Question
Choose all the options that contains incorrect information. Explain the reason and please correct the sentence.
Design considerations of various types of gears are one of most important aspects of machine designing. Here are some basic types of gears and how they are different from each other. [11Spur gears are mounted in series on serial shafts to achieve large gear reductions. Spur gears are used in washing machines, screwdrivers, and other devices. [2]Helical gears operate more smoothly and quietly compared to spur gears due to the way the teeth interact. When two of the teeth start to engage, the contact is gradual-starting at one end of the tooth and maintaining contact as the gear rotates into full engagement. [B]Bevel gears are used to change the direction of a shaft's rotation. Bevel gears have teeth that are available in straight, spiral, or hypoid shape. [4]The pinion and gear are often always opposite hand and the spiral angle of the pinion is usually larger than the angle of the gear. Worm gears are used in large gear reductions. [5JThe setup is designed so that the gear can turn the worm, but the worm cannot turn the gear.Explanation / Answer
Answer
1) In Spur gears, two parallel and coplaner shafts are connected by gears to increase or decrease in speed.
5) worm turn the gear but gear can't to make the system irreversible.
