In order to overcome the deficiency that existing technology exists; The purpose of the utility model is to provide a kind of special flange bearing that is used to connect location outside saw blade and inboard saw blade, realize to outside saw blade and inboard saw blade reliable location, make good stability, the integrated rotation that cooperates closely, rotate reliable, long service life is to cutting composite saw blade.
For reaching above purpose, the rotation that the utility model provides to cutting composite saw blade with flange bearing is: be made up of inner ring 1, outer ring 2, ball 3, retainer 4 and Sealing 5; Defining an end face vertical with the flange bearing spin axis is left surface, and another relative end face is a right flank.Inner ring flange step surface 11 is set on the left surface of inner ring 1; Outer ring flange step surface 21 is set on 2 left surfaces of outer ring, the fixing threaded hole 12 of at least three circumference uniform distributions is set on the axial locating surface of inner ring flange step surface 11, fixing threaded hole 12 is towards left surface; The screw thread step hole 22 of at least three circumference uniform distributions is set on the axial locating surface of outer ring flange step surface 21; On the endoporus of inner ring 1, be provided with and drive keyway 13.The axial locating surface of inner ring flange step surface 11 is parallel with the axial locating surface of outer ring flange step surface 21, and the while is perpendicular to the spin axis of flange bearing.
Inner ring flange step surface 11 is used to locate and fixes rotation to cutting the outside saw blade of composite saw blade; Outer ring flange step surface 21 is used to locate and fixes rotation to cutting the inboard saw blade of composite saw blade.On the endoporus of inner ring 1, being provided with and driving keyway 13 is as driving with the engagement of outside saw blade live axle.
The further improvement of the utility model is that also the axial locating surface of inner ring flange step surface 11 is higher than the left surface of outer ring 2; The distance that exceeds is 0.01 to 0.3 millimeter.Purpose is to keep the working clearance in order to guarantee to assemble between back outside saw blade and the inboard saw blade.
The further improvement of the utility model is that also screw thread step hole 22 is the tapped hole of diameter than small end near left surface one end, is the bigger unthreaded hole of diameter near right flank one end.Screw thread step hole 22 is used to connect fixing inboard saw blade, and the unthreaded hole that right flank one end diameter is bigger is used as the drive pin couple drive with inboard saw blade live axle output terminal.
The beneficial effect of the utility model is:
Rotation in the utility model is used for position rotating to cutting the outside saw blade of composite saw blade to cutting composite saw blade with the inner ring flange step surface of flange bearing; Outer ring flange step surface is used for position rotating to cutting the inboard saw blade of composite saw blade; Through the connection location of flange bearing, the rotation that is made for one is to cutting composite saw blade; The rotating center of the blue bearing of outside saw blade and inboard saw blade winding is rotated freely; The Location accuracy and the rotation precision of outside saw blade and inboard saw blade have greatly been improved; When having avoided outside saw blade and inboard saw blade to rotate in opposite directions, the frictional heat between saw blade, interference and collision; Having avoided being cut material simultaneously piles stifled between outside saw blade and inboard saw blade; The rotation that makes steady, the efficient cut-out of sawing running, long service life, stable performance safety is to cutting composite saw blade.
