Abstract
The utility model relates to a shaft sleeve, and the shaft sleeve is provided with a steel outer sleeve (1) and an aluminum zinc alloy inner sleeve (2) which is inserted in the steel outer sleeve (1); a spiral oil groove (3) and an oil groove (4) are arranged in the hole of the aluminum zinc alloy inner sleeve (2), and the shaft sleeve is characterized in that two ends of the inner hole of the aluminum zinc alloy inner sleeve (2) are provided with sealing grooves (5).
Description
Technical field
The utility model belongs to the adapting device of the mechanical axis that uses in the middle of a kind of engineering machinery, and definite saying is a kind of axle sleeve.
Background technique
For the axle sleeve that uses in the engineering machinery, particularly the axle sleeve use amount of aluminium alloy material is very big, but because the characteristic of aluminium alloy material itself is crisp, improper often chipping owing to installing when assembling, have influence on normal installation and use, and the price of present allumen is going up always, has also increased manufacturing cost and use cost for no reason.In order to address this problem, designer of the present utility model has done research in earnest, has proposed goal of the invention of the present utility model.
Summary of the invention
Goal of the invention of the present utility model is in order to overcome at present because the crisp characteristic of aluminium alloy material itself, improper often chipping owing to installing when assembling, have influence on normal installation and use, and, the price of present allumen is going up always, has also increased problem and shortage such as manufacturing cost and use cost for no reason and has put forward.
Technical solution of the present utility model is to realize like this, this axle sleeve has a steel sleeve [1] and closely is set in cover [2] in the interior allumen of steel sleeve [1], in the hole of the interior cover [2] of allumen, have helical oil groove [3] and oil groove [4], it is characterized in that the endoporus two ends of cover [2] in allumen have seal groove [5].
Beneficial technical effects of the present utility model is: easy damaged problem when this axle sleeve has overcome crisp installation of original simple Zinc-Aluminium alloyed axle sleeve quality, and, after seal groove has been designed at two ends, make the friction pair between axle sleeve and the axle journal be able to good sealing, avoided because Environmental Conditions is abominable, enter the silt dust in the friction pair easily, and the axle that causes and the wear out failure of axle sleeve, improved the durability of friction pair, owing to adopted the overcoat of steel structure, saved a large amount of aluminium alloy materials, thereby reduced manufacturing cost and use cost simultaneously, only with regard to this axle sleeve, purer allumen cost can be saved 20%-40%.
Description of drawings
Accompanying drawing is a structural profile schematic views of the present utility model.Sequence number in the accompanying drawings is described as: 1, steel sleeve, 2, cover in the allumen, 3, helical oil groove, 4, oil groove, 5, seal groove.
Embodiment
Below in conjunction with the embodiment who provides in the accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, this axle sleeve has a steel sleeve [1] and closely is set in cover [2] in the interior allumen of steel sleeve [1], should inlaying of interior overcoat can adopt interference fit to heat the method realization of installation then, and also can adopt transition fit, the method for the assembling of colding pressing makes it to become one.Have helical oil groove [3] and oil groove [4] in the hole of the interior cover [2] of allumen, this oil groove also can adopt for example oil groove of figure of eight structure of other suitable structure shape.And its basic distinguishing characteristics is, the endoporus two ends of cover [2] have seal groove [5] in allumen, and the rubber seal of packing in the sealing groove is isolated so that axle sleeve inside is carried out, avoided the operation place inclement condition owing to engineering machinery, impurity such as dust silt enter into the inside of axle sleeve.Start with to the seal groove two sides from steel sleeve and to have improved reliability.
