    • A transmission for reducing the pulley ratio between a drive shaft and a transmission shaft. The transmission is adapted to convert a higher speed rotary motion to a lower speed linear motion. The transmission has two pulleys rigidly mounted together on a shaft and the pulleys have a different number of teeth. A pair of belts are mounted on the drive shaft and a follower shaft, each one of the belts engages one of the transmission pulleys. One belt on the transmission shaft engages a pulley on the top of a first transmission pulley and another on the bottom of a second transmission pulley. When the drive shaft imparts motion to the belts, the belts move the transmission between the drive shaft and the follower shaft. By arresting the movement of one of the belts by a clutch/brake, the transmission can be converted into a two speed transmission. If the belts are independently driven, one each by two motors, the transmission becomes operable in an infinite number of pulley ratios. One particular application for this pulley transmission is in a carriage drive system for a Coordinate Measuring Machine.
    • 一种用于减小驱动轴和传动轴之间的滑轮比的变速器。 传动装置适于将较高速度的旋转运动转换成较低速度的直线运动。 变速器具有两个刚性地安装在轴上的滑轮,滑轮具有不同数量的齿。 一对皮带安装在驱动轴和从动轴上,每个皮带接合传动皮带轮之一。 传动轴上的一个皮带接合在第一传动滑轮的顶部上的皮带轮,另一个在第二传动皮带轮的底部上。 当驱动轴向皮带施加运动时,皮带将传动装置移动到驱动轴和从动轴之间。 通过用离合器/制动器阻止其中一个皮带的运动,变速器可以转换成两速变速器。 如果皮带独立地被驱动,则每个由两个马达驱动,变速器以无限数量的滑轮比可操作。 这种滑轮传动的一个特殊应用是用于坐标测量机的滑架驱动系统。
