Description
33
сительно поршн 3, а поршень 2 во врем работы вообще не враш,ает€ .piston 3, and piston 2 doesn’t vrash at all during operation, € is.
Так как гайка 4 и внЗтренн часть храпового устройства 5 имеют малый момент инерции , то силы, возникающие в геликоидальной паре, будут небольшими. Это уменьшает износ геликоидальной пары и повышает КПД новоротного механизма.Since the nut 4 and the internal part of the ratchet device 5 have a small moment of inertia, the forces arising in the helicoidal pair will be small. This reduces the wear of the helicoidal pair and increases the efficiency of the rotary mechanism.
