Intermediate bearing wear process and installation requirements

1. Intermediate bearing frame and welding gasket fabrication 1. 1 guy as creation, the intermediate bearing frame according to the hull to strengthen after initial positioning, in about 1 km away from mount fabrication location before and after a benchmarking in order to determine the mount in the future; Pull the light, in the mount position before and after playing axis of sample, before and after the position based on pole position 1. After 2 pull the light, the measured axis and the distance of the floor, identify intermediate bearing frame height direction after allowance for cutting, then according to the requirements of drawing size fabrication intermediate bearing frame 1. 3, in accordance with requirements of the drawings, in the middle bearing frame fixed panel welding gasket spot welding, the process to determine the rear welding can be performed, must be noticed when fabrication welding gasket slope direction, then welding gasket blows and achieve brushed with grinding process requirement 2. Temporary fixed 2 intermediate bearing. At the beginning of a host of shafting on top, on the middle bearing frame panel in advance four jack-up top position welding wire, and then install the intermediate bearing in the intermediate shaft neck, and pay attention to the intermediate bearing shell center to intermediate bearing flange end face distance requirements after 2. After 2 at the beginning of the host of the fabrication of around before and after the intermediate bearing interim adjustment silk with card, code tooling 3 host shaft load the initial installation 3 intermediate bearing before the adjustment. 1 shafting is inspection and connection bolt after the installation is complete, open the bearing cover, adjust the bearing base four top wire of high and low and temporary adjustment around the top wire, bearing lower bearing and shaft neck when clearance is zero, equal gap around 3. After 2 bearing shaft assembly, check on both ends of hole and shaft neck or whether the uniform clearances between 3. 3 will be on the combination of surface and internal control clean, clean lubricating oil 3. 4 the intermediate bearing with the clean copper gaskets, right on the 3 on the surface of bearing combination. 5 put the bearing cover overall on the bearing seat, and two taper pin bearing cover correctly position 3. Host shaft load adjustment of intermediate bearing protect the bearing cover mat about 2 mm high, must be coloring don't bring coated between bearing cover and bearing clearance position, face before and after the use of white cloth seal, prevent dust cabin, welding slag, impurities such as water vapor into the bearing seat in 5. Host pour glue after the installation of the intermediate bearing 5. Host 1 pour glue after 24 hours, in accordance with the requirements for the related parameters of intermediate bearing installation, conform to the requirements of the process, repetition measurement of intermediate bearing in accordance with 5 must meet the technical requirement. 2 number of intermediate bearing frame hole and drilling 5. 3 in the corners of each gasket measurement and welding gasket at the bottom of the bearing clearance, according to the experience and gasket blows with allowance, several processing is the thickness of the gasket, and the adjusting shim blows and blows with meet the inspection requirements can remove the adjusting shim drilling, drilling out the adjusting shim can be inserted at the bottom of the bearing seat and welding gasket, finally install intermediate bearing anchor bolt 5. After four intermediate bearing anchor bolt tensioning, remove four jack-up jackscrew intermediate bearing base, retest intermediate bearing load, conform to the requirements of the process, can be several processing positioning pin, and the pin hole 5. 5 remove the intermediate bearing wire temporary fixed around the top 5. 6 open the bearing cover, will jilt of oil pan installed in the tail end bearing oil cavity on the intermediate shaft, adjust to jilt oil pan Angle and the distance between the bearing Angle of ontology conform to the requirements of the drawing process of 5. About 7 check intermediate bearing clearance is uniform, adopt the way of lead wire conformed to the drawings requirements may check the total clearance. 8 inner cavity of the intermediate bearing bush thoroughly clean 5. 9 put the bearing cap on the bearing seat, and two taper pin bearing cover correct positioning, the bolt load and tighten, ensure that intermediate bearing installation integrity 5. 10 front end and intermediate shaft bearing gap in the middle position to install the rubber, in order to prevent the dust into the intermediate bearing
