- Increased simultaneous interlocking
Number of teeth interlocking at a time may be more than tripled as compared with a cylindrical worm reducer
- Improvement in Contact-line position
A contact-line position or a contact area can be improved by way of changing an inclination angle of a worm tooth
- Reduced Size & Weight
Size of wheel may be made smaller by about 30% as compared with a cylindrical worm gear, resulting in considerable reduction also in weight
- Grindability
The teeth surfaces both of a worm and a worm wheel may be ground
- Reduction in Pressure on Unit Surface
As explained on the above, pressure on a unit surface is decreased, resulting in reduction of temperature and wearing
- Requires no Correction
In conventional Double Enveloping Worm gears including both Hindly type and Lorentz type, correction is required to obtain a proper contact area, while in PHIT worm gears, a proper contact area is obtainable without correction Further, a PHIT worm gear has an adequate entrance clearence, resulting in high realibility against burn
- Durable bearing
Ball and roller bearing are used in our standard models and they are designed to be sufficiently strong in meeting any demands by our customers. Special considerations are also given to a sealing device to protect bearings from dusts or any other foreign materials.
