Double Enveloping Worm Gear

  1. Cone Drive Double-Enveloping Worm Gear Technology In 1925, Samuel L. Cone developed a method to machine the double-enveloping worm gear. With Cone Drive’s double-enveloping technology, the worm ‘hugs’ the gear creating greater surface contact, higher load capacity, lower contact stress and greater shock capacity. This gives you the flexibility to decrease the size of a worm drive gearbox to save space or increase the motor to get more power.
  2. WORM GEARBOX EFFICIENCY WITH A POWERFUL DESIGNGreater surface area contact means the load is distributed across more teeth allowing the worm gear reducer to run cooler, quieter, and more efficiently. Cone Drive worm gear reducers are through hardened to further provide additional strength. An efficient design without sacrificing power means cost savings with no loss of performance.
  3. Service Factor Savings Cone Drive worm drive gearboxes allow you to maintain service factor levels in a smaller package. The ability to down size equates to space savings in your system and cost savings in your pocket. We publish ratings you can rely on, Cone Drive tests their ratings in accordance with the American Gear Manufacturers Association (AGMA) standards.
  4. Product Variety Cone Drive worm gearboxes cover a diverse spectrum of markets. We offer a wide range of hollow output bore options to accommodate even the largest of required diameters and small worm gears too. If you are looking for a solution to a gearing application, Cone Drive has the answer and the product range to back it up.
  5. Let’s Talk Bearings We use two heavy duty roller bearings to provide dual support for the worm. The additional support increases the longevity of the worm gearbox which means less down time. Heavy duty bearings are used on the output shafts, which is excellent for applications that require high overhung loads. This not only simplifies the design, but lowers your cost.
  6. WORM DRIVE GEARBOXES WITH POWER AND ACCURACYThe inherited accuracy of the double-enveloping gearing keeps the deflection and torsional displacement low which is exactly what you need for your most critical timing and indexing applications. For even further control, Cone Drive worm gears provide you with exact ratios eliminating the problems posed by fractional units. We offer solutions with standard, low, and zero backlash worm gearsets.
  7. Custom is Our Specialty Our experienced team of customer service representatives, application engineers, design engineers and manufacturing engineers are ready and willing to take on a challenge. Let us put our expertise to work and develop a solution customized to fit your needs. We can design and manufacture any type of worm drive gearbox application that you require.
