Universal reducer rated power is generally by the use of (case) coefficient KA = 1 (motor or steam turbine as the prime mover, smooth gear reducer maintenance work machine load, working 3 ~ 10h a day, ≤5 times the number of starts per hour, Shandong reducer service that allows starting torque to operating torque of 2 times), contact strength safety factor SH≈1, single failure probability of gears ≈1%, Tianjin reducer maintenance, and other conditions determined by the calculation. Selected reducer rated power should meet: PC = P2KAKSKR≤PN where PC --- computing power (KW); PN --- reducer rated power (KW); P2 --- working machine power (KW) ; KA --- factor, consider the impact of working conditions, see Table 1-1-6; KS --- start coefficient, consider the impact of start times, see Table 1-1-7; KR --- Reliability coefficient, taking into account different requirements for reliability, speed reducer repair program, see Table 1-18. Currently the world using the coefficient used basically the same. In the global economic slowdown in the growth environment, Siemens fiscal year 2012 (2011 10 1st - September 30, 2012) Performance in China is still close to record levels, further strengthened the value chain in the Chinese mainland, maintained a stable market position. "Our performance in the 2012 fiscal year close to record levels last fiscal year, which in the case of the macroeconomic slowdown achieve. For Siemens, it was a successful year." Siemens North East Asia CEO of Siemens (China) Co., Ltd. Mei-Wei Cheng, president and CEO, said, "In a situation unfavorable external economic environment, the steady development of Siemens China, the four business segments showed strong momentum."
