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.

The meeting first observed the scene of rice drying in the Shengsheng Grain Drying Center of the County Economic Development Zone. The person in charge of the drying has a strong sense of environmental protection. Under the guidance of relevant departments, the coal-fired furnace will be considered in the long run. Transformed into an air source electric heat pump, it became the first grain drying center in the county to use air source heat pump as a clean heat source. At the meeting, the technical personnel of the relevant manufacturers explained the technical advantages of the air source heat pump drying and answered the questions of some drying owners; the person in charge of the drying center of the Shengsheng introduced the input cost, production cost and usage of the air source heat pump. . At the promotion meeting, the heads of the three inspection teams of the county agricultural machinery bureau drying heat source reconstruction and the responsible persons of the agricultural technology centers of the townships and villages exchanged speeches on the transformation work; the person in charge of the Science and Technology Section of the County Agricultural Machinery Bureau reported the grain drying of the county. The progress of the renovation of the dry center and the specific assessment of the next assessment and acceptance work; the responsible person in charge of the county agricultural machinery bureau put forward three requirements for the next step of reform: First, unify thinking and raise awareness. The second is to focus on guidance and strengthen communication. The third is to clarify responsibilities and promote progress.
There are 101 grain drying centers in Baoying County, Jiangsu Province. Currently, there are 60 drying centers using clean heat sources, and 41 drying centers without clean heat sources. In order to implement the spirit of the relevant documents of the county government, speed up the renovation of the clean heat source of coal-fired grain drying ovens in the county, and ensure the complete renovation of the coal-fired grain drying ovens in the county before the end of the year. On November 7, the county agricultural machinery bureau in the county economy The development zone convened the county's coal-fired grain drying oven to clean the heat source to observe and promote the meeting. More than 50 people attended the meeting of the agricultural machinery in charge of the township, the unmodified drying owner, the county power supply company and the technicians of the grain drying and cleaning heat source manufacturers.
