Embodiment 1

[0032] Power transmission in material preparation equipment for high vacuum systems.

[0033] The inner magnetic strip fixing frame 4, the outer magnetic strip fixing frame 5, the outer gland 9, the inner gland 10, the active connection plate 6, and the partition cover 3 are all made of stainless steel.

[0034] Fix the partition cover 3 on the vacuum chamber side wall 17 of the vacuum system with bolts, and the partition cover 3 will pass through the vacuum chamber side wall 17 to protrude from the driven shaft 1 outside the vacuum chamber and the driven half coupling mounted on the driven shaft. The shaft is sealed to form a closed vacuum system, and the embedding depth of the driven magnetic half coupling in the active magnetic half coupling is adjusted. Feed circulating cooling water with a pressure of 0.1 MPa and a flow rate of 0.5 tons / hour into the shield 3, turn on the mechanical pump of the high vacuum system, and when the pressure is less than 40Pa, turn on the diffu...

Abstract

The present invention relates to a vacuum system non-contacting flexible magnetic coupler, including driven magnetic semi-coupler cover-mounted on the driven shaft, driving magnetic semi-coupler cover-connected on the driving shaft and isolation cover, the driven magnetic semi-coupler is embedded in the interior of driving magnetic semi-coupler, and the isolation cover is placed between the driven magnetic semi-coupler and driving magnetic semi-coupler.

Description

technical field [0001] The invention belongs to power transmission equipment, and relates to a flexible magnetic coupling, in particular to a non-contact flexible magnetic coupling suitable for a vacuum system. Background technique [0002] In the process of material preparation, for some materials with special properties, such as materials with extremely poor oxidation resistance or extremely high purity requirements, the preparation environment is required to have an ultra-high vacuum or must be carried out in a special atmosphere. For the power transmission equipment that is often used in the preparation of these special materials, due to the existence of the gap between the transmission shafts, it cannot be completely sealed, which will easily cause the atmosphere to leak out, thus affecting the quality of the manufactured materials. [0003] The magnetic coupling uses the magnetism of high-performance permanent magnet steel to transmit torque, and it is non-contact. The...
