第二汽车厂从美国威尔逊(VERSON)全钢压力机制造公司引进了一台2200st闭式双点压力机,该压力机第一级传动采用了多V型同步三角皮带传动方式。鉴于这种皮带具有一系列优点,现简单介绍如下。设计重型锻压设备如大型机械压力机时,为使传动机构运行平稳,减少噪音和保证传动精度,多在第一级传动采用三角皮带传动。由于大型压力机采用的主电机功率高,往往要选择D型或E型截面的三角皮带多根(常需8～12根)组合使用。然而由于这种普通三角皮带制造精度不高、内周长的制造误差太大,三角形皮
The second automaker introduced a 2200st closed two-point press from VERSON All Steel Press Manufacturing, a V-type synchronous V-belt drive in the first stage of the press. In view of this belt has a series of advantages, are briefly introduced below. In the design of heavy forging equipment such as large mechanical presses, in order to make the transmission mechanism run smoothly, reduce noise and ensure the transmission accuracy, more in the first stage transmission using V-belt drive. Due to the large main motor power used by presses, it is often necessary to select a combination of three or more V-belts (often 8 to 12). However, due to the manufacturing accuracy of this ordinary V-belt is not high, the manufacturing error of the inner circumference is too large,
