Bearing installation methods: push installation method and thermal installation method, installation method does not apply to other bearing bearing installation, such as the hydraulic method, cold installation method. General hydraulic laws apply to installation of large-scale and non-bearing; cold installation method applies to small and medium non-bearing installation. Both installation methods to install the bearings will result in minor injuries. Compared to push installation and heat installation, damage to the bearings may be ignored are not recorded, is a prerequisite for proper operation. Push install method mainly using the characteristics of bearing its own clearance, installed by extrusion combined with the bearing and applies to small and medium sized bearings heat installation method uses the scalable performance of the bearing material itself, installed by bearing thermal expansion effects, mainly applied to large or very large bearings installed, this method is also suitable for bearing the bulk of the installation.
Bearings using the push installation method and thermal installation method, its bearing bearing installation were considered fit, material properties, and so on. Push installation method is the use of pressure machines or with the bolts and nuts to squeeze the bearing mounting. Structure and functioning of such methods on bearing Raceway surface damage is very small, precision bearings will not have impact about bearing in oil heat install heating in his expansive, then installed in the thermal methodology enables the bearing on the shaft to avoid unnecessary force, complete the installation job in a short time. This method takes advantage of extended expansion properties of bearing steel and even performance, by heating the bearing installed sets of balanced expansion, expanding the size of installation, guarantee the smooth installation of bearing, at the same time ensure the size back, after bearing installation cooling precision is not affected.
Bearing installation two installation method is widely used, so knowing the Notes installation method is necessary: indentation, shall have a bearing size setting pressure value. Push installation, bearing surface must be even, not partial pressure is too great, easy to bring damage to bearings; heat-set method, heat-set oil temperature must not exceed 100 ° c. Bearing non-contact charging oil vessel, avoid bearing intrusion by particles. Bearing best time was 5-10 minutes after the expansion, too fast or too slow is not conducive to the bearing installation. Bearing cover heating oil needed frequent debris clean up, due to replace heating oil.
