Abstract
The utility model relates to a novel harmonic reducing mechanism for an electric bicycle, the technical proposal is that the motor rotor is directly fixed on the external diameter of the harmonic generator and integrates into a body based on the motor bicycle harmonic reducing mechanism, the motor rotor and the harmonic flexible wheel are directly supported by the centre shaft of the bicycle at the same time omitting the harmonic flexible wheel sleeve that is located in the prior harmonic reducing mechanism. Omitting the harmonic flexible wheel sleeve, the utility model increases the radial space of the motor, thereby the axial size of the motor is compressed, and the whole axial size of the driving motor is compressed. The utility model omits the harmonic flexible wheel sleeve, which ensures the simpler structure, the better structure rigidness, the more convenient installation and the lower cost.
Description
Affiliated technical field
The utility model relates to a kind of Electrical Bicycle new harmonic speed reduction gearing.
Background technology
" the Electrical Bicycle harmonic reduction mechanism " of inventor's invention obtained to grant patent on August 3rd, 2005, and the patent No. is ZL 2,004 2 0020086.6.After in actual applications improvement being tested in this design, harmonic generator, harmonic wave flexbile gear have omitted harmonic wave flexbile gear sleeve simultaneously directly by the bicycle middle shaft support, have improved this mechanism performance.
Summary of the invention
The purpose of this utility model is performance, simplified structure, the cost-cutting of the original Electrical Bicycle harmonic reduction of raising mechanism.
The technical scheme that the utility model adopted is: on Electrical Bicycle harmonic reduction mechanism basis, motor rotor directly is fixed on the harmonic generator sleeve outer diameter to become one, with harmonic wave flexbile gear and the bicycle middle shaft axle center that coexists, directly support simultaneously with the harmonic wave flexbile gear by bicycle middle shaft, harmonic wave flexbile gear, harmonic generator are connected by bearings respectively, on bicycle middle shaft, turn round simultaneously, omitted the harmonic wave flexbile gear sleeve in the former harmonic reduction mechanism.
The beneficial effects of the utility model are that omitting harmonic wave flexbile gear sleeve has increased the motor radial space, therefore can compress the electrical motor axial dimension, thereby compress driving machine single-piece axial dimension; Omit harmonic wave flexbile gear sleeve and make structure simpler, structural rigidity is better, and is easier for installation, cost-cutting.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a new harmonic speed reduction gearing constructional drawing, (1) motor rotor, (2) harmonic generator, (3) bicycle middle shaft, (4) harmonic wave flexbile gear among the figure.
Fig. 2 is a former harmonic reduction mechanism constructional drawing, and (5) harmonic wave flexbile gear sleeve is omitted in the utility model among the figure.
The specific embodiment
In Fig. 1, (1) motor rotor drives the harmonic generator one with (2) and (4) harmonic wave flexbile gear directly turns round on (3) bicycle middle shaft simultaneously.
