Zhejiang Aoma Elevator Co., Ltd. is China Home lift Manufacturers.Elevators are generally divided into two categories: lift elevators and escalators. The main components of various types of elevators are different, but they usually include eight major components: traction system, guidance system, car, door system, weight balance system, electric traction system, electrical control system, and safety protection system. Most of the main machines of the elevator are located at the top, including the motor and control system. The motor rotates through gears or (and) pulleys as the power for the chassis and counterweight to move up and down. The control system controls the operation of the motor and other operations, including controlling the starting and braking of the elevator, as well as safety monitoring.
There are many parts in elevator equipment that need to be lubricated, mainly including traction gear box, wire rope, guide rail, hydraulic buffer and car door operator.
For toothed traction elevators, the function of the reduction gear box of the traction system is to reduce the output speed of the traction machine and increase the output torque. There are various structures of the reduction gearbox for the traction system, and the commonly used ones are the worm gear type, the bevel gear type and the planetary gear type. Turbine and worm traction machine turbines are mostly made of wear-resistant bronze, and the worm is made of alloy steel with surface carburizing and quenching. Therefore, no matter what kind of turbine and worm drive, there is a problem of extreme pressure and anti-wear.
Similarly, bevel gear and planetary gear traction machines also have extreme pressure and anti-wear problems. In addition, the oil used for the traction machine should have good fluidity at low temperature, and good oxidation stability and thermal stability at high temperature. Therefore, the oil for the reduction gear box of the toothed traction machine usually chooses the worm gear oil with the viscosity of VG320 and VG460. This kind of lubricating oil can also be used as the lubrication of the escalator chain. The anti-wear and lubricating performance has been greatly improved, and a strong oil film is formed on the metal surface, which adheres to the metal surface for a long time, effectively reducing the friction between the metals, so that the gear can be immediately lubricated and protected when it is started. Gear lubricating oil has excellent water resistance, oxidation resistance and strong adhesion, which can improve the sealing performance of gear box (worm gear box) and reduce oil leakage.
For the oil used in the reduction gear box of the traction machine, generally the temperature of the parts and bearings of the reduction gear box of the elevator should be less than 60℃, and the oil temperature in the chassis should not exceed 85℃. The oil should be selected according to the different models and functions of the elevator. Different grades At the same time, pay attention to the amount of oil, oil temperature and oil leakage.
