Other thrust rolling bearing structures
Bearing structure for a domestic LC type vertical long shaft pump,
The structure of a TC type vertical single-stage single suction cantilever submerged pump in China is equivalent to that of a horizontal single-stage single suction cantilever bearing structure.
Lubrication of thrust rolling bearing
Dry oil lubrication Grease filling cup, ZN-3 sodium base grease or lithium base grease is recommended
Immersion thin oil lubrication Immersion thin oil lubrication is shown in. For vertical pumps, the rolling element shall be immersed to a certain depth, and it is better to immerse 2/3 of the ball.
Self circulating thin oil lubrication.
When the shaft rotates, a bowl at the lower part of the rolling bearing sleeve rotates with it, forcing the oil subjected to centrifugal force into 6-8 oil holes), rising above the rolling bearing, and then returning to the oil pool at the bottom of the bearing body after passing through the rolling bearing. The circulation of lubricating oil not only makes the rolling bearing lubricated, but also cools the lubricating oil
But. If necessary, the oil pool can be cooled by adding a serpentine tube (see Figure 55) or by adding a cooling water jacket to the oil pool.
(4) The lubricating oil level shall be displayed by oil cup or oil pointer. The upper part of the thin oil lubricated bearing body shall be provided with a vent plug, and the bottom shall be provided with an oil drain plug.
(5) The thrust sliding bearing at the end of vertical pump is not introduced here because it is rarely used and complicated. At this time, the motor is often allowed to bear the axial force and the mass of the pump rotor.
当轴旋转时，滚动轴承套下部有个碗形 也随着旋转，迫使受离心力的油进人油孔一般6-8个) 并上升到滚动轴承上方，然后经过滚动轴承后返回到轴承体底部的油池中。润滑油循环，不仅使滚动轴承得到润滑，而且润滑油同时也被冷
