The electrification of conventional powertrains and the development of new electric drive units is also involving gear manufacturing. Electrified transmissions are subject to several challenges and requirements. Notably, the number of gear wheels is significantly reduced in electric vehicles due to the use of one or two-speed reducers instead of the classic manual or twin-clutch gearboxes. In return, the quality of these gears must surpass current standards. Therefore, the need to build up knowledge and experience in the field of gear inspection is more crucial than ever.
Marposs offers a very wide range of solutions and applications for gear inspection by relying on decades of experience in this field. By providing sensors for machine monitoring, off-the-shelf solutions, and complex customised applications, Marposs positions itself as the perfect partner to help keep the entire gear manufacturing process under control.
Marposs’ M62 Flex manual bench gauge system for the production floor provides the flexibility to measure gears with different diameters without mechanical retooling. Using a universal reference Vee on a 30° angle eliminates the need for an ID centering post (or nose piece) to locate each part for measuring and reduces setup time.
The gauge employs servo-driven actuators and integrates soft-touch technology when engaging with the gear being measured. Soft-touch technology addresses the issue where green parts and master parts could be damaged by the measuring contacts. The M62 soft-touch technology employs a software routine where the measuring group can approach a gear surface in velocity mode, with a controlled low force, while the position error is monitored, resulting in better control of the process and avoiding damage.
The M62 Flex can inspect odd- or even-toothed helical and spur gears with external diameters from 30mm to 180mm, heights from 15mm to 40mm and from 1 to 4 modules. It has mechanical turrets with capacity to locate up to 12 contacts each and is suited for inspecting DOB (MdK), major diameter, and minor diameter.
