Abstract
The utility model discloses a flywheel structure of cycling equipment. The flywheel structure of the cycling equipment comprises a magnetic control wheel, a central spindle, bearings and bearing pedestals; a through hole is formed in the center of the magnetic control wheel, and the central spindle penetrates the central spindle; the central spindle and the magnetic control wheel are assembled into a whole in a transition fit manner; bearings are respectively arranged on the bearing pedestals to form supporting seats for the central spindle, and are respectively arranged at both sides of the through hole of the magnetic control wheel; ring slots are formed in the central spindle so as to install locating lock rings. The flywheel structure disclosed by the utility model has the advantages that a driven wheel and a belt wheel which are matched are smaller in axle; the transmission speed ratio is maximized; the rotational inertia is large; under the condition that the flywheel weight is not increased, the best practical effect is achieved, and the cost is reduced.
Description
Technical field
The utility model discloses a kind of body-building cycle flywheel structure, divides and belongs to body-building cycle flywheel technical field by International Patent Classification (IPC) (IPC).
Background technology
Exercycle, also referred to as cycle ergometer, can be adjusted the intensity while moving, plays the effect of body-building, is mainly to promote cardiovascular motion by the motion of health long period, suitable intensity, strengthens heart and lung functions, thereby improves the physique of human body.The flywheel structure of existing exercycle otherwise be that flywheel shaft core is fixed, flywheel rotates, or flywheel shaft core and flywheel rotate together with fixing by bolt or key, structure is comparatively complicated, assembling trouble, the driven pulley matching with flywheel is larger, rotary inertia is little.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, safe and reliable body-building cycle flywheel structure.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of body-building cycle flywheel structure, comprises magnetic control wheel and axle core, magnetic control wheel central through hole and being run through by axle core, and axle core and magnetic control wheel interference fits are assembled into one.
Further, flywheel structure also comprises bearing and bearing block, and bearing is arranged on and on bearing block, forms the supporting seat of axle core and be placed in magnetic control wheel through hole both sides, and axle core is provided with annular groove with putting installation positioning retainer ring.
Further, described bearing block and bearing fit side face are provided with some axial notches.
Further, described magnetic control wheel both sides are provided with left and right riser, and by screw connection corresponding to bearing block, two risers are provided with hole clipping to be run through and pass through for axle core.
Further, described magnetic control wheel periphery is provided with the magnet frame of arcuation magnet and cooperation.
The driven pulley Pulley shaft that the utility model matches is less, and transmission speed ratio maximizes, and the belt pulley external diameter of driven pulley is less, if under the constant prerequisite of driving wheel external diameter, corresponding rotary inertia increases, inertia is large, be issued to Best Practical effect not increasing flywheel weight situation, cost-saving.
Brief description of the drawings
Fig. 1 is the utility model exploded view.
Fig. 2 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to Fig. 1 and Fig. 2, a kind of body-building cycle flywheel structure, comprises magnetic control wheel 1 and axle core 7, magnetic control wheel 1 central through hole and being run through by axle core 7, axle core 7 is assembled into one with magnetic control wheel 1 interference fits.Flywheel structure also comprises bearing 5 and bearing block 4, and bearing 5 is arranged on and on bearing block 4, forms the supporting seat of axle core and be placed in magnetic control wheel 1 through hole both sides, and axle core 7 is provided with annular groove, with putting, positioning retainer ring 3 is installed.Bearing block 4 is provided with some axial notches with bearing fit side face.Be provided with left and right riser 2L, 2R in magnetic control wheel 1 both sides, by screw 6 connection corresponding to bearing block, two risers are provided with hole clipping to be run through and passes through for axle core.The magnet frame 9 that is provided with arcuation magnet 8 and coordinates in magnetic control wheel 1 periphery.
The utility model and existing body-building equipment structure difference:
1, driven pulley Pulley shaft is less, and transmission speed ratio maximizes;
2, rotary inertia is large, and inertia is large, is issued to Best Practical effect not increasing flywheel weight situation, cost-saving;
3, magnetic control wheel and axle core interference fits assemble up, and are one, and bearing, flywheel, axle core three position are broken through traditional structure.
Above record, only, for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
