TIMKEN bearings is properly installed, which will affect accuracy, longevity, performance. Therefore the design and Assembly departments for bearing installation the full study. Want to be installed in accordance with operational standards.
Job standards projects often are as follows:
(1) clean bearing and bearing related parts;
(2) check the size and finishing of correlative parts;
(3) installation;
(4) once the bearing is installed check;
(5) supply of lubricants.
1) bearing preparation
Due to the bearing anti-rust treated and packed, so no new year do not open the package before installing.
In addition, TIMKEN bearings coating antirust oil with excellent lubricating properties, for general purpose of filling grease TIMKEN bearings or bearings, can be used directly without cleaning. But for instrument bearings or bearings for high-speed rotation, clean cleaning oil antirust oil wash away when bearings are easy to rust, cannot be placed for a long time.
2) testing of shaft and housing
Clean the bearing with the shell, confirmed Burr without leaving scars or mechanical processing. Shell must not be abrasive (such as SiC, Al2O3) sand, chips, etc.
Hopes in the forthcoming before installation, just open the bearing package. General grease lubrication, no cleaning, filling grease directly. Lubricating oil, ordinary or cleaning, however, instruments or TIMKEN bearing used in high speed, to use clean oil wash, dropping the antirust coating on the bearing. Bearings removed rust, rust, so cannot be placed aside. Furthermore, into the bearings with grease, no cleaning used directly.
TIMKEN bearing installation methods, due to bearing structures, fit, vary depending on the conditions, in General, due to rotate, so the interference fit is required for the inner rings. Bearings with a cylindrical bore and more with presses onto, or multiple-use and charging methods. Tapered bore, mounted directly on tapered shaft or sleeve installation.
When you install into the shell, General clearance, there is interference in the outer ring, normally, the pressure into pressure, or have installed after the cooling methods of shrink fit. Using dry ice as a cooling agent, shrink fit occasion, moisture in the air will condense in the TIMKEN bearing surface. So, you need appropriate antirust measures.
Bearing in the installation process, or if the installation method, is caused when mounting and dismounting of bearings, bearing Raceway surface and rolling surfaces cause a linear bearing scars.
Leading causes of injuries occur because the bearings at the time of installing, removing, the bearing inner ring, outer ring tilt; or are in the process of installing and removing the impact load. Resulting in bearing scars appear.
So in order to avoid injuries in the TIMKEN bearing, in addition to appropriate tools are used during installation or removal, we still have to use impact loading of the punch and prevent the TIMKEN bearing, and centering of the note also that at the time of installation.
