Inlaid Sprocket Shaft Assembly

Inlaid Sprocket Shaft Assembly

 

Split sprocket shaft assemblies are forged from high-alloy steel, undergoing special machining and heat treatment. This ensures precise dimensional fit, high overall strength, and high wear resistance, resulting in a longer service life. The split sprocket shaft assembly consists of upper and lower halves, facilitating disassembly without moving the headstock. This allows for convenient and quick replacement or reversal of the sprocket, improving efficiency. Simultaneously, it eliminates the need for complete disassembly when replacing or reversing a solid sprocket, preventing damage to bearings and seals, wasting time and labor, and delaying the timely use of the scraper conveyor. Therefore, split sprocket shaft assemblies offer convenience, increased efficiency, and reduced maintenance costs, representing the future direction of sprocket shaft assembly development.

 Superior lubrication and heat dissipation performance

Seven new axial oil passages have been added, increasing the lubricating oil flow rate of both left and right oil chambers by more than five times. The floating oil seal and bearings in the upper part, which are not immersed in lubricating oil, receive ample lubrication and heat dissipation. Data from a 12-hour continuous no-load operation test shows that the highest temperature of the embedded sprocket was 43°C, far below the safe temperature line. No oil leakage or abnormal noise occurred during the process, and the sprocket operated smoothly.

 Upgraded Gear Materials and Manufacturing Processes

The medium-frequency induction hardening heat treatment process utilizes the skin effect of the medium-frequency current to form a hardened layer with a depth adapted to the contact stress distribution requirements of the sprocket teeth and splines. Compared to traditional heat treatment, surface hardness and the depth of the hardened layer are increased, reaching 12-15 mm. The surface wear-resistant layer hardness is 55-62 HRC. The heat treatment process ensures a uniform depth of the wear-resistant layer in the chain groove, a fine and consistent internal crystal structure, significantly improved overall stability and strength, greatly extended service life, and guaranteed safety.

 Modular design with full coverage

The same sprocket base can be adapted to chains with different pitches (e.g., replacing 26X92 and 30X108 tooth blocks), improving the equipment's versatility.

 Link reliability

Precision machining ensures a tight fit between the sprocket teeth and the sprocket shaft. Air is expelled, creating negative pressure, which applies atmospheric pressure to the sprocket tooth surface. Double disc washers prevent loosening, and high-strength bolts, along with preload applied using a torque wrench, guarantee the reliability of the sprocket tooth connection.
