Standard electric chain hoist, its gear is generally used helical gears, helical gear has a benefit is to reduce the impact of gear bite, thus prolonging the service life of gears.

If there is a problem with the gears, then it is likely that the design is unreasonable or shoddy products, of course, may also be due to the installation of substandard.


1. Tooth root. Tooth root crack is usually a main cause of gear abnormality. The uneven internal distribution of gear material results in the bearing process, sometimes lead to a certain fatigue crack in the tooth root of gear, then it is likely to cause full tooth fracture.

2. Tooth surface. Tooth surface is more prone to wear, but there are two types of wear, abrasive wear or corrosive wear. Abrasive wear is probably because the gourd in the installation and debugging unreasonable caused, after all, if the installation of inappropriate words can easily cause the gear working ability is consumed, this situation will cause the tooth surface is worn. If it is corrosive wear, it is likely that the material and some lubricants in the matter produced a chemical reaction;

3. Gear itself. If you are in the process of using, find the problem of gears, it is likely that the gear itself, the gear itself will appear broken. One of the reasons why gears are broken is that they may be overly fatigued or overloaded. Both cases may cause the gear itself to break;

The above is the electric chain hoist gear The cause of the problem, want to know more details, welcome to call in detail.
