It includes the cylindrical shaft cover of taking circular flange, and the system has a plane parallel with the shaft hole on the flange, makes unsteady axle sleeve, installs the slide bearing who makes with the combined material book in the shaft hole of axle sleeve of floating, slide bearing outside -in is the steel bushing in proper order, and the inner wall sintering of steel bushing has a copper alloy bisque, and it has the polytetrafluoroethylene layer to adhere to on alloy copper powder layer, the floating axle cover sub -assembly of plane to setting up into 8 fonts jointly of two unsteady axle sleeves. The utility model discloses a with the floating axle of 8 integral fonts cover sub -assembly structure, by two split type floating axles cover combinations, adding man -hour, can be at internal diameter, external diameter, flange and the terminal surface of the axle sleeve that floats machining plane, machining precision and production efficiency with regard to having improved unsteady axle sleeve greatly so again after a clamping processing is accomplished.
Description
Technical field
This utility model relates to the part of gear pump, particularly relates to and a kind of is applied to the floating buss molectron that high-pressure gear pump is split type.
Background technology
Gear pump is part conventional in hydraulic system, and the swept volume that it is dependent on being formed between the pump housing and meshing gear changes and moves carries liquid or so as to the drum pump of supercharging.It is formed two spaces closed by two meshed gears as shown in Figure 1 with being close to the floating buss that gear both ends of the surface are 8-shaped.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 big from little change, forms vacuum, draws liquid into, and the spatial volume of gear engagement side is from diminishing greatly, and is clamp-oned by liquid in pipeline, forms High voltage output.Monoblock type is all adopted to process at floating buss conventional at present, floating buss overall processing by 8-shaped, two gear shaft holes up and down of processing 8-shaped, the both ends of the surface of axis hole, and the process 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 the profile providing clamping parts 8 word is non-finished surface, after secondary clamping, the dimensional tolerance of part and the precision of position of related features are difficult to ensure that, its precision of vital part as gear pump is significantly high again, generally in 5-6 level, therefore higher by traditional method processing percent defective, the quality of product is difficult to control to always.
Utility model content
The purpose of this utility model is in that to provide the detachable gear wheel pump floating buss molectron that a kind of simple in construction, processing technology be good, product quality is easily guaranteed that.
In order to reach above-mentioned requirements, the technical solution of the utility model: it is characterized in that it includes the cylinder-shaped sleeve with circular flange, flange is shaped with a plane parallel with axis hole, make floating buss, the axis hole of floating buss is provided with the sliding bearing rolled into composite, described sliding bearing ecto-entad is steel bushing successively, the inwall sintering of steel bushing has copper alloy bisque, alloyed copper bisque is attached with polytetrafluoroethylene floor, the floating buss molectron of the plane involution composition 8-shaped of two floating busses.
The endoporus of described sliding bearing is shaped with spiral type or 8-shaped or the oil groove with axis straight parallel.
By the such scheme floating buss assembling unit structure by original monoblock type 8-shaped, the floating buss combination split type by two pieces, 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, thus substantially increasing the machining accuracy of floating buss and the processing of applicable automatization, production efficiency also can be greatly improved.Sliding bearing is owing to making with composite volume, its matrix is steel bushing, good rigidly, makes the good polytetrafluoroethylene floor of wearability be attached to above by alloyed copper bisque, substantially increases the wearability of gear pump floating buss molectron axis hole and the service life of gear pump.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 2 to Fig. 4 is the structural representation of detachable gear wheel pump floating buss molectron.As seen from the figure, it includes the cylinder-shaped sleeve with circular flange 1, flange 1 is shaped with a plane 3 parallel with axis hole 2, make floating buss 4, being provided with the sliding bearing 5 rolled into composite in the axis hole 2 of floating buss 4, described sliding bearing 5 ecto-entad is steel bushing 6 successively, and the inwall sintering of steel bushing 6 has copper alloy bisque 7, alloyed copper bisque 7 is attached with polytetrafluoroethylene floor 8, the endoporus of sliding bearing 5 is shaped with the oil groove 9 with axis straight parallel of spiral type or 8-shaped.The plane 3 of two floating busses 4 is to being combined into the floating buss molectron 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 scroll chuck and passes through clamped one time, the cylindrical of floating buss, endoporus, flange 1 and end face are machined, and making centre has axis hole 2, and outer rim has the axle sleeve of flange 1 as shown in Figure 6, Figure 7；With the excircle orientation of axis hole 2 or floating buss 4 on milling machine, flange 1 processes the plane 3 parallel with axis hole 2, makes floating buss 4 as shown in Figure 2 and Figure 3.
