Kind.
The utility model also proposed a kind of speed-changing chain with the gear ring with the assembling structure of turriform cylinder,
Including：One end is equipped with the wheel hub of disc, and the outer circle of the disc is adapted to company with the inner circle of the big end gear ring in the assembling structure
Connect, the connection of the disc of the adjacent gear ring on the disc and assembling structure, the small end gear ring in the assembling structure with it is described
The outer circle of wheel hub connects.
Preferably, the disc is integrated making forming with wheel hub or split production reassembles forming.
Preferably, the disc is equipped with lightening hole.
Preferably, the endoporus of the wheel hub is provided with spline, and loss of weight annular groove is additionally provided in the middle part of wheelboss inner hole.
Preferably, the outer circle of the disc and the connection of the inner circle of big end gear ring be is threadedly coupled and/or welds, interference company
The one kind for connecing and welding, be keyed.
Preferably, the connection of the disc disc adjacent with big end gear ring is riveting and/or welding, screwing
It is a kind of.
Preferably, the small end gear ring and the connection of the wheel hub outer circle be at least be threadedly coupled, be keyed, riveting,
One kind of welding or interference connection.
Gear ring and tower are provided separately making by the utility model, and gear ring is separately fabricated, can substantially reduce teeth portion
The difficulty of manufacture, while support section being designed as to the tower form of an entirety, but with very high intensity with it is prodigious just
Degree.And tower may is with the material of lightweight to be manufactured, thus under the premise of ensureing high intensity high rigidity and lighter quality,
The craftsmanship of manufacture can be improved and reduce cost.The utility model is simple in structure, easy making process, easy to utilize.
