Abstract: A rotational-part supporter has a structure in which one of either an inner part or an outer part is fixed, and the other one is rotated, and a main rotational shaft lies between the inner and outer parts. A revolving speed below a revolving speed based on a lubrication lifetime predicted for each rotational bearing (3) is stored in a memory (61) disposed in the lubricant supply controller (6). When a revolving speed obtained by actual rotation coincides with the stored revolving speed in the rotational bearing (3) after supplying the lubricant, the controller (6) issues a signal indicating that the lubricant should be newly supplied, and thereby a safety operation can be realized.

Abstract: A lagging system for conveyor belt pulleys is provided that allows for significant flexibility in attaching lagging members to the face of the pulleys while also providing improved distribution of the lagging material on the pulley face, and doing this while avoiding the creation of unduly long and circumferentially wide gaps between adjacent lagging members attached on the pulley. The lagging system can include lagging strips having non-linear leading/trailing edges thereof to allow adjacent strips to be attached without the undesired gaps formed therebetween. Preferably, the strips have projecting portions with fitment spaces defined therebetween with the projecting portions being offset on either side of the strip axis so that portions from one strip can be interfit in fitment spaces of an adjacent strip with lagging material or tiles thereon overlapping the lagging material or tiles on the projecting portions of the adjacent strip in the circumferential direction.

For this purpose, the opening is provided with a limiting arrangement, which limits an axially directed movement of lubricating oil from the opening to a predetermined area.

Abstract: A decorative strip for automotive bodies, and more particularly, for steering wheel rings, is formed of a thin vinyl substrate with an adhesive coating on one surface and a decorative design on the other. The surface with the decorative design is covered with a coat made of a clear resin. The strip has a generally arcuate shape so that it fits easily on the steering wheel ring thereby improving its esthetic look. Moreover the strip is elastic so that it can be bent as at is applied to the steering wheel thereby conforming naturally to its radius of curvature and forming a smooth and continuous cover without any ridges or other irregularities. In some instances the strip is formed of several parallel sections to allow the strip to adapt better to the curvature of the wheel ring. The sections may have linear lateral edges or the edges may be serrated to form interlocking profiles as the sections are abutted against each other.

Abstract: A pedal mechanism 20 requires a friction mechanism for producing the force hysteresis in the pedal to ensure the correct, desirable pedal ‘feel’. A pedal arm 18 is pivoted in a housing 24. Friction is produced with a piston 28,128 which is urged by resetting springs 30,32,130,132 into frictional contact with a friction pad 36,136 which is fixed in the housing. Relative angular movement between the pedal 18 and the pad 36,136 when the pedal is depressed causes the point of contact between the pad and the piston 28 to move relative to the housing 24. This movement is resisted by friction between the pad and the piston, and by the springs which have to be compressed to allow the movement to take place. The same springs provided a restoring force to return the pedal to its initial position when it is released.

Abstract: A ratio control for a toroidal-type traction drive comprises toroidal discs defining a toroidal cavity. Traction roller assemblies have pivot trunnions rotatably supporting traction rollers. A ratio control element is provided, which is positionable to establish various ratios between the toroidal discs. A feedback structure is connected to the ratio control element and includes a ratio control valve to hydraulically control the traction roller assemblies, and a cam follower. A feedback cam is provided, which cooperates with the cam follower. A lost motion cam actuator is provided between a predetermined pivot trunnion and the feedback cam to permit limited independent deflected movement of the predetermined pivot trunnion from the pivot axis thereof without requiring corresponding movement of the feedback cam.

Abstract: Projections colliding with constricted portions at the center of hourglass-shaped pin link plates and with constricted portions at the center of hourglass-shaped roller link plates are provided at an annular resilient body. When a roller chain starts to mesh with a sprocket, constricted portions at the centers of hourglass-shaped link plates of the roller chain can be pushed radially outwards from the sprocket by the projections of the resilient body, vibrations occurring at the roller chain meshing with the sprocket can be made small, vibrations at each part of the roller chain can be made small, collision speed when rollers of the roller chain collide with teeth bottoms of the sprockets can be reduced, and the generation of noise can be suppressed. Moreover, because hourglass-shaped link plates are used, the roller chain can be made lighter than when flat oval shaped or oval shaped link plates are used.
