What is the pulley size ratio?

[LaElla]

The ratio of the driving pulley diameter to the driven pulley = reduction ratio = 80/240 = 3, at which point the speed of the driven shaft is approximately 80r/min. If you want to reduce the speed of the driven shaft to 60r/min, the reduction ratio needs to reach 24. However, the speed ratio of V-belts is generally less than 10; otherwise, the wrap angle of the belt around the small pulley will be too small, reducing friction and causing the belt to slip easily. This not only affects the power transmission but also leads to rapid belt wear. Situations requiring a wheel alignment include: 1. Damage to the chassis and suspension due to an accident; 2. Replacement of the steering system and components; 3. Uneven wear on one side of the front or rear tires; 4. Replacement or adjustment of the suspension system. Wheel alignment involves adjusting the geometric angles of the tires, steering, and suspension components to ensure tight contact between the tires and the ground. The benefits of wheel alignment include: 1. Enhanced driving safety; 2. Reduced tire wear; 3. Maintaining a straight steering wheel when driving straight; 4. Automatic return of the steering wheel after turning, improved driving control, reduced fuel consumption, and minimized wear on suspension components.
