Description
Technical field
The present invention relates to the motor bearings lubrication system, specifically is a kind of motor bearings lubricating system.
Background technology
The operating mode of wind-driven generator is comparatively harsh usually.If generator is because bearing problem causes compressor emergency shutdown or changes generator; the economic loss that is caused is quite huge; so require under non-stop-machine situation, bearing to be added grease lubrication, and when assurance is lubricated, must guarantee that the working temperature of bearing remains under a certain temperature.As shown in Figure 1, existing motor bearings lubrication system generally includes end cap 1, seal ring 2, inside cap 3 and outer bearing cover 4.Outer bearing cover 4 row's of being provided with fat mouths 5.During machine operation, bearing 12 is assemblied on the machine shaft 13, supports rotor by end cap 1.When adding grease lubrication, lubricating grease is lubricated bearing by oil circuit between end cap, seal ring, inside cap, outer bearing cover, the bearing and gap, and unnecessary lubricating grease is discharged by row's fat mouth of being located on the outer bearing cover.Practice shows, because self structure restriction, in use there are the following problems for existing motor bearings lubrication system: one, the sealing between end cap, inside cap, the outer bearing cover is relatively poor, causes lubricating grease from the gap seepage between end cap, inside cap, the outer bearing cover easily.Two, lubricating grease throws away under the seal ring centrifugal action easily, is unfavorable for the preservation of lubricating grease, makes lubrication circumstances worsen.Three, the sealed pathway between seal ring, the outer bearing cover is shorter, and sealing effectiveness is poor, causes extraneous foreign matter to enter bearing easily.Four, row's fat mouth of being located on the outer bearing cover is less, and waste and old and unnecessary lubricating grease viscosity is bigger, is difficult for discharging, and causes lubricating grease to pile up in outer bearing cover easily, causes the bearing chamber heating.Based on this, be necessary to invent a kind of brand-new motor bearings lubrication system, with solve existing motor bearings lubrication system in use the lubricating grease easy to leak, easily throw away, easily in outer bearing cover, pile up and cause extraneous foreign matter to enter the problem of bearing easily.
Summary of the invention
The present invention provides a kind of motor bearings lubricating system in order to solve existing motor bearings lubrication system in use lubricating grease easy to leak, the problem that easily throws away, easily pile up and cause extraneous foreign matter to enter bearing easily in outer bearing cover.
The present invention adopts following technical scheme to realize: the motor bearings lubricating system comprises end cap, seal ring, inside cap and outer bearing cover; Outer bearing cover is provided with row's fat mouth; The end cap inboard is socketed with bearing chamber, and inside cap is installed on the inner side end of bearing chamber, and between the inner side end of the outside end face of inside cap and bearing chamber an O RunddichtringO is installed; Bearing chamber outside end face is equipped with oil scraper ring, and the 2nd O RunddichtringO is installed between the outside end face of the inner side end of oil scraper ring and bearing chamber; Outer bearing cover is installed on the outside end face of oil scraper ring, and between the outside end face of the inner side end of outer bearing cover and oil scraper ring the 3rd O RunddichtringO is installed; Seal ring is socketed on the outer bearing cover inboard, is provided with labyrinth seal between the outside end face of seal ring and the inner side end of outer bearing cover; The axis of the axis of the axis of the axis of end cap, the axis of seal ring, inside cap, the axis of outer bearing cover, bearing chamber, the axis of an O RunddichtringO, oil scraper ring, the axis of the 2nd O RunddichtringO, the axis of the 3rd O RunddichtringO all are located along the same line.
During work, bearing is assemblied on the machine shaft, by bearing chamber, endcap support electrizer rotor.Seal ring, inside cap are socketed on the machine shaft.When adding grease lubrication, lubricating grease is lubricated bearing by oil circuit between end cap, seal ring, inside cap, outer bearing cover, bearing chamber, oil scraper ring, the bearing and gap, and unnecessary lubricating grease is discharged by row's fat mouth of being located on the outer bearing cover.Based on said process, compare with existing motor bearings lubrication system, motor bearings lubricating system of the present invention has following advantage: one, by setting up bearing chamber, and between bearing chamber, inside cap, outer bearing cover, set up an O RunddichtringO, the 2nd O RunddichtringO, the 3rd O RunddichtringO, prevented the lubricating grease seepage.Two, by setting up oil scraper ring, prevented that lubricating grease from throwing away under the seal ring centrifugal action, stored lubricating grease effectively, for the lubricated necessary condition that provides of secondary is provided lubricating grease.Three, by between seal ring and outer bearing cover, labyrinth seal being set, prolonged the sealed pathway between seal ring and the outer bearing cover, and prevented that extraneous foreign matter from entering bearing.In sum, motor bearings lubricating system of the present invention is by adopting brand-new hermetically-sealed construction, efficiently solve existing motor bearings lubrication system in use the lubricating grease easy to leak, easily throw away, cause easily extraneous foreign matter to enter the problem of bearing.
Further, described row's fat mouth is an extended type row fat mouth.Extended type row fat mouth has made things convenient for waste and old and unnecessary lubricating grease to discharge, and has prevented that lubricating grease is deposited in the outer bearing chamber, has reduced the heating of bearing chamber.
In addition, the outside end face of seal ring is equipped with nut, and the axis of nut and the axis of seal ring are located along the same line.During work, nut is fixed on the machine shaft, can prevent that seal ring from sliding along rotating shaft.
The present invention is based on brand-new hermetically-sealed construction, efficiently solve existing motor bearings lubrication system in use the lubricating grease easy to leak, easily throw away, easily in outer bearing cover, pile up and cause extraneous foreign matter to enter the problem of bearing easily, be applicable to the bearing lubrication of motor, be particularly useful for the bearing lubrication of wind-driven generator.
