Differences Between Spur Gears and Helical Gears

[DiKaden]

Here are the differences between spur gears and helical gears: I. Different in nature: (1) Helical gear transmission: A commonly used component in mechanical transmission, gears are made of high-quality, high-strength alloy steel. (2) Spur gear transmission: A classification method of gears. II. Different advantages: 1. Advantages of helical gear transmission: (1) Better meshing performance: The meshing process of helical cylindrical gears is a gradual transition, with the force on the tooth surface increasing gradually from small to large and then decreasing; helical cylindrical gears are suitable for high-speed and heavy-load applications. (2) Larger overlap ratio: The increase in overlap ratio enhances the load-bearing capacity of the gears, thereby extending their service life. The overlap ratio mainly depends on the meshing time, and the long meshing time and large contact area of helical gears reduce stress. Stable transmission and economic growth. (3) Compact structure: The smaller the minimum number of teeth, the more compact the structure. 2. Advantages of spur gear transmission: Strong load-bearing capacity and durability.
