Abstract

The utility model relates to an automatic lubricating device for a planetary gear bearing. In prior art, the planetary gear bearing is lubricated in two ways, that is, the planetary gear bearing is lubricated from the outer side in the low speed transmission process by means of oil impregnation or oil splash, but this lubrication method is unreliable; and additionally, the planetary gear bearing is lubricated by a pressure oil which is guided from ducts on the planet wheel rack and the planet wheel axle in the high speed heavy duty transmission process, but the structure is complicated. The planet wheel axle is projecting out of the planet wheel rack and is provided with a notch; an axial oil duct and a radial oil duct are arranged in the planet wheel axle; one end of the axial oil duct is communicated with the bottom of the notch and the other end is communicated with the radial oil duct; and the outlet of the radial oil duct is arranged at a gap between two flange bearings, thus forming the automatic lubricating device for the bearing. Compared with the lubrication method of oil impregnation or oil splash, the utility model has high lubrication reliability, and has simple structure in comparison to the pressure oil forced lubrication method.

Description

A kind of automatic lubricator of planet wheel bearing
Technical field
The utility model relates to retarder, gyrator, is a kind of automatic lubricator of planet wheel bearing specifically.
Technical background
In the prior art, the lubricated of planet wheel bearing often taked dual mode: often planet wheel bearing is lubricated from the outside by immersing oil sump or fluid being splashed in the low speed transmission, there is lubricated insecure shortcoming in this mode; In the transmission of high-speed overload, reliably often adopt pressure oil lubricated for making to lubricate, promptly pressure oil to be guided to the planet wheel bearing place and be lubricated by laying duct on planetary wheel carrier and planet wheel shaft, its distinct disadvantage is complexity of structure.
The model utility content
The technical problem that the utility model solved provides a kind of self oiling of adopting simple structure to realize the planetary gear train bearing, the bearing automatic lubricator of the planetary gear train of reliable operation.
For solving above-mentioned technical problem, the technological scheme that the utility model is taked:
The utility model comprises planetary wheel carrier, location baffle ring, planet wheel, planet wheel shaft, planet wheel shaft is arranged on the planetary wheel carrier, and by baffle ring location, location, planet wheel is set on the planet wheel shaft, be provided with bearing between the two, be provided with between bearing and the planetary wheel carrier and adjust packing ring, circlip for hole, gasket ring, constitute planetary gear train, it is characterized in that: described planet wheel shaft is given prominence to outside planetary wheel carrier and is provided with breach; Be provided with axial oil duct and radial direction oil in the described planet wheel shaft, axially an end of oil duct communicates with the bottom of breach, and the other end communicates with radial direction oil, and the outlet of radial direction oil is arranged on the gap between the two dish bearings, constitutes the bearing automatic lubricator.
The breach of above-mentioned planet wheel shaft is the bowl type, and its direction is consistent with the line of motion velocity attitude of planet wheel shaft, and locatees in a circumferential direction by the location baffle ring.
The boring of above-mentioned axial oil duct is sealed by plug at the opening of axle head.
Compared with prior art, the beneficial effects of the utility model:
The utility model is compared with immersion oil or splash lubrication, and lubricating reliability improves; Compare with the pressure oil pressure lubrication, have advantage of simple structure.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to sectional view;
Among the figure: 1, sun gear, 2, planetary wheel carrier, 3, the location baffle ring, 4, adjust packing ring, 5, circlip for hole, 6, gasket ring, 7, planet wheel, 8, bearing, 9, planet wheel shaft, 10, sprue, 11, axial oil duct, 12, radial direction oil.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1, the utility model comprises planetary wheel carrier 2, location baffle ring 3, planet wheel 7, planet wheel shaft 9, planet wheel shaft 9 is arranged on the planetary wheel carrier 2, and by location baffle ring 3 location, planet wheel 7 is set on the planet wheel shaft 9, is provided with bearing 8 between the two, is provided with between bearing 8 and the planetary wheel carrier 2 to adjust packing ring 4, circlip for hole 5, gasket ring 6, constitute planetary gear train, planet wheel shaft 9 is given prominence to outside planetary wheel carrier 2 and is opened a gap; Be provided with axial oil duct 11 and radial direction oil 12 in the described planet wheel shaft 9, axially an end of oil duct communicates with the bottom of breach, the other end communicates with radial direction oil 12, and the outlet of radial direction oil 12 is arranged on the gap between the two dish bearings 8, constitutes the bearing automatic lubricator.
Referring to Fig. 2, the breach of planet wheel shaft 9 is the bowl type, and its direction is consistent with the line of motion velocity attitude of planet wheel shaft 9, and locatees in a circumferential direction by location baffle ring 3.
Axially the boring of oil duct 11 is sealed by plug 10 at the opening of axle head, makes it only to communicate with bowl-type breach bottom.
When planetary gear train is worked, the bowl-type breach is collected in the fluid that runs in its movement process (in the oil sump or splash), owing between the fluid of planet wheel shaft 9 and collection very high speed of related movement is arranged, according to principle of hydrodynamics, the original kinetic energy of fluid that falls into the bowl-type breach can change into the pressure energy, offer runner in planet wheel shaft 9 inside with bowl-type breach bottom and bearing portion UNICOM, will form one oil stream, incessantly bearing is carried out self oiling.
