群力机械厂机械加工车间全部车床都是陈旧的皮带车床,最高转速不过300转/分,生产率很低,往往出现完不成任务的现象。在这情况下,车间主任李太广积极动脑筋、想办法,并和工人一道研究,克服了许多困维,终于把旧皮带车床的平皮带传动改成三角皮带传动。使车头转速提高到750转/分。改装后的结构如附图所示。变速机构中的3个皮带轮跟空心轴的配合是转配合,并用两个厚1公厘的铜环把3个皮带轮隔开。3个皮带轮用铁环连成一体。工
Qunli Machinery Factory All the lathes in the machine shop are old belt lathes, but the maximum speed is 300rpm. The productivity is very low, so it is often the case that there is no task. Under such circumstances, the director of the workshop, Li Tai-wang, actively brains, thinks of ways, and studies with workers to overcome many difficulties and finally change the flat belt drive of the old belt lathe into a V-belt drive. The front speed increased to 750 rev / min. Modified structure as shown in the figure. The 3 pulleys in the variator are mated with the hollow shaft and the 3 pulleys are separated by two copper rings 1 mm thick. 3 pulleys with iron ring into one. work
