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 taper roller bearing crane maintenance operation 50 hours lubricated once

maintenance crane technology shift tooth surface work 10 once the debris should be removed and re- coated with grease.
 In order to ensure crane maintenance technical reliability of the bolt work to avoid bolt preload is insufficient, slewing the first 100 hours of work and 500 hours , respectively crane ZYS Precision Bearings maintenance should check pretension bolts . Then every 1000 hours of operation should be checked once pretension .
technology to connect maintenance crane slewing ring bolts and nuts are made of high-strength bolts and nuts ; double nuts and lock .
crane maintenance techniques tighten the nut should topcoat oil and nut threaded end of the bolt , and a torque wrench should be used uniformly in the circumferential direction ZYS taper roller bearings of symmetry repeatedly tightened. Crane Maintenance Technical finally tightened again when the crane maintenance techniques on each bolt tightening torque should be roughly uniform.
 crane maintenance technology in the slewing ring gear surface raceway parts are aligned cloth 4 cup oil , thereby adding grease to the Raceway . Under normal circumstances , slewing crane maintenance operation 50 hours lubricated once. Every crane maintenance techniques must add a little oil until the oil leaking from the seal so far .
