Abstract
The utility model belongs to a special mechanical pulling tool, and relates to a shredder cutter drum spindle bearing puller applicable to detachment of shredder cutter drum spindle bearings in a KTC80 series. The puller comprises a pulling plate and a lead screw, the pulling plate is a cylindrical body, a thread matching with an external thread of a taper sleeve is machined at a port of a large open end, a thread identical to a lead screw thread in size is machined at a port of a small open end, the port of the small open end is connected with the lead screw, and a nut is machined at the tail end of the lead screw. The puller is simple in structure, convenient to use, timesaving, laborsaving, and capable of completing normal quick detachment of the bearings without damaging assembly accuracy of the bearings, the taper sleeve and a spindle.
Description
Technical field
The utility model belongs to the special-purpose machinery drawing device, can filament cutter big or middle repair or the trouble hunting of cutter drum in the drum of tool setting quickly and easily main shaft bearing dismantle or install, time saving and energy saving, and can not damage bearing, tapered sleeve, be applicable to the dismounting of KTC80 series chopping machine knife drum main shaft bearing.
Background technology
large to filament cutter, in repair or the tool setting tympanic part divides and carries out in trouble hunting, need the tool setting tympanic part to divide main shaft bearing to dismantle rear inspection cleaning and oil injecting lubricating, because cutter drum spindle drive end bearing fixedly mounts on main shaft by withdrawal sleeve (tapered sleeve), this withdrawal sleeve is located with end plate on bearing, must first take out withdrawal sleeve when the dismounting bearing, need sizable power to go to overcome friction between the matching surface of bearing and withdrawal sleeve and withdrawal sleeve and axle, be subjected to installation site and structural limitations, can't use the existing various tools of exchanging work that draw that bearing and tapered sleeve are normally dismantled, can only adopt and knock vibrations and wait the strong destruction mode to dismantle, each dismounting need be taken time longer, and cause bearing, tapered sleeve damages to be scrapped and the spindle mounted precise decreasing.
Former when chopping machine knife drum main shaft bearing is dismantled, the powerful dismounting of the instrument such as can only use hammer, copper rod, spanner, lever up, need cost tapered sleeve and bearing could be taken out in nearly 90 minutes, and the screw thread on tapered sleeve all can be destroyed, causes tapered sleeve damage or scrap, when needing when mounted reparation or changing tapered sleeve, bearing after dismounting descends because of quality of fit, also needs to change, and causes the non-normal consumption of accessory, expend simultaneously a large amount of maintenance time, affected the maintenance progress.
Summary of the invention
The purpose of this utility model is to provide a kind of chopping machine knife drum main shaft bearing drawbench, and it is simple in structure, and is easy to use, time saving and energy saving, does not damage bearing, tapered sleeve and spindle mounted precision.
Realize that the technical scheme that the utility model purpose is taked is: formed by drawing dish and leading screw, the drawing dish is cylindrical body, the port of large openend is processed with the screw thread that is complementary with the tapered sleeve external screw thread, the port of little openend is processed with the measure-alike screw thread of threads of lead screw and is connected with leading screw, and the leading screw end is processed with nut.
Drawing dish axial length is 94～105mm, and the screw thread axial length that is connected with leading screw is 13～17mm, and the screw thread axial length that tapered sleeve connects is 28～32mm, per inch 12 teeth, 55 ° of angle of threads; Leading screw length is 250～280mm, and the screw thread specification is M22 * 2.
Useful technique effect of the present utility model is: due to the principle that adopts the spiral drawing, when dismounting chopping machine knife drum main shaft bearing, the powerful dismounting of the instrument such as need not to use hammer, copper rod, spanner, lever up, as long as the internal thread of large openend is connected with the tapered sleeve external screw thread, come rotational lead screw by the nut handle again, along with screw mandrel rotates, the steel pricker cover in the drawing dribbling and bearing moves outward together, pull out like a cork bearing, average consuming time is 5 minutes.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the screw thread schematic diagram that the utility model drawing dish is connected with tapered sleeve.
In figure: drawing dish 1, screw mandrel 2, screw thread 3.
The specific embodiment
Referring to Fig. 1, this device is comprised of drawing dish 1 and leading screw 2, and drawing dish 1 is cylindrical body, and the port of large openend is processed with the screw thread 3 that is complementary with the tapered sleeve external screw thread, the port of little openend is processed with the screw thread identical with leading screw 2 thread sizes and is connected with leading screw 2, and leading screw 2 ends are processed with nut.Drawing dish 1 axial length is 94～105mm, and the screw thread axial length that is connected with leading screw 2 is 13～17mm, and screw thread 3 axial lengths that tapered sleeve connects are 28～32mm, per inch 12 teeth, 55 ° of angle of threads; The length of leading screw 2 is 250～280mm, and the screw thread specification is M22 * 2.
Use makes drawing dish 1 is screwed on the screw thread of tapered sleeve flange, and then screw mandrel 2 is screwed in the screwed hole of centre of drawing dish until withstand main shaft end face center position, inserts at last the nut handle.Because this bearing size is larger, can put boosting-rod at the handle two ends, twist by boosting-rod and revolve screw mandrel, along with screw mandrel one circle circle rotates, drawing dish 1 is with steel pricker cover and bearing outer moving together, and bearing is drawn out, and completes dismounting, and through measuring and calculating, on average consuming time is 5 minutes.
