People often ask how to maintain the planetary gearbox. In fact, the maintenance of the gearbox is relatively simple. The correct installation in the early installation and the subsequent use can be well lubricated and maintained. It can be maintained normally without overloading during operation. operation. Today, I will introduce to you how to maintain the gearbox.
1. The bearing chamber of the planetary gearbox is worn, including the failure of the casing structure, the bearing box, the bearing chamber of the inner hole of the box, and the bearing chamber of the gearbox.
2. The shaft diameter of the planetary gearbox gear is worn, and the main wear parts are the shaft head, keyway, etc.
3. The bearing position of the planetary gearbox drive shaft is worn.
4. The joint surface of the planetary gearbox leaks.
For the main wear problem, the traditional solution of the enterprise is to repair welding after brush plating or machining repair, but there are some drawbacks in these two methods. In order to solve the leakage problem, we usually use traditional methods to disassemble the gearbox, replace the gasket or use the sealant, which is not only time-consuming and labor-intensive, but also difficult to effectively ensure the sealing effect, and information leakage will develop again during operation.
1. The operator of the planetary gear gearbox should be familiar with the internal control structure and function of the gearbox, as well as their operation and maintenance procedures. Before analyzing the operation, please read the operation manual, and operate and maintain according to the requirements of the operation manual.
2. Pay attention to the working time of the planetary gearbox to avoid too long working time, which will cause the machine to heat up and affect the use;
3. Use lubricating oil reasonably, and select the appropriate lubricating oil according to the different power and model of the enterprise. At the same time, we need to check the oil quantity and the tightness of the machine.
4. The inside of the machine needs to be cleaned and adjusted regularly to avoid loose or worn parts.
5. Bearing lubrication For the lubrication of rolling bearings in the gearbox, the commonly used lubricants are lubricating oil and grease. When selecting lubricating oil, factors such as bearing load, speed, temperature, working environment, etc. should be considered. The higher the bearing load, the higher the temperature, and the higher the viscosity of the lubricating oil. When the bearing load is small, the temperature is low, and the rotational speed is high, low-viscosity lubricating oil can be used. Too much or too little oil in the bearing can cause the bearing to overheat. When the bearing speed n=1500r/min, the oil level should be lower. When the peripheral speed of the bearing rotating race is not more than 4-5m/h, it can be lubricated with grease. When lubricating with grease, the amount of grease in the bearing can occupy 1/3-1/2 of the bearing cavity space. For the lubrication of rolling bearings in the gearbox, the lubricating oil in the gearbox oil pool can be directly used, and then the lubricating oil in the gearbox oil pool must be introduced into the bearing.
The operation and maintenance personnel of the planetary gearbox need to analyze and check regularly. The continuous improvement of the early work will determine the occurrence of the later situation, so as to make better use of the gearbox and create more economic benefits.
The above is an introduction to some common problems in the operation of planetary gearbox and related maintenance. Those who need planetary gearbox are welcome to consult Shenzhen Weidong Automation Equipment Co., Ltd.
