17. What are the advantages of Gear drive?
Gear is a machine component with multiple advantages because of its ability to transfer mechanical power from one shaft to another. It is helpful for compact construction as the centre distance between the shafts is relatively tiny. It is highly efficient. It works well even at low speed. Its size is very compact in construction. Its velocity ratio always remains constant as it is used for positive drive. They have good longevity. Maintaining it is very easy as it only requires lubricant to ensure its smooth running.
