2 We measure quality in micron

The WGT series from Liebherr ---

The measuring instruments of the WGT series have four extremely accurate axes, driven by smart and user-friendly software. They meet all accuracy requirements regarding gear manufacturing and comply with VDI guideline VDI/VDE 2612/2613, group 1. In addition to our standard measuring instruments, we also offer individual solutions, for example if you require an extended travel path in the Z-axis, longer tailstocks to mount long shafts, rotary tables adapted to the load capacity, or other specific adaptations.

An automatic probe changing system guarantees uninter-rupted measurement, even of complex workpieces, and also provides optimum user convenience. The extensive software features enable easy measurement of all types of cylindrical gears, bevel gears, worms, worm gears, shafts and gear cutting tools, as well as rotationally sym-metrical parts such as shafts. It is also possible to certify the measuring instrument according to ISO 10360.

Highlights: – Highest precision provided by granite guides and air bearings – Low operating costs due to contactless guides and reliable probe heads, as well as inexpensive spare parts

– Flexible use for all types of gears – User-friendly interface and ergonomic design – Manufacturer neutral GDE interface for data import from other manufacturers and data transmission for automatic adjustment of production machines (“Open Connect” or “Closed Loop”) (Option)

– Calibration of devices accordingly to globally recognized standards (ISO 10360)

– Fast availability of measuring results – Combination of several measuring programs (also for different gear or work piece types) possible in one set up

– Collision protection by means of continuous real-time monitoring of the axes and probe system

Software solution for a range of applications ---

Liebherr’s software has been established on the gear measurement market for 30 years. It has a very simple operating structure, which can be used very flexibly for different measuring tasks. The portfolio now also com-prises the manufacturer neutral GDE interface for the exchange of geometric and measurement data for auto-mated correction of setting data on gear cutting machines (LHOpenConnect).

The Liebherr software LHInspect contains all the important basic functions

– The probe management module for managing probes, including fully automatic probe calibration

– The alignment module to determine the axis position and compensate for clamping errors up to 2 mm

– The gear measuring module for fully automatic measure-ment of involute spur and helical gears (external and internal)

Additional software modules to measure: – Splines and serrations – Form & positional tolerances of rotationally symmetrical parts

– Hobs – Shaper cutters – Shaving cutters – Coupling gears – Worms – Worm wheels – Bevel gears – Broaches – Gear racks – Rotors, cycloids and sprockets

Software modules for: – Calculation of topographic data for straight bevel gears

– Calculation of gear data for unknown gears – Scanning of the tooth root

Making one out of two: chamfer measurement integrated into gear measurement

We have refined our measurement software for gears and combined two steps into one: Chamfer measurement is now integrated into gear measurement. Automated determination of the evalua-tion ranges in the first step ensures process reliability and maximum precision of the measurement results. In addition, the simplified data input and clear representation of chamfer angle, chamfer width, chamfer depth and further results in the measuring protocol ensure usability.

Added value from data using LHOpenConnect ---

We provide comprehensive support in integrating our machine into your production environment. The aim is to transfer production and measurement data with the maximum degree of automation in order to eliminate errors – regardless of the manufacturer of the connected devices – while at the same time maximizing production speed and manufacturing quality.

Possible workflow using GDE1. LHGearTec as a programming system for work

preparation2. Load the workpiece/tool/clamping fixture into

the gear cutting machine and produce it3. Measure the workpiece on the measuring instrument

and store the evaluation by GDE as a PDF4. Transfer measured values to the gear cutting machine:

open and correct (correction values can be automatically suggested)

5. Corrective part and/or statistical process control in series production

When developing state-of-the-art gearboxes, high effi-ciency, low noise emissions and weight reduction with a long service life have the utmost priority. In addition, designs range from the very smallest gears with a module of 0.3 mm to large bevel gears for ship propulsion. Meas-uring these parts requires reliable and precise measuring

instruments. In addition, the software must enable simple and seamless documentation of the measuring results according to certified standards. This combination of hardware and software is optimally coordinated for your quality assurance.
