Abstract

The invention discloses a split type gear pump floating shaft sleeve combination piece and a machining method thereof. The split type gear pump floating shaft sleeve combination piece is good in machining process, and the product quality is easily guaranteed. The split type gear pump floating shaft sleeve combination piece comprises cylindrical shaft sleeves with circular flanges, a plane parallel to a shaft hole is manufactured on each flange, and floating shaft sleeves are manufactured; a sliding bearing made of composite materials is installed in the shaft hole of each floating shaft sleeve, a steel sleeve is arranged outside each sliding bearing, and copper alloyed powder layers are sintered on the inner walls of the steel sleeves; and Teflon layers are attached to the copper alloyed powder layers, and the planes of the two floating shaft sleeves are oppositely combined to form a floating shaft sleeve combination piece shaped like an Arabic numeral eight. According to the whole floating shaft sleeve combination piece shaped like the Arabic numeral eight, the two split floating shaft sleeves are combined, and therefore the machining accuracy and the production efficiency of the floating shaft sleeve are greatly improved.

Description

Detachable gear wheel pump floating buss assembly parts and processing method thereof
Technical field
The present invention relates to the part of gear pump, particularly relate to and be a kind ofly applied to the split type floating buss assembly parts of high-pressure gear pump and processing method thereof.
Background technique
Gear pump is part conventional in hydraulic system, and it relies on the swept volume formed between the pump housing and engaging gear to change and the mobile rotary pump carried liquid or make it supercharging.It is by two meshed gears and to be close to gear both ends of the surface be that the floating buss of 8-shaped forms two closed spaces as shown in Figure 1.Axle on two gears, is inserted in the floating axle trepanning of 8-shaped.When pinion rotation, the volume in the space, side that is out of gear is large from little change, forms vacuum, is sucked by liquid, and liquid from diminishing greatly, and is clamp-oned in pipeline and gone by the spatial volume of gears meshing side, forms High voltage output.Integrated type is all adopted to process at floating buss conventional at present, by the floating buss overall processing of 8-shaped, two gear shaft holes up and down of processing 8-shaped, the both ends of the surface of axis hole, and the technological method of this overall processing, when processing two gear shaft holes, need secondary clamping, the part of this 8-shaped profile is irregular shape, general fixture can not use, and provide the profile of clamping parts 8 word to be non-finished surface, after secondary clamping, the tolerance of size of part and the precision of positioning tolerance are difficult to ensure, its precision of vital part as gear pump is very high again, usually in 5-6 level, therefore higher by traditional method processing reject rate, the quality of product is difficult to control always.
Summary of the invention
The object of the present invention is to provide a kind of structure is simple, technology capability good, quality of product easily ensures detachable gear wheel pump floating buss assembly parts and processing method thereof.
In order to reach above-mentioned requirements, technological scheme of the present invention: it is characterized in that it comprises the cylinder-shaped sleeve of band circular flange, flange is shaped with a plane parallel with axis hole, make floating buss, the sliding bearing rolled into composite material is installed in the axis hole of floating buss, described sliding bearing ecto-entad is steel bushing successively, the inwall sintering of steel bushing has Cuprum alloy bisque, alloyed copper bisque is attached with polytetrafluoroethylene floor, the floating buss assembly parts of the plane involution composition 8-shaped of two floating busses.
Spirality or 8-shaped or the oil groove straight with axis being parallel is shaped with in the endoporus of described sliding bearing.
The processing method of described floating buss: with bar or tubing, lathe clamps blank cylindrical with common three jaw chuck and passes through clamped one time, machine the cylindrical of floating buss, endoporus, flange and end face, making centre has axis hole, and outer rim has the axle sleeve of flange; With axis hole location on milling machine, on flange, Milling Machining goes out the plane parallel with axis hole.
By the floating buss assembling unit structure of such scheme by original integrated type 8-shaped, the floating buss split type by two pieces combines, adopt split type structure, adding man-hour, plane can be reprocessed after clamped one time machines at the internal diameter of floating buss, external diameter, flange and end face, so just substantially increase the machining accuracy of floating buss, and be applicable to automation processing, manufacturing efficiency also can improve greatly.Sliding bearing is owing to making with composite material volume, its matrix is steel bushing, good rigidly, makes above the good polytetrafluoroethylene floor of wear resistance is attached to, to substantially increase the wear resistance of gear pump floating buss assembly parts axis hole and the working life of gear pump by alloyed copper bisque.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 2 to Fig. 4 is the structural representation of detachable gear wheel pump floating buss assembly parts.As seen from the figure, it comprises the cylinder-shaped sleeve of band circular flange 1, flange 1 is shaped with a plane 3 parallel with axis hole 2, make floating buss 4, the sliding bearing 5 rolled into composite material is installed in the axis hole 2 of floating buss 4, described sliding bearing 5 ecto-entad is steel bushing 6 successively, the inwall sintering of steel bushing 6 has Cuprum alloy bisque 7, alloyed copper bisque 7 is attached with polytetrafluoroethylene floor 8, in the endoporus of sliding bearing 5, is shaped with the oil groove 9 straight with axis being parallel of spirality or 8-shaped.The plane 3 of two floating busses 4 is to being combined into the floating buss assembly parts of 8-shaped as shown in Figure 5.
The processing method of described floating buss 4: with bar or tubing, lathe clamps blank cylindrical with common three jaw chuck and passes through clamped one time, the cylindrical of floating buss, endoporus, flange 1 and end face are machined, make centre and have axis hole 2, outer rim has the axle sleeve of flange 1 as shown in Figure 6, Figure 7; Milling machine is used the excircle orientation of axis hole 2 or floating buss 4, flange 1 processes the plane 3 parallel with axis hole 2, makes floating buss 4 as shown in Figure 2 and Figure 3.
