AI Technical Summary
The tooth structure design of the existing conveyor head wheel results in a fixed stress position in the tooth socket, which leads to severe wear during long-term operation, affecting service life and transmission stability.
The gear is designed with an odd number of teeth, combined with an internal sealing ring and a weight-reducing ring structure. The sealing ring has a sealing convex ring, a wedge-shaped groove, a rectangular groove, and a circular arc groove to enhance the sealing performance. The weight-reducing ring is embedded with ceramic rings, mesh high-strength steel, carbon fiber, glass fiber, aluminum foam, and aluminum alloy materials to improve wear resistance and fatigue resistance.
It achieves a uniform distribution of stress points in the tooth sockets, extends tooth life, reduces the risk of lubricating oil leakage, and improves the stability and durability of the transmission system.

Abstract
Claims
1. A conveyor head wheel tooth profile, characterized by: This structure is suitable for reducing wear on the tooth profile during long-term use, including; The gear body (1) has an odd number of head sprockets, which allows each tooth socket to bear force and extends the service life of the gear teeth. The sealing ring (5) is set on the inner wall of the gear body (1) to maintain the lubrication effect, prevent lubricating oil from leaking from the shaft hole or joint, and reduce wear. Weight reduction ring (3) is located inside the gear body (1) to reduce the weight of the gear and reduce the cost of the gear; Weight reduction hole (2) is set inside the gear body (1) to reduce the weight of the gear, reduce centrifugal force, reduce bearing load, and extend service life.
2. A conveyor head wheel tooth configuration according to claim 1, wherein: The sealing ring (5) has a sealing protrusion (12) inside, which is used to enhance the sealing contact pressure and improve the sealing performance. The sealing ring (5) has a wedge groove (13) inside, which uses a conical structure to self-tighten and fit together to achieve dustproof sealing.
3. A conveyor head wheel tooth configuration according to claim 2, wherein: The sealing ring (5) has a rectangular groove (14) inside, which is used to fix the sealing ring simply and effectively. It is suitable for static sealing applications. The sealing ring (5) has an arc groove (15) inside, which better fits the shape of the O-ring and improves the fit of the low-pressure static seal.
4. The conveyor head wheel tooth configuration of claim 1, wherein: The gear body (1) has multiple sealing rings (5) inside, and the sealing rings (5) are provided with mesh high-strength steel (6), which has both lightweight and support strength effects.
5. The toothed structure of a conveyor head wheel according to claim 4, characterized in that: The sealing ring (5) is provided with carbon fiber (7) inside, which significantly reduces weight while enhancing fatigue resistance and stiffness. The sealing ring (5) is provided with glass fiber (8) inside.
6. A conveyor head wheel tooth configuration according to claim 1 wherein: The sealing ring (5) is provided with aluminum foam (9) inside, which has a certain buffering performance, can reduce weight and absorb vibration. The sealing ring (5) is provided with aluminum alloy (10) inside, which improves the local wear resistance and service life of the gear.
7. The conveyor head wheel tooth configuration of claim 1 wherein: The upper surface of the gear body (1) is fixedly connected with reinforcing ribs (4) to improve the torsional and bending strength of the gear body and prevent structural fatigue or deformation caused by hollowing.
8. The conveyor head wheel tooth configuration of claim 1 wherein: The weight-reducing ring (3) is equipped with a ceramic ring (11) inside, which improves wear resistance and load-bearing capacity, and is suitable for the high wear resistance requirements of conveyor head gear teeth.
