What are the manufacturing requirements and implementation standards for drum gear couplings?Here is a brief summary for everyone.Specific industry standards need to be inquired separately.
1、鼓形齿联轴器的内齿圈,外齿轴套的材料均采用42CrMo,半联轴器的材料采用45锻钢或ZG310-570,这些材料的化学成分和力学性能应符合JB/T6396-1992,JB/T6397-1992和GB/T11352-1998等标准的规定。
2. The outer gear sleeve and the inner gear ring should be heat treated, and the heat treatment requirements have corresponding reference tables
3、铸、锻件的质量要求有相关规定JB/T5000.6-1998和JB/T5000.8-1998标准
4. The strength grade of flange bolts of drum-shaped gear coupling is in accordance with the 3098.1 grade specified in GB/T2000-10.9.
5. The outer gear sleeve, inner gear ring and half coupling shall be subjected to non-destructive inspection according to the drawing requirements.
7、内齿、外齿精度等级按GB/T10095-2001规定的8级,啮合面的表面粗糙度Ra不得大于3.2um。
8. The deviation of the amount of bulge at the root of the outer gear sleeve of the drum-shaped tooth is in accordance with the JS7 level regulations
9、半联轴器和外齿轴套空的加工精度为H7,其表面粗糙度Ra不得大于1.6um,圆柱轴孔的圆柱度不得低于GB/T1184-1996中规定的8级精度。
10. The type and size of the shaft hole and keyway of the drum gear coupling are in accordance with the regulations in GB/T3852-1997
11. The position tolerance of the joint reaming hole of the internal gear ring to the nominal position should be less than half of its fit tolerance.
12. The symmetry of the central section of the tooth width of the outer gear sleeve is ±1mm. 13. The inner and outer gears of the coupling are engaged in an oil bath to prevent oil leakage. Grease is generally used
The above is the production standard of drum gear coupling.
