Motor end cap bearing chamber wear quick repair new technology
The motor is a device that converts electrical energy into mechanical energy. No matter how different the size and type of the motor is, there are two parts - the motor rotor and the end cap bearing chamber. The motor end cover is the main component that supports the rotor. It is generally cast iron. It is widely used in motors because of the easy processing of casting parts and high cost performance.
Motor FAQ:
Motor end cap bearing chamber wear and motor shaft bearing position wear often occur during motor operation.
Reasons for the wear of the motor cover bearing chamber:
1. Processing error, resulting in matching clearance;
2. Non-standard disassembly and installation, resulting in damage and wear of the bearing chamber;
3. Insufficient contact surface, resulting in metal fatigue;
4. Bearing damage, resulting in bearing chamber wear
Repair technology for solving the wear of the motor end cover bearing chamber:
The existing measures to solve the wear of the bearing housing of the motor end cover are mainly based on replacement, but some enterprises with small wear amount use the copper pad and the grinding point to quickly repair the restored production. In addition, some machining units also use the inserting measures. This method is only used when there are no spare parts for some motor end covers.
Emergency padding and pitting repair can only solve a short period of time. The motor quickly wears under load and operation and aggravates the amount of wear, causing vibration of the motor and affecting safe operation. How to fix it quickly
The wear of the motor end cover bearing must first understand the cause of the wear of the motor bearing chamber and effective control:
The reason for metal wear is: normal fatigue wear of metal, which is the inherent characteristics of metal itself; second, the problem of mating relationship, no matter how high the precision of machining in the process, it can never reach 100% of the mating surface of the component. From the microscopic observation, the mating surface of the metal can only be 30%-50%, so the small force surface of the joint is also one of the root causes of metal fatigue wear.
Sore carbon nano polymer repair motor bearing room new technology:
The characteristics of carbon nano-polymer repair technology, first, the technology is essentially different from the traditional repair process, can not rely on metal thinking to treat, is a new application technology; Second, the motor is running, mainly by various pressures and The impact of impact, carbon nano-polymer material repair wear is focused on the comprehensive mechanical properties, that is, the elastic deformation and toughness and rigidity of the metal. The material can withstand a pressure of 1200 kg per square centimeter, which can fully meet the various shaft operating pressures. And strength requirements.
In addition, since the carbon nano-polymer is in the form of a paste, it can completely achieve 100% surface matching after repair, thereby avoiding the occurrence of gaps. Third, after the solidification of Sole carbon nano-polymer material, it can realize machining of milling, milling, planing, grinding, etc., and the bearing room wear size can be restored by different repair measures.
