Preparation Before Fag Bearing Installation

Fag Bearing Installation

1. Selection and requirements for installation site

The installation site shall be at a distance from lathes, grinders and other mechanical equipment. Fag Bearing Installation The site shall be cleaned and kept dry and clean frequently to prevent iron filings, sand particles, dust and moisture from entering fag bearings.

2. Check fag bearing model and prepare installation tools

Check whether the model and size of fag bearing meet the installation Fag Bearing Installation requirements, select the appropriate assembly method and prepare the tools and measuring tools for installation according to the structural characteristics of fag bearing and various matching parts.

Common installation tools include hammer, copper bar, sleeve, special Fag Bearing Installation backing plate, screw mosquito fixture, press, etc., and vernier caliper, micrometer, dial indicator, etc.

Preparation Before Fag Bearing Installation

3. Inspection of fag bearing assembly surface

If there are bumps, rust layers, wear debris, sand particles, dust and soil on the fag bearing assembly surface and the matched part surface, one fag bearing is difficult to install, resulting in incorrect assembly position; Fag Bearing Installation Second, these attachments form abrasives and are easy to rub the working surface of fag bearing, affecting the assembly quality.

Therefore, before installation, carefully inspect the surface of journal, bearing housing hole, shoulder end face, and the mating surface of connecting parts such as bushing, washer, end, etc. If there is any rust layer, file it off with a fine file and polish it with a fine abrasive cloth. At the same time, remove the attachments on the fag bearing assembly surface and its connecting parts.

When the large SKF Bearing is installed into the disassembly sleeve, it can not only greatly save labor, but also is especially suitable for Fag Bearing Installation occasions where the position is limited and large hook wrench cannot be used. The specific operations are as follows: place the hardened gasket s at the end of the disassembly sleeve,

gently tighten the nut m, and then evenly tighten the hardened bolts K evenly distributed along the circumference until the required clearance reduction is obtained. Since the disassembly sleeve is self-locking by the friction of its conical surface, it will not loosen even if the compression device is removed. In this way, the compression nut M can be safely removed and replaced with a fixed nut to compress the disassembly sleeve.

During installation

a very thin layer of lubricating oil must be coated on the mating surface of the return sleeve to reduce friction and facilitate installation. However, be careful not to apply thick oil, otherwise the disassembly sleeve will lose its self-locking ability. When the compression screw and nut are removed to replace the fixed nut, the disassembly sleeve will loosen and deviate from the set position, resulting in installation error.

In addition, in the working process, the lubricant will gradually be squeezed out or escape from the fitting gap, Fag Bearing Installation resulting in the loosening of the original interference fit of SKF Bearing.

When the installed SKF Bearing is removed and then installed on the journal, the nut cannot be screwed to Fag Bearing Installation the original position as it is, because the original fit of the SKF Bearing System has become loose after a long time of work, which is due to the gradual loosening of the thread,

the permanent deformation of the fitting surface due to pressure, and certain wear due to friction. In this case, the radial clearance reduction, axial thrust or expansion must be re measured during installation. For large bearings, SKF is more Fag Bearing Installation convenient for disassembly and installation.

For all standard disassembly sleeves and threaded shaft ends, the SKF Bearing can also be installed on the conical journal with piston hydraulic nut, or the disassembly sleeve can be pressed into the predetermined position of the cylindrical journal.

The composition and working principle of the piston hydraulic nut are as follows: with the help of the manual oil pump, the pressure oil pressure is fed into the oil cylinder (nut) through the high-pressure hose, the oil cylinder is fixed on the threaded shaft end with its internal thread, the extended end of the piston is pushed on the end face of the inner ring of the SKF Bearing,

the pressure oil drives the piston to push the SKF Bearing forward along the conical journal, and according to the pressure of the oil pressure gauge in the pipeline, The thrust of SKF Bearing can be roughly judged.
