However, by Figure 8 It can be seen that if the outer peripheral surface of the bearing cap 104 protrudes outward in the radial direction, the outer peripheral surfaces of the bearing caps 104 of a pair of Oldham couplings 100 arranged vertically close to each other interfere with each other, so the effective contact length B cannot be increased.

Abstract

The invention relates to a main shaft device for a calender. A recess is formed between adjacent bearing caps of the first Oldham coupling, and the recess is formed by the outer surface of the mounting portion of the bearing frame being recessed toward the central axis side than the outer surface of the bottom of the bearing cap. The pair of first Oldham couplings is arranged so as to have a predetermined phase difference in the rotation direction centering on the central axis, and the outer surface of the bearing cap of one of the first Oldham couplings enters the other first Oldham coupling. The recessed part of the device.

Description

technical field [0001] The present invention relates to a main shaft device for a calender. Background technique [0002] For example, a calender for iron and steel includes a pair of upper and lower rolls, a drive source for driving the pair of rolls to rotate them, and a spindle device provided between the rolls and the drive source. The main shaft device includes a pair of drive shafts and a pair of Oldham couplings. The drive shaft is rotated by a drive source. The Oldham coupling connects the driving shaft and the rollers. The main shaft device transmits the rotation of the drive shaft to the rolls in a state where the rolls are allowed to move up and down with respect to the steel material being rolled through the Oldham coupling (for example, refer to JP-A-2000-42614). [0003] Figure 8 It is a sectional view showing a pair of conventional Oldham couplings 100 . The Oldham joints 100 are arranged to be close to each other in the vertical direction. Each Oldham c...
