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.

Abstract: An apparatus which may be used to drivingly engage a rotating shaft, reduce the effect of the diametral runout thereof and drive a rotary sensor, including a sleeve placed coaxially about the shaft, drivingly engaging the shaft by means of mating splines. Any diametral runout (eccentric or displaced rotation) present in the shaft is directly imparted to the driven end of the sleeve. A spherical annular protrusion extends radially outwardly from the sleeve and slidingly engages a bore having a central axis coincident with the preferred axis of rotation. In this manner, the center of the spherical annular protrusion, and consequently that portion of the sleeve, is maintained coincident with the preferred axis of rotation. The opposing end of the sleeve drivingly engages a rotary sensor with mating splines. If diametral runout is present in the rotating shaft, the sleeve will gimble about the center point of the spherical annular protrusion 30.

The sleeve also defines an external face which closely conforms to the inner surface of the bearing ring such that angular movement of the sleeve within the bearing ring is permitted while axial movement of the sleeve relative to the bearing ring is inhibited.

Abstract: A railway locomotive truck provides improved mountings and/or configurations for traction motor axle support bearings to improve their wear life. These include tilting, or sloping, of the support bearing bores to more closely match the orientations of the bearing journal surfaces on the axles which slope as a result of bending of the axles under the weight of the locomotive. An added feature is forming the bearing bores with a slight conicity to accommodate slight tilting of the traction motor under heavy loads due to taking up of the clearances in the motor support axle bearings. Other features include various ways of mountings or altering the construction of the axle bearings to provide the desired positioning.

Abstract: A tilting pad journal bearing in which the bearing contributes to vibration damping of the supported rotating part without the necessity of substantially preloading the pads against the journal. In a preferred embodiment for a horizontally mounted shaft, the upper, lesser loaded pads are preloaded lightly against the journal by supplying lubricating oil at low pressure to a narrow interstitial space between each such preloaded pad and the bearing casing. In operation, the interstitial space acts as a flow restriction means to prevent a rapid outflow of oil, restricting the pad and shaft from sudden, vibratory movements.
