摘要： An adjustable stroke mechanism has a housing with a central axis and a wall enclosing a cavity. At least one counterweight is movably disposed within the cavity. A mounting assembly is disposed within the cavity. The mounting assembly has a workpiece attachment mechanism. A stroke adjustor couples the at least one counterweight with the mounting assembly. The stroke adjustor enables the counterweight and mounting assembly to move with respect to one another such that a distance between the counterweight and the mounting assembly is variably adjusted which, in turn, variably adjusts a stroke radius of the workpiece attachment mechanism with respect to the central axis of the housing.

摘要： An adjustable crank assembly is provided. The adjustable crank assembly includes a crank arm having a surface with a plurality of notches, and a retention block that partially houses the crank arm and allows the crank arm to slide along an axis relative to the retention block. The retention block includes a clamping block and a locking pin, both of which being adapted to selectively engage the crank arm when the retention block is placed in a locked position, and a locking lever for transitioning between a locked position and an unlocked position. The locking lever provides a compressive force to the clamping block when placed in a locked position and a retracting force to the locking pin when placed in an unlocked position.

摘要： An internal combustion engine includes a crankshaft and at least one piston coupled to the crankshaft for executing strokes in a cylinder as a result of rotation of the crankshaft. An eccentric shaft is coupled to the crankshaft and to the piston in such a way that strokes of the piston are adjusted by the eccentric shaft. A phase adjuster adjusts a phase of the coupling of the eccentric shaft to the crankshaft.

摘要： A remote mount kit for a damper in an HVAC system is provided. The remote mount kit includes a mounting bracket. The mounting bracket includes a first mounting flange having a first mounting hole pattern and a second mounting flange having a second mounting hole pattern. The remote kit also includes a drive shaft having a first drive end and a second drive end. The first drive end and the second drive end are configured to couple to an actuator. The remote kit further includes a crank shaft and a connector configured to couple the crank shaft to the damper. A dimension between the holes of the first mounting hole pattern is smaller than a dimension between the holes of the second mounting hole pattern.

摘要： A motor vehicle with an internal combustion engine which is installed into a motor chamber in the longitudinal direction and which has a multi-joint crank drive with an eccentric shaft and a crankshaft starter is disclosed. The crankshaft starter is arranged relative to the internal combustion engine such that a longitudinal central cylinder plane, which is spanned by longitudinal central cylinder axes of the internal combustion engine, lies between the crankshaft starter and the eccentric shaft.

摘要： In a crankshaft of an internal combustion engine wherein a crankthrow is shortened by the use of a multi-link mechanism, the crankthrow from the axis of a main journal to the axis of a crankpin is set shorter than one-half of a piston stroke, and an oil passage is formed to supply lubricating oil to a bearing portion of the crankpin. The pin-side opening of the oil passage, which is open at the outer peripheral surface of the crankpin, is formed in ranges other than angular ranges of 0°, 90°, 180°, and 270° with respect to a reference line extending from the axis of the main journal toward the axis of the crankpin in a decentering direction of the crankpin, thereby alleviating a stress concentration caused by a torsional torque in the vicinity of the pin-side opening of the oil passage.

摘要： An operable angle adjusting structure for a wiper produces a maximally wide wiping angle is realized within the range where wiper arms will not interfere with window pillars and each other and will not require a precision machining apparatus. A drive link includes a ball joint disposed in one end portion, and the ball joint is integrally mounted to one surface of an adjusting member such that the center axis of the ball joint is eccentric with respect to the center of a screw hole by a specified distance. The adjusting member is turned to change the axis-to-axis distance between a wiper drive shaft and the ball joint for proper adjustment.

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。
