Our main product line is the Hansen P4 range of standardized industrial gear units. Low noise and minimum weight are merely a few of its outstanding characteristics which have also been incorporated in the Hansen P4 range of single stage gear units and the Hansen M-Series range of functional drives. Our complete portfolio of products and total drive solutions is reflected in this detailed product brochure. Torsten Schultz Managing Director Business Unit Industry In the late 1940’s, any company producing industrial transmission drive systems was faced with a problem that at the time seemed insoluble. No company had succeeded in standardizing the production of gear units. Expensive, custom-made solutions – time-con- suming to produce, assemble and maintain – were the norm. David Hansen, however, was a born innovator, who tackled the problem through original think- ing based on scientifically researched concepts. The result, launched in 1950, was the Hansen Patent-I – a revolutionary new concept for the design and manufacture of standard gear units. As David Hansen himself was able to say with understandable pride: “The Hansen Patent-I speed reducer constitutes an original and complete answer to the problem of standardization, meeting the requirements of application selling, mass production, quality and competitive prices.“ c o n t i n u o u s Moving from customized to serial manufacture led to a number of important benefits: • Production costs were reduced. • Improved quality control procedures could be implemented. • The number of spare parts was reduced. • Delivery times were slashed. Gear units were never the same again as other manufacturers followed Hansen’s lead. Since then Hansen has consistently been at the forefront of transmission technology. H a n s e n Tr a n s m i s s i o n s , a h i s t o r y o f _g i n n o v a t i o n PRODUCTS ■ HANSEN PATENT-I Common gear sets allowed Hansen Patent-I gear units to be inter-related, as one size of gear unit determined the preceding and following sizes. This is expressed in the “law of centre distances“, a principle which is still applied today in the latest Hansen products. ■ HANSEN PATENT-II In 1970 the product line was re-evaluated to respond to changing market requirements and to take advantage of new technologies such as improved hardening and grinding techniques. Based on the Hansen Patent-I principles of standardization of housings and gearings, Hansen Patent-II established new standards with the concept of market adequacy of the torque scale. The launch of Hansen Patent-II confirmed Hansen’s position as the worldwide leader in transmission drive systems. ■ HANSEN POWERPLUS By 1980 Hansen took another step ahead of the competition. The objective was to incorpo- rate new technologies and achieve the highest performance and reliability in this area. Emphasis was placed on the introduction of new rigid housings, in line with the high stiffness requirements for load distribution and low noise behaviour.

A typical example of this approach is the use of variable centre distances in a given housing size. In “traditional“ designs, with fixed centre distan- ce and torque rating, the reduction ratio of a single stage gear unit has a major effect on the power rating. This means that for small reduc- tion ratios, very large powers can be transmit- ted, which may lead to thermal limitations. At the other end, for large ratios, gear casings become oversized for the tr。
