Chain sprocket grain elevator 84981028 New Holland, T9

Compact Structure: Fewer teeth result in a relatively smaller sprocket diameter, facilitating transmission layout within the baler's limited installation space.

Wear Resistance & High Strength: To withstand heavy-duty conditions, they are typically manufactured from Carbon Steel for Machine Structural Use and undergo heat treatment processes like high-frequency quenching on the tooth surface to increase hardness and wear resistance.

Design

Tooth Profile: Usually adopts the standard three-arc-plus-straight-line tooth profile, ensuring smooth chain engagement and disengagement while reducing impact.

Structure: Small-diameter sprockets are often of a solid one-piece structure to ensure overall strength.

Bore & Keyway: The bore typically has an H7 tolerance and is equipped with a parallel keyway to ensure a tight and reliable connection to the drive shaft.

Working Efficiency

High Transmission Efficiency: Chain drive itself is a highly efficient transmission method. For well-maintained and properly lubricated roller chain drives, the efficiency can typically reach 96%

Load Capacity

 Suitable for Heavy-Duty, Low-Speed Applications: The 9-tooth design is a small-tooth-count sprocket, intended for transmitting high torque under low-speed, high-load conditions.

Core Influencing Factors: The actual load capacity depends heavily on the sprocket's material, heat treatment process, and manufacturing precision.
