The wall thickness varies greatly, and the chamfer is of course eccentric. It is necessary to calibrate the tool, use a clean sleeve and use a suction meter. Just measure the deviation and correct it.
Within 5 wires, the wall thickness difference is about 8 wires, so the chamfering will not be too biased, mainly because the tooling installation is not in place. If the bearing ellipse is large, it is a little off-center.
Rolling integral eccentric bearing is a precision part, so it needs to be used carefully. Even if the high-performance integral eccentric bearing is not used properly, the expected performance effect can not be achieved. Therefore, when using integral eccentric bearings, the following items should be paid attention to:
(1), keep the integral eccentric bearing and its surrounding environment clean. Even if invisible smile dust enters the integral eccentric bearing, it will increase the wear, vibration and noise of the integral eccentric bearing.
(2) Be careful when using and installing. Hard punches are not allowed. It is not allowed to directly hit the integral eccentric bearing with a hammer. It is not allowed to transmit pressure through rolling elements.
(3) Use appropriate and accurate installation tools, try to use special tools, and try to avoid using things like cloth and short fibers.
(4) In order to prevent the corrosion of the integral eccentric bearing, when taking the integral eccentric bearing directly by hand, the sweat on the hand should be fully washed away before operation and coated with high-quality mineral oil, and special attention should be paid to rust prevention in rainy season and summer.
