Fig. 2 is the schematic cross section of a kind of fastening blade-type rotary compressor shown in Figure 1.

Embodiment

Fig. 1 and Fig. 2 show an embodiment's of a kind of fastening blade-type rotary compressor of the utility model longitudinal section schematic representation and schematic cross section.In this embodiment, described fastening blade-type rotary compressor comprises that 1, one of a rotor that cylindrical outer surface arranged has 2, one columniform rotary columns 3 of rotating sleeve of circle hole shape inner hole surface, 4, one fixed frames 5 of the isolated blade of a flat and a housing 6; Rotor 1 adopts cantilever structure, and its lower end is made axle journal 7 and cooperated with bearing 8, and bearing 8 can be that sliding bearing (as shown in Figure 1) also can be the rolling bearing (not shown), and rotor 1 and axle journal 7 be totally one axes O 1; The axes O 2 of rotating sleeve 2 inner hole surface is parallel with the axes O 1 of rotor 1, and the outer surface of its inner hole surface and rotor 1 rotates contact matching, can have oil film to exist in its cooperation place; The two ends of rotating sleeve 2 are located respectively and are fastened with servo-actuated

end cap

9a and 9b, wherein the center portion of servo-actuated end cap 9a is extended and is made rotating shaft 9c (as shown in Figure 1), perhaps rotating shaft 9c is made the back separately and fasten as one with servo-actuated end cap 9a, they have identical implication in this example; The axis of rotating shaft 9c is coaxial with the axes O 2 of rotating sleeve 2 inner hole surface, axes O 2 and axes O 1 layouts that be parallel to each other, and both allow certain deviation to adapt to manufacturing and alignment error; Rotating shaft 9c supports by bearing 10a and bearing 10b, bearing 10a and bearing 10b are arranged in the same side of rotor 11, they can be that rolling bearing (as shown in Figure 1) also can be the sliding bearing (not shown), can be installed in jointly that (fixed frame 5 as shown in Figure 1) also can be installed in (not shown) on the different parts respectively on the same support; Rotor 11 is installed in the top of rotating shaft 9c and drives rotating shaft 9c and rotates, and in the present embodiment, rotor 11 adopts the up-set type layout; Through hole is made in the center portion of servo-actuated end cap 9b, so that allow the axle journal 7 of rotor stretch out; The direction of O1 of paralleling to the axis in rotor 1 upper edge offers arc groove 12, and rotary column 3 is fitted in this arc groove 12 and is rotatably assorted with it, rotary column 3 and arc groove 12 coaxial line O3; The direction of O3 of paralleling to the axis in rotary column 3 upper edges offers flat chute 13, and its optimum position is to offer along the radial orientation of rotary column; Isolated blade 4 arranges that along the direction of the O2 that parallels to the axis its optimum position is to settle along the radial orientation of rotating sleeve 2; The inner of isolated blade 4 is inserted in the flat chute 13 and is slidingly matched with it, and the outer end of isolated blade 4 is fastened on the endoporus wall of rotating sleeve 2; In the present embodiment, rotor 1 adopts the underneath type layout, and the underpart of its axle journal 7 puts in the housing 6 formed oil sumps, is furnished with lubrication oil supply device and oil duct on the rotor, wherein oil duct can be offered along the axial direction of rotor 1, and its lubricating fitting also can adopt other common forms certainly.Need to prove, in the present embodiment, on the rotor 1 of the rotor 11 put and underlying be to refer to relative position, the placement position of general reference rotor 11 is higher than rotor 1, vice versa, no matter axes O 2 is to adopt to be arranged vertically or to adopt to be in tilted layout,, put with the implication of underlying just constant on it as long as their relative position meets aforesaid regulation.Certainly, when rotor 11 and the horizontal layout of rotor 1 employing, that is their axis employing horizontal layout or cardinal principle horizontal layout (not shown), this programme is still effective.

Obviously, because bearing 10a and bearing 10b are arranged in the same side of rotor 11, so both distances have furthered widely, and the result extremely helps controlling the coaxality of their axis; Especially, they in addition can be installed on the same parts, so just be more prone to guarantee the coaxality of their axis; Thus, the difficulty of the manufacturing of compressor, installation and debugging just can descend.

It must be noted that at last, the bearing that is used for supporting revolving shaft can adopt two, shown in above-mentioned embodiment, also can adopt several bearings to support, even can adopt a long bearing to support, no matter the number of supporting revolving shaft how,, just belong to category of the present utility model as long as they are arranged in the same side of rotor.
