cleaning bearings and related department

I hope in the upcoming Ann pulp before, had just opened bearing package
General grease lubrication, without cleaning, direct filling grease. Lubricating oil, do not have general cleaning, but the equipment used or high-speed bearings, etc., use a fresh oil washed to remove rust coating agent on the bearing. Removes rust bearings, rust, so you can not put aside. Moreover, the sealed bearing grease, used directly without cleaning
Bearing installation method, because the bearing structure, with, conditions vary, in general, due to multi-axis rotation, so the interference fit to the inner ring. Cylindrical bore bearings, multi-pressed into the press, or by hot charging method. Cone of the occasion, mounted directly on the tapered shaft, or sleeve installation
When mounted to the housing, generally with more clearance, the amount of interference with the outer ring, usually pressed into the press, or is installed after the cooling method of shrink fit. With dry ice as coolant, shrink with the installation, the moisture in the air condenses on the bearing surface. Therefore, the need for appropriate measures to rust
Here we were again in several models for the case in terms of bearing off his shaker bearing mounting method
First, shaker cylindrical bore bearing installation
(1) pressed into the press method
Small bearings pressed into the press widely used method. The pad pad into the inner circle, with the press quietly and tightly pressed to come into contact with the inner shaft shoulder block so far.
Operation, the best advance in the mating surfaces oiled. Beat with a hammer as a last resort with the installation, to be on the inner ring mat pad operations. This practice often become the cause of bearing operation, so only used the surplus quantity is small, large amount of interference can not be used, or in large bearings.
Such as deep groove ball wind turbine earing like the non-separable bearings, inner and outer rings are required amount of interference the installation, use the pad mat, with a screw or hydraulic, will push both inner and outer. Aligning ball bearing outer ring easily tilt, if not an interference fit, it's best to install the pad spacers.
Such as cylindrical roller bearings, tapered roller bearings like the separation of bearings can be enclosed within the outer ring are mounted to the shaft and housing, will be installed when combined inner and outer, the key is firmly Both places will be closed, so that they are no deviation from the center, barely pressed membership cards injury caused raceway

In order to ensure safe and reliable operation of the pitch bearing

Wind turbine pitch wind turbine bearing grease selection
In order to ensure safe and reliable operation of the pitch bearing, the work in pitch bearing to minimize friction and wear, avoiding the pitch bearing and the inner surface of the ball channel failure, the bearings must be lubricated. Bearing lubrication and cooling, dust, rust, sealing, cushioning and so on.
Bearing lubrication can be divided into two kinds of grease and oil lubrication. To prolong the life of the pitch bearing, the bearing must be based on the conditions of use, the adoption of appropriate lubrication. Grease has good adhesion is not lost, does not drip, compression resistance, sealing against dust resistance, good corrosion resistance and other characteristics. In the low, medium, medium temperature, high load bearing operation using very common. As the pitch bearing condition is a high load, low speed, the pitch of the bearing means are lubricated with grease. Grease is a base oil, thickener and additives between the between the solids and semi-fluid lubricant. In the content of the grease base oil accounts for 80-95%, and only when under pressure grease base oil from the grease to lubricate the flow effect, when the pressure is removed, grease base oil can be re-absorbed, grease lubrication performance is determined by the performance of the base oil. Grease consistency (from soft to hard) inside grease thickener is determined by the number, the liquid may contain only 2% of grease thickener, and the thick grease may contain from about 20% of the thickening agent. The content and type of additives to form a variety of different characteristics of grease, bearing grease are commonly used calcium based grease, sodium grease, sodium calcium based grease, lithium grease, aluminum grease disulfide molybdenum grease and so on.
A pitch bearing according to the actual conditions, the selection of the pitch bearing grease are taken into consideration fat types of additives, the viscosity of oil, grease dropping point,; E13N oil pumping performance and other properties of the needle penetration.
