The belt drive uses friction or meshing between the belt and the pulley to transmit movement and power. Because the belt drive has the advantages of smooth transmission, simple structure, low cost, no lubrication, buffering and absorbing vibration, it is widely used in agricultural machinery. When using a triangular belts, please pay attention to the following.
The triangular belts (also called the triangular belts) is a standard part and is produced by a professional factory. For the triangular belts (triangular belts), the original standard is divided into O, A, B, C, D, E, F seven according to the size of the cross section. The new standard is divided into seven models: Y, Z, A, B, C, D and E, and their cross-sectional dimensions increase sequentially. Commonly used triangles have four types: Y, B, A, and B. The replaced triangular belts should be the same as the model of the pulley groove, and the length of the replaced triangular belts and the original triangular belts should be equal to the length required by the design (the type and inner circumference of the triangular belts are printed on the outside of the tape. Please be careful Observed). When choosing, please choose different types of triangular beltss according to the power and size of the pulley groove.
When installing, please note that the axes of the main pulley and the driven pulley should remain parallel; the grooves must be on the same plane and cannot be twisted; the tension of the triangular belts must meet the requirements; when driving multiple triangular beltss, the The length and tension must be basically the same; and a protection cover is installed. Before installation, make sure that the two planes of the driving wheel and the driven wheel are on the same plane. When installing the triangular belts, do not use iron tools to force it in. This will severely damage the prying part of the triangular belts, causing peeling between the inner layer and the firm layer of the triangular belts, or skin scraping, causing the prying part to become loose. It is also possible to pry up the triangular belts pulley groove. The correct installation method is: loosen the tensioning device, then press the triangular belts into the groove of the pulley by hand, and finally tighten it.
In order to ensure the normal operation of the triangular belts, the use of the triangular belts should be checked regularly. If there are serious wear, cracks, aging, folding and other defects, it should be replaced in time. If it gets oily, clean it. If the installation is too tight and the triangular belts is severely deformed, the life of the triangular belts will be shortened. At the same time, the bearing will generate heat due to excessive radial force, thereby accelerating the damage of the bearing. If it is too loose, the driven machine will not reach the rated speed or even skid. Check the fastening method of the triangular belts, add a vertical load of 2kg in the middle of each belt, and the sag is 30-50mm. 4Maintenance of belt
(1) When checking the tension of the triangular belts regularly, it cannot meet the specified requirements after adjustment, and a new triangular belts must be replaced. When replacing, all belts on the same pulley should be replaced at the same time, otherwise the load on the triangular belts will be unevenly distributed due to the difference between the old and the new and the difference in length. This will cause the triangular belts to vibrate and drive unevenly, thereby reducing the transmission of the triangular belts. Work efficiency.
(2) During use, the working temperature of the triangular belts should not exceed 60 "C. Do not apply belt grease at will. If you find that the surface of the triangular belts is shiny, it means that the triangular belts has the first to remove the dirt on the surface of the belt, and then Apply an appropriate amount of belt wax when cleaning the triangular belts.
