ZYS clutch bearing avoid resonance with the host , avoiding sensitive resonance speed

In general , to control noise bearings must take countermeasures root causes for these noise generation , in order to receive a permanent cure results. The main route is :  (1) Choose low noise Cylindrical roller bearings ; (2) avoid resonance with the host , avoiding sensitive resonance speed ;  (3) from the cylindrical roller bearing applications link on trying to eliminate noise ;(4) is invalid in other ways , additional measures of noise and silencer . bearings when the temperature rises , first determine whether the malfunction, as indeed increased, should wheel bearing be treated as follows :  check the cooling water pressure , flow and piping systems are normal. If water filter may be clogged down and can not handle , you can stop treatment, when it is confirmed to work , and then put into use.  Should check governor oil pressure, oil pressure may result if the cooling water hydraulic valves closed.  Check whether there is abnormal sound ball bearings  bearings , cylindrical roller bearings and detect whether there are abnormal swing . Take oil samples to observe whether there are changes in oil color , and conduct tests to see whether the deterioration. If confirmed deterioration , should be shut down to replace with new oil. Check the oil standard oil level is normal, if abnormal , check the tank drain valve is closed. If closed, should fill the oil , if it is sealed cushion oil leakage should stop processing

No matter how high-performance ball bearing

Bearings are precision components , be careful when you need to use . No matter how high-performance  high speed bearing  , if used improperly , it will not get the expected performance . Here are some Precautions bearing. A keep clean environment in and around bearing invisible even fine dust into the bearing , will increase the wear , noise and vibration of the bearing. Cylindrical roller bearings and their peripheral accessories should be kept clean , especially dust and dirt , tools and work environment are essential to keep it clean . Second, when used carefully allowed to install a powerful punch , knocking allowed direct bearing with a hammer , are not allowed to pass through the rolling pressure . Third, the use of appropriate , proper installation tools possible to use special tools, such as heaters and special high precision bearings    drawing tool , etc., try to avoid using things fabric and staple fiber and the like . Fourth, to prevent corrosion of the bearings by hand directly when handling bearings, be sure to wash hands sweat , and coated with high-quality mineral oil before operation, especially during the rainy season and summer to pay attention to rust. However , in some special operating conditions , cylindrical roller bearings can get a longer life in traditional computing, especially in under light load conditions. These special operating premise is that when the rolling surface ( track and rolling elements ) are effectively separated and limit pollutants may cause damage to the surface of a lubricant film .

ZYS ball bearing With a high pressure oil pump through the nozzle hitting insert ball bearing

Oil lubrication method comprising :
1 drip lubrication
Drip lubrication oil rationing was needed for spherical roller thrust bearing components , usually every 3-8 seconds drip drop amount is appropriate , too much oil will cause bearing temperature increased.
2 cycle oil lubrication
The filtered oil pump feeding oil to the bearing member , through the bearing lubricant and then filtered after cooling to use. As the cycle oil can be taken away some heat , so cooling  insert ball bearing and therefore law applies to high speed bearing components.
3 oil bath lubrication
Oil bath lubrication is the most common method of lubrication , suitable for low- , medium-speed bearing lubrication , spherical roller thrust bearing part of the dip in the tank , oil from the rotation of the bearing parts brought up , and then back into the oil sump should be slightly lower than the center of the lowest rolling element .
4 jet lubrication
With a high pressure oil pump through the nozzle hitting the bearings , INA bearings in oil injected into the other end of the bearing into the tank through . When the Rolling mill bearing is rotating at high speed , the rolling body and the retainer are relatively high rotational speed of the surrounding air to form an air flow difficult with the general method of lubrication oil to the bearings , then the lubricant must be sprayed with high-pressure injection method to thrust spherical roller bearings , the position of the nozzle should be placed between the inner and maintaining aircraft center.
5 spray lubrication
With dry air formed by the spray mist mixed with oil , jet thrust spherical roller bearings, air bearings can effectively make INA cool and prevent intrusion of impurities . This method is suitable for high-speed, high-temperature lubrication of the bearing components.
