Abstract
The utility model relates to a novel bearing system for an electric fuel pump. The system comprises a pump cover nail, a rotating shaft, a porous bearing and a damper, wherein the damper is provided with a spring and a top ball which make the rotating shaft generate axial force. The spring and the top ball minimize the vibration of the rotating shaft, thereby protecting a motor. The system is advantageous in that a rotor and a stator can be accurately positioned during operation of a motor, the friction coefficient is lowered, noise is reduced and efficiency is improved.
Description
Technical field
The utility model relates to a kind of motorcar electric fuel pump, particularly a kind of new bearing system in the electric fuel punp.
Background technique
Before the present utility model, lack a cover complete and effective bearing system in the automobile fuel pump, when easily causing the motor running between stator and the rotor location inaccurate, cause problems such as friction is violent, noise is big, thereby cause shorten serious wear the working life of the pump housing.
Summary of the invention
The purpose of this utility model is exactly design for the above-mentioned defective that solves prior art a kind of: low friction, low noise, high efficiency bearing system.
The technical solution of the utility model is: electric fuel punp has comprised a kind of new bearing system; this system comprises pump cover nail, rotating shaft, oil-impregnated bearing and damping device; it is characterized in that described damping device being provided with makes rotating shaft produce the spring and the top ball of axial force; reduce the vibration of rotating shaft, reached the purpose of protection motor.
Advantage of the present utility model and effect be that the utility model makes and can accurately locate between motor when running stator and the rotor, the coefficient of reducing friction, reduces noise, raises the efficiency.
Description of drawings
Fig. 1---the utility model generalized section
Embodiment
As shown in Figure 1, it includes pump cover nail 1, rotating shaft 3, oil-impregnated bearing 5 and damping device the utility model, and damping device being provided with makes rotating shaft produce the top steel ball and the spring 6 of axial force.
As shown in Figure 1, machine shaft 3 one ends withstand pump cover nail 1, one end and withstand top steel ball and spring 6, are fixed in the pump housing with this.Its shaft 3 bottoms be designed to a gradient, reduced the area of contact with pump cover nail 1, thereby reduced friction coefficient, reduce noise, increase the service life; Secondly, rotating shaft 3 the other ends are withstood by top steel ball and spring 6, to reduce the vibration of rotating shaft 3, reach the purpose of protection motor.
Protection domain of the present utility model is not limited only to the description of present embodiment.
