Involute meters in gears industry

novembre 08, 2023

Involute meters are vital tools in the gear industry, they were developed during 19th century, revolutionizing mechanical manufacturing through the standardization of the measurement of the geometric shape of gear teeth, known as"involute".

The involute is a curve generated by the rotary movement of two circles, one internal and one external, and represents the ideal shape of the gear teeth. Involute meters not only measure the involute itself, but also evaluate other essential characteristics, such as helix tilt, pitch errors, and deviations from the ideal shape. These precise measurements are critical to ensuring the proper functioning of gear mechanisms within machines.

Innovation in the gear industry

The involute, being the basis for the correct shape of gear teeth, has revolutionized the mechanical industry. Before the introduction of involute meters, gear manufacturing exhibited variations in tooth shapes and sizes, causing mating problems and inefficient transmission.

Even a slight deviation from the ideal shape could seriously compromise the operation of the machines. Involute meters were introduced to ensure uniform production and improve the reliability of mechanical transmissions.

Technological evolution and innovation

From manual and mechanical instruments, involute meters have followed a path of technological evolution, embracing computerized and automated devices. Today, these tools offer extraordinary precision and are widely used in industry to ensure the consistent quality of gear teeth and transmission systems.

Modern involute meters have achieved sophisticated levels of precision and control, allowing the measurement and control of a number of additional parameters beyond the basic characteristics of gear teeth.

In addition to the shape of the involute, modern involute meters are able to evaluate the entire topography of the tooth, ensuring compliance with pre-established parameters and the precision of the surfaces.

Measuring the roughness of toothed surfaces has become a crucial aspect. This check ensures that the surface finish is within specified limits to ensure optimal operation.

Using the Barkhausen principle, the involutimeter probe can identify and detect microfractures or cracks invisible to the naked eye, ensuring greater safety and durability in the use of the gear.

Modern involute meters can be connected directly to machine tools, establishing a closed loop. This connection allows real-time control of the machined piece. Any deviations detected by the involute meter can trigger direct changes to the machine tools, allowing instant corrections during the production process.
Future prospects and trends in gear control

The gear control sector is constantly evolving, with the introduction of increasingly sophisticated technologies. There is growing investment in the research and development of new sensors and advanced imaging systems, such as those based on laser technology adopted by companies such as Gleason. These innovations include high-precision laser sensors that enable detailed and rapid evaluation.
