Description
Technical field
The utility model relates to the full needle bearing lubricating fitting of a kind of lubricating fitting of bearing, particularly a kind of planetary speed reducer.
Background technique
The quality of planet-gear speed reducer is light, velocity ratio is large, bearing capacity is high, and stable drive and transmission efficiency are high, but because its volume is little, the rotating speed of axle is higher, so internal bearings is after rotating for a long time, heating and cooling are slower easily, and too high temperature has directly had influence on the working life of bearing.At present, the planet wheel of planetary speed reducer uses full needle bearing to substitute mostly, because its cost is low, simple in structure, thus be subject to being widely used of people, but full needle bearing heating is fast, so can not further improve its rotating speed, its rotating speed has hindered further developing of it below 1000r/min generally speaking, although there are on the market some full needle bearings to lubricate scheme, but structure is more complicated all, even need special oil supplying device, and increased the cost of equipment, wasted raw material.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of full needle bearing lubricating fitting of simple in structure, lower-cost planetary speed reducer.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of full needle bearing lubricating fitting of planetary speed reducer, at least comprise housing and the epicyclic transmission mechanism that is installed in enclosure interior, described epicyclic transmission mechanism includes sun gear, planet carrier, planet wheel shaft and the full needle bearing that is installed on the planet wheel shaft, lubricant oil is equipped with in lower end in the casing, be fixed with disc on the end face of described planet carrier, disc includes annulus and lower annulus, the edge of two annulus links together by arc transition, it is the annular groove of U-shaped that the inside of the junction of two annulus forms the longitudinal section, the opening of annular groove lower end is positioned at the liquid level of lubricant oil, the outside end face of lower annulus is fixedly connected with the planet carrier end face, described full needle bearing is connected with planet carrier by the planet bearing pin, have axial bore and radial hole in the planet bearing pin, the radial hole two ends link to each other with the inner ring of full needle bearing and the axial bore of planet bearing pin respectively, evenly be provided with at least 3 boss that are set in the planet bearing pin on the outside end face of lower annulus, boss inside offers the through hole that is connected with axial bore in the planet bearing pin.
Lower annulus on the described disc connects by welding, bolt or riveted joint is fixed on the end face of planet carrier.
The position of described boss near lower annulus exterior edge face the edge.
The beneficial effect that the utility model compared with prior art has is: the utility model utilizes disc that the lubricant oil of speed reducer inside is thrown up, oil is transported in the inner ring of full needle bearing by the through hole in the disc, axial bore and radial hole, thereby reach lubricated purpose, therefore can not need to provide lubricated by oil pump or the gear pump of outside, reduced the design difficulty of whole mechanism, simplify the structure of oil supplying device, saved raw material, thereby reduced cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 be disc partly cut open structural representation.
In the accompanying drawing: annulus, 6-annular groove, 7-planet bearing pin, 8-axial bore, 9-radial hole, 10-boss, 11-through hole under 1-planet carrier, the full needle bearing of 2-, 3-disc, the upper annulus of 4-, the 5-.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
A kind of full needle bearing lubricating fitting of planetary speed reducer, with reference to Fig. 1～Fig. 2, at least comprise housing and the epicyclic transmission mechanism that is installed in enclosure interior, described epicyclic transmission mechanism includes sun gear, planet carrier 1, planet wheel shaft and the full needle bearing 2 that is installed on the planet wheel shaft, lubricant oil is equipped with in lower end in the casing, be fixed with disc 3 on the end face of described planet carrier 1, disc 3 includes annulus 4 and lower annulus 5, the edge of two annulus links together by arc transition, it is the annular groove 6 of U-shaped that the inside of the junction of two annulus forms the longitudinal section, the opening of annular groove 6 lower ends is positioned at the liquid level of lubricant oil, the outside end face of lower annulus 5 is fixedly connected with planet carrier 1 end face, described full needle bearing 2 is connected with planet carrier 1 by planet bearing pin 7, have axial bore 8 and radial hole 9 in the planet bearing pin 7, radial hole 9 two ends link to each other with the inner ring of full needle bearing 2 and the axial bore 8 of planet bearing pin 7 respectively, evenly be provided with at least 3 boss 10 that are set in the planet bearing pin 7 on the outside end face of lower annulus 5, boss 10 inside offer the through hole 11 that is connected with axial bore 8 in the planet bearing pin 7.
As preferred version of the present utility model, the lower annulus 5 on the described disc 3 connects by welding, bolt or riveted joint is fixed on the end face of planet carrier 1.The position of described boss 10 near lower annulus 5 exterior edge faces the edge.
