Abstract
The utility model discloses a hub gear of an electric bicycle motor, which is mounted in a motor provided with a reduction gear, wherein the inner ring of the hub is provided with inner gears, and the inner gears are engaged with outer gears of the reduction gear in the motor. The hub gear is characterized in that the hub is integrated with the inner gears. The hub gear of the electric bicycle motor has the advantages that as the inner gears of the reduction gear are directly arranged on the inner ring of the hub, the possibility of asynchronous rotation of the inner gears and the reduction gear is avoided, and the reliability and the precision of the motor transmission are ensured.
Description
Technical field
The utility model relates to a kind of gear wheel, relates in particular to a kind of integral type gear wheel that is applied to electric bicycle motor.
Background technique
Use electric energy as the electric bicycle of driving force because its moulding is light, can not cause tail gas pollution to be widely used.As a kind of speed per hour traffic tool faster, also higher to the requirement of its speed controlling.The prior electric bicycle motor generally is made up of direct current generator and reducing transmission structure two-part; Reducing transmission structure generally comprises reduction gear and wheel hub; The nested inside of wheel hub has internal gear; The output of direct current generator drives wheel hub and rotates through the interior toothed ring gear engagement inner with being nested in wheel hub of the outer tooth pinion of reduction gear.Toothed ring gear through press fit together in wheel hub and the reduction gear.The shortcoming of this structure is, for guaranteeing the inner accuracy that cooperates of internal gear and wheel hub, to the periphery and inner high, the processing difficulties of circularity requirement of wheel hub of internal gear; Difficulty of processing is big during press fit, easily wheel hub pressure break distortion or both is cooperated insecurely, produces potential safety hazard.
Summary of the invention
The utility model is intended to overcome the deficiency of existing technology, and a kind of gear wheel that can effectively improve the electric bicycle motor of machining accuracy is provided.
For realizing above-mentioned purpose, the utility model provides following technological scheme:
A kind of gear wheel of electric bicycle motor is installed in the motor that is provided with reduction gear, and the inner ring of said wheel hub is provided with internal tooth, and this internal tooth is meshed with the interior reduction gear external tooth of motor, and said wheel hub and internal tooth are one of the forming.
Said wheel hub and internal tooth are preferably integrally formed through casting technique.
The technique effect that adopts the utility model to reach is: the internal tooth of reduction gear is direct and the wheel hub inner ring is integrally formed, improved the machining accuracy of gear wheel, the quality and the working life that help guaranteeing motor product.The reliability of transmission and accuracy.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing 1 makes the utility model and further describing:
The utility model is provided with internal tooth 2 at the inner ring of wheel hub 1, the external tooth engagement of the reduction gear of this internal tooth and motor.Said wheel hub 1 and internal tooth 2 are through casting integrated shaping.
When motor rotates, drive reduction gear and rotate, the external tooth of reduction gear is meshed with the internal tooth 2 of wheel hub 1, the power of motor is exported passed to wheel hub 1, thereby drive wheel hub 1 rotation, makes vehicle driving.
Claims (2)
1. the gear wheel of an electric bicycle motor; Be installed in the motor that is provided with reduction gear, the inner ring of said wheel hub (1) is provided with internal tooth (2), and said internal tooth is meshed with the interior reduction gear external tooth of motor; It is characterized in that said wheel hub (1) is integrally formed with internal tooth (2).
2. the gear wheel of electric bicycle motor as claimed in claim 1, it is characterized in that: said wheel hub and internal tooth are through casting integrated shaping.
