Abstract
The utility model discloses an oil cave steel bushing, including the steel bushing body, the inner wall of steel bushing body is equipped with a plurality of evenly distributed's crescent oil cave, and the steel bushing body includes tubular body, and tubular body's material is 42CrMo, and tubular body's internal surface is equipped with the carbide wearing layer that forms through thermal treatment, and the surface of carbide wearing layer is equipped with anti -corrosive layer. This oil cave steel bushing adopts crescent oil cave and carries out the oil storage, improves steel bushing body inner wall oil storage area and oil reserve, makes things convenient for the lubrication of axle sleeve.
Description
Technical field
The utility model is related to steel bushing, and in particular to oil pit steel bushing.
Background technology
It is typically necessary in axle sleeve and opens up oil groove, the effect of oil groove is that lubricating oil is injected into sleeve lining, by oil groove
Lubricating oil is delivered to sleeve lining optional position.In the prior art the form of oil groove mainly have " 8 " word oil groove, helical oil groove,
Endless-oil groove, straight oil groove etc..Its oil groove oil reserve is small, should not store, easily loss, and tank structure is uneven, and having much lubricate blind
Area, product lubricates insufficient during use, and quick abrasion is so as to cause product service life short.
The content of the invention
The utility model is regarding to the issue above, there is provided a kind of bigger oil pit steel bushing of oil reserve.
In order to solve the above technical problems, the technical scheme that the utility model is used is：Oil pit steel bushing, including steel bushing sheet
Body, it is characterised in that the inwall of steel bushing body is provided with several equally distributed crescent oil pits, steel bushing body includes tubular sheet
Body, the material of cylindrical body is 42CrMo, and the inner surface of cylindrical body is provided with the carbide wearing layer of thermally treated formation, is carbonized
The surface of thing wearing layer is provided with etch resistant layer.
Used as the preferred of such scheme, the depth capacity of crescent oil pit is 2mm.
The beneficial effects of the utility model are：This oil pit steel bushing carries out oil storage using crescent oil pit, improves steel bushing body
Inwall catchment area and oil reserve, facilitate the lubrication of axle sleeve.
