Abstract
The utility model discloses an insulation structure for a motor rotating shaft bearing and a housing end cap. A bearing sleeve (2) is sleeved on a bearing (1), part of the outer circumferential surface of the bearing sleeve (2) extends outwards to form a circle of flange, the end surface of an end cover (3) and the end surface of the flange of the bearing sleeve (2) are fitted with each other and fixed through a bolt (5), an insulating material (7) is arranged between the end surface of the end cover (3) and the end surface of the flange of the bearing sleeve (2), the part of the bolt (5) in the end cover (3) is sleeved with an insulated sleeve (4), and a rubber washer (6) is sleeved between the head part of the bolt (5) and the end cover (3). According to the utility model, a glass cloth board at the contact part between the bearing sleeve and the end surface serves as the main insulating material, and an external hot jacket steel ring and the bearing sleeve are integrated, so that the disassembly is convenient, and reusability is realized. The insulation structure is mainly used for disconnecting an electric loop between a motor rotating shaft and a baseframe, thereby preventing electric corrosion.
Description
Technical field
The utility model relates to machine field, relates in particular to the insulation system of a kind of machine shaft bearing and housing end plug.
Background technology
Big motor, machine shaft and support chien shih require to realize insulation, and main effect is that the electric loop between machine shaft and support is broken off, and guarantee electric current not through bearing, and the prevention galvanic corrosion produces.Big motor the inside all is to use insulation bearing for realizing above-mentioned purpose.At present, this insulation bearing is domestic also not to manufacture, and is foreign import all, so this insulation bearing price is rather stiff, institute has reduced competitive advantage so that whole motor price is unable to come down.
The utility model content
The utility model technical problem to be solved is to provide a kind of use plain bearing, realizes the insulation system of machine shaft and support insulation.
The technical scheme of the utility model is following: the insulation system of a kind of machine shaft bearing and housing end plug; Comprise bearing (1), bearing holder (housing, cover) (2), end cap (3); Its centre bearer bush (2) is enclosed within on the bearing (1); This bearing holder (housing, cover) (2) outer circumference surface part stretches out and forms a circle flange, and said end cap (3) end face and this bearing holder (housing, cover) (2) flange end face are fitted fixing through bolt (5), and its key is: be provided with insulating material (7) between said end cap (3) end face and this bearing holder (housing, cover) (2) flange end face; The part that said bolt (5) is positioned at end cap (3) is with insulating sleeve (4), is with rubber washer (6) between this bolt (5) head and the end cap (3).Through insulating material bearing holder (housing, cover) (2) and end cap (3) are separated, electric current does not form the loop, has reached the prevention galvanic corrosion equally and has produced.
Above-mentioned insulating material (7) is a glass-cloth board, also is provided with insulating material (7) between said bearing holder (housing, cover) (2) and the steel bushing (8), and this steel bushing (8) is close to bearing holder (housing, cover) (2) flange, and this insulating material (7) is fixing by steel bushing (8).Through steel bushing (8) insulating material is waled with bearing holder (housing, cover) (2) and to be integrally formed.
Be provided with one deck polyester film 6050 between SI semi-insulation material (7) that above-mentioned steel bushing (8) is waled and the steel bushing (8).It is to improve friction that polyester film 6050 is set between insulating material (7) and the steel bushing (8), prevents to skid.
Beneficial effect: the utility model adopts glass-cloth board as main insulating material in bearing holder (housing, cover) and end cap contact site, and outside hot jacket steel ring and bearing holder (housing, cover) form an integral body, and be not only for convenience detach but also can reuse.Main effect is that the electric loop between machine shaft and support is broken off, and the prevention galvanic corrosion produces.
