The bearing in the toilet paper processing equipment is disassembled pay attention to safety matters

The bearing in the toilet paper processing equipment is disassembled pay attention to safety matters - 2020 10 - 04 toilet paper processing equipment in the bearing is equivalent to the human body joint, although small, but the effect is very big, if improper maintenance and replacement, will seriously affect the production of papermaking machine. Retractor should take hook bearing inner ring, and should not be snagged on the outer ring, so as to avoid bearing damage or excessive; Puller when used at the center of the hole, in order to make the screw, not skewed orientation axis. Should also be pointed out that volume by the bearing force under the condition of the transmitter, bearing damage and retractor; To prevent slippage retractor. With feet into Angle is less than 90 & deg; 。 Using the pressure bearing, smooth and reliable, won't damage the machine and the bearing pressure method. Promote the hand press, hydraulic press or mechanical. Note: the press should be focused on the central axis, instead of partial pressure. Fourth, work closely to remove heat remove bearing method. Was first heated to use about 100 oil in oil can be split bearings, bearing ring, until the thermal expansion of the bearing can be pull out. Remove doppler should be installed on the bearing, and exert a certain force; Before heating, or in the use of asbestos rope winding thin iron shaft, heating the shaft, to prevent swelling, toilet paper processing equipment remove bearing from bearing shell hole will be difficult to unload, bearing hole only heating shell, bearing not heating; Pouring oil, be smoothly oil pot bearing ring or on the paper machine, roller and placed in the bottom of the oil pool, collecting flow hot oil, avoid wasting and burn; The operator should wear asbestos gloves, in order to prevent burns.
