Do not directly hammer the bearing surface and non -bearing surface when installing. You should use compression blocks, sleeves, or other installation tools to uniformly stress the bearings. Do not install it by rolling. If the installation surface is painted with lubricating oil, the installation will be smoother. If the conjunction of a large impact, put the bearings into the mineral oil to heat up to 80 ~ 90 ° C as soon as possible, strictly control the oil temperature does not exceed 100 ° C to prevent the hardness of the fire recovery effect and the recovery of the size. When disassembling difficulties, it is recommended that you use the disassembly tool to pull the heat on the inner ring with the heat on the inner ring. The heat will expand the inner ring of the bearing and make it easier to fall off.
Not all bearing requires the minimum working gap. You must choose the appropriate gap according to the conditions. Among the national standard 4604-93, the rolling bearing radial gap is divided into five groups, 2 groups, 0 groups, 3 groups, 4 groups, and 5 groups. Basic radial gap group is suitable for general operating conditions, conventional temperatures and commonly used transmission coordination; bearing at high temperature, high speed, low noise, low friction and other special conditions should be used. Small radial gaps should be selected for precision spindle, the main shaft of the machine tool; the roller bearings can be kept in a small amount of working gap for the roller bearings. In addition, it does not matter the separate bearing; in the end, the working gap after the bearing installation machine is smaller than the original gap before installation, because the bearings must bear a certain load rotation, as well as the cooperation and load generated by the bearings and loads. Elastic deformation.
For seal defects with embedded seal bearing, there are two steps that need to be strictly carried out during the adjustment process.
1. The inlaid sealing bearing covering structure is changed to both sides of the bearing. It is adjusted from the equipment bearing installation structure. There is no need to contact the bearing directly. This structural sealing effect is higher than the bearing sealing of the bearing agency sales, directly blocking the invasion path of granular substances, and ensuring the cleaning inside the bearings. This structure enhances the heat dissipation space of the bearings and has less damage to the anti -fatigue performance of the bearings.
2. Although the bearing external sealing method is good, the heat dissipation path is also blocked, so cooling parts need to be installed. The cooling device can reduce the operating temperature of the lubricant. After cooling, heat dissipation through naturally, which can avoid high temperature operation of the bearings.
