Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Figure 1, being the structural schematic diagram of retarder lubrication system provided by the embodiment of the utility model, the retarder
Lubrication system can be applied to mechanical transmission fields, especially automobile etc. in high-revolving retarder.Subtracting in the present embodiment
There is the axis hole 3 for passing through for shaft and the oil sealing in axis hole 32 on the shell 1 of fast device；And retarder lubrication system
Including being located at the inner surface of shell 1 and below the bearing mounting base 11 of oil sealing 2, the bottom plate of bearing mounting base 11 with ring
Around the oil storage tank 111 of oil sealing 2；There is the oil inlet 113 and oil outlet 114 being connected to oil storage tank 111 on bearing mounting base 11,
And there is Oil Guide muscle 112 in oil storage tank 111, will be got rid of by the shaft of high-speed rotation to storage in oil storage tank 111 by Oil Guide muscle 112
The lubricating oil of 111 side wall of oil groove is drained to oil sealing 2, and bearing mounting base 11 and Oil Guide muscle 112 can be with the retarders
Shell 1 is integrally formed.
Above-mentioned retarder lubrication system by the oil storage tank 111 of bearing mounting base 11 be arranged Oil Guide muscle 112, make due to
High speed gets rid of to the lubricating oil of 111 side wall of oil storage tank and can be drained to lubricating oil by Oil Guide muscle 112, carries out to shaft and oil sealing 2
Lubrication, and can also cooling down to oil sealing 2 avoids shaft and 2 dry friction of oil sealing from generating a large amount of heat and can not be in time to oil
Envelope 2, which carries out cooling, makes oil sealing 2 fail, and extends the service life of oil sealing 2, protects to speed reducer.
Specifically, as shown in connection with fig. 2, the height that Oil Guide muscle 112 protrudes from 2 surface of oil sealing is less than 11 bottom plate of bearing mounting base
Protrude from the height of oil sealing 2, in which: A is the height that Oil Guide muscle 112 protrudes from 2 surface of oil sealing, and B is that Oil Guide muscle 112 protrudes from
Difference in height between 11 bottom plate of height and bearing mounting base on 2 surface of oil sealing, the value range of A can be 3.8-4.2 millimeters, B's
Value range can be 0.3-0.6 millimeters；Certainly, in practice, the value range of the A and B are needed according to speed reducer
Overall dimensions and demand are determined.
Particularly, there are multiple Oil Guide muscle 112, the head end of Oil Guide muscle 112 is connected to oil storage tank 111 in oil storage tank 111
Side wall, end extend to the edge of axis hole 3, and lubricating oil can be made to flow to oil sealing 2 and Oil Guide muscle by the end of Oil Guide muscle 112
112 end will not touch the shaft；In addition, multiple Oil Guide muscle 112 are uniformly distributed circumferentially in oil storage tank 111, and
Multiple Oil Guide muscle 112, along the tangentially-arranged of the direction of rotation of shaft 13, enable lubricating oil to produce in high speed rotation in oil storage tank 111
Oil Guide muscle 112 is flowed into along the direction of rotation of shaft 13 under raw centrifugal force effect, oil sealing 2 is entered by Oil Guide muscle 112.
Certainly, in practice, quantity, distribution situation and the tangentially-arranged angle of Oil Guide muscle 112 can roots
Factually border is adjusted, and meets the lubricant effect of retarder under different situations.
Specifically, oil inlet 113 and oil outlet 114 are in 90 ° on bearing mounting base 11, and oil inlet 113 and oil outlet
There is at least one Oil Guide muscle 112 between 114.It is easier lubricating oil enter at oil sealing 2 and extends lubricating oil and oil sealing 2
Time of contact, be conducive to lubricating oil and take away the heat on oil sealing 2 to cool down to oil sealing 2 with this, then passes through oil outlet 114
Realize that the circulation of lubricating oil, the effective cooling effect for improving oil sealing 2 enable oil sealing 2 to work within a reasonable temperature range, prolong
Its long service life.
Particularly, the inner surface of shell 1 is equipped with the flow path for changing 11 outside lubricating oil of bearing mounting base
Drainage plate 12；One end of drainage plate 12 abuts with the side wall for the bearing mounting base 11 being located at oil inlet 113, the other end and shell
1 edge connection, and lubricating oil is guided to enter bearing mounting base 11 and oil storage tank 111 by oil inlet 113, bearing can be made
What the lubricating oil of 11 outside of mounting base was more easier is entered in bearing mounting base 11 by oil inlet 113, enhances following for lubricating oil
Ring and the oil reserve for guaranteeing oil storage tank 111 in bearing mounting base 11 further push lubricating oil to the lubrication and cooling of oil sealing 2.
