[0002] Screw conveyors are used in pelletizing machines to transport materials. Screw conveyors are devices that transport materials by driving the axial movement of a shaft with spiral blades through its circular motion.

[0003] The bearing seats used in screw conveyors need to bear axial force in most scenarios. Especially when the screw conveyor is arranged at an angle, the axial force on the bearing seat is greater than the radial force under working conditions. The use of standard bearing products with square seat bearings on the market will result in a high failure rate and short life of the bearings.

[0004] Therefore, the utility model provides an axial force bearing specially used for the granulator screw conveying equipment, which can greatly improve the level of axial force by installing tapered roller bearings, bring better stability to the bearings, and provide stable lubrication output to the tapered roller bearings in the bearings, so that the tapered roller bearings can run smoothly and lubricated.

[0007] In a preferred embodiment of the utility model, the straight-through pressure-injection oil cup is detachably mounted on the oil filling hole, and the straight-through pressure-injection oil cup is vertically mounted.

[0008] In a preferred embodiment of the present invention, the bottom of the oil filling hole is formed into an inclined surface and the inclined surface guides the tapered roller bearing.

[0009] In a preferred embodiment of the utility model, a skeleton oil seal is installed on the tapered roller bearing.

[0010] The beneficial effects of the utility model are as follows: the utility model can greatly improve the level of axial force by installing tapered roller bearings, bring better stability to the bearings, greatly improve the level of axial force, improve life, improve bearing reliability, extend the maintenance cycle, reduce the number of maintenance times, and provide stable lubrication output for the tapered roller bearings in the bearings, so that the tapered roller bearings can run smoothly and lubricate, and the lubrication is injected through the connected oil injection holes using a straight-through pressure oil injection cup, so the oil supply is stable and lasts for a long time.
