Abstract: A compressor is provided and may include a shell, a hub, an insert, and at least one collar. The hub may be disposed within the shell and define an axis of rotation. The hub may include an axially extending aperture. The insert may be disposed within the aperture. The at least one collar may be disposed about the hub.

Abstract: A scroll compressor includes a compression mechanism contained within a shell. A non-orbiting scroll is supported for axial displacement relative the shell, and includes an end plate having a wrap extending therefrom and a flange having a bore extending therethrough. A guide member is axially fixed relative the shell and extends through the bore in the flange. A first portion of the guide member is disposed within and generally abuts a first circumferential portion of the bore. A second portion of the guide member is disposed within and generally spaced apart from a second circumferential portion of the bore.

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.

Abstract: A foot plate for mounting a compressor includes a mounting plate, a pair of upwardly extending flanges, a pair of downwardly extending flanges and an upwardly extending mounting flange. The mounting flange is utilized to secure a compressor by being attached to the shell of the compressor. When tandem compressor assemblies are used, the pair of upwardly extending flanges provide clearance for a pair of rails which interconnect the tandem compressors without having to modify the foot plates. In one embodiment, the foot plates are welded or brazed to the rails. In another embodiment, a set of grommets position the foot plate on the rail and the foot plate is bolted to the rail. In another embodiment, a set of grommets position and secure the foot plate to the rail.

Abstract: A scroll compressor has a pair of interleaved scrolls. An Oldham coupling is attached to the orbiting scroll to prevent rotation of the orbiting scroll. This Oldham coupling has keys that are slidingly received in slots. One side of each key is loaded while the opposite side is non-loaded. The non-loaded side of the key has a stepped or profiled surface to provide clearance to allow deflection of the key. In another embodiment, the stepped or profiled surface is provided on the non-loaded side of the slot.

Abstract: A scroll compressor has a shell within which is positioned a frame. The frame is supported by a base portion of the shell to prevent axial movement of the frame with respect to the shell. A motor stator, a main bearing housing and a lower bearing housing are each positioned within the shell by engagement with the frame. A drive member which includes a motor rotor is rotatably supported by both the main bearing housing and the lower bearing housing. The frame, by positioning the motor stator, the main bearing housing and the lower bearing housing, allows the “air gap” between the motor stator and the motor rotor to be accurately controlled.

Abstract: An Oldham coupling for a scroll machine has two posts rather than the traditional four posts. Each post of the Oldham coupling of the present invention defines two keys. One key is for engagement with the orbiting scroll. The other key is for engagement with the non-orbiting scroll in one embodiment or for engagement with the main bearing housing in another embodiment. The two posts of the Oldham coupling can be connected by a continuous ring or the two posts of the Oldham coupling can be connected by a connecting member extending between the two posts.

Abstract: A scroll compressor has an orbiting scroll which has an end plate with a hub extending generally perpendicular from the end plate. The hub defines a bore within which a bearing is press fit. The machining of the bore in the hub is done in a conical manner to accommodate and compensate for the unequal distortion of the hub between the two ends of the hub. The conical shape and the unequal distortion provide an assembled bearing with a more cylindrically shaped inner surface.
