Custom Helical Gear for Compact Gearboxes

Product Description

Laiwei manufactures custom helical gears for compact gearboxes and mechanical drive assemblies. Each gear is produced according to the customer’s drawing, CAD model or approved sample. Tooth geometry, bore and mounting features can be specified for the available gearbox space and the intended mating gear.

A helical gear cannot be selected by outside diameter alone. The module, number of teeth, pressure angle, helix angle and helix direction must work with the mating gear and shaft arrangement. Helical gears also generate axial thrust during operation, which the gearbox bearings and housing must accommodate. Material, heat treatment and inspection requirements are confirmed after the complete design is reviewed.

Custom Specification Guide

Key Selling Points

• Custom tooth and mounting geometry for space-limited gearbox assemblies.

• Gear and shaft interfaces can be reviewed together for correct fit.

• Drawing-based manufacturing provides a clear basis for inspection and repeat orders.

Applications

Compact motor gearboxes, mechanical transmission units and OEM drive assemblies that use parallel-shaft helical gears.
