Title: Rolling ball bearing
Inventor: IKEDA NORIFUMI
IPC: F16C33/32
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To improve an acoustic life and reduce a rotation torque. SOLUTION: Contact surface stress is reduced, seizure is prevented for a long term, and the surface is prevented from roughing by setting a radius of curvature on an inner wheel raceway surface to more than 50.5% and less than 52% of a ball diameter. An area of the contact surface is reduced to reduce a differential slide, and low torque and long life is realized by setting a radius of curvature on an outer wheel raceway surface to more than 53% and less than 55% of the ball diameter. Since a rolling element is made of ceramics, inertia is reduced to reduce slide and abrasion, whereby friction is reduced and low torque is realized. Durability in a high temperature area is improved by using ester oil as a base oil of a pre-charged grease. Since a retainer is made of synthetic resin, torque can be reduced due to a light weight, and generation of heat and abrasion powder is prevented thereby enhancing a long life.

Abstract: PROBLEM TO BE SOLVED: To reduce an attenuation action against the propagation of bending waves by making at least one of two surface layers and a central layer to have a conductive area and making the conductive areas undergo conductive coupling to the wire of a voice signal source and each connection terminal of each drive system. SOLUTION: Two surface layers 12.1 and 12.2 are connected to a central layer 11 at two surfaces of the layer 11 facing each other. A vibration coil holder 14 is inserted into the layer 11, its free end 15 projects from a panel 10 and has a vibration coil 16 and the holder 14 and the coil 16 are connected to a drive system. Line ends that are necessary to feed the coil 16 are respectively connected to conductive areas 17.1 and 17.2 and are respectively constituted of electric wires passing between the lower surface layer 12.2 and the layer 11. Because solid contact is improved if the electric wires are constituted of the conductive areas in the form of conductive foil and laminated on a side facing the layer 11 of the layer 12.2, it becomes unnecessary to perform processing that supports the electric wires with elastic material.
