What are the advantages of belt drives over gear drives?
The advantages of a belt drive include:
- Belt drives are cost-effective.
- They are simple to use.
- Belt drives do not require parallel shaft.
- They have a low maintenance cost.
- They come with overload and jam protection.
- Different speeds can be obtained by means of step or tapered pulleys.
What are the advantages and disadvantages of gear drive?
It requires proper lubricant and reliable process of applying it, for the proper operation of gear drives. As the manufacture of gears requires special tools and equipment, thus it is costlier than other drives. The inaccuracy in cutting teeth can cause vibrations and noise through operation.
What is the difference between gear drive and belt drive?
Therefore, gear drive is one engagement type positive drive that is used to transmit motion, torque and power between driver and driven shafts, preferably over short distance. On the other hand, belt drive is a friction drive that is specifically suitable for medium to larger distance power transmission.
Which among the following is an advantage of using belt drives over chain drives?
Which among the following is an advantage of using belt drives over chain drives? Explanation: The greatest disadvantage of using chain drive is that it produces noise which can overcome by the use of belt drives. The other factors such as cost, durability and efficiency are good for chain drives. 6.
What are some advantages of gears?
They are used for large reduction in speed and for transmission of torque. Gears require only lubrication, hence less maintenance is required. Using gear systems, we can transmit motion between non-parallel intersecting shafts. They are used for positive drive, so its velocity ratio remains constant.
What are advantages of V-belt over flat belt?
Advantages of V-belt drive
- High power transmission capacity because V-grooves provide excellent grip.
- The functioning of the belt and the pulley is smooth and quiet.
- The V-belt drive provides compactness due to the small distance between the centers of the pulleys.
- Slip between the belt and the pulley is negligible.
What is the advantages and disadvantages of belt?
Belts are the cheapest utility for power transmission between shafts that may not be parallel. Power transmission is achieved by specially designed belts and pulleys. Belts run smoothly and with little noise, and cushion motor and bearings against load changes, but has less strength than gears or chains.
What are the advantages and disadvantages of flat belt drive?
Advantages of Flat Belt Drive.
- The flat belt drives are simple, less expensive, flexible, and durable.
- This belt drive gives better performance at high speeds and is more economical to use.
- This can withstand high load and have a long life.
What are the advantages of flat belts over V belts?
The wedging action of the belt in the groove gives high value of limiting ratio of tensions. Therefore the power transmitted by V-belts is more than flat belts for the same coefficient of friction, arc of contact and allowable tension in the belts.
What are the advantages of belt drives?
Another advantage of belt drives is the elasticity of the belts compared to rigid gears. This offers good damping characteristics (shock absorption), especially in the case of sudden torque changes.
Advantages Of Gear Drive: Positive drive and has more efficiency than belt and rope drive. Operation of drive is simple and effective. Life is more compared to other drives. With one input speed, no. of output speeds can be obtained by using suitable gear drive. Safe and compact.
What are the disadvantages of a V-belt drive?
It costlier as compared to the flat belt. V-belt drive can’t be used for long distances due to a greater weight per unit of length. It may be not applicable to synchronous machines because they are not free from creep. The centrifugal tension prevents the use of belts at speeds below 5 m/s and above 50 m/s.
What are the advantages of chain drive mechanical drives?
Chain Drive Mechanical drives. Advantages of Chain drive; Positive drive as there is no slip, hence constant velocity ratio. Oqupies less space compared to belt drive. Life is more compared to belt drive. Used for large center distance. Transmission efficiency is larger than belt drive.
