As the power output mechanism of the tower clock, the clock movement plays a key role in the life and accuracy of the tower clock. Most of the movements of the tower clock currently used use worm gear and worm transmission mechanism. In general, the main engine driven by worm gear and worm movement is required to change oil after 3 months to half a year of operation. In the process of oil change, it will be found that there are a large number of worm gear materials in the oil pool to wear precipitated fine powder, so we can not ignore the importance of oil on the movement.
Parts and gear interface need lubricating oil lubrication, in the day and night travel process, gear friction will consume lubricating oil, if not timely add oil, gear friction intensifies, metal debris will hinder normal operation, use time is too long, there will be dust accumulation, long-term past will reduce the service life. Therefore, the movement needs to be cleaned regularly and the parts of the movement are oiled.
The role of oil on the movement: the movement, especially the shaft hole, is generally the part of frequent friction, which is seriously worn out with the movement operation, and needs regular oil treatment to reduce the friction resistance during movement, in order to facilitate the normal travel time, the accuracy of the travel time, and the service life has an important role.
Lubricating oil quality requirements: good chemical stability, can ensure long-term deterioration; Lubricating oil is not volatile, no corrosion; The viscosity should be suitable, the effect of temperature change should be small, and the freezing point should be low; To have good lubrication properties; To be able to do not corrode the steel, copper and other parts of the movement; The oil should contain no impurities.
Main types of lubricating oil: Domestic commonly used 720 meter oil produced in Shanghai, foreign MOEBIUS meter oil (such as: 8300, 8000, 9030, 8200, 941) and so on.
