Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a motion self-supply oil gear comprises an outer ring 1, a plurality of straight teeth 2 are arranged on the outer side wall of the outer ring 1 at equal intervals, the straight teeth 2 are connected with the side wall of the outer ring 1 in a welding mode, at least two oil storage cavities 4 are arranged in the outer ring 1, an inner ring 3 welded and fixed with the outer ring 1 is arranged on the inner side wall of the outer ring 1, an annular cavity is arranged in the inner ring 3, sliding grooves with the same number as the oil storage cavities 4 are formed in one side, close to the outer ring 1, of the annular cavity, bearing plates 7 connected with the sliding grooves in an inserting mode are arranged in the sliding grooves, connecting rods 6 fixedly connected with the bearing plates 7 are arranged on one side, far away from the inner ring 3, of the bearing plates 7, the other ends of the connecting rods 6 penetrate through the inner side wall of the outer ring 1 and are connected with the sliding plates in a sliding mode, fan-shaped, be equipped with a plurality of oil filler points on outer loop 1's the lateral wall, it is equipped with lock oily bolt 10 to insert in the oil filler point, be equipped with oil outlet 11 in the straight-teeth 2,

oil outlet

11 and 4 intercommunications in oil storage chamber, move in inner ring 3 through ball 9, when ball 9 and bearing plate 7 contact, will extrude bearing plate 7, make bearing plate 7 remove to outer loop 1, it overflows to drive fan-shaped push pedal 5 extrusion lubricating oil in oil storage chamber 4 from oil outlet 11 on straight-teeth 2, lubricate the tooth surface of the gear, thereby reduce the frictional force when gear toothing, improve the life of gear, do not need the manual brush oil of workman simultaneously, also need not add the oiling device, it is more convenient to use, reduce use cost simultaneously.

Specifically, as shown in fig. 2, be equipped with the screw hole on the inside wall of oil filler point, lock during oil bolt 10 inserts establishes the screw hole and rather than threaded connection, the cover is equipped with the sealing ring on the lock oil bolt 10, through threaded connection between lock oil bolt 10 and the oil filler point, carry out the shutoff to the oil filler point, add simultaneously and establish the sealing ring, guarantee the leakproofness of oil filler point, when preventing gear use, lubricating oil flows from the oil filler point, carry out the shutoff through locking oil bolt 10 to the oil filler point simultaneously, device simple structure, the convenience is refueled oil storage chamber 4.

Specifically, as figure 1 shows, the cover is equipped with the sealing washer on fan-shaped push pedal 5's the lateral wall, and fan-shaped push pedal 5 and the sealed processing in oil storage chamber 4 are through adding on fan-shaped push pedal 5 and establish the sealing washer, guarantee the leakproofness between fan-shaped push pedal 5 and the oil storage chamber 4, guarantee when fan-shaped push pedal 5 removes, and the lubricating oil in the oil storage chamber 4 can not spill over from the gap between fan-shaped push pedal 5 and the oil storage chamber 4.

Specifically, as shown in fig. 3, both ends of the bearing plate 7 are rounded, and both ends of the bearing plate 7 are rounded, so that the impact force between the balls 9 and the bearing plate 7 can be reduced, and the stability of the gear in use can be ensured.
