Mentioned worm reducer, it is logical that people should think of reducer. The internal structure of the reducer and reducer is different, they belong to different devices. For the worm reducer, it is not just a model, it itself is divided into some more types. Often heard of the WP worm gear reducer, there is a worm worm reducer. For both types of machines, the Archimedes worm reducer should be reminded of. Maybe here there are many new terms, understanding of everyone had a certain degree of difficulty. However, this is a necessary way to learn. First, the worm gear reducer FAQ Worm wear. The worm gear generally adopts tin bronze, and the matched worm material is hardened with 45 steel to HRC4555, or 40Cr hardened HRC5055, and then ground to a roughness of Ra0.8μm by an worm grinder. Reducer wear very slow during normal operation, some reducer can be used for more than 10 years. If wear faster, it is necessary to consider the selection is correct, whether the overload operation, as well as the worm gear material, assembly quality or use of the environment and other reasons. 2. Driven small bevel gear wear. Generally occurs in the vertical reducer installed, mainly with the addition of oil and oil varieties. Vertical installation, it is easy to cause the lack of lubricant, the reducer stops running, the transmission gear oil between the motor and reducer lost, the gear can not get the lubrication protection. Gear reducer starts, the gear can not be effectively lubricated due to mechanical wear and tear or even damage. 3. Worm bearing damage. In the event of a malfunction, even if the gearbox is well sealed, it is often found that the gear oil in the gearbox is emulsified, rusting, corrosion, and damage to the bearings. This is because the reducer after running for some time, the gear oil temperature and cooling water condensate generated after mixing with water. Of course, but also with the bearing quality and assembly process are closely related. Second, the worm gear reducer solution 1. Ensure assembly quality. To buy or homemade some special tools, remove and install reducer parts, try to avoid using hammer and other tools percussion; replacement gears, worm gear, try to use the original parts and pairs of replacement; assembly of the output shaft, we should pay attention to Tolerance with; to use anti-sticking agent or Hongdan oil to protect the hollow shaft to prevent wear and tear with rust or area scale, maintenance difficult to disassemble. 2. Selection of lubricants and additives. Worm gear reducer is generally used 220 # gear oil, heavy load, frequent start-ups, the use of poor environment reducer, the choice of some lubricant additives, gear reducer in the stop running gear oil is still attached to the gear surface, the formation of protection Membrane, to prevent heavy load, low speed, high torque and direct contact between metals at startup.
