The article numerically simulates the vibration reduction of a spur gear transmission by using damping particles placed in technological holes designed on the gear itself. The vibration of the gear transmission is reduced based on friction and inelastic collision which eliminates the vibrational energy by the loss during the motion of the damping particles within the technological holes.

Gear is one of the most common and important components in machinery. Evaluation on durability of gears plays crucial role in the assessment of the whole system reliability and service life. For other parts like shafts, the gears also act as loads. Therefore, dimensions and weight of the gears should be reduced as much as possible, contributing the size and weight reduction of the whole systems, which is essential to be cost-effectiveness.

Failure and pitting of teeth of gear affects transmission error. So, aim of this study was to define optimal tooth modifications introduced by performing static contact and deformation analysis, while trying to design spur gears to resist failure and pitting of the teeth. Behaviour of unusual contact between flywheel ring gear and starter motor pinion was analysed and optimized root fillet was introduced in spur gear.

The undulating and sloppy geography, small size fields with uneven topography, lack of skilled labour, poor repair and maintenance facilities, low purchasing capacity of farming community and non-availability of improved farm implements and machines are some of the main reasons for low level of mechanization in the hilly region of the state. By keeping in mind the problems faced by the farmers in hilly areas and to promote farm mechanization a new type of rotary plough cum weeder is designed.

The objective of the present work is to use a suitable method that can optimize the process parameters like pulse on time (TON), pulse off time (TOFF), wire feed rate (WF), wire tension (WT) and servo voltage (SV) to attain the maximum value of MRR and minimum value of surface roughness during the production of a fine pitch spur gear made of copper. The spur gear has a pressure angle of 20⁰ and pitch circle diameter of 70 mm. The wire has a diameter of 0.25 mm and is made of brass.

1. Background of the Development The shape of gears is very attractive to the PM manufacturing process. Spur gears as well as helical gears can be shaped by compaction. The performance of gears is influenced beneath the geometrical design mainly by the material parameters tooth root strength σFE and pitting resistance σHlim. The comparison of these values from PM gears to wrought steel gears shows clearly, that PM gears can only be used in low loaded applications (Fig. 1).

A helical gear has teeth in form of helix around the gear. Two such gears may be used to connect two parallel shafts in place of spur gears. The helixes may be right handed on one gear and left handed on the other. The pitch surfaces are cylindrical as in spur gearing, but the teeth instead of being parallel to the axis, wind around the cylinders helically like screw threads. The teeth of helical gears with parallel axis have line contact, as in spur gearing. This provides gradual engagement and continuous contact of the engaging teeth.

We have discussed earlier that the slipping of a belt or rope is a common phenomenon, in the transmission of motion or power between two shafts. The effect of slipping is to reduce the velocity ratio of the system. In precision machines, in which a definite velocity ratio is of importance (as in watch mechanism), the only positive drive is by gears or toothed wheels. A gear drive is also provided, when the distance between the driver and the follower is very small.

W.M. Berg manufactures several styles of gears. Each gear has and serves its own particular application. Listed below are brief descriptions and application notes for the variety of available styles. Further information can be obtained from numerous gear and mechanical design handbooks, or by contacting our engineering department Gear Types Spur Gears are the most recognized style of gear. Spur Gears are used exclusively to transmit rotary motion between parallel shafts, while maintaining uniform speed and torque.

Established in Charlestown, Massachusetts Boston Gear was founded by none other than the man who invented the calculator - George Grant. Grant headed the business from 1877 to 1891, when it was sold to Frank Burgess, a businessman with one overriding goal: to provide accuracy, economy, and despatch, or, in today’s marketing vernacular, quality, price, and service - and indeed, those are the hallmarks upon which Boston Gear was built.
