Estimating the term…
There are provided a spherical bearing and a method for manufacturing the same, in which both of a ball bearing section and a ball section made of metal can make light and smooth swinging and rotary motions for a long period of time without biased wear and seize-up of those members even if the solid bodies of them can contact with each other due to a discontinuous oil film under a heavy load. A resin liner that contacts the ball section of the inner member in a sliding relationship is embedded in the ball bearing section, and a resin sliding contact surface provided by the resin liner and the metal sliding surface are adjacent to each other without any gap to form a sliding contact surface at the bearing section.
A spherical bearing having an inner member with a ball section and an outer member with a ball bearing section for enclosing and holding the ball section of the inner member to be coupled with the inner member such that it can be swung or rotated relative to the inner member, the ball bearing section of the outer member having a metal sliding contact surface in a concave spherical configuration that is in contact with the ball section of the inner member in a sliding relationship and that undetachably encloses and holds the ball section, which comprises:
A method for manufacturing a spherical bearing having an inner member with a ball section and an outer member with a ball bearing section for enclosing and holding the ball section of the inner member to be coupled with the inner member such that it can be swung or rotated relative to the inner member, which comprises the steps of:
