Must be based on gear engagement, must be in accordance with the two gear contact pattern, backlash and tooth tip clearance requirements, namely to the reducer rotating light, flexible, shall prevail.
Bearing working temperature range is quite broad, and it can in - which requires
C is easy to start, but also work at high temperature, also need to adapt to the temperature change after parking.
If the bearing more than ℃ temperature even move to reduce the bearing life for a long time, the choosing principle of lubricating oil, lubricating oil is widely used in sliding bearing lubricant, the traditional airlines launched main bearing materials is M more, oil ring is a seamless, bearing width to diameter ratio is less than, can only use a ring, or need to use two oil ring.
Although has a small cross-section, bearing still has high load capacity, needle roller bearing with thin and long (
Mm or less roller diameter D, L/D or greater.
Vertical mill rocker bearing chamber wear online repair case: a raw material for cement group problems larger low-frequency vibration grinding, and the vertical mill using about -
Years, a roller rocker support part has been severely damaged, serious wear of ~ mm, the early stage of the enterprises have adopted other metal repair process to repair, bearing the outage overhaul, it found that the original repair materials have disappeared due to wear and tear.
Reason: friction heat -

Measures: bearing seal & amp;

Good lubrication Raymond mill principle of work, determine the milling process depends on a lot of friction and pressure, friction heat generating believe that everyone can understand the truth, so Raymond mill host temperature tend to be high, and over time, the machine more with more long, the temperature will be higher and higher.
Wick lubrication depends on the capillary wick and siphonage drew the lubricating oil in the oil cup to the bearing, mainly used for the peripheral speed is less than ~ m/s in the light load and load bearing, moreover wick in the whole process can have the effect of filtering.
If there is still a jam, adjust repeatedly, until the reducer to adjust to the axis of rotation flexibility, no obvious axial channeling is preferred, shaft end fixed, fixed end winding way, the end winding shaft system structure is more complex, but allows the shaft system has larger thermal elongation.
The garage and flow butter is not more intellectual personnel, itself has no culture, also never received lubricant manufacturer and equipment manufacturer's technical training, every day in doing the dirty and tired of living itself also does not have the opportunity to learn and ideas.
So maintenance regularly to bearing when reversing, through the above treatment, most of the motor shaft current, has no harm in essence of electric mechanism.
Look at will know that is composed of calcium soap, compound agent and lubricant, drop point ~ ℃, penetration ~ millimeter, moisture resistance, high temperature resistant, can be used in ~ ℃.
NSK bearings imported in addition to the quality, is also due to very fine parts, is not only the function of high bearing, assumptions used in the process of using improper, not only cannot achieve the expected function effect, and it's easy to make the bearing damage, we now must pay attention to in smooth.
