    • A bolt tightening device includes bolt tightening mechanisms, a torque input unit, a toothed belt and torque transmission units. The torque transmission units are provided with toothed pulleys and are integrated with the bolt tightening mechanisms. A toothed pulley is fixed to the torque input unit, and drivably connected to all the toothed pulleys of the plural torque input units by the single toothed belt. Torque input to the torque input unit is transmitted to the bolt tightening mechanisms by the toothed belt, and used to simultaneously tighten, for example, seven bolts. Because, torque can be simultaneously transmitted to plural bolt tightening mechanisms using a single belt, the number of components is reduced and the size, weight and cost are reduced and ease of use is improved.
    • 螺栓紧固装置包括螺栓紧固机构,扭矩输入单元,齿形带和扭矩传递单元。 扭矩传递单元设有齿形皮带轮,并与螺栓紧固机构一体化。 齿轮被固定到扭矩输入单元,并且通过单个齿形带可驱动地连接到多个扭矩输入单元的所有齿轮。 扭矩输入单元的扭矩输入通过齿形带传递到螺栓紧固机构,并用于同时拧紧,例如七个螺栓。 因为可以使用单个带同时将扭矩传递到多个螺栓紧固机构,因此减少了部件的数量,并且减小了尺寸,重量和成本,并提高了使用的便利性。
