Abstract
The utility model provides a waterproof structure of a motor for an electric vehicle, which comprises a motor end cover holder and a motor main shaft, wherein the motor main shaft passes through a hole which is formed on the motor end cover holder, the other end of the inner cavity of the motor end cover holder is connected with the motor main shaft through a bearing, and a first rubber sealing ring, a ceramic ring, an ink ring, a second rubber sealing ring and a collar are axially mounted in sequence in the inner cavity of the motor end cover holder. The waterproof structure is characterized in that the outer margin surface of the first rubber sealing ring is in close fit with the inner surface of the motor end cover holder, the inner surface of the bore of the second rubber sealing ring is in close fit with the outer circumference surface of the motor main shaft, and the second rubber sealing ring can rotate along with the motor main shaft. Accordingly, three multi-seal watertight structures are formed between a motor end cover and the motor end cover holder, the motor main shaft and the bearing, so as to achieve excellent sealing and waterproofing effects. Besides, the service life of the motor is prolonged.
Description
Technical field
The utility model relates to the waterproof construction of a kind of electric bicycle with motor, relates in particular to the waterproof construction between electric motor end cap and the electric machine main shaft.
Background technology
Battery-operated motor cycle or electric bicycle are in use, often running into weather rains or crosses the ponding location, motor is in drench with rain or the sewage dipping among, because of then needing motor is sealed, otherwise, in a single day rainwater enters motor interior, will cause the machine winding coil short circuit, easily causes the abominable accident of car crash when serious.In the prior art, in order to prevent the slit infiltration between electric motor end cap and electric machine main shaft, the bearing, normally between electric motor end cap and electric machine main shaft and bearing, be provided with oil sealing, but because the long-term friction of oil sealing and electric machine main shaft, wearing and tearing easily, cause useful life short,, do not reach the purpose of waterproof if untimely its sealing effectiveness descends greatly.The contact-making surface place glue coated of electric motor end cap and hub for vehicle wheel is to reach the purpose of waterproof.
Summary of the invention
It is close that the purpose of this utility model provides a kind of envelope that is exclusively used between End cover for motor and electric machine main shaft and the bearing, and the waterproof construction of the motor of electric motor car of good sealing effect, long service life.
The utility model comprises motor side cage and electric machine main shaft, and electric machine main shaft passes the hole on the motor side cage, and the other end of motor side cage inner chamber is connected with electric machine main shaft by bearing.Axially be equipped with first rubber seal, porcelain ring, printing ink circle, second rubber seal, lasso in the inner chamber of motor side cage successively.Wherein, the inner surface of the outer round surface of first rubber seal and motor side cage closely cooperates, and the aperture inner surface of second rubber seal closely cooperates and can rotate with main shaft with the outer round surface of electric machine main shaft.Be provided with porcelain ring and printing ink circle between first rubber seal and second rubber seal, described lasso is located between second rubber seal and the bearing.
Because first rubber seal of the present utility model is the surface of internal cavity that closely is fixed on the motor side cage, can prevent effectively that rainwater from infiltrating from electric motor end cap and pedestal slit thereof; Second rubber seal is closely to be fixed on the main shaft of motor, thereby can prevent effectively that rainwater from infiltrating in the motor from the main shaft outer round surface.Because the surface of porcelain ring and the surface smoothness of printing ink circle are good, and ink material has self-lubricating function, add second rubber seal by lasso with the extruding of printing ink circle and porcelain ring, make the rotation contact-making surface between printing ink circle and the porcelain ring tightr, help improving water resistance.Because of between End cover for motor and pedestal and electric machine main shaft and bearing, being provided with the multi-sealed waterproof construction in three places, can reach very good sealed waterproof effect, and long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the local enlarged diagram in the utility model A place.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing makes the utility model and further describing:
The utility model comprises motor side cage 6 and electric machine main shaft 7, and motor side cage 6 is connected to one with end cap 8.Electric machine main shaft 7 passes the hole on the motor side cage 6, and the other end of motor side cage inner chamber is connected with electric machine main shaft 7 by bearing 9.Axially be equipped with first rubber seal 1, porcelain ring 2, printing ink circle 3, second rubber seal 4, lasso 5 in the inner chamber of motor side cage 6 successively.Wherein, the inner surface of the outer round surface of first rubber seal 1 and motor side cage 6 closely cooperates, and makes it the inner chamber that first rubber seal 1 is fixed on motor side cage 6 and does not rotate with electric machine main shaft.The aperture inner surface of second rubber seal 4 closely cooperates and can rotate with main shaft with the outer round surface of electric machine main shaft 7.Be provided with porcelain ring 2 and printing ink circle 3 between first rubber seal 1 and second rubber seal 4, the described porcelain ring 2 and first rubber seal 1 are fixed together, and the described printing ink circle 3 and second rubber seal 4 are fixed together; Described lasso 5 is between second rubber seal 4 and bearing 9.By lasso 5, second rubber seal 4 printing ink circle 3 and porcelain ring 2 are pressed together, make the rotation contact-making surface between printing ink circle and the porcelain ring tightr, help improving the water resistance of contact-making surface.Though the porcelain ring (2) that can be fixed on first rubber seal rotatablely moves with respect to existing between the printing ink circle (3) that can be fixed on first rubber seal, but because the surface smoothness of the surface of porcelain ring and printing ink circle is good, and ink material has self-lubricating function, coefficient of friction is little, thereby can effectively prolong the useful life of two contact friction parts.
Claims (2)
1. the waterproof construction of a motor of electric motor car, comprise motor side cage (6) and electric machine main shaft (7), electric machine main shaft passes the hole on the motor side cage, the other end of motor side cage inner chamber is connected with electric machine main shaft by bearing, it is characterized in that: axially be equipped with first rubber seal (1) in the inner chamber of motor side cage (6) successively, porcelain ring (2), printing ink circle (3), second rubber seal (4), lasso (5), wherein, the inner surface of the outer round surface of first rubber seal (1) and motor side cage (6) closely cooperates, the aperture inner surface of second rubber seal (4) closely cooperates and can rotate with electric machine main shaft with the outer round surface of electric machine main shaft (7), be provided with porcelain ring (2) and printing ink circle (3) between first rubber seal (1) and second rubber seal (4), described lasso (5) is located between second rubber seal (4) and the bearing (9).
