Slewing bearing downstream industrial agglomeration and development in Ningxia

According to Mr. Li Shuming Northwest bearing , general manager of introduction, Northwest Bearing developed "2.5MW wind power generation equipment spindle bearings " project, designed to meet the requirements of the user MWT-2500A (2.5MW) direct drive wind turbines. Can not only improve the company's own income , but also effectively promote Roller Bearing the local wind power equipment, downstream industrial agglomeration and development in Ningxia , and promote the formation of the wind power industry development and industry chain , has far-reaching implications for Ningxia industrial restructuring, transformation of economic growth mode ; company developed the " heavy-duty vehicle nose cone bearing " project, in addition to improving the company's revenue , but also by dump truck with a nose cone clutch bearings  development, open -highway heavy-duty dump truck bearings supporting the localization market ; company developed " Metro ( light rail ) development and application of bearings " project , if successfully implemented, can promote China's subway cars bearing domestic work , breaking the monopoly of foreign technology , reduce procurement costs and improve the ability to self- repair , revitalize national industry, to promote the development of China's rail transportation equipment manufacturing and upgrades.
Insiders said that before the 1990s, Northwest bearing bearing industry has been one of the national key enterprises , the scale of production in the fourth digit industry

Have a conical taper roller bearing inner ring and outer ring raceway

Tapered roller bearing mainly bear radial primarily diameter, the axial load. Bearing capacity depends on the Angle of the outer ring raceway, the greater the Angle, the greater the carrying capacity. The separated type bearing is a bearing, according to the Slewing bearing the number of columns of the scroll body can be divided into single row, double row and four row circular cone roller bearings. Single row tapered roller bearing clearance to users in the installation adjustment; Double row and four row circular cone roller bearings clearance has according to user requirements for a given when the products leave the factory, not the user.
Have a conical taper roller Rolling mill bearing inner ring and outer ring raceway, the tapered roller are arranged in between. All projection line on the surface of the cone axis bearing the same points together. This design make the taper roller bearing is especially suitable for composite (radial and axial load. Bearing axial load capacity is mostly determined by the contact Angle alpha; Alpha Angle is larger, the higher axial load capacity. Angle size by calculating coefficient of e; E value, the greater the contact Angle, the greater the bearing axial load of the greater applicability.

Slewing bearing with excellent impact resistance

With appropriate hardening depth , meticulous organization , appropriate surface hardness and core hardness of infiltration of carbon bearings , thrust bearing steel than using spherical roller bearings with excellent impact resistance , the general chemical infiltration of carbon bearing steel ingredients. <BR> Punched retainer material , the use of low high precision bearings carbon steel. Depending on the application , use brass, stainless steel plate. Cutting cage material , the use of high strength brass, carbon steel , in addition, also the use of synthetic <BR> thrust spherical roller bearings are generally manufactured through forging , heat treatment, turning, grinding and assembly of multi-channel processing processes. The reasonableness of the processing technology , advanced, will also affect the stability of the bearing life . Which affect the quality of the finished gimbal Rolling mill bearings heat treatment and grinding processes, tend to have a more direct relationship with the failure of the bearing. Recent studies of spherical roller thrust bearing surface modification layer showed a close bearing surface grinding process and quality . <BR> Spherical roller thrust bearing life analysis of the main tasks is based on a lot of background material , analysis of data and failure modes , identify the main factors that cause bearing failure , so that puts forward improvements to extend bearing service period , to avoid spherical roller thrust bearings early occurrence of sudden failure

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

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 .
