Embodiment
The utility model is intended to propose a kind of rotation-preventing mechanism of swing compressor, comprising: be arranged on the axial boss on the planetary plate, axial boss is provided with the pin-and-hole that radially extends; Ball stud with bulb and pin handle, the pin handle of ball stud is inserted in the pin-and-hole slidably; Crawler shoe in axial sliding in chute, the bulb and the crawler shoe of ball stud are hinged.
Crawler shoe has and hinged spherical concave surface of bulb and the cylindrical lateral surface that is slidingly connected with chute.Crawler shoe comprises two symmetric parts, is combined to form the above spherical concave surface of hemisphere, and bulb is contained in this sphere concave surface.
The central angle of the longitudinal section of spherical concave surface is greater than 180 °.The pin handle radius of ball stud be ball stud the bulb radius 50%～85%.Better, the pin handle radius of ball stud be ball stud the bulb radius 55%～70%.
Fig. 2-4 has disclosed the structure according to an embodiment's of the present utility model swing compressor with rotation-preventing mechanism.Wherein Fig. 3 has disclosed the amplification assumption diagram that bulb cooperates with crawler shoe, and Fig. 4 has disclosed ball stud and crawler shoe situation in axial sliding in chute.
As shown in Figure 2, in the cylinder body 1 of swing compressor, main shaft 3 and swash plate 5 are around axial rotation, the end face of swash plate 5 promotes planetary plate 7 and does axial oscillating motion, reciprocating in cylinder-bore 11 separately with the hinged a plurality of pistons 9 of planetary plate 7 respectively, realize compression to cylinder-bore inner refrigerant gas.The rotation-preventing mechanism of planetary plate 7 is set, has axial boss 13 on the planetary plate 7, axial boss 13 is provided with the pin-and-hole 14 that radially extends, crawler shoe 15 can endwisely slip in chute 12, hinged between ball stud 17 and the crawler shoe 15, ball stud has bulb 17a and pin handle 17b, and pin handle 17b is inserted in the pin-and-hole 14 slidably, and bulb 17a and crawler shoe 15 are hinged.
With reference to (Fig. 3 is the A-A sectional view among Fig. 2) shown in Figure 3, the cylindrical lateral surface 15d that crawler shoe 15 has the spherical concave surface 15c hinged with bulb 17a, is slidingly connected with chute 12.Crawler shoe 15 comprises the part of two symmetries, is combined to form more complete spherical concave surface, and this sphere concave surface can cover the above area of hemisphere greater than hemisphere, and bulb 17a is contained in this hemispheric spherical concave surface.Because the bulb 17b of ball stud 17 is limited in the chute 12 by crawler shoe 15, can't rotate around the compressor axis, and the circumferential displacement between ball stud 17 and the planetary plate 7 is limited, and planetary plate 7 can't be spinned.But because ball stud 17 can axially slide in chute 12 with crawler shoe 15, and can and crawler shoe 12 between relatively rotate, so the axial oscillating motion of planetary plate 7 is not limited.
As shown in Figure 4, the situation when position P1 and position P2 represent respectively that the ball stud 17 of planetary plate is expert to two summits up and down promptly arrives at two end points of chute 12.Because ball stud 17 can slide in the pin-and-hole 14 of planetary plate 7, in order to prevent that ball stud 17 from coming off from crawler shoe 15, the arc length of the spherical concave surface of the crawler shoe 15 shown in Fig. 4 section should be a bit larger tham the bulb 17a of ball stud 17, and promptly the central angle alpha of the longitudinal section of spherical concave surface should be greater than 180 °.In P1 and P2 position, pin handle 17b can not interfere with spherical concave surface and crawler shoe 15 other positions of crawler shoe 15, in case interference can cause compressor to kill, therefore needs the dimension scale of restriction pin handle 17b and pin head 17a.On the other hand, pin handle 17b meticulous meeting causing strength deficiency and bending.Therefore, the pin handle radius of ball stud be ball stud the bulb radius 50%～85%, better, the pin handle radius of ball stud be ball stud the bulb radius 55%～70%.Below table 1 in the size combinations mode provided the design parameter of central angle of the longitudinal section of the pin handle radius of ball stud and bulb radius and crawler shoe:
Table 1
| The central angle alpha of crawler shoe longitudinal section | Pin handle radius R 1 (cm) | Bulb radius of a ball R2 (cm) |
| 195° | 3.6 | 5.5 |
| 220° | 3.4 | 5.5 |
The rotation-preventing mechanism of the swing compressor that the utility model proposes has advantage simple in structure, that volume is little, and has good sliding capability, and is not easy to wear.
The foregoing description provides to being familiar with the person in the art and realizes or use of the present utility model; those skilled in the art can be under the situation that does not break away from model utility thought of the present utility model; the foregoing description is made various modifications or variation; thereby protection domain of the present utility model do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
