Compared with prior art, the beneficial effects of the utility model are：The utility model banbury axle end sealing device
The axle sleeve being connected with armature spindle by the setting outside banburying chamber, sets sealing shroud outside axle sleeve, and sealing shroud is by left and right two halves group
Into installation easy to disassemble；In armature spindle rotary course, in the case where the screw thread of axle sleeve and sealing shroud medial surface cooperates, banburying
Material in machine is subject to the axial thrust of screw rod with the axial propulsive thrust of screw thread simultaneously, when between axial thrust and axial propulsive thrust
When reaching balance, material is always positioned at the porch in the gap between axle sleeve, sealing shroud, so as to realize that dust is sealed, sealing effect
It is really good, long service life.
Brief description of the drawings
Fig. 1 is the structural representation of the banbury axle end sealing device of the implementation method of the utility model one.
Wherein, 1- axle sleeves；2- sealing shrouds；3- armature spindles；4- apical rings；5- wear rings；6- thrust rings；21- screw threads；22- enters
Hydraulic fluid port.
Specific embodiment
The utility model is described in detail below with reference to specific embodiment shown in the drawings.But these embodiment party
Formula is not intended to limit the utility model, structure that one of ordinary skill in the art is made according to these implementation methods, method or
Conversion functionally is all contained in protection domain of the present utility model.
In the diagram of the application, for the ease of diagram, structure or some partial sizes can relative to other structures or
Part is exaggerated, therefore, it is only used for the basic structure of the theme of diagram the application.
Refer to accompanying drawing 1, banbury axle end sealing device of the present utility model, including：Axle sleeve 1, the axle sleeve 1 passes through key
Groove is connected with closed-smelting machine rotor axle 3, and the step of the end of the axle sleeve 1 is embedded in the annular groove of the armature spindle 3, the axle sleeve
1 is externally provided with sealing shroud 2, and gap is left between the axle sleeve 1 and the sealing shroud 2, and the sealing shroud 2 is made up of left and right two halves,
The inner side mounting thread 21 of the sealing shroud 2, the screw thread 21 is rectangular thread or trapezoidal thread, the rotation direction of the screw thread 21
It is oppositely oriented with the armature spindle 3；Material is located in the banburying chamber of banbury, is looked down upper end from banburying chamber described in Fig. 1, if
The armature spindle 3 is to turn clockwise, then the corresponding screw thread 21 is left hand thread, if armature spindle is rotate counterclockwise, that
The corresponding screw thread 21 is right-handed thread.
Further, apical ring 4, wear ring 5, thrust ring 6 are sequentially provided with outside the sealing shroud 2.
It should be noted that the sealing shroud 2 is fixed in frame, it is detachably connected with frame, the thrust ring 6 is fixed
On the sealing shroud 2.The one end of the axle sleeve 1 is connected with the armature spindle 3, and the other end is engaged with the wear ring 5, described
Axle sleeve 1 drives the wear ring 5 to rotate.Spring assembly is provided between the axle sleeve 1 and the wear ring 5, is made described wear-resisting
