Do you know what gear drives need to meet?

Gears need to be used in many mechanical devices. Gears act as transmissions. The quality of the gear itself can seriously affect the effect during use. So, if you want the gear drive to perform better, what conditions do you need to meet? Now we mainly want to tell you the conditions that the gear transmission needs to meet. Hope our introduction is helpful to you.

The conditions that the gear transmission needs to meet

1. The accuracy of the transmission motion requires the gear to transmit the motion more accurately, and the transmission ratio is constant. That is to say, the angular error of the gear during rotation does not exceed a certain range.

2. The stability of the transmission motion requires the gear transmission movement to be stable to reduce the impact. Vibration and noise. That is, to limit the change of instantaneous speed ratio when the gear is rotated.

3. Load distribution uniformity requires that when the gear is working, the tooth surface contact should be uniform, so that the gear will not cause the contact stress to be too large due to the uneven load distribution, resulting in premature wear of the tooth surface. Contact accuracy includes not only tooth surface contact uniformity, but also contact area and contact position.

4. The rationality of the transmission side gap requires that when the gear is working, there is a certain gap between the non-working tooth surfaces to store lubricating oil and compensate for the temperature. Dimensional changes and machining due to elastic deformation. Some errors in the assembly process. The manufacturing accuracy and tooth side clearance of the gear mainly depend on the use and working conditions of the gear.
