Modeling the damages of belt gears

Abstract

This paper looks into the problem of choosing a driving belt for a drive. The previously developed selection of algorithms was subjected to another evaluation that helped us recognize the need for changes indicated in developing new designs of drive belts. The new algorithm will be tested by simulating the operating conditions of the transmission, to which the right belt must be selected. Damage assessment after operation and belt selection allows for the identification of a new coupling model. By presenting the relationship between specific failure cases and the parameters of the coupling model, we can see the functionality of the selection algorithm. There may be multiple belt transmission damages. The feed may be broken; the surface may be damaged; the same applies to the edges. Furthermore, the wheels and bearings may be damaged too. The belt can have many additional functions that affect its operating parameters. Next to the drive function, the belt often performs conveyor and control functions. Thus, additional types of damage occur in belts with additional functions. The number of causes of their occurrence is also growing. For example, any damage to the sling in the passenger elevator can endanger the life of the passengers. Intensive research is being carried out on the real-mode damage monitoring systems. Specific failures are being monitored, and appropriate systems are being designed for them. Therefore, it is important to investigate the damages to belt transmissions, modeling their course of progression and causes.
