TORQUE TRANSFER EFFICIENCY

___________________________________

 

The Tsudakoma dual lead gearing system features the largest tooth engagement of any rotary table manufacturer. This generates up to 85% torque transfer efficiency.

 

 

OVERSIZE WORM WHEEL

___________________________________

 

The Tsudakoma worm wheel uses an oversize diameter pitch circle resulting in reduced pressure on the contact surface compared to a conventional gearing system.

 

 

CROSS ROLLER BEARINGS

___________________________________

 

All Tsudakoma rotary tables and indexers use ultra precision cross roller bearings. Four times more rigid than angular contact bearings. 

GEARING MATERIALS

___________________________________

 

Tsudakoma uses proprietary high tensile strength brass to build the gears. This enables exceptionally smooth cutting due to the inherent lubricating properties. 

 

 

TOOTH PROFILE

___________________________________

 

Tsudakoma utilizes full depth engagement with a larger gear module resulting in a larger surface area yielding a substantially stronger worm gear system.
