Gear drives have many competitors. It is therefore worthwhile to look at whether gear transmission is the most suitable way to deliver energy. The main competitors are belt (flat, triangular and toothed) drives, chain drives and rollers, reversing and friction drives that are re-starting in speed regulation. Hydraulic or electric drives may be best suited for specific applications where they have the advantage of being able to store certain energy for speed regulation. (1) It is extremely compact and therefore particularly useful when space is limited, and belt or hydraulic transmission is more advantageous for long distance transmission. (2) It requires lubrication, which may be a strength or a shortcoming. (4) Synchronous transmission can be realized. For many applications it is necessary to have a precise speed ratio, but belt slippage and hydraulic slippage help to share the overload. (5) Make the direction change (often appearing). (6) When the load is high, the installation offset is not allowed. (7) The requirements are very accurate. Generally speaking, the pitch diameter deviation must not exceed 20MM, and the error of the toothed belt drive can reach 200mm. (8) Gear transmission is cheaper than hydraulic or electric transmission under high torque conditions. (9) In the case of high torque, if the accurate gear is used, the gear drive is lower than other transmission noise, but in the case of low torque, if it is dislocated, it may be a noise source.

Gear transmission has the following characteristics:
(3) Good rigidity, this may also be a strength, or it may be a shortcoming.
(l0) can work at very high speeds. Unlike belt drive, its transmission speed should not exceed 200r/min.
When deciding to choose, the final trade-off is of course the cost. Gear drives generally have significant advantages in high torque situations, such as the final drive of marine propulsion. But at very low torques, there may be a lack of competitiveness.
