The invention is mainly applied to the mounting of the stepless speed changer on the rear bracket of the bicycle, and the position change of the axle plate is realized by changing the long and short adapters, thereby being suitable for the mounting of different frames, and being convenient and quick.
Description
Technical Field
The present invention relates to a connecting structure, and more particularly, to a connecting structure of a shaft.
Background
Currently, the high-end bicycle market mainly adopts a stepless speed changer as a speed regulating structure, and has the characteristic of stable and smooth speed regulation. The position width of the rear bracket of the high-end bicycle is generally provided with 2 different standards, but the shaft structure of the general continuously variable transmission is integrated, and the length of the shaft and the relative positions of fixing parts such as a shaft plate, an end cover nut and the like can not be adjusted, so that the rear bracket of the bicycle is suitable for the change of the installation width of the rear bracket of the bicycle. At present, the common practice is to uniformly length the shaft, but when encountering a short standard bicycle support, the appearance of the whole bicycle is influenced, the whole bicycle is easily damaged, time and labor are consumed by subsequent process cutting, and the production efficiency is low.
Disclosure of Invention
The invention aims to: in order to solve the above problems and overcome the above disadvantages, a shaft connection structure is provided which allows the entire transmission to fit the width of the rear bracket mounting portion of the bicycle by replacing the long and short adapters.
The technical scheme is as follows: the utility model provides a shaft connection structure, including cap nut, lock washer, screw thread axle, arbor board, derailleur main shaft, adapter, the adapter is installed on the derailleur main shaft, and derailleur main shaft axial is equipped with the internal thread, and screw thread axle right side axle section and left axle section all are equipped with the external screw thread, and screw thread axle right side axle section and derailleur main shaft threaded connection, screw thread axle collar and the contact of adapter flange end counter bore make adapter axial fixity, and the arbor board is connected with the adapter, cap nut and screw thread axle threaded connection, in order to prevent cap nut loosening, cap nut and screw thread interaxial add lock washer, adapter branch long adapter and short adapter 2 kinds, the boss of long adapter is longer than short adapter boss 5-10mm.
When the rear support of the bicycle is short during installation, the short adapter is used for being installed on the main shaft to screw up the threaded shaft, so that the whole transmission is axially shortened, the shaft plate is fixed on the adapter, the shaft plate is clamped on the rear support of the bicycle in a protruding mode, and finally the cap nut is screwed up.
Similarly, when the rear bracket is long, a long adapter is used for installation.
Further, the long adapter boss is 6mm longer than the short adapter boss.
Further, the shaft plate is connected with the adapter through bolts.
Further, the shaft plate is made of aluminum alloy or alloy steel.
The principle of the invention is as follows: the screw thread shaft replaces an integral long shaft of the original stepless speed reducer, the whole shaft is changed in a certain length through the rotation of the screw thread, and 2 kinds of adapters with different lengths are combined to adapt to 2 kinds of installation size changes in the high-end bicycle frame standard, so that the whole bicycle stepless speed reducer is installed quickly and conveniently.
The beneficial effects are that: compared with the prior art, the invention has the advantages that: according to the invention, the screw shaft replaces the integral long shaft of the original electrodeless speed reducer, so that the inconvenience in installation and operation caused by different frame standards is solved, a set of components can be used for installing 2 different standard frames, the production and management cost of a complete machine manufacturer is reduced, and the convenience in maintenance is improved.

Description of the embodiments
The invention is further illustrated by the following specific examples, which are intended to be illustrative of the invention and not to be limiting of the scope of the invention, since modifications of the invention in its various equivalent to those skilled in the art will fall within the scope of the invention as defined in the claims appended hereto.
A shaft connection structure as shown in fig. 1 includes a cap nut 1, a lock washer 2, a threaded shaft 3, a shaft plate 4, a transmission main shaft 5, and an adapter 6 (long adapter or short adapter). When a frame to be mounted to a frame standard width is required to use a long adapter, a frame to be mounted to a frame standard width is required to use a short adapter. The shaft plate is made of aluminum alloy, the adapter 6 is arranged on the transmission main shaft 5, internal threads are axially arranged on the transmission main shaft 5, external threads are respectively arranged on the right shaft section 301 and the left shaft section 302 of the threaded shaft 3, the right shaft section 301 of the threaded shaft 3 is in threaded connection with the transmission main shaft 5, the threaded shaft 3 is screwed down, and the shaft collar of the threaded shaft 3 is contacted with the counter bore of the flange end of the adapter, so that the adapter is axially fixed. The shaft plate 4 is connected with the adapter 6 through bolts, the cap nut 1 is connected with the threaded shaft 3 through threads, and the lock washer 2 is arranged at the right end of the cap nut 1 and is used for being in contact with a vehicle frame, so that the cap nut 1 is prevented from loosening.
