As one of the main products produced by the manufacturer, WG drum gear coupling is required to be manufactured according to the corresponding production requirements and implementation standards. Although the model can be customized, the production standards of each coupling are inconvenient. The following is a brief summary. Specific industry standards need to be checked separately.

1, WG type drum gear coupling inner ring, outer gear sleeve material are 42CrMo, half coupling material is 45 forged steel or ZG310-570, the chemical composition and mechanical properties of these materials should be in line with JB/T6396-1992, JB/T6397-1992 and GB/T11352-1998 and other standards.

2, the outer gear sleeve and the inner gear ring should be heat treated, heat treatment requirements have the corresponding reference table.

3, casting, forging quality requirements have the relevant provisions JB/T5000.6-1998 and JB/T5000.8-1998 standards.

4. WG type drum gear coupling flange bolt strength grade is 10.9 according to GB/T3098.1-2000.

5, the outer gear sleeve, the inner gear ring and the half coupling according to the design requirements for non-destructive testing.

6. The cylindrical surface of the inner gear ring and the top of the outer gear sleeve of the drum gear coupling are spherical centering, and the match is H9/h7.

7. Accuracy of inner teeth and outer teeth shall be graded 8 according to GB/T10095-2001, and surface roughness Ra of meshing surface shall not be greater than 3.2um.

8, drum tooth outer tooth sleeve root bulge deviation according to JS7 level.

9. The machining accuracy of the half coupling and the outer gear sleeve is H7, the surface roughness Ra shall not be greater than 1.6um, and the cylindricity of the cylindrical shaft hole shall not be lower than the 8 class accuracy stipulated in GB/T1184-1996.

10. The type and size of shaft hole and keyway of drum gear coupling shall be specified in GB/T3852-1997.

11. The position tolerance of the link reaming hole of the inner gear ring should be less than half of its matching tolerance.

12, the symmetry of the center section of the outer tooth sleeve tooth width is ±1mm 13, the inner and outer teeth of the coupling work in the oil bath, there shall be no oil leakage phenomenon, the general situation is grease.

The above is the standard reference for the production of WG drum gear coupling, and I hope to help customers who want to know this knowledge. The machinery manufacturers also design and produce clamp coupling, flange coupling, diaphragm coupling, tire coupling and other products, welcome your consultation and visit.
