Abstract:
A driving device for driving in rotation a toothed wheel, in particular a turntable, has a worm intended to mesh with the toothed wheel, a motor to drive the worm in rotation, a flexible sleeve that partially surrounds the worm in such a way as to form an assembly described as a worm/sleeve assembly, and a pre-stressing unit. The motor is arranged in a structure that is fitted pivotably relative to the worm/sleeve assembly, and the driving device also has a force transfer unit connecting the motor to the sleeve at a second extremity of the worm.
Abstract:
A gear box includes a gear box body of a reducer to which a motor is mounted. The gear box body includes a worm, wheel holding section where a worm wheel of the reducer is held, and a motor holding section, where a part of the motor is contained, the motor holding section having a motor mounting opening. The motor holding section is configured such that a bottom of the motor holding section is provided in a region between a line L1 and a line L2. Here, the line L1 passes through the center C of the worm wheel holding section and is perpendicular to the axis line X of a motor shaft. The line L2 is a tangent line passing through an outer edge portion located near a circular outer peripheral wall of the worm wheel holding section on a motor side and is perpendicular to the axis line X of the motor shaft.
Abstract:
The present invention relates to an adjustment drive, in particular for a vehicle, for driving a component, comprising a drive unit having comprises a first output shaft, wherein an output unit or an intermediate unit, which is disposed between the input unit and the output unit, can be adapted in a modular manner to the first output shaft.
Abstract:
A worm reduction gear that reduces a rotation of a worm and transmits the reduced rotation to a worm wheel includes a casing that houses the worm and the worm wheel, wherein the casing includes: a wheel opposing surface that opposes an end surface of the worm wheel via an interval; and a grease holding recessed portion formed in a recessed shape in the wheel opposing surface, and the grease holding recessed portion is provided in a position opposing a worm meshing portion between the worm and the worm wheel.
Abstract:
A helical gear mechanism for a steering system in a motor vehicle comprises a helical pinion which engages with a helical gear and a bearing bushing which accommodates a bearing of the helical pinion. An inner ring of the bearing bushing is connected to an outer ring via a pivot bearing so that a pivoting motion of the helical pinion relative to the helical gear is possible. A pressure piece is disposed between the inner ring and the outer ring of the bearing bushing. The pressure piece is movable in a spring-loaded manner in a section of an annular gap between the inner ring and the outer ring. The inner ring and/or the outer ring are designed in the section so that the annular gap between the inner ring and the outer ring is tapered in the direction in which the pressure piece can be moved in a spring-loaded manner.
Abstract:
The invention relates to a superposition drive for a superimposed steering system of a motor vehicle, with a drive shaft and a drive gear cooperating with the drive shaft, wherein the drive shaft is pivotally mounted with respect to the drive gear. A lever element pivotally mounted with respect to the drive gear, which is designed and arranged such that pivoting of the lever element entails pivoting of the drive shaft or vice versa pivoting of the drive shaft entails pivoting of the lever element, is provided.
Abstract:
A gear structure is configured to support vertical motion of an electric pop-up monitor. More specifically, a double rack gear structure is configured to support a pop-up monitor. The rack gear structure includes an outer gear and an inner gear. The outer gear is coupled at a side of the monitor frame to operate integrally with the monitor frame, and enables the vertical motion of the monitor frame with an ascending or descending motion. The inner gear is received inside the outer gear. The inner gear performs an ascending or descending motion simultaneously with the outer gear, and supports forward and rearward or right and left shaking, which occurs in the outer gear, by maximizing a portion overlapping with the outer gear when the outer gear has ascended to the maximum.
Abstract:
The wear-compensation device for a gear comprises a fixed support capable of being fixed axially on an external element in order to keep the device on the said external element, a bearing designed to be mounted on a shaft comprising one of the wheels of the gear, an eccentric mounted on the bearing and designed to be in contact with the external element, the said eccentric being able to move angularly relative to the fixed support. The device also comprises a torsion spring mounted axially between the fixed support and the eccentric and capable of exerting a circumferential preload force on the said eccentric, the said spring comprising a first end mounted inside a recess of the eccentric and a second end interacting with the fixed support.
Abstract:
A linear actuator includes a motor, a movable unit, and a stroke control unit. The motor includes a spindle. The movable unit includes a worm gear and a rotary shaft. The worm is provided with annular spiral or helix teeth. The stroke control unit includes at least one transmission member and at least one micro switch. The at least one transmission member is engaged with and driven by the spiral or the helix teeth of the movable unit for synchronical rotation to activating or deactivating the micro switch. In this way, the linear actuator is simplified in structure and reduced in volume.
Abstract:
This safety system includes: a toothed wheel, connected rotationally with respect to at least one rotating member to be braked, a worm driven rotationally by a motor upon rotation of the rotating member and permanently in mesh with the toothed wheel, a housing forming: a longitudinal wall located on the side of the worm diametrically opposed to the toothed wheel, and extending along the worm at a distance of the latter ranging between 0.001 and 0.01 times the diameter of the worm, and a first end wall integral with the longitudinal wall, located opposite a first longitudinal end of the worm; and energy absorption/dissipation elements interposed between the first end wall and the first longitudinal end of the worm, the worm being slidingly mounted in the housing such that the first longitudinal end of the worm comes closer to the first end wall when the worm slides in the housing.
