1Scope适用范围

This document specifiessafety requirements and their verification for the design andconstruction of power take-off (PTO) drive shafts and their guardslinking a tractor or self-propelled machinery to the first fixedbearing of recipient machinery. It describes methods for theelimination or reduction of risks that need specific requirementsincluding such risks arising from misuse, reasonably foreseeable bythe manufacturer. It is applicable only to those PTO drive shaftsand guards mechanically linked to the shaft by at least twobearings. When used with compatible guards for power take-off (PTO)of the tractor (master shield) or self-propelled machine and thepower input connection (PIC) of the power receiving machine, therequirements for power take-off drive shafts arecomplete.

本文件规定了动力起飞(PTO)传动轴的设计和建造的安全要求及其验证，以及将拖拉机或自行式机械连接到接收机械的第一个固定轴承的防护装置。它描述了消除或减少需要特殊要求的风险的方法，包括制造商合理预见的因误用而产生的风险。它只适用于那些PTO驱动轴和保护装置机械连接到轴上的至少两个轴承。当与拖拉机(主盾)或自行机配套的动力起飞护罩(PTO)和动力接收机的动力输入连接(PIC)一起使用时，对动力起飞传动轴的要求就完备了。
