Abstract
The utility model discloses a shaft sleeve used for a main shaft of a marine supercharger. The shaft sleeve comprises a shaft sleeve body, a coating is arranged on the outer surface of the shaft sleeve body, the hardness of the coating is bigger than the hardness of the shaft sleeve body, and the coating is the graphite-like diamond coating. For the shaft sleeve used for the main shaft of the marine supercharger, as the graphite-like diamond coating is arranged at the outer layer of the shaft sleeve, and the hardness of the coating is higher than HV2000, the hardness of the outer layer of the shaft sleeve is ensured very easily. The shaft sleeve body selects the material with the hardness being lower than that of the main shaft so as to achieve the purpose of protecting the main shaft. The shaft sleeve has long service life and simplified process, causes no damage to the shaft and is mainly used for TET series of supercharges.
Description
Technical field
The utility model relates to the axle sleeve technology, specifically refers to the axle sleeve that pressurized machine main shaft peculiar to vessel is used.
Background technique
In order to protect pressurized machine main shaft peculiar to vessel, on main shaft, be arranged with axle sleeve, sheathed again semifloating bearing on the axle sleeve.Because main shaft costs an arm and a leg,, wish that the hardness of axle sleeve will be lower than the hardness of main shaft, otherwise can aggravate the wearing and tearing of main shaft from the angle of further protection main shaft.And from the interactively of axle sleeve and semifloating bearing, wish that again axle sleeve has suitable hardness.Therefore for the processing of axle sleeve, just formed the contradiction of internal layer and outer different hardness requirement.Usually the processing means are the cure process of the outer surface of axle sleeve being carried out certain form at present; as forming one deck carbon penetration to increase its hardness at sleeve outer surface; also having a kind of means is to quench; but because the thinner thickness of axle sleeve own; though be that outer surface is quenched; also can prolong and internal layer, cause inside and outside hardness that increase is all arranged, unfavorable to the protection of main shaft.
The model utility content
At the prior art above shortcomings, the purpose of this utility model just is to provide a kind of pressurized machine main shaft axle sleeve peculiar to vessel that can effectively solve internal layer and outer different hardness requirement.
To achieve these goals, the technical solution adopted in the utility model is such: pressurized machine main shaft axle sleeve peculiar to vessel, comprise the axle sleeve body, and be provided with the coating of one deck hardness at this external surface of axle sleeve greater than axle sleeve body hardness.
Further, described coating is a class graphite diamond coatings.
The utility model is owing to be provided with class graphite diamond coatings at the axle sleeve skin, and therefore hardness can very easily guarantee outer hardness up to more than the HV2000.The axle sleeve body then selects for use hardness to be lower than the material of main shaft, thereby reaches the purpose of protection main shaft.This axle sleeve life-span is long, and work simplification to not infringement of axle, is mainly used in TET series pressurized machine.
Description of drawings
Fig. 1-the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, as can be seen, the utility model pressurized machine main shaft peculiar to vessel axle sleeve comprises axle sleeve body 1, is provided with the coating 2 of one deck hardness greater than axle sleeve body hardness at axle sleeve body 1 outer surface from the figure.Described coating 2 is a class graphite diamond coatings, and hardness is up to more than the HV2000.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
Claims (2)
1. pressurized machine main shaft axle sleeve peculiar to vessel comprises axle sleeve body (1), it is characterized in that: described axle sleeve body (1) outer surface is provided with the coating (2) of one deck hardness greater than axle sleeve body hardness.
2. pressurized machine main shaft axle sleeve peculiar to vessel according to claim 1 is characterized in that: described coating (2) is a class graphite diamond coatings.
