Yesterday afternoon, Guangdong Semiconductor Lighting Industry Joint Innovation Center held the 2013 China (Shenzhen) LED Industry Development Summit Forum in Shenzhen.
The forum released the Guangdong LED industry operation test report. The report shows that in the first half of this year, a total of 20 cities and towns in Guangdong released LED street lights and tunnel bidding information, totaling 272,700 baht, of which, in the first half of Shenzhen, tender LED street lights and tunnel lights were 28,500 baht. . From the perspective of corporate profits, nearly 80% of companies' earnings in the second quarter were flat or better than last quarter. In the first half of 2013, Guangdong's LED output value reached 1251 billion yuan, ranking first in the country. Shenzhen's industrial scale ranks first in the province, with an output value of 46.945 billion yuan. As of June this year, Shenzhen LED patent applications reached 17,373, accounting for about 40. The innovation capability of semiconductor lighting technology in China has been rapidly improved. The gap between technological innovation and international level in the industrial chain has gradually narrowed, and a number of outstanding LEDs have emerged. enterprise.
On the same day, the joint research base of Shenzhen University and Tongpu Technology was officially launched. The two sides will cooperate with schools and enterprises in the field of LED optoelectronic technology, carry out technical research and academic research, and carry out technological upgrading in LED packaging technology, heat dissipation and product materials, and accelerate technology. Transformation of results.
Driving & Driven Cylindrical Gear
Gear mechanism is used to transfer motion and power between two shafts,and is the most widely used transmission mechanism,It is through the meshing of gear teeth to achieve the transmission requirements,so compared with the friction wheel,pulley and other mechanical transmission,its remarkable characteristics are:stable transmission ratio,reliable work,high effciency,long life,suitable for a wide range of diameter,circumference speed and power.
Cylindrical gear is an important gear type in mechanical gear,but also the most common gear style.
Cylindrical gears accroding to the direction of the teeth,can be divided intospur cylindrical gears,helical
Cylindrical gears and herringbone cylindrical gears
