Oden product overview - Oden Control AB - #4

Oden Control AB (publ) was estab­lished in 1996 by Gustav Rennerfelt, a Swedish inventor, who has been designing and engineering special application gearboxes since 1980.

The company was founded on the principle of providing customers' special needs based on the innova­tive Oden Gear Systems™ (protected by several patents). Early in 2001 the company went public, and the shares are traded on the official trading mar­ket Aktietorget in Sweden with some 300 private shareholders.

The products, based on the Oden Gear Systems™, provide new solu­tions to'customers in many different types ofindustries.Thousands of solutions have been delievered in Europe and overseas for a number of different applications. These include heavy duty industrial applications.

This unique patented gear system, which comprisesjust two gears and an eccentric, has been designed using advanced CAD modeling and computer calculations.

The input shaft to the gear system has an eccentric tap with a ball bearing and an inner gear meshing a stationary internal gear. When the input shaft is rotated one turn, the innergear rotates onetooth pitch in theopposite direction ifthedifference in amountofteeth is one.This gives an exceptionally high gear ratio in one step with as much as 5 to lOteeth in meshing.

100 teeth at the inner gearand 101 teeth atthe stationary internal gear results in a reduction ratio of100:1 in one step.

To transmit the slow eccentric rotation ofthe innergear to a centric rotation on the output shaft, some kind ofcoupling must be used.The Oden Systems™ gear utilizes a simpleand reliable solution:

The inner gear consists ofa cylindrical "pipe" with a slightly conical gear placed at one end, and in the other end an internal gear working as a coupling.

The inner gearthus makes a conical movement around the centre point ofthecou-pling. Withveryfewpartsyougeta high reduction ratio,stiffnessand silent running.

This simple design creates a compact, lightweight and reliable speed reduction system with extremely high accuracy and low maintenance.

The total gear efficiency is higher than 90% and the one-step gear up to 250:1 gives a very compact design. The Oden Gear Systems™ is protected by patents worldwide.

The Oden Gear Systems™ is used in applications which require high reduction ratios with perfect accuracy and reliability as in turning/linear actuators, robotics, high performance electronic instruments and high torque industrial applications.
