Write a paragraph (120 - 140 words) about different types of gears using the following suggested questions.What is a gear?What are its functions?How many common types of gears are there? What are they?What are their features?What are their applications?
Solution
A gear is a mechanical component with teeth that mesh with another gear to transmit torque. Its primary functions are to change the direction of rotation, increase or decrease the speed of rotation, and to move rotational motion to a different axis. There are four common types of gears: spur, helical, bevel, and worm. Spur gears are the simplest, with teeth parallel to the gear's axis. Helical gears have teeth cut at an angle, allowing for smoother and quieter operation. Bevel gears have teeth that are cut on an angle, allowing them to connect intersecting axes. Worm gears are used to transmit power at 90 degrees and are highly efficient. These gears are used in various applications, from watches to automobiles, depending on their specific features and advantages.

Task 1: Read the text and fill in the blanks with NO MỎRE THAN THREE WORDSSpur gear is the simplest type of gear with teeth projecting towards or away from the centre. The edge of each tooth is straight and aligned parallel to the axis of rotation. Spur gears are used in low-speed applications and in situations where noise control is not a problem. It tends to be noisy at high speed.Helical gears are similar to spur gears except that their teeth are cut in a spiral shape. The angled teeth engage more gradually than spur gear teeth do, helping them run more smoothly and quietly. Helical gears are used in high-speed applications, large power transmission, or where noise control is important.Some helical gears have just one continuous tooth. These are called worms. A worm pairs with a worm gear, which helps reduce speed.A rack and pinion is a type of linear actuator that comprises a circular gear (the pinion) engaging a linear gear (the rack), which operate to convert rotational motion into linear motion. In other cases, a machine transmits power at an angle. This requires bevel gears. Bevel gears have a conical form and can be used to transmit rotational power through shafts that are typically at an angle of 90 degrees to each other.Spur gears have teeth projecting towards or away from the centre. They are used in applications and cannot control noise at high speed.Helical gears have their teeth cut in a spiral shape. They are used in high-speed applications, large power and can control noise.Worm and worm gears have just one continuous tooth with a worm gear. They help reduce speed.A consists of a circular gear engaging a linear gear.
