  • Oct 08 2011 0183 32 This helps to keep the belt on the pulley It is also normal on long belts to twist them as shown in the diagram This can be seen in the above diagram and increases the angle of contact between the belt and the pulley Another technique to increase the angle is the use of idlers which are small pulley wheels that help to control slack in the belt...

  • Dec 28 2011 0183 32 Well I d think about what might be required for accelerating things up to speed and add a healthy margin for higher than intended belt tension it s pretty easy to create 100s of lbs of belt tension with adjusting screw tensioners and thermal expansion of components can add up too and try to keep the load under the endurance limit of the bearing conservative value published by SKF Co/8...

  • Jul 13 2020 0183 32 Consider an open belt drive rotating in a clockwise direction this rotating of the belt over the pulleys is assumed to be due to firm frictional grip between the belt and the pulleys When this frictional grip becomes insufficient there is a possibility of forwarding motion of driver without pulley with it this is known as the slip in a belt...

  • 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...
