Precautions for maintenance and installation of eccentric IKO bearing

 Maintenance of eccentric IKO bearing:

  1. In order to maintain the original performance of IKO bearing in good condition for as long as possible, maintenance and repair are required to prevent accidents, ensure the reliability of operation, and improve the productivity and economy.
  2. Maintain the operation standard of the corresponding mechanical operation conditions and carry out it regularly. The contents include monitoring the operation status, replenishing or replacing the lubricant, and regular disassembly inspection.
  3. As maintenance items during operation, there are rotation sound, vibration, temperature, lubricant state of eccentric IKO bearing, etc.

Maintenance of eccentric IKO bearing: cleaning of IKO bearing:

  1. When disassembling the eccentric IKO bearing for maintenance, first record the appearance of the eccentric IKO bearing, confirm the residual amount of lubricant, and then clean the eccentric IKO bearing after sampling the lubricant for inspection. Gasoline and kerosene are commonly used as cleaning agents.
  2. The removed eccentric IKO bearing shall be cleaned by coarse cleaning and fine cleaning. They shall be placed in the container, and the metal mesh shall be placed on the bottom first to prevent the IKO bearing from directly contacting the dirt of the container. During rough cleaning, if IKO bearing rotates with dirt, the rolling surface of IKO bearing will be damaged, and attention should be paid. In the coarse cleaning oil, use a brush to remove the grease and adhesion, and then transfer to the fine cleaning.
  3. Fine cleaning is to carefully clean the eccentric IKO bearing while rotating in the cleaning oil. In addition, the cleaning oil should always be kept clean.

Maintenance and judgment of eccentric IKO bearing

  1. In order to judge whether the disassembled IKO bearing can be used, it should be inspected after the IKO bearing is cleaned. Check the state of the raceway surface, rolling surface and mating surface, the wear of the cage, the increase of the clearance of IKO bearing and the damage caused by the irrelevant reduction of dimensional accuracy. For non separable small ball IKO bearing, use one hand to support the inner ring horizontally and rotate the outer ring to confirm whether it is smooth.

Selection of eccentric IKO bearing:

  1. the market requirements and performance of various mechanical devices and instruments using rolling IKO bearing are increasingly strict, and the conditions and performance required for IKO bearing are also increasingly diversified. In order to select a suitable IKO bearing from a large number of structures and sizes, it needs to be studied from various angles. 
  2. When selecting IKO bearing, generally, the structure of IKO bearing is generally determined by considering the arrangement, installation and disassembly difficulty of IKO bearing as the shaft system, the space and size allowed by IKO bearing and the marketability of IKO bearing. Secondly, the design life of various machines using IKO bearings and various durability limits of IKO bearings are compared and studied, and the size of IKO bearings is determined. When selecting IKO bearings, it is often inclined to consider only the fatigue life of IKO bearings. 
  3. The grease life, wear and noise caused by grease aging also need to be fully studied. Furthermore, according to different applications, it is necessary to select IKO bearings with special design for accuracy, clearance, cage structure, grease, etc. However, there is no certain sequence and rules for selecting IKO bearings. The priority should be given to the conditions, performance and related matters required by IKO bearings, which is particularly practical.
  1. It is hoped that the IKO bearing package can be opened just before installation. General grease lubrication, no cleaning, directly filled with grease. It is not necessary to clean the lubricating oil for lubrication. However, the IKO bearing for instrument or high-speed use should be cleaned with clean oil to remove the rust inhibitor coated on the IKO bearing. IKO bearing with rust inhibitor removed is easy to rust, so it can not be put aside. In addition, IKO bearings sealed with grease can be used directly without cleaning.
  2. The installation method of IKO bearing varies according to the structure, fit and condition of IKO bearing. Generally, the inner ring needs interference fit due to the shaft rotation. The cylindrical hole IKO bearing is usually pressed by a press or hot assembled. In the case of taper hole, it can be directly installed on the taper shaft or installed with a sleeve.
  3. When it is installed in the shell, there are usually many clearance fits and the outer ring has interference. It is usually pressed by a press, or there is a cold shrink fit method for installation after cooling. When dry ice is used as the coolant, the moisture in the air will condense on the surface of IKO bearing in the case of cold shrink fitting installation. Therefore, appropriate rust prevention measures are required.

Installation of eccentric IKO bearing: whether the eccentric IKO bearing is installed correctly affects the accuracy, service life and performance. Therefore, the design and assembly department should fully study the installation of IKO bearing. It is hoped that the installation will be carried out according to the operation standard. The items of operation standard are generally as follows:

  1. Clean IKO bearing and IKO bearing related parts
  2. Check the dimension and finishing of related parts
  3.  Installation
  4. Inspection after IKO bearing is installed
  5. Supply lubricant
