    摘要： The present invention relates to a linear drive (1) having at least one toothed rack (20) oriented along a longitudinal axis (L) and at least two slides (30) which are movable transversely to the longitudinal axis (L), and a drive shaft (60), wherein the at least two slides (30) are coupled to the drive shaft (60) in such a way that the at least two slides (30) each carry out at least one cyclic and out-of-phase movement in the course of one revolution of the drive shaft (60) and thereby push off by an operative contact at the at least one toothed rack (20) to generate propulsion in a direction of the longitudinal axis (L), wherein the linear drive (1) has at least one compensation means (15), by means of which the operative contact between at least one of the at least two slides (30) and the at least one toothed rack (20) is preloaded

    摘要： An actuator includes an electric motor, a power transmission mechanism having a worm provided in a motor rotating shaft of the electric motor and a worm wheel engaging the worm, a drive member connected to the motor rotating shaft through the power transmission mechanism and displaced according to a rotation of the motor rotating shaft, a control device determining a rotational range of the motor rotating shaft between an initial position and a driven position, and an urging device provided in the motor rotating shaft and urging the motor rotating shaft to the initial position. In case electricity is supplied to the electric motor, the motor rotating shaft rotates to the driven position against an urging force of the urging device, and in case the electricity is not supplied to the electric motor, the motor rotating shaft is urged by the urging device to rotate to the initial position.

    摘要： A rack-and-pinion type steering device includes a ball joint for connecting a rack shaft and a tie rod. The ball joint includes a socket and a ball. The socket is provided with a regulated surface allowed to contact a regulating surface of a rack housing, and a screw projecting from the regulated surface to be connected to the rack shaft. The regulated surface includes an intermediate portion having a curved surface shape that recedes from a regulating surface in a longitudinal direction of the rack shaft toward the outer circumference, and the regulated surface has such a shape that a pointed portion toward the regulating surface is less likely to be formed on the regulated surface even if a processing error occurs in the processing for forming the regulated surface of the socket.

    摘要： A valve, e.g. of an aircraft drinking water system, has a rotatable adjusting shaft to adjust the valve between its open end position and its closed end position. A mechanism for operating the adjusting shaft includes a push-pull cable connected to a toothed rack that engages a toothed gear element secured to the adjusting shaft. The mechanism converts the push-pull linear motion of the cable to a reciprocating rotational motion of the adjusting shaft. End sections of the rack and the gear element have no gear teeth, so the rack automatically disengages from the gear element once the end position of the valve is reached. The disengaged rack can slide beyond the stopped end position of the gear element, and re-engages with the gear element once it slides back into the operating range. The valve cannot be forced beyond its end positions, despite excessive input motion of the cable.

    摘要： A vehicular steering device includes a turning shaft, a housing storing therein the turning shaft, a stopper provided at a shaft end of the turning shaft, and an annular elastic body. An opening of the housing is formed in a U-shaped cross-sectional shape and in an annular shape opened toward the stopper by an external cylinder portion and an internal cylinder portion. The elastic body includes a first elastic portion and a second elastic portion. The first elastic portion is supported by an inner circumferential surface of the external cylinder portion and the bottom surface, and is provided with a first clearance from an outer circumferential surface of the internal cylinder portion. The second elastic portion extends toward the stopper from the first elastic portion, and is provided with a second clearance larger than the first clearance from the inner circumferential surface of the external cylinder portion.

    摘要： The rack housing has an engaging concave section having a bottom surface configured by a bottom inclined surface that is inclined in a direction outward in the radial direction toward the opening side of the rack housing, and the rack bush comprises an engaging convex section having a top surface configured by a top inclined surface that is inclined in a direction outward in the radial direction toward the opening side of the rack housing. The top inclined surface is pressed against the bottom inclined surface toward outside in the radial direction, and the outside surface of the engaging convex section facing the opening side of the rack housing is pressed against the inner side surface of the engaging concave section facing the inner side of the rack housing.
