The invention relates to a flameproof heavy-duty vibration motor, which belongs to the technology in the field of material conveying equipment. In the present invention, the weighted block is symmetrically installed on the rotating shaft at both ends of the rotor coil, and support bearings are symmetrically installed on both sides of the weighted block. The outer ring is axially positioned by the end cover. The seal is installed in the seal groove of the seal ring plate and set on the rotating shaft between the rotor coil and the support bearing. The lead sleeve is made of flame-retardant elastic rubber material. The hollow cylindrical structure composed of the isolation section and the compression connection section has a number of not less than 3 circumferential convex rings on the inner circle. The temperature measurement point of the temperature measuring element is close to the outer ring of the supporting bearing, and the Thermocouples are embedded in the body close to the stator winding. The invention has the advantages of good explosion-proof sealing performance, low temperature rise of the motor, difficult burning of the coil, safe and reliable use, and the like.
Description
technical field [0001] The invention relates to a flameproof heavy-duty vibration motor, which belongs to the field of material conveying equipment. Background technique [0002] With the increasing scale of production in the domestic mining industry, the requirements for safe production are getting higher and higher, and the application of explosion-proof vibration equipment is becoming more and more extensive. As the vibration source of vibration equipment, explosion-proof vibration motor has the advantages of simple structure, convenient installation and disassembly, etc., so it is more and more widely used in occasions that require explosion-proof requirements. However, as a motor with special purpose and structure, this motor is directly installed on the vibration equipment, and it vibrates together with the vibration equipment when the vibration equipment is working. The following serious problems are exposed: (1) During the working process of the vibration motor, the...
