Abstract
The utility model discloses a permanent magnetic rotary drum axle shaft with a bearing conveniently replaced. The permanent magnetic rotary drum axle shaft with the bearing conveniently replaced comprises a shaft body driven by a drive device, a connection plate which is connected with an end cover of a drum body, a bearing press cover and a bearing embedded in the bearing press cover. A press cover which can limit the bearing in the bearing press cover is arranged on the inner side of the bearing press cover. With the structure, when the bearing of an axle shaft end is detached, as the press cover limits the bearing in the bearing press cover, the bearing is taken out along when the axle shaft is separated from the end cover of the drum body and seal performance of the permanent magnetic is not damaged in the end. Problems caused by damage to seal performance of the drum body are basically eradicated. Meanwhile, time spent in bearing maintenance and bearing replacement is saved, on-spot operation is convenient and working efficiency is improved.
Description
One, technical field
The utility model belongs to magnetic separator part technical field, is specifically related to a kind of permanent magnetic pulley semiaxis that is convenient for changing bearing.
Two, background technique
Permanent magnetic pulley is a kind of iron ore beneficiation equipment, and working principle is the principle of utilizing magnetic ore to be attracted by permanent magnet, in the cylinder surface design of material flow warp, form the semicircle magnetic system of a higher magnetic field.When material flow during through this sheet field region, the ferromagnetism ore is caught by powerful magnetic force at once, is adsorbed on the adsorption plane of cylinder.When the ferromagnetism ore be brought to the bottom without magnetic area the time, under Gravitative Loads, drop to the concentrate mouth and discharge.And nonmagnetic assorted stone is discharged from the mine tailing mouth freely by the magnetic separation district.Permanent magnetic pulley is made of the end cap of cylindrical shell, both sides and the axis in the cylindrical shell and magnetic system.One end of axis passes after being positioned at the end cap outside, being used for supporting the bearing of cylindrical shell from end cap and is connected to axle bed; The other end is connected on the bearing that is inlaid in the axle bearing gland cylindrical shell is formed support.When this kind structure need be dismantled half axle end bearing owing to reasons such as maintenance and replacings, need to open the cylindrical shell end cap of semiaxis offside, take out magnetic system, could take out half axle end bearing.Open the seal that end cap has destroyed the permanent magnetic pulley cylindrical shell, magnetic material enters permanent magnetic pulley inside easily, is adsorbed onto magnetic and fastens, and cleaning is got up very difficult, and whole operating process is very loaded down with trivial details, wastes time and energy, and labor intensity is large.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is reasonable in design, need not to open the cylindrical shell end cap and just can conveniently take out half axle end bearing, fundamentally avoided the permanent magnetic pulley semiaxis that is convenient for changing bearing of the destroyed problems of bringing of cylindrical shell seal.
To achieve these goals, the technical solution adopted in the utility model is: this semiaxis comprises axis body, the connecting plate, the bearing gland that are connected with the cylindrical shell end cap that is driven by drive unit and is inlaid in bearing in the bearing gland that be characterized in: the bearing gland inboard is provided with can be with the spacing gland in bearing gland of bearing.
Adopt said structure, when dismantling half axle end bearing, because gland is spacing in bearing gland with bearing, when like this semiaxis being separated with the cylindrical shell end cap, bearing will be taken out of, all the time can not destroy the seal of permanent magnetic pulley cylindrical shell, fundamentally stop the destroyed problems of bringing of cylindrical shell seal.Simultaneously, also save the operating time of safeguarding and change bearing, made execute-in-place easier, improved working efficiency.
Four, description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the I district enlarged view of Fig. 1.
Five, embodiment
As shown in the figure, the utility model comprises by the connecting plate 12, the bearing gland 10 that are connected with cylindrical shell 5 end caps 3 with the axis body 1 that is connected with speed reducer 13, by bolt 2 and is inlaid in the bearing gland 10 and is sleeved on the bearing 4 in axis 11 outsides.Bearing gland 10 inboards are provided with can be with bearing 4 spacing glands 7 in bearing gland 10.This gland 7 is fixed on the bearing gland 10 by screw 8.For the utility model dismounting is more prone to, be provided with six jackscrews 9 in connecting plate 12 outsides, the utility model can be ejected from end cap by this jackscrew 9.Among the figure 6 is for being fixed on the magnetic system in cylindrical shell 5 inner chambers.The utility model semiaxis all adopts cast steel material to make.
Claims (2)
