Bearing damage and countermeasures

Bearing knowledge lectures: Bearing damage and countermeasures Generally, if the bearings are used correctly, they can be used until the fatigue life is reached. However, there are accidental premature injuries that are not resistant to use. This early damage, as opposed to the fatigue life, is a quality use limit that is referred to as a failure or an accident. Due to inadvertent installation, use, and lubrication, foreign matter that has intruded from the outside is not sufficient for the thermal effects of the shaft and housing. As to the damage state of the bearing, such as the bearing ring of the roller bearing and the rib, it can be considered as a cause. The lubricant is insufficient, the lubricant is not suitable, the defect of the oil supply and drainage structure, the intrusion of foreign materials, the bearing installation error, the shaft deflection If the song is too big, there will be overlapping of these reasons. Therefore, it is difficult to know the true cause of the damage by only investigating bearing damage. However, if you know the use of the bearing machinery, the conditions of use, the structure around the bearing, understand the situation before and after the accident, combined with the bearing damage and several reasons, you can prevent the recurrence of similar accidents.

Handrails play a very important role in the aging of the family. Through a small handrail, create a safe and secure living environment for the elderly at home. When installing the handrail, pay attention to determine the installation height of the handrail according to the height of the elderly at home. The armrest is located at the crotch of the elderly. Generally speaking, it is about 80 to 85 cm from the ground. In order to provide safe and effective support for the elderly, different products need to be selected according to different installation conditions. Some families want to install handrails on non-load-bearing walls. We suggest that they install lining plates first, and then install handrails on the lining plates.

When selecting the material of the handrail, pay attention to the coordination with the furniture environment, create a warm atmosphere, avoid making it cold and hard, and do not give the elderly the illusion of "being a patient". For example, the wooden handrail in the video looks very warm and feels good. It is suitable for the elderly.
