A tolerance ring having a first axial end, a second axial end, and a central axis, the tolerance ring including an annular band; a plurality of protrusions, all of the plurality of protrusions extending from the annular band; and a guide portion extending from the annular band towards the first axial end of the tolerance ring, where the guide portion includes a guide surface that is curved in an axial section.

A tolerance ring has a hollow band with outwardly extending corrugated protrusions forming waves that engage an inner surface of a bore of a housing. At one end of the tolerance ring is an inwardly flared guide surface extending axially and radially from the band. The guide surface acts as a tapered entrance to assist the insertion of a shaft into the hollow band during assembly of the ring into the bore of the housing.

A method of inserting a pin in a bore of an article may include first providing an article with a bore, the bore having an inside diameter. The method may then include providing a pin having a hollow body, the hollow body having a diameter with a profile with a pattern of voids. The method may then include applying an axial force on an end of the hollow body to cause the diameter of the pin to reduce in size to a point where the diameter of the pin is less than the inside diameter of the article. The method may further include aligning the pin inside of the bore of the article, and then removing the axial force on the end of the hollow body.

An assembly structure of a tubular body and a handle includes a tube, two connecting members, a handle, a position-limiting member and a blocking member. The tubular body has at least one pair of insertion holes. Each connecting member has a concave surface with a positioning post. The connecting members are mounted on the outer periphery of the tubular body with the positioning posts inserted into the insertion holes respectively. The handle is connected to a coupling base. The coupling base has a mounting hole and is mounted around the connecting members. The position-limiting member and the blocking member are provided at two opposite ends of the connecting members respectively and abut against two opposite ends of the coupling base respectively. The assembly structure allows the handle to be easily and securely mounted and positioned on the tubular body.

A product and method for assembling multiple components using an interference fit. An assembled product includes a first component, with a second component configured to mate with the first component so that the second component is removable from the first component for a positional adjustment. A third component is configured to mate with the first component and to be engaged therewith by a first interference fit. The first interference fit is configured to impart a resultant reaction in the first component that creates a second interference fit between the first and second components.

A tolerance ring has a band with outwardly extending corrugated protrusions forming waves that engage an outer surface of a shaft. At one end of the tolerance ring is an inwardly flared guide surface extending axially and radially from the band. The guide surface acts as a tapered entrance to a bore of a housing to assist during assembly.
