Background technology
Aluminium Strips with High Precision paper tinsel stretch-bending straightening unit is the key equipment of band finishing aligning, also is the most effective equipment that improves band plate shape and surface quality, and the sixties in last century develop rapidly abroad, and are comparatively universal now.At present, domestic Aluminium Strips with High Precision paper tinsel stretch bending-straightening machine is mainly produced by German INA company with the support roller combining structure, and for reducing cost, production domesticization equipment is all being sought by each enterprise.The Aluminium Strips with High Precision paper tinsel stretch bending-straightening machine support roller combining structure of this project development, because it is had relatively high expectations to sealing, running accuracy etc., difficulty of processing is big, domestic still do not have mature technology at straightener on the design of support roller combining structure and manufacturing.
Summary of the invention
For overcoming the defective that exists in the prior art, the invention provides a kind of support rolling wheel composite structure of flattener,, adopt multi-sealed and the self-lubricating of diameter of axle oil circuit by optimizing type selecting, effectively guarantee rotating accuracy and specification requirement, satisfied the accurate support of Aluminium Strips with High Precision paper tinsel stretch-bending straightening unit.
For achieving the above object, the following technical scheme of the present invention's employing:
A kind of support rolling wheel composite structure of flattener, it mainly is made of needle bearing assembly, thrust bearing assembly, end cap and lubricating system; Described needle bearing assembly is made up of axle, axle sleeve, cages for needle and needle roller, and described axle sleeve two ends are the symmetrical structure setting, and the axle sleeve two ends respectively have two draw-in grooves that are stepped ramp type; Needle roller is installed in the centre of axle sleeve two ends draw-in groove and axle by cages for needle; Described thrust bearing assembly is made up of thrust circle I, thrust circle II, ball retainer and steel ball, thrust circle I is installed in by being tightly fixed in first draw-in groove on the axle sleeve of needle bearing assembly, thrust circle II is installed on the axle of needle bearing assembly, and steel ball is installed between thrust circle I and the thrust circle II by ball retainer; Be processed with a groove on the internal diameter of described thrust circle II, device one O RunddichtringO in the groove; The second draw-in groove place corresponding to axle sleeve on the external diameter of described thrust circle II is processed with mechanical labyrinth type groove, and described thrust circle II constitutes mechanical labyrinth type loop seals with the end cap that is fixedly mounted on the axle sleeve of needle bearing assembly; Multi-sealing structure is formed in described mechanical labyrinth type loop seals and the sealing of O type circle.
Described support rolling wheel composite structure of flattener, its lubricating system, processing one central blind hole on axle one end of needle bearing assembly, and be communicated with radial hole corresponding to needle roller, the end of central blind hole is installed with the press-fit forced filling oil cup.
Described support rolling wheel composite structure of flattener, the technical process of its assembling is:
The needle roller that will be installed on the cages for needle is assemblied on the axle earlier, and the axle sleeve correspondence that a thrust circle I is housed in the draw-in groove at one end is installed on the needle roller; Then another thrust circle I is installed in the draw-in groove of axle sleeve, and being installed in the outside that steel ball on the steel ball retainer is positioned over thrust circle I respectively, two thrust circle II that the O RunddichtringO will be housed again are installed on the outside of steel ball respectively; At last end cap is installed in the sleeve end draw-in groove, and the press-fit forced filling oil cup is installed in the end of the central blind hole of axle.
Because the present invention has adopted as above technical scheme, it has following good effect:
This support rolling wheel composite structure of flattener, owing to adopt the combination of needle bearing and thrust ball bearing, realized that Aluminium Strips with High Precision paper tinsel stretch bending-straightening machine can bear bigger radial load with the support roller combining structure and can bear certain axial force again in limited structure space; Adopt mechanical labyrinth type loop seals, the sealing of O type circle, guaranteed dustproof, grease proofing seal request; It is lubricated convenient simultaneously, and the running accuracy height is convenient to safeguard.This technology has been filled up the technological gap that China uses the design of support roller combining structure and makes at straightener.
