Manufacturer of special accessories for 1830 ball mill pinion gear and large ring gear

The ball mill gear adopts an automatic oil spray lubrication device, and the grease is sprayed to the meshing part of the gear. This improvement only requires moving the automatic nozzle head to the point before gear meshing, fixing it on the gear cover, and connecting the oil pipe. In order to prevent the impact of gear cover vibration on the oil pipeline, it is best to use a section of hose for the nozzle head and oil supply line system. Grease is sprayed regularly before the gears enter meshing, and is promptly brought between the teeth for extrusion. It sticks to the tooth surfaces to form a lubricating oil film, which improves the lubrication conditions of the gears and prevents grease from splashing. This effectively extends the operating life of the gear and saves grease. However, the grease sprayed for a long time cannot be recovered and accumulates in the gear cover, so the gear cover needs to be cleaned regularly. This method is mostly used in some heavy-duty ball mills, such as large slurry mills, cement mills, etc. . Use lubricating oil instead of grease. It must be continuously sprayed before the gears enter meshing to form a lubricating oil film. No matter how the grease is added, it rotates with the gear. Most of the grease is thrown toward the gear cover under the action of centrifugal force, drips to the gear during the vibration of the gear cover, is thrown toward the gear cover, and finally falls onto the gear. At the bottom of the cover, the lubrication conditions of the gear are poor, and dry friction or boundary friction will occur at the local meshing point of the tooth surface.
Generally, there are gear teeth, tooth grooves, end surfaces, normal surfaces, tooth tip circles, tooth root circles, base circles, and indexing circles.
Gear teeth
, referred to as teeth, are each raised part on the gear for meshing. These raised parts are generally arranged in a radial pattern. The teeth on the paired gears contact each other, which can make the gears continue to work. Engagement operation.
, tooth space
, is the space between two adjacent teeth on the gear. The end surface is a plane on the cylindrical gear or cylindrical worm that is perpendicular to the axis of the gear or worm.
, end face
, are the flat surfaces at both ends of the gear.
, normal surface
, refers to the plane perpendicular to the gear tooth line.
