Problems solved by technology

Therefore, a pair of yokes 106 cannot be mutually used, so it is necessary to prepare two kinds of spare yokes 106 in which the mounting holes 112 are formed in different positions.
As a result, there is a problem that the purchase cost of spare parts increases

Embodiment Construction

[0031] Next, preferred embodiments of the present invention will be described with reference to the drawings. figure 1 It is a schematic side view showing a rolling machine provided with a main shaft device for a rolling machine according to an embodiment of the present invention. exist figure 1Among them, the rolling machine 1 of the present embodiment is constituted by, for example, a rolling machine for iron and steel that performs a rolling process on a steel material W. As shown in FIG. This calender 1 includes a pair of upper and lower rolls 2 , a motor 3 , a speed reducer 4 , and a main shaft device 5 for the calender. The motor 3 is a drive source that drives the respective rollers 2 to rotate in mutually opposite directions. The speed reducer 4 decelerates the rotation of the motor 3 . The calender main shaft device 5 is provided between the roll 2 and the speed reducer 4 .

[0032] The main shaft device 5 for a rolling mill transmits the torque output from the ...

Abstract

A spindle unit for a rolling mill includes: a pair of upper and lower drive shafts disposed between a pair of upper and lower rolls and a motor; a pair of upper and lower cross joints disposed between the rolls and the roll-side paired end portions of the drive shafts; and a pair of upper and lower tubular first yokes each having a connection portion formed at one axial end portion of the corresponding yoke and connected to the corresponding cross joint, and each having a fitting hole into which a rotary shaft of the roll is press-fitted, the fitting hole being formed in the other axial end portion of the corresponding first yoke and having a capsule-like sectional shape around an axis of the corresponding yoke. The first yokes are formed such that formation positions of the fitting holes with respect to the connection portions coincide with each other.

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, and a spindle device. The driving source drives and rotates the above-mentioned pair of upper and lower rollers in mutually opposite directions. The spindle device is provided between the roller and the drive source. The spindle device includes a pair of upper and lower drive shafts, a pair of upper and lower yokes, and a pair of Oldham couplings. The drive shaft is rotated by the drive source. The pair of Oldham couplings couples each drive shaft to the rotation shaft of each roller via the yoke. The main shaft device transmits the rotation of the drive shaft to the rolls through the Oldham coupling in a state where the rolls are allowed to move up and down with respect to the steel material being rolled (for example, refer to JP-A-2000-42614).
