Hybrid axial bearing

Abstract

The invention provides a hybrid axial bearing. The hybrid axial bearing comprises a first axial iron core, a second axial iron core, a first framework, a second framework and magnetic steel; the second axial iron core is sleeved with the first axial iron core; the first framework is arranged in the position of the axial gap between the first axial iron core and the second axial iron core; the second framework is arranged on one side, far away from the first framework, of the second axial iron core; the magnetic steel is arranged in the position of the radial gap between the first axial iron core and the second axial iron core; the second framework is fixed to the first axial iron core or the second axial iron core through injection molding; and / or the magnetic steel is fixed inside the radial gap between the first axial iron core and the second axial iron core through injection molding. According to the hybrid axial bearing, a coil framework can be prevented from falling, or the numberof parts of the hybrid bearing can be reduced, and the machining cost of the hybrid bearing can be reduced.

Description

technical field [0001] The invention belongs to the technical field of bearings, and in particular relates to a hybrid axial bearing. Background technique [0002] The hybrid axial bearing is a kind of axial bearing in which the magnetic levitation rotor can be stably suspended in the center position during operation through the joint action of electromagnetic force and permanent magnetic force. [0003] The original technical scheme of the hybrid axial bearing is as follows: figure 1 and figure 2 As shown, including screw 1'; rear axial core 2'; positioning ring 3'; coil 4'; coil bobbin 5'; axial core 6'; coil bobbin 7'; coil 8'; magnetic steel 9' ;The magnetic steel fixing frame 10', when assembling, the winding frame 5' and the coil frame 7' are coated with glue on the pins, and then connected together through the pins, and then the axial iron core 6' is passed through the screw 1 ' is locked with the rear axial iron core 2' to prevent the axial iron core 6' from movi...

AI Technical Summary

Problems solved by technology

[0004] The hybrid axial bearing is used on a high-speed motor. When the motor is in a harsh working environment such as shock and vibration, the coil skeleton 7' ​​of the hybrid axial bearing may fall off. The fallen skeleton may rub against the rotor, causing the motor to fail. normal work
