and bearing, the exterior edge face of bearing end cover is provided with the annular opening oil-discharge trough that is communicated with bearing, its opening part is provided with the disc of fixedlying connected with machine shaft, and the bottom of bearing end cover is provided with the oil drainage hole that is communicated with described oil-discharge trough.
Be provided with annular seal groove in the described oil-discharge trough, the V-arrangement elastic seal ring is housed in the sealing groove.
The circumference that described disc cooperates with oil-discharge trough is provided with the oil seal groove.
Oil filler pipe and pump nozzle are equipped with in the top of described oiling port hole, and oil filler pipe is fixedlyed connected with motor fan housing by sending out blue cover.
The low voltage motor bearing injection-discharge oil device of making according to such scheme, its oil channel structures is reasonable in design, greasy property is reliable, and whole oil circuit sealing circulation, the immersion and the oil circuit that can prevent dust, water dirt effectively stop up, and guarantee the cleaning of lubricating grease, the rotten waste and the backflow thereof of stopping lubricating grease, make bearing can access good lubricated and cooling all the time, and the notes oil extraction is very convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, low voltage motor bearing injection-discharge oil device of the present utility model, comprise electric motor end cap 1, internal bearing cover 3, bearing end cover 4, machine shaft 7 and motor bearings 8, wherein, be provided with oiling port hole 2 on the top of electric motor end cap 1, oil filler pipe 12 and pump nozzle 14 are equipped with in the top of oiling port hole 2, and oil filler pipe 12 is fixedlyed connected with motor fan housing 15 by sending out blue cover 13.The bearing of internal bearing cover 3 compresses end face and is provided with annular oil groove 3-1, and this annular oil groove 3-1 is communicated with the oiling port hole 2 and the bearing 8 on electric motor end cap 1 top, and constitutes the oiling passage of motor bearings 8.Be provided with the annular opening oil-discharge trough 5 that can be communicated with bearing 8 on the exterior edge face of bearing end cover 4, its opening part is provided with disc 6, and this disc 6 is with machine shaft 7 fixedly connected and rotations.On disc 6 and circumference that oil-discharge trough 5 cooperates, be provided with the oil seal groove 6-1 that is used to prevent oil leak, in the fluid in the oil-discharge trough 5 enters this oil seal groove 6-1, formation is to the oil seal in gap between disc 6 and the oil-discharge trough 5, can prevent entering of the leakage of oil-discharge trough 5 inner fluids and outside dust, water dirt, and the fitting surface of disc 6 with oil-discharge trough 5 is lubricated.The exterior edge face of bearing end cover 4 is provided with the annular seal groove 9 that is communicated with bearing 8, V-arrangement elastic seal ring 10 is housed in the groove, be used for the sealing of oil-discharge trough 5, when the waste oil in the bearing 8 flow to disc 6 positions, under the centrifugal action of disc 6 rotations, get rid of to elastic seal ring 10 positions, and elastic seal ring 10 pressed off, waste oil is entered in the oil-discharge trough 5; And, then make V-arrangement elastic seal ring 10 distendings when the pressure of waste oil in the oil-discharge trough 5 during greater than external pressure, with oil-discharge trough 5 sealings, unlikely the releasing of waste oil is back to the pivot friction zone.The bottom of bearing end cover 4 is provided with the oil drainage hole 11 that is communicated with described oil-discharge trough 5, and the waste oil in the oil-discharge trough 5 can be discharged at any time.
Working principle before motor brings into operation, should be filled with lubricating grease earlier, to reduce the friction of bearing in motor bearings 8.Its method is that lubricating grease enters motor bearings 8 via the annular oil groove 3-1 on oiling port hole 2 and the internal bearing cover 3 under filling pressure, motor bearings 8 is lubricated by the pouring orifice injection lubricating grease on electric motor end cap 1 oiling port hole 2 tops.In motor operation course, through certain operation period, by the friction and the intensification of motor bearings 8, lubricating grease can dilute gradually, and flows into automatically in the cavity between disc 6 and the bearing 8.Because disc 6 is with machine shaft 7 rotations; centrifugal force by its generation gets rid of lubricant oil in the oil-discharge trough 5, and is discharged by the oil drainage hole 11 of bearing end cover 4 bottoms, in motor operation course; as long as regular grease up, and when grease up, need not shut down.
