To obtain cycloid gears with good running qualities and high load capacity, extreme precision is required when manufacturing the gearings and the base body. The root circle of the gearing must be maintained within extremely tight tolerances of just a few micrometers. In addition, the reference surfaces must run extremely accurately with respect to the gearing. Owing to the principle, the reference surfaces are either a central bore or three star-shaped reference bores arranged in the base body, the socalled “cam bores”. Because the high accuracies cannot be adhered to with standard machine tools available on the market and typical machining sequences, the components are measured and paired according to their tolerance situation. This means high additional costs and tremendous logistical effort in production and assembly. With the VIPER 500 MFM, Klingelnberg has, for the first time, developed a machine that is capable of adhering to these tight tolerances for a number of applications. This allows for significant cost reductions.
Gear manufacturing today is not just limited to gear cutting machines. These days, machining centers are equally capable of manufacturing gears. With the TM 65, Klingelnberg is taking a fresh approach to complete machining of toothed gears using a method that relies on Klingelnberg’s Closed Loop system. Bevel gears designed with KIMoS (Klingelnberg Integrated Manufacturing of Spiral Bevel Gears) are manufactured true to design on the basis of a virtual twin, making technological knowhow for the automotive industry available for small-batch production.
