Compound \/ double spur gear<\/h2>\n

A double spur gear combines two tooth sections on a common component, often to create a compact compound reduction. Both meshes and the shared bore or shaft interface must be controlled together.<\/p>\n

Compound gears often place a small and large gear section close together. This can create thick hub regions or thin webs depending on the ratio. The axial relationship between sections should be treated as a functional dimension because each section meshes with a different shaft in the assembly.<\/p>\n<\/section>\n

How to read the product photograph<\/h2>\n

The main image is a photograph of a physical sample or representative component, not a dimensional definition. Resin colour, tooth count, bore or hub features, rack length, inserts and other details can change with the released drawing. Use the photograph to understand the product family; use the controlled drawing, mating interface and agreed inspection plan to manufacture and approve the part.<\/p>\n<\/section>\n
