2. The shaft diameter of the gear shaft of the reducer is worn. The main wear parts are the shaft head, keyway, etc. 3. The bearing position of the gear shaft of the reducer is worn. 4. The leakage of the joint surface of the reducer is aimed at the wear problem. The traditional solution of the enterprise is to repair after repair welding or brush plating, but both of them have disadvantages: the thermal stress generated by the high temperature of repair welding can not be completely eliminated, which is easy to cause material damage, resulting in bending or fracture of the parts; However, brush plating is limited by the thickness of the coating and is easy to peel off, and the above two methods are to repair the metal with metal, which cannot change the "hard to hard" fit relationship, and will still cause repeated wear under the combined action of various forces. For some large bearing enterprises, it is impossible to solve the problem on site, and they mostly rely on outsourcing repair. In view of the above problems, modern western countries often use the repair methods of polymer composite materials, while the most widely used are the Meijiahua technology products, which have strong adhesion, excellent compressive strength and other comprehensive properties. The application of polymer materials for repair can avoid disassembly and machining, which is not affected by the thermal stress of repair welding, and the repair thickness is not limited. At the same time, the metal materials of the product have no concession, which can absorb the impact and vibration of the equipment, avoid the possibility of wear again, and greatly extend the service life of the equipment components, save a lot of downtime for the enterprise, and create huge economic value. To solve the problem of leakage, the traditional method needs to replace the sealing gasket or apply sealant after disassembling and opening the reducer, which is not only time-consuming and laborious, but also difficult to ensure the sealing effect, and leakage will occur again in operation. The polymer material can be used to control the leakage on site. The material has excellent adhesion, oil resistance and 350% tensile strength, which can overcome the impact caused by the vibration of the reducer and solve the leakage problem of the reducer for the enterprise
The lubrication of cycloidal pinwheel reducer requires (I) grease lubrication. 1. The single-stage l #~4 # double-stage 42 # reducer is lubricated with grease. (Molybdenum disulfide-2 or ZL-2 lithium-based grease and other grease are recommended) 2. Grease supplement: when decelerating, unscrew the breather cap of the needle gear housing, and press the grease into the breather cap hole with a grease gun. 3. The amount of grease injected shall be 1/3-1/2 of the internal volume of the reducer. It is not advisable to add too much grease to avoid stirring heat.
