Description
Technical field
The utility model relates to machine field, and particularly a kind of be applied in the motor is the system of bearing oiling.
Background technology
The y series motor that is applied in the compressor has efficient, energy-conservation, the advantages such as noise is low, the vibration is little, lightweight, dependable performance, and motor must guarantee that in running the lubricated of bearing could work.At present common y series motor is mostly without the bearing oil injection structure, and bearing oiling or when changing oil need to be waited until the motor overhaul or takes motor apart when breaking down and just can carry out.Though the Y2 serial motors is improved, can only supplemental lubrication fat, can not realize that old grease upgrades.
For motor can or be changed oil in the holding state oiling, people have designed simple injection system at motor, as shown in Figure 1.Bearing is arranged on the step place of motor output multidiameter, the outer ring of bearing by be arranged on internal bearing cover in the thicker rotating shaft, be arranged on the bearing end cover in the thinner rotating shaft and be arranged on internal bearing cover and bearing end cover between rear end cap position; Be provided with oil filler point and flowline on the rear end cap, be provided with the circular passage that is connected with oil filler point and flowline between bearing end cover and the bearing.When bearing was carried out oiling, lubricating grease injected from oil filler point, entered bearing and thinner rotating shaft by the circular passage, then flowed out from flowline.
The Y2 serial motors of this kind structure, because between bearing end cover and the bearing inner race and the gap between internal bearing cover and the bearing inner race is larger, increase so that flow to the leakage of oil amount of multidiameter, cause the new lubricating grease that replenishes in the bearing less, can not realize bearing is well lubricated, more can not realize whole replacings of old lubricating grease; Secondly because oiling and fuel-displaced all be between bearing and bearing end cover, to realize, can only realize the lubricating grease in the bearing outside is changed, and the lubricating grease between bearing and internal bearing cover can not get thorough replacing; The 3rd, the injection system of this kind structure is because flowline is thinner, stop up easily, a large amount of greases spill from axis hole, when the lubricating grease of the motor internal lubricating grease in particular for the bearing inboard, can become dirty when service time is long and with more impurity, affect the normal operation of motor; As think thoroughly to change inner lubricating grease, overhaul must be waited until or lubricating grease could be thoroughly more renewed when breaking down.In addition; the Y2 serial motors that is designed with at present injection system can only could thoroughly be changed lubricating grease under stopped status; yet large and middle size motor is important production equipment, does not allow interim or long-time the shutdown in the time of at short notice, therefore can not guarantee reliably the good lubrication of bearing in motor.
The utility model content
It is the injection system of replaceable new lubricating grease in stopped status not that the utility model technical issues that need to address provide a kind of motor of can realizing.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows.
Motor is not shut down injection system; the rear end cap that comprises the mounted motor bearing; internal bearing cover and bearing end cover; the top of back end cover for motor is provided with oil filler point; the rear end cap bottom is provided with flowline; be provided with an end is communicated with oil filler point by the oiling passage that is positioned on the rear end cap in the inboard of motor bearings inner cap; the annular groove that the other end is corresponding with inboard bearing inner race and the raceway gap between the outer ring; the arranged outside of described bearing has the oil that gets rid of that is installed on the machine shaft to fan; the inboard of bearing end cover is provided with and holds the cavity that gets rid of the oil fan, and the lower end of cavity is communicated with the flowline top.
Improvement of the present utility model is: describedly get rid of oily fan pass and cross the outside that circlip for shaft is pressed on bearing.
Of the present utility modelly further be: the bottom of described annular groove is provided with corresponding with the cylindrical height of bearing inner race and near the Oil Guide slope of bearing inner race.
Improvement of the present utility model also is: the position relative with getting rid of the oil fan, the bottom of described rear end cap cavity is provided with the oil-discharging cavity that is communicated with the flowline top.
Because the technological progress of having adopted technique scheme, the utility model to obtain is as follows.
The utility model utilizes the pressure characteristic of lubricating grease, uses and gets rid of oil fan and reasonably lubricating grease injection and decompression discharge structure, so that many bends path that lubricating grease flows has obtained minimizing, has increased oil extraction power and leakage of oil resistance; The lubricating grease path raceway gap between annular groove, bearing inner race and the outer ring between internal bearing cover and the bearing of flowing through successively, gets rid of oil fan, flowline from the rear end cap top, flow at last in the grease box.Oil filler point directly is connected with oiling machine during use; lubricating grease under the rotation of getting rid of the oil fan and the Action of Gravity Field of self, enters oil-discharging cavity after oil filler point injects; then flow into grease box from oil-out by fan housing through flowline, realized not tearing machine open and do not shut down the replacing of situation lower bearing lubricating grease.And in the process that lubricating grease is changed, the side direction bearing outside in bearing of the oil circuit in the injection system is injected, and does not have the dead angle, can thoroughly lubricating grease all in the bearing chamber be replaced, have program succinctly, the advantage of environment-friendly high-efficiency.
The circlip for shaft that the utility model arranges is used for getting rid of the oil fan and firmly is pressed on the bearing outside, prevents from getting rid of the oil fan and slides in rotating shaft in the High Rotation Speed process.The setting on Oil Guide slope in the described annular groove is Oil Guide type structure with original oil-storage architecture advances, makes lubricating grease in the process of injecting to bearing, can import smoothly bearing; The setting of Oil Guide slope structure is gone back so that the gap between internal bearing cover and bearing inner race has obtained reducing, thereby has been reduced the leakage of oil amount of injection system to rotor shaft direction.The setting of rear end cap lower tip oil-discharging cavity can make and get rid of the lubricating grease that oil fan outer ring flabellum throws away and flock together, and then the flowline from the oil-discharging cavity below flows out.
