Heat sealed bearing need refuel

In order to prolong the life of high temperature bearing achieve ideal value, what kind of label filling oil and grease is a good amount of filling and scientific plan, received numerous actual experiments. Generally speaking, the oil loss of life and high temperature bearing life is the same. In addition, the sealing cover design, and the interval of the inner ring, or access to, or non contact, or a maze. Refueling, the sealing cover of disassembly and assembly will inevitably affect its effect, thus influence the service life of high temperature bearing. High temperature bearing seal processing method have? High temperature rolling bearing sealing treatment mainly can be divided into two categories, direct contact seal and non-contact. The so-called system at high temperature bearing seal problem is to high temperature bearing manufacturing enterprise itself as a certain seal function equipment. Such as high temperature bearing with dust cover, sealing ring, etc. This way is seal takes up space and time. The so-called high temperature bearing and seal function devices, is made in teaching equipment end cover internal into sealing technology and equipment, which is good for all kinds of information society. 1, contact seal have felt ring seal, seal ring seal, etc. 2. Non-contact seal axial bending seal, radial bend seal, oil seal, ring seal, etc. For the lifetime of high temperature bearing, the any high temperature roller bearing ring or the initial fatigue damage ( Peeling off or damage) 。 But in both laboratory tests and in practical application, can see clearly that the same high temperature bearing under the condition of the same work, the actual service life is very different. Also has a high temperature bearing 'life', the so-called 'work life' a, suggesting that high temperature bearing life practice before several different definitions of damage can be achieved, not usually caused by the wear and tear of fatigue damage, but it is from wear and corrosion of seal damage. Via high temperature lead to high temperature influence bearing seals, bearing seals, especially as an alternative to high temperature sealing ring for bearing, ball ball high temperature protection bearing seal ring is on the circular one end face of the positive to the two into a circular projection of the inner diameter of the diameter of relatively small bumps with ball high temperature equipment bearing inner ring diameter, the diameter of the mentioned there is a big bump to match the ball high temperature bearing circle of ball diameter; Described within the sealing ring of the aperture is generally not less than high temperature ball bearing inner ring within the aperture. Has the inevitable China oil fire, prevent students often go and simple features such as constructors. Applied widely to improve on high temperature bearing. High temperature bearing seal, it has the following characteristics: the two circular extended upward raised round face, described the inner ring with smaller diameter and the diameter of the combination of high temperature ball bearing, ball described the inner diameter of the ring protruding outer diameter bumps a larger diameter of ball bearing with temperature; Described in the inner ring aperture is not small aperture is greater than the temperature of the ball bearing inner ring. A: high temperature outer spherical bearing can be applied under a different areas: none
