Abstract: A universal flywheel locking device which is configured to fit flywheels with a variety of sizes and tooth patterns. The device may feature an arched locking member and two guide members attached to the sides of the locking member. The locking member is configured to wedge the device between a fixed feature or bolt and a flywheel so as to prevent rotation of the flywheel. The first end of the locking member may be configured to fit within a gap between two of a plurality of teeth of the flywheel so as to lock the flywheel.

Abstract: A double clutch transmission of a motor vehicle with a first input shaft (W1) formed as a hollow shaft and a longer, second input shaft (W2) arranged coaxially inside the first input shaft (W1). Each of input shaft is in driving connection, by way of an associated input constant (EK1, EK2), with at least one countershaft (W3a, W3b) arranged axis-parallel to the first and the second input shafts (W1, W2). To avoid jamming of the gearteeth (4, 5a, 5b; 6, 7a, 7b) of the respective, non-load-transmitting input constant (EK1, EK2), the fixed wheel (6), arranged on the associated input shaft (W2) in at least one of the input constants, is arranged in a rotationally fixed manner by first carrier gearteeth (19) on a support sleeve (20) which, in turn, is connected in a rotationally fixed manner by second carrier gearteeth (21, 21?) to the input shaft (W2) concerned.

Abstract: A fixing device and an image forming apparatus using this, in which even if permanent warping is produced on a roller member that forms a fixing nip portion, no collision sound is produced due to the collision of gears, the fixing device including: two roller members that form a nip portion in which a recording medium is pressed by pressure means and transported; and a drive gear that engages with a shaft portion of one of the two roller members and transmits driving force to that roller member. A key is formed in the drive gear and a key groove having a gap opened therein is formed in the shaft portion, and when a rotation velocity of the roller member increases, transmission of driving force from the drive gear to the shaft portion is suspended and the drive gear slides on the shaft portion.

Abstract: In an image printing device, such as a laser printer or ink jet printer, a coupling device for creating a coupling between a rotatable shaft and an interface component, such as a gear. The coupling device is an elongated modified c-shaped body having a portion for receiving the rotatable shaft, and includes integrated hinges that facilitate the coupling device to be spread apart and to receive and interface with the rotatable shaft. The integrated hinges function to compress between the rotatable shaft and interface component substantially inhibiting relative longitudinal movement and wherein a flat on the exterior of the rotatable shaft engages with a flat on the interior the interface component, to additionally inhibit relative rotational movement between the interface component and the shaft. The shaft further includes a plurality of ribs that extend from the rotatable shaft into the coupling device providing additional reduction in rotational movement between the shaft and the interface component.

Abstract: A gear including a gear shaft, and a gear wheel made of a resin material, the gear wheel being fixed to the gear shaft by molding. The gear having a plurality of concave portions and convex portions that repeat in a circumferential direction. The plurality of concave and convex portions are arranged such that they extend in the axial direction of the gear shaft, and arranged such that the convex portions of one concave and convex group are adjacent to the concave portions of the other concave and convex group. Due to the relative displacement of the concave portions and the convex portions, stepped portions are formed at a boundary between the concave and convex groups in the circumferential direction of the gear shaft.

Abstract: A transmission, in particular a dual clutch transmission, has a plurality of transmission shafts and a fastening apparatus for at least one fixed gear on one of the transmission shafts. The fixed gear is held axially on the transmission shaft by way of a fastening nut. The fixed gear is formed with a recess around the transmission shaft in a region that lies radially below the gear toothing system. A fastening sleeve is positioned in the recess between the fixed gear and the transmission shaft in a section which adjoins a fastening nut. During the clamping of the fastening nut, the latter bears against the fastening sleeve. As a result, the transmission of micromovements to the fastening nut is minimized or prevented, with the result that loosening of the fastening nut does not take place during the operation of the transmission.

Abstract: The present disclosure relates to an arrester device for closing apparatus, such as doors, comprising a worm gear rotationally fixedly connected to an output shaft serving as a winding shaft and a self-locking worm which is in communication with an input shaft. In accordance with the present disclosure, an auxiliary worm gear is seated on an eccentric region of the output shaft with clearance, with the auxiliary worm gear having an eccentricity of the same amount as the output shaft and being assembled such that the eccentricities are cancelled with respect to the axis of the output shaft, with the auxiliary worm gear being able to follow the movement of the worm gear without load via its toothed region.

Abstract: A discontinuous linear drive comprises a guiding component and an engaging means. The engaging means engages in a member to be driven and guided by guiding components in at least two places by means of a respective movable engaging component. The member to be driven is driven by a phase-shifted effecting and releasing of the engagement of the moved engaging components.

Abstract: A seat belt retractor having a structure preventing a gear or pinion having external teeth from being improperly assembled to a spool gear. The pinion includes concave portions on its inner periphery and the spool gear includes corresponding convex portions on its outer periphery. The concave and convex portions are configured to be fit together may be inclined in the circumferential direction and thus have no symmetrical plane. If during assembly the pinion is positioned adjacent the spool gear with the wrong side out, the pinion and the spool gear would not fit together and the mistake would be noticed and, therefore, prevented.

Abstract: A thermoplastic power transmission element having increased torque capacity. A power transmission element, such as a gear, pulley, sheave or sprocket, is formed of a thermoplastic material and includes a central hub arranged to surround and engage a keyed driven shaft. A metallic insert within the central hub engages the key to receive the driving forces transmitted therethrough. The metallic insert includes a plurality of mating surfaces engaging the central hub to distribute the driving forces over an area larger than the area of the keyway. Use of the metallic insert increases the torque capacity of the resulting power transmission element.

Abstract: The invention relates to a device for performing rotational movement and comprises a rotatably element such as a cog-sector (3) or the like, arranged in a housing (1). The sector can easily be connected to rotatable machine elements of various kinds by being provided with an easily exchangeable coupling element (7) which can be displaced axially through a bore in the sector and through two bearings (8, 9) and be detachably fastened to the cog-sector by e.g. screws (14, 15) provided in threaded bores in the sector and abutting radially directed support surfaces in recesses in the element (7) between the bearing surfaces of the bearings (8, 9).

Abstract: Seed metering and particle dispensing wheels and to a mechanism for mounting such wheels or other rotative elements to a shaft are disclosed. The wheel has a C-shaped major part with a central opening for receiving the shaft, the free edges of the major part defining a slot extending from the opening to the wheel periphery. A minor part is receivable in the slot to complete the wheel. The minor part at its inner end, and the shaft, are provided with cooperating surfaces which, when engaged, provide a drive connection between the shaft and the wheel. To remove a wheel from the shaft the minor part is withdrawn from the slot and the major part moved transversely of the shaft so that the shaft passes through the empty slot. Replacement or additional wheels can be assembled to the shaft using the reverse procedure.
