Hydraulic Coupling Gear Indexer
- HIGH ACCURACY
- --Dual Lead Worm Gear System--
Three Pieces of Hirth Coupling Gear is built inside positioning and indexing, keeping high accuracy even after long term using. The index accuracy is within ±4 arc sec. and Repetitive accuracy ±1.
- HEAVY DUTY CUTTING TOLERATION
- --Three Pieces of Hirth Coupling Gear clamping system--
With Three Pieces of Hirth Coupling Gear built inside, there is no floating action during degree indexing, and whole-closed structure design can keep dust and cutting fluid out from the body even if much cutting fluid is used. High rigidity and gripping force increase the efficiency greatly during heavy duty cutting.
- HIGH STABILITY AND SAFETY
- --Clamp/ Unclamp sensor--
Driving by hydraulic unit, clamp/unclamp sensor which execute unclamping, rotating, clamping and returning ensures stable and safe operation. It’s suitable for special purpose machine indexing and automatic changer.
- DIRECTION
- --Structure of Three Pieces of Hirth Coupling Gear--
Refer to the figure below. The Structure of Three Pieces of Hirth Coupling Gear is divided into three parts: Gear plate A (locked on the rotation plate); Gear plate B (locked and fixed to index table bottom); Gear plate C (up and down action board)
- Refer to figure b. When Hirth Coupling Gear C descends, the index table is unclamping. As Gear plate A is supported, the rotation plate rotates smoothly and accurately without vertical moving error.
- When Gear plate A completes indexing, Gear plate C goes up to match Gear plate A and B, clamping the index table.
- Gear plate C has sufficient space to completely match Gear plate A and B. The pressure angle of 30 degree of each gear focuses Gear plate A and B accurately, keeping high accuracy even after long term using.
