- →Rotary Kiln
Rotary kiln is the main form of wear of gear damage after severe not ensure normal meshing and change, even if the tooth tip sharpening, are generally not broken teeth phenomenon. In order to reduce wear, in the repair of kiln ring gear made the flame surface quenching, quenching and tempering after. After years of use, wear very slight.
Rotary kiln according to the contact strength calculation of gear ring width: gear wear calculation has not mature calculation method, still according to the contact strength calculation, the allowable stress in terms of people wear influence.
Rotary kiln drive shaft and bearings: the end of the transmission shaft diameter is equal to the speed reducer shaft diameter, in order to determine a bearing inside diameter. Determination of each dimension, calculating fatigue strength. Try to use rolling bearing, calculation of life expectancy for8~10years. Calculation of axial force is not considered, but in the design should pay attention to the bearing axial fixation of less than 400 mm can be equipped with GZa type rolling bearing seat ( Q/ZB9273) bearing outside diameter of transmission shaft can also use other materials commonly used for steel.
Calculation of bending strength: kiln ring gear bending fatigue strength and bending strength is rich, almost no broken teeth. The calculation according to the general method. Gear ring structure size: tooth ring section and fixed mode, rotary kiln is introduced" I" shaped cross section, tangential spring plate fixing a broken circle.
