Abstract
An axial complaint mounting system for a scroll machine positions the centroid reaction of the mounting system toward the top of a mounting bore extending through the axial compliant scroll member. The mounting system defines a first clearance located near the top of the mounting bore and a second clearance located near the bottom of the mounting bore. The positioning of the centroid reaction for the mounting system is accomplished by designing the second clearance larger than the first clearance.
Claims33
A scroll machine comprising:
- a first scroll member having a first spiral wrap extending from a first end plate;
- a second scroll member having a second spiral wrap extending from a second end plate;
- a housing for supporting said second scroll member for orbital movement with respect to said first scroll member, said second scroll member being positioned with respect to said first scroll member such that said first and second spiral wraps intermesh with one another so that orbiting of said second scroll member with respect to said first scroll member will cause said wraps to define moving fluid chambers.
- a flange extending from said first scroll member, said flange defining a mounting bore extending through said flange between a first side of said flange and a second side of said flange;
- and
- an axially compliant mounting structure extending through said bore to secure said first scroll member to said housing, said axial compliant mounting structure defining a first clearance adjacent said first side of said flange and a second clearance adjacent said second side of said flange, said second clearance being greater than said first clearance, said axial compliant mounting structure including a bolt extending entirely through said mounting bore and threadingly received by said housing.
