TH Series

Harmonic Roatry Table – THE CHEAP SOLUTION

TH145-75

TH series is a CNC rotary table driven by Harmonic Drive gear, which is popularly used as a convenient positioning unit or as a fourth axis in CNC machine tools. For example, it can be installed parallel to the X-axis, Y-axis or Z-axis of the machine tool to add a rotary axis to the machine. Siemens and Bosch-Rexroth are available as drives. The TH series can be used as a dividing head or for continuous movements, enabling the machining of complex curved surfaces and extending the machining range.

TH145-75 Highlights

  • High load capacity. Harmonicdrive transmission. Together with the number of teeth engaged at the same time, the load capacity is higher than other transmission methods. Smooth transmission, no vibrations.
  • The Harmonicdrive reduction gear consists of a shaft generator, a shaft gear and a spur gear, where the shaft gear is a flexible, thin-walled, elastic part with an outer ring gear that continuously deforms during ring transmission. This eliminates backlash when interacting with the spur gear and achieves high precision and low transmission backlash.
  • Large gear ratio. The single stage reduction ratio can reach 80-100, so you can get a large output torque.
  • Pre-installed brakes with optional powerful brakes for heavy duty machining.
  • Smooth transmission, low effort, no noise.

Harmonicdrive

The internal drive is a simulated engagement of multiple teeth in a symmetrical position of 180 degrees, so that the gear pitch error and the cumulative tooth pitch error have a more uniform effect on the drive accuracy and a very high positioning accuracy can be achieved.

 

Size

Small sizes and low weight compared to conventional gearboxes. The significant reduction in sizes and weight allows for a very small design. As a result, the Harmonic axis saves space on the machine and reduces the load on the table.

Gear ratio

The single-stage gear ratio can reach 80-100, so you can achieve a large output torque.
