No matter what type of construction machinery equipment, it is necessary to cooperate with the spindle to transfer the engine power to the processing part. This process also needs to use various types of bearings, as the spindle special bearings in addition to choosing the right model, but also the correct installation, then the spindle special bearings correct installation method is what? This guide describes this in detail.
What is the special spindle bearing installation method?
1, Heating Installation
The special bearing of the spindle is heated to a certain temperature in the heater or oil bath, which can make the bearing slightly expand. After the temperature is suitable, the bearing is quickly installed on the spindle of the equipment, and attention is paid to controlling the heating temperature and time to avoid the deformation of the bearing.
2, Pressing Installation Method
Small and medium-sized bearings or loosely fit bearings are more suitable for using the pressing installation method, and the bearing is evenly pressed into the equipment spindle with a tool or press to ensure a tight and uniform fit between the bearing and the shaft. When pressing, soft metal material can be padded on the end face of the bearing inner ring to make assembly sleeve, which can protect the bearing and shaft from being damaged.
No matter what kind of spindle special bearing installation method is used, after installing the bearing, it is necessary to fix the bearing to the main shaft with nuts or bolts, and pay attention to uniform force application, do not let the bearing tilt or deformation.
Special Spindle Bearing Installation Preparation
1, the model check, to determine the bearing and shaft with the appropriate size, too large and too small will affect the stability of the bearing work.
2, clean the surface, thoroughly clean the bearing surface, remove oil, rust and other impurities, can improve the bearing installation quality and operating stability.
3, according to the bearing type size, choose the appropriate installation tools, such as copper rods, hydraulic devices, heaters, etc., need to ensure that the quality and accuracy of the installation tools meet the requirements.
Spindle Bearing installation precautions
1, when installing the main shaft bearing, to ensure that the bearing is not impacted or scratched, try to use tools to operate.
2, the use of heating installation method, strictly control the bearing heating temperature, time, to avoid bearing overheating or deformation. The heated bearing should be quickly installed on the spindle, and do not wait until cooling affects the installation effect.
3, the accuracy between the bearing and the shaft should meet the requirements. If the match is too tight or too loose, it will affect the bearing operation effect and service life.
4, after the installation is completed, it is necessary to do the lubrication treatment, and then check whether the bearing can work normally, if there is a problem, timely treatment and maintenance.
Conclusion
The correct installation of the main shaft bearing is vital, this guide describes the installation method and preparation work in the form of text to help the mechanical operator, VKUKEN also produced a detailed installation steps and schematic diagram, if you encounter difficulties in the installation of the main shaft bearing, please send us a message, our engineers will send the installation instructions to you.
