Abstract

The utility model is a rolling rotor compressor which is provided with a radial adjustment and the rolling rotor compressor changes the rolling of the rolling rotor drove by the bent axle directly to the rolling of the rolling rotor drove by the bent axle through the radial adjustment cover. The radial adjustment cover is respectively machined a hollow chamber in the orientation of the maximum and minimum offset of the bent axle, one end is the high-pressure oil chamber, and the other end is the low-pressure oil chamber. The pressure difference of the two chambers and the resultant force of the other various forces can cause the back and forth movement of the radial adjustment cover to compel the contact status between the rolling rotor and the cylinder face gapless or generated without the excess compressional force, and the pressure difference of the two chambers the resultant force can reduce the machine precision and assembly precision of the key components and parts of the rolling rotor compressor and can solve the large difficult problem of the manufacture. The manufacture is much easier, and the production efficiency and production quality are can be improved. The utility model also can start in fractional load and can extend service life.

Description

Rolling rotor type compressor with radial regulation.

Technical field:

The utility model is a kind of rolling rotor type compressor that is applied to air conditioner, especially a kind ofly can eliminate the rolling rotor type compressor with radial regulation that radial clearance can be avoided extruding force again automatically.

Background technique:

Existing rolling rotor type compressor, have many advantages, but what this compressor adopted is to decide crankshaft designs, be that the crank throw of bent axle directly drives rolling rotor and rolls along cylinder inner wall, the contact condition of rolling rotor and cylinder inner wall, i.e. gap length between the two or extruding force size are fully by combined factors such as the assembly precision decision of the concentricity at external diameter precision, cylinder bore diameter and crank throw diameter precision and crank up center and cylinder-bore center in the offset precision of crankshaft crank, the rolling rotor.Therefore, contact condition between the two can only be controlled by the mechanical tolerance of strictness and careful assembling adjustment.If make rolling rotor in cylinder inner wall rolls a week, all can obtain zero clearance and the contact condition that did not have extruding force, this is very difficult, also is impossible, so the production difficulty is big, and can not no-load starting.

Summary of the invention:

Decide the problem of crankshaft designs existence in order to overcome existing rolling rotor type compressor, non-ly decide crankshaft designs but the utility model has adopted radial regulation.It not only has the advantage of existing rolling rotor type compressor, and can be under the condition of machining accuracy that reduces major part and assembly precision, drive rolling rotor by the radial regulation cover on the crankshaft crank and roll, automatically make the contact condition of rolling rotor and cylinder inner wall remain the zero clearance and not have extruding force along cylinder inner wall.It is also easier to produce.

The technological scheme that its technical problem that solves the utility model adopts is: on the basis of existing full-sealed rolling rotator compressor, bent axle is directly driven rolling rotor to rotate along cylinder inner wall, change into by bent axle and rotating along cylinder inner wall by radial regulation cover drive rolling rotor, and radial regulation is enclosed within on the orientation of crank throw offset minimax of bent axle, each processes a cavity, one end is a high-voltage oil cavity, and an end is the low pressure oil pocket.When crank up, by the pump oil of the oil of the pump in bent axle endoporus sheet, will have the oil of high-pressure gas pressure, the high pressure oilhole on the maximum orientation of crank throw offset is pressed into the cavity on this orientation, forms high-voltage oil cavity.And the cavity on the minimum orientation of crank throw offset, release groove and low-pressure admission chamber by certain position on the upper end cap on the cylinder block communicate, and form the low pressure oil pocket.The pressure difference of this two oil pocket is enough to overcome pressurized gas in the cylinder and gives making a concerted effort of the pressure of rolling rotor and thrust that moving slide plate is given rolling rotor.When part's machining errors and assembly error cause rolling rotor and cylinder inner wall gap big, promote rolling rotor by the pressure difference in two chambeies and move, thereby eliminate both gap to cylinder inner wall; When error caused rolling rotor and cylinder inner wall gap to be negative value, it is big that extruding force becomes, and its total pressure then can promote rolling rotor and force the radial regulation cover to move to the gyration center direction again greater than the pressure difference in two chambeies, thereby avoided crossing extruding force.When starting, because of two oil pockets do not have pressure difference, rolling rotor does not have big rigidity again with cylinder inner wall and contacts, thereby starting load is less.

The beneficial effects of the utility model are, have the rolling rotor type compressor of radial regulation, and the machining accuracy of a plurality of vital parts can be relaxed, and assembly precision can loosen, and it is easier to make, and working life is also longer, and the up-to-standard rate and the quality of product of product are higher.This both reduced cost, and enhanced productivity again.Simultaneously, but also light-load starting.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a kind of embodiment with rolling rotor type compressor of radial regulation, is the B-B longitudinal sectional view of Fig. 2.

Fig. 2 is the A-A sectional drawing of Fig. 1.

Among the figure, 1, cylinder block 2, moving slide plate 3, rolling rotor 4, radial regulation cover 5, carry-over moment plane 6, the crank throw 7 of bent axle, high-voltage oil cavity 8, high pressure oilhole 9, low pressure air cavity 10, upper end cap release groove 11, low pressure oil pocket 12, cylinder inner wall 13, crank up center 14, pump oil sheet 15, lubricant oil throttle orifice

Embodiment:

In the drawings, the crank throw (6) of radial regulation cover (4) and bent axle by carry-over moment plane (5), forms rigid rotation.But on crank throw offset minimax orientation, respectively leave high-voltage oil cavity (7) and low pressure oil pocket (11), move for the radial regulation cover.The high pressure of high-voltage oil cavity is by pump oil sheet (14) pump high pressure oil, and the endoporus through bent axle gyration center (13) again through high pressure oilhole (8), enters that high-voltage oil cavity sets up.And the low pressure of low pressure oil pocket is to be communicated by the release groove (10) of the upper end cap of cylinder block (1) and low pressure air cavity (9) to form.Simultaneously, this release groove does not make high-voltage oil cavity and low pressure air cavity be communicated with again.This groove is in by the crank up telegoniometer, and is more suitable in the position that the below of moving slide plate (2) is 90 °-270 °.Because the pressure difference of high-voltage oil cavity and low pressure oil pocket, radial regulation is enclosed within on the crank throw offset minimax orientation of bent axle moves around, thereby realize the contact condition of rolling rotor (3) and cylinder inner wall (12), not only there is not the gap but also do not have extruding force.As for the lubricant oil between radial regulation cover and the rolling rotor, be by the oil in the high-voltage oil cavity, the lubricant oil throttle orifice (15) that puts through radial regulation is supplied with.
