Abstract
The utility model relates to a motor-driven bicycle waterproof electric motor and pertains to the technical field of the power device. The motor mainly arranges in the casing an electric motor shaft, the electric motor stator is arranged on the electric motor and the inside of the electric motor rotor is provided with a magnetic steel and is characterized in that the electric motor shaft on the electric motor bearing module outboard is provided with a porcelain sheet sealing device; the porcelain sheet sealing device adopts a support and fixation porcelain sheet, a latex sealing pad, a group of porcelain sheets, a tablet, a spring, a latex corrugation ring and a support in succession arranged on the electric motor shaft. The utility model has a compact and reasonable structure. As the electric motor shaft is installed with the porcelain sheet sealing device and the porcelain sheet has a small friction coefficient, the friction resistance performance is well and improves working efficiency of the electric motor. The latex sealing pad does not involve in the rotational friction thereby improving the service life of the sealing effect. Thus the sealing performance between the electric motor stator and the rotor has been greatly intensified so that no water enters the electric motor of the motor-driven bicycle even the bicycle runs in the water. The utility model reduces over 80% of damage to the electric motor of the electric bicycle.
Description
Technical field
The utility model relates to a kind of waterproof machine of electric bicycle, specifically is used for electric bicycle, belongs to field of power equipment technology.
Background technology
Before the utility model was made, in prior art, the motor that uses on the electric bicycle mainly was made up of parts such as motor stator, rotor, housing and motor shafts.Motor shaft is installed in housing, and motor stator is installed on the motor shaft, and armature is housed on the motor stator, in the rotor inboard magnet steel is housed, bearing assembly supporting motor axle, and O type rubber seal oil sealing is adopted in the bearing assembly outside.Though the rubber sealing device of this kind structure can play dustproof effect, waterproof effect is very poor, and coefficient of friction is big, and power consumption is serious; Wear resistance is poor, and useful life is short; Therefore, rubber oil sea needs often to change, and 90% owing to the motor internal water inlet causes in the source of damage of motor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of waterproof machine to adopt the potsherd sealing device, and the potsherd coefficient of friction is little, and the antifriction performance is good, can improve motor working efficiency; Rubber gasket does not participate in rotating friction, can improve sealing effectiveness and useful life; Strengthened the sealing property between motor stator and the rotor greatly, electric bicycle motor has been travelled in water also can not intake.
Main solution of the present utility model is achieved in that
The utility model mainly adopts motor shaft is installed in housing, motor stator is installed on the motor shaft, in the rotor inboard magnet steel is housed, bearing assembly supporting motor axle, feature is to adopt on the motor shaft of the motor bearings assembly outside potsherd sealing device is installed, the potsherd sealing device adopts fixedly potsherd of support, and rubber gasket, one group of potsherd, compressing tablet, spring, compressing tablet, rubber crimp ring, support are installed on the motor shaft successively.
Rubber rectangular loop, pad and nut are installed on motor shaft successively, and the rubber rectangular loop is used for the fixing seal of motor shaft and support; Pad, nut are the pressure that is used to adjust spring.
Compared with the prior art the utility model has the following advantages:
The utility model compact conformation, rationally; Because the potsherd sealing device is installed on motor shaft, and the potsherd coefficient of friction is little, the antifriction performance is good, can improve motor working efficiency; Rubber gasket does not participate in rotating friction, can improve sealing effectiveness and useful life; Strengthened the sealing property between motor stator and the rotor greatly, electric bicycle motor has been travelled in water also can not intake, can make the spoilage of electric vehicle motor reduce more than 80%.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
