Title:
UNIVERSAL JOINT AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/001880
Kind Code:
A1
Abstract:
Provided are a universal joint having excellent lubricant retaining capability,
having a minimized amount of oozing lubricant components even if the universal
joint is deformed by external force, capable of preventing a lubricant from scattering
from an opening, having long life, manufacturable at low cost, and having excellent
productivity, and a method of manufacturing the universal joint. Rotational
torque is transmitted by engagement between a torque transmission member (6)
and track grooves (4, 5) formed in an outer member (2) and an inner member (3), and
the torque transmission member (6) rolls along the track grooves (4, 5) to move
in the axial direction. A porous solid lubricant (10) is enclosed around the
torque transmission members (6). The porous solid lubricant (10) is a porous
solid material having a lubrication component and resin component as essential
components and formed by foaming and hardening the resin component. The universal
joint has scattering prevention means for preventing the lubrication component
from scattering from the solid material.
