摘要:
The present invention relates to an electric motor and an electric power steering apparatus including the same. According to an embodiment of the present invention, problems such as a malfunction of an electric motor, damage to a component of the electric motor, and lowering of an output of the electric motor can be solved by preventing penetration of foreign substances into the electric motor, so that a steering stability of a vehicle can be improved.

An elevator system includes an elevator car located in a hoistway. One or more belts are operably connected to the elevator car to drive and/or support the elevator car along the hoistway. The one or more belts are routed over one or more sheaves. The one or more sheaves include an outer surface rotatable about a central axis and a flange located at at least one lateral end of the sheave. The sheave further includes a tracking compensator to limit lateral motion of the belt along the outer surface to prevent the belt from contacting the flange.

A combustion engine having at least one combustion chamber and a crankshaft is combined with a planetary gear train having a ring gear, a sun gear, and a plurality of planetary gears rotatably mounted on a planet carrier and interacting with the ring gear and the sun gear. In order to dampen or absorb vibrations of the crankshaft of the combustion engine, a vibration damper unit is provided to keep the vibrations away from the planetary gear train. The vibration damper unit includes a support member which is attached to the crankshaft at a location which is in closer proximity of the combustion chambers of the combustion engine than a connection member by which the crankshaft is coupled to the planetary gear train.

In a belt transmission system A, a drive pulley 1 and at least one driven pulley 2-4 are flat pulleys, and power transmission between the pulleys is performed through a substantially flat transmission surface b1 of the power transmission belt B. This can improve transmission efficiency and durability of the power transmission belt to be comparable to those of a flat belt, while significantly reducing the cost of the system. A plurality of protrusions 82a extending in the longitudinal direction of the belt are provided on an outer surface of the belt, and are allowed to engage with circumferential grooves 5a of a restriction pulley 5, 6, thereby restricting movement of the power transmission belt in the lateral direction of the belt. This can keep the belt running stably even when rainwater etc. is adhered to the belt or the pulley.

A wheel, such as a pulley or a sprocket, includes a hub and a sleeve. The hub has an outer surface with a plurality of substantially axially aligned teeth. The sleeve has: (a) an inner surface with a plurality of substantially axially aligned grooves that engage the teeth of the hub; and, (b) an outer band engagement surface that engages a band, such as a belt or a chain. As the band tends to become misaligned with respect to the wheel, the sleeve automatically moves axially with respect to the hub to correct the misalignment.

A pulley body 5 is provided at its both sides with power transmission members 6, 6. When a flat belt 3 becomes misaligned relative to the center of the pulley body 5 and comes into contact with one of the power transmission members 6, a running force of the flat belt 3 is utilized to displace the pulley body 5 diagonally relative to the flat belt 3, thus producing a force for returning the flat belt 3 to its original state.

For endless belting of thin film material having characteristic fabricational twists causing sidewise creeping and wrinkling of such material relative to a pair of pulleys crowned toward center and each having a surface configuration for 180* wrap around engagement to afford alternately opposite inwardly and outwardly tending crosswise forces to such belting and the tensioning of the latter at one edge by an unparallel adjustment between the pulleys to compensate for the creep creating twist in such belting and for smoothing the latter widthwise transversely of the direction of movement thereof over the pulleys.

A filtering pulley has a hub configured to be fixed to a shaft for rotation thereabout, a crown mounted coaxial and rotationally free on the hub, and a plurality of elastic groups arranged circumferentially with respect to the hub and to the crown and interposed, each, between a pair of first elements integral with the hub and between a pair of second elements integral with the crown. The first elements have at least two spokes, carried by an actuator that is made of two portions that are selectively geared between them to selectively connect the crown to the hub.

At least one of a plurality of rollers supporting an endless belt includes a flange arranged on an end portion of the roller. The flange includes a cylindrical portion that is inserted into an opening portion of the roller at its end. Outer circumference of the cylindrical portion makes contact with inner circumference of the roller, and inner circumference of the flange makes contact with a rotation shaft of the roller. The inner edge of a surface where the flange is in contact with the rotation shaft is located on the inner side of the outer edge of a surface where the cylindrical portion is in contact with the roller in the longitudinal direction of the rotation shaft.
