Abstract: A motor arrangement on the steering wheel of a vehicle has a motor, a friction wheel drivable by the motor and engagable against the steering wheel, and a motor mount having a main support that is securely connectable to the vehicle and a motor support that is mounted on the main support for pivotal movement about an axle and is securely connectable to the motor, and a spring bearing against the main support and the motor support and attempting to turn the motor support relative to the main support in a direction of engagement. The motor arrangement includes a locking device which limits the pivoting movement of the motor support relative to the main support, adopts a locked position upon reaching a first pivot angle as the result of a pivoting movement of the motor support in the direction of disengagement, and is unlockable by a pivoting movement in the direction of disengagement which exceeds the first pivot angle by a second pivot angle.

Abstract: A friction drive device transmits torque by frictional contact between rollers. The friction drive device includes a casing, a drive roller that is supported for relative rotation with respect to the casing, a driven roller that is supported for relative rotation with respect to the casing, a cam mechanism that presses the drive roller and the driven roller into contact with each other, and a damper. The cam mechanism includes a surface that is disposed at an angle with respect to a tangent of the contact between the drive roller and the driven roller, and includes a rotational support part that is disposed on the surface and supports one of the drive roller and the driven roller such that displacement along the surface by the rotational support part maintains the frictional contact for transmitting the torque. The damper reducing vibration of the rotational support part.

Abstract: A spindle drive for a movable component includes a threaded spindle, which can be driven in rotation about a rotational axis by a reversible drive. A spindle nut is mounted nonrotatably on the spindle. By means of the spindle nut, a transmission element connected to the movable component can be driven axially with respect to the spindle axis. The spindle nut can be connected to and disconnected from the transmission element by a connecting device. A nut position sensor detects the position of the spindle nut and a component sensor detects the axial position of the transmission element. If it is concluded that there is plausibility between the signals of the nut position sensor and the component sensor, the spindle nut can be connected to the transmission element by the connecting device.

Abstract: An XY coordinate measuring stage includes a drive unit for a coordinate axis. The drive unit has a friction rod and a motor, the motor including a motor shaft in contact with a side of the friction rod. An applied pressure roller contacts an opposite side of the friction rod. At least one applied pressure spring urges the applied pressure roller, the friction rod, and the motor shaft against one another with an applied pressure force so that the motor shaft frictionally engages the friction rod, converting a rotational motion of the motor into a linear motion of the friction rod. A compensation device associated with the motor shaft generates a compensation force onto the motor shaft oppositely to the applied pressure force so as to at least partially compensate for the applied pressure force.

Abstract: The present invention provides a mechanical continuously variable transmission in which the power roller is in “line contact” with the counter roller instead of conventional “pinpoint contact”. By utilizing line contact of the power roller and the counter roller, the pressure force between the metal components of a mechanical continuously variable transmission can be reduced. In addition, the line contact also reduces extra energy for maintaining the operation thereof. The configuration of the roll surface of the power roller, which is rotated by a rotation axle connected to an input axle, is formed into a partial configuration of a sphere. A plurality of counter rollers, which are in line contact with the power roller having said roll surface, are arranged in a circle by a disk. Each counter roller is formed with a concave roll surface corresponding to the partial configuration of the sphere on the surface thereof.

Abstract: A positioning apparatus includes a machine bench 1, an external pressure linear bearing assembly 2 and a slide body 3 mounted on the machine bench 1 through the bearing assembly 2 for reciprocating movement relative to the machine bench. The positioning apparatus has a frictional reciprocating drive mechanism 4 for reciprocatingly driving the slide body 3 which is provided and includes a main shaft 5 adapted to be rotated, and a plurality of rollers 9 disposed around the main shaft 5 and inclined at a predetermined angle relative to the main shaft 5. Each roller 9 is pressed relative to the main shaft 5 by a pressing member 15. The slide 3 and a rail 20 are made of ceramics. Magnets 41 are provided on the slide body 3 for developing forces of magnetic attraction between magnetizable members 42, provided on the machine bench 1, and the slide body 3.

Abstract: An electric propulsion system for a bicycle, comprising a mounting structure adapted for connection to a frame portion of the bicycle, a drive roller, and first and second motors coupled to the mounting structure. Each of the first and second motors includes an output shaft joined to the drive roller and a first resilient bushing around the output shaft. The first resilient bushings of the first and second motors allow for translational movement of the first and second motor output shafts together with the drive roller.

Abstract: There is provided an improved turntable structure wherein a turning plate may be motor-driven or manually driven at the option of a user. The turntable includes a turning plate supported on a base plate via a rotation ring assembly. On the bottom surface of the turning plate is mounted a driving device from which extends a tie rod by which the user may manipulate the position of a driving wheel in the motor of the driving device to engage or disengage from the rotation ring assembly. The rotation ring assembly includes an upper sleeve affixed to the bottom surface of the turning plate, a lower sleeve affixed to the top surface of the base plate, and a bushing circumferentially opposing both the upper and lower sleeves. A plurality of roller balls are captured in aligned grooves formed into opposing surfaces of each of the upper and lower sleeves and the bushing.

Abstract: A reciprocating mechanism is provided with a motor rotating in one direction to produce forward and reverse motion by a drive wheel in direct contact with the forward and rear surfaces of an element such as a plate. The plate can take the form of a sliding door covering a vanity mirror in a vehicular sun visor.

Abstract: A parts washing machine is provided for cleaning and degreasing, e.g., automotive parts which includes a tray rotatably mounted within an enclosure. A drive mechanism is provided for rotating the tray which includes a drive member such as a gear which is mounted on a pivot arm for operative engagement with the tray. By positioning the drive axis of the drive member more proximate to the circumferential wall of the tray than the pivot axis, the drive member remains in engagement with little or no additional force required to maintain a driving relationship between the drive member and the tray.
