Cycloidal pinwheel reducer has abnormal sound, whether the fault is eliminated: that is to listen carefully to the sound from the reducer, whether it is regular, this is very important; if it is regular, then this is normal, if the sound is out of scale then It must be a malfunction.The working sound of the reducer is irregular: then it must be a fault. Generally, in this case, the problem may appear in the motor part and the reducer part. Of course, most of the problems are caused by the reducer.We need to check whether the curved plate is worn and whether the eccentric body bearing is damaged. If there is no problem with the above two, then check whether the bearings of the input and output parts are damaged.The lubricating oil often used by the cycloid reducer: at normal temperature and low speed operation: generally 40#-50# industrial lubricating oil, which is sufficient; if the speed is high and the working state is under high pressure, it is recommended to use 70#- 90# gear oil; if the reducer is often in high and low temperature environment Read More

Teach you to install the reducer correctly: The reducer is a topic that cannot be finished, because the continuous technology is innovating and the technology is being eliminated, so we can only ask everyone to make continuous progress and absorb new knowledge.Knowledge is innovating, and people are also changing. The change of the reducer may not be so easy for everyone to see, but if you have seen the reducer in the 1970s, you will feel that the world is developing very fast today.In fact, not only the reducer, but everything else is developing.When all walks of life are using harmonic, belt drive reducer, planetary gear reducer and other members of the big family, maybe no one will think how long it will take to change from the original original function to the current new function.

Compared with ordinary cylindrical gear reducer and worm gear reducer, the involute servo reducer with small tooth difference has the advantages of small size, light weight, large transmission ratio, high efficiency, large carrying capacity, reliable operation and long life; Compared with the linear pin wheel planetary reducer, in addition to the above advantages, in terms of processing, it can be processed on a general gear processing machine tool with a general tool.Therefore, it has the advantages of lower cost.And what about the carrying capacity? This paper analyzes and discusses the carrying capacity of the gear of the two-tooth difference servo reducer by using the finite element method.The planetary reducer with small tooth difference is an internal meshing transmission.It is generally believed that its pair of meshing tooth surfaces are convex tooth surface and concave tooth surface respectively, the curvature center of the two is on the same side of the tooth surface, the concave direction of the tooth surface is the same, the curvature radius difference is small, and the contact deformation results in a large contact area. .Therefore, the contact stress of the gear teeth is greatly reduced, and the contact strength is correspondingly improved.At the same time, it can also be reduced by reducing the height of the addendum Read More

Everyone in the reducer industry knows that the noise of the reducer, especially the worm gear reducer, is a headache for many reducer manufacturers.Reducing noise and ensuring stability during operation are the primary conditions for the quality of the reducer.Next, let's briefly understand how to reduce the noise of the reducer during the processing of the reducer.For how to reduce the noise of the reducer, many scholars at home and abroad regard the change of the meshing stiffness of the gear teeth as the main factor of the dynamic load, vibration and noise of the gear.To reduce noise, dynamic loads and speed fluctuations are minimized through refinements.Practice has proved that this method is an effective method.However, in this way, molding equipment is required during processing, which is usually impossible for most small and medium-sized factories.After years of research, a gear design method is proposed, by optimizing the gear parameters, such as deformation coefficient, tooth height coefficient, pressure angle and center distance, reduce or avoid Read More

After the output shaft of the reducer is broken, it needs to be welded.The broken part of the shaft is smoothed out before welding.Together, in order to reduce the welding stress, a certain method is adopted in the planning of the welding groove.The following describes the correction method for the cracking of the output shaft of the reducer: First, plan the U-shaped groove according to the cracking condition and the diameter of the part.The groove has a width of 20mm and a depth of 37mm.In order to make the shape of the groove common, the end face of the split portion is flattened, and a forming tool is used for groove processing.To prevent stress build-up, all parts of the groove should be rounded to reduce the proportion of base metal that melts into the weld metal to prevent weld cracking.The welding gap also has an important influence on the welding quality.If the gap is too small, defects such as incomplete penetration or excessive welds may occur, and if the gap is too large, it is easy to burn through.The shaft gap is selected as 2mm.(1) Correct the planning of the cycloid reducer; Read More

1. Reducer heat and oil leakage In order to improve efficiency, worm gear reducer manufacturers usually use non-ferrous metals as worm gears, while hard steel is used for worm gears.Due to the sliding friction drive, more heat will be generated during operation, which will cause the difference in thermal expansion between the various parts of the reducer and the seal, thus forming a gap on each mating surface.As the temperature rises, the lubricating oil will become thinner and easily cause leakage.There are four main reasons for this situation.First, the material matching is unreasonable; second, the surface quality of the meshing friction surface is poor; third, the choice of lubricating oil is not correct; fourth, the assembly quality and the use environment are poor.2. The worm wheel is worn out. The worm wheel is usually made of tin bronze, and the matching worm material is hardened to HRC4555 with 45 steel, or hardened to HRC5055 with 40Cr, and then ground to a roughness of Ra0.8m with a worm grinder.The reducer wears slowly during normal operation, with some deceleration Read More
