Split type roller structure with oil grooves

Abstract

The invention discloses a split type roller structure with oil grooves. The split type roller structure with the oil grooves comprises two rollers A, two rollers B and a roller C, wherein the rollers A, the rollers B and the roller C are installed coaxially, the two rollers B are symmetrically arranged on shaft shoulders of the roller C relative to the center line of the roller C and are combined with the roller C to form a half-round working surface, the two rollers A are arranged on the outer sides of the shaft shoulders of the roller C relative to the center line of the roller C and are connected to the roller C through bolts, the rollers B and the rollers A at the corresponding positions are connected through bolts, and the rollers A, the rollers B and the roller C form a whole in the processing process of split rollers. In the axis directions of the rollers B, the multiple annular oil grooves are formed in the inner side surfaces and the outer side surfaces of the rollers B and communicate with one another through multiple linear oil grooves located in the radial directions and the axial directions of the rollers B. The rollers A are provided with oil nozzle installation holes, and the oil nozzle installation holes communicate with the annular oil grooves in the outer side surfaces of the rollers B.

Description

technical field [0001] The invention discloses a split roller structure with an oil groove. Background technique [0002] In the design process of the roll, some welded pipes have very high requirements on the surface quality, but in the rolling process, the phenomenon of sticky material scratches caused by the difference in line speed always exists, which requires us to make the roll into a separate structure. Such as figure 1 As shown, the A roller and the C roller are connected together by bolts. At the same time, the inner hole of the roller has a keyway, and the shaft with power rotates at the same time through the key connection, which is equivalent to a whole roller. The B roller is passed through the inner hole and the C roller. The shaft shoulders on the side cooperate with each other and passively rotate under the drive of the strip steel, which also solves the sticking phenomenon caused by the difference in line speed at the contact point between the edge of the ...

Problems solved by technology

However, during the operation of the roll, the two sides and the inner hole of the B roll have relative friction with the A roll and the C roll, so that the rotation is not smooth
