Abstract
The utility model discloses a wedge strip connecting rod and guide pin bushing connection structure, including wedge strip connecting rod and guide pin bushing, wherein, setting that wedge strip connecting rod runs through in in the guide pin bushing, no oily bush has in the guide pin bushing, do not have oily bush cover install with establishing in outside the wedge strip connecting rod, the utility model discloses increase nos an oily bush in the guide pin bushing, play the ring cover of liner effect, can effectively solve like this because the dead phenomenon of honing main shaft card of wearing and tearing and leading to, increase this bush simultaneously after, this position need not the manual work and beats grease lubrication. Thereby the life -span that effectively reduces maintenance time and increase wedge strip connecting rod.
Description
Technical field
This utility model relates to honing main shaft life-span upgrading field, in particular for a kind of spline connecting rod and guide pin bushing attachment structure.
Background technology
It is generally believed that the mechanism of fretting wear is: the normal pressure between friction surface makes the micro-bulge on surface adhere.Bounding point is cut off by small amplitude motion becomes abrasive dust, and abrasive dust is then oxidized.Oxidized abrasive dust plays a part abrasive particle in wear process, makes friction surface form pit or worm stricture of vagina shape scar.These pits or scar are the roots that stress is concentrated, thus are also the part roots that are subject to dynamic load to lose efficacy.Color according to oxidized abrasive dust, often can be concluded that and whether fretting wear occurs.Iron filings as oxidized take on a red color, and oxidized aluminum bits in black, then will cause abrasion during vibration.The fretting wear having oxidation corrosion phenomenon is denuded also referred to as fine motion.Fretting wear under alternate stress is called that fretting fatigue weares and teares.The reason of fretting wear has following several possibility, the contact of same metal, the similar metal that hardness is very low, the similar metal that hardness ratio is more close, it does not have the metal contact of lubrication.Therefore, solve fretting wear to be particularly important.
Utility model content
In order to solve to occur the problem of fretting wear, this utility model to provide a kind of spline connecting rod and guide pin bushing attachment structure.
For reaching above-mentioned purpose, this utility model provides a kind of spline connecting rod and guide pin bushing attachment structure, including spline connecting rod and guide pin bushing, wherein, what described spline connecting rod ran through is arranged in described guide pin bushing, having oil-free lining in described guide pin bushing, described oil-free lining is installed on outside described spline connecting rod sheathedly.
Above-mentioned spline connecting rod and guide pin bushing attachment structure, wherein, described guide pin bushing is T word pyramidal structure, and described guide pin bushing end is gradually reduced to tail dimension.
Above-mentioned spline connecting rod and guide pin bushing attachment structure, wherein, the axial direction of described guide pin bushing central position offers through hole, and described spline connecting rod is installed in described through hole.
Above-mentioned spline connecting rod and guide pin bushing attachment structure, wherein, described guide pin bushing end edge offers some counterbores, and some described counterbores are relative to central angle angular displacement such as the centers of circle, described guide pin bushing end.
Above-mentioned spline connecting rod and guide pin bushing attachment structure, wherein, also have pin-and-hole in the middle of wherein two counterbores in some described counterbores, installs bearing pin in described pin-and-hole.
Above-mentioned spline connecting rod and guide pin bushing attachment structure, wherein, described oil-free lining includes the first oil-free lining and the second oil-free lining, and two oil-free linings are installed in the through hole of described guide pin bushing, and have distance between the two.
The beneficial effects of the utility model are:
This utility model increases an oil-free lining in guide pin bushing, plays the ring set of liner effect, so can effectively solve due to the stuck phenomenon of the honing main shaft that causes of wearing and tearing, and after increasing this lining, this position lubricates without artificial grease adding simultaneously.Thus effectively reducing maintenance time and increasing the life-span of spline connecting rod.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated:
Fig. 1 is spline connecting rod of the present utility model and the structural representation of guide pin bushing in guide pin bushing attachment structure；
Fig. 2 is spline connecting rod of the present utility model and the side view of guide pin bushing in guide pin bushing attachment structure；
Fig. 3 is spline connecting rod of the present utility model and the structural representation of spline connecting rod in guide pin bushing attachment structure；

Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
Embodiment
Refer to shown in Fig. 1 to Fig. 4, a kind of spline connecting rod of the present utility model and guide pin bushing attachment structure, including spline connecting rod 1 and guide pin bushing 2, wherein, what spline connecting rod 1 ran through is arranged in guide pin bushing 2, assembling effect is as shown in Figure 4, having oil-free lining 3 in guide pin bushing 2, oil-free lining 3 is installed on outside spline connecting rod 1 sheathedly, and oil-free lining 3 includes the first oil-free lining 31 and the second oil-free lining 32, two oil-free linings are installed in the through hole 4 of guide pin bushing 2, and have distance between the two.
This utility model also has implementation below on the basis of the above, continuing with referring to shown in Fig. 1 to Fig. 4,
In further embodiment of the present utility model, guide pin bushing 2 is in T word pyramidal structure, and guide pin bushing 2 end is gradually reduced to tail dimension, and spline connecting rod 1 penetrates from the end of guide pin bushing 2, and afterbody passes.
In further embodiment of the present utility model, the axial direction of guide pin bushing 2 central position offers through hole 4, and spline connecting rod 1 is installed in through hole 4, installs oil-free lining 3 in through hole 4, the size of oil-free lining 3 and spline connecting rod 1 size match, and facilitate the assembly and disassembly of spline connecting rod 1 and guide pin bushing 2.
In further embodiment of the present utility model, guide pin bushing 2 end edge offers some counterbores 5, and some counterbores 5 are relative to central angle angular displacement such as the centers of circle, guide pin bushing 2 end.
In further embodiment of the present utility model, in the middle of wherein two counterbores 5 in some counterbores 5, also there is pin-and-hole 6, pin-and-hole 6 is installed bearing pin 7.
In sum, owing to same metal directly contacts when this utility model connects with guide pin bushing 2 for current spline connecting rod 1, spline connecting rod 1 can be caused to occur abrasion to cause honing main shaft cannot move the problem that stuck phenomenon occurs.Increasing an oil-free lining 3 in guide pin bushing 2, play the ring set of liner effect, so can effectively solve due to the stuck phenomenon of the honing main shaft that causes of abrasion, after increasing this lining, this position lubricates without artificial grease adding simultaneously.Thus effectively reducing maintenance time and increasing the life-span of spline connecting rod.
The foregoing is only this utility model preferred embodiment; not thereby embodiment of the present utility model and protection domain are limited; to those skilled in the art; the equivalent replacement done by all utilization this utility model description and diagramatic content and the obtained scheme of apparent change should be can appreciate that, all should be included in protection domain of the present utility model.
