Gears are an indispensable part of mechanical transmission and are widely used in machine tools, automobiles, machinery, and other fields. Gear machining is one of the important processes in gear manufacturing. The equipment and processes required for gear machining will be introduced below.
Gear Machining Equipment
Gear machining machine tools are the most basic equipment for gear machining, mainly including gear cutting machines, gear grinding machines, gear hobbing machines, and gear shaping machines.
Gear cutting machines are one of the most commonly used machine tools in gear machining, mainly used for cutting the tooth profile of gears. Gear grinding machines are mainly used for machining precision gears, such as those used in high-precision machine tools and aircraft. Gear hobbing machines are used to manufacture gear shafts, mainly by reversely stretching metal materials to form gear shafts. Gear shaping machines are machine tools that process rod-shaped metal materials into gears through multiple processes.
Gear Measuring Equipment
Gear measuring equipment mainly includes gear measuring instruments, CNC three-coordinate measuring instruments, and harmonic analyzers. It is mainly used to check the machining accuracy and surface quality of gears.
A gear measuring instrument is a device specifically used for gear measurement, used to check the accuracy, layout, and concentricity of gears. A CNC three-coordinate measuring instrument can accurately measure various parameters of gears, including tooth pitch, module, and tooth width. A harmonic analyzer can check the surface quality of gears, such as gear vibration and balance.
Auxiliary Equipment for Gear Machining
Auxiliary equipment for gear machining includes gear cutting fluids, fixtures, tools, and tool grinders, mainly used to assist in gear machining.
Gear cutting fluid is a lubricant and coolant used in gear machining, which can effectively reduce friction and heat during gear machining. Fixtures can effectively fix the gear material to ensure stable processing. Tools are the main tools for cutting gears, and different tools need to be selected according to different gear materials and processing requirements. A tool grinder is a device used to grind and sharpen tools.
Processes
Gear Machining Processes
Gear machining processes include turning, milling, and grinding, with turning being one of the most commonly used gear machining processes.
Turning is carried out using a lathe on a gear machining machine tool, mainly removing gear material from the whole to form the tooth profile. Milling is carried out using a milling machine, mainly cutting on the surface of the gear. Grinding is carried out using a grinding machine, mainly used for machining high-precision and high-requirement gears.
Gear Machining Technology
Gear machining technology includes CNC technology, hole-making technology, and adaptive machining technology, mainly to improve the machining accuracy and efficiency of gears.
CNC technology is a technology that has entered the digital age in gear machining, using computer programs to control machine tools to complete the machining process. Hole-making technology is for machining internal gears, and a hole can be opened between the tooth profile and the shaft to complete the machining of internal gears. Adaptive machining technology uses sensors to achieve adaptive control during gear machining, improving machining accuracy and efficiency.
In summary, the equipment and processes required for gear machining are very rich, including gear machining machine tools, gear measuring equipment, and auxiliary equipment for gear machining. At the same time, gear machining technology is constantly developing and innovating, improving machining efficiency and accuracy, allowing gears to play an even more important role in mechanical transmission.
