Abstract
The utility model discloses a hydraulic gear pump shaft sleeve cast by a double-layer alloy, consisting of a substrate(1) and a surface alloy layer(2), wherein, the side close to the gear on the substrate(1) is attached with the surface alloy layer(2) which is a low tin-aluminium alloy, a tin bronze or other wearable alloy, while the substrate(1) is a high intensity aluminium alloy or other alloy; besides, by metal mould casting and pressing casting, the surface alloy layer(2) is wholly attached to the substrate(1), forming the shaft sleeve. Achieving a reasonable matching material function by use of different alloy layers, the utility model ensures the operation performance of the shaft sleeve, and meantime, reduces the production cost of the shaft sleeve, improving the economic benefit.
Description
Technical field
The utility model relates to the hydraulic gear pump axle sleeve, is specifically related to the hydraulic gear pump axle sleeve of double-layer alloy casting.
Background technique
The most employing of hydraulic gear pump axle sleeve adds the DU bearing structure both at home and abroad at present, and the matrix of axle sleeve is low-tin aluminium alloy or other abrasion resistance alloys of individual layer, because the rise of raw metal price, cost of production increases thereupon, has reduced productive profit.
Summary of the invention
The purpose of this utility model is: provide a kind of hydraulic gear pump axle sleeve of double-layer alloy casting, the cost of production when guaranteeing the axle sleeve usability behind the reduction axle.
Technical solution of the present utility model is: this axle sleeve is made of matrix and surface alloying layer, on matrix, lean on gear side attaching surface alloy-layer, surface alloying layer is low-tin aluminium alloy, tin bronze or other abrasion resistance alloys, matrix is high tensile aluminium alloy or other alloys, the whole axle sleeve of forming of attaching surface alloy-layer on matrix by die cast and extrusion casint.
The utility model reaches the material function coupling rationally by the different-alloy layer, guarantees the axle sleeve usability, reduces the axle sleeve cost of production simultaneously, increases economic efficiency.
Description of drawings
Fig. 1 is the utility model axle sleeve structure sectional view.
Among the figure: 1. matrix, 2. surface alloying layer.
Embodiment
As shown in Figure 1, this axle sleeve is made of matrix 1 and surface alloying layer 2, on matrix 1, lean on gear side attaching surface alloy-layer 2, surface alloying layer 2 is low-tin aluminium alloy, tin bronze or other abrasion resistance alloys, matrix 1 is high tensile aluminium alloy or other alloys, the attaching surface alloy-layer 2 whole axle sleeves of forming on matrix 1 by die cast and extrusion casint.
Claims (1)
1. the hydraulic gear pump axle sleeve of double-layer alloy casting, it is characterized in that: this axle sleeve is made of matrix (1) and surface alloying layer (2), go up by gear side attaching surface alloy-layer (2) formation at matrix (1), surface alloying layer (2) is low-tin aluminium alloy, tin bronze or other abrasion resistance alloys, matrix (1) is high tensile aluminium alloy or other alloys, goes up the whole axle sleeve of forming of attaching surface alloy-layer (2) by die cast and extrusion casint at matrix (1).
