Abstract

1308233 Flying shears ZDARSKE STROJIRNY A SLEVARNY NARODNI PODNIK 30 April 1970 [4 May 1969] 20742/70 Heading B3W A rotary flying shear comprises upper and lower shear drums and drive means including a first gear 15 fast with the upper drum 1 and in mesh with a second gear 16 which is coupled to the lower drum 2 by a coupling 20 having two spaced sets of teeth, one set engaging teeth on the inner face of gear 16 and the other engaging a bush 19 fixed to the spindle of drum 2. Play between gears 15 and 16 is resiliently limited by a gear 17 spring-urged against gear 15. Play between the sets of teeth of coupling 20 and the bush 19 and gear 16 is resiliently limited by a spindle 21 having teeth, similar to those on coupling 20, in mesh with teeth in bush 19 and carrying, outside the coupling 20, a hub 22 which has teeth, similar to those on coupling 20, in mesh with teeth on the inner face of gear 16. Springs 24 act between the second hub member 23 on the spindle and the hub 22 to maintain continuous contact between the teeth of the coupling and those of the bush 19 and gear 16. The upper drum 1 is mounted in bearings 10, spring-loaded tension rods 12 taking the weight of the drum. The lower drum 2 is mounted in bearings 11 in adjustable blocks 6, 6<SP>1</SP>. The cutting clearance between the drums can be varied by means of eccentric rods (40), (41), Fig. 3 (not shown), mounted in bearings (44), (45) in the machine frame 7, 7<SP>1</SP> and in bearings (46) in extensions of the blocks 6, 6<SP>1</SP>. The rods are releasably connected at (53), (54) to permit independent adjustment and are rotatable through gears (47), (48) by a hand wheel (49) to move the blocks and thus vary the lateral position of the lower drum. Play in bearings (44)-(46) is resiliently limited by spring- tensioned rods (37), Fig. 2. To vary the vertical overlap of the drums adjustable wedges 28, 29 are located in recesses in the blocks 6, 6<SP>1</SP>. A pointer (31), Fig. 2 (not shown), attached to one of the blocks indicates the overlap on a scale (32) connected to the corresponding wedge. Miss-cutting is provided for by an eccentric spindle 35 on which the blocks 6, 6<SP>1</SP> are indirectly supported through the wedges 28, 29 and rollers 33.
