Abstract
The utility model relates to a spline lubricating structure, including preceding oil baffle disc, back oil baffle disc, jump ring, fuel sprayer, preceding oil baffle disc and back oil baffle disc for ring shape, the setting is at the both ends of external splines respectively to it is fixed through the jump ring, preceding oil baffle disc is provided with annular with the back oil baffle disc is upper in the spline position of engagement, and the inboard of preceding oil baffle disc sets up the toper ring to the terminal surface of external splines forms the toper oil storage tank, is provided with the oil -out on the annular on the back oil baffle disc, and the oil spout orientation of oil spout faces the toper oil storage tank. The utility model discloses each section mating surface that can ensure all splines has sufficient lubricating oil to make the spline wear problem obtain very big improvement, guaranteed the life of input shaft spline.
Description
Technical field
This utility model relates to a kind of lubrication system, especially a kind of spline lubricating structure.
Background technology
In machine driven system, spline is used to one of usual way carrying out moment of torsion transmission.Owing to device is manufacturing the reason installing equal error, spline may work under conditions of axis deviation, cause existing between the spline flank of tooth being meshed relatively sliding, abrasion it is susceptible to, it is therefore desirable to ensureing sufficient lubrication, current existing structure is to arrange oil groove in the middle part of spline after work, 6 oilholes evenly distributed in the circumferential direction in oil groove, the lubricating oil spraying into power shaft endoporus is flowed into oil groove by these oilholes, then is lubricated, as shown in Figure 1 to the flowing of both sides splined surfaces.The lubricating oil that the lubrication of this structure only enters by 6 oilholes is carried out, it cannot be guaranteed that all of spline engagement part is lubricated, the lubricating oil amount simultaneously entered is less, and sometimes it cannot be guaranteed that lubrication in spline whole tooth length, frequently result in spline two ends to wear and tear, it is impossible to meet service life.
Summary of the invention
The purpose of this utility model provides a kind of spline lubricating structure, it is ensured that is lubricated the whole tooth length of all splines, meets the service life of spline.
Technical solutions of the utility model are, spline lubricating structure includes front oil baffle disc, rear oil baffle disc, jump ring, atomizer, described front oil baffle disc and rear oil baffle disc are annular, are separately positioned on the two ends of external splines, and fix by being arranged on two jump rings at internal spline two ends；Front oil baffle disc and the upper annular groove being provided with annular in spline engagement position of rear oil baffle disc, the inner side of described front oil baffle disc arranges the cone-shaped ring that oriented axis direction extends, described cone-shaped ring forms taper oil storage tank with the end face of external splines, described taper oil storage tank communicates with the annular groove of front oil baffle disc, the oil-out communicated with outside it is provided with on the described annular groove on rear oil baffle disc, described atomizer is positioned at front oil baffle disc side, and the oil spout direction of atomizer faces taper oil storage tank.Described annular groove is wide 2mm, the rectangular channel of deep 1.4mm, and described oil-out is uniform 12, a diameter of φ 1.2mm.
This utility model is oil baffle disc and rear oil baffle disc and annular groove before spline two ends devise, and defines annular oil cavity, and annular oil cavity covers whole mate, it is possible to achieve overall lubrication；Cone-shaped ring forms oil storage tank with external splines end face, the substantial amounts of lubricating oil from nozzle ejection can be stored, thus ensure that enough lubricating oil enter site of engagement and are lubricated, simultaneously, the oil-out of rear oil baffle disc design, vent plug can be eliminated, it is possible to make lubricating oil fully flow, it is ensured that clean lubricating oil enters into the position needing lubrication.This utility model may insure that each section of field of conjugate action of all of spline has the lubricating oil of abundance, so that spline wear problem is greatly improved, it is ensured that the service life of power shaft spline.

Fig. 1 is common spline lubricating structure schematic diagram.
Fig. 2 is structural representation of the present utility model；
Fig. 3 is the partial enlarged drawing of Fig. 2.
Detailed description of the invention
As it can be seen, spline lubricating structure includes that front oil baffle disc 1, rear oil baffle disc 2, jump ring 3, atomizer, described front oil baffle disc 1 and rear oil baffle disc 2 are annular, it is separately positioned on the two ends of external splines, and fixes by being arranged on two jump rings 3 at internal spline two ends；It is positioned at spline engagement position on front oil baffle disc 1 and rear oil baffle disc 2 and is provided with the annular groove 4 of annular, the inner side of described front oil baffle disc 1 arranges the cone-shaped ring 5 that oriented axis direction extends, described cone-shaped ring 5 forms taper oil storage tank 6 with the end face of external splines, described taper oil storage tank 6 communicates with the annular groove 4 of front oil baffle disc, the oil-out communicated with outside it is provided with on the described annular groove on rear oil baffle disc 2, described atomizer is positioned at front oil baffle disc 1 side, and the oil spout direction of atomizer faces taper oil storage tank 6.Described annular groove 4 is wide 2mm, the rectangular channel of deep 1.4mm, and described oil-out is uniform 12, a diameter of φ 1.2mm.
