Energy-saving electric roller

Abstract

The invention discloses an energy-saving electric roller, which belongs to the technical field of industrial production and material handling, and comprises a roller body, a permanent magnet synchronous motor and a speed reducer, openings are formed in the two ends of the barrel, and fans are installed at the openings and can dissipate heat for the permanent magnet synchronous motor. During assembly, after the motor and the speed reducer are assembled externally, the motor and the speed reducer are plugged into the drum body, after the speed reducer and the drum body are fixedly connected through pins, the first fan and the second fan are installed at the openings in the two ends of the drum body respectively, and then assembly operation of the energy-saving electric drum is completed. Lubricating oil does not need to be injected into the energy-saving electric roller to dissipate heat of the roller, so that the defect of oil leakage is overcome, and meanwhile, due to the adoption of the permanent magnet synchronous motor technology, the purpose of saving energy can be achieved. Meanwhile, the fans are installed at the two ends of the barrel, heat in the barrel can be dissipated in time, and damage to equipment such as a motor in the barrel due to overheating is avoided.

Description

technical field [0001] The invention belongs to the technical field of industrial production and material handling, and in particular relates to an energy-saving electric drum. Background technique [0002] With the development of the economy and the progress of society, energy conservation and emission reduction has become the consensus of the whole people and has been paid more and more attention. Electric drum is an indispensable industrial product in industrial production and has a wide range of applications in industrial production. [0003] In the traditional oil-immersed electric drum, the motor and the reducer are built into the drum. The inside of the drum is filled with lubricating oil and sealed with sealing rings on both sides, which is equivalent to the application of the drum as a reducer. The lubricating oil injected into the oil-immersed electric drum will bring greater resistance to the rotation of the motor and reducer, thus greatly increasing energy consu...

AI Technical Summary

Problems solved by technology

The lubricating oil injected into the oil-immersed electric drum will bring greater resistance to the rotation of the motor and reducer, thus greatly increasing energy consumption

[0004] At the same time, the lubricating oil in the drum needs to be replaced regularly. With the long-term rotation of the drum, the tight seal will cause the drum to not dissipate heat in time. The sealing ring will inevitably experience rubber ring aging, and the electric drum will leak oil. For industrial production is a danger that cannot be ignored

In addition, because the traditional drum is sealed with a sealing ring, it will inevitably overheat due to the shape and working conditions, which will cause the motor to be prone to demagnetization. The demagnetization of the motor will cause the internal rotor and stator of the motor to overheat, and over-speed rotation, etc., thus damage the device
