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?

Stand on the right side

Q:What are the general items of a construction project

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:This is a question, who can give a full answer

The elevator was broken for the first time to repair, each time to do maintenance must check to confirm the elevator is safe, and finally signed a good maintenance

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.

Q:What are the electrical parts of the elevator and what are their roles?

Control cabinet, used for daily operation to control the inverter, drag the system control, running curve, speed, torque, etc. Weighing, provide car weight information, auxiliary frequency converter communication system for car personnel and room calls and remote control and many more. Door system for door control to open the door
