According to the rolling bearing and low-quality simple identification (foreign language translation)

Abstract: the agricultural machinery in use, shall identify the superiority of rolling bearing, in order to reduce unnecessary loss, summarizes several simple recognition methods, and for reference.

Keywords: rolling bearing; Basic structure; Identification method



With the popularization of agricultural machinery, and use some of the pusher farmers revision, will cast psychological factory waste bearing the processed sales to the country, to the agricultural production to cause major damage. Now the rolling bearing the basic structure, the corresponding function and several recognition and rolling bearing and simple method are presented here.

1 the rolling bearing the basic structure and the corresponding role

Based on sliding bearing developed rolling bearing, the working principle is based on the rolling friction is instead of sliding friction is general by two front-runners, 1 group and a roller keep frame of generality, standardization and serialization strong degree very high mechanical foundation a [1-2]. Because of the mechanical work conditions and different rolling bearing load capacity in, the structure and the use of performance and so on are put forward different requirements. But its most basic structure is the inner ring and outer, rolling body and keep frame composition. Its corresponding role for: for to the heart bearings, inner ring and shaft with tight, usually and to work together and axis, outer shell with housing or mechanical usually cast-in-place transition, the supporting role with. However, in some cases, also have outer and inner circle operation fixed up supporting role within the inner circle or both of the operation. For thrust bearing, and axis and together with the movement with tight circle, and housing says shaft or mechanical shell transition cooperate and support the cast-in-place the role of a circle says. Rolling elements (steel ball, roller or needle) in bearings inside keep frame evenly with usually arrange them in two front-runners between rolling motion, its shape, size and number of direct influence on bearing load capacity and performance. In addition to keep frame can be evenly roller separated beyond, still can play guide roller rotation and improve internal lubrication effect such as performance bearing [3-4].

2 simple test methods

2.1 the eye view feel method

One is the eye view. First appearance, check bearing see have formal factory, no label the mark for not qualified products. Then, wash off bearing outer packing of the grease, …………
