Abstract

Bending parts are widely used in the industry like buildings, bridges and train rail. Bending technique is an important indicator which can evaluate the development level of national industry. Dissymmetric structural steel bending process has problems such as thickness imbalance and partial damage. In this paper, in order to overcome the problems of dissymmetric structural steel bending process, a novel cold bending method for channel flage up was developed to replace the traditional induction heating bending process.

Key Words : Dissymmetric structural steel, cold bending, Mold

Abstract

Korea is the best country for ship-building. But nowadays, the speedboat and yacht are not mostly developed yet. For the sleek lines of ship, more innovative transmission system should be obtained in the ship industry. In general, marine transmissions often use the straight shafts and the helical gears. So it makes problem that engine-room requires large space. In this case, conical gear is the best solution for this.

Conical involute gear, or beveloid gear is very useful in machine design part. But it had not been using until several years ago, because there are some weak points, such as point contact phenomenon of tooth bearing at crossed axes and skewed axes except for parallel axes theoretically, and limited tooth width in terms of addendum modification coefficient which change along the axis of gear.

However, conical involute gear is rising as new gear technology. AUDI has already used conical gear in passenger's car gearbox which is called S-tronic to transfer power from transmission's output shaft to front axle and ZF makes Down Angle Transmission for marine gearbox. They not only show conical involute gear can be applied to commercial gearbox recently, but also know that conical gear is very useful and has many attractive applications.

In conclusion, until now, this technology is not generalized, but it will be increased more through many applications. So, in order to get conical gear design technology by ourselves, this thesis is conducted.

As preciously stated, this paper was written to gain useful information of marine gearbox design applied conical gear through the measurement of backlash, computer analysis and tooth contact test of helical conical involute gear pairs.

Keywords: Involute, Conical Gear, Marine Gearbox, Backlash
