Embodiment
For making the object, technical solutions and advantages of the present invention clearly, will be described in detail technological scheme of the present invention below.Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, other mode of executions all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope that the present invention protects.
As depicted in figs. 1 and 2, the invention provides a kind of rolling kneading machine support roller assembly, comprise bearing support 1, bearing, bearing shaft 3 and be injection-moulded in the nylon jacket 2 of bearing support 1 outer cylinder surface., bearing shaft 3 is arranged in bearing support 1 by bearing, and bearing is fixedly mounted in the bearing chamber of bearing support 1 by flange 5, the outer cylinder surface of bearing support 1 is injected with nylon jacket 2.Nylon jacket 2 is injected on the outer cylinder surface of bearing support 1 by coarse thread.Pot body stable movement can be made to reduce the wearing and tearing of bearing by the outer cylinder surface injection molding nylon cover 2 at bearing support 1, increase the service life; Get on the bus at the outer outer cylinder surface of bearing support 1 and be shaped with coarse thread, the frictional force between bearing support 1 and nylon jacket 2 and adhesion can be strengthened, prevent from sliding between nylon jacket 2 and bearing support 1, reduce wearing and tearing, make rolling kneading machine work more stable, the material of nylon jacket is TW36 (PA46), is characterized in that intensity is high, wear-resisting property good, high temperature resistant, good springiness.
The material of nylon jacket 2 is the nylon composite materials of PA46TW363, and this kind of material is wear resistant, and performance is high, has certain elasticity, a pot body is operated steadily in operation process, long service life, safe and reliable.The material of bearing support 1 is No. 45 middle-carbon steel.During Vehicle Processing, the bearing chamber that clamped one time one train goes out two ends can ensure its coaxality requirement, meets the running accuracy of bearing.
Bearing is tapered roller bearing 4, the outer ring of tapered roller bearing 4 is arranged in bearing chamber by flange 5, the inner ring of tapered roller bearing 4 is limited in bearing chamber by the step in bearing shaft 3, in bearing support 1, tapered roller bearing 4 is installed, is improved running accuracy and the working life of bearing by flange., be drilled with oil hole 7 in bearing shaft 3, the outer openings end of oil hole 7 be provided with oiling sealed mouth 8, by drilling oil outlet in bearing shaft 3, conveniently to the indoor injection lubricant oil of bearings at both ends, the convenience of work can be improved.What adopt in the design is 30307 type tapered roller bearings, adopts this 30307 type tapered roller bearing can be adjusted the axial displacement of outer ring by the change of flange gasket thickness, thus eliminates radial clearance, improves running accuracy and the working life of bearing.
The bearing that rolling kneading machine support roller assembly structure of the present invention is simple, bearing lubrication convenient, select can bear the radial and axial load of pot body simultaneously.Be provided with the pad of adjustable thickness between flange 5 and bearing support 1, the thickness changing pad can make bearing outer ring produce axial displacement, eliminates the radial clearance of bearing, improves running accuracy and the working life of bearing.
Be separately installed with two cover supporting wheel assemblies in upper support frame front-axle beam right and left, two assembly mechanism right position are adjustable.Newly-designed support roller selects the 30307 type tapered roller bearings that simultaneously can bear the linear contact lay of radial and axial joint load.By the adjustment of axial flange 5 planchet thickness, preload can be applied to bearing, improve the running accuracy of bearing and the working life of bearing.The processing technology of bearing support 1 is simple, and clamped one time can go out the bearing chamber at two ends by a train, meets the coaxality requirement of bearings at both ends room.Former support roller selects 6307 type point cantact deep groove ball bearings, and this bearing shaft is very poor to ability to bear, does not have radial internal clearance adjustment function, under the unbalanced swing of pot body and axial float, and the very fast fatigue failure of bearing.The coaxality processing difficulties of bearing support 1 bearings at both ends room.One end of bearing shaft 3 is drilled with
aperture, can very easily in non-stop-machine situation lubricating grease injection bearing, the normal work of rolling kneading machine can be ensured.Filling passage arranges oiling sealed mouth, prevents lubricating grease excessive.
The steep-lead thread of bearing support 1 outer cylinder surface M120x6, manufacturing process is simple, to frictional force and the strong adhesion of nylon, nylon jacket 2 work safety, reliable on bearing support 1, difficult drop-off.Nylon jacket 2 material is TW363 (PA46 series nylon composite materials).This kind of material is wear resistant, and performance is high, has certain elasticity, a pot body is operated steadily in operation process, long service life, safe and reliable.
The support roller assembly that the design makes, is characterized in that processing technology is simple, makes precision high.The steep-lead thread of M120x6 is had at the outer surface car of bearing support, manufacturing efficiency is high, and each only needs can complete for 10 minutes, and this design one-pass just can complete and wholely leads into screw thread, do not need reciprocal toolsetting, and also very strong to the adhesion of nylon jacket.Outer cylinder surface adopts tooth-shape structure to be a kind of old-fashioned structure of eliminating, and that method processing technology complexity (at least needing 2 Working days) is very poor to the adhesion of nylon, easily produces on profile of tooth direction and slides.Bearing seat inner diameter processing technology has carried out very large improvement: bearing changes the tapered roller bearing of 30307 into by 6307 type deep groove ball bearings, and the coaxality of bearing support bearings at both ends room is guaranteed, the axial position of nylon jacket have also been obtained guarantee.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should described be as the criterion with the protection domain of claim.
