subject: Understanding 6 Essential Principles Of Ball Screw Repair [print this page] All manner of high-tech industries are making use of ball screw technology. Ball screw components need to be regularly checked and repaired to ensure optimum performance and to troubleshoot failures, since these industries are technical in nature. The causes of failure may vary, but the essential principles for their repair do not. It is important to understand these principles to better know how ball screw repair is undertaken.
Using a lubricant
For your information, routine wear and poor surface finish are the usual factors that cause ball screw failure. This happens when the re-circulating ball screw surface is exposed to continuous contact with the hard surface of the ball screw shaft. Given enough time, the surface of the ball screw will succumb to wear and tear. The lubrication is present to both repair this specific problem and also helps the ball screw function correctly and make it last longer. However, it is important to select the lubricant that best suits the component's conditions. You should avoid over lubrication since too much grease can make more pressure to ball nut return system and cause the tube to burst.
Consider the condition of ball screw before beginning to repair
It is vital to scrutinize the initial condition of the ball screw before any changes are made. This principle includes checking the ball screw's free running condition and its drag torque. The main points that contribute to optimum ball screw performance will be the focus of the health check the ball screw is subjected to. This principle is necessary to determine whether the ball screw is still in repairable condition.
Extensive cleaning
Prior to repairing the ball screw component, it must be cleaned. Longitudinal course of the ball screw is initially rubbed and for clearing accrued oil and dust ultrasonic scrubbing and above-normal pressure cleansing is done on it.
Ball screw assembly rebuilding
Take note that micron-graded precision bearings which are extra large are recreated on the assembly of bsll screw. This is meant to achieve a satisfactory pre-load level that conforms to DIN specifications.
Prolonged testing
Ball screw units have to undergo extended examination. Ball screws are tested on motorized testing rigs to ensure the highest running performance possible. It will require thorough testing to figure out whether a ball screw meets the necessary standards and criteria. When the ball screw completes the testing and passes, an extensive test report is compiled and logged. Some of the details which should be included in the report are drag torque graphs and other essential data.
Refurbishing
You can use hard-chrome plating or metal spraying to refurbish bearing end journals. Using a precision universal grinder, they undergo regrinding after this. If needed, repairing thread forms are sometimes refurbished following a thorough checking and cleaning process. If required, cleaning and refurbishment of components like fixing key ways, wiper seals and other smaller details can be done.
The reality is that proper repair and maintenance of ball screw causes the device and operations become efficient and successful.
