What's going on with the overall eccentric bearing? What are the correct installation steps for eccentric bearings?
Correct installation steps of eccentric bearings:
Overall eccentric bearing installation The quality of the overall eccentric bearing installation will affect the accuracy, life and performance of the overall eccentric bearing. Therefore, please fully study the installation of the integral eccentric bearing, that is, please install the integral eccentric bearing in accordance with the operating standards including the following items.
1. Clean the integral eccentric bearing and related parts. (For integral eccentric bearings that have been lubricated with grease and have oil seals or dust covers on both sides, the sealing ring of the integral eccentric bearing does not need to be cleaned before installation.)
2. Check the size and finishing of relevant parts
3. Installation method The installation of the overall eccentric bearing should be based on the overall eccentric bearing structure, size and matching properties of the overall eccentric bearing components. The pressure should be directly applied to the end face of the tightly fitting ferrule, and the pressure must not be transmitted through the rolling elements. The installation of the overall eccentric bearing generally adopts the following method:
1) Press fit the inner ring of the integral eccentric bearing to make a tight fit with the shaft, and when the outer ring and the integral eccentric bearing seat hole are loosely matched, you can use a press to press the integral eccentric bearing onto the shaft first, and then install the shaft together with the integral eccentric bearing into the integral eccentric bearing seat hole. When pressing, place an assembly sleeve (copper or soft steel) made of soft metal material on the end face of the inner ring of the integral eccentric bearing. The inner diameter of the assembly sleeve should be slightly larger than the journal diameter, and the outer diameter should be slightly smaller than the inner ring rib of the overall eccentric bearing to avoid pressing on the cage.The outer ring of the integral eccentric bearing has a tight fit with the integral eccentric bearing seat hole. When the inner ring and the shaft have a loose fit, the integral eccentric bearing can be pressed into the integral eccentric bearing seat hole first. At this time, the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole. If the integral eccentric bearing ring is a tight fit with the shaft and seat hole, the inner and outer rings must be pressed into the shaft and seat hole at the same time. The structure of the assembly casing should be able to simultaneously press the end faces of the inner and outer rings of the integral eccentric bearing.
