Abstract
The utility model discloses an end cover of an electric furnace transmission case. The end cover comprises a bottom plate, the centre of the bottom plate is provided with a mounting hole which is a stepped hole, a bearing is mounted in the mounting hole, and an inner sealing ring and an outer sealing ring are respectively arranged at two sides of the bearing in the mounting hole. The end cover has a simple structure, a roller bearing is mounted in the mounting hole of the bottom plate, and a sealing gasket is respectively arranged at the inner side and the outer side of the roller bearing in the mounting hole; therefore, the sealing performance of the end cover is improved, and the service life of the electric furnace transmission case is prolonged.
Description
Technical field
The utility model relates to field of electric fires, relates in particular to a kind of electric furnace gearbox cover.
Background technique
Middle frequency furnace is a kind of power supply unit that power frequency 50HZ Ac is changed into intermediate frequency (300HZ is above to 10000HZ); The three-phase main-frequency Ac, become direct current after the rectification, become adjustable electric current of intermediate frequency to direct current again; Supply is by the intermediate frequency alternating current that flows through in electric capacity and the inductor coil; In induction coil, produce the highdensity magnetic line of force, and the metallic material that holds in the cutting induction coil, very big eddy current in metallic material, produced.This eddy current has some character of electric current of intermediate frequency equally, that is, the free electron of metal self will produce heat having in the metal body of resistance to flow.It is made up of several parts such as converter plant, body of heater, stokehold controls.Equipment is widely used in every field such as forging, casting, heat treatment, mechanical hot processing, powder metallurgy.
The gearbox cover sealability of original electric furnace is relatively poor, causes the persistency of production process, has reduced manufacturing efficiency.
The model utility content
In order to remedy the deficiency of existing technology, the purpose of the utility model provides a kind of electric furnace gearbox cover, has effectively solved the relatively poor defective of gearbox sealability.
The technological scheme of the utility model is following:
The electric furnace gearbox cover comprises base plate, it is characterized in that: the base plate center has mounting hole, and mounting hole is a shoulder hole, and bearing is installed in the mounting hole, is positioned at the bearing both sides in the mounting hole and is respectively equipped with the inner and outer sealing circle.
Described electric furnace gearbox cover is characterized in that: described base plate is evenly distributed with several fixed holes along the ring edges.
Described electric furnace gearbox cover is characterized in that: described bearing adopts ball bearing.
The utility model has the advantages that:
The utility model is simple in structure, in the mounting hole of base plate, ball bearing is installed, and the outside that is positioned at ball bearing in the mounting hole is respectively equipped with sealing gasket, has improved the sealability of end cap, has prolonged the working life of electric furnace gearbox.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The electric furnace gearbox cover comprises base plate 1, and base plate 1 center has mounting hole 2; Mounting hole 2 is a shoulder hole; Bearing 3 is installed in the mounting hole 2, and bearing 3 adopts ball bearing, is positioned at bearing 3 both sides in the mounting hole 2 and is respectively equipped with inside and outside seal ring 4,5; Effectively raise the sealability of end cap, base plate 1 is evenly distributed with several fixed holes 6 along the ring edges.
