Abstract
The utility model discloses an anti-wear shaft sleeve, which comprises a shaft sleeve body. The shaft sleeve is formed by integral casting. Even protrusions are arranged on the inner wall of the shaft sleeve, and sealing groove are arranged on the inner walls of shaft holes of the front end and the rear end of the shaft sleeve. The anti-wear shaft sleeve is reasonable in surface structure, high in rigidity, good in anti-wear performance and long in service life.
Description
Technical field
The utility model relates to a kind of anti-wear sleeve.
Background technique
Bearing can be divided into rolling bearing and sliding bearing.Wherein rolling bearing is a standard piece relatively more commonly used, has advantages such as friction factor is low, the resistance of start is little, designs, uses, lubricates, safeguards all very convenient.And sliding bearing has certain advantage than rolling bearing when high speed, heavy duty, highi degree of accuracy and bearing structure need subdivision.The characteristics of sliding bearing are bearing capacity height, good anti-vibration, noise is little, the life-span is long.Sliding bearing needs design separately, and material generally is bearing metal (claiming Babbitt again) or bronze.Mostly the axle sleeve of the axle sleeve type sliding bearing that uses at present is to adopt the hollow round column body, and the cylinder internal surface is smooth plane, and this structural type serious wear is scurried on lubricating oil is a large amount of, causes bearing shortening in working life.The main cause that produces above phenomenon is exactly that the axle sleeve inner surface structure of axle sleeve type sliding bearing is unreasonable, and hardness is low, has only Rockwell (HRC) 20-25, and is not wear-resistant.
The model utility content
The utility model provides that a kind of surface structure is reasonable, hardness is high, wear resistance is good, the anti-wear sleeve of long service life.
The utility model technical solution problem provides following scheme:
A kind of anti-wear sleeve comprises the axle sleeve body, and the integrated integral casting forming of said axle sleeve, the inwall of said axle sleeve are provided with uniform salient point respectively.
The inwall of the rear and front end axis hole of said axle sleeve is provided with sealed groove.
The utility model is provided with a plurality of salient points at the internal surface of axle sleeve, and said salient point adopts quenching technical, and making the interior wall tissue of axle sleeve become wear-resisting, hardness can improve greatly, and bump structure helps oil storage, effectively reduces friction.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing, a kind of anti-wear sleeve comprises axle sleeve body 1, and said axle sleeve 1 integrated integral casting forming, the inwall of said axle sleeve 1 are provided with uniform salient point 2 respectively, and the inwall of the rear and front end axis hole of said axle sleeve 1 is provided with sealed groove 3.
Claims (2)
1. an anti-wear sleeve comprises the axle sleeve body, it is characterized in that: the integrated integral casting forming of said axle sleeve, the inwall of said axle sleeve are provided with uniform salient point respectively.
2. according to the said anti-wear sleeve of claim 1, it is characterized in that: the inwall of the rear and front end axis hole of said axle sleeve is provided with sealed groove.
