Introduction
1. Background and significance of the standard
This standard is under the jurisdiction of the National Technical Committee for Standardization of Rolling Bearings, and the drafting units include many well-known companies, ensuring its authority and practicality. This standard aims to improve the quality and technical level of precision bearings used in industrial robot RV reducers and adapt to the rapid development needs of the industry.
2. Overview of the main contents of the standard
| Chapter | Main content |
|---|---|
| Scope (Chapter 1) | Specifies the classification, code method and applicable scope of precision bearings. |
| Terms and definitions (Chapter 3) | Clarifies the definitions of key terms such as RV reducer and main bearing. |
| Code method (Chapter 6) | Includes prefix code, basic code and suffix code, such as 'RVB76/66AJ/P4'. |
3. Key technical requirements
Material and heat treatment: Rings and rolling elements are made of high-grade high-quality GCr15 steel, and the heat treatment quality meets the requirements of GB/T34891.
Tolerance and clearance: The assembly height deviation of the main bearing and unit has strict requirements (Table 3), and the radial clearance of deep groove ball bearings meets the requirements of Group N in GB/T4604.1.
4. Implementation suggestions
Case analysis: Correct selection and maintenance
When selecting bearings, the model should be determined according to the torque and structure type (E/C series) of the RV reducer. Check the lubrication condition regularly to ensure that the friction torque meets the requirements.
