我厂在液压粗镗专机的设计中,油泵与电动机的传动采用了一种结构较简单的联轴器。如图示,两个半联轴器分别用键与轴联接,中间弹性板为带有夹布层的废旧平皮带,圆周开有六孔,分别套在半联轴器的三个销钉上,通过皮带来传递扭矩。这种联轴器的制造、装配和维修都简单、方便,尺寸紧凑,寿命长,取材容易。适用于小功率、高转速而无剧烈冲击处。但两半联轴器需压紧,不允许有轴向移动。
I plant in the design of hydraulic rough boring machine, pump and motor drive using a simple structure of the coupling. As shown in the figure, the two couplings are respectively connected by keys and shafts, the middle elastic plate is a waste flat belt with a cloth layer, six holes are arranged on the circumference, respectively sleeved on the three pins of the semi-coupling, Torque is transmitted through the belt. The coupling is easy to manufacture, assemble and maintain, compact in size, long in life and easy to draw. For low power, high speed without severe impact at. But the two couplings need to be compressed, does not allow axial movement.
