Abstract
The invention discloses a roller comprising a barrel and a main shaft. A circular-arc-shaped R angle is arranged on the joint between the barrel and the main shaft. Compared with traditional technologies, the joint between the barrel and the main shaft is designed to be the concave R angle, so that a force-bearing point is made to shift outwards; and meanwhile, the rotation balance capacity of the roller is further improved by additionally adopting the circular ring design.
Description
Technical field
The invention belongs to iron and steel manufacturing technology field, be specifically related to a kind of roll.
Background technology
Roll is the strength member on steel rolling mill's rolling mill, and the pressure utilizing a pair or producing time one group of roll rolls is to roll stone roller steel, and it is primarily subjected to Dynamic And Static Loads during rolling, abrasion and the impact of variations in temperature.Traditional roll has plenty of the design of beam barrel one, and the connecting portion at main shaft Yu cylinder is the right angle of 90 °, but finds after specifically used, often produces the phenomenon of fracture in beam barrel junction, has had a strong impact on the service life of whole roll.
Summary of the invention
Goal of the invention: present invention aims to the deficiencies in the prior art, it is provided that a kind of roll.
Technical scheme: in order to reach foregoing invention purpose, the present invention is specifically performed by: a kind of roll, is provided with circular arc R angle including cylinder and main shaft, described cylinder and main shaft junction.
Wherein, described R angular cylinder sunken inside.
Wherein, described main shaft is provided with annulus.
Wherein, the main shaft of described cylinder both sides is equipped with annulus.
Beneficial effect: beam barrel junction, compared with conventional art, is designed to the R angle of depression so that stress point offsets laterally by the present invention, meanwhile, further increases balanced capacity during roll rotation by addition toroidal design.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
A kind of roll as shown in Figure 1, is provided with circular arc R angle 3 including cylinder 1 and main shaft 2, described cylinder 1 and main shaft 2 junction, and described R angle 3 is equipped with annulus 3 to cylinder 1 sunken inside, the main shaft 2 of described cylinder 1 both sides.
