Single-surface transmission oil-cooling permanent-magnet speed regulator

Abstract

The invention discloses a single-surface transmission oil-cooling permanent-magnet speed regulator. The single-surface transmission oil-cooling permanent-magnet speed regulator comprises a box body, wherein an input bearing seat part and an output shaft bearing part are arranged on the box body and respectively penetrate through two installation plates, the two installation plates are oppositely arranged at the box body, a conductor rotor part is arranged on the input bearing seat part and comprises a conductor disc, an oil inlet groove is formed in a surface of the conductor disc, a permanent-magnet rotor part is arranged on the output bearing seat part and comprises an intermediate disc, a permanent-magnet disc is arranged on a surface of the intermediate disc by a torsion transfer pin,the permanent-magnet disc is arranged on an air gap adjustment device, an air gap is reserved between the conductor disc and the permanent-magnet disc, and the gap between the conductor disc and the permanent-magnet disc is adjusted by the air gap adjustment device. The single-surface transmission oil-cooling permanent-magnet speed regulator is designed in a single-surface transmission way and issimple in structure, and the conductor rotor part and the permanent-magnet rotor part are short in axial cantilever length, high in assembly accuracy and small in vibration during high-speed rotationand are stable to rotate and can be used for adjusting a speed of a high-speed load.

Description

technical field [0001] The invention belongs to the field of permanent magnet governors, and in particular relates to a single-side transmission oil-cooled permanent magnet governor. Background technique [0002] In large-scale mining, petrochemical, electric power and metallurgy industries, due to the need for energy saving and environmental protection, permanent magnet speed control devices are more and more widely used. The permanent magnet speed control device can adapt to various harsh environments, including places with large grid voltage fluctuations, serious harmonics, flammable, explosive, humid, dusty, etc., and can adjust the speed of the load online to meet the actual operation needs of the system and realize speed regulation Energy saving, speed regulation range 0-98%, energy saving rate 10%-65%. When working, the motor drives the conductor rotor of the permanent magnet governor to rotate, and the copper conductor on the conductor rotor cuts the magnetic induct...

AI Technical Summary

Problems solved by technology

[0003] The existing oil-cooled permanent magnet speed governor uses two conductor disks and two permanent disks, and double-sided transmission. The cantilever of this structure is relatively long (generally 700-1000mm), and the installation accuracy is difficult to guarantee, resulting in high-speed operation. The vibration exceeds the standard. These problems cause the permanent magnet governor to be unable to be used at 3000 rpm and above, which is not conducive to the promotion and application of the product.
