Rotary bearing is a kind of large special structure bearing which can bear large axial load, radial load and overturning moment simultaneously. Usually, it has installation holes, lubricating oil holes and sealing devices, which can meet the different needs of all kinds of hosts under different working conditions. In addition, the rotary bearing itself has the characteristics of compact structure, convenient guide rotation, easy installation and easy maintenance.
Application one, rust prevention
Special coatings can preserve the performance of bearings. Chromium (TDC) or nickel plating are commonly used to prevent rust, although the outer surfaces are coated with special paints or oxidized to provide long durability.
Application two, lubrication and sealing
Most bearing failures are caused by improper lubrication or contamination of impurities. Grease spills are acceptable in many construction equipment (with or without seals), but in other applications, such as robots, locators, and controls. Grease leakage is not allowed. In many applications, grease leakage can affect product quality and cause safety problems.
Application three, ball and roller isolation block
The rolling bodies are usually separated by separate blocks. This structure can maintain the stability of motion, so it is widely used. Special ball or roller isolation blocks are required for special applications. For bearings installed on the horizontal shaft or continuously rotating generators and bearings used in high requirements for positioning and reliability, strip combined cage can be used to make the rolling body in the correct circumferential position.
Application four, gear
In many cases, teeth can be machined on the inner or outer ring of the bearing to simplify the structure of the drive system. To avoid problems, seek the help of gear experts when determining drive system structure.
Application five, the choice of connection mode
Bolts are mainly used to connect the turntable bearing with the frame and rotating parts. Therefore, the number of bolts, diameter, length, accuracy, especially installation is very important. Not only is the bolt arrangement different for different applications, but the inner and outer rings are also different
