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

This mainly depends on the gears used in what machinery and the hardness of the gear itself. If the accuracy of the gear itself is 7 or more and grinding is the finishing method, it is necessary to consider the small letter tolerance group, usually base section or tooth profile and other problems, first measure base section, such as base section need to pass through the improvement Tooth surface roughness to noise reduction; if the hobbing for the finishing method, the best plus grinding can be resolved. In addition, the parallelism of the two bearing holes can also cause tooth contact to produce noise.

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!

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.
