The above take scroll compressor as the example brief description structure of rotary compressor.Except the assembly structure of cross slip-ring and main bearing seat, one or more embodiments' of the present invention rotary compressor and rotary compressor of the prior art are roughly the same, are not described in detail in this.
For the purpose of this specification more clearly is described, describe below with reference to Fig. 2.Fig. 2 is the stereogram of the assembly structure of diagram a kind of moving scroll element 64, cross slip-ring 11 and main bearing seat 16.
As shown in Figure 2, main bearing seat 16 has thrust surface 1.This thrust surface 1 is annular.Moving scroll element 64 is seated on the thrust surface 1.Cross slip-ring 11 is supported by main bearing seat 16, and with decide the scroll element (not shown) and moving scroll element 64 matches.When the driving mechanism of compressor was worked, cross slip-ring 11 can move reciprocatingly along the direction of arrow shown in Figure 2.
Fig. 3 is the schematic representation of the force analysis of the moving scroll element 64 of diagram.As shown in Figure 3, moving scroll element 64 is subject to the downward axial load F1 of direction, the thrust load F2 that made progress to its direction that applies by the thrust surface 1 of main bearing seat 16, decides the comprehensive function of scroll element (not shown) to the directed force F3 of its substantially horizontal that applies and driving mechanism (not shown) to the driving force F4 of its substantially horizontal that applies.Wherein, driving force F4 can generate the heeling moment shown in the hollow arrow among Fig. 3, and this heeling moment is so that moving scroll element 64 has the trend of inclination.
Owing to there is thrust surface 1, this thrust surface 1 applies the thrust load F2 that direction makes progress to moving scroll element 64, so the slope trend of moving scroll element 64 is suppressed, can stably move thereby move scroll element 64.
In the ordinary course of things, the area of thrust surface 1 is larger, more can form effectively moving scroll element 64 and support.This is because large thrust surfaces can reduce lip-deep pressure, means large thrust radius R t, thereby can guarantee better the stable operation of moving scroll element 64.
Yet the area of thrust surface can be subject to the restriction of the size of cross slip-ring usually, as shown in Figure 4.Fig. 4 is the schematic representation of the assembly structure of a kind of cross slip-ring 11 of diagram and main bearing seat 16.When cross slip-ring 11 is placed on the main bearing seat 16, between the outer perimeter of the thrust surface 1 of the interior circumference of the ring portion of cross slip-ring 11 and main bearing seat 16, usually can there be gap 3, so that the assembling of cross slip-ring 11.In other words, thrust surface 1 can entirely be enclosed within the ring portion of cross slip-ring 11.So, the occupied zone of the outer perimeter of thrust surface 1 in no case can exceed the zone that the interior circumference of cross slip-ring 11 limits.In fact, consider the existence in gap 3, the zone that the occupied zone of the outer perimeter of thrust surface 1 can limit less than the interior circumference of cross slip-ring 11 usually.In other words, the axis projection of cross slip-ring 11 can surround the axis projection of the thrust surface 1 of main bearing seat 16, and does not have any coincidence.
In an embodiment according to the present invention, in order to enlarge the area of thrust surface 1, can the thrust radius R t of thrust surface 1 be expanded, so that the axis projection of cross slip-ring 11 can partially overlap with the axis projection of the thrust surface 1 of main bearing seat 16.
Because the effect of thrust surface 1 is moving scroll element 64 is formed support, so the area of thrust surface 1 is not subject to the restriction of the size of cross slip-ring 11 inevitably.In the situation of the function that does not affect cross slip-ring 11, surround the axis projection of the thrust surface 1 of main bearing seat 16 compares with the axis projection of cross slip-ring 11, when the axis projection of the thrust surface 1 of the axis projection of cross slip-ring 11 and main bearing seat 16 partially overlaps, the area of thrust surface 1 is increased, thereby so that moving scroll element 64 can more stably move.

Preferably, because the axis projection of the thrust surface 1 ' of the axis projection of cross slip-ring 11 and main bearing seat 16 partially overlaps, so the zone that the occupied zone of the outer perimeter of thrust surface 1 ' can limit greater than the interior circumference of cross slip-ring 11.
When the axis projection of cross slip-ring surrounded the axis projection of thrust surface of main bearing seat, cross slip-ring can be placed on the main bearing seat easily, shown in Fig. 2 and 4.Yet when the axis projection of the thrust surface of the axis projection of cross slip-ring and main bearing seat partially overlapped, cross slip-ring is assembled on the main bearing seat just might become problem.
In a preferred embodiment of the invention, cross slip-ring 11 can be assembled to the groove 4, as shown in Figure 7 from thrust surface 1 ' one side.Fig. 7 is that diagram is according to the schematic representation of the assembly process of the cross slip-ring 11 of the embodiment of the invention and main bearing seat 16.Consider the size of the ring portion of cross slip-ring 11, can design shape and the position of groove 4, be assembled to the groove 4 from thrust surface 1 ' one side to allow cross slip-ring 11.In assembly process, the ring portion of cross slip-ring 11 is tilted, be placed in the groove 4 with the curved portion with the side of the interior ring of cross slip-ring 11.Then, the bottom that is placed on curved portion in the groove 4 and groove 4 of side of the interior ring of cross slip-ring 11 is adjacent to and coincide, be embedded in the groove 4 so that make another part of the interior ring of cross slip-ring 11 cross the outer perimeter of thrust surface 1 '.After the interior ring of cross slip-ring 11 all is embedded in the groove 4, can make the ring portion maintenance level (as illustrated in Figures 5 and 6) of cross slip-ring 11, so that cross slip-ring 11 normally plays a role.
Equally also cross slip-ring 11 can be disassembled from main bearing seat 16 easily.At first, the bottom of the curved portion of side of interior ring of cross slip-ring 11 and groove 4 is adjacent to and coincide, so that the outer perimeter that makes another part of the interior ring of cross slip-ring 11 can from groove 4, withdraw from and upwards cross thrust surface 1 '.Then namely tiltably cross slip-ring 11 is taken out from groove 4.In other words, in technological scheme of the present invention, the Assembly And Disassembly of cross slip-ring 11 and main bearing seat 16 all is very easily.
In sum, the thrust surface on the main bearing seat can form moving scroll element and support, and can guarantee moving scroll element stable operation.The axis projection of the axis projection of cross slip-ring of the present invention and the thrust surface of main bearing seat partially overlaps.Therefore moving scroll element, can obtain larger thrust surface, so that can more stably move.
