Abstract
A kind of specific purpose tool for milling train four roll end bearing assemblings, it is characterized in that: this specific purpose tool comprises a metal sleeve, the rear portion undergauge of sleeve also extends to form handle portion, on the front end face of sleeve, offer two layers of shoulder hole, the space orientation hole, outer ring that its China and foreign countries' shoulder hole is bearing, in interior shoulder hole, be equipped with the inner core that the inner ring with bearing offsets, during use, sleeve is nested with on bearing by outer shoulder hole, behind location, by beaing handle portion, the inner ring that inner core apical axis is held packs bearing in retainer into.The utility model adopts the mode of sleeve and inner core combination, simple and reasonable, solve preferably assembling process middle (center) bearing and struck inclined to one side phenomenon, greatly improved bearing service life, eliminated the Fire accident causing because of bearing assembling completely, safe and reliable, not only for milling train four roll end bearing assemblings, also applicable to enterprise of the same type and similar appointed condition.
Description
Technical field
The utility model relates to a kind of assembling tool, is specifically related to a kind of specific purpose tool for milling train four roll end bearing assemblings.
Background technology
The wiper of SENDZIMIR corrosion resistant plate hoop mill adopts two rollers and the combination of four rollers, and frizing is respond well, but the maintenance and management of these wipers is had to very large difficulty, particularly four roller wipers.SENDZIMIR corrosion resistant plate hoop mill four roller wiper end bearings adopt the biserial deep groove ball bearing that model is 4203, and retainer adopts nylon material.
Four roller wiper end bearings and four roller roll necks are interference fit, because its retainer is nylon material, thus after can not adopting bearing heater heating, assemble, in order to avoid there is distortion in retainer.In original loading procedure, for sleeve top inner ring, knock in, exist and strike inclined to one side top to retainer, outer ring phenomenon.
End bearing reaches as high as 6000r/min in milling train operation process, also bear certain axial force, if retainer, outer ring were once subject to overbump, there is tiny cracked, distortion, damaged and slight jam and do not check out and come into operation, when serious, can cause fire.
Through looking into, the existing patent No. is the main thrust bearing assembling tool of the Chinese patent < < booster > > of CN201120436470.4, there is the external screw thread coordinating completely with the internal thread of main shaft right-hand member main thrust bearing assembling screw rod left part, main thrust bearing assembling screw rod right part has trapezoidal thread, the nut of trapezoidal thread fit on trapezoidal internal thread.It is when the assembling of the main thrust bearing of booster, and what change assembling tool is subject to strength mode, solves the easily problem of consume of main thrust bearing dismounting screw rod.But it is for the main thrust bearing assembling of booster use, and be not suitable for the assembling of milling train four roll end bearings.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of simple in structure, easy to use and reliable specific purpose tool for milling train four roll end bearing assemblings is provided for the above-mentioned state of the art, solve original assembling process middle (center) bearing and struck inclined to one side phenomenon, greatly improved bearing service life.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of specific purpose tool for milling train four roll end bearing assemblings, it is characterized in that: comprise a metal sleeve, the rear portion undergauge of sleeve also extends to form handle portion, on the front end face of sleeve, offer two layers of shoulder hole, the space orientation hole, outer ring that its China and foreign countries' shoulder hole is bearing, in the interior shoulder hole of sleeve, be equipped with the inner core that the inner ring with bearing offsets, under use state, sleeve is nested with on bearing by outer shoulder hole, behind location, by beaing handle portion, the inner ring that inner core apical axis is held packs bearing in retainer into.
As improvement, the aperture of described outer shoulder hole and the race diameter of bearing are suitable, and the degree of depth of outer shoulder hole is less than the height of bearing, and the degree of depth of outer shoulder hole is putting into bearing and make it not drop and be as the criterion under flat condition.
As improvement, described inner core is a columnar metallic sheath, and the end face of inner core and the inner ring of bearing match, and inner core is embedded in interior shoulder hole and stretches out the bottom stage face of outer shoulder hole, and the height that inner core stretches out bottom stage face portion is 0.6～1.0cm.
As improvement, the front end face of described sleeve is annular plane, and what handle portion was hollow is cylindrical.
Compared with prior art, the utility model has the advantage of: adopt the mode of sleeve and inner core combination, by sleeve, bearing is positioned, avoid being offset in assembling process, by inner core, bearing is knocked in retainer.The utility model is simple and reasonable, solve preferably assembling process middle (center) bearing and struck inclined to one side phenomenon, greatly improved bearing service life, eliminated the Fire accident causing because of bearing assembling completely, safe and reliable, not only for milling train four roll end bearing assemblings, also applicable to enterprise of the same type and similar appointed condition.
Accompanying drawing explanation
Fig. 1 is the structure cutaway view of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, the specific purpose tool for milling train four roll end bearing assemblings of the present embodiment, comprise a metal sleeve 1, the rear portion undergauge of sleeve 1 also extends to form handle portion 11, front end face at sleeve 1 is annular plane, inside offer two layers of shoulder hole, the space orientation hole, outer ring that its China and foreign countries' shoulder hole 12 is bearing, the outer aperture of shoulder hole 12 and the race diameter of bearing are suitable, for being nested with location bearing, the degree of depth of outer shoulder hole 12 is less than the height of bearing, the degree of depth of outer shoulder hole 12 is putting into bearing and make it not drop and be as the criterion under flat condition, in the interior shoulder hole 13 of sleeve 1, be equipped with the inner core 2 that the inner ring with bearing offsets, inner core 2 is a columnar metallic sheath, the end face of inner core 2 and the inner ring of bearing match, inner core 2 is embedded in interior shoulder hole 13 and stretches out the bottom stage face of outer shoulder hole 12, the height that inner core 2 stretches out bottom stage face portion is 0.6～1.0cm, like this, during use, sleeve 1 is nested with on bearing by outer shoulder hole 12, avoid assembling process middle (center) bearing to occur skew, behind location, by beaing handle portion 11, the inner ring that inner core 2 apical axis are held packs bearing in retainer into, what handle portion 11 was hollow is cylindrical, convenient operation.
Effect after implementing: adopt the specific purpose tool of the present embodiment to assemble SENDZIMIR milling train four roller wiper end bearings, use easy and convenient, prevent that bearing from knocking in process, because the top of assembling tool is inclined to one side, slip causes retainer impaired, solve assembling process middle (center) bearing completely and struck inclined to one side phenomenon, greatly improve bearing service life, eliminated the Fire accident causing because of bearing assembling completely.Effect is fairly obvious.
