Before loading and unloading, it is necessary to check whether the driving wheel, the driven wheel and the tensioning wheel are on the same plane. In general, the allowable deviation is 2 to 3 mm when the center distance between the two pulleys is less than 1 m, and 3 to 4 mm when the center distance is greater than 1 m. If the deviation is too large, it should be adjusted to meet the requirements before installing and tensioning. When loading or unloading, firstly loosen the tensioning wheel, or remove the non-polar shifting end wheel first, and attach or remove the belt. When the new V-belt is too tight for loading and unloading, it is necessary to remove a pulley, install or remove the V-belt, and then install the pulley afterwards. The general group V-shaped belt should be removed after the pulley is removed.
The tension of the tensioning belt is adjusted by the tensioning wheel. If the belt is too tight, the belt will be worn too much. If the belt is too loose, slipping is easy to occur and the triangle belt is seriously worn or even burned. Generally about two meters away from the track, press the middle of the triangle belt with your finger and it should be lowered vertically by 10 to 20 mm. The tension of the V-belt should be checked during use and adjusted at any time.
Replace the V-belt after the failure should be promptly replaced. If more than one V-belt is used, if one or some of the V-belts fail, the others should be replaced at the same time. The old and new tapes cannot be used together.
