We know that the majority of bearings under normal circumstances after the damage to be replaced, but for some NSK Bearings, repair it if the cost is not high, we will choose to repair the bearings.
Datum transformations composition repair method
Sometimes the design basis deformation is too large to use, we must choose some other side as a reference, while the size of a chain re-integration. For example, if the NSK bearing deformation is too large, it should be the basis of the rotary assembly, rework correction bearing body, then press out the reworked bearing body size, adjust the assembly dimension chain, the method of repair adjustment ring, according to the size of the chain detection and repair of the order, the last of the closed loop control accuracy.
Benchmark unchanged combination repair method
When resizing and repair chain accuracy, based on the reference coincidence principle, only use a plane as a reference, namely the design basis, while all other repairs are acting surface as a reference surface. This combination repair reference for inspection accuracy, reduce the accumulation of errors. For example, the governor hydraulic coupling repair, often bearing body as a reference.
1. suitable viscosity and good viscosity-temperature characteristics
For the spindle temperature will not be too high and the machine thermal variations, or to affect the machining accuracy NSK bearings poor lubrication, it should be based on the structure of the spindle bearings, speed and bearing clearance and other selected appropriate temperature and oil required to have a good viscosity-temperature characteristics, and prevent the spindle temperature and ambient temperature change is large, the change in viscosity is too large to affect its lubricating properties.
2. Good lubrication
To make the contact surface between the shaft and the bearing to maintain a uniform film, and when the spindle start or stop motion film to produce an impact load is not caused by sabotage, to maintain good lubricating properties to reduce friction and friction plays a hot, reduce the spindle temperature, guarantee the role of precision, requires a good lubricating properties.
3. good resistance to oxidation
Spindle when the cyclical lubrication, NSK spindle bearing oil requires long-term use without deterioration so requires a good oxidation resistance.
4. Good anti-rust
Since the spindle oil lubrication system work process will inevitably mixed with the air condensing water or machine coolant, thus requiring oil has good corrosion resistance.
