Description
Technical Field
The utility model relates to a propeller technical field especially relates to a cover is drawn to bearing inner race for stoker end.
Background
A deep groove ball bearing is installed and used in an inner hole (blind hole structure) at the small end of a propeller of the centrifugal machine, and the situation that the deep groove ball bearing is damaged due to overload operation of the deep groove ball bearing or entry of sealing failure foreign matters occurs in the field use process. The condition that the inner ring and the outer ring of the deep groove ball bearing are separated exists in the bearing damage, and at the moment, the bearing outer ring in the small-end bearing hole of the propeller does not have a disassembly fixing point, so that the bearing outer ring is difficult to disassemble and cannot be replaced by a new bearing. When in field maintenance, the bearing is disassembled by welding the disassembling rod on the outer ring of the bearing, and the situation of deformation of the bearing position of the inner hole of the small end of the propeller after the inner ring of the bearing is disassembled due to welding thermal deformation and welding slag splashing often occurs.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art, and providing a bearing outer ring drawing sleeve for a pusher end.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a cover is drawn to bearing inner race for pusher end, includes the propeller, the bearing blind hole has been seted up to the one end of propeller, bearing blind hole internally mounted has deep groove ball bearing, the one end that the bearing blind hole is close to the propeller spiral line still is equipped with draws set mounting groove, it draws the cover to draw to be provided with the bearing inner race between set mounting groove inner wall and the deep groove ball bearing, the bearing inner race is drawn the cover and is drawn the screw hole including the tight circle that supports, draw the circle and a plurality of drawing.
Further, the bearing outer ring drawing sleeve is matched with the drawing sleeve mounting groove, so that the bearing outer ring drawing sleeve is mounted in the drawing sleeve mounting groove.
Furthermore, the abutting ring is located on one side close to the deep groove ball bearing, the drawing ring is abutted to the inner wall of the drawing mounting groove, the abutting ring and the drawing ring are integrally machined to form a metal piece, and the overall strength is high.
Further, the diameter of the abutting ring is consistent with that of the outer ring of the deep groove ball bearing, so that the outer ring of the deep groove ball bearing is pulled out when the abutting ring is pulled.
Furthermore, it is a plurality of draw the screw hole and be four, and set up in proper order the equidistance on drawing the surperficial of circle, can be through having the extracting tool of the same size screw thread in drawing screw hole department installation.
The utility model has the advantages that:
compared with the prior art, the utility model discloses a bearing inner race that sets up draws the quick dismantlement that the cover can conveniently realize propeller bearing inner race, and the bearing is changed in the maintenance of being convenient for, reduces cost of maintenance.

Detailed Description
As shown in fig. 1-2, relate to a cover is drawn to bearing inner race for pusher end, including propeller 3, the bearing blind hole has been seted up to the one end of propeller 3, and bearing blind hole internally mounted has deep groove ball bearing 1, and the one end that the bearing blind hole is close to 3 spirals of propeller still is equipped with draws a set mounting groove, draws to be provided with the bearing inner race between set mounting groove inner wall and the deep groove ball bearing 1 and draws set 2, and the bearing inner race is drawn set 2 and is included to support tight circle 201, draw circle 202 and a plurality of screw hole 203 of drawing.
The bearing outer ring drawing sleeve 2 is matched with the drawing sleeve mounting groove, so that the bearing outer ring drawing sleeve 2 is installed inside the drawing sleeve mounting groove, the abutting ring 201 is located on one side close to the deep groove ball bearing 1, the drawing ring 202 is abutted to the inner wall of the drawing mounting groove, the abutting ring 201 and the metal piece formed by the drawing ring 202 through integrated machining, the diameter of the abutting ring 201 is consistent with the diameter of the outer ring of the deep groove ball bearing 1, so that the outer ring of the deep groove ball bearing 1 can be also pulled out in the lump when the abutting ring 201 is pulled, the number of drawing threaded holes 203 is four, the drawing ring 202 is sequentially arranged on the surface at equal intervals, and a dismounting tool with threads of the same size can be installed at the drawing threaded hole 203.
As shown in figure 3, when in use, the bearing outer ring drawing sleeve 2 is arranged in the drawing sleeve mounting groove before the deep groove ball bearing 1 is arranged in advance, then the deep groove ball bearing 1 is arranged in the bearing blind hole, when the deep groove ball bearing damages the inner ring and the outer ring, as shown in figure 3, 4 drawing threaded holes on the bearing outer ring drawing sleeve 2 can be completely exposed, a dismounting tool with the same thread size is screwed into the drawing threaded hole of the bearing outer ring drawing sleeve 2 for fixing, and the bearing outer ring drawing sleeve 2 and the damaged deep groove ball bearing outer ring 101 can be pulled out together through the outer edge, so that convenient dismounting is realized.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
