Embodiment
Clearer for technical problem, technological scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1 to Figure 3, the utility model provides a kind of retarder, comprising:
End cap 10, described end cap 10 is fixed on retarder, and a side of setting described end cap 10 close retarders is inner side surface, is provided with the gear oil boss 11 that stops lubricant oil on the inner side surface of end cap 10.
The utility model provides a kind of retarder, by be provided with the gear oil boss that stops lubricant oil on the inner side surface of end cap, makes the position that has changed the oil ring that forms on the retarder end cap, and the oil ring position after changing corresponds to and needs the position of lubricating.
Lubricant oil can form oil ring under the effect of centrifugal force on end cap 10 when retarder turns round, the oily boss 11 of described gear is provided with by stopping that lubricant oil changes the gear pasta 12 of oil ring position, lubricant oil on described gear pasta 12 interception end caps, thus the oil ring position changed.Described gear pasta 12 is arc surface or plane or curved surface, and optimum embodiment is arc surface, and first because under centrifugal action, the edge that lubricant oil is got rid of at end cap 10 forms ring-type; Also for circular, arc surface can be corresponding with circle for the entrance (being planet axis blind hole 61 in the present embodiment) at the position that second need to lubricate due to the utility model embodiment, facilitates the entrance that lubricant oil enters needs lubricated position.
The utility model embodiment's retarder is planetary reducer, solve be when planetary reducer when running up, because lubricant oil forms oil ring in end cap edge, make inner bearing 70 be difficult to be lubricated, thus the technical problem of high temperature heating in the running.But in like manner, technical solutions of the utility model also can be used on the other types retarder, be applicable in lubricated other retarders, by changing the height of retarder end cap oil ring, namely the script that arrives of Castor Oil lubricated less than the position; Only need to be according to the concrete structure of other types retarder, change the retarder end cap gear oil boss position, size and highly get final product.
To shown in Figure 5, planetary reducer comprises as Fig. 1:
End cap 10;
Housing 20, described end cap 10 is fixed on housing 20;
Transmit the semiaxis 30 of external torque;
Sun gear 40, described sun gear 40 fixed covers are located at semiaxis 30 outsides;
Planet wheel 50, described planet wheel 50 and sun gear 40 engagements, described planet wheel 50 is fixedly connected with housing 20;
Planet axis 60, described planet wheel 50 are set in planet axis 60 outsides; With
Bearing 70, rolling connects planet wheel 50 and planet axis 60;
Wherein,
The corresponding housing through-hole 21 of exposing planet axis blind hole 61 that is provided with on described housing 20,
Be provided with planet axis blind hole 61 in the middle of planet axis 60, the oily boss 11 of described gear is corresponding with the position of planet axis blind hole 61,
Be provided with the planet axis through hole 62 that at least one is communicated with planet axis blind hole 61 and bearing 70 on the hole wall of planet axis blind hole 61, so that lubricant oil flows out by planet axis through hole 62 from planet axis blind hole 61, and lubricated to bearing 70.
Retarder inside is provided with clamping bolt 80, and the oily boss 11 of described gear is provided with empty avoiding place 13 of avoiding clamping bolt 80, reserves enough spaces for clamping bolt 80.The gear pasta 12 of the oily boss 11 of described gear is corresponding with the position of planet axis blind hole 61, the most preferred embodiment of the correspondence here is: the edge of gear pasta 12 can guarantee better that like this an internal lubrication oil content is fitted in each planet axis blind hole 61 within the profile scope of planet axis blind hole 61.Within can certainly planet axis blind hole 61 being in the profile scope of edge of gear pasta 12.Because under centrifugal action, the edge that lubricant oil is got rid of at end cap 10 forms ring-type, under the barrier effect of the oily boss 11 of gear, lubricant oil on end cap 10 has been blocked in the position of gear pasta 12, then get rid of in the planet axis blind hole 61 corresponding with it by centrifugal force, because planet axis blind hole 61 is blind hole substantially, so be merely able to flow to bearing 70 places, lubricating bearings 70 by planet axis through hole 62.So just in the situation that do not need to increase lubricant oil and other complicated oil circulation systems, the lubricated speed reducer that arrived is not easy the lubricated position of arriving when running up, cause the problem of internal structure quick abrasion.
Retarder end cap 10 no longer adopts traditional stamping process, but adopt the die cast metal technology, can produce like this retarder end cap 10 of the specified structure of more complicated, reach in the situation that do not increase the lubricant oil oil mass, redistribute the position of lubricant oil in retarder inside, thereby strengthen lubrication effect comprehensively, reduce the heating value of retarder inside, simple in structure, substituted the complicated oil circulation system of taking for improving lubrication effect.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
