Abstract
The utility model provides a motor output shaft of an electric motorcar. The motor output shaft mainly comprises a power output shaft body at the middle part of a motor, wherein the power output shaft body is divided into two parts, namely a driving shaft and a transmission shaft, and the two independent split type driving shaft and transmission shaft can be movably connected in a dismountable mode. When a transmission mechanism vibrates, the transmission shaft vibrates together with the transmission mechanism, and the vibration can be effectively eliminated through a gap between a lug of a flat structure and a notch to ensure that the driving shaft in the motor is rotated smoothly, so that the service life of a bearing and a sealing ring of the motor is prolonged.
Description
Technical field
The utility model relates to motor output shaft, the motor output shaft of a kind of electric motor car specifically.
Background technology
Motor output shaft in the market is an integral type, is rotor core and extends to the driven wheel on the driving shaft always or extend to the input gear on the speed changer.Adopt the output shaft of this structure, because the output shaft of motor itself is longer, requirement on machining accuracy is higher; Moreover when drive system produces when vibration in the course of the work, the output shaft of motor is also along with vibration, aggravated the sealing ring on the output shaft of motor, the wearing and tearing of bearing.
In view of this, to the problems referred to above, propose a kind of reasonable in design and can improve the motor output shaft of the electric motor car of above-mentioned disappearance.
The utility model content
The purpose of the utility model is to provide a kind of motor output shaft of electric motor car, can effectively eliminate vibration, guaranteeing the smooth-going rotation of driving shaft in motor, thus the useful life of having improved the bearing and the sealing ring of motor.
In order to reach above-mentioned purpose, the technical scheme that the utility model proposes is: a kind of motor output shaft of electric motor car mainly comprises the power output shaft body that motor is middle; Said power output shaft is divided into two parts, is respectively driving shaft and power transmission shaft, and these two independent split type driving shafts and power transmission shaft adopt dismountable activity connected mode.
Be wound with the rotor winding on the said driving shaft, power transmission shaft and transmission structure machine are in transmission connection; Be provided with sealing ring between said driving shaft and the motor.
Said driving shaft and offer flat recess with end face that power transmission shaft will be connected; Corresponding and connect on the end face of power transmission shaft of this flat recess and offer projection; Said power transmission shaft connects through the recess that projection inserts on the driving shaft.
Said power transmission shaft and offer flat recess with end face that driving shaft will be connected; Corresponding and connect on the end face of driving shaft of this flat recess and offer projection; Said driving shaft connects through the recess that projection inserts on the power transmission shaft.
Said recess and projection are provided with along the diametric(al) of axle.
Compared to prior art; This split type output shaft of the utility model; When vibration took place transmission mechanism, power transmission shaft was also being followed and is being vibrated, and can effectively eliminate vibration through the projection and the gap between the recess of flat structure; Guaranteeing the smooth-going rotation of driving shaft in motor, thus the useful life of having improved the bearing and the sealing ring of motor.
Description of drawings
Fig. 1 is the structural representation of main shaft of the motor output shaft of a kind of electric motor car of the utility model;
Fig. 2 is the structural representation of power transmission shaft of the motor output shaft of a kind of electric motor car of the utility model.
Among the figure: 1, motor; 2, driving shaft; 3, recess; 4, sealing ring; 5, power transmission shaft; 6, projection.
Embodiment
Detailed description of relevant the utility model and technology contents, conjunction with figs. are explained as follows, yet accompanying drawing only provides the usefulness of reference with explanation, are not to be used for the utility model is limited.
Please with reference to shown in the figure, a kind of motor output shaft of electric motor car mainly comprises the power output shaft body in the middle of the motor 1; Said power output shaft is divided into two parts, is respectively driving shaft 2 and power transmission shaft 5, these two independent split type driving shafts and the dismountable activity connected mode of power transmission shaft employing.Said driving shaft 2 and said driven shaft 5 link together through flat structure.Wherein be wound with the rotor winding on the driving shaft, driven shaft and transmission structure machine are in transmission connection, and are provided with sealing ring 4 between driving shaft and the motor.Have the recess 3 of flat structure in the end of driving shaft 2, on driven shaft, be provided with the projection 6 that matches with said recess.Likewise, also can on the driving shaft projection be set, recess is set on driven shaft.Recess and projection are along the diametric(al) setting of axle.This split type output shaft of the utility model; When vibration takes place in transmission mechanism; Power transmission shaft is also being followed and is being vibrated; Vibration can be effectively eliminated in projection and the gap between the recess through flat structure, guaranteeing the smooth-going rotation of driving shaft in motor, thus the useful life of having improved the bearing and the sealing ring of motor.
The above is merely the preferred embodiment of the utility model, and non-in order to limit the claim of the utility model, the equivalence of the patent spirit of other utilization the utility model changes, and all should all belong to the claim of the utility model.
