Abstract
The utility model relates to a there is not oily vortex air compressor, include: the casing body, the casing body including first bearing mounting hole, second bearing mounting hole and the third bearing mounting hole of installing three crank axles respectively, first bearing mounting hole, second bearing mounting hole and third bearing mounting hole be processed into the through -hole, the terminal surface in three hole is a plane, the beneficial effects of the utility model are that: because bearing axial positioning face be a plane, thus can guarantee three bearing mounting hole positioning end face coplane degree more easily through a milling process completion, very big simplification manufacturing procedure.
Description
Technical field
The utility model relates to a kind of oil-free vortex air compressor, particularly relates to the bearing mounting hole of the housing of this machine.
Background technique
Oil-free vortex air compressor is that one utilizes scroll machine principle to obtain compressed-air actuated machinery.Its operation characteristic is that orbiter does revolution translation around fixed scroll under live axle drives, and orbiter can not rotate around oneself geometrical center (namely dynamic scrollwork can not produce rotation).As shown in Figure 1, three-crankshaft (201,202,203) structure is a kind of structure most widely used in oil-free vortex air compressor in anti-Self-rotation structure.
Three-crankshaft one end is fixed on dynamic scrollwork, and one end is fixed on housing, thus namely three-crankshaft ensures orbiter not rotation, also forms axially support to orbiter.In order to ensure that orbiter is parallel with the axial end of fixed scroll, the axial end locating face of three bent axles should be coplanar.
Prior art design proposal is that three bearing mounting hole end faces are processed respectively, locating face is realized coplanar by the Control Shaft bearing bore degree of depth, because three bearing mounting holes are processed respectively, the whole course of working of inevitable requirement and equipment have very high repetitive positioning accuracy, and course of working is comparatively complicated.
Summary of the invention
The utility model technical issues that need to address there is provided a kind of bearing support of oil-free vortex air compressor, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: enclosure body; Described enclosure body comprises clutch shaft bearing mounting hole, the second bearing mounting hole and the 3rd bearing mounting hole of installing three crankshafts respectively; Described clutch shaft bearing mounting hole, the second bearing mounting hole and the 3rd bearing mounting hole are processed into through hole, and the end face in three holes is a plane.
Compared with prior art, the beneficial effects of the utility model are: because bearing axial locating surface is a plane, so can be completed by a Milling Process, more easily ensure three bearing mounting hole location end face coplane degrees, greatly simplify manufacturing procedure.
Accompanying drawing explanation
Fig. 1 is the cross-sectional distribution figure of three three crankshafts.
Fig. 2 is the utility model through-hole structure schematic diagram.
Fig. 3 adopts scheme of installation of the present utility model (sectional drawing of bent axle 2 and 3).
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: enclosure body 4; Described enclosure body 4 comprises clutch shaft bearing mounting hole 101, second bearing mounting hole 102 and the 3rd bearing mounting hole 103 of installing three crankshafts respectively; Described clutch shaft bearing mounting hole 101, second bearing mounting hole 102 and the 3rd bearing mounting hole 103 are processed into through hole, and the end face in three holes is a plane.
As seen from Figure 3: the second bent axle 1 is installed in the second bearing mounting hole of housing 4 by clutch shaft bearing 6 and the second bearing 7, clutch shaft bearing 6 and the second bearing 7 are axially positioned on the first end face 3 and the second end face 5 of housing 4, at the first end face 3 place, fixed by clutch shaft bearing end cap 2, at the second end face 5 place, fixed by bearing support 8.With the second bent axle 1, three-crankshaft 14 is installed in the 3rd bearing mounting hole of housing 4 by the 3rd bearing 9 and the 3rd bearing 10,3rd bearing 9 and the 4th bearing 10 are axially positioned on the 3rd end face 11 and the 4th end face 12 of housing 4, at the 3rd end face 11 place, fixed by the second bearing (ball) cover 13, at the 4th end face 12 place, fixed by bearing support 8.
Bearing mounting hole is designed to through hole by housing 4 of the present utility model, make the first end face 3 and the second end face 5 is actual becomes same plane, process at one time, thus when avoiding non through hole design, originally required that the first end face 3 of coplane degree and the second end face 5 needed at least twice processing: namely add man-hour, setting program first processes the first end face 3, and after completing, needs are griffed, after moving to the second end face 5, then carry out the processing of the second end face 5.Equally, the 3rd end face 11 and the 4th end face 12 also become same plane.
The utility model is by being designed to through hole by bearing mounting hole, and simplifying multiple end face is a plane, reduces the required precision of process equipment, improves efficiency.
