INA bearing installation method

INA bearing installation: INA bearing installation is correct, affecting precision, long life, a performance. Therefore, design and assembly department for the installation of the INA bearing to fully research. Hope according to the standard installation work. The project operation standard usually are as follows:

(1) cleaning INA bearing and INA bearing connection parts;

(2) check the size of the associated parts and precision processing situation;

(3) installation;

(4) installed INA bearing the check after;

(5) supply lubricant.

Hope that in the coming before installation, have opened the INA bearing packaging. General grease lubrication, not to clean, direct filling grease. Lubricating oil, also need not ordinary cleaning, but, with the high speed with INA instrument or bearings, to wash with clean oil, remove coated in the INA bearings rust-proofing agents. Remove rust INA bearing, easy to rust, so cannot place no heed. Moreover, already sealing grease into the INA bearing, not to clean use directly. INA bearing installation method, because INA bearing structure, cooperate, conditions and different, generally, it is because for axis rotation, so inner circle over surplus to cooperate. Cylindrical holes INA bearing, multi-purpose pressed into the press, or use hot charging method. Cone hole occasions, installed directly to the taper axis, or with the sleeve installation.

Installation to shell, with general clearance, outer ring had surplus quantity, usually with pressed into the press, or have after cooling method of installation with cold. With dry ice for cooling agent with the occasion of installation cold, moisture from the air will be condensed in the surface of the INA bearing. So, need appropriate antirust measures.

INA bearing the removal of skills

INA bearing remove to and installation also carefully. Note no damage to the INA bearing and the parts, especially with the interference INA bearing down, and the operation is difficult. So, in the design phase prior to consider to facilitate the removal, according to need to remove the tool design also is very important. In the disassembly, according to research removal methods, drawing order, the investigation of the bearing INA with conditions, in order to achieve the remove homework correctly.

1, the removal of outer ring
Remove interference with the outer lane, in the case of circles set several outer extrusion screw use screws, one side is equal to tighten the screw, part removal. These screw hole common cover blind cork, tapered roller bearing the separation of the INA bearing type, the crust block shoulders set several incision, use spacers, remove with the press, or the gently remove.

2, cylindrical holes of the bearing is removed
The removal of inner circle, can use pressure machinery pull out the latest simple. At this time, it is important that the inner ring bear the pull force.

Large INA bearing the inner circle remove hydraulic method. Through the Settings on the shaft to hydraulic oil hole, in order to make easy to pull out. The width of the bearing is INA large hydraulic method and pull out and fixture, remove the homework.
NU type fuel outlet, NJ type cylindrical roller bearing the inner circle remove can use induction heating. In a short time, heating local, make the inner circle drawing method of the expansion.

3, cone hole of the bearing is removed
Remove the comparison with tight set set small INA bearing, use fastening on the shaft gear ring in support of, will turn the nut several times, use pad is beating remove with a hammer.
Large INA bearing, using hydraulic remove more easy, in the cone hole on the shaft of the oil hole pressure to send oil, making the inner ring inflation, remove the INA bearing method. The operation, have INA bearing suddenly emerge may, had better be to use as a file of nuts.
