Foreword

This standard is for GB/T 9877.1-1988, GB/T 9877.2-1988 and GB/T 9877.3-1988 "Rotating Shaft Lip Seal Consolidation revision of the "Ring Structure Dimension Series". Compared with GB/T 9877.1-1988, GB/T 9877.2-1988 and GB/T 9877.3-1988, the main changes of this standard are as follows. ---The name of the standard was changed to "Code for Design of Lip Seal Rings for Hydraulic Transmission Rotary Shafts"; ---Combine the standard structure from 3 parts into a whole; ---The technical content of structural design has been greatly revised, focusing on design guidance, supplementing technical content such as "return oil seal design", and The standard structure and arrangement order have undergone major changes. Appendix A and Appendix B of this standard are informative appendices. This standard was proposed by China Machinery Industry Federation. This standard is under the jurisdiction of the National Hydraulic and Pneumatic Standardization Technical Committee (SAC/TC3). Drafting organizations of this standard.
