Abstract
The utility model relates to a torpedo tank car wheel set bearing mounting traction device, which is characterized by comprising a wheel set bearing mounting traction positioning device and a wheel set bearing pressing sleeve device, wherein the traction positioning device is a traction sleeve; the pressing sleeve device is a pressing sleeve; the traction sleeve is in U shape; the pressing sleeve is in a U shape; and the bearings are pressed in place at a time through the U-shaped pressing sleeve. The torpedo tank car wheel set bearing mounting traction device is simple in structure, novel in design, safe, reliable, convenient to operate and low in cost; the traction device is not provided with a complex part and is only structurally changed on the basis of the prior art, and the problems in the prior art are solved; and moreover, the damage rate of a middle space ring is reduced in the assembling process, the cost is saved, the labor intensity is reduced, and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of installation draw-gear, is applicable to the assembling of torpedo tank car wheel set bearing, relates in particular to a kind of torpedo tank car wheel set bearing draw-gear is installed, and utilizes this device to be assembled into bearing in the bearing housing fast.
Background technology
Existing torpedo tank car, each car have 16 pairs of wheels right, have 32 bearings, for large-scale steel plant; Needed the vehicle of overhaul to have 4 at least in every month, the bearing that needs to change has 128 bearings at least, but in the prior art, because of torpedo pot iron waterwheel wheel set bearing is split type; Mainly form, be installed to wheel to bearing housing on the axle journal earlier, bearing is installed again, because middle spacer ring is in the middle of two bearings by cartridge housing, two conical bearings, middle spacer ring etc.; In the spacer ring maximum gauge equate in bearing inner race, stayed certain glade plane space, be not installed to wheel to axle on the time; It can hang, and stops press-fiting of another bearing, at this moment needs manual work to do back work aside; Otherwise the damage of spacer ring in causing easily, such assembling bearing is not only more consuming time, has also increased operator's workload.Because there is certain defective in the bearing installing/dismounting, the middle spacer ring when being exactly the bearing assembling between the two bearings is installed relatively difficulty, because middle spacer ring internal diameter equates with wheel shaft; But external diameter is less; It is moving between two bearings, to exist string, and bearing housing can not be assembled on the wheel shaft fast, has had a strong impact on the maintenance progress of torpedo tank car; Even influenced equipment stop using and molten iron transports, also influenced the large-scale production of company simultaneously.If can not correctly be installed to bearing in the bearing housing, will have influence on the service life of bearing, stayed a potential safety hazard also for the torpedo tank car job run.Therefore, a kind of device of exigence solves above-mentioned technical problem.
Summary of the invention
There is certain defective in the technical problem that the utility model solved to prior art middle (center) bearing installing/dismounting just; Be exactly that middle spacer ring between bearing when assembling two bearings is installed relatively technical barrier such as difficulty and provided a kind of simple in structure; Easy to operate, lower-cost torpedo tank car wheel set bearing is installed draw-gear.
The technical scheme of the utility model is following; A kind of torpedo tank car wheel set bearing is installed draw-gear; It is characterized in that said installation draw-gear comprise wheel to bearing traction positioner and wheel to the bearing press mounting covering device, said traction positioner is a traction casing, press-fits suit and is changed to and press-fits cover.
As a kind of improvement of the utility model, said traction casing is arranged to " U " the type traction casing, saidly press-fit cover and be arranged to " U " type and press-fit cover, should " U " type press that shape cover is disposable to put bearing press mounting in place.
As a kind of improvement of the utility model, " U " type traction casing diameter is less than the diameter of vehicle wheel to axle journal, and said vehicle wheel is provided with bolt to axle journal.The traction casing diameter is convenient to put in advance vehicle bearing and middle spacer less than the diameter of vehicle wheel to axle journal.
As a kind of improvement of the utility model, " U " type traction casing bottom is provided with the bolt hole that the axle journal upper bolt hole is used with vehicle wheel.
Existing for prior art, this torpedo tank car wheel set bearing installation draw-gear advantage is following: simple in structure, and modern design, safe and reliable, easy to operate; Cost is lower, and this draw-gear only is to change to structure on the basis of existing technology not by the parts of complicacy, has just solved a difficult problem of the prior art; In assembling process, reduce the spoilage of centering spacer ring, practiced thrift cost, reduced labour intensity, improved operating efficiency.
Description of drawings
Fig. 1 press-fits the cover cutaway view for " U " type;
Fig. 2 is " U " type traction casing cutaway view;
Fig. 3 is a vehicle bearing process of assembling structural representation;
Among the figure: 1 press-fits cover for " U " type, and 2 is " U " type traction casing, and 3 is vehicle bearing, and 4 is the pressing machine piston, and 5 is middle spacer ring, and 6 is that vehicle wheel is to axle journal.
The specific embodiment
In order to deepen understanding, do detailed explanation below in conjunction with the novel installation draw-gear of 1-3 pairs of bases of accompanying drawing, referring to Fig. 1-3 to the utility model.
Embodiment 1: press-fit direction shown in Fig. 3 arrow: adopt the 16mm steel plate as the material that press-fits cover 1 and traction casing 2; The needs that traction press-fits according to bearing are designed to " U " type shape, and " U " type traction casing 2 diameters are slightly less than vehicle wheel to axle journal 6 diameters, are convenient to put in advance vehicle bearing 3 and middle spacer 5; The bolt hole of three ￠ 22mm that process in the bottom of " U " traction casing 2; This bolt hole is connected with the bolt hole of vehicle wheel to three ￠ 22mm on the axle journal 6, puts vehicle bearing 3 and middle spacer ring 5 well on " U " type traction casing 2 by assembling sequence, and stays a spot of gap; Be convenient to the installation of vehicle bearing 3 and middle spacer ring 5; At this moment pressing machine piston 4 slowly send " U " type to press-fit cover 1 in the top, and middle spacer ring 5 just can not hinder the installation of bearing because of deadweight falls down in assembling process; Spacer ring 5 in also can not damaging by pressure simultaneously, vehicle bearing 3 can be quickly installed in the bearing housing with middle spacer ring 5.Practice shows, adopts the utility model torpedo tank car wheel set bearing draw-gear can assemble bearing fast, reduces the spoilage of centering spacer ring in the assembling process, practices thrift cost, reduces labour intensity.
Need to prove; The foregoing description only is the preferred embodiment of the utility model; Do not limit the protection domain of the utility model; That on said structure, is made is equal to replacement or changes the protection domain that all falls into the utility model, and the protection domain of the utility model is as the criterion with claims.
