- Gleason Corporation
Gleason Corporation (formerly Gleason Works) is a prominent
machine toolcompany based in Rochester, New York, USA. It has manufacturing plants in the USA, Britain, India, and Germany, and sales offices in those and additional countries.
Gleason's importance lies in
gearmanufacturing—specifically, in building the machine tools that themselves make gears. These gears and these machines are sold to industrial customers in a wide variety of fields, including prominent companies in the automotiveand aerospaceindustries. Gleason pioneered mass production of automotive spiral bevel gears in the US after settling an infringement law suit with Packard, the original inventor, patents US725328 and US1209682 of we call today Gleason spiral bevel gears US patent 1325784. However, more productive and less expensive manufacturing process for manufacturing of spiral bevel gears has been used in Germany. In the result of the World War II, Gleason received an advantage versus German competitor and established its gear influence in Europe. While Gleason spiral bevel gears are offered in Europe, the native for European market Klingelnberg and Oerlikon gears are more popular and offer better benefits in mass production for European automotive industry. It is not a secret that fuel economy of European cars is better compare the cars produced in the US, partially thanks to use of spiral bevel gears on drive axles as an alternative to lower efficiency hypoid gears that are commonly used on US cars and trucks.
