WebAug 28, 2015 · The result of the belt slipping is to reduce the velocity ratio of the system. As the slipping of the belt is a common phenomenon, thus the belt should never be used where a definite velocity ratio is of importance (as in the case of hour, minute and second arms in a watch). Belt slip indicator is used to indicate that the belt is slipping WebTypes of belt damage to watch for are cracking, which can be caused by excessive heat and dust; stretching; added load damage; and damage as a result of belt whipping. Cracking Cracking can be caused by exposure to high temperature and/or dust.

WebEffects Of Creep The ability of the material to flow under the effect of temperature is known as creep. It is basically a time dependent phenomena, observed after long period of time. The deformation of solid in creep occurs due to the stresses developed in the body known as mechanical stresses. WebBelts (or chains) are used to transfer power (or convert torque) through rotational motion from one shaft to an other. Belt driven fans are common in heating, ventilation, air-conditioning and cooling (HVAC) systems. Chain are common in many transmission systems like bicycles and other.

WebCreep: When a belt rotates through two pulleys, the upper side of this drive will be in tension i.e. tight side and the lower side will in compression i.e. slack side.
