Lubricated general knowledge of the bearing


30th May 2010 Bearing Technology 0 Comments
1.Performance of antirusting The oil used in the bearing has antirusting nature, the rustproof performance quality is mainly the solubility of seeing oil, lubricating grease that different viscosity and different materials formed, have defending holding and performance of antirusting of different grades, the general one will come to say, it is better that the oil with great viscosity and with bad lipid solubility is waterproof, even such oil is full of water in banking up the forest with earth, can form a layer of oil films that can be kept out on the surface of steel products. The bicycle ...

Daily material of gear


30th May 2010 Bearing Technology 0 Comments
The gear relies on one's own physical dimension and material intensity to bear the loaded one outside, it relatively has toughness and wearability of high strength that this requires materials; Because the gear shape is complicated, the gear precision is expected much, require the material craft is good. The daily material, in order to forge steel, casts steel, casting iron. First, forge the steel The hardness is divided into two big classes according to the tooth When the 350 HB<, call it the soft tooth When the 350 H8>, call it the hard tooth l. Hardness HB<350 the tooth ...

1,Washing of the bearing While dismantling the lower bearing to overhaul, record the bearing appearance at first, confirm the remaining quantity of lubricant, after lubricant used for taking a sample to check, wash the bearing. As cleaner, use the petrol, kerosene ordinarily. The washing of the bearing dismantled, divide thickly and wash and wash thinly and smartly, in the container respectively, put the metal network and lag behind, make the bearing not contact the dirt of the container directly first. Thick while washing, if make the bearing take the dirt to rotate, will damage the ...

The single stage form sucks the lubricated way of the bearing of the centrifugal pump and transforms brief introduction


30th May 2010 Bearing Technology 0 Comments
The lubrication of the rolling bearing of the centrifugal pump is mainly reducing and gritting the consumption, reduce the abrasion rate, still play function such as cooling, being dustproof, antirusting and sucking and shaking at the same time. It is to guarantee to do the apparatus well and lubricate the apparatus runs well. Reduce the apparatus abrasion, prevent the apparatus accident, reduce motive force to consume, lengthen the effective measure of repairing cycle and service life. The centrifugal pump that the roaster circulating water system of our factory uses sucks the pump for the ...

The rolling bearing is from making to installation to use its change of backlash


30th May 2010 Bearing Technology 0 Comments
The rolling bearing is backlash with regulation according to the contract during manufacture, this backlash is generally called the primitive backlash; This bearing, while installing on the host computer, because a certain set of circles are full of cooperating, lead to the fact the bearing backlash value is reduced, this backlash formed after installation is named and install the backlash; Through operating, the bearing part temperature is raised, the volume changes ,, Because the rising in the temperature of axle or shell years old of matching bearing extends the phenomenon again, this ...
