How to maintain agricultural machinery belt？

1、 Loading and unloading

Before installation, first check whether the driving wheel, driven wheel and tensioning wheel are on the same plane. Generally speaking, when the center distance between two pulleys is less than 1m, the allowable deviation is 2 ~ 3mm, and when the center distance is greater than 1m, the allowable deviation is 3 ~ 4mm. If the deviation is too large, it shall be adjusted to meet the requirements before installation and tensioning. During loading and unloading, the tensioning wheel shall be loosened first, or the wheel disc at one end of stepless speed change shall be removed first, and the belt shall be installed or removed. When the new V-belt is too tight for loading and unloading, remove a pulley first, and install the pulley after putting on or removing the V-belt. It is not allowed to remove it hard. Generally, the combined V-belt shall be loaded and unloaded after the pulley is removed.

2、 Tension

The tension of the drive belt is adjusted by the tensioning wheel. If the belt is too tight, the belt will be seriously worn, and if it is too loose, it is easy to slip, causing serious wear and even burning of the V-belt. Generally, when the distance between the two wheels is about 1m, press the middle of the triangular belt with your fingers and drop it vertically by 10 ~ 20mm. Check the tension of the V-belt during use and adjust it at any time.

3、 Replace

The V-belts shall be replaced in time after failure. If multiple V-belts are used together, if one or part of them fails, the other ones shall be replaced at the same time, and the old and new belts shall not be used together.
