Abstract

The invention discloses an engine and motor insulation end cover insulation structure, which comprises a bearing pedestal, a lantern ring, an end cover and an insulation layer, wherein the structural form of one end of the bearing pedestal is a flange, and the flange is provided with an installation hole; the lantern ring is installed on the bearing pedestal and is positioned between the end cover and the bearing pedestal, and the lantern ring is positioned through the end surface of the flange of the bearing pedestal; the end cover is installed on the bearing pedestal and is positioned on the position of the lantern ring; the bearing pedestal is installed on the end cover through a fastener, the fastener is externally coated with an insulation sleeve, and the insulation sleeve is installed in the installation hole; and the installation layer is arranged on the outer surface of the bearing pedestal and is next to the insulation layer. By use of the structure, the lantern ring is additionally arranged between the end cover and the bearing pedestal. Compared with an existing structure, the structure disclosed by the invention is characterized in that the end cover can be prevented from being in direct contact with the insulation layer in an assembling and disassembling process to better prevent the insulation layer from being damaged during assembling so as to greatly reduce an influence on the insulation performance of the insulation layer in the assembling process.

Description

technical field [0001] The invention relates to the technical field of motor insulation equipment, in particular to an insulation structure of a generator and a motor insulation end cover. Background technique [0002] At present, in order to prevent the electric corrosion of the bearing by the shaft current, the end cover is often designed as an insulating end cover. In order to realize the insulation of the end cover, the common design method is to design the end cover into two parts, that is, divide the end cover and bearing housing, then, insulate the junction of these two parts. Specifically: the outer diameter surface of the connection between the bearing seat and the end cover is covered with an insulating layer to achieve the purpose of insulation. [0003] However, just because the insulating layer is located on the mounting surface of the end cover, and its hardness is low, it is very easy to cause damage to the insulating layer during the assembly and disassembly...
