Abstract
The utility model relates to an internal ratchet gear for special use of speed variators, which comprises a plurality of gear teeth and a plurality of supporters of gear teeth; the gear teeth are uniformly arranged on the outer walls of the supporters of gear teeth and the supporters of the gear teeth are formed into an integral structure; the supporters of the gear teeth are provided with annular bosses; the annular bosses and the supporters of the gear teeth are formed into an integral structure; the inner ring faces of the annular bosses are provided with a plurality of ratchets. The utility model can be combined to other special gears to be made into speed variators which are installed on a center shaft of a bicycle to become an inner speed change bicycle of a center shaft. The bicycle has the advantages of flexible speed change, firmness, high durability and beautiful appearance.
Description
The utility model relates to a kind of ratchet gear, particularly relates to a kind of ratchet gear of change-speed box use of axis inner speed change bicycle.
China is maximum in the world bicycle selling market, ten thousand of the about 5000-6000 of annual sales, and wherein the about 1000-1200 of variable speed bicycle sales volume is ten thousand.Present variable speed bicycle is located at the exterior variable gear assembly of axis by an assembling, controls by backguy and realizes speed change.This speed change is sensitive inadequately, and fragile.For addressing the above problem, I have designed a kind of axis inner speed change bicycle, and the variable gear of this variable speed bicycle does not expose, speed change sensitivity, sturdy and durable.
The purpose of this utility model provides the inner ratch gear that a kind of axis inner speed change bicycle change-speed box is used.
The purpose of this utility model realizes by following technical proposals, that is:
The special-purpose inner ratch gear of change-speed box comprises a plurality of teeth and teeth supporting mass, and a plurality of teeth evenly are arranged on the outer wall of teeth supporting mass, and with the teeth supporting mass be an integral structure, a plurality of ring-shaped distributed ratchets are arranged on the inner ring surface of teeth supporting mass.
Above-mentioned teeth supporting mass has annular boss, and annular boss and teeth supporting mass are an integral structure, and a plurality of ring-shaped distributed ratchets are positioned on the inner ring surface of annular boss, and with annular boss be an integral structure.
The outside wall surface of above-mentioned teeth supporting mass is interior inclined-plane.
The outside wall surface of above-mentioned ring tooth tooth supporting mass is outer inclined-plane, and annular boss is arranged on the right side, and annular boss and ring tooth tooth supporting mass are an integral structure, and a plurality of ring-shaped distributed ratchets are positioned on the inner ring surface of annular boss.
The utility model cooperates with other dedicated gear, and the change-speed box of making is installed on the bicycle middle shaft, can realize the axis internal speed-changing of bicycle, and not only speed change is flexible, and is sturdy and durable, and can keep the aesthetic appearance of bicycle.
Fig. 1 is the structural representation of a kind of embodiment of the present utility model, and Fig. 2 is the left view of Fig. 1, Fig. 3, Fig. 4, Fig. 5 be respectively of the present utility model second, third, the structural representation of the 4th kind of embodiment.Fig. 6, Fig. 7, Fig. 8 are respectively the left views of Fig. 3, Fig. 4, Fig. 5.The utility model is described in further detail below in conjunction with accompanying drawing.
