A clutch disc assembly is provided with a support structure and friction generating members that provide generally constant friction generation, even when misalignment occurs between adjacent members. The clutch disc assembly 1 includes a hub 2, a fourth friction washer 19, a clutch plate 3 and a second coil spring 7. The fourth friction washer 19 is fixed to the hub 2 and has a tapered surface 19a. The clutch plate 3 has an inner peripheral edge tapered portion 3c which is abutted against the tapered surface 19a and disposed on the outer periphery of the hub 2. The second coil spring 7 couples the hub 2 to the clutch plate 3 in a circumferential direction.

A plate rolling mill includes a pair of work rolls that hold and press down a plate material therebetween, a plurality of backup rolls that prevent the work rolls from being deformed, and intermediate rolls each of which is disposed between the work roll and the backup roll so as to be shiftable. Each of the intermediate rolls has a contact roll portion that contacts with the backup roll, and an extension barrel portion that is connected to an end of the contact roll portion and does not contact the backup roll at any shifted position. The contact roll is formed to have a convex shape such that a convex center of the contact roll is positioned at a side of the extension barrel portion.

The present invention makes it possible to detect efficiently and accurately small torque. A torque detector includes a first shaft portion (first torque detecting portion), a first strain gage, a second shaft portion (second torque detecting portion), and a second strain gage. The first strain gage is provided on the first shaft portion. The second shaft portion has lower rigidity than the first shaft portion. The second torque sensor is provided on the second shaft portion to measure smaller torque than the first strain gage.

A method for determining a shape of a shift roll for a rolling mill, includes the steps of determining a necessary control amount distribution αi for a plate crown with respect to plate widths, based on a distribution of the number of plates rolled by a target rolling mill with respect to plate widths, and providing a maximum radius difference yA0 of the shift roll. The method further includes the steps of preliminarily determining a line yi of a roll radius distribution with respect to plate widths, based on the necessary control amount distribution αi and the maximum radius difference yA0, shifting the line yi of the roll radius distribution by a maximum roll shift to obtain a distribution ΔyBi of a roll gap change amount with respect to plate widths under the maximum roll shift, and smoothing sharp local changing part of the distribution ΔyBi of the roll gap change amount.

摘要:
An apparatus for manufacturing a band plate has a rolling mill that includes a pair of upper and lower work rolls that roll a slab material having edge drop portions at both ends thereof, and a pair of backup rolls that contact non-rolling side surfaces of the pair of upper and lower work rolls, respectively to prevent the work rolls from being deformed. The work roll includes a reverse taper portion where a roll diameter gradually increases towards a barrel end portion thereof corresponding to the edge drop portion. The upper and lower work rolls are configured to be shiftable individually in the axial direction thereof. The backup roll includes an escape portion whose diameter gradually decreases towards an axial end thereof so as not to contact the reverse taper portion of the work roll, within a shifting range of the work roll.

A continuous press apparatus presses an electrode band plate having a band-shaped metal foil collector on which an electrode active material is formed at intervals in a longitudinal direction. The apparatus includes a pair of press rollers, gap adjusting means for adjusting a gap between the press rollers, detecting means for detecting that a rear end of the electrode active material portion arrives at the position between the press rollers, and the gap adjusting means adjust the gap between the press rollers in response to the detection.

A clutch disc assembly (1) is provided with lubrication members (11a, 11b) to reduce the wear of the parts which contact the large coil springs (7) disposed within the clutch disc assembly (1). Plates (4) and (5) and a separated flange (3) are configured to rotate relative to each other. Raised portions (4a) and (5a) of the plates (4) and (5) correspond to a window (3c). Each of the large coil springs (7) extends in a circumferential direction with respect to the clutch disc assembly (1). Each large coil spring is confined within a corresponding the window (3c) of the separated flange (3) and further between the raised portions (4a) and (5a) of the plates (4) and (5). Lubricant-impregnated members (11a, 11b) are provided on a portion of respective sides of the separated flange (3), and are contactable with the large spring coil (7). In one alternate embodiment, a portion of plates (105) and (106) is provided with a plurality of minute apertures (140). The plates (105) and (106) are then provided with a surface hardened layer (130) to reduce wear due to friction.
