Industrial fine grinding mill with the rolling bearing, in our country has been widely promotion, power consumption, increase production in save, save the lubricant, reduce maintenance quantity, reduce pollution and so on many aspects, received a good effect. At present some manufacturer follow the rolling bearing grinding machine, the method of hollow shaft and in rolling bearing of the installation of the form is not more shortcomings, to grinding machine manufacturers in the use in future work in operation brings some drawbacks. FAG bearing in order to solve this problem, we put forward the hollow shaft grinding machine, installation of rolling bearing best assembly method.

Mill hollow shaft installation of rolling bearings is hollow shaft old method will be processed into suitable for the inner diameter of the bearing, the bearing hot device, bearing parts, bearings inside the external has a set of rings, top, set in and out of the material by spiral tube (or in and out of the material bushing) bolted in hollow shaft, the pressure. In grinding operation process, in and out of the material cylinder, the retaining bolt spiral often, become loose, caused the top set and the hollow shaft produce displacement, dust will go to empty shaft and the gaps between the set top box to bearing, make a grease gets dirty, lead to bad lubrication, cause the damage of the bearing frequently occurred.

In order to overcome the above several shortcomings, we after years of practice and exploration, INA bearing designed a new installation method, and in some use manufacturer to get a good application. The method is: in the mill hollow shaft installation of rolling bearing parts will be bold in diameter, hollow shaft is the cooling of the thin oil hollow shaft and transmitted to the temperature on the bearing down to 60 degrees below normal range. The advantages of the bearing in the following aspects:

1. Thin oil lubrication grease lubrication is superior to, make bearing to minimize friction coefficient, power saving effect is better.

2. The normal operation of the bearing temperature than dry lubricating oil bearing temperature is much lower, and prolong the service life of the bearings.

3. The oil has a bearing a observation oil mark, operators can see oil a height, can prompt added the amount of oil, prevent for lack of oil and bad lubrication, to avoid the bearing damage accidents.

4. Oil chamber of the bearing oil content, NTN bearing can install of rolling bearing outside diameter narrow (in ensure the installation in and out of the feeding devices have enough strength and torque force under the premise of), hollow shaft and in and out of the material tube connection set one end spiral flange, and in and out of the material spiral tube flange for the link. In the hollow shaft from coarse to fine change of end, set a pressure within the flange bearing collar, prevent bearing axial appear.
