Embodiment Construction

[0018] The present invention will now be further described in conjunction with examples. As shown in the figure, the insulating layer 7 of the weft-free belt is provided between the outer circumferential surface wall surface of the motor bearing housing 1 and the motor end cover 6, and the epoxy sleeve 2 is sleeved on the inner position of each mounting hole 4 on the bearing housing 1. On the mounting bolts 5, epoxy plate pads 3 sleeved on the bolts 5 are respectively provided on the surfaces of the bearing seats located at the two ends of each mounting hole 4.

[0019] The specific insulation manufacturing method is as follows: evenly wind a layer of weftless tape with a thickness greater than 5mm on the outer circumferential surface of the bearing housing 1, and then dipping and drying the bearing seat with the weftless tape; After tying the insulating material, the bearing seat that has been dipped and dried is subjected to gold processing and shaping, and the insulating materi...

Abstract

The invention discloses an insulating bearing device with good insulating performance, firmness and reliability, simple process and low cost and an insulating method thereof. In the bearing device, an insulating layer is arranged between the bearing seat and the installation supporting device. Its manufacturing method is to wrap the latitude-free tape on the surface of the outer circumference of the bearing seat, then dip paint and dry it, and then carry out gold processing, and set epoxy plate pads and Epoxy bushing, and finally assemble the bearing seat and supporting device into one, and then carry out dipping and drying treatment.

Description

Technical field: [0001] The invention relates to a bearing device and an insulation method thereof, in particular to a motor insulated bearing device and a method for insulating the contact surface between the device and a supporting device. Background technique: [0002] In modern frequency conversion speed control technology, the use of voltage-type frequency converters is prone to shaft voltage and bearing voltage, which will cause shaft current and damage the electric bearing. If the bearing on one side of the motor is insulated, the shaft current loop can be cut off to achieve the purpose of protecting the bearing. The existing bearing insulation method generally uses plasma spraying technology to provide an insulation layer on the inner or outer circumferential surface of the bearing, but the process used in this method is relatively complicated, high cost, difficult to promote, and the sprayed insulation The layer is easily destroyed. Summary of the invention: [0003] Th...
