Abstract – Portal axles are an off-road technology where
•
the axle tube is above the center of the wheel hub and where there is a gearbox in the hub. Because of that ground clearance is increased. This reduces load on the axle crown wheel and differential. In this project the design of portal axle elements as input shaft, output shaft, gear train, casing & bearings is to be analyzed. The performance of spur gear train is determined. The objective of project is the comparative study of spur gears is analyzed with the analytical as well as experimental results.
In helical gear wearing capacity is less.
Material Selection: Cast steel was use to manufacturing the gears of the portal axel because it has high melting point. Melting allowed other elements, such as nickel, to be mixed into the metal, thus strengthening the steel Cast steel has a rough finish. In future work different composite materials can be used for analysis of input and output shaft of portal axle unit. Table -1: Properties of Cast Steel
Key Words: Gear, Pinion, Input Shaft, Output Shaft, Bearing, Casing.
1. INTRODUCTION
Figure 1 The output shaft, input shaft, bearing, casing and gear train is mainly design for portal shaft. With the help of CAD model (CATIA, UNI GRAPHICS) and ANSYS software we can do the analysis by FEA method. For better result experimental analysis can be performs. When the spur gear is compare with helical gear the advantages are follows: Spur gear can withstand at more stress and vibrations. •
Reliability of Spur Gear is more.
•
Spur gears are easily manufactured & compact.
•
Helical gears engage more gradually than do spur
2. Layout and Design of the Setup -
gear. •
Helical gears are highly durable & transmit more torque.
