Embodiment
The first embodiment
As shown in Figure 3, according to the present invention, the motion of variable compressor comprises position-arresting disk 33, swash plate 32, main shaft 31.Position-arresting disk 33 is fixedly connected on main shaft 31, swash plate 32 slidably is connected with main shaft 31, be provided with the first Returnning spring 38 between position-arresting disk 33 and swash plate 32, swash plate 32 opposite sides are provided with the second Returnning spring 39 and are located by jump ring 40, two action of reset spring are in swash plate 32, be used for to adjust the initial position of swash plate, and be subject to different pressures and be used for cushioning the pivot angle pace of change when changing pivot angle when swash plate.Position-arresting disk 33 towards a side of swash plate 32 with a confined planes 33a, swash plate 32 stretches out a lug 32a towards a side of position-arresting disk accordingly, this lug can slide on this confined planes, confined planes 33a can limit the position of swash plate 32.
With reference to figure 4, Fig. 5, shown in Figure 6, swash plate 32 is with kidney-shaped mesopore 35, and the left and right sides of this kidney-shaped mesopore 35 is plane 35c, and the arc-shaped surface 35d of both sides, up and down for tilting is inclination alpha between the axis of arc-shaped surface 35d and main-shaft axis.Main shaft has kidney-shaped axle 36 in the part that is connected 32 with swash plate, matches with the kidney-shaped mesopore 35 of swash plate 32, and the left and right sides of this kidney-shaped axle is plane 36c, and the both sides, up and down are arc-shaped surface 36d.The other end of swash plate 32 contacts with position-arresting disk 33 when swash plate 32 pivot angles are maximum with a position limit socket 32e, stops and continues to increase pivot angle.
Cooperatively interact between kidney-shaped axle 36 and kidney-shaped mesopore 35, so main shaft drives the swash plate synchronous rotary.When swash plate bears clockwise torque M 1 and when causing pivot angle to increase, inclination alpha reduces gradually, when position limit socket 32e was inconsistent with position-arresting disk 33, swash plate 32 pivot angles can't increase again, and inclination alpha is near 0 at this moment.
Fig. 5 is the cross section that in Fig. 3, main shaft passes the kidney-shaped mesopore place of swash plate, and the most inboard is the cross section of main shaft 31, and in the part of passing through kidney-shaped mesopore 35, main shaft provides kidney-shaped axle 36, and the profile line that is positioned at kidney-shaped axle 36 outsides is the kidney-shaped mesopore 35 of swash plate.
The second embodiment
As shown in Figure 7, position-limited lever 53 replaces position-arresting disk 33, comprises the shaft-like of confined planes 53a, and position-limited lever 53 can be cylindric, and this confined planes 53a is arranged at the side towards swash plate 32.Position-limited lever 53 is inserted in the hole of main shaft 31 (or main shaft sleeve), and is fixing with pin 54 between position-arresting disk and main shaft (or main shaft sleeve).But position-limited lever 53 is fixed in main shaft 31 does not pass main shaft.
Therefore position-limited lever 53 in fact only is positioned at a side of main shaft, therefore, there is no the restriction site (i.e. position limit socket 32e in the first embodiment) of the maximum pendulum angle of swash plate, and when the inclination arc surface of swash plate mesopore 35 and kidney-shaped axle 36 collided, pivot angle increased to the limit.Namely take the limited part of kidney-shaped axle 36 as the swash plate pivot angle.Adopt the second embodiment's structure can further alleviate the weight of motion.
Need to prove, except above-mentioned two kinds of embodiments, the swash plate lug can be set to two (in the first and second embodiments, lug is all one), i.e. similar forms of the prior art; The cross section arc of kidney-shaped mesopore (kidney-shaped axle) also can be made change, as oval arc etc.; Between position-limited lever and main shaft also available key be connected, can reach approaching effect.
Compressor motion of the present invention has alleviated mechanism's weight, has simplified the structure of position-arresting disk and swash plate, improves the stability of operation, reduces manufacture cost.
Above-described embodiment is to provide to being familiar with the person in the art and realizes or use of the present invention; those skilled in the art can be in the situation that do not break away from invention thought of the present invention; above-described embodiment is made various modifications or variation; thereby protection scope of the present invention do not limit by above-described embodiment, and should be the maximum magnitude that meets the inventive features that claims mention.
