How does a gear rubbing machine ensure the accuracy and surface quality of gears?

Gear rubbing machines rely on a combination of precision design and technology to ensure the accuracy and surface quality of gears. Its main purpose is to produce gears that meet high standards through efficient and stable processing. The precision control and surface quality optimization of gear rubbing machines involve technical measures in many aspects.
The precision control of gear rubbing machines is first reflected in their mechanical structure design. Precise machine rigidity, stable feed system and high-precision transmission system ensure the position accuracy during gear processing. Through fine mechanical assembly, the gear rubbing machine can eliminate any possible deformation factors during the processing and ensure consistency at every stage of the processing. This stable mechanical structure enables each tooth shape and size of the gear to be accurately presented, thereby ensuring that the key parameters of the gear such as pitch, tooth width and tooth height are within the required range.
The gear rubbing machine uses precision cutting tools in the processing process. The materials and manufacturing processes of these tools determine the accuracy and surface quality of the gear. High-quality cutting tools can not only effectively improve processing efficiency, but also ensure the processing quality of the gear tooth surface. During the cutting process, the sharpness and hardness of the cutting tool directly affect the realization of the smoothness of the gear surface, avoiding tooth surface defects caused by tool wear during the processing process.
During the operation of the gear rubbing machine, precise measuring and detection equipment will be used to monitor the status of gear processing in real time. These devices can accurately measure the dimensions in the process and adjust the processing parameters according to real-time feedback. For example, during the rolling process, the contact angle between the tool and the workpiece, the cutting speed and the feed rate will be fine-tuned according to the measurement results to ensure that each gear meets the design requirements during the processing.
In order to further improve the surface quality of the gear, the gear rubbing machine usually uses a special lubrication system during the processing. Appropriate lubrication can not only reduce friction during the cutting process, but also effectively reduce thermal deformation and wear on the gear surface. This helps to improve the finish of the gear surface, reduce surface roughness, prevent defects such as cracks and peeling, thereby ensuring that the gear surface is smoother and has a longer service life.
During the processing process, the vibration and temperature control of the gear are also important factors to ensure accuracy and surface quality. The gear rubbing machine can effectively reduce the vibration generated during the processing through a reasonably designed shock absorption system, which helps to maintain processing stability and prevent dimensional fluctuations or surface unevenness caused by vibration. In terms of temperature control, the equipment is usually equipped with an efficient cooling system to ensure that the gears and tools maintain a suitable temperature during the processing process to avoid thermal deformation caused by high temperature affecting the accuracy and surface quality of the gears.
