Installation, maintenance, invalidation and correction measures of pulley transmission

1. Correct installation of belt transmission

(1). Switch off the electricity power, put off the shield and loose the assembly bolt of motor. Move motor to loose belt to a certain degree so that the belt can be take without prying the motor. Remember not to pry the belt.

(2) Take off the old belt to check whether it has any abnormity. Abrasion means there are faults on design of transmission equipment or maintenance.

(3) Choose appropriate belt to replace the old one.

(4) When cleaning belt or pulley, please use rag with little liquid of not-easy volatilization. It is neither correct to dip belt in the detergent or use detergent to scrub belt, nor use sand paper or spiculate articles to scratch in order to wipe off the dirt. Belt should be dry before using.

(5)Check whether the belt has any abnormal abrasion or crack. If the abrasion is beyond normal standard, please change pulley immediately.

(6) Check whether the pulley is of straight line symmetry. Pulley’s line symmetry is very important to the working of transmission pulley, especially synchronization pulley transmission equipment. (See Picture.1)

Picture 1:belt dissymmetry show

(7) Check others transmission parts, for example, the symmetry between bearings, durability and lubrication, etc.

(8)Never pry or use too strong power when installing new belt on the pulley.

(9) Tighten the central distance of transmission equipment till the tension testing instrument measures that the belt has proper tension. Rotate the main pulley several circles by hand to re-test the tension.

(10).Screw down the assembly bolt to justify the torque. Because when transmission equipment operating, any change of central distance will lead to bad performance of belt, make sure that all transmission assembly parts are screwed down.

(11). Start the equipment and observe the belt performance. Check whether there is abnormal shake, listen whether there is abnormal noise. It is better to turn off the machine and check the status of bearing and motor. If they feel too hot, perhaps the belt is too tight, or the bearings are of dissymmetry or the lubrication is incorrect.

2. Maintenance of belt and pulley

(1). The transmission belt should not be break and bent rapidly.

(2). During the storage and transportation process of belt and pulley, avoid sunshine, rain and snow, and avoid them contact acid, halogen, organic solvent steam and other matters which will affect them.

(3). When being stored under normal temperature, generally the temperature is 20-50 centigrade, and the heat resource should be at least one meter away.

(4). Avoid too large weight resulting distortion during storage. Do not fold, press and pile up, do not put the belt on the ground. The belt should be hung on the shelf or put on the shelf flatly.

(5). Pulley finished product should be stored and transported in dry and ventilated circumstance, and it should have rust resistance.

(6). Pulley transmission equipment should have shield, and should be under ventilation and pollution resistance situation.
