A method for the determination of the optimal polynomial functions for the conduction of machine-tool setting variations in pinion teeth finishing in order to reduce the transmission errors in spiral bevel gears is presented. Polynomial functions of order up to five are applied to conduct the variation of the cradle radial setting and of the cutting ratio in the process for pinion teeth generat...

Purpose. Development of a mathematical model heavy loaded gear transmission with self-aligning drive gear; evaluation the dynamic load on in alignment process. Methodology. The calculation schematic and equations relative motion are formed using methods rigid body dynamics. Analytical expressions for self-alignment time, collision velocity during factor obtained by integrating an ordinary diffe...

  This study aimed to design a bycatch reduction device (BRD) for shrimp beam trawl, which is manufactured by flexible materials to reduce bycatch for the gear in the South Sea of Korea. The model test was carried out to understand the shape of the gear in the water and to measure the variation of flow speed due to the BRD in a circulating water channel. Catches were compared between a shrimp b...

Tooth root crack is considered as one of the crucial causes of failure in the gearing system and it occurs at the tooth root due to an excessive bending stress developed in the root region. The modern power transmission gear drives demand high bending load capacity, increased contact load capacity, low weight, reduced noise and longer life. These subsequent conditions are satisfied by the aid o...

Compared with other gear transmissions travelling along meshing line, the motion of crown coupling is much more complex, which makes difficult for its tooth surface wear simulation. To reduce computational costs associated simulation misalignment angle, a quick multi-step discretization and parallelization model proposed. The combines finite element method based on self-compiled high-precision ...

T his study investigates the short-run and long-run impact of real exchange rate misalignment and volatility on Indonesian export to the US by exploiting the disaggregated data of export volume. The proxy of real exchange rate misalignment was obtained by estimating the fundamental equilibrium exchange rate (FEER) model, and the exchange rate volatility measured by employing the GARC...

The machine maintenance strategy is very important in manufacturing, mining, and other industries so an appropriate needed based on industrial operating conditions. In this paper, a Proactive presented, which requires the identification of vibrations, vibrations divided into two methods, there are time domain frequency domain. Identification usually done analyzing gears because much noise domai...
