Ultrafine Mill Transmission Failure

How To Solve Ultrafine Mill Transmission Failure?

The transmission device is one of the main parts of the Ultrafine Mill. During the operation of the Ultrafine Mill, there are many problems, such as tooth wear, gear breakage, gluing and plastic deformation, which means the transmission device fails. The analysis shows that the failure of the transmission device is related to the working environment and lubrication, the installation, maintenance and manufacture of the gear. In order to solve the problem of transmission failure, different measures can be taken for different reasons.

1. Improve the lubrication system


Change the lubrication method and change the artificial lubrication to the automatic injection lubrication. Besides selecting the open type gear oil with high quality and fully satisfying the lubrication requirements of the Ultrafine Mill drive gear, the oil quality monitoring should be strengthened. In the operation, should strengthen the inspection and supervision of oil lubrication system of Ultrafine Mill, to filter impurities and moisture, so as to ensure the lubrication effect, at the same time through the transmission gear will shield by semi open to closed, reduce dust particles into the gear meshing area, mixed into the lubricating oil, to ensure the quality of lubrication oil. At the same time, the influence of seasonal temperature change on the viscosity of lubricating oil should be considered.

Check the oil amount in the oil tank regularly, check the connection lines, components and related seals to prevent the occurrence of oil leakage.

2. Other aspects

Install strictly according to the installation standard. Especially the gap in reverse gear should pay more attention to the radial and end surface measurement of the big gear ring runout, gear ring and cylinder after the installation of the concentricity, the big gear ring etc.. Then, the "lead pressure" method is used to measure the meshing backlash with the pinion, and the parallelism between the pinion axis and the center line of the cylinder. After all the tests are qualified, the test run can be carried out.


In peacetime, we should strictly implement the system of equipment inspection. The maintenance standards are strictly carried out during overhaul to ensure that the components meet the assembly size requirements after overhaul. After running for a period of time, the Ultrafine Mill equipment should have the key dimensions, such as gear clearance, parallelism of pinion axis and center line of the cylinder, the coaxality of pinion shaft and motor shaft, etc.

The lubrication system after the transformation, the lubricating oil evenly to the filling time quantitative lubricating parts, effectively control the oil consumption, both to ensure the oil supply is sufficient, but also avoid the oil shortage, also played a good shock absorption, impact resistance, prolonging the service life of the gears. The use of closed cover can guarantee the reduction of gear wear and prolong the service life of the gear.
