Jaw Crusher for-watt scraping gap adjustment technique

Initially, the removal of old tile jaw crusher ought to be completed (1) the old bearing joints measure the thickness in the tile spacers. (2) measuring the level of the spindle. (three) Meticulously verify the shaft is smooth, whether there's corrosion, scratches and other defects, if any should try to eliminate. (four) Measure the old bush headspace, backlash and axial clearance. Second, the speak to detection jaw crusher machine tile back and bearing case In accordance with "JB / T5000.10-1998 assemble heavy machinery - General requirements" needs, have to be well-watt back-scraping to attain the necessary technical requirements. Otherwise, equipment operation prone to slippage or reverse rotation among the bearing plus the bearing. To prevent this from happening, it can be usually made use of pin and sleeve positioning. Third, the bush scraping the technical specifications In accordance with "JB / T5000.10-1998 heavy machinery assembly Common technical conditions" in the claim, the spindle scraping should really meet the following technical requirements. (1) The spindle and bearing both even and close contact with, but in addition a specific fit clearance, the upper, lower than the make contact with angle on the spindle bearing portion is formed wedge as well as the wedge started a gradual transition in the tile in the maximum to zero. (two) the speak to angle is not as well huge nor too compact. The get in touch with angle is as well small, will improve stress bearing, bearing significant cause greater deformation, accelerated put on and shorten the service life; the make contact with angle is as well substantial, it will influence the formation with the film, destruction lubrication. Therefore, with out prejudice to the pad under stress conditions on the premise, the make contact with angle as compact as you possibly can. (three) The actual get in touch with pattern inside the variety with the contact angle the more, the much more detailed, the much more uniform the greater.
