Description
Technical field
The utility model relates to a kind of maintenance tool of vertical type transmission case of high line pre-finishing mill, specifically, relates to a kind of high line pre-finish rolling vertical type transmission case import input shaft bearing puller.
Background technology
When repairing the vertical type transmission case of high line pre-finishing mill, often there is input shaft bearing cannot dismantle smoothly, the not easily changeable situation of new bearing, the dismounting and change of this bearing is the key of keeping in repair whole vertical type transmission case, and most of workload of vertical type transmission case maintenance concentrates on this.
This bearing of current dismounting adopts destructive way mostly, namely the inside and outside cover of bearing is sliced off with gas welding, this way not only efficiency is low, and very easily damage power shaft surface, on life-span of this axle and install fineness and create fatal impact, the scheme therefore fundamentally solving this bearing of dismounting is the task of top priority of this vertical type transmission case of rational maintenance.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high line pre-finish rolling vertical type transmission case import input shaft bearing puller, improves the efficiency of old bearing removal and installs the quality of new bearing.
The technical solution of the utility model is as follows:
A kind of high line pre-finish rolling vertical type transmission case import input shaft bearing puller, comprises two semi-cylindrical shape steel bushing monomers, the inwall of described steel bushing monomer is provided with the first draw-in groove and axial axial plane, outer wall is provided with the second draw-in groove; Described first draw-in groove and described second draw-in groove are along the axially-aligned of axis hole.
Further: two described steel bushing combination of monomers together after, described first draw-in groove and described second draw-in groove be annular, described axial plane forms described axis hole.
Further: the outer wall of described steel bushing monomer is provided with suspension ring.
Further: the lower surface of described first draw-in groove is for pushing away platform, and the top of described first draw-in groove is backplate.
Technique effect of the present utility model is as follows:
1, use of the present utility model, improves the efficiency of old bearing removal and installs the quality of new bearing, and then extending service life and the bearing replacing cycle of vertical type transmission case, decreasing the year spare parts consumption in this region.
2, use of the present utility model, shortens the time of casualty under emergency, alleviates the labour intensity of repairing workman, extends the vertical type transmission case servo period of spare unit and service time as a whole.
3, simple, light and handy, the easy making of the utility model lamps structure, feature easy to use.
Accompanying drawing explanation
Fig. 1 is the front view of steel bushing monomer in the utility model;
Fig. 2 is the top view of steel bushing monomer in the utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and be not used in restriction the utility model.
As shown in Fig. 1 ~ 2, the structure of high line pre-finish rolling vertical type transmission case import input shaft bearing puller comprises two semi-cylindrical shape steel bushing monomers 1, the inwall of steel bushing monomer 1 is provided with the first draw-in groove 101 and axial axial plane 103, the outer wall of steel bushing monomer 1 is provided with the second draw-in groove 102.After two semicircle steel bushing monomers 1 are combined, the first draw-in groove 101, second draw-in groove 102 is annular, and axial plane 103 forms axis hole, and the first draw-in groove 101 and the second draw-in groove 102 are along the axially-aligned of axis hole.
The lower surface of the first draw-in groove 101 is for pushing away platform 104, and the top of the first draw-in groove 101 is backplate 105.Push away platform 104 for promoting bearing shell in input shaft bearing, backplate 105 for the protection of the outer bearing shell of input shaft bearing, and for back off bearing time push the miscellaneous part at input shaft bearing rear portion open.
In preferred embodiment, steel bushing monomer 1 width is 130mm, is highly 195mm, and semicircle outer perimeter is 1256mm, and interior girth is 440mm.Steel bushing monomer 1 adopts 45# steel ingot to make.
For the ease of lifting, the outer wall of steel bushing monomer 1 is provided with suspension ring, and suspension ring are arranged on the center of gravity place of steel bushing monomer 1, are stuck on hydraulic means by this steel bushing monomer 1 during lifting by these suspension ring.
During use, wrap on axle by two semicircle steel bushing monomers, 1 degree of axial plane 103, bearing encases by the first draw-in groove 101, pushes away platform 104 and directly contacts with bearing inner sleeve as shaft strength face; Second draw-in groove 102 is stuck on hydraulic means, and the hydraulic cylinder push rod of hydraulic means withstands on the end of steel bushing monomer 1, and hydraulic cylinder push rod is had an effect to the first draw-in groove 101 direction by the second draw-in groove 102, and about several seconds rear bearing can be removed smoothly.Hydraulic means pressure is adjusted to 60 ~ 70Mpa by this process, can ensure enough thrust and be exited smoothly by bearing.Hydraulic means is conventional hydraulic means, comprises hydraulic cylinder push rod and the hydraulic cylinder providing thrust.
In sum, bearing puller of the present utility model for keeping in repair the vertical type transmission case of high line pre-finishing mill, reasonable removing damaged cone bearing.This bearing puller is by the contour structures of design steel bushing and in conjunction with hydraulic means, ingenious to be uniformly distributed each position stressed, by active force with reaction force with this puller as bridge transmission, effect plays obvious.Use this bearing puller, can bring direct economic benefit to be: 3000 yuan/cover (bearing price) × 3 cover/year+5000 yuan/cover (axis of cone price) ×+12 hours/years 2 cover/year (time of casualty) × 70 ton/hour × 150 yuan/ton of (single ton of profit)=14.5 ten thousand.。
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
