Abstract
The utility model relates to a mounting and dismounting tool for nonstandard roller bearings, which comprises a radial handle, two tension round bars with round heads on the top and threaded tails, a lead screw ontology, a lead screw and a thrust bearing. The tail of the lead screw is connected with the thrust bearing and contacted with the center of a cross shaft; the two tension round bars with round heads on the top and threaded tails are tightened in any two symmetric threaded holes on the lead screw ontology; the two tension round bars with round heads on the top and threaded tails can adjust position by moving along the rectangular groove equipped on the lead screw ontology; the radial handle is arranged in the round hold at the top of the tension round bar. The utility model fully overcomes the deficiencies of nonstandard roller bearings such as great weight, small activity space for mounting and dismounting, low recovery utilization rate and so on, and can complete the dismounting and recovery work of the nonstandard roller bearings with simplicity and reliability. The utility model is suitable for the dismounting of similar bearings under similar working conditions, in particular to the dismounting of bearings arranged inside the shaft hole.
Description
Technical field
The utility model relates to a kind of extracting tool that is used for the nonstandard roller bearing of rolling machinery final drive shaft universal-joint spindle.
Background technology
Rolling machinery is one of smelter main equipment, the dismounting of the nonstandard roller bearing of its final drive shaft universal-joint spindle ubiquity in the daily operation of procedure for steel rolling in metallurgical industry factory, for example equipment such as heavy and medium plate mill, jobbing sheet-rolling mill and various shape rolling mills are in the application of maintenance or accident maintenance operation.Because this nonstandard roller bearing weight is bigger, structure is complicated, the fit tolerance strictness, especially it is installed between rolling mill final drive shaft universal-joint spindle bearing saddle bore and the cross axle, limited by structure space, general extracting tool can't use, usually people adopt (for example gas cutting chopping of various destructive means during the field stripping operation, electric welding is auxiliary welding equipment etc. on bearing) it is taken out by force, the result not only wastes a large amount of activity durations, even influence the daily production operation time of enterprise, the more important thing is numerous expensive roller bearings can not be recycled, increased a large amount of production costs virtually for enterprise.The author is once at certain iron company's Heavy Plate Plant duration of work, this there is practical impression, calculated an account roughly, if this, maintenance capacity was 12 times in bearing year, (every cover universal-joint spindle comprises 4 nonstandard roller bearings to adopt commonsense method loss bearing 12 * 4=48,2.5 ten thousand yuan of every cover bearing prices), waste activity duration 3 * 12=36 hour (this steel rolling mill's day pure benefit 1,000,000 yuans), then this enterprise to increase cost be ten thousand yuans of 48 * 2.5+36/24 * 100=270, as seen costly, waste is serious.
The utility model content
Big in order to have overcome nonstandard roller bearing weight, the dismounting activity space is little, problem such as recovery utilization rate is low, and the utility model provides a kind of extracting tool that is used for the nonstandard roller bearing of rolling machinery final drive shaft universal-joint spindle.
The technical scheme that its technical problem that solves the utility model adopts is: the extracting tool of nonstandard roller bearing is made up of the threaded stretching round bar of wind, head band round end and afterbody, leading screw body, leading screw, thrust bearing.Described leading screw afterbody connects thrust bearing and contacts with the spider center; Described two head band round ends, the threaded stretching round bar of afterbody tighten in the screw of any two symmetries on the roller bearing body; Described head band round end, the threaded stretching round bar of afterbody can move adjusting position along the rectangular channel on the leading screw body; Described wind is installed in the circular hole of stretching round bar top.During work, at first unload threaded roller bearing gland on the universal-joint spindle ear seat, continue to unload 6 M8 dormant bolts on the roller bearing body then, take off the roller bearing loam cake, dismounting specific purpose tool with this roller bearing bearing is positioned over removed position as follows at last: leading screw afterbody thrust bearing contact spider center, with 2 head band round ends, the threaded stretching round bar of afterbody tightens in the screw of any two symmetries on the roller bearing body, the stretching round bar can move adjusting position along the rectangular channel on the leading screw body, carry out above work, wind in the circular hole of turn stretching round bar top is till the roller bearing body all takes out from the ear seat.
The utility model is applicable to the dismounting of similar bearing under the similar operating mode, is particularly useful for removing and installing the bearing between axis hole.Rolling mill bearing dismounting for heavier can increase the length of wind as required, and then increases the rotation arm of force, ARTIFICIAL FORCE is reduced, until dismantling this bearing smoothly.Be the leading screw body, can it can be made three-jaw or two claw type formulas as required, the dismounting principle is identical.
The beneficial effects of the utility model are, it is big fully to have overcome nonstandard roller bearing weight, the dismounting activity space is little, the low deficiency that waits of recovery utilization rate, can simple and reliablely finish the dismounting recovery operation of nonstandard roller bearing, and this tool processes making is simple, it is time saving and energy saving to use, and, make performance of enterprises raising in various degree for enterprise saves a large amount of maintenance costs.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the nonstandard roller bearing detaching structure of mill's main drive shaft universal-joint spindle figure
Fig. 2 is a milling train roller bearing installation diagram
Fig. 3 leading screw body figure
Among the figure: 1. wind 2. head band round ends, the threaded stretching round bar 3. leading screw bodies of afterbody 4. leading screws 5. universal-joint spindle ear seats 6. roller bearing bodies 7. thrust bearings 8. cross axles 9. roller bearing glands 10. roller bearing loam cakes 11. connect dormant bolt 12. rollers 13. locating rings
The specific embodiment
By shown in Figure 1, at first unload threaded roller bearing gland 9 on the universal-joint spindle ear seat 5, continue to unload 6 M8 dormant bolts 11 on the roller bearing body 6 then, take off roller bearing loam cake 10, dismounting specific purpose tool with this roller bearing bearing is positioned over removed position as follows at last: leading screw 4 afterbody thrust bearings 7 contact cross axles 8 centers, with 2 head band round ends, the threaded stretching round bar 2 of afterbody tightens (annotate: this screw is on the former body and cooperates screw with 6 M8 dormant bolts) in the screw of any two symmetries on roller bearing body 6, stretching round bar 2 can move adjusting position along the rectangular channel on the leading screw body 3, carry out above work, wind 1 in the turn stretching round bar 2 top circular holes is till roller bearing body 6 all takes out from ear seat 5.
