Primary gear drive/secondary gear drive (also known as “Master Slave”)
In an industrial context, the primary gear drive/secondary gear drive system most often refers to control systems in which one device plays a master role and controls the operation of other devices. The primary gear drive is responsible for supervising work and making decisions, while the secondary gear drive executes commands issued by the primary gear device.
In DTI, we use the primary gear drive/secondary gear drive system, among others for backlash compensation. Backlash in the machine tool causes some delay or lack of precise synchronization between the drive and the tool or material. This leads to inaccuracies in the dimensions of the workpiece. Backlash can occur in both linear and rotary systems. Most often, it is the result of wear of mechanical elements, errors in calibration or simply in the design of a machine tool.
The use of the primary gear drive/secondary gear drive system for backlash compensation in machine tools brings many benefits:
Increasing machining precision – Thanks to dynamic backlash compensation in real time, the machine tool can maintain constant positioning accuracy, even when mechanical components are worn.
2. Increased machine durability – Prolonged operation of machine tools with backlash can lead to further wear of components. The primary gear drive/secondary gear drive system allows you to minimize the effects of this wear, which results in a longer lifetime of machine tool.
3. Increasing production efficiency – Precise “backlash” management translates into fewer production errors and greater stability of machining processes, which leads to higher machine tool efficiency.
4. Cost reduction – Thanks to the compensation of backlashes, there is no need for constant servicing and replacement of worn elements, which reduces the maintenance costs of the machine tool.
