Further improvement as the utility model; Said rolling bearing assembly comprises thrust ball bearing, back-up ring and snap ring; Thrust ball bearing and shield ring sleeve on the axle journal of veneer reeling machine top working roll and be loaded on the volume conic tube in, thrust ball bearing one side withstand the volume conic tube on, the thrust ball bearing opposite side blocks through back-up ring; Back-up ring is spacing through the snap ring that is installed on the veneer reeling machine top working roll, is connected with screw between back-up ring and the snap ring.
As the further improvement of the utility model, described positioning key and friction key all are to be installed in the keyway of volume conic tube through the mode of attachment screw with movable dismounting.
As the further improvement of the utility model, between said volume conic tube and the veneer reeling machine top working roll composite bush is housed also.
The utility model compared with prior art; Advantage is: (1) is installed on the veneer reeling machine top working roll owing to friction key; When rolling (except during pre-bending) veneer reeling machine top working roll all the time with two bottom working roll symmetries, so no matter which bottom working roll the fanning strip end moves to, its fulcrum is all the time at the medium position of friction key; Make and the accurate positioning of fanning strip on veneer reeling machine improved the precision that rolls cylindrical shell.(2) because the frictional resistance of fanning strip is provided by friction key, the friction key volume is little, make simple and cost low, friction key can make things convenient for quick replacing during because of wear out failure, can improve production efficiency of equipment, has reduced manufacturing cost and maintenance cost.
