HERS GEAR DESIGN Do they have gear design and consulting services? Do they have full metallurgical laboratory for carrying out failure analysis? Are they members of any gear standard associations? (AGMA, DIN, ISO) GEAR INSPECTION Do they have certified gear inspection laboratory to inspect gear accuracy? Wind turbine gearing requires very high gear accuracy of DIN 3 or better. Can they provide computerised printouts of lead, involute and pitch? COORDINATE MEASURING MACHINE Do they have Coordinate Measuring Machine for checking bore alignment and size of gearbox housings? This is required for the planet carrier of the planetary stage on wind turbine gearboxes and components. MACHINING/FABRICATION Do they have gear manufacturing facilities for producing improved replacement gearing? Hofmann Engineering also fabricates and machines many of the wind turbine components. HEAT TREATMENT Do they have heat treatment facilities for replacement gearing, including qualified metallurgists? Carburising, induction hardening, nitriding, quench & tempering & stress relieving facilities? Gas carburising to 1,8mm dia for the output stage gearing for wind turbines. PRECISION GEAR GRINDING EXTERNAL & INTERNAL Do they have modern, climate controlled gear grinding facilities, capable of producing accurate gearing to DIN 2 (AGMA required to produce quiet running wind turbine gearing? ON-SITE MACHINING & INSPECTION Precision Portable Coordinate Measuring Machine for checking bore alignment and accuracy in situ. Portable line boring machine for re-machining worn gearbox housings in situ.GEARBOX BACK TO BACK LOAD TESTING Do they have gearbox testbed facility for load test running gearboxes? Hofmann Engineering has full gearbox load test facilities to 3,0kW. SITE INSTALLATION & SERVICE Do they have site crews trained in gearing to install and laser align gearboxes? Are they able to provide on-site machining services?
