Jintai bearing conditions and environmental conditions
Correctly
grasp the use of Jintai bearings in the use of mechanical parts and
conditions of use and environmental conditions is appropriate to choose
the premise of Jintai bearings. To do so, you need to obtain the following aspects of data and information:
1, the function and structure of the mechanical device
2, Jintai bearing the use of parts
3, Jintai bearing load (size, direction)
4, the rotation speed
5, vibration, shock
6, Jintai bearing temperature (ambient temperature, temperature rise)
7, the surrounding atmosphere (corrosive, clean, lubricity)
The
proper use of the Jintai bearing is to reduce the Jintai bearing
failure and to extend the reliability of the Jintai bearing life,
including the correct installation and reasonable lubrication. The following describes the use of Jintai bearings requirements.
1, Jintai bearing disassembly
Jintai bearings should be cleaned before installation. When
installing, use special tools to press the bearing straight and evenly,
do not use the hand hammer percussion, in particular, prohibit direct
hit on the Jintai bearings. When
the Jintai bearing seat and seat with the loose, it should repair the
seat hole or replace the Jintai bearings, do not use the Jintai bearing
with the surface of the pitting or pad copper method of barely use. Jintai bearings should be removed using the appropriate pull the
Jintai bearings out, do not use chisels, hand hammer and other
percussion Jintai bearings.
2, Jintai bearing lubrication
Jintai bearings commonly used lubricants are lubricants and grease two. When
the axis of the peripheral speed is less than 4-5m / s, or the car can
not use lubricating oil lubrication parts, are used grease lubrication. Grease lubrication has the advantage of simple sealing structure,
grease is not easy to lose, little affected by the temperature, plus a
grease can be used for a long time.
Lubricant
lubrication has the advantage of small friction resistance, and can
heat, mainly for high-speed and high temperature working environment
Jintai bearings. Lubricant
grades should be selected according to the requirements of the car
manual, and then replace the car maintenance cycle in a timely manner,
after the release of old oil to the organization after the cleaning and
then add new oil, refueling should be added to the provisions of the
marking, or with the fuel flush (Depending on the specific structure of the car, the request may be), not more.
Use
grease to pay attention to two issues, one is to follow the
requirements of the car manual, use the appropriate grades of grease. For example, the car pump Jintai bearings should not use Naji grease, because of its poor water resistance. Second,
to join the Jintai bearing grease to moderate, generally only fill
Jintai bearing cavity 1/2-l / 3 is appropriate, too much not only
useless, but also increase the Jintai bearing operating resistance, so
that heating up. Special
note is the car hub Jintai bearings, to promote the "empty hub
lubrication", that is only in the Jintai bearing coated with a layer of
grease can be, otherwise, not only waste and poor heat, but also make
the grease heat spill, May affect the braking performance.
