Background technology
Put more effort along with national energy-saving reduces discharging implementation, application of pure electric automobile gets more and more.Driving motor for electric automobile often adopts AC permanent magnet synchronous motor and AC induction motor.Motor is generally arranged on automobile chassis bottom, because supply voltage is higher, if drive motors output shaft extension seals bad meeting cause motor entering water, can produce electric leakage, there is potential safety hazard time serious.
Summary of the invention
The purpose of this utility model is to provide a kind of driving motor for electric automobile and exports shaft extension sealing device, avoids the problems referred to above.
Technical solution of the present utility model is: a kind of driving motor for electric automobile exports shaft extension sealing device, comprise electric motor end cap, it is characterized in that: comprise securing cover plate, adjustment screw, adjustable plate, wavy spring sheet, sealing clamp, the ring-like rubber ring of multilayer and rotating baffle; Wherein, rotating baffle fits closely on the motor output shaft outside electric motor end cap; Sealing clamp, wavy spring sheet, adjustable plate and securing cover plate are sleeved on the motor output shaft outside rotating baffle successively, and securing cover plate is fixed on electric motor end cap, and adjustment screw is arranged on securing cover plate; The ring-like rubber ring of multilayer is arranged in seal groove corresponding to sealing clamp, and outer field ring-like rubber ring contacts with electric motor end cap, and remaining ring-like rubber ring contacts with rotating baffle.
Rotating baffle described in technical solution of the present utility model fits closely in the cannelure of the motor output shaft outside electric motor end cap.
The ring-like rubber ring of multilayer described in technical solution of the present utility model is 4 cylindrical seal rings, and the 4th the cylindrical seal ring in outside contacts with electric motor end cap, and the 1 to 3 cylindrical seal ring of inner side contacts with rotating baffle.
Lubricating grease is filled with between sealing clamp described in technical solution of the present utility model and rotating baffle.
The utility model is owing to adopting by securing cover plate, adjustment screw, adjustable plate, wavy spring sheet, sealing clamp, the ring-like rubber ring of multilayer, rotating baffle, and the driving motor for electric automobile that the electric motor end cap coordinated is formed exports shaft extension sealing device, wherein, rotating baffle fits closely on the motor output shaft outside electric motor end cap, sealing clamp, wavy spring sheet, adjustable plate and securing cover plate are sleeved on the motor output shaft outside rotating baffle successively, securing cover plate is fixed on electric motor end cap, adjustment screw is arranged on securing cover plate, the ring-like rubber ring of multilayer is arranged in seal groove corresponding to sealing clamp, outer field ring-like rubber ring contacts with electric motor end cap, remaining ring-like rubber ring contacts with rotating baffle, thus the adjustable plate regulating sealing pressure of available waveforms spring leaf and band adjustment screw, can ensure that motor all can not be intake with during rotation status static, ensure the safe operation of motor in electric automobile, driving motor for electric automobile degree of protection is improved, cope with bad operating condition.The utility model solves driving motor for electric automobile shaft extension in the static problem with sealing during rotation status, has and better can ensure the performance of product, the consistency in life-span, better save the feature of after cost.The utility model is mainly used in driving motor for electric automobile.
