1. Spur gears are mounted in series on parallel shafts to achieve large gear reductions.
Spur gears are the most often used gears and are used in sequence for massive gear reductions. Spur gears have straight teeth that are positioned in parallel on different shafts. Spur gears can be found in washing machines, screwdrivers, wind-up alarm clocks, and a variety of other equipment. These are very noisy because the gear tooth engages and collides. Spur gears are not employed in machinery like vehicles since each collision produces loud sounds and generates vibration. A typical gear ratio range is from 1:1 to 6:1.
2.Helical gears operate more smoothly and quietly compared to spur gears due to the way the teeth interact.
A helical gear's teeth are cut at an angle to the gear's face. When two teeth begin to engage, the contact is gradual, beginning at one end of the tooth and continuing as the gear rotates towards full engagement. The helix angle typically ranges between 15 and 30 degrees. The thrust load is proportional to the size of the tangent of the helix angle. Helical gears are the most frequent type of transmission gear. They also produce a lot of thrust and utilize bearings to withstand the thrust load. When installed on perpendicular shafts, helical gears can be utilized to alter the rotation angle by 90 degrees. It has a standard gear ratio range of 3:2 to 10:1.
