Abstract
The utility model discloses a thin-wall seamless shaft sleeve, in order to solve the technical problems of low hardness of the surface of a bimetal shaft sleeve, poor wear resistance performance, low tensile strength, rejection due to high probability of deformation under heavy load and high probability of producing defects at the junction of the bimetal shaft sleeve. The adopted technical scheme is that the shaft sleeve comprises a shaft sleeve body with a circulating oil groove and an annular groove, and the key point is that the wall thickness of the shaft sleeve body is 2.0-3.0 mm. The thin-wall seamless shaft sleeve has the beneficial effects that the original bimetal shaft sleeve is integrally subjected to normalizing treatment on the premise that the thin wall characteristic of the original bimetal shaft sleeve is guaranteed, so that the internal stress of steel is removed and the organization of the steel is thinned, the shaft sleeve has the characteristics of high toughness of a basal body and high hardness of the inner surface after the inner surface is subjected to high-frequency quenching treatment, so that the shock resistance and the wear resistance are greatly improved, and after the inner and outer surfaces are vulcanized or phosphated, the friction coefficient is greatly reduced, the premature wear of the shaft sleeve can be avoided and the service life of the shaft sleeve is prolonged.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, relates to a kind of axle sleeve, particularly a kind of thin-wall seamless axle sleeve.
Background technique
In the moving element of machinery, axle sleeve generally plays sliding bearing, existing concrete pump truck joint part generally adopts copper-bimetal copper-steel axle sleeve, and this axle sleeve surface hardness is low, wear-resisting property is poor, tensile strength is low, easily distortion and scrap and bimetallic bush is prone to defective in the joint under heavy duty.
Summary of the invention
The purpose of this utility model is that the bimetallic bush surface hardness is low, wear-resisting property is poor, tensile strength is low in order to solve, easily distortion and scrap and bimetallic bush is prone to the technical problem of defective in the joint under heavy duty, designed a kind of thin-wall seamless axle sleeve in order to address these problems us, Steel material is processed into axle sleeve, and after Overheating Treatment and surface treatment, shock resistance and wear resistance have greatly been improved, decrease friction factor, reduce the rate of wear of axle sleeve, prolonged the working life of axle sleeve.
The utility model for realizing the concrete technological scheme that goal of the invention adopts is: a kind of thin-wall seamless axle sleeve, comprise the sleeve body with circulating oil tank and annular groove, and key is: the wall thickness of sleeve body is 2.0 ~ 3.0mm.
The beneficial effects of the utility model are: make axle sleeve take steel as raw material, process being made into a kind of thin-wall seamless axle sleeve that is applicable to the low-speed heave-load operating mode through whole normalizing, internal surface high frequency hardening, inner and outer surface sulfuration or phosphatization.The internal stress of steel has been removed in whole normalizing, refinement the tissue of steel.After internal surface process high frequency hardening, the temper, make axle sleeve have the characteristic of whole high tenacity, internal surface high hardness, greatly improved shock resistance and wear resistance.Inner and outer surface after over cure or phosphatization are processed, decrease friction factor, can avoid the premature wear of axle sleeve.
Description of drawings
Fig. 1 is sectional drawing of the present utility model.
Fig. 2 is the another kind of embodiment's of the utility model sectional drawing.
In the accompanying drawing, 1 represents sleeve body, and 2 represent circulating oil tank, and 3 represent annular groove, and 4 represent the thrust flange.
Embodiment
A kind of thin-wall seamless axle sleeve comprises that key is: the wall thickness of above-mentioned sleeve body 1 is 2.0 ~ 3.0mm with the sleeve body 1 of circulating oil tank 2 with annular groove 3.
The recycling cross type that is shaped as of above-mentioned circulating oil tank 2.
One end of above-mentioned sleeve body 1 also is provided with thrust flange 4.
The utility model is in the specific implementation: sleeve body 1 is processed by Steel material, and wall thickness is 2.0 ~ 3.0mm.Sleeve body 1 is carried out normalized treatment, and the hardness after the normalizing is 167 ~ 229HB.Internal surface to sleeve body 1 carries out high frequency hardening, temper, is that 0.5 ~ 1.0mm, the effective hardness of quench-hardened case are 45HRC so that internal surface hardness is 52 ~ 60HRC, depth of hardening zone.Inner and outer surface to sleeve body 1 vulcanizes or the phosphatization processing, reduces the friction factor on sleeve body 1 surface, can avoid the premature wear of sleeve body 1.Sleeve body 1 is provided with circulating oil tank 2 and annular groove 3, and they mainly are lubricates, can reduce the friction between sleeve body 1 and the axle, the working life of extending shaft body 1.
As shown in Figure 2, seamless shaft sleeve can also be provided with thrust flange 4 structures, also is provided with thrust flange 4 at an end of sleeve body 1, satisfies the demand of different product.
