Sankyo Seisakusho Co. | Date: 2017-01-18

A sheet material feeding apparatus includes a first roll 106, and a second roll 108 arranged vertically below first roll 106, to feed a sheet material clamped between the first roll 106 and the second roll 108. The sheet material feeding apparatus further includes a first motor 102 provided with a rotatable first motor shaft 104 coupled to the first roll 106, and a second motor 103 provided with a rotatable second motor shaft 105 coupled to the second roll 108. The first motor shaft 104 and the second motor shaft 105 rotate at substantially the same rotation speed to allow the first roll 106 and the second roll 108 to rotate in synchronization with each other.

There is provided a buildup device (1) that builds up a plate-shaped core after rotating the core by a predetermined angle, and that includes a servomotor (11), a damping plate (25) attached to the servomotor, at least one upper plate (21) provided above the damping plate, at least one lower plate (22) provided below the damping plate, and a plurality of vibration absorbing members (31) attached to the damping plate. The upper plate and the lower plate restrict a degree of freedom of vibration to one direction, and the vibration absorbing members absorb vertical vibration.

Provided is a strain wave gearing apparatus which is able to make the most of the structural advantages of the flat form while achieving ideal mesh-engagement without involving a high degree of dimensional precision or any special adjustment mechanism. A strain wave gearing apparatus 1 is provided with a stationary internal gear 3, a rotary internal gear 11 disposed side by side with the stationary internal gear, a flexible planetary gear 19 disposed on the inner peripheral side thereof for meshing partially with the internal gears by being deflected in the radial direction, and a wave generator 27 disposed inside the flexible planetary gear for continuously deforming and deflecting the flexible planetary gear by rotation. In the apparatus, backlash during mesh-engagement is eliminated by making the base portions 5 and 13 of the internal gears 3 and 11 elastic.
