Abstract

Screw conveyor is a material transfer equipment that is often used in various types of industries. However, the screw conveyor also has some disadvantages if it used in the blasting room serves to transport the steel grit which is the main material in the blasting process. This screw conveyor often suffers damage to the pillow block due to the inclusion of steel grit. Based on field conditions, the screw conveyor transport capacity is considered inefficient because some of the steel grit left in the gap between the screw and the curved steel plate and not get transported by screw conveyor. In order to overcome the problems, a belt conveyor is chosen to replace the screw conveyor. The method used in this final project firstly is identifying the problem of the existing screw conveyor and observing the screw conveyor data. Secondly, by using the screw conveyor data, the author makes a design of a belt conveyor as the replacement of the existing screw conveyor. As a result, the belt conveyor design has been created with a calculated capacity of 236.81 tons/hour, which is greater than the existing screw conveyor. and is designed not to be easily damaged due to the inclusion of steel grit as it happened in the screw conveyor. Keywords: Screw Conveyor, Belt Conveyor, Steel Grit, Blasting Room, Pillow Block, Capacity, Design

Abstract

Gear is one of the most important part of power transmission system in a vehicle, and as the time goes by there possibly some failure happened on the gears. However, there is no information provided by car manufacturer regarding the life and the material of the gears. This report presents the analysis of the planetary gear used in Toyota Rush AT year made of 2012. The objectives of the research are: to study the planetary gear mechanism and how it works; to analyze the force and stress acting on the gears; and to select a suitable gear material that can withstand against the loads that happen on the gear. The research methodology is started with finding the gear dimension and gear ratio. The force acting on gear is calculated based on the torque and rotation speed provided in car specification. Then the selection material is carried out based on the amount of stress applied on the gear teeth that were calculated using AGMA standard formulation. Finally, the fatigue life prediction of the gears is calculated based on the previous stress acting on the gears. The calculation result suggested AISI 1050 steel as the selected gear material that can carry the bending stress of 476 MPa and categorized as low to high fatigue cycle.
