Abstract – Gear box have complicated geometry and must
may require some simple analysis. After the selection of the concept to be applied for the solution, the detailed design and analysis are performed as the sixth step of design.
satisfy Design criteria such as strength, weight, manufacturability and performance. Gearbox need to accomplish a lot of engineering objectives including some necessary performance durability requirements. Gearbox design and development is very time consuming, because it needs a number of tests and design iterations before going into production. In modern industry how to shorten development time and to reduce the number of times test are important issues.
Vasim Bashir Maner, M. M. Mirza, Shrikant Pawar [1]: This paper contains the gearbox foot casing optimization. Foot casing is a part of gearbox, it provides support to the shaft, bearings and hence the gear loadings. In Top Gear Transmissions industry, foot casing is made by cast iron material which weights around 71.6 kg. It is approx 32.6% of entire gear-box assembly. Now, industry is facing problem in excessive weight of foot casing. It is not as per optimum design. So there is more wastage in material and ultimately consumes more cost for casting as well as for machining. To solve this problem it is essential to carry out the analysis of foot casing and redesign the existing foot casing in order to save material as well as cost. 3D model is generated in PRO-E software, while static analysis is done in ANSYS software. Optimization is based on ANSYS results.
Key Words: Gear box, strength, weight, durability.
1. INTRODUCTION Engineering design is the process of devising a system, component, or process to meet desired needs. It is a decision making process (often iterative), in which the basic sciences, mathematics, and engineering sciences are applied to convert resources optimally to meet a stated objective. Among the fundamental elements of the design process are the establishment objectives and criteria, synthesis, analysis, construction, testing and evaluation.
R. V. Nigade Prof. T.A.Jadhav A.M.Bhide [2]: The 3-D solid model of the gearbox top cover was built using Autodesk Inventor®. ANSYS workbench 13® was used for preprocessing, solving and post processing. Modal analysis involved extraction of mode shapes and natural frequencies. Impact testing using hammer excitation was used to experimentally determine the vibration properties of the gearbox top cover. The results obtained by FEA modal analysis are compared and validated against modal test data.
The primary way that engineers utilize the forces and materials of nature for the benefit of mankind is through new and innovative designs. The first step into a design study is to recognize the need. The need, which is the purpose of the design study, is established via a general statement of the client’s dissatisfaction with the current situation. Problem definition is the second step of design which should include all the specifications for the thing that is to be designed, the constraints on the design, design considerations (strength, fatigue life, cost etc.) and the criteria to be used for evaluating the design according to the design considerations. The third step is information gathering which requires collection of related information, including theoretical information and previous studies on the subject, from the available sources. Concept generation comes as the fourth step of design, which is the most creative part of the design process. Concept generation is followed with concept selection, in which the generated concepts are compared with respect to basic design criteria. This step

M. Sofian D. Hazry K. Saifullah M. Tasyrif K.Salleh I.Ishak [3]: This paper contains the study about vibration analysis for gearbox casing using Finite Element Analysis (FEA). The aim of this paper is to apply ANSYS software to determine the natural vibration modes and forced harmonic frequency response for gearbox casing. The important elements in vibration analysis are the modeling of the bolted connections between the upper and lower casing and the modeling of the fixture to the support. This analysis is to find the natural frequency and harmonic frequency response of gearbox casing in order to prevent resonance for gearbox casing. From the result, this analysis can show the range of the frequency that is suitable for gearbox casing which can prevent maximum amplitude.
