On October 30th, the reporter saw in the workshop of Samsung Precision Forging Gear Co., Ltd. in Qingdao, Shandong, that the workers performed a piece of product with good results. “The aftermarket precision forged gears produced by our construction machinery products set a record of more than 30 million units in monthly sales.†Xu Hongtao, director of the company’s office, told reporters, “The company's orders did not change during the busy season, and each production workshop took place in winter. It is changing from single shift to double shift."
Qingdao Samsung Precision Forging Gear Factory is the earliest enterprise involved in the auto parts industry in China. There are nearly 300 varieties of “Samui Brand†precision forging gears, covering more than 100 models. There are more than 180 domestic matching customers throughout the country. 28 provinces and cities.
It is not just Samsung that orders are busy and business is hot. Qingdao Zhangshi Machinery, a company specializing in the production of automobile piston rods, will have sales of 80 million units this year and an output value of 120 million yuan. The products will account for 70% of the domestic market share. Zhang Maoyin, head of the company, told the reporter that the company has recently established a new plant with an investment of 200 million yuan. Famous automakers such as BMW, Audi, and Volkswagen have used the parts and components produced by their companies and their products are in short supply.
Feng Qingcai, secretary general of the Jiaozhou Auto Parts Industry Association, told reporters that there are currently more than 100 auto parts companies in Jiaozhou, and the output value of each company is over 100 million yuan. Today, in Jiaozhou, the auto parts industry chain with more than 10 billion yuan worth of sales has been formed out of small parts. From screws to gears, from wipers to seals, from cars to trucks, a reasonable industrial chain of division of labor is gradually formed.
The USD 600 million Brazilian WHB auto parts project to be signed up and put into production will further promote the upgrade of the auto parts industry in Jiaozhou. It is understood that the company settled in Jiaozhou, the main production of differential box, speed box, bearing engine and other products, mainly for the German Volkswagen, Italy Fiat, the United States and other world-renowned car companies supporting.
With the increasingly perfect industrial chain, many companies have tightened the R&D clockwork and actively developed new markets. Take Qingdao Samsung Co., Ltd. as an example. Since May 2000, the company has invested heavily in product research and development. The national share of precision forging construction machinery differential bevel gears is about 70%, and three weeks of self-development and production Forging bevel gear is a domestic original, all exported to the United States.
In order to boost the development of the auto parts industry, Jiaozhou City has issued a number of incentive policies to provide more preferential treatment to the auto parts industry in terms of audit registration, credit, and information technology. At the same time, a special enterprise development fund of RMB 100 million will be set up to encourage enterprises to transform, upgrade and technologically innovate, and actively guide the industry associations to explore capitalized operations.
The function of the Universal Shaft Assembly is to convert planetary motion into fixed constant rotation of the drive shaft, to transmit torque and speed from motor on the drive shaft, and to the bit. Cardan shaft mostly uses flat shaft, but some are flexible shafts. Out flat type shaft used on out downhole motor is made by linear cutting technology. So the cut has high parallelism, roughness can reach 6.3 and it doesn't damage metal chemical composition. Thus, is has a longer running life and less mechanical loss.
Downhole motor shall be disassembled as quickly as possible after use to examine cardan shaft. If it is found out that wear degree is over maintenance standard, relevant consumable components shall be changed promptly. If not, downhole motor can not be running normally due to overrun of the cardan shaft.
