Beijing Wind Energy Conference, SKF three new cheer

  Beijing SKF taper roller bearing Sales Center, Beijing International Wind Energy Conference in China terrestrial million kilowatts of wind power base construction of large-scale expansion and officially launched the construction of offshore wind power held against the backdrop of large, causing great concern in the global wind energy sector. Swedish group SKF Bearing supplier (SKF) to bring its quiet operation of wind turbine bearing, separable high angular contact ball bearing cylindrical roller bearings and WindLub centralized automatic lubrication system unveiled three new New Year Beijing International Wind Energy Conference.
 SKF bearings distributor in China, according to the relevant person in charge, the launch of three new products, is based on the market for new concepts and new technologies continue to research and development requirements. Wind energy sector, SKF has excellent design and manufacturing capability to provide a package for partners to wind energy solutions. SKF is committed to the world's leading knowledge and experience and superior technology implementation capacity and Chinese market share, for the Chinese wind power industry development and make unremitting efforts.
Beijing SKF bearings sales center, to introduce three new SKF Group show:
 SKF bearing mute: Noise High wind turbine technology has been one of the problems, which, SKF developed a new wind turbine specifications Silent bearings, the generator with a more optimized environment adaptability, and can run in a variety of situations to maintain sustained silent running. According to SKF China Ltd personnel, the new Silent bearings can be interchangeable with existing conventional bearings, without changing application design parameters can be used.

Dynamic test method

Spindle rotation accuracy of the measurement method, there are direct and indirect measurement measurements (specimen France) two categories, which have a direct measurement of static and dynamic measurements in two ways.
Static test method
Insert the spindle taper hole precision of the test rod, test bars in contact with the surface of the scale and face, gently rotating spindle measurements at different angles on the readings. Advantages: measuring method is simple, easy to operate, it can be tested with the rotary spindle taper hole centerline centerline are concentric; Disadvantages: does not reflect the actual operating speed spindle error motion, and does not reflect the movement may cause processing errors form error and the surface roughness.
Dynamic test method
Eccentrically mounted on standard test bars, in two mutually perpendicular radial fixed displacement sensor, and then install a vertical axial direction, the other displacement sensor, the signal input to the oscilloscope via an amplifier to measure the direction of rotation of the spindle error motion sensitive.
Motion error Figure Glossary
Total error motion (Total Error Motion) - more than enough laps to record all errors polar plots, which represents the main average error motion (Average Error Motion) - is the total error motion polar plot of the average contour, on behalf of the aircraft station ideal cutting conditions can best machined parts roundness. Random error taper roller bearing (Asynchronous Error Motion) - is the total error of the mean error motion movement deviation, which represents the ideal cutting conditions can obtain surface roughness.
Basic error (Fundamental Error) - The average error motion of the closest circle, on behalf of spindle axis once per revolution axial errors.
Residual error (Residual Error) - The average error motion picture of the basic error of the deviation, on behalf of the plane of the end face machining

The domestic production of slewing sensing device

Saet induction heating equipment produced by slewing bearing products around the world have the majority of wind power plants in harsh environments, has withstood more than 20 years of continuous operation test of the actual operation, the wind power industry is widely recognized. The domestic production of slewing sensing device, no more than 20 years through the trouble-free operation of the actual test.
Saet is a company with 46 years experience in the production of induction heating equipment company, is the first research and development of wind power slewing sensing equipment of the enterprises. So far, Saet company has been able to provide a full range of slewing device, a total of three major series machine solutions, covering all the major taper roller bearing quenching needs. In Europe and other developed countries markets, Saet slewing ring sensing devices account for a large proportion. For example Saet company 8m large slewing quenching equipment now completed delivery seven.
In the high-end sensing device research and development, Saet company make full use of advanced computer simulation induction heating technology, relying on induction heating National Laboratory technical strength, continue to introduce new products and new technology. Recently, Saet company's proposed no soft belt roller quenching technology, as well as a large ring gear quenching (diameter 2.4m), reflecting the saet in induction heating equipment in the lead position.
Over the years, Saet company has been committed to providing customers with innovative solutions, through the use of simulation tools to explore the demonstration program, as well as to determine the exact cost of the equipment to continue to meet customer needs, so also won numerous world customers. Currently, in China, Saet induction heating equipment in Xuzhou Rothe Erde Slewing Bearing Co., Ltd. radius of bearing, Defeng Dan Co., Ltd. slewing processing enterprises have been successfully applied
