Abstract
A small flywheel fit for a small-wheel-diameter wheel comprises a flywheel shell, a reversible gear, rolling needles and a bearing. The small flywheel fit for the small-wheel-diameter wheel is characterized in that the flywheel shell is arranged on the periphery of a chain wheel gear, the middle surface of the flywheel shell is tubular, the bearing is embedded in an inner hole on one face of a flywheel chain wheel gear, reversible teeth are arranged at one end of the reversible gear, a thread is arranged at the other end of the reversible gear, the middle portion of the reversible gear is a cylinder, a semi-circular groove is reserved on one side of the cylinder, and a through hole is reserved in the middle of the reversible gear. On reversible teeth of the reversible gear, grease is plastered on gear cavities, the rolling needles are placed, and the flywheel shell embedded with the bearing is sleeved to form the small flywheel fit for the small-wheel-diameter wheel. A thread is tapped on the central hole of the small-wheel-diameter wheel, and the end, with the thread, of the reversible gear is connected in the threaded hole at the center of the small-wheel-diameter wheel in a screwed manner.
Description
Technical field
The present invention relates to a kind of flywheel, particularly a kind of small flywheel coordinating small diameter wheel.
Technical background
Can see in the market, be generally the flywheel coordinating ordinary bicycle.And for PU wheel and the small diameter wheel of aluminium die casting, being difficult to seek suitable flywheel, the design people once formerly designed the small flywheel of PU wheel, but performance and stability is unsatisfactory and purposes is also only limitted to PU and takes turns.
Summary of the invention
Object of the present invention, be to provide a kind of be both applicable to taking turns with PU coordinate, also applicable with the small diameter wheel of aluminium die casting coordinate---coordinate the small flywheel of small diameter wheel.The object of the present invention is achieved like this, coordinate the small flywheel of small diameter wheel, comprise flywheel hub, fall along tooth, needle roller and bearing, it is characterized in that: flywheel hub is the periphery of sprocket teeth, middle one side is tubulose, a bearing is studded with in an endoporus of flywheel hub sprocket tooth, a headband along tooth has down along tooth, other end along tooth is threaded, a cylinder in the middle part of suitable tooth, the side of cylinder is with a semi-circular recesses, there is a through hole centre along tooth, falling along on the suitable tooth of tooth, mark of mouth place is spread butter, and put needle roller, put the flywheel hub studding with a bearing again, just synthesize the small flywheel that coordinates small diameter wheel, by the center hole tap out of small diameter wheel, again with being fastened in the tapped hole at small diameter wheel center along screwed one of tooth, small diameter wheel counterbore is on one side corresponded to along the cylinder of tooth and along falling along the edge perforate of the semi-circular recesses on tooth cylinder facing to small diameter wheel counterbore by falling, make the semicircle orifice at small diameter wheel counterbore edge and fall become a complete circular hole along the semi-circular recesses on tooth cylinder and squeeze into a pin in this circular hole, make down suitable tooth strong bonded in small diameter wheel center.
The invention has the beneficial effects as follows: the present invention can take turns with PU and be connected cooperation easily, and also can be connected cooperation easily with the small diameter wheel of aluminium die casting, purposes is more extensive, for the wheel miniaturization promoting recreation vehicle and recreational vehicle, there is positive role.
Accompanying drawing explanation
Fig. 1 is that the present invention constructs outline drawing
Fig. 2 is structure side pseudosection of the present invention
Fig. 3 is structure principle chart of the present invention
Fig. 4 is that the present invention falls along tooth figure
In figure: 1-flywheel hub, 2-fall along tooth, 3-needle roller, 4-bearing, suitable tooth 2 of wherein falling also comprises: 21-fall along tooth, 22-screw thread, 23-cylinder.
Embodiment
According to Fig. 1, Fig. 2, Fig. 4, the small flywheel of described cooperation small diameter wheel, comprises flywheel hub 1, falls along tooth 2, needle roller 3 and bearing 4;
Described flywheel hub 1 is the periphery of sprocket teeth, centre is tubulose, has in a counterbore distinguished with [Dan, counterbore stud with described bearing 4 in described flywheel hub 1 [Dan by a headband of sprocket teeth.
