Maintenance of the lower bearing. Grader lower bearing there are two structural forms: one rolling bearing; two rubber bearing support. Rolling bearings are sealed main causes of damage cause bearing damage leaked into the mine, the main reason for sealing leaks mainly wear loose packing and high pressure Grease is not timely, maintenance, replacement bearings, and repeatedly Oil asbestos packing compaction compaction, will support all internal cavities filled with grease lubrication should be used regularly in order to maintain a certain degree of support within the external pressure, to avoid pulp invasion, responsibility for operation and maintenance workers require a higher. Spiral classifier specifications depend on the size, it generally takes 4 N/12h, convenient and fast, compared with the first method, save more than half the time, the disadvantage is short-lived life after repairing, usually 9-15 months, the using manufacturers according to their production task completion and grading machine spindle fracture extent decide which methods to repair or completely replaced. After years of development, our technology on sand making machine has become mature which should be attributed to the combination of advanced technology from abroad and the development tendency in domestic market. The mobile crushing plant has the benefits of effortless transportation, low transportation price, flexible configuration, easy maintenance etc.
Under normal circumstances bearing assembly life of up to one year, but the fuel assembly quality problems or is not timely, sometimes life of less than one month. Many use this sealed bearing units made ??improvements, the more successful is to replace oil asbestos packing rubber or polyurethane material of the V-ring, multi-ring superimposed together instead of asbestos packing, because rubber and polyurethane its excellent elasticity and abrasion resistance, the sealing performance was significantly improved compared to asbestos packing, stabilize and improve the service life of rolling bearings. Factors affecting the service life of rolling bearings are more, difficult to grasp the life cycle, usually in monthly plan overhaul open inspection, into the plasma damage to the bearing is replaced, and high maintenance costs. Some manufacturers will use rolling bearings into a rubber or polyurethane bearing support, coupled with the short axis of the lower bearing steel liner, bearing service life of up to 3 to 6 months, steel bushing life of up to 8 N12 months, life cycles, easier to control, to master the law of its life cycle, you can effectively control its planned maintenance, periodic replacement of bearings and steel bushing, the workers responsible for the operation and maintenance requirements are lower, and lower maintenance costs .
There is also a more simple method of repair and renovation of the rolling bearing assembly disassembly, with hollow shaft flange, short axis intact, bearing inner roller bearings, glands, packing, before and after removal of the gland, only retention support casing, use of the old roll with a width of the conveyor belt with the same axial width of the housing, the housing outer diameter slightly smaller than the inner diameter, outer diameter slightly larger than the minor axis of the rubber belt supporting roll, into the housing, set into the short axis, it is made of a simple rubber belt lower bearing, the belt roll pay attention to the direction of the support roll against the minor phase shift to ensure that the screw shaft is rotated, the belt and the support surface of the housing bore squeezing. Belt reel life of up to three months or more, the method is simple, do not need another production of machined parts, less investment, the use of waste conveyor belt, low cost, and stable, reliable, long-term application.
