摘要： A crank device can produce a large torque without increasing the locus of the crank arm. The crank arm has first and second arms which are longitudinally slidably coupled together through a pinion. The second arm is formed with two sets of rack teeth on both sides of the pinion. The pinion has along its circumference a plurality of teeth which are adapted to alternately come into meshing engagement with the respective sets of rack teeth every time the crank arm makes a half turn in the same direction. Thus, the entire length of the crank arm alternately becomes maximum and minimum every time the crank arm turns by 180.degree.. By applying a driving force to the crank arm when the length of the crank arm is maximum, it is possible to produce a large torque.
摘要翻译：曲柄装置可以产生大的扭矩而不增加曲柄臂的轨迹。曲柄臂具有通过小齿轮纵向可滑动地联接在一起的第一和第二臂。第二臂在小齿轮的两侧形成两组齿条齿。小齿轮沿其周边具有多个齿，每当齿轮在相同的方向上转动半圈时，该齿适于交替地与各组齿条齿啮合。因此，每当曲柄臂转动180°时，曲柄臂的整个长度交替变为最大和最小。当曲柄臂的长度最大时，通过向曲柄臂施加驱动力，可以产生大的转矩。

摘要： A crankshaft rolling machine rotatably guides a crankshaft to be rolled. At least one movable rolling fixture carrying rolling dies is positionally controlled by two synchronously driven rotatable cranks having parallel mounting shafts. Eccentric crank pins are coupled to the fixture. An adjustable connection is interposed between crank pins and mounting shafts of the cranks.

摘要： A stroke adjustment for reciprocating mechanisms which includes an external adjusting wheel to vary internally the longitudinal position of a carrier through an interconnected shaft and gear. A butterfly arm is pivotally connected to the power shaft and is pivoted by the carrier to raise or lower one end of a connected crank to vary the length of the piston stroke by changing the eccentricity of the crank.

摘要： The invention achieves a method and a device for providing infinitely variable adjustment to the throw of an eccentric from zero to a maximum while the eccentric is permitted to continuously travel in angular motion. This is achieved by two juxtaposed and eccentric members mounted on a drive shaft, one (the outer) overriding, the other (the inner). The eccentric members may be relatively positioned by a control shaft, which extends coaxially through the drive shaft, and gearingly mates with the outer eccentric member. The outer surface of the outer eccentric can be arranged (by relatively positioning the outer and inner eccentric members) to trace the loci of points of a circle, whereupon no reciprocation takes place, or of a family of ellipses of varying eccentricity, whereby reciprocation is achieved in correspondence to the relative eccentricity in the path of travel of the outer surface.

摘要： A hermetic reciprocating compressor such as may be used in heat pump applications is provided for dual capacity operation by providing the crankpin of the crankshaft with an eccentric ring rotatably mounted thereon, and with the end of the connecting rod opposite the piston encompassing the outer circumference of the eccentric ring, with means limiting the rotation of the eccentric ring upon the crankpin between one end point and an opposite angularly displaced end point to provide different values of eccentricity depending upon which end point the eccentric ring is rotated to upon the crankpin, and a reversible motor in the hermetic shell of the compressor for rotating the crankshaft, the motor operating in one direction effecting the angular displacement of the eccentric ring relative to the crankpin to the one end point, and in the opposite direction effecting the angular displacement of the eccentric ring relative to the crankpin to the opposite end point, this arrangement automatically giving different stroke lengths depending upon the direction of motor rotation. The mechanical structure of the arrangement may take various forms including at least one in which any impact of reversal is reduced by utilizing lubricant passages and chambers at the interface area of the crankpin and eccentric ring to provide a dashpot effect.In the main intended application of the arrangement according to the invention, that is, in a refrigerating or air conditioning system, it is desirable to insure a delay during reversal of the direction of compressor operation. A control arrangement is provided in which the control system controls the direction of motor operation in accordance with temperature conditions, the system including control means for effecting operation in a low capacity direction or alternatively in a high capacity direction in response to one set, and another set, respectively, of temperature conditions and with timer means delaying a restart of the compressor motor for at least a predetermined time in response to a condition of the control means operative to initiate a change in the operating direction of the compressor when it restarts.

摘要： Mechanism for adjusting the stroke length of a variable positive displacement pump at any time without stopping the operation of the pump. A drive shaft mounted on a frame drives a crank, and a bearing on the end of the crank rides in an elongated slot in a driving arm attached to a connecting rod which imparts reciprocating movement to the pump. The outer end of the driving arm is pivoted to a control arm which is rotatably adjustably mounted on the frame to change the orientation of the elongated slot with consequent change in the stroke of the connecting rod.
