Engineering note:<\/strong> Worm hand describes the direction of the helix. It affects how the pair is arranged and how rotation translates through the mesh.<\/p>\n

\"Right-Hand
Selection media for the relevant worm or wheel family. Final production geometry is confirmed from the RFQ.<\/figcaption><\/figure>\n

What changes mechanically<\/h2>\n

A replacement worm with the wrong hand will not be interchangeable even if module and size appear similar.<\/p>\n

Small worm gearing is sensitive to the relationship between the two members. Module or nominal size is only one coordinate. The mating definition also includes starts, hand, ratio, center distance, tooth system, material pairing and the way both components are located by bearings or hubs.<\/p>\n

How to select or specify it<\/h2>\n

Mark hand on the drawing and include an assembly view with input and output rotation arrows. That removes ambiguity caused by viewing the part from opposite ends.<\/p>\n

For a useful technical review, add the operating conditions: input speed, expected output torque, duty cycle, reversing frequency, ambient temperature and lubrication method. These inputs help separate a geometry question from a material, wear or thermal question.<\/p>\n

What to verify before release<\/h2>\n

For reverse engineering, photograph the original worm from a consistent datum side and record the direction of rotation in service.<\/p>\n
