Abstract
The utility model relates to a rainproof electric motor, which is utilized in the open air and belongs to the technical field of electric motor structure. The purpose of this utility model is to lead the water to be smoothly drained and effectively isolated outside a stator cavity of the electric motor, thus avoiding that a motor winding is broken down by damp or water and realizing a rainproof motor that is suitable to be used in the open air. The outdoor rainproof electric motor includes a motor fan 1, a motor stator cavity 8 and is characterized in that the top end of the motor fan 1 is designed to be a closed end face, a connection hole is opened on the closed end face to be communicated with a bolt hole 3 at the end of a motor rotating shaft 2, the motor fan and the motor rotating shaft 2 are fixedly connected by a bolt 5. The utility model realizes the effective isolation of the motor stator cavity from the outside rainwater, avoids that the whole motor is damaged when the motor winding is broken down or short-circuited by damp or water, which considerably improves the service life of the electric motor and reduces the repair rate of the electric motor.
Description
One, technical field
The utility model relates to a kind of open-air rainproof motor of using, and belongs to the electric motor structure technical field.
Two, background technology
At present, be applied to the vertical installation motor of open-air occasion on the market, its fan is an open type, and fan and machine shaft junction do not have rational protective measures, and the electric motor end cap end face is a planar structure, be unfavorable for that water flows out, therefore very easily flow in the sleet sky and water, cause the motor internal water inlet, make motor windings because of rainwater soaks, making moist punctures along fan and rotating shaft junction, the damage motor causes whole motor paralysis.
Three, summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, characteristic according to vertical type motor, redesign improves electric motor fan structure and electric motor fan end end cover structure, water is discharged and effectively isolation smoothly in motor stator chamber external enwergy, thereby avoid motor windings because of making moist and water logging bubble punctures, realize a kind of rainproof motor that is applicable to that open-air occasion is used.
The utility model specific design scheme is:
1, electric motor fan one end is changed into closed, process a screw in the machine shaft end, it is fastening that fan and machine shaft fastening means change screw 5 into by shaft block ring 4, thereby realize machine shaft and the isolation of fan junction with the external world.
2, change the electric motor end cap end face into ramp structure by original planar structure, the water that is beneficial to enter the electric motor end cap end face can be discharged smoothly, thereby prevents that current from advancing in the motor stator chamber.
A kind of open-air rainproof motor of using, comprise electric motor fan 1, motor stator chamber 8, its special character is electric motor fan 1 top is made as closed end face, closed end face has connecting hole and is communicated with the screw 3 that establish machine shaft 2 ends, fixedly connected by the connecting hole of closed end face by screw 5 between electric motor fan 1 and the machine shaft 2, realize connecting of machine shaft 2 and electric motor fan 1;
The centre of described screw 5 and screw 3 is provided with packing ring 6 and carries out sealing and fixing;
The end face of described motor stator chamber 8 top electric motor end caps 7 changes ramp structure into by original planar structure, thereby prevents that water from flowing in the motor stator chamber 8 of bottom.
A kind of open-air rainproof motor of using of the utility model has been realized effective isolation of motor stator chamber and extraneous rainwater, avoids motor windings because of making moist and water logging bubble punctures, short circuit, causes whole motor damage.Therefore, this designs the useful life of having improved motor greatly, has reduced the repair rate of motor, has good technical economic benefit and social benefit.

Five, embodiment
Following with reference to accompanying drawing, provide embodiment of the present utility model, be used for formation of the present utility model is further specified.
The rainproof motor of a kind of open-air usefulness of present embodiment is with reference to figure 1-6, comprise electric motor fan 1, motor stator chamber 8, electric motor fan 1 top is made as closed end face, process a screw 3 in the end of machine shaft 2, closed end face has connecting hole and is communicated with the screw 3 that establish machine shaft 2 ends, fastening means between electric motor fan 1 and the machine shaft 2 changes into screw 5 fastening by original shaft block ring 4, the centre of screw 5 and screw 3 is provided with packing ring 6 and carries out sealing and fixing, by realizing connecting of machine shaft 2 and electric motor fan 1 connecting of screw 5 and screw 3, when rainy, use motor, the electric motor fan 1 of one end sealing has prevented the immersion of rainwater effectively, and this connecting mode has been realized machine shaft 2 and electric motor fan 1 junction and extraneous effective isolation; Electric motor end cap 7 changes ramp structure into by original planar structure; the water that helps entering the motor end face can be discharged smoothly; thereby prevent that water from flowing in the motor stator chamber 8; protection motor windings 9 is because of water inlet is soaked, making moist punctures, and avoided whole the motor problem very easily damaged of rainy day out of doors.
A kind of open-air rainproof motor of using of the utility model has been realized effective isolation of motor stator chamber and extraneous rainwater, avoids motor windings because of making moist and water logging bubble punctures, short circuit, causes whole motor damage.Therefore, this designs the useful life of having improved motor greatly, has reduced the repair rate of motor, has good technical economic benefit and social benefit.
