Description
Technical field
This utility model is related to a kind of machine components technical field, specially a kind of generator amature backwater bearing.
Background technology
Electromotor is requisite equipment in commercial production, and in order to improve the efficiency of electromotor, most of producer selects
Using double water innercooling electric generator group, double-water internal cooling unit cooling water is entered from exciter shaft centre bore, by several insulating water inlet pipes
The cooling of generator amature bar is introduced, generator amature backwater bearing is finally come together in, then electromotor is back to by water return pipeline
Inner cold water case, at present, although water seal baffle plate is equipped with two seals ring and wear-resisting close to some generator amature backwater bearings in front and back
Envelope Pericarpium Musae, but, as the baffle plate of water directly contact rotor backwater bearing, hydraulic impact are excessive, occur after longtime running
Leak, the phenomenon of water dumping, cause air to leak into backwater bearing in a large number, cause inner cooling water quality to deteriorate, and affect work efficiency.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of alleviation hydraulic impact, can be prevented effectively from leak, get rid of
The generator amature backwater bearing of water phenomenon.
To solve the above problems, a kind of generator amature backwater bearing described in the utility model, including baffle plate, sealing
Ring, pressing plate and fastening bolt, the baffle plate side are provided with silk screen, and its opposite side is fixedly connected with described by the fastening bolt
Pressing plate；The baffle plate bottom is provided between the sealing ring, and the baffle plate and the pressing plate and is provided with rubber seal；The pressure
Packing ring is provided between plate and the fastening bolt.
The sealing ring is arranged with the baffle plate and the rubber seal gapless.
The rubber seal is arranged with the baffle plate and the pressing plate gapless.
The silk screen is made up of the material with adsorption function.
This utility model has advantages below compared with prior art：
The silk screen arranged on this utility model baffle plate, as which has adsorption function, can effectively alleviate the impulsive force of water, energy
Inner cold water quality is optimized, the negative pressure of sealing ring and rubber seal is reduced, it is to avoid situation of the backwater bearing in longtime running
The lower phenomenon that leak, water dumping are caused because of the impulsive force problem of water, so as to improve work efficiency.
Description of the drawings
Fig. 1 is this utility model structural representation.
In figure：1st, baffle plate, 2, silk screen, 3, sealing ring, 4, rubber seal, 5, pressing plate, 6, fastening bolt, 7, packing ring.
Specific embodiment
A kind of generator amature backwater bearing shown in 1, including baffle plate 1 with reference to the accompanying drawings, sealing ring 3, pressing plate 5 and fastening spiral shell
Bolt 6,1 side of baffle plate are provided with silk screen 2, and its opposite side is fixedly connected with pressing plate 5 by fastening bolt 6；1 bottom of baffle plate is provided with sealing
Rubber seal 4 is provided between ring 3, and the baffle plate 1 and pressing plate 5；Packing ring 7 is provided between pressing plate 5 and fastening bolt 6；Sealing
Ring 3 is arranged with baffle plate 1 and 4 gapless of rubber seal, and rubber seal 4 is arranged with baffle plate 1 and 5 gapless of pressing plate.
When the inner cold water with pressure is sprayed into bearing by rotor apopore, most of kinetic energy of water is inhaled by silk screen 2
It is attached and cannot the reciprocal splash in the bearing, the water adsorbed by silk screen 2 flowed down along baffle plate 1, and now sealing ring 3 is held together and pushed against by pressure
Inner cold water is sealed on baffle plate 1, with contact operation of the rubber seal 4 with rotor, pressing plate 5 is then to rubber seal
4 play fixation, prevent rubber seal 4 from vibration or displacement occurring, and packing ring 7 can effectively decompose fastening bolt 6 to pressing plate 5
Pressure, thus, it is possible to be prevented effectively from backwater bearing leak, water dumping phenomenon, so as to improve work efficiency.
