Background technology
With the development of the society, requirement of the various vehicles for lightweight, high intensity now is higher and higher.At present certainly
Driving carries out loss of weight typically by material lightweight with structure lightened, and lightweight is that have enough with intensity and rigidity
Guarantee premised on, for sports bicycle, what its intensity to speed-changing chain and rigidity had a higher will
Ask.And speed-changing chain is one of most important parts in bicycle, its basic performance requirement is in the certain situation of quality
Under, intensity is the higher the better with rigidity, i.e. specific strength and specific stiffness is the higher the better.
The structure wheel group that the speed-changing chain of bicycle is arranged in parallel for the gear ring of multilayer different-diameter, usually there is two kinds of typical cases
Structure type, a kind of to be punching press gear ring be stacked the speed-changing chain to be formed by riveting（Using SHIMANO as representative）, it is another
Kind is a kind of taper（Or cone pulley）The gear ring that hollow body does the multilayer different-diameter of supporter parallel is arranged on its cylindrical integral type
Sprocket wheel（Using SRAM as representative）.It is more that former product punching press gear ring, which is stacked by riveting and to form the product of speed-changing chain,
Number, often rigidity is smaller with intensity, and bearing capacity is weaker, and heavier mass, but processing technology is good；Latter is taper
（Or cone pulley）Hollow body structure, and be typically to be process by a block of material, thus there is higher intensity and rigidity, at the same time also
With lighter quality.The shortcomings that although this structural advantages is more, poor there is also craftsmanship, and cost is higher, while its is firm
Degree is also than relatively limited.
Therefore, how a kind of light-weight, intensity and rigidity higher are provided, and its process industrial art performance can be improved and can be dropped
The speed-changing chain of its low cost is industry urgent problem to be solved.
The content of the invention
The craftsmanship of existing bicycle variable speed chain wheel is poor, cost is higher in order to solve by the present invention, while its rigidity also compares
Relatively limited technical problem, proposition is a kind of to improve manufacture on the premise of high intensity, high rigidity and lighter quality is ensured
Craftsmanship and reduce the gear ring of cost and the assembling structure and speed-changing chain of turriform cylinder.
The assembling structure of a kind of gear ring proposed by the present invention and turriform cylinder, it includes：Integrally formed stair-stepping tower
Shape cylinder, the vertical parallel gear rings at different levels being fixedly connected on the cylindrical steps at different levels of the turriform cylinder.
Preferably, the gear ring and turriform cylinder step be fixedly connected at least be welding, riveting, be threadedly coupled one
Kind.
The invention also provides a kind of speed-changing chain with the gear ring with the assembling structure of turriform cylinder, it is wrapped
Include：One end is equipped with the wheel hub of disc, and the inner circle of the cylindrical big end gear ring with the assembling structure of the disc is adapted to connection,
The disc of adjacent gear ring on the disc and assembling structure connects, the small end gear ring in the assembling structure and the wheel hub
Cylindrical connection.
Preferably, the disc is integrated making shaping with wheel hub or split production reassembles shaping.
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 with the middle part of wheelboss inner hole.
Preferably, the cylindrical and connection of the inner circle of big end gear ring of the disc for is threadedly coupled and/or welds, interference company
Connect and weld, one kind of key connection.
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 cylindrical connection of the wheel hub be at least be threadedly coupled, key connection, riveting,
Welding or one kind of interference connection.
Gear ring and tower are provided separately making by the present invention, and gear ring is separately fabricated, can substantially reduce teeth portion manufacture
Difficulty, while support section is designed as to the tower form of an entirety, and with very high intensity and very big rigidity.And
Tower may with the material of lightweight to be manufactured, can be with thus on the premise of high intensity high rigidity and lighter quality is ensured
Improve the craftsmanship of manufacture and reduce cost.The configuration of the present invention is simple, easy making process are easy to utilize.
