主螺旋杆是螺旋压力机的关键零件之一。不仅要有高的传动效率,而且要有高的强度。为了满足主螺杆的传动效率,主螺杆一般都制成3～4头大导程螺纹的结构。螺纹的尾部,通常有一个空刀槽,以便于螺纹的加工,如图1所示。采用带有空刀槽结构的螺杆,虽然加工比较容易,但削弱了主螺杆的强度。为了保证主螺杆的强度,就必须加大主螺杆的直径。由于主螺杆尺寸的加大,其它有关零件的尺寸也要相应增大,机器的外形尺寸和重量都
The main screw rod is one of the key parts of the screw press. Not only must have high transmission efficiency, but also have high strength. In order to meet the drive efficiency of the main screw, the main screw is generally made of 3 to 4 large lead screw structure. The tail of the thread, usually with an empty sipe, in order to facilitate the processing of threads, as shown in Figure 1. The use of a screw with an empty slot structure, although the process easier, but weakened the strength of the main screw. In order to ensure the strength of the main screw, you must increase the diameter of the main screw. As the size of the main screw increases, the size of other related parts should also be increased accordingly, the overall dimensions and weight of the machine are
