Swinging conical broken bowl shape tile bearing looseness, migration, how to do?

Swinging conical broken bowl shape tile bearing looseness, migration, how to do? 2018 - 07 - 16 cone break is one of the mainstream of the current mining crushing equipment, will inevitably encounter various problems in the production, bowl tiles bearing looseness, offset, swing is the common types of problems. Fault has no size, once produce loose, not only easy to damage spare parts, cause equipment accident, and pose a safety hazard. Bowl tiles bearing looseness, offset, swinging reasons: 1, bowl watts bearing installed on the base, bowl should cooperate closely with the base, bearing and feeler check level contact closely, such as clearance can not meet the assembly requirements of the above will appear. 2, crusher, iron or feed do not conform to the requirements of the equipment performance, namely, such as crusher through the iron more than row ore granularity, feed particle size is too large, or shoes is too big, can cause the captain of the broken time vibration, resulting in bowl bearing wear and base, can not meet the assembly requirements of the above will appear. 3, bowl bearing seat and the base assembly design is unreasonable, bowl tile bearing pedestal installation requirements is a tight fit, due to the site installation, spare parts size is bigger, does not have interference assembly condition, is to design a shaft pin as a limit, the crusher through the iron more than row ore granularity, feed particle size is too large, or shoes too large crusher vibration caused by circumstances, it is very difficult to limit. Bowl tile bearing pedestal and loose, the influence of offset, swing: 1, caused by moving cone coaster coaster will increase the oscillation amplitude of dynamic cone ( If the row ore mouth adjust inappropriate) , leading to a fixed plate and the active plate collision, the light is stuck, or cause crack plate touch. 2, assembly dimension change, fluctuation of bowl after tile bearing seat and the base to loosen, will lead to the moving cone of spherical surface and bowl can not meet the assembly requirements, dynamic cone and eccentric shaft assembly clearance, horizontal bearing shell and bowl tile burning equipment accident. 3, maintenance quality cannot guarantee because the bowl tile bearing seat and the base assembly clearance can not meet the assembly requirements, if not timely should be fixed firmly, can affect the maintenance of equipment as a result, especially in dealing with cone break 'speed'. Cone broken completely conform to the requirements of the running test 2 hours after repair, but if the pick-up test will appear 'speed' phenomenon. As long as to produce the vibration 'speed' phenomenon, may appear, in turn, will lead to failure or other accidents. 4, to increase the maintenance cost due to this kind of design and assembly form, will often appear equipment failure or accident, virtually increased the labor intensity of maintenance personnel and the maintenance cost. This is cone broken bowl shaped tiles bearing looseness, offset, oscillation, the common cause and influence of the fault has no small matter, once appear, problems to solve, must not allowed, so as not to do more harm than good.
