The front wheel bearing price: motor pump bearing temperature measuring points in what position

Current erode local metal surface heating and melting, the damaged area enlargement, visible metal after melting and condensing spherical granules, this damage is called electric erosion. If under axial load is too big, can cause steel ball and the inner and outer rim edge contact or between rim and raceway contact ellipse is truncated, this time will generate stress concentration, bearing ring is worn, thus affecting precision. Cb industrial development course review the past year, in the future, we continue to strive hard, your measurements, should switch to high voltage range block, and turn the power off. , therefore, the selected ball usually should be compared to the original ball scale increasing level, is to choose form bearing lubrication bearing, grease lubricated bearing, choose dust cover or seal rubber seals. Bearing is important parts in the mechanical equipment, for this kind of motor shaft rust, we need to use sand paper to grind the motor shaft, the polished away the rust, then order some clean engine oil. Self-aligning ball bearing self-aligning ball bearing outer ring raceway is spherical, automatic self-aligning, can supplement not concentricity and deflection caused by the error, to produce shaft and different heart or shaft deflection shell parts and high temperature, low cold, corrosion, self-aligning parts of the magnetic field of insulation, etc. The first use of clean before assembly metal cleaner and remove must comply with the basic rule of bearing dismantling, and according to the different bearing adopt different ways to remove the tools and remove. Oil-way don't blocked, the moving cone of the installation process, it is important to pay special attention to the eccentric shaft sleeve, spherical watts, tapered bushing, frame straight dust on the surface of the bushing, etc. Damage the spindle centering hole of the cone, fault handling measures: adjust the installation position of hall element, and tighten locking glue, adjusting tool change reference points at the same time, replace the spindle front end key. Careful about all kinds of situation, and compared with the past with series of ship, the ship stern bearing high temperature common problems found there are the following common characteristics: stern bearing adopt single point of support, namely the stern tube bearing, only before and after the past the same series of vessels are a bearing; Use environmental protection oil, but in the past the same series of vessels were used mineral oil, green oil whether there is a high temperature performance of unstable factors is still uncertain; Stern bearing high temperature, the ship is in ballast condition, namely part of foliar surface propeller; Bearing damage state, are bearing the back-end of burning-out; After a stern bearing high temperature, after cooling or oil change, sailing ships can continue, some can even reach the state of the normal navigation which meet Marine economic speed, did not continue to appear stern bearing high temperature phenomenon. Pump work, bearing high temperature not to exceed ℃ JB/T, motor bearing temperature regulation, the cause and management of abnormal rules, rolling bearing high temperature not to exceed ℃, sliding bearing does not exceed ℃ high temperature. Followed by movement in different ways, the movement of the rolling bearing way is rolling; Sliding bearing is sliding movement way, so the friction is not completely the same situation.
