What are the common faults of the
reducer? Unlike household appliances and some standard products, the
reducer basically has no problems. On the contrary, it often has many problems, and some even break down after a few times of use. There are many reasons. Let me talk about some points; Due to the poor operating environment of the reducer, wear, leakage and other faults often occur. The main types are: 1. The bearing chamber of the reducer is worn, which also includes the wear of the shell bearing box, the bearing chamber of the inner hole of the box and the bearing chamber of the gearbox; 2. The shaft diameter of gear shaft of reducer is worn, and the main wear parts are shaft head, keyway, etc; 3. The bearing position of the transmission shaft of the reducer is worn; 4. Leakage of reducer joint surface; 5. The ventilation cap was not replaced. As a manufacturer, I especially hate this point; For the wear problem, the traditional solution is repair welding or machining repair after brush plating, but both of them have some disadvantages: the thermal stress caused by repair welding high temperature can not be completely eliminated, which is easy to cause material damage and lead to bending or fracture of parts; However, brush plating is easy to peel off due to the limitation of coating thickness, and the above two methods use metal to repair metal, which can not change the “hard to hard” coordination relationship, and will still cause re wear under the comprehensive action of various forces. For some large bearing enterprises, they can’t solve it on site, and they have to rely on outsourcing repair. In view of the above problems, contemporary western countries mostly use the repair methods of polymer composites, which have comprehensive properties such as super adhesion and excellent compressive strength. The application of polymer materials for repair can avoid disassembly and machining, without the influence of repair welding thermal stress, and the repair thickness is not limited. At the same time, the metal materials of the product do not have concessions, which can absorb the impact and vibration of the equipment, avoid the possibility of re wear, greatly prolong the service life of equipment components, and save a lot of downtime for the enterprise, Create huge economic value. For the leakage problem, the traditional method needs to replace the sealing gasket or apply sealant after dismantling and opening the reducer, which is not only time-consuming and laborious, but also difficult to ensure the sealing effect, and there will be leakage again in operation. The polymer material can control the leakage on site. The material has superior adhesion, oil resistance and 350% elongation, overcomes the influence caused by the vibration of the reducer, and solves the problem of reducer leakage for the enterprise. Because there are many types, specifications and parameters of the reducer, many people in the industry do not know how to select the correct type, so it is normal for the user to have problems in the type selection, resulting in damage to the reducer or short service life; There is also a very important problem. In order to reduce the cost, some equipment manufacturers and user manufacturers choose one or two smaller specifications of the reducer model. When the reducer model is small, the price will come down, which is also a main reason why the reducer often has problems. The above views are for your reading only. Don’t criticize whether they are right or not. Thank you for
