Abstract
The utility model relates to a ratchet wheel for a variable speed device, which belongs to a ratchet gear on an inner variable speed device of a bicycle; the variable speed ratchet gear comprises supporters of gear teeth and a plurality of gear teeth; the center of each of the supporters of gear teeth is provided with a shaft hole; the gear teeth are uniformly fixed on the outer wall faces of the left end of each of the supporters of gear teeth with an integral structure; a plurality of inner ratchets or brink ratchets are arranged on the inner wall of a shaft hole of the left end part of each of the supporters of gear teeth in a circular shape. The utility model is combined by assemblies such as ratchet pawls, etc. and is used for inner variable speed devices for bicycles. The utility model has the advantages of simple operation, flexible gear shifting, small chain wheels, high durability, etc.
Description
The utility model relates to a kind of gear, particularly relates to a kind of ratchet gear that is used on the internal speed variator of bicycle.
At present its change-speed box of bicycle of producing is to adopt to be contained in variable gear assembly that each tooth radius on the axis varies in size and to cooperate with chain and finish speed change, there are a lot of shortcomings in this speed change, exposed outside as the variable gear assembly, promptly not attractive in appearance, fragile again, the variable speed operation underaction, speed change retaining is time few etc.
The purpose of this utility model provides a kind of variable-speed motor ratchet gear that adapts to the variable speed bicycle needs.
The purpose of this utility model adopts following technical proposals to realize, that is:
The variable-speed motor ratchet gear, constitute by teeth supporting mass and a plurality of teeth, the teeth supporting mass is made up of for three sections left part, center section part and right part, and outside wall surface is the face of cylinder, three sections is an integral structure, the descending arrangement of its diameter, and a plurality of teeth are distributed on the left part outside wall surface of teeth supporting mass, and be an integral structure, there is axis hole the center of teeth supporting mass.
The avris of the axis hole of described teeth supporting mass left part has a plurality of interior ratchets, and a plurality of interior ratchets are arranged in the form of a ring, and teeth directional is vertical with axis hole.
Also can be a plurality of avris ratchets on the inwall of the axis hole of described teeth supporting mass left part, a plurality of avris ratchets be arranged in the form of a ring, and teeth directional is parallel with axis hole.
On the outside wall surface of the right part of described teeth supporting mass outside thread is arranged.
One location pin-and-hole is arranged on the right side, stage casing of described teeth supporting mass.
The variable-speed motor ratchet gear can be used as the variable gear that the internal speed-changing of variable speed bicycle is used, and also can use on other variable-speed motor.A plurality of speed change ratchet gear suits and are contained on the axis of inner speed change bicycle together, with bevel gear component, or unit construction such as pawl assembly, constitute the change-speed box of inner speed change bicycle.Advantages such as that this variable speed bicycle has is simple to operate, stable performance, sprocket wheel is little, gear is many, shift speed change is convenient.
Fig. 1 is a kind of embodiment scheme drawing of variable-speed motor ratchet gear, and Fig. 2 is second kind of embodiment scheme drawing of variable-speed motor ratchet gear, and Fig. 3 and Fig. 4 are respectively the right elevation of Fig. 1 and Fig. 2.The utility model is described in further detail below in conjunction with accompanying drawing.
