Although he left the army, but traces of camp life or branded deep in the body of Li Yue, feisty temper let him buy a car in the car when the election would choose their most over the letter Aowei engine --- . I gave my back to my brother during training, and I gave everything to it during transportation. Li Yue told the China Truck Network reporter that the new car he bought last year was loaded with the Aowei engine of FAW Jiefang Xichai. When asked why he chose the Aowei engine, Li Yue said: "The most fearful thing about running long distances is that we are thrown on the road. I used to know the power of the Xichai engine when I was running long distance with my friends. I have been doing very well, the famous brand, I can trust it. The Xichai engine that created 2 million kilometers without major repairs benefited from the careful and thoughtful service of Xichai, as the creator of the 2 million-kilometer miracle of the Aowei engine. I don't choose who he chooses?" Li Yue told reporters personally: "The family is not assured that I am running long distances alone. So last year I changed the new car. It was like the daily training of Yanji when I was in the Air Force. At that time, we were a group of two people who could put the back. Give the other person's life and death brother. Now it is the same, I am on time to maintain, five oils and three water and wearing parts I have always used the best, every time you have to check carefully before leaving the car. It has never left me On the road. We have a tacit understanding, like a brother." Saving fuel is not accidental but technology makes When asked by reporters about fuel consumption, Li Yue said with a smile: "I haven't figured out it because I have been running the Yangtze River Delta all the year round. I am familiar with the road conditions. I am taking the near road that I have summed up. Try not to go high speed, high speed to charge, but overall it can still feel that Xichai's engine is the most fuel efficient." In fact, the fuel economy of the Xichai engine has long been conclusive in the industry. According to experts, the self-developed Xichai Aowei engine uses lightweight design, low-particle distributed combustion system with effective thermal efficiency of 45%, dedicated cam compression engine brake system, 100,000 km engine oil replacement technology, 1.5 million km B10 Eight innovative technologies, including life reliability technology, common rail fuel injection system electronic control unit (ECU) and gas flooding urea injection system. While the products have reached the national five emission standards, they have solved key technical problems such as low fuel consumption, long life and long oil change intervals, and obtained 6 inventions and 36 utility model patents, filling a number of technical blanks for domestic heavy diesel engines. It adopts overhead camshaft technology, combined with four-valve technology, higher efficiency of intake and exhaust, more punctual ignition, more complete combustion, 5%-8% fuel saving than similar products; technology-leading innovative technology has become a sought-after customer An important factor in the Aowei machine. As a person who came over, Li Yue and the Chinese truck network reporter talked about a lot of things in long-distance transportation. From his words, we can feel his enthusiasm for the satisfaction of Xichai engine and life, watching Li Yue and his "brothers" start again, and sincerely wish him a good trip!
The guide wheel is the reaction element of the hydraulic torque converter, which is fixed on the guide wheel shaft or guide wheel sleeve in one direction through the one-way clutch. A pulley used to guide the drive belt through obstacles or to change the direction of the drive belt, which is located between the turbine and the pump wheel.
Guide wheel system is one of the key components of multi wire cutting machine, which undertakes the transmission of metal wire. Its rotation flexibility, end jump and diameter jump are very important to the reliability of the whole equipment. This paper studies the structure of the whole guide wheel system from the design point of view, designs the guide wheel shaft, calculates and analyzes the service life of the whole guide wheel system, and finally meets the requirements of the equipment.

Xichai Aowei engine
Working principle and structure design
The guide wheel system is responsible for the transmission and direction change of the metal wire of the multi wire cutting machine. The maximum linear speed of the multi wire cutting machine is 680 M / min, and the corresponding guide wheel speed is nearly 3000 R / min, which requires the guide wheel system to rotate at high speed, with flexible rotation, small runout, high reliability and long service life, so as to ensure the stability of the metal wire tension and the overall reliability of the equipment. At the same time, the guide wheel system is all on the side of the receiving and setting out box, which is in a dirty working environment. Mortar fluid will inevitably stick to the guide wheel. In order to ensure the flexibility of the guide wheel rotation, the sealing device must be designed for the guide wheel
The whole guide wheel system is mainly composed of spacer sleeve, guide wheel shaft, guide wheel, gland, bearing and other components. The guide wheel is the embodiment of the final accuracy of the whole system. The metal wire moves at a high speed in the guide wheel groove to drive the guide wheel system to move at a high speed. The rotation accuracy of the guide wheel reflects the accuracy of the whole system. Therefore, the whole system must ensure the rotation accuracy after the guide wheel is installed, i.e. rotation flexibility, end jump and diameter jump accuracy, The high-precision angular contact ball bearing used back-to-back ensures the rotation accuracy of the guide wheel system, which has high precision, long service life and small end jump and diameter jump[ 1]
Life calculation of guide wheel system
The structure of the guide wheel system is analyzed. The guide wheel is a vulnerable part and must be replaced after working for a certain time. In order to facilitate disassembly, the corresponding structure is also designed. The service life of the guide wheel cannot be used as an indicator of the service life of the whole guide wheel system, so its service life mainly depends on the service life of the selected high-speed rotating bearing. In order to meet the requirements of high speed and high precision of the guide wheel system, high-quality angular contact ball bearings are selected for back-to-back installation[ 1]
Effect test
Through the experimental application in multi wire cutting machine, the guide wheel system has the characteristics of flexible rotation, high precision, good sealing effect and low failure rate.
On the way from Hangzhou to Zhejiang Xianju, Li Yue accepted an interview with a Chinese truck reporter. From his unusual behavior, the reporter further learned that Li Yue had had the experience of being a soldier. At the age of 19, he entered the military camp. After he was 21 years old, he plunged into the ranks of long-distance transportation. It has been 15 years since then.
