Improved means for counterbalancing the upper working roll in mill-stands

... 646,822. Rolling. BOHLER, V. Dec. 18, 1947, No. 33478. Convention date, Dec. 19, 1946. - [Class 83 (iv)] In a rolling-mill the upper roll 2 is connected to counterweights 7, 8 by pull members 4 which are led over rollers 5 and lie outside the mill stand. The weights are longer than the overall length of the rolls and journals. When changing the roll the weight of the counterweights is taken, with the upper roll in its lowest position, on chains 10 which are then transferred by a crane from hooks 12 to hooks 13, thus slackening the members 4. The base of the millstand is closed to prevent the entry of scale, water, &c.

POWER TOOLS

Counterbalanced recipocating mechanism.

The motor drives the crown gear which has an upwardly projecting eccentric drive pin which drivingly engages the channel fixed on the spindle which reciprocates in the fixed tube and supports a saw blade. The induced vibration is counterbalanced by the reciprocating counterbalance which slides on the outside of the tube. The crown gear has a cylindrical drive member which engages the cylindrical hole in the transfer block. The transfer block is moved in an orbital path and the opposed parallel sides engage and reciprocate the counterweight. The crown gear and cylindrical drive member have material removed to counterbalance the two drives.

PISTON BALANCING SYSTEM

A piston pump or compressor has a dynamically balanced drive assembly in which nearly all of the rotational, oscillatory and axial forces on the rotating drive shaft are canceled. The piston is primarily balanced by adding an oscillating counter weight mounted to the connecting rod to convert oscillatory forces into rotational forces at the axis of an eccentric element mounting the piston to the drive shaft. The remaining unbalanced rotational forces are centered along the drive shaft by a rotating counter weight. A further counter weight is mounted to the drive shaft spaced along the drive shaft from the rotating counter weight to impart a counter moment on the drive shaft and essentially cancel the moment about a moment axis perpendicular to the drive shaft resulting from the axial spacing of the piston and the other two counter weights. A method of reducing vibration on a piston drive shaft is also disclosed.

The scroll compressor of the present invention does not cause the breakage of both vortices even under any circumstances without complicating the manufacturing assembly process, and even if the slide key is minutely rotated in the slide hole by the drive of the drive shaft, The counterweight 35 protrudes the slide key 34 so as to smooth the adjustment by the slide and prevent the occurrence of uneven wear in the slide hole, and is opposed to the large diameter inner end 33a of the retaining shaft 93. The driving bush 36 is fitted to the slide key 34 so that the slide key 34 can slide infinitely in the direction in which the eccentricity R increases and in the direction in which the eccentricity R decreases. Since 35) is a separate component, it is easy to manufacture and assemble. 또한 구동부시(36)가 직선의 활주에 의한 조정을 하여도, 카운터 웨이트(35)는 구동부시(36)와 함께 이동하지 않아서, 과대한 하중이 구동부시(36)에 작용하는 만일의 사태시 두 와권체(23,42)의 충돌을 확실하게 방지한다. 그리고, 슬라이드 구멍(135a,136a)에서 활중하는 슬라이드 키(134)의 활주면 단부가 곡률 r의 연속된 곡면으로 모떼기 되어 있기 때문에, 구동축의 구동에 의해 슬라이드 키(134)가 슬라이드 구멍(135a,136a)안에서 미소하게 회전 운동하더라도, 슬라이드 키(134)가 가장자리 접촉을 하지 않고 매끄럽게 활주한다. In addition, even if the drive bush 36 adjusts by a straight slide, the counterweight 35 does not move with the drive bush 36, so that in case of emergency in which an excessive load acts on the drive bush 36, The collision between the two swirling bodies 23 and 42 is reliably prevented. Since the slide surface ends of the slide keys 134 that are active in the slide holes 135a and 136a are chamfered into a continuous curved surface of curvature r, the slide keys 134 are driven by the drive shafts. Even with a ...
