标准摘要
[中文适用范围]： ISO 5673 的这一部分给出了农业用拖拉机和自走式机器的动力输出 (PTO) 驱动轴的形式和应用，并规定了机具动力输入连接 (PIC) 的尺寸和周围的间隙区域。 ）用于各种附件。 其目的是当机具和拖拉机具有兼容的功率水平时，确保 PTO 传动系统与机具和拖拉机上的相邻部件之间有适当的间隙。 它并非旨在作为传动系设计的完整指南，并且不包含例如有关防止传动系振动或确定扭矩限制装置尺寸的信息。 它不适用于具有高离地间隙的农具与拖拉机的组合，例如那些在未成熟的蔬菜作物或甘蔗中作业的农用拖拉机，也不适用于设计用于低离地间隙的农用拖拉机，例如用于割草或地面护理的农用拖拉机，这些拖拉机需要较低的离地间隙。 重心;由于其功能的原因，它也不适用于必然设计的非对称实现。 [外文原描述]： ISO 5673-2:2005 gives the forms and applications of (PTO) drive shafts for tractors and self-propelled machines used in agriculture, and specifies the dimensions for, and clearance zone around, the implement power-input connection (PIC) for a variety of attachments. Its intent is to ensure proper clearance between the PTO drive line and adjacent components on the implement and tractor when both implement and tractor have compatible power levels. It is not intended as a complete guide for drive-line design and does not, for example, contain information on preventing drive-line vibration or sizing a torque limiting device. It is not applicable to combinations of implements with tractors having high ground clearance, such as those working in standing vegetable crops or sugar cane, nor to agricultural tractors designed for low ground clearance, such as for lawn mowing or ground care, which require a low centre of gravity; neither is it applicable to implements non-symmetrical in design by necessity due to their function.
