Abstract:
1. A method of assembling a refrigerating compressor comprising a sealed chamber laterally delimited by a shell ring, a drive shaft housed in the shell ring and guided with respect to the other components of the compressor by at least one bearing created in a bearing support attached to the to an interior wall of the shell ring, which method comprises the following steps consisting in: supplying the shell ring which, in the plane of attachment of the bearing support, has a cross section of oval overall shape comprising a minor axis along which the bearing support is intended to be mounted, and a major axis, a length of the minor axis being less than a length of the bearing support measured along its longest dimension, applying pressure to the shell ring in order to deform it elastically in such a way as to increase the length of its minor axis, inserting the bearing support into the shell ring, positioning the bearing support in the plane of attachment thereof, along the minor axis of the shell ring, ceasing to apply pressure to the shell ring so that the latter has a tendency elastically to revert to its original shape and grips the bearing support, zones of contact between the bearing support and the shell ring lying more or less on an arc of a circle of a diameter greater than the minor axis, the bearing support maintaining elastic deformation of the shell ring so that the latter exhibits a substantially circular cross section in the plane of attachment of the bearing support.
