The bearing is installed correctly, affect the accuracy, life, and performance. Therefore, the design and assembly departments should fully study for the installation of the bearing. To be installed in accordance with the operating standards. Operating standards of the project is usually as follows:
(1), cleaning the bearing and associated parts
(2), check the size of the associated components and finishing
(3), the installation
(4), installed after the inspection of the bearings
(5), supplying lubricant
I hope to be installed, just open the bearing packaging. General grease lubrication, cleaning, directly populate grease. The lubricating oil, Common without cleaning, However, the equipment used or the high speed with a bearing, etc., use clean oil wash, the anti-rust agent coated on the bearing is removed. Removing the rust inhibitor bearing rust easily, so can not be placed on regardless. Furthermore, a grease-sealed bearings, cleaning is not used directly.
The method of installation of the bearing, because the bearing structure, with different conditions, in general, due to the rotation of the multi-axis, so the inner ring needs interference fit. Cylindrical bore bearings pressed into the multi-purpose presses, or hot charging method. The occasion of the tapered bore, directly mounted on the taper shaft, or with the sleeve is mounted.
When mounted to the housing, generally clearance with multi outer amount of interference, usually pressed into the press, or are also shrink fit method installed after the cooling. With dry ice as the cooling agent, shrink fit installation of the occasion, the moisture in the air will condense on the surface of the bearing. So, you need the proper rust prevention measures.
: Removing the lower bearing maintenance for cleaning of the bearing, the first record of the appearance of the bearing, to confirm the residual amount of the lubricant, the sampling after the check of the lubricant used, wash the bearing. As a cleaning agent, ordinary gasoline, kerosene.
The removed bearing cleaning, cleaning and fine cleaning sub-coarse, were placed in the container, first put the metal bottom of the network, bearing no direct contact with the container dirt. The rough cleaning the bearing with dirt rotation, will damage the bearing rolling surface, it should be noted. Rough cleaning oil, use a brush to remove to grease, adhesive material, generally clean, transferred to sperm washing.
Sperm washing, cleaning oil bearing while rotating, while carefully cleaning. In addition, cleaning the oil should be kept clean.
Bearing overhaul and judgment: In order to determine whether the removed bearing can be used to check bearing wash. Check raceway, rolling surface, with the surface state, cage wear, increased bearing clearance and damage decreased unrelated dimensional accuracy exception. Non-separable type of small ball bearings, the inner ring with one hand and the level of support the rotating outer ring to confirm whether smooth.
Tapered roller bearings and other separation-shaped bearing, rolling element, the outer ring raceway were examined.
Rotating the large bearing failure hand, pay attention to check the rolling body raceway to maintain the appearance of the rack, wall surface, the importance of bearing the higher the greater the need for careful checking.
