Description
Technical field
The utility model discloses a kind of separated roller.
Background technology
In the design process of roll, some welded tubes are very high to the prescription on surface, but in the operation of rolling due to
The sizing that linear speed difference is caused scratches phenomenon to be present all the time, and this requires that we make roll the structure of split, as shown in figure 1, A
Roller and C rollers are bolted together, while the endoporus of C rollers has keyway and passes through key connecting with dynamic axle while rotating,
Equivalent to an overall roller, B rollers are cooperated by the shoulder axle of endoporus and C rollers both sides, are passively rotated under the drive of strip steel,
Also B rollers edge is just solved from the contact point of C roll shapes intracavity and strip steel due to the different and caused sizing phenomenons of linear velocity.But by
There is the requirement of dimensional tolerance in caliber, so for the relative position of B rollers and C rollers will also constitute an accurately circular hole,
It requires the necessary entirety numerical control turning in processing, it is ensured that precision during use, but as B rollers are passive, in turning
Relative slip can be produced with A, C roller.
