Miniature thrust groove sealed ball bearings

58 Published by admin Apr 11,2022

Miniature thrust groove sealed ball bearings are dynamic pressure bearings. To make the miniature thrust groove sealed ball bearings work normally, the following conditions should be met:  
1.  The lubricating oil has a viscosity;  
2.  There is a certain relative velocity between moving and stationary bodies;  
3.  Two surfaces in relative motion inclined to form an oil wedge;  
4.  The external load is within the prescribed range;  
5.  Enough oil.

Pay attention to the preceding requirements during installation and operation. Tile bearing miniature thrust groove sealed ball bearings is michelle type, each segment of the working face casting plastic metal layer, miniature thrust groove sealed ball bearings alloy layer thickness of 2.0 mm, there is a deviation on the back of tile symmetric center bearing steel as a result, under the action of a hydraulic tile around the miniature thrust groove sealed ball bearings steel swing tilt, thus formed between thrust disc and thrust segment cuneate gap, when the rotor rotates,  The oil is continuously fed into the wedge-shaped gap to form a dynamic pressure film with pressure resistance to balance the thrust of the turbine and transfer the thrust to the bearing seat.  
Due to the formation of oil film liquid lubrication, there is no metal friction between the thrust plate and the thrust tile during normal operation of the turbine.  

miniature thrust groove sealed ball bearings
Mainly used for insulation inspection, including thrust head and mirror plate, anti-weight block and upper frame, thrust head and rotor.  
Requirements for miniature thrust groove sealed ball bearings: insulation resistance not filled with oil ≥ 1M ω Insulation resistance after filling with oil ≥ 0.5M ω Insulation resistance after bearing ≥ 0.2M ω The role of insulation pad in miniature thrust groove sealed ball bearings has the following aspects:  
(1) Cut off the shaft current to prevent the lubricating oil film on the thrust tile surface from being damaged by the shaft current.  
(2) The thrust head can be connected more closely with the mirror plate.
