YRT rotary table bearings load accuracy

YRT rotary table bearings is a kind of high precision bearing which is commonly used.At the same time it is widely used in medical machinery, CNC machine tools and even precision radar and other high precision equipment.So, must be every moment keep rotary table bearings a good condition and use of performance, need to maintenance, repair, in order to prevent accident arrangement, to ensure reliability of the turntable bearings, improve productivity and economy.Maintain it is best to check regularly, FRB BEARINGS introduces some matters needing attention for the general customers.

The inspection of YRT rotary table bearings includes monitoring operation condition, adding or replacing lubricant, and regular disassembly inspection.As an overhaul in operation, there are YRT rotary table bearings rotation sound, vibration, temperature, grease status and so on.When removing the bearing for maintenance, first record the appearance of the bearing, confirm the residual amount of lubricant, after sampling the lubricant used for inspection, clean the bearing.

According to the load applied to the bearing of the turntable and the rotating condition of the ring, the load of the ring can be divided into fixed load, rotary load and swinging load.

1. The radial load generated by the fixed load is borne by the part of the raceway of the loop and is transmitted to the appropriate range of the shaft or shell.This load Swedish bearings become fixed bearing loads.The unique feature of the fixed load is that the combined radial load is relatively static with the sleeve.

2. Turn the load utility on the bearing ring of synthetic radial load vector along the circumferential direction, the progressive assumed by any part of the race, and accordingly the delivery to any part of the shaft casing hole appearance.This kind of load is called the reverse load, or cyclic load.

The unique aspect of the reverse load is the relative rotation of the synthetic radial load vector and the loop.A suitable clearance or overfill should be used for the collar, shaft or shell holes that bear the load of turning down.Synthesis of radial load acting on the bearing ring vector in the ring groove of a certain region within the scope of relatively rocking back and forth, for the race to a certain region, and hand in phase to pass to axis or a certain region of the shell hole appearance, or utility on the bearing load is impact load and vibration load, the load direction or figures often change, this load is called waggle load, and is not the direction of load.The inner and outer ring shall be deemed appropriate and used properly when bearing the load of swinging back and forth, especially when bearing the heavy load.When the inner ring rotates back and forth, it is generally considered appropriate for the inner ring to use the rotating load.

YRT rotary table bearings the negative clearance preloaded, can withstand the part of the bearing load, to avoid deformation seriously affect the accuracy of bearing load is too high, therefore, choose YRT rotary table bearings load demand, must tell manufacturer general bearing clearance adjusted when delivery from factory, can achieve the ideal effect.
