摘要： A saw apparatus having a saw body with a front portion and a rear portion and two motors position on the body. A circular saw blade is mounted on each of said motors. The saw blades are oriented such that (i) a circumferential perimeter of the saw blades are in substantially the same plane; and (ii) a center of a first saw blade is positioned closer to the front portion of the saw body than is the center of a second saw blade.

摘要： A power tong unit having a gear train in which one or more of the gears in the gear train have removable and replacement roller tooth elements, in lieu of conventional gear teeth. In one embodiment, the ring gear and pinion gears have roller tooth elements, and idler gears disposed between the ring gear and pinion gears, have a semi-circular tooth root profile to mesh with the roller element gear teeth. The ring gear of the power tong unit may also have a removable section. A means for removing the removable section from the ring gear, and moving it to a position in which a tubular can be inserted into a central opening in the ring gear, may include a hydraulic cylinder, a clamping mechanism, and a cam surface to generate rotation of the removable section once lifted out of engagement with the ring gear.
摘要翻译：具有齿轮系的动力钳单元，其中齿轮系中的一个或多个齿轮具有可移除和替换的滚子齿元件，代替常规的齿轮齿。在一个实施例中，环形齿轮和小齿轮具有滚子齿元件和设置在齿圈与小齿轮之间的空转齿轮，具有与滚子元件齿轮齿啮合的半圆形齿根轮廓。动力钳单元的齿圈也可以具有可移除部分。用于从环形齿轮移除可拆卸部分并将其移动到管状件能够插入到齿圈中的中心开口的位置的装置可以包括液压缸，夹紧机构和凸轮表面，以产生可拆卸部分的旋转一旦被提升离开与环形齿轮的接合。
