Abstract

(57) [Abstract] [Objective] The present invention relates to a device for mounting a generator on a wheel of a bicycle. The object of the present invention is to easily mount a rotor and a stator of a generator at appropriate positions without adjusting other members. To be able to do so. [Structure] A rotor of a generator is screwed to a screw portion for mounting a band brake formed on the outer periphery of one side of a rear wheel hub, and the opening of the rotor is screwed to a fixed shaft to fix a ball push of a hub end bearing. The lock nut is fixed to the screw part so that it is flush with the outer surface of the lock nut that locks to the shaft, and the generator stator is inserted into the fixed shaft and the outer surface of the lock nut that fixes the ball push of the bearing is fixed. A device for attaching a generator to a bicycle wheel, which is in contact with the stator and is further fixed to the fixed shaft by another lock nut.

[Industrial applications]

 The present invention relates to a device for mounting a generator on a bicycle wheel.

[0002]

[Prior art]

 The applicant of the present application, as shown in Japanese Utility Model Application Laid-Open No. 53-61012, has a hub bearing on both sides of which a generator rotor is screwed onto a band brake mounting screw formed on the outer periphery of one side of a bicycle rear wheel hub. Of the power generator to the bicycle wheel by adjusting the ball pushing position of the section, abutting and locking the stator on the outer surface of the lock nut of the ball pushing, and mounting the magnet of the rotor and the coil of the stator so as to face each other. I devised a mounting device.

[0003]

[Problems to be solved by the device]

 A bicycle wheel has bearings formed on both sides of a spoke-attached hub, and is assembled by pressing a ball push screwed on a fixed shaft against the ball of the bearing with proper pressure. In the above-mentioned prior art, the rotor is screwed to the band brake mounting screw formed on the outer circumference of the bearing on one side of the hub, screwed and fixed to the final position, and the ball of the bearing screwed to the fixed shaft according to this rotor. Since the position of the push is adjusted in the axial direction so that the stator coil and the rotor magnet face the proper position, it is difficult to make the pushing force of the ball pushing the bearing balls proper. There was a problem.

[0004]

[Means for Solving the Problems]

 The present invention is intended to solve the above-mentioned problems, and a rotor of a generator is screwed into a screw portion for mounting a band brake formed on the outer periphery of one side of a rear wheel hub, and an opening surface of the rotor serves as a fixed shaft. Lock the ball push of the hub end bearing screwed into the fixed shaft with the lock nut so that it is flush with the outer surface of the lock nut, and insert the generator stator into the fixed shaft to insert the generator stator into the fixed shaft. It is characterized in that the ball push is brought into contact with the outer surface of the lock nut which is fixed, and further the stator is fixed to the fixed shaft by another lock nut.

【Example】

 Reference numeral 1 is a fixed shaft of a bicycle rear wheel, 2 is a hub fitted to the outer circumference of the fixed shaft 1, and spokes 4 are attached to the collars 3 on both sides. A ball 6 is arranged on the bearing portion 5 at the outer end thereof, and a ball push 7 is screwed into a screw portion 8 of the fixed shaft 1, and the ball push 7 is fixed at a proper position by a lock nut 9. . A rotor 11 of a generator is screwed to a screw portion 10 for screwing a band brake to the outer periphery of one side of the hub 2, and an opening surface 11a thereof is flush with the outer surface AA of the lock nut 9. And fix it with the lock nut 12.

Next, the stator 13 of the generator is inserted into the fixed shaft 1, and the lock nut fixing the ball push 7 at the center of the inner plate 14a of the central overlapping portion of the yoke 14 enclosing the coil 17. 9 is formed, the recess 15 is fitted to the outer periphery of the lock nut 9, and the outer plate 14b covering the recess 15 is brought into contact with the outer surface of the lock nut 9. At this time, the magnet 18 of the rotor 11 and the coil 17 of the stator 13 are properly positioned axially opposite each other with a predetermined gap. Next, the stator 13 is pressed and fixed to the outer surface 9a of the lock nut 9 with the lock nut 16 screwed onto the fixed shaft 1.

Next, the operation will be described. When the rear wheel rotates, the hub 2 rotates along the ball push 7 via the ball 6. The rotor 11 also rotates together, and the coil 17 generates electricity.

[Effect of device]

 According to the present invention, the rotor of the generator is screwed into the screw portion for mounting the band brake formed on the outer periphery of the rear wheel hub on one side, and the opening surface of the rotor is screwed into the fixed shaft. Lock the push to the fixed shaft Lock the screw with the lock nut so that it is flush with the outer surface of the lock nut, and insert the generator stator into the fixed shaft to fix the ball push of the bearing. Since it contacts the outer surface of the nut and further fixes the stator to the fixed shaft with another lock nut, the position of the hub bearing and ball push, which have been properly adjusted once, remains the same, and the rotor It is possible to automatically assemble the rotor and the stator to the proper positions by the simple work of fixing the opening surface flush with the outer surface of the lock nut for pushing the ball, and fixing the stator by abutting and fixing the outer surface of the lock nut. ,assembly Work can be carried out easily and reliable.
