ZEPTTstock bearing EPT rings slewing ring bearings 571.forty.1120 for renewable energies
Descrizione della merce
EPTnical prerequisite of Yaw and Pitch bearings for wind turbine:
1. EPT and heat remedy
Rolling elements in yaw and pitch bearing are made of GCr15 or GCr15SiMn bearing metal according to GB/T 18254 2002. The warmth remedy
of bearing steel ought to comply with JB/T1255-2001. Other components with equivalent or EPT performance can also be employed.
The substance of rings in yaw and pitch bearing normally use 42CrMo that comply with GB/T3571999 stXiHu (West EPT) Dis.Hu (West EPT) Dis.rds or other supplies which meet the
functionality demands. The reduced-temperature effect power prerequisite of the ring is -forty ordmCAKV, not significantly less than 27J.
The flaw detection of the ring of the yaw and pitch slewing bearing is not decrease than the amount II needs in the GB/T7736-2001 stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd. Right after quenching and tempering, the hardness of ring is 229HB 269HB or deterEPTd by negotiation between the supplier and
the customer. The quenching hardness of the raceway surface is 55EPTC-62EPTC.
The width of the soft belt of the yaw and pitch slewing bearing ought to not be better than the diameter of the plunger gap plus 35mm. The comfortable belt ought to EPTTly be put in the raceway situation of the plunger hole.
two. Ring EPT of the yaw and pitch slewing bearing
Ring EPT in the yaw and pitch slewing bearing is mainly involute cylindrical EPT with EPT radial modification coefficient X= .five. EPT module should meet the restrictions in GB/T1357-1987 stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd. The accuracy of EPT should not be lower than the demands of 998GK in GB/T10095.one-2001 rules.
3. Clearance
EPTTly the radial and aXiHu (West EPT) Dis.al clearance of yaw bearing is -50 mum, and the clearance can be altered according to the consumer specifications.
The radial and aXiHu (West EPT) Dis.al clearance of pitch bearing is reduce than .
four. Lubricating oil gap
The yaw bearing and pitch bearing are lubricated via lubricating oil hole, which is screw hole with the specification of M10 times1.
5. Seal
For the yaw bearing and pitch bearing in wind turbines, the seal EPTTly use NRB substance which comply with HG/T2811-1996. ZYS makes use of the sealing ring of effectively-known overseas manufacturers with very good functionality and dependable high quality for our yaw bearing and pitch bearing.
Since the wind turbine is uncovered to the wild, there are stringent demands on the sealing functionality of the yaw bearing and pitch bearing, and the seal type of the bearing need to be optimized to guarantee that the bearing daily life is the same as the wind turbine. Wind turbine are set up at an altitude of far more than 50m or even hundreds of meters, and the EPT of assembly and disassembly is costly. Therefore, they should have quite high trustworthiness. EPTTly, they need twenty several years of lifestyle. In addition, the bearing framework is challenging, so the needs for design and style and manufacture of yaw bearing and pitch bearing are extremely high.
6. Spacer and cage
ZYS yaw bearing for wind turbines has spacers that are self-lubricated and can compensate for lubrication when lubrication oil is inconsistently
dispersed in order to keep best lubrication status in between balls and groove contact locations.
ZYS pitch bearing for wind turbines utilizes built-in steel cage which has basic framework and can preserve room. It also can accommodate far more balls
to enhance load potential. In comparison with classic segmEPTTd cage, built-in cage is less complicated to assemble and more secure and trustworthy throughout
operation.
seven. Preservative treatment method
For the yaw bearing and pitch bearing, all surfaces except the groove and EPT need to be applied thermal spraying anti-corrosion treatment in accordance to the restrictions in GB/T9793-1997 and GB/T8427-1996. When applied zinc coating, the thickness of anti-corrosion layer shall be no considerably less than a hundred and sixty mum. Other anti-corrosion remedy can be utilized to meet the overall performance requirements of the EPTT.
