Abstract
The utility model relates to a hydro -cylinder earrings with texturing friction is vice, including round pin axle, joint bearing and earrings body, round pin axle and joint bearing's endotheca is a pair of interact's friction pair, and both adopt clearance fit, and there is emollient in clearance china and canada, the texture pattern is processed respectively with the working face of joint bearing's endotheca to the round pin axle, and this utility model can improve on original basis, and texture surface machining reliable and simple, indenture can reduce the actual area of contact on two sides to reduce wearing and tearing, 2 )Lubricating oil can be saved to the indenture, and more untextured friction secondary surface can form the lubricant film more fast, reduces the direct contact of two friction surfaces, takes away the friction production of heat to vice friction and wear reduces friction, 3 )The lubricant film of the lubricating oil formation of indenture storage can provide certain bearing capacity. Simultaneously, the lubricating oil of indenture storage is difficult to run off, also littleer to the consumption of emollient than smooth surface.
Description
Technical field
The utility model relates to technical field of hydraulic pressure, specifically relates to a kind of oil cylinder with texturing friction pair.
Background technique
Oil hydraulic cylinder is in the conventional hydraulic component of engineering machinery.For the oil hydraulic cylinder adopting earrings class to install, be using the bearing pin of earrings as fulcrum and gyration center, oil hydraulic cylinder can swing in the plane perpendicular with earrings bearing pin, therefore will produce the wearing and tearing of earrings internal diameter and bearing pin external diameter.
Research in recent years shows, surface is not more smooth more wear-resisting, but the surface with certain Non-smooth surface form has better wear-resisting property on the contrary.So-called Surface Texture refers to the dot matrix being processed the patterns such as pit, indenture or the convex closure with certain size and arrangement at surface of friction pair by certain processing technique.Surface Texture shows positive effect in the frictional behaviour improving friction pair.
The method of the wearing and tearing of the reduction earrings internal diameter that present stage is commonly used and bearing pin external diameter mainly reduces the surface roughness of both surface of contact, or in earrings, increases axle sleeve for wearing and tearing, and then changes.The former increases difficulty of processing, but effect is not necessarily fine; The latter is a kind of more passive method.
Model utility content
The purpose of this utility model is exactly provide a kind of novel oil cylinder with texturing friction pair for the problems referred to above, this friction pair is lower to requirement on machining accuracy, improve the frictional behaviour of earrings internal diameter and bearing pin external diameter, extend the working life of earrings and bearing pin.
The utility model is realized by following technical measures: a kind of novel oil cylinder with texturing friction pair, comprise bearing pin, joint shaft bearing and earrings body, the inner sleeve of described bearing pin and joint shaft bearing is a pair interactional friction pair, both adopt Spielpassung, are added with oiling agent in gap; The acting surface of the inner sleeve of described bearing pin and joint shaft bearing processes texture pattern respectively.
Described texture pattern is uniform indenture or projection.
The unit figure of described texture pattern is one or more the combination in square, triangle, circle, rectangular or positive six company's shapes.
The texture pattern that the inner sleeve surface Machining of described bearing pin and joint shaft bearing goes out can store oiling agent, can improve its frictional behaviour and bearing capacity, thus increase the service life.
The beneficial effects of the utility model are: 1) can improve on the original basis, and texture surface processing is simple, and indenture can reduce the real contact area on two sides, thus reduce wearing and tearing; 2) indenture can store lubricant oil, and more untextured surface of friction pair can form lubricating film more fast, reduces the direct contact of two rubbing surfaces, takes away that friction generates heat, thus reduces the fretting wear of friction pair; 3) lubricating film that the lubricant oil that indenture stores is formed, can provide certain bearing capacity.Meanwhile, the lubricant oil that indenture stores not easily runs off, also less to the consumption of oiling agent compared with smooth surface.
Accompanying drawing explanation
Fig. 1 is the structural representation of texturing friction pair oil cylinder of the present utility model.
Fig. 2 is the structural representation of joint shaft bearing inner sleeve.
In figure, 1. bearing pin, 2. earrings body, 3. inner sleeve, 4. texture pattern.
Embodiment
In the accompanying drawings, the novel oil cylinder with texturing friction pair, comprises bearing pin 1, joint shaft bearing and earrings body 3, and described bearing pin 1 is a pair interactional friction pair with the inner sleeve 3 of joint shaft bearing, both adopt Spielpassung, are added with oiling agent in gap; Described bearing pin 1 processes texture pattern 4 respectively with the acting surface of the inner sleeve 3 of joint shaft bearing.
Described texture pattern 4 is uniform indenture or projection.
The unit figure of described texture pattern 4 is one or more the combination in square, triangle, circle, rectangular or positive six company's shapes.
The texture pattern 4 that described bearing pin 1 and inner sleeve 3 surface Machining of joint shaft bearing go out can store oiling agent, can improve its frictional behaviour and bearing capacity, thus increase the service life.
