Whatever framework is embraced to coordinate the automobile to its thought process unit — be it a hand shift gearbox, a 'hot' shift gearbox or completely automatic unit, a complex and generally expensive mechanism is ordinarily included. More than expected plan office consideration is centeredaround this region of a recently imagined vehicle. Grounded plan systems for transmission gearing were accessible before the principal automobile or even the inner combustion motor was created; solid answers have in this way been generally accessible from the planning phase. The intricacy of the mechanisms has additionally requested, on account of amount delivered vehicles, thorough drawing designs of the variety of segments included with the goal that resilience stacking can be read and the requirement for exceptionally talented fitting, during get together, decreased. The present-day meaning of the creator's commitment is additionally improved by the need to guarantee without a doubt the base of expensive turn of events or creation changes. The cautious determination of gear ratios for a manual unit, or of control boundaries in an automatic one, can drastically influence the presentation or driveability of the completed vehicle.

The Comparative Study

This paper gives the comparative study among various techniques used to control the speed of three phase induction motor. Gear trains are one of the major reduction control technique in automobiles and the industrial sector. Present work focuses on the design development and analysis of a gear box with reduction. The objectives taken from the prior necessity, checked for three different motor speeds for better quality with low normal and high RPM. The motor connected to a reduction gear box known as differential gear box. The design analysed on the basis of motor speed that is RPM (2400 rpm, 6400rpm and 500 rpm). Material used for gear box and gears are EN24, the whole model developed in CATIA and the stresses observed in ANSYS. The possible output of initial analysis looks better than normal conventional materials.

Abstract Most of the Pharmacopoeia and other monographs that provide the quality specifications for botanicals typically contain identification and physicochemical tests, assays, and limits for contaminants. The assay methods generally involve quantitative determination of known organic compounds, commonly known as markers. The authors explore and propose that there is a need for additional approaches beyond markers, especially for botanicals derived from traditional knowledge and use. Preliminary data on few selected botanicals are additionally provided to communicate the thought process.

Spiral Bevel

Currently the fatigue testing of bevel gears are being done by using non rotating type of fixtures that applies fatigue load on a single tooth, which does not resemble the actual loading condition in an automotive differential gear box. This paper discusses the experimental setup with the noise and vibration analysis approach to determine the signature of failures of spiral bevel gears. The proposed experimental setup seems promising for further research and development in the fatigue testing of spiral bevel gears. The Crown pinion and wheel assembly is used for the testing. The pinion is connected to the electric 3 phase AC motor of 75HP with a suitable coupling and the crown wheel is mounted on the half axle shaft, which in turn is connected to an electric dynamometer. The speed/torque of electric motor and the load applied by the dynamometer can be varied. The acoustic sensor is mounted near the differential gear box and the accelerometers are mounted on the Pinion bearing, Crown wheel bearing and the half axle bearing. A four channel data acquisition system is used to log data in time domain (raw data) by three accelerometers and an acoustic sensor. The variations of sound pressure(dB) v/s time, sound Pressure(FFT-(RMS)) amplitude v/s Frequency, Acceleration v/s Time, Octave analysis i.e., Band power v/s Frequency, Noise spectrum Power v/s Frequency, Histogram, Power density v/s Time can be obtained. These data are then used to plot vibration and SPP levels in frequency domain to develop the noise and vibration signature of that crown pinion for given cycles of operation. The tests on Bevel pinion and gear set were performed in the BEC, Bagalkot NVH lab facility. The gear set run successfully at double the rated torque for 30 million pinion cycles. And the signature of pinion failure was obtained. The results demonstrated the suitability of using the given bevel crown pinion and gears set for specified speed, high load application in differential gear box of an automobile.

Pressure Changes

The hydroforming process of differential gear box for automobile under axial compressive load and internal bulging pressure was simulated and the load paths were optimized. The hydroforming process is divided into two steps. The deformation under different load paths was investigated using dynamic explicit finite element method. The distribution of equivalent strain and thickness was investigated as well. The simulation results show that the forming path for the first step is optimal when internal pressure changes linearly from 37MPa to 65MPa with the axial displacement.
