对重量较大的齿轮类零件,在加工中的吊装问题不可忽视。它关系到齿轮加工的质量、工人的劳动强度、工作效率和安全等。下面介绍两种简单实用的齿轮吊具。一、枪机式齿轮吊具外径1米多的回转齿圈(图1)是汽车吊的关键零件之一,单件重量约200公斤。加工这样的大齿圈,原来上下机床都用钢丝绳吊装。由于用钢丝绳吊装不易找平衡,不但吊装慢,而且不太安全,容易打滑,碰伤人,碰坏机床和工件。为此,我们设计制造了一种枪机式吊具(图2)。由于这
On the weight of gear parts, lifting in the processing of the problem can not be ignored. It is related to the quality of gear processing, worker labor intensity, work efficiency and safety. Here are two simple and practical gear spreader. First, the bolt-type gear spreader Outer diameter of more than 1 meter rotary ring (Figure 1) is one of the key parts of the car crane, a single weight of about 200 kg. Processing such a large gear ring, the original use of wire rope lifting the machine down. As the wire rope hoisting is not easy to find a balance, not only hoisting slow, but not too safe, easy to slippery, bumps people, touch machine and workpiece damage. To this end, we designed and manufactured a bolt-type spreader (Figure 2). Because of this
