A noise reducing apparatus of a speed reduction device for electric continuous variable valve timing (CVVT), may include the speed reduction device having an inner tooth portion formed to be faced opposing an external wheel of a ball bearing in an interior diameter surface of a housing that may be integrally formed with a sprocket and rollers arranged through a cage between an inner tooth of the inner tooth portion and the external wheel of the ball bearing, wherein a coating layer may be formed to ease impact in exterior circumference portions of the rollers.

A roller of a support arrangement for a rotary milking platform, where the support arrangement includes a first rail member fixedly connected to the rotary platform, a second rail member stationarily arranged in a position below the platform, and a plurality of rollers arranged in a vertical space between the first rail member and the second rail member. Each roller includes a peripheral surface comprising a contact surface to be in contact with a contact portion of the first rail member and a contact portion of the second rail member. The peripheral surface of the roller includes two beveled surfaces arranged at opposite sides of the contact surface which are located at a smaller distance from a rotary axis of the roller than the contact surface.

An axial control assembly comprises a bearing assembly and a bearing mount assembly, wherein the bearing mount assembly is structured to secure the bearing assembly in an operative configuration relative to a rotatable element of a mechanical device. The bearing assembly includes an inner bearing casing and an outer bearing casing structured to rotatably engage one another. The bearing mount assembly includes at least one axial control member disposed in an abutting relation to an axial load surface of one of the inner or outer bearing casings, and the axial control member is further positioned to counteract an axial load generated by a rotational movement of the rotational element of the mechanical device. A lubrication system provides a precisely controlled amount of lubricant to the bearing assembly during operation.

A diagnostic scanning apparatus includes a hollow rotor sized to receive a patient. First and second flanges are connected to and extend radially outward from the rotor in a spaced-apart relationship, each of the first and second flanges including, at least in part, a magnetically-permeable material. A radiation source is affixed to the first flange and/or the rotor. A first axial actuator generates a variable magnetic field, is fixedly disposed adjacent to the first flange and can magnetically pull the first flange in a first axial direction of the rotor. A second axial actuator generates a variable magnetic field, is fixedly disposed adjacent to the second flange and can magnetically pull the second flange in a second axial direction of the rotor that is opposite of the first axial direction. The first and second axial actuators are both at least substantially disposed between the first and second flanges.

A magnetic conveyance system comprising a support structure having a ferromagnetic capacity and a trolley moveable upon the support structure in a plurality of directions. The trolley may include a trolley frame and at least one attractor cell disposed on the trolley frame. The at least one attractor cell may comprise a housing and at least one magnet, at least one friction reducing load spreading device, and a load transfer member disposed within the housing. The magnet may provide a magnetic attraction force between the trolley and the support structure. The friction reducing load spreading device may comprise a plurality of bearing balls circulating within a reservoir and a channel formed by the load transfer member disposed within the housing. The load transfer member may also include a bearing surface wherein a portion of the plurality of bearing balls is disposed between the bearing surface and the support structure.
