Abstract: This disclosure relates to bearing support comprising a relatively rigid collar ring for direct support of a bearing. The relatively rigid collar ring is press fit inside a bearing supporting hub of a nonmetal (such as a composite polymer) bearing support. The design of the relatively rigid collar ring and the composite polymer bearing support is such that the stresses in the construction are satisfactory for long-term performance and reliability. The bearing supporting hub includes discrete supporting hub panels and there are axial slots between the hub panels. The supporting hub panels further include radial rib sections extending axially for strengthening the supporting hub panels and for adding support for the relatively rigid collar ring. The inside diameter of the supporting hub panels is tapered to provide stress relief clearance. Contacts between the inside of the supporting hub panels and the collar ring are limited to discrete locations.

Abstract: A damper film bearing assembly for supporting a rotatable shaft of a turbomachine includes a housing having a central bore sized to receive the bearing member, and an annular cavity formed within the housing around the central bore. The annular cavity includes an outer wall that is concentric with the central bore.

The arcuate portions are pressed by a plurality of ribs. Since the leaf spring is pressed by wall surfaces of the holding groove at all times, a frictional force between the leaf spring and the shaft is kept constant and a resisting torque is stabilized.

Abstract: A beating assembly for a submersible motor/propeller unit for a water vehicle consists of a radial bearing assembly and a thrust bearing assembly associated with a propeller and an axle. The radial and thrust bearing assemblies are comprised of bearing components, preferably made of a hard material to provide "hard-on-hard" bearing surfaces, and a resilient backing means, preferably rubber, positioned behind the stationary bearing component. The "hard-on-hard" bearing surfaces increase the load capacity and operating life of the bearings, and the resilient backing means allows the propeller to be displaced under high impact shock loads and to transfer the shock loads to shock snubber locations between the rotor and the stator. The combination of "hard-on-hard" bearings with the resilient backing means provides control of the centering of the propeller on the shaft and longer operating life for the propeller unit, as well as increased capability to survive high shock loads.

Abstract: A belt drive train particularly useful for driving the beater bar of a vacuum cleaner. The drive train includes a driven shaft preferably driven by a motor, a drive shaft preferably connected to a beater bar and including a driven pulley, and an inelastic belt coupling the drive shaft to the driven shaft. Both the drive shaft and the driven shaft are supported on bearings. At least one of the bearing is mounted in a deflecting bearing mount so that the shaft supported by the bearing can be moved relative to the housing. As a result of this construction, the drive shaft and the driven shaft can be moved closer to one another to allow the inelastic belt to be passed over the drive shaft and the driven shaft. The elasticity of the deflecting bearing mount then causes a belt tension sufficient to allow the drive shaft to drive the driven shaft through the belt. The drive train can also include one or more self aligning sleeve bearings to compensate for the unbalanced belt tension force.
