The effect of CEMA idler lubrication on maintenance
Clicks:3366 Date:12-15
Lubrication has an important impact on the fatigue life of rolling CEMA idler and friction, wear, temperature, vibration and so on. Without normal lubrication, CEMA idler can not work. The analysis of the damage to CEMA idler shows that about 40% of the damage to CEMA idler is related to poor lubrication. Therefore, good lubrication of CEMA idler is an effective measure to reduce the friction and wear of CEMA idler. Besides, the lubrication of CEMA idler also has many functions, such as heat dissipation, rust prevention, sealing, mitigation and impact. The role of CEMA idler lubrication can be briefly described as follows:
A. forms a layer of oil film between the two rolling surfaces or sliding surfaces to separate the two surface to reduce friction and wear on the contact surface.
When B. is lubricated by oil, especially by circulating oil lubrication, oil mist lubrication and fuel injection lubrication, the lubricating oil can take away most of the friction heat inside CEMA idler and play an effective cooling role.
When the C. uses grease lubrication, it can prevent the external dust and other foreign bodies from entering the CEMA idler, which can play a close role.
D. lubricants have the effect of preventing metal corrosion.
E. prolongs the fatigue life of CEMA idler.
When repairing and adjusting the dimension chain accuracy, according to the principle of datum coincidence, only one datum plane is used as the benchmark, that is, the design datum, and all the other surface repairs are based on this surface. This combination repair datum is easy to check precision and reduce accumulation error. For example, in the repair of a speed hydraulic coupler, the CEMA idler body is often used as a reference.
1. suitable viscosity and good viscosity temperature characteristics
In order to make the spindle temperature not too high and the machine tool thermal deformation, affect the machining accuracy or bad lubrication should be based on CEMA idler, CEMA idler, the structure of lubricating oil spindle speed and CEMA idler clearance suitable temperature and has good viscosity temperature characteristic, prevent spindle working temperature and ambient temperature change when the change of viscosity is too large to affect the lubrication performance.
2. good lubricity
In order to make the contact surface between the main spindle and CEMA idler maintain a uniform oil film, but also in the spindle start or stop motion impact load oil film will not damage, maintain good lubrication performance has reduced friction and frictional heat, reduce the spindle temperature rise, ensure the machining accuracy for requirements has good lubricating performance the.
3. good antioxidation
When the spindle of machine tool is used for circulating lubrication, the main shaft CEMA idler oil is used for a long time without deterioration, so it requires good oxidation resistance.
4. good rust resistance
Because the oil will inevitably be mixed into the condensed water or coolant of the machine in the working process of the main shaft lubrication system, it is required that the oil has good rust resistance.
