        Worm gear reducer is composed of worm gear, worm, cast steel casing, plane pressure bearing, taper bearing and oil seal. The worm gear of its worm gear reducer is also called curved cylindrical worm, in which the tooth surface is generally arc-shaped concave surface.The code name is the arc tooth worm in the ZC worm industry. Its origin is the concave worm of G.Niem-ahh in the former West Germany and the arc tooth cylindrical worm in my country (JB2318-79). Belongs to this kind of worm, he and the worm wheel form a worm gear and worm pair.Vibration, noise, excessive temperature rise and jamming problems during the lifting and driving process of the worm gear reducer:
        1. The cause of the noise during the use of the reducer and how to deal with it?
        Answer: The reason for the noise during the operation of the worm gear reducer is that the split ends of the multi-head worm of the fast worm gear reducer are uneven, and the reason for the slow noise is the quality of the bearing.
        2. What are the reasons for the excessive temperature rise and the jamming of the reducer and how to deal with it?
        Answer: The maximum temperature of the reducer under normal working conditions should not exceed 45 degrees Celsius. If there is a high temperature, the machine should be immediately stopped for inspection. Generally, the reason for this problem is that the reducer with this tonnage is too small and overloaded, or the worm and worm gear end cover In line with the high temperature situation caused by over-tightening, the input speed does not rule out the grease lubrication of the external worm gear reducer. The maximum speed of the worm shaft must not exceed 1000 min/s. If the input speed is too high, it will also be high and stuck. The treatment method is to reduce the input speed, check whether the embedding fit of the gland is too tight and whether the worm gear reducer is out of oil.
        3. The cause of the jitter of the reducer during normal use and how to deal with it?
        Answer: The reasons for the jitter of the worm gear reducer after additional load during use are uneven screw pitch, uneven worm split, flat pressure bearing and taper bearing quality not up to standard, and the upper and lower sheaths of the screw are too tightly matched, and The problem of dissatisfaction with the installation.
