Abstract:
A hub assembly for a marine vessel propulsion unit is provided. The hub assembly includes a hub having a splined inner circumferential surface including first axially aligned splines and a further inner circumferential surface radially offset from the splined inner circumferential surface. The hub assembly also includes a seal held by the further inner circumferential surface. The seal includes a splined inner circumferential seal surface having second axially aligned splines aligned with the first axially aligned splines.
Abstract:
A coupling arrangement for connecting a driving member to a driven member to transfer driving torque to the latter employs opposing wedge elements to lock the members together. The wedge elements function to provide large static clearances between the coupling arrangement and driven member upon their engagement and disengagement, enabling the driven member to be readily changed. At the same time, the wedge elements function to automatically take up the static clearance upon insertion of the driven member into the coupling arrangement, and, in addition, automatically compensate for dynamic clearances occurring during operation of the driven member.
Abstract:
A steering arrangement includes a steering spindle having a steering spindle connection connected to a fork crown of a steering coupling via an intermediate piece. The steering spindle connection and the intermediate piece, which is designed as a hub, are formed as plug partners at ends facing each other, by means of at least one tongue and groove guide element pair positioned in the axial longitudinal direction, which provides a torque-transmitting priority control. Torque-transmitting priority control is achieved by a first guide element arranged on the steering spindle connection, a second guide element of the guide element pair arranged on the intermediate piece, and a clamping device that clamps the plug partners together in a plugging position.
Abstract:
A device for fixing the hub of an arm of a wind-screen wiper (2) on a pivoting axis (1) with locking elements (6, 7) for the arm on the pivoting axis (1), a cavity (32) which is created in the hub (2) and is provided with adjusting and angular positioning elements for the arm in relation to the axis (1), whereby the hub (2) rests on the base of a stop (3) which nestles on a radius of operation (4) of the said axis (1); the locking elements (6, 7) are adapted in such a way that they can be engaged in a locking or unlocking position, the adjusting elements includes a connecting ring (10) which is rotationally fixed to the axis (1) and accommodated in the cavity (32) of the hub (2) with a certain amount of play allowing for limited relative angular displacement between the connecting ring (10) and the hub (2) when the locking elements (6, 7) are in an unlocked position, whereby all relative displacement is prohibited between the connecting ring (10) and the hub (2) when the locking elements (6, 7) are in a locked position.
Abstract:
A device for tight fixing a rotary body such as a gear and a pulley, to a rotary shaft such as a motor shaft and a transmitting shaft, provides a slippage between the rotary body and the rotary shaft when an over-load occurs to the rotary body. A groove portion is formed either at the inner surface of a mounting hole in the center of the rotary body or at the outer surface of the rotary shaft, in which a pair of key members having a tapered contact surface are arranged in the longitudinal direction of the rotary shaft. A clamping bolt going through one of key members is screwed into the other key member, and pressed to both key members. Due to the pressure from the clamping bolt, each key member is displaced outward as guided by the tapered surface. One of key members makes a contact with the inner surface of the mounting hole or rotary body, and at the same time, the other begins to press the outer surface of the rotary shaft, respectively. Further force to the key members from the clamping bolt creates a tight fixing of the rotary body and the rotary shaft through the key members. The appropriate fixing force adjusted by the key members permits the slippage between the rotary body and the rotary shaft when the over-load is given unexpectedly.

A steering spindle has a steering spindle connection connected to a fork crown of a steering coupling via an intermediate piece. The steering spindle connection and the intermediate piece are formed as plug partners at ends facing each other, by means of at least one tongue and groove guide element pair, which provides a torque-transmitting priority control. A groove and a tongue of the at least one tongue and groove guide element pair are positioned in the longitudinal axial direction on the steering spindle connection and the intermediate piece. The steering arrangement includes a clamping device that clamps the plug partners to each other in a plugging position.
Abstract:
A steering arrangement includes a steering spindle and a steering coupling provided with a fork crown bearing a connecting element that connects an end of the steering spindle to the steering coupling in the form of a plug connection. To enable the combined steering spindle and steering coupling ends to be connected to each other in the correct relative position and thus to be able to prevent a defective assembly, the steering spindle end and the connecting element are coaxial plug partners on ends facing each other, by means of at least one tongue and groove guide element pair that provides a torque-transmitting priority control. The at least one groove and/or the at least one tongue of the guide element pair is molded on the interior of the shaft. A clamping device clamps the plug partners against each other in a plugging position so that they cannot come loose.
Abstract:
An expandable key for being received in registering channels which form a keyway in a hub member and a shaft member. The key includes an expansion member composed of a plurality of parallel fillets which collectively have a rectangular cross sectional peripheral outline and a bore extending longitudinally therebetween, and at least one clamp body positioned within the bore. A threaded tensioning member extends through the bore of the fillets and threadedly engages a bore in the clamp body, such that upon rotation of the tensioning member the clamp body is drawn into the bore to expand the fillets. The clamp body and the bore of the fillets have interengaging generally flat tapered surfaces which are in the form of a truncated four sided pyramid.
Abstract:
A first shaft provided with a flange having a through bore is coupled to a second shaft provided with a flange having a blind bore aligned with the through bore in the flange of the first shaft using a coupling device including an adapting bolt having an external tapered surface and an axial hole open at the narrower end of the adapting bolt and a cylindrical sleeve element having an internal tapered surface corresponding to the external tapered surface of the adapting bolt, the adapting bolt being within the sleeve element. The coupling device is fitted in the aligned bores so that the narrower end of the adapting bolt is toward the flange of the first shaft and an end surface of the sleeve element is exposed. A tool is fitted in the axial hole in the adapting bolt and a force is applied to the tool tending to displace the adapting bolt relative to the sleeve element in the direction from the wider end of the adapting bolt toward the narrower end thereof.
