to control noise Slewing bearing must take countermeasures root causes for these noise generation

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 Sealed bearing measures of noise and silencer .  bearings when the temperature rises , first determine whether the malfunction, as indeed increased, should be treated as follows :  check the cooling water pressure , flow and piping systems are normal. If water filter may be clogged down high speed bearing and can not handle , you can stop treatment, when it is confirmed to work , and then put into use. hould check governor oil pressure, oil pressure may result if the cooling water hydraulic valves closed.  Check whether there is abnormal sound  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

Merchants under the land area yesterday news came

Merchants under the land area yesterday news came , people of China's largest bearing manufacturers , one of the Group , plans to invest 370 million yuan annual output of 2 million sets of heavy machinery bearing items. After completion, the land will become the central region next largest production bases of precision bearings approvals .

The project is located under the land area Tan Hill Rd overpass magnetic northern entrance , the land area of ​​120 acres , the project carried out there is a matching provincial spherical zys sealed bearing roller bearing technology center. After the completion of the project is expected to achieve annual GDP of 400 million yuan , 30 million yuan of tax and job placement staff of 400 people .
In addition, a total investment of 220 million yuan of annual output of 18 million sets of automotive wheel bearings precision CNC machining projects , land leveling has been completed , geological exploration and land delisting work . The project will zys aviation bearing adopt the most advanced automatic CNC lathe precision machining to achieve the type of car wheel bearing unit diversification , stable mass production .

In recent years , one of the Group through acquisitions , investment and technological upgrading , etc., who have been the next Lu Jianli Yellowstone Yellowstone Hart Bell Bearing Co., Ltd. and Precision Forging Co., Ltd. , the investment is expected to be the biggest fight in Yellowstone one of spherical roller bearings production base, and to the city's machinery manufacturing industry chain has been further extended .

Structural Classification of ZYS Slewing bearing

Wheel bearings ( wheel bearings ) , also known as slewing ring , is a way to withstand the large special structure of large axial load, radial load and overturning moment consolidated load bearing . Typically , with its own mounting holes , lubricants holes and sealing devices , to meet the different needs of a variety of different conditions ZYS precision bearing of various types of host. Turntable bearing itself has a compact, easy to guide rotation , easy to install and easy to maintain.
Structural Classification of wheel bearings
Turntable bearing structures commonly used form of a single row, double row four point contact ball slewing bearings, double row angular contact thrust ball bearing turntable , Cross cylindrical roller and cross tapered roller wheel bearings, ZYS taper roller bearings   ball column hybrid wheel bearings of different structural forms . Bearing in accordance with the above types of distribution sites and whether toothed gears are divided into different structures no gear, external gear , and the gear and so on.
Bearing turntable bearing characteristics
Wheel bearings can satisfy the needs of working under various load conditions , depending on a host of structural features . Among them, four-point contact ball slewing bearings with high dynamic load capacity. Double row ball slewing bearing capacity than a single volleyball turntable has greatly improved. Cross cylindrical roller slewing with high static load capacity. Ball joint wheel bearing pillar in ensuring the accuracy of certain rotating conditions, with large axial and radial loads and the ability to overturning moment .
