High Standard/Quality Long Using Time Spherical Roller Bearing 23064 Ccw33 with Steel Cage
The pretightening force of the roller bearing is carried out at room temperature, but the pretightening force of the bearing will change in the working state, and the driving shaft of the bearing will change. Therefore, the pretightening force should be taken into consideration.
It requires the ability, size, speed, and other conditions to set the proper use of the roller bearing preload to ensure the transmission of life. If the preload is too high, the power consumption will even lead to overheating. If the pre tightening force is too small, the body load, the shaft rolling, and the gap between the outer rings, produce beating, running, transmission precision, to reduce noise increase, affect gear meshing, serious damage, teeth and bearings.
According to the assembly of different adjustable roller bearings, for example, the bearing pre tightening nut of the inner ring of the inner bearing is rotated and the inner and outer ring is directly compressed to eliminate the gap, and to realize the bearing pretightening force. To achieve common use: first, it is far ahead of the pre loaded bearings, the last of the nuts, and then back to 1 / 4 circles. The advantage of this method is that the tapered roller bearings can be used on the premise of less investment, simple, practical and consistent good quality.
1. heating plate heating method can be placed on an electric heating plate with a temperature of 100 degrees C for a few minutes. This method is the most convenient. If a few times over, the shaft can be heated evenly and the efficiency is high. This method can be used for the size of the roller bearing.
2. the electric furnace heating method is used to heat the bearing in a closed automatic temperature controlled electric furnace. It is uniform in heating, accurate in temperature control and fast in heating. It is suitable for a batch of occasions to heat many bearings.
The 3. induction heating method can quickly, reliably and cleanly heat the adjustable roller bearing to the required temperature by using the induction heater. This is especially suitable for the tight fit of the inner ring, because the heating is only the inner ring, and the outer ring is heated very little, so that it can be easily installed on the shaft and easily loaded into the seat hole.
4. light bulb heating method uses the 50W lamp bubble to heat the adjusting roller bearing. The heating temperature can be guaranteed to be around 100 degrees C, the smaller bearing can be placed directly on the bulb, the larger bearing can be placed in the cone cover of the bulb, the cone cover can prevent the heat loss of the bulb, and the uniform heating can be adjusted on the top and bottom of the conical cover and can be used in a certain range. If the bearings of different sizes are used, the direction of the light bulb should be down, so that the direction of the light bulb should be down, so that the light bulb of the light bulb is not good for the eyes of the human being.
The 5. oil tank heating method is a more widely used traditional heating method. The metal net is set at the bottom 50~70mm of the tank distance. The bearing is placed on the net. The bearing should not be placed directly at the bottom of the groove with the hook of the large bearing. The use of non corrosive thermal stability of the mineral oil, the best is the transformer oil, oil and containers should keep the capacity of the clean oil tank and the size and oil of the heating roller bearing. If the container is too small, the temperature of the bearing oil will drop very quickly in the continuous operation, and the effect is not good.
