CAVEX worm and wheel sets with concave profile – according to modular design with a progressive ratio in sizes.

A specialty are DUPLEX worm and wheel sets which allow an adjustment of the circumferential backlash to a minimum.

The gear sets are designed and optimized taking into account the ruling parameters for the respective application using electronic design programs.

Advantages

In addition to the general advantages of worm gears sets, as:

• large transmission ratio in one gear stage
• irreversibility possible when at rest
• damping of vibrations, low-noise level and insensitive against shocks

CAVEX-worm gear sets have following special advantages:

• better lubrication and sliding conditions by the CAVEX teeth geometry
• smaller Hertzian pressure of the CAVEX gearing compared to conventional tooth form
• higher efficiency
• bigger tooth root thickness and safety of the CAVEX gearing

Optional design

• rough-turned or finish-machined worm shafts according to customer drawing
• right- or left-hand gearing
• reduced backlash
• increased accuracies
• DUPLEX® gearing (backlash adjustment)
