This standard is formulated on the basis of the original ZB J85 018-89 and the universal joint technology currently in use in China. The main differences between this standard and ZB J85 018 are as follows: - The structural type and applicable models are increased: This standard specifies three types of universal joint structural types, namely plate type, frame type and cylinder type. - This standard specifies the technical contents such as the external dimensions, interface dimensions and tolerances, performance parameters, technical requirements and inspection rules of the universal joint assembly to ensure the applicability, interchangeability and reliability of the product. These requirements are given quantitative values ​​as much as possible to be verified by test methods. - This standard does not make standard provisions for the parts of the universal joint assembly so that the means of realizing the technical requirements of the universal joint assembly specified in this standard can have the greatest degree of freedom in selection. - This standard adds Appendix A. This standard specifies the classification, technical requirements, inspection rules and marking, packaging, transportation and storage of universal joints for crawler bulldozers. This standard is applicable to crawler bulldozers, and other engineering machinery variants can refer to it.

This standard is based on the existing coupling technology approved in the past years and is limited to the universal joints of the support structure of the two specifications and models of the support structure. In recent years, through the introduction and digestion of foreign advanced technology as well as domestic research and development and improvement of old products, the universal joint family unique to the extension type lift has formed diversified products, specifications and matching numbers. This standard summarizes the current status and development of domestic front-end coupling products in the formulation, and is used for the production and use of the standard. The main differences between this standard and ZB185018 are: (1) structural type and applicable machine models; this standard specifies various universal joint structures, namely, standard, energy and commercial types, and can be applied to all more than 20 types of extension type lifts in China. The standard specifies the overall dimensions, interface dimensions and tolerances, performance, technical requirements and inspection rules of universal couplings to ensure the interchangeability and reliability of the products. This standard may be used to verify the value of the product. The standard does not specify the parts of the universal coupling assembly. In order to make the technical requirements of the universal coupling assembly specified in this standard be realized in the process of selection. The standard adds the dimensions and basic data of the universal coupling assembly. In order to provide a better supply and demand effect, this standard will replace the annex or annex of J8518-3 of this standard. This standard is proposed by the Ministry of Machinery and the Technical Committee of Standardization of Machinery. The drafting unit of this standard is: the Ministry of Machinery Industry, Otsu Second Independent Machinery Research Institute, Xinzhou City, "Coupling", Xinzhou City, "Upper Joint". The ten key points of this standard are completed by the following people: Lord Qiu, Yang Yuanming, and Zhu Lihui. This standard was first issued on September 1, 1995. 1 Scope
