上充通大学 Shanghai Jiao Tong University Advantages of Different Transmissions3 Advantages of Gear Drives 1.Gear drives are more compact than chain or belt drives because center distances are minimum. 2.Gears have greater speed capabilities than either belts or chains. 3.Gears have a greater range of speed ratios than chains. 4.Gears can better transfer high power at high speed than either belts or chains can. 5.Metal gears do not deteriorate with age,heat or oil and grease and they do not develop static electric charges. 1111 Advantages of Different Transmissions3 Advantages of Gear Drives 1.
