Embodiment Construction

[0015] Such as figure 1 As shown, the insulating bearing chamber of the motor of the present invention is composed of a bearing inner cover 1 and a bearing outer cover 6 connected. The inner surface of the bearing inner cover 1 in contact with the bearing 3 is cast or die-casted with a bearing inner cover insulating layer 2 made of non-conductive material, and the inner surface of the bearing outer cover 6 in contact with the bearing 3 is cast or die-cast with a non-conductive material Made bearing cover insulation layer 5. Usually, the thickness of the insulating layer 2 of the bearing inner cover and the insulating layer 5 of the bearing outer cover is 1-10mm, which can meet the needs of blocking the motor shaft current; in special cases, the insulating layer 2 of the bearing inner cover and the bearing The thickness of the insulating layer 5 of the outer cover. The insulating layer 2 of the bearing inner cover and the insulating layer 5 of the bearing outer cover are made...

Abstract

The invention discloses a motor insulation bearing chamber which is formed through connection of a bearing inner cover and a bearing outer cover. A bearing inner cover insulation layer made from non-conducting material is casted on the surface of the inner side of the bearing inner cover, which is contacted with a bearing, and a bearing outer cover insulation layer made from non-conducting material is casted on the surface of the inner side of the bearing outer cover, which is contacted with a bearing. With the adoption of the motor insulation bearing chamber, the problem that the current of a motor shaft is incompletely cut in the prior art is solved; and meanwhile, the motor insulation bearing chamber is convenient to be applied to a flame-proof type motor because an insulation material does not appear on a flame-proof surface.

Description

technical field [0001] The invention belongs to the technical field of motor equipment, and in particular relates to an insulating bearing chamber for a motor. Background technique [0002] The motor has a large shaft current due to its own structural problems or external power supply problems, and the motor bearing will be damaged quickly due to electric corrosion. Therefore, the existing technology generally uses insulating bearings or insulating end covers to block the motor shaft current. . However, the insulation layer of these two methods is relatively thin, and the effect of blocking the AC component of the motor shaft current is poor, and the bearing life will be shortened; in addition, the application cost of insulating bearings is high, and large-size bearings are difficult to order, and non-metallic materials exist. The aging problem makes it difficult to apply the insulating end cover technology to the flameproof motor. Contents of the invention [0003] The ...
