Abstract

The utility model discloses a heat pipe vibration motor, which is widely used as an excitation source for vibration equipment such as screening, material feeding and transportation in mining, metallurgy, coal, building materials and other industries. It does not change the basic structure of the existing vibration motor, and is characterized in that: the rotor shaft of the vibration motor is a heat pipe shaft, the cold end of the heat pipe shaft has cooling fins, and the cavity of the heat pipe shaft is equipped with a heat-conducting medium. Because it uses heat pipes to transfer the heat generated by the rotor, stator, and bearings during operation to the outside of the motor through the heat pipes, ensuring that the motor works at a constant low temperature, effectively avoiding the burning of the motor and prolonging the life of the motor.

Description

Heat pipe vibrating motor

The utility model relates to a kind of vibrating motor, is widely used in the exciting source of the vibratory equipment such as screening, fragmentation, feed, conveying of industries such as mine, metallurgy, coal, building materials.

Existing vibrating motor is full-closed structure, and its internal temperature is higher, the long-term motor that under higher temperature, moves, and the one, the lubricated bad of bearing causes the bearing dry grinding and burns motor, and the 2nd, the containing of stator line is easily burnt.Therefore the life-span of vibrating motor is shorter.

The purpose of this utility model provides a kind of full-closed structure that does not change existing vibrating motor, and can rapidly the motor internal heat be reached the motor outside, the heat pipe vibrating motor that rotor and bearing are worked under constant temperature.

Task of the present utility model realizes as follows, it comprises that a Daepori leads to vibrating motor, it is characterized in that: the armature spindle of vibrating motor is the heat pipe axle, the cold junction of heat pipe axle has radiating fin, in the cavity of heat pipe axle heat-conducting medium is housed, special-shaped heat pipe heat is arranged in the stator, and the support of bearing is special-shaped heat pipe support, and there is the heat conduction fin in the hot junction of heat pipe axle.

The utlity model has following effect: it does not change the basic structure of existing vibrating motor, adopt heat pipe that the heat that rotor, stator, bearing are produced in operation process is reached the motor outside by heat pipe, the assurance motor is worked under constant low temperature, effectively avoid burning of motor, prolonged the life-span of motor.

Below with reference to accompanying drawing and embodiment, concrete structure of the present utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of heat pipe axle of the present utility model.

The utility model does not change the full-closed structure of existing vibrating motor, but be fastened with a heat pipe axle 4 at the center of rotor 1, be filled with the heat-conducting medium of 1/3rd to 3/4ths cavitys in this cavity, this heat-conducting medium is formulated by water and additive, can effectively prevent the slow chemical reaction of carbon steel and water, improve heat pipe 4 life-spans of axle.

Be with 1～10 radiating fin 5 in heat pipe axle 4 cold junction peripheries, for the big motor of power, also can be at the lower heat conduction fin 3 of the hot junction of heat pipe axle 4 assembling, to strengthen hot junction heat conduction.

In order to make full use of the conductive force of heat pipe, prolong the useful life of motor, can also increase the outer rim of rotor 1, increase the inner edge of stator 2 simultaneously, under the constant prerequisite of power of motor and efficient, change its electromagnetic load and distribute, thereby rotor 1 heat production is increased, and derive outside the motor by heat pipe axle 4.

In the use, vibrating motor is installed should 15～90 ° inclination angle, and cold junction upwards is exposed on the outside, and normal condition heat pipe axle 4 also tilts, heat-conducting medium is in the hot junction of heat pipe axle 4, medium is in saturation condition in the pipe, and when vibrating motor was worked, medium heat absorption evaporation rose to cold junction, by cold junction fin 5 heat is distributed to the external world, steam is after cold junction is condensed into the globule, because the effect and the oscillating action of gravity are back to the hot junction along wall, participates in circulation next time again.Therefore, it can make the heat production of rotor 1, the heat production of stator 2, and the heat production of bearing absorbs rapidly and reaches cold junction to extraneous.The assurance vibrating motor is worked under constant low temperature, has avoided the phenomenon of burning of motor, has prolonged the life-span of motor.

In order to prolong the useful life of motor to greatest extent, make full use of this high-performance heat transfer components of heat pipe, also can in the stator 2 line bags of vibrating motor, a plurality of special-shaped heat pipes be set, become heat pipe heat, same, also the support of bearing can be made special-shaped heat pipe support.
