The flour mill equipment bearing replacement

The flour mill equipment of 2019 - bearing replacement 02 - 01 flour mill processing equipment is the skin and slag grinding and whey powder system to obtain relatively pure endosperm of ground into a powder, at the same time as far as possible to reduce wheat skin and wheat germ and broken. For mill can't replace the bearing or not to fall apart or roller presence of pitting to determine, for measuring roller clearance between inner surface and outer raceway. 1, measure the new initial radial clearance of the bearing. Initial gap is the difference between different manufacturer of bearing, SKF or FAG, initial bearing clearance is zero. 065 - 0. 090mm。 When using multiple times, after bearing the initial clearance, when the clearance reaches 0. 14 mm, should replace the bearing. 2, for each replacement roller, measuring the initial clearance. When the new bearing, can be directly measured with a feeler gauge; Used in bearing, oil use gasoline or kerosene must be removed, to measure again. When measuring, feeler through a two race. 3, when installing bearing measurement of bearing radial clearance after assembly. Measuring, bearing clearance with a feeler or at the top of the central position in the bottom of the bearing measuring roller clearance between inner surface and outer raceway. If supported by grinding roller bearing, measuring the position in the middle of the bottom. If is bearing support roller, measuring the gap at the top position. 4, the control of bearing radial clearance on the service life of bearing and roller rotation accuracy is very important. Bearing, installation and adjustment to the bearing radial clearance is 0. 035 - 0. 045 mm, the bearing outer ring can rotate with a little force. 5, bearing disassembling and cleaning, lubrication, and must be in strict accordance with the mill specification order. 6, the use of special tools, put an end to pry, hit, such as irregular disassembly, the accuracy of bearing damage.
