Bearing with good can reduce the probability of damage

Bearing durable - at ease Self-aligning roller bearing electricity department author for your explanation: bearing with good can reduce the probability of damage: is to make the bearing of the stationary ring and rotating ring and stationary part of the installation site ( Usually bearing) And rotating parts ( Usually the shaft, Consolidation in together, so as to realize in the condition of rotating relative to the static load and limited movement system the basic task of the system location. In the shaft and bearing, roller bearing requirements in the radial, axial and tangential direction to three directions such as fixed position. Through the positioning of the radial and tangential the tight fit of bearing ring, the axial positioning only in a few cases with tight fit; Generally USES the axial spacing parts, such as end cover and retainer could happen on the axial location clearance range. Choosing cooperation should focus on the following four: ( 1) Bearing ring circumferential surface should have good bearing and force uniform, in order to reduce the deformation, and can give full play to the bearing capacity of the bearing. ( 2) Ring in its surface can't slide along the tangent direction, otherwise it will damage the mating surface. ( 3) Freedom end bearing must be able to adapt to changing with the length of the shaft and bearing seat holes, which must have to adapt to the axial location within a certain range of swimming ability. ( 4) Must pay attention to the bearing installation and easy disassembly, saving time and expenses for the province. About bearing damage status, such as: roller bearing ring, guard card injury, as a reason to consider, lack of lubricant, not suitable for, for the defect of oil discharge structure, the invasion of the foreign body, bearing installation error, the deflection of the shaft is too large, also can have these reasons. Therefore, only investigate bearing damage, the real reason is hard to come by injury. But, if you know the use of bearing mechanical and conditions of use, bearing the surrounding structure, understand before and after the accident, combined with several damage status and causes of bearing, can prevent the similar accident happen again. Bearing with good can reduce the probability of damage: bearing judgment: imports of spherical roller bearing is available, mainly considering bearing damage degree, mechanical properties, importance, and operating conditions, to the next overhaul period. If there are the following defects cannot be used again, new bearing must be replaced. Inner ring and outer ring, rolling element and cage on any one have crack or gap. 1, ring, rolling body fracture on any one. 2, rolling on the pavement, guard, rolling body CARDS have a significant injury. 3, keep wear significant or rivet significant relaxation. On page 4, raceway and rolling body rust, injury. On page 5, raceway and rolling body severe creasing and mark. 6, inner ring diameter or outer diameter surface has obvious creep. 7, due to the hot color change is obvious. 8, the bearing grease sealed, sealing ring or dust cover breakage is obvious. Bearing comfortable and durable, )
