Flexible Gauging For Gear Inspection

The electrification of conventional automotive powertrains and the development of new electric drive units is involves traditional gear manufacturing and subject to several challenges and requirements.

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 become greater than at present. Therefore, the need to build up knowledge and experience in the field of gear inspection is paramount..

The Marposs M62 Flex is one of the gear measuring instruments that Marposs is promoting to fit these requirements. It’s a standalone manual use bench gauge for the inspection of some the most traditional toothing parameters of gears: DOB (MdK), Root Diameter and Tip Diameter. It is provided with two multiple contact turrets that can hold up to six different contacts each, which gives the opportunity to measure different gears and different features with no need to mechanically retool the gauge.

The use of electric driven actuators makes M62 Flex a flexible system with highly precise tools and a robust design, M62 Flex is able to monitor the quality of a gear immediately after crucial machining operations such as hobbing, shaving and teeth grinding.

The system can be installed on the shop floor close to machining operations in order to have a quick feedback on the result of the machining operation and a suitable solution for Tier manufacturers that have to deal with a huge variety of gears; including those from several industries.

Gear Manufacturing Process Under Control

The benefit of having in place a very quick measuring instrument next to the machine prevents the accumulation of parts to be measured in the laboratory, often resulting in a not negligible waste of time. Further, the use of a soft-landing technology prevents the risk of damages and marks on not-hardened parts, traditionally a problem much felt by the sector.

M62 Flex has the ability to inspect multiple gears having external diameter within the range of 30 – 180 mm, both spur and helical gears, including gears with odd number of teeth.

The system is provided with a guided interface that drives the operator through the very few measuring steps. The operator just has to load the gear on the gauge and follow the instructions on the screen. Soft-land Technology allows the measuring groups to approach the surface of the teeth with a controlled low force while monitoring their position error. This is identified as the proper solution to avoid damages and marks on parts.
