    Causes and solutions for bearing heating

    High-speed bearings have higher precision and smaller surface roughness than low-speed bearings. With the high-speed development of science and technology, high-speed bearings have become more and more widely used, but the high speed of high-speed bearings often leads to: the lubricant is scattered, it is difficult to adhere, the centrifugal force causes the contact stress to increase sharply, the friction increases, the heat generation surges, etc. And other issues

    1. Reason: low bearing accuracy. Solution: Use the Yongming motor bearing with the specified accuracy class.

    2. Reason: The spindle is bent or the box hole is not concentric. Solution: Repair the spindle or box.

    3. Reason: The belt is too tight. Solution: Adjust the belt to make it tight.

    4. Reason: poor lubrication. Solution: Choose lubricating materials of specified grades and clean them appropriately.

    5. Reason: low assembly quality. Solution: Improve assembly quality.

    6. Reason: The inner and outer shell of the bearing runs a circle. Solution: Replace Yongming motor bearings and related wear parts.

    7. Reason: The axial force is too large. Solution: Clean and adjust the sealing ring gap between 0.2mm and 0.3mm, correct the diameter of the impeller balance hole and check the static balance value.

    8. Reason: The bearing is damaged. Solution: Replace the bearing.

    The shaft parts of machine tools, especially the main shaft, are generally assembled with rolling bearings or sliding bearings and rotate at a high speed, sometimes generating high heat. If this phenomenon is not eliminated in time, it will cause the bearing of the Yongming motor to overheat, and cause the temperature of the corresponding parts of the machine tool to rise and cause thermal deformation. In severe cases, the main shaft and the tailstock will not be equal in height, which will not only affect the accuracy and processing accuracy of the machine tool itself. , And it will burn out the bearing.

    Features, uses and installation of deep groove ball bearings

    Deep groove ball bearings are commonly used rolling bearings. It has a simple structure and is easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has the performance of a certain angular contact ball bearing and can bear the combined radial and axial load. When the speed is high and thrust ball bearings are not suitable, it can also be used to bear pure axial load. Compared with other types of bearings of the same size, this type of bearing has a low friction coefficient and high speed. But it is not shock resistant and not suitable for heavy loads. After the deep groove ball bearing is installed on the shaft, the axial displacement of the shaft or the housing can be restricted within the axial clearance of the bearing, so it can be axially positioned in both directions. In addition, this type of bearing also has a certain degree of aligning ability. When it is inclined 2’-10’ relative to the housing hole, it can still work normally, but it will have a certain impact on the bearing life. Deep groove ball bearing cages are mostly stamped steel corrugated cages, and large bearings are mostly car-made metal solid cages. Deep groove ball bearings are widely used in automobiles, tractors, machine tools, motors, water pumps, agricultural machinery, textile machinery, etc. The deep groove ball bearing with dust cover and sealing ring has been filled with appropriate amount of grease during assembly. It should not be heated or cleaned before installation. There is no need to relubricate during use. It is suitable for operating temperature between -30 ℃ and +120 ℃ between.

    The role of bearings

            In terms of bearing, its function should be support, that is, it is used to support the shaft literally, but this is only part of its function. The essence of support is to be able to bear radial loads. It can also be understood as it is used to fix the shaft. It is to fix the shaft so that it can only achieve rotation, while controlling its axial and radial movement. The consequence of the motor without bearings is that it cannot work at all. Because the shaft may move in any direction, and the motor is required to only rotate when it is working. Theoretically speaking, it is impossible to achieve the role of transmission. Not only that, but the bearing will also affect the transmission. In order to reduce this effect, good lubrication is achieved on the bearings of the high-speed shaft. Some bearings are already lubricated, called pre-lubricated bearings. Most bearings have lubricating oil, which is responsible for not only increasing energy consumption due to friction when running at high speeds, but also frightening the bearings easily.

            What effect does lubricant play on bearings?

            Whether it is a rolling bearing or a sliding bearing, when the shaft rotates, the rotating part and the stationary part can not directly contact, otherwise it will be damaged due to friction. To prevent friction between moving and static parts, add lubricant. The effect of lubricant on the bearing is mainly manifested in three aspects: lubrication, cooling and cleaning.

            Bearings can be divided into many types, rolling bearings, radial bearings, ball bearings, thrust bearings and so on. In terms of its function, it should be support, that is, it is used to support the shaft literally, but this is only part of its function. The essence of support is to be able to bear radial loads. It can also be understood as it is used to fix the shaft. It is to fix the shaft so that it can only achieve rotation, while controlling its axial and radial movement.

            What is the role of the clutch release bearing?

            The clutch release bearing is a kind of thrust bearing (commonly known as the clutch pin). Its function is to move the pressure plate or drive plate that bears the spring thrust to the direction of the clutch cover when the clutch pedal is stepped on, that is, when the clutch pedal is stepped on Turn the release lever to overcome the thrust of the pressure plate spring to complete the separation of the clutch.

            The clutch release lever rotates along with the pressure plate, while the operating mechanism linked with the clutch pedal cannot rotate. In order to adapt to the different motion conditions between the two, thrust bearings are used to reduce friction and wear.

            If the release bearing loses its sliding function due to lack of oil, it will not only produce abnormal noise, but also aggravate the Al loss at the stress point of the release lever, and the effective range of the clutch pedal starting pressure plate will become smaller and smaller. When the clutch plate is not completely separated from the pressure plate, abnormal noise will be produced when the gear is shifted. The wear of the separation lever will cause uneven starting of the pressure plate, and the drive and the driven will be mutually involved, resulting in failure to shift.
