The accuracy of the parts of critical components for wind turbines determines the efficiency of the system. Carl Zeiss supports the rising quality requirements for components for wind turbines with highly precise MMZ 3D coordinate measuring machines.
A wind turbine is designed to convert wind into electrical energy with maximum effectiveness throughout its entire lifecycle. This requires reliable compliance with size, form and position tolerances during production of the moveable parts. This applies primarily to the pinion cages and housings of planetary gears. The axis spacing must fit perfectly; the axis alignment must be absolutely parallel. Only then can good operating characteristics be achieved with a high level of effectiveness.
MMZ measuring machines: all-rounders for the measurement of large parts
MMZ gantry measuring machines quickly deliver reproducible measuring results as the measuring machines and software are optimally matched. They are used in production and measuring labs to measure and document machined prismatic and round parts, as well as freeform surfaces. The MMZ T machines feature an integrated measuring table; the MMZ G line receives parts at ground level and with clamping plates. Loading systems considerably reduce downtimes.
Together with CAD-based CALYPSO® measuring software, VAST technology from Carl Zeiss optimizes measuring processes. It can deliver form, size and position information, and can determine the roundness of parts in a single measuring run. The performance of VAST navigator during the form measurement of parts with deep-laying features is practically unparalleled. The highly accurate VAST® gold active scanning probe permits the use of extensions up to 1000 mm, enabling measurement of deep-lying geometric elements. Therefore, this scanning technology is ideal for complex part geometries and automated CNC measuring runs. If features have to be inspected in different orientations and positions, the RDS articulating probe holder further increases measuring efficiency. RDS enables more than 20,000 stylus positions at 2.5 degree increments for the VAST XXT scanning probe (with styli up to 250 mm) and also for the LineScan® optical laser triangulation sensor. LineScan on RDS is well-suited for the fast acquisition and form inspection of freeform surfaces using HOLOS® NT software.
Each MMZ gantry measuring machine, such as the MMZ G200 with linear measuring tolerance of 2.8 + L/400 micrometers, features the required accuracy. Carl Zeiss offers the MMZ G with measuring volumes of up to 4,000 x 8,000 x 4,000 mm, and thus corresponds to the trend towards ever larger parts. Equipped with a rotary table, it is possible to measure cylindrical parts and gear wheels, including the full mathematical compensation for eccentricity and wobbling movement. Rotary tables with a diameter of up to 2000 mm and a load capacity of up to eight tons are optionally available. GEAR® PRO software permits measurement of gears without a rotary table.
Measuring technology from Carl Zeiss at Mechanical Drives
Siemens Mechanical Drives is one of the leading providers of systems and components for mechanical drive technology in the middle and high torque range. Headquartered in Bocholt, Germany, the corporate unit manufactures complex large parts such as large housings and pinion cages for wind turbines, for example. This requires extremely reliable measuring technology for quality assurance in order to improve the production processes and thus guarantee the quality of the parts. Frank Howestädt, responsible for quality assurance measuring technology at Mechanical Drives emphasizes: "We rely on the best quality in production to ensure the service life of our products. Production therefore directly depends on the measuring technology. This is the only means of ensuring production process and part quality. The MMZ measuring machines from Carl Zeiss fully meet our special demands for the construction of wind turbines.” Additional MMZ gantry measuring machines from Carl Zeiss are also used in the production environments for the measurement of size, form and position at the various locations of Mechanical Drives around the globe.
