Present Situation and Improvement of Gear Processing Technology of Grinding Machine

The gears machined by the grinding machine have the advantages of low transmission noise, high transmission efficiency and long life. Grinding machine gear processing is considered to be an expensive gear processing method used in aviation and other high-tech fields, but now the efficiency of grinding machine gears has been improved, the performance of grinding wheels has also become better, and the high cost has been greatly reduced. Therefore, it has been widely used in automobile and motorcycle gear manufacturing and other mechanical processing, and has reached the degree of universal application. In fact, all first-class automotive gear suppliers have toothpaste machines to maintain competitiveness, and the automotive industry will become a growth market for hard tooth surface processing in the next 2-5 years. As the grinding machine gear processing can eliminate the deformation of heat treatment, many gear boxes use grinding gears to better control the vacancy and noise of transmission. The grinding machine gear processing technology is basically mature in the whole gear industry and is growing rapidly. So let's learn about the current situation of grinding machine gear processing technology and improvement in various aspects!

Grinding machine gear processing technology progress:

1. Airborne measurement

Many grinding machine gear machining is more accurate because it is equipped with an on-board measurement system. Because the machine is used for measurement, there is no need to remove the gear from the workbench and send it to other places for inspection, which can avoid the secondary installation error during rework. When processing, the gear is first analyzed by the airborne measurement system, and then the measured parameters are compared with the theoretical design parameters to find out the required correction amount, the control system collects these correction data, automatically adjusts the toothpaste processing state, and then brushes the teeth. And measurement.

2. Direct drive motor

In recent years, the use of compact direct drive motors on grinding wheel spindles and gear workpiece spindles is increasing. In order to avoid errors in the transmission chain, the spindle is translated. Therefore, the use of direct drive motors in the "grinding wheel repair-gear grinding" cycle, combined with good grinding wheel and multi-axis linkage control, can eliminate high-frequency errors and harmful vibrations of cutting ribs, biased strain geometry, gear use noise.

3. Automation

The term "automation" is increasingly used for toothpaste processing, especially process-based production, such as workpiece installation, tool replacement, and inventory classification synchronized with the workpiece process. Automation helps to eliminate machine idle time and reduce waiting time between processes.

Grinding machine gear processing is a kind of production equipment for grinding gears. Due to its specific gear geometry, grinding machine gear processing provides excellent meshing effect and stable operation. Compared with cutting gears, the equipment works quieter and the grinding wheel consumption is more uniform. In addition, gear grinders can manage larger loads and are useful in situations where large amounts of energy are required.

Gear grinders are generally classified into continuous grinders and profile grinders. In continuous generation grinding, a tool (grinding worm) having a tooth profile different from that of a gear is used to grind a workpiece and the grinding worm by moving relative to each other. On the other hand, in profile grinding, a workpiece is ground using a tool having the same profile as a gear.
