ABSTRACT:
The improved shaft support means described herein provides a means for resiliently supporting and damping the vibrations occurring in a shaft in a turbo-machine or the like. The bearings supporting the shaft are located in bores formed in the housing of the turbo-machine. The shaft is oriented in an horizontal directiion and the housing is split along a horizontal plane extending through the bore. The upper portion of the bore is provided with a groove that is formed on a centerline coincident with the centerline of the bore. The lower half of the bore is provided with a groove that is formed from a centerline located above the centerline of the bore so that the lower portion of the groove is of less depth than the groove of the upper portion of the bore. An O-ring or the like is disposed in the groove encircling the bearing. As a result, a greater force is exerted by the O-ring in the lower portion of the bore than in the upper portion of the bore so that compensation is made for the weight of the rotor and shaft assembly in the design of the turbo-machine. Thus, compensation is made in the design of the turbo-machine for the weight of the shaft and rotor while at the same time providing resilient damping means to accommodate the vibrations of the shaft and rotor during operation.
