How to install and align the girth gear and pinion

14/01/2020· The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill. In order to ensure their reliable operation, in addition to strengthening the daily maintenance and regular maintenance, the installation and alignment of the girth gear and pinion are also important.

SKF Performance Contracts for Horizontal Grinding Mills

At a cement mill in South Australia, SKF was engaged to conduct a bearing replacement on the feed side. When the old bearing was removed, it was in worse shape than expected. Not only was the bearing failure of catastrophic nature, but the bearing housing and journal were damaged. The housing could not be re-used as it was, and the lead times for procuring a new one would be too long.

Improving Mill Shoe Bearing Reliability and Productivity

And improved filterability over gear oil, providing longer lubricant life, improved filter longevity, and again better oil flow to the bearings. Maintenance Tips. If high bearing operating temperatures cause the mill to trip offline, consider increasing the trip set points. Consult your OEM when doing this, making sure to evaluate the maximum operating temperature for the bearing materials

High Vibration Ball Mill Duel Pinion Drive Mechanical

The Mill Trunion Bearings are at fair vibration As with limited information at this time only the report with a few spectrums and a table of overall velocity reasons it is a bit difficult to get a handle on the issue.

Ball Mill Pinion Vibration Analysis & Machinery

I have an issue with a gear drive on a ball mill. 2XGM is rising and i have sidebands at 107cpm and I don't know why they are at 107 (not relevant to any turning speeds ect.) I checked the root clearance a week ago and the inboard is about a .066 smaller than the outboard. The pinion is 24" long and has 24 teeth. It is obvious i have misalignment.And there is obvious spalling on the gear faces

Graetech RF45 milling machine CNC conversion Repairing

After approximately 40 hours of happy machining with my new RF45 mill, the gearbox slowly developed a loud grinding noise and then after another hour, an oil leak. I experimented with different gears and found that the loud bearing noise depended on what gear I was using to drive the spindle. The cheap Chinese bearings had collapsed in the gearbox, and an oil seal had split! Time to repair it

Questions About Bridgeport J Head Upper Assembly

01/07/2015· Moving up the mill we come to the gear box. Originally, again the bull gear bearings and bull gear countershaft bearings where of the open race design. Mr. Walker did say that Bridgeport did move to sealed bearings for the counter shaft but in a machine that is 40 or 50 years old you would find open race bull gear countershaft bearings. The gear box lubrication is again by filling a gits cup
