The motor is an electromagnetic device for realizing electric energy conversion or transmission according to an electromagnetic induction law; at present, the motor is installed in a vehicle using process, an oil pipe in a vehicle system runs from the outer side of the motor, the distance is long, the oil moving distance is increased, a large number of hard oil pipes are used, and the production cost is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a reduction in production cost's an explosion-proof machine.

The technical scheme of the utility model as follows:

an explosion-proof motor is characterized by comprising a base, a stator and a rotor; a rotating shaft is arranged in the center of the rotor, and end covers are arranged at two ends of the machine base; a cast aluminum rotor and a stator are sequentially sleeved outside the rotating shaft; the rotating shaft is a hollow rotating shaft; the joint of the end cover and the rotating shaft is provided with a bearing chamber, and a bearing is sleeved on the rotating shaft in the bearing chamber; a bearing cover is sleeved on the end cover outside the bearing; bearing cap all is equipped with the mounting groove, and the cover is equipped with the sealing washer in the pivot in the mounting groove.

And the winding copper wire on the stator is attached with a carbon nano tube.

The sealing ring is U-shaped in cross section, and one end of the sealing ring is propped against the side wall of the mounting groove, and the other end of the sealing ring is propped against the rotating shaft.

The center of the contact section of the sealing ring in contact with the rotating shaft is bent towards the rotating shaft to form a bending groove, and a sealing collar is sleeved in the bending groove of the cover.

The utility model has the advantages that: because the hollow rotating shaft is adopted, the oil pipe passes through the inside of the rotating shaft, and the oil passing speed is greatly increased; the hollow structure is adopted, and the weight is light; the connecting oil way can directly penetrate through the hollow part instead of bypassing the motor, so that the consumption of hard oil pipes is saved; the cost is reduced for the whole using system.

Drawings

The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.

Wherein: FIG. 1 is a schematic view of the present invention;

FIG. 2 is a schematic view of the structure of the filtering chamber of the present invention;

in the drawing, 1 is a machine base, 2 is a rotating shaft, 3 is a stator, 4 is a cast aluminum rotor, 6 is an end cover, 7 is a winding, 8 is a bearing chamber, 9 is a bearing, 10 is a bearing cover, and 11 is a sealing ring.

Detailed Description

Referring to fig. 1-2, an explosion-proof motor is characterized by comprising a base 1, a rotating shaft 2, a stator 3 and a cast aluminum rotor 4; a rotating shaft is arranged in the center of the machine base, and end covers 6 are arranged at two ends of the machine base; a cast aluminum rotor and a stator are sequentially sleeved outside the rotating shaft; the rotating shaft is a hollow rotating shaft. Because the hollow rotating shaft is adopted, the oil pipe passes through the inside of the rotating shaft, and the oil passing speed is greatly increased; the hollow structure is adopted, and the weight is light; the connecting oil way can directly pass through the hollow part instead of bypassing the motor, so that the consumption of hard oil pipes is saved.

And a carbon nano tube is attached to a copper wire of a winding 7 on the stator. A carbon nanotube material, similar to graphene, is attached to the copper material. The conductivity of the copper-based alloy is 10 times that of copper, the current capacity of the copper-based alloy is 100 times that of the copper, the heat conduction efficiency of the copper-based alloy is 10 times that of the copper, the strength of the copper-based alloy is 300 times that of the copper, and the weight of the copper-based alloy is 1/4-1/6. The motor adopting the material design has the advantages that the direct reduction of copper consumption can be brought by the substantial reduction of the resistance, the motor can benefit both in the low-speed large-torque working condition and the high-speed weak-magnetic working condition, and the efficiency is comprehensively improved. The improvement of current capacity and heat conductivity can improve the selection upper limit of electric density and heat load, and bring the volume reduction of the stator and the improvement of torque and power density. The strength is improved, and great process convenience is brought to automatic winding.

The joints of the end covers and the rotating shaft are provided with bearing chambers 8, and the rotating shaft in the bearing chambers is sleeved with bearings 9; and a bearing cover 10 is sleeved on the end cover outside the bearing. The bearing is placed through the bearing chamber, so that the bearing is conveniently clamped into the bearing on the one hand, and the bearing can be limited by matching with the end cover on the other hand.

Bearing cap all is equipped with the mounting groove, and the cover is equipped with the sealing washer in the pivot in the mounting groove. Through setting up the sealing washer to reinforcing sealed effect.

The section of the sealing ring 11 is U-shaped, one end of the sealing ring props against the side wall of the mounting groove, and the other end of the sealing ring props against the rotating shaft. Sealing washer one end supports the mounting groove lateral wall, and the other end supports the pivot, and is sealed effectual like this, and the sealing washer cross-section adopts the U-shaped structure moreover for the effect that both sides supported is better.

The center of the contact section of the sealing ring contacted with the rotating shaft is bent towards the rotating shaft direction to form a bending groove. Because the center of the contact section is bent to form a triangular structure, the contact section can firmly support the rotating shaft, so that the sealing effect is better; and the sealing clamping ring is matched for use, so that the bending groove part can clamp the rotating shaft more firmly.

And sealing plugs are arranged at two ends of the hollow rotating shaft, and a plurality of through holes are formed in the sealing plugs. Through arranging the sealing plug, perforations (the number of the perforations and the size of each perforation can be designed according to actual needs) can be arranged on the sealing plug so as to facilitate the oil pipe to pass through; and can make inside obtain better dustproof and waterproof effect, prolong the life of parts such as cable.

The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
