Open Gear drives are very common in the raw materials industry. The girth gear drives that are used in tube mills, coolers, washing drums, kilns, calciners and other machines have to transmit enormous torques‚ often up to 50,000 Nm. It is only natural that this kind of force subjects the gear wheels to very high stresses.
Basics of Grinding Fundamental Manufacturing Processes Video Series Study Guide 2 Another aspect of grinding wheels is their pore structure or density, which refers to the porosity between individual grains. This pore structure creates spaces between the grains that provide coolant retention and areas for the chips to form.
