The gear is an important part of the gear reducer. For the helical planetary reducer, the gear plays an important role.If a good gear is used, the advantages of the gear reducer are as follows:

　　Compact structure: smaller space size than belt and chain drive.

　　Stable transmission ratio: Stable transmission ratio of helical planetary reducer is often the basic requirement for transmission performance.Gear transmission is widely used because of this feature.

　　High efficiency: Among the commonly used mechanical transmissions, the gear transmission efficiency is the highest, and the closed transmission efficiency is 96%~99%, which has great economic significance for high-power transmission.

　　Reliable work and long life: Designed and manufactured correctly and reasonably, using well-maintained gear transmissions, helical planetary reducers work very reliably, with a lifespan of up to ten or twenty years, which is unmatched by other mechanical transmissions.
