What are the two installation methods of spherical roller bearing?
Clicks:15274 Date:11-21
Spherical roller bearing consists of an outer ring, an inner ring, a set of steel balls and a set of retaining structures. It has simple structure, easy to use and so on. For the installation of spherical roller bearing, I believe many users are not very familiar with it. Below we follow Yiyang Longma bearing limited technical staff together to learn spherical roller bearing installation.
Installation method
Press fit method:
1, bearing inner ring and shaft closely, outer ring and the bearing hole with Jiaosong, can press bearing pressure mounted on the shaft, and the shaft together with the bearing load in the bearing hole, pressing on the end surface of the inner ring, a soft cushion assembly sleeve made of metal material (copper or steel).
2. The outer ring of bearing is closely matched with the bearing seat hole. When the inner ring and the shaft are loosely matched, the bearing is pressed into the bearing seat hole first, and then the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole. If the bearing ring and the shaft and hole are tight fit, install the inner and outer rings and pressed into the shaft and hole structure, the assembly sleeve should end compressing bearing inner ring and outer ring at the same time.
Two. Heating matching method:
By heating the bearing or bearing seat, it is a common and labor-saving installation method to use the thermal expansion to change the tight fit into loose fit. This method is suitable for a large amount of surplus bearing installation, hot charging before the bearing or separable bearing rings into the tank in the uniform heating of 80-100 DEG C, then removed from the oil as soon as possible fitted to the shaft, to prevent cooling after the end face of the inner ring and shaft shoulder joint is not tight, the bearing cooling can be axially fastening. This method can avoid the abrasion of the mating surface.
With oil tank heating bearings, from the bottom at a certain distance should be a mesh, or with a hook hanging bearing, bearing can not be put on the bottom, to prevent contaminants from entering the bearing or uneven heating, the tank should strictly control the temperature thermometer, shall not exceed 100 degrees, in order to prevent the occurrence of the tempering effect, make the ring hardness decreased.
Because of the high manufacturing accuracy of spherical roller bearing, improper installation method will not only cause damage to spherical roller bearing, but also reduce the service life. So in the installation is not careless, according to the correct installation steps to install, to ensure the normal operation of spherical roller bearing.
