Q:Our factory production of gears running noise, want to solve through the grinding method, seeking expert guidance. Question added: We used this method, because we buy grinding machine financial capacity is not realistic, and occasionally heard the gear grinding the processing method, they have tried, is to match the two gears to exert a certain pressure on the grinding sand bite A few minutes, after the experiment found to be able to improve some, but now our process is not good to control the angle of the helical gear, seeking expert detailed instructions, or what better way to solve our helical gear noise problem? More

I did for 20 years, do not know the gear can also be grinding. In order to reduce the noise 1 by grinding method, you can achieve 5 precision 2 with quilting teeth approach, you can achieve 6 precision 3 high-speed occasions, the method can be coated on the tooth surface to reduce the noise to solve the problem 1 teeth Good shape 2 teeth to better 3 surface roughness is better

Q:In the airport shopping mall and other public places up and down the stairs or escalators should rely on what to stand?

Some people say that the right, it was said to the left. A professional escalator engineer will tell you that the middle of the station. why? First, the user long-term left or right, will make the escalator long-term pressure, the side of the parts of the high frequency of damage, shorten the life of the escalator. Second, we rely on the side of the station, leaving the other side, is implied to let others walk from the gap. To know that the escalator is automatic, you use it to ask you to obediently stood. Please take the ordinary stairs to go. Or you go anxious, met someone else, we fell, and on both lose, haste not up to.

Q:My model: hippocampus Fumei to transmission: manual Displacement: 1.6 l Driving range: 2200 km Time of purchase: September 2017 Problem Description: Ask the experts advise on the three generations of the first solution of the United States to the oil 4S there are two kinds of oil, one is mineral Oil 10W-30 The other is semi-synthetic 5W forged teeth forged forging feathers Quan Chuan Huowen these two are SL level. Compare the favorite Castrol's EDGE5W-304 lift. Other do not know. In fact, they also know that economic cars do not need to use a good oil, but still want to own the first car a little better ~ by the way here we winter temperature is generally not lower than minus 25 degrees. Road more urban areas, and occasionally run suburban road. Seek expert advice ~! More

Or recommend the use of good oil, although you said the economic car do not use so good oil. But in fact the individual is not the same good oil first good performance, clean ability, reduce sludge carbon deposition, the engine protection will be better, and the whole synthetic oil, then the general is about 8000 for a change, the ordinary oil on 5000 or so, in fact, Count down the words, but also how much money! Like me, now with the ERG full synthetic cramps forged forging the feat boxing hides the oil, it is also good, cost is also high, or more recommended! Castrol's guard is also good, but the premise to ensure that genuine. Or to buy fake oil on the trouble!

Q:Hitachi Elevator out of the 61 with the door of the lock after the opening of the arrow outside the instructions to flash how to repair

May be caused by the connection of the motherboard. May be caused by damage to the internal parts of the machine. It is recommended to contact the maintenance staff can be repaired. An elevator is a motor-powered vertical lift with box-like pods for multi-storey construction or cargo. There are steps, stepping board mounted on the track for continuous operation, commonly known as escalators or automatic sidewalks. Serving the floor of the fixed lifting equipment. The vertical lift elevator has a car running between at least two rows of rigid or inclined rails with an inclination angle less than 15 °. Car size and structure to facilitate the passengers access to or loading and unloading of goods. It is customary to use the elevator as a general term for vertical traffic in a building, regardless of the way it is driven. According to the speed can be divided into low-speed elevators (1 m / s below), fast elevators (1 ~ 2 m / s) and high-speed elevators (2 m / s or more). The mid-19th century began to appear hydraulic elevator, is still in the low-rise buildings on the application. In 1852, the United States E.G. Otis developed a wire rope lift safety lift. 80 years, the drive device to further improve, such as the motor drive through the worm drive winding reel, the use of balance weight and so on. At the end of the 19th century, the use of friction wheel drive, greatly enhance the lift height of the elevator.

Q:Grocery elevator is always automatically anti-leveling what is the reason

Grocery elevator is always automatic anti-leveling reasons; ① due to poor lubrication or lubrication system failure will cause the parts of the transmission parts of the heat burns and axles, resulting in rolling or sliding parts of the parts damaged and forced to repair. ② did not carry out daily inspection and maintenance, failed to check the parts found in the transmission, rolling and sliding parts of the parts of the wear and wear conditions, not according to the degree of wear of the parts for the correct repair, resulting in damage to parts Forced to stop repair. ③ due to the elevator during the operation of the vibration caused by fastening bolts, so that parts displacement, loss of the original accuracy, and can not be repaired in time, resulting in grinding, touch, crashed mechanical parts were forced to stop repair. ④ because the elevator balance coefficient and the standard is too far from the difference caused by overloading the elevator car squatting or red roof, the top speed limiter and safety gear action and forced the elevator to stop running, waiting for repair.
