| The hinged shaft 20MG20.11.11.98 in the coal mill is an important mechanical connection, and its working principle is as follows: 1. Transfer loading force: One of the main functions of the hinged shaft is to transfer the hydraulic loading force to the grinding roller. This allows the grinding roller to effectively squeeze and grind the coal to improve the grinding efficiency. 2. Roller swing: The hinged shaft enables the grinding roller to swing freely within a certain range. This design allows the grinding roller to adapt to changes in coal seam thickness and achieve better coal pulverization during grinding. 3. Adapt to different angles and positions: The design of the hinged shaft allows the grinding roller to have a certain degree of freedom in the horizontal position and can swing, and has strong adaptability to iron blocks, wood blocks, stones, etc. 4. Force balance: The working principle of the hingde shaft relies on the principle of "force balance". When objects are connected to the hinge shaft, they are subject to external forces. These forces are transmitted to the hinge shaft and dispersed to the entire connection part through the hinge and shaft. If the object is in a state of equilibrium, that is, the external force and the reaction force are balanced, then the hinge shaft can remain stable. 5. Realize the rotation or switch operation of the object: When the external force changes, the hinged shaft will move accordingly according to the direction and magnitude of the force. By changing the relative position of the metal sheet, the hinge shaft can realize the rotation or switch operation of the object. 6. Improve the service life of wear-resistant parts: The fixed hinged shaft is used to support the grinding roller, so that the grinding roller has a certain inclination on the grinding disc. The grinding roller wears on one side during grinding, and has the advantage of swinging, which improves the service life of wear-resistant parts. |
