Dein erstes Forum » The Causes Of INA Drive Bearings Failure

INA drive bearings are a bearing adopting thin grease and oil haze lubrication approach, and it is a vital element in contemporary equipment as well as devices. The main function is to sustain the mechanical turning body, reduce the rubbing coefficient during its activity, and also guarantee its rotation precision.

1. Prior to setting up the bearings on the shaft, you should firstly get rid of the dealing with pin of bearings jacket, and at the same time, polishing the surface area of journal to smooth and also tidy, and also apply oil to prevent corrosion as well as lubrication at the journal (permit the bearing to rotate a little on the shaft).

2. Lubricate the bearings seat and also bearing mating surface, and also install the INA bearing in the bearings seat. Then put the setup bearings on the shaft along with the bearing seat. Press to the required setting for installment.

3. Do not tighten up the bolts that take care of the bearing block initially and make the bearing coat revolve in the bearing block. At the same time, install the bearing and also sit on the other end of the very same shaft, transform the shaft a few times, and let the INA bearing itself fix the placement automatically. After that, tighten up the bearing seat screws.

4. Mount an eccentric sleeve. First, the eccentric sleeve is put on the non-traditional step of the bearing inner sleeve and tightened by hand in the direction of shaft rotation. Then place a tiny iron rod as well as a press against the counterbore on the eccentric sleeve. Using the hammer to touch the tiny iron rod in the turning direction of the shaft. Make the eccentric sleeve firmly installed, and finally tighten up the hex screw on the eccentric sleeve.

The Causes Of INA Drive Bearings Failure
Cause of issue

1. Failure of INA drive bearings

The extreme damages of INA thrust bearings are typically not brought on by a single function, but under the consolidated impacts of a number of elements, a vicious cycle is produced under severe operating conditions, resulting in severe burnout of the bearings For that reason, it is commonly difficult to figure out cause after a crash. What creates it will certainly also bring us some difficulties in developing related procedures. For the ease of discussion, we will assess the source of birthing failure from several facets.

2. Unusual wear of INA bearings.

When the INA bearing is made use of for a time, the internal bearing ring, rolling elements, cage, external ring, raceway, and so on have particular issues and also scars, causing inadequate lubrication of the bearing, causing the birthing to create warm, and prolonged heating will certainly create:

( 1 ). Dilution of bearing lube.

( 2 ). Accelerate the tiredness of material and also lower the hardness. Because of the above reason, a vicious cycle is further developed, which increases getting too hot as well as creates the bearings to wear out. Extreme bearing inner ring variation, rolling aspects out of round, impact warmth, and also lastly bonded together. Consequently, when running on the line, if the bearing is located to be very warm as well as smoke, do not quit it. Rather, maintain going to the initial station, because the overheated bearing is in a liquified state at this moment. Once it is cooled, it can no longer walk and also block the mainline.

The Causes Of INA Drive Bearings Failing

3. Influence of installation on bearings

The disturbance gap in between the inner ring of the INA imported bearing, and the shaft does not match, and also it is also very easy to trigger birthing failing. The huge disturbance amount is most likely to create the bearing inner ring to crack due to too much tensile tension, as well as the disturbance amount is as well tiny. It is simple to generate the bearing inner circle to "loosened.".

Improper setting up of bearings and clearances can likewise cause birthing failures. Level removals can conveniently cause frictional heating of rollers as well as raceways. As the temperature level continues to climb, the bearing inner ring, rolling elements, cage, outer ring, end cover.

The temperature is not the same, there is a temperature difference in between each other, so the development amount is also slightly various, which will certainly cause the further decrease of the healthy clearance, and according to the bearing's warmth generation.

If the permission is too big, the resonance of the roller will certainly enhance, which will certainly intensify the impact of the roller as well as a raceway. At the same time, it will conveniently trigger uneven interior lots distribution, reduce the load roller, as well as overload the main roller.
