Abstract
The utility model discloses an oil filling device of a motor of an electric bicycle, which is arranged on a leading-out shaft of the motor of the electric bicycle. The oil filling device comprises an oil filling channel and an oil filling seat; the oil filling channel is arranged in the leading-out shaft and is a channel which penetrates from the leading-out shaft to the inner part of the motor; the oil filling seat is arranged at the outer end part of the leading-out shaft and comprises a shell and an elastic sealing piece; and the bottom of the shell is communicated with the oil filling channel. The elastic sealing piece can seal the oil filling seat under the normal condition, and can be compressed under the effect of the jacking force of an oil filler, so that oil is filled. In the motor oil filling device of the electric bicycle, the structure is simple, the oil can be conveniently filled for a gear in the motor, and the service life of the motor is prolonged.
Description
Technical field
The utility model relates to a kind of oiling device, particularly a kind of oiling device on the electric bicycle motor with gear reduction function.
Background technology
The electric bicycle that has the gear reduction function, its motor internal is provided with reduction gearing.Reduction gearing need be injected machine oil to it and prevent wearing and tearing behind the operation certain hour.But because motor is a Totally-enclosed-type, and installation is also comparatively complicated in electric motor car, motor can not be taken apart and carry out oiling.The gear of motor internal is through after the operation of certain hour, and its lubricating oil can be because throw away and aging and be gradually reduced to disappearance, so cause the wearing and tearing of gear, thus have influence on the performance and the useful life of whole electric bicycle motor.
Summary of the invention
Goal of the invention of the present utility model is in order to overcome the shortcoming in the above-mentioned background technology, a kind of oiling device of electric bicycle motor to be provided, and can be that gear in the motor injects lubricating oil easily by this oiling device.
Goal of the invention of the present utility model is achieved by the following technical solution.
A kind of motor oiling device of electric bicycle, it is arranged on drawing on the axle of electric bicycle motor, this device comprises oiling passage and oiling seat, described oiling passage is arranged on described drawing in the axle, for always connecting the passage of shaft to motor internal, described oiling seat is arranged on described outer end of drawing axle, described oiling seat comprises housing and elastic sealing element, housing bottom with shown in the oiling channel connection, elastic sealing element under normal circumstances can seal the oiling seat, under the effect that is subjected to oil ejector top power, can be compressed, thereby carry out oiling.
Described elastic sealing element comprises spring that is arranged in the housing and the steel ball that is arranged on the spring top.
The utility model is arranged on motor and draws on the axle, and by making a call to a through hole on the axle and form the oiling passage drawing, simple in structure and improvement cost is low, the oiling seat is under normal circumstances sealed the oil filler point of oiling seat by elastic sealing element, the machine oil that can prevent motor internal leaks outside, when the needs oiling, oil ejector can carry out oiling by elasticity of compression seal, and the oiling operation is very easy.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described.
As shown in Figure 1, the utility model is arranged on drawing on the axle (3) of motor (1), wherein oiling device has comprised oiling passage (4) and oiling seat (5), beaten a through hole that runs through on the axle and formed oiling passage (4) drawing, the oiling channel connection is to the inside of motor, and lubricating oil can enter motor internal oilgear (2) by the oiling passage.Be provided with oiling seat (5) in the outer end of drawing axle.
Oiling seat (5) as shown in Figure 2, comprise oiling seat housing (6), in oiling seat housing, be provided with spring (7), the spring top is provided with steel ball (8), the oiling port of oiling seat is a baffle plate (9), to steel ball (8) play spacing about, prevent that steel ball (8) from ejecting, the central opening of baffle plate (9) is less than steel ball (8) diameter.Steel ball (8) under normal circumstances can seal the oiling seat by the active force of spring (7), oil ejector can head into the oiling seat by the opening of baffle plate, steel ball is depressed into oiling seat inside under the effect that is subjected to oil ejector top power, and the oil filler point of oiling seat (5) is wide open, can carry out oiling.
Claims (2)
1. the motor oiling device of an electric bicycle, it is arranged on drawing on the axle of electric bicycle motor, it is characterized in that this device comprises oiling passage and oiling seat, described oiling passage is arranged on described drawing in the axle, for always connecting the passage of shaft to motor internal, described oiling seat be arranged on described draw the axle the outer end, described oiling seat comprises housing and elastic sealing element, housing bottom with shown in the oiling channel connection.
2. the motor oiling device of electric bicycle as claimed in claim 1 is characterized in that described elastic sealing element comprises being arranged on the spring in the housing and being arranged on the spring top to get steel ball.
