Taper Lock Sprocket

Understanding Taper Lock Sprockets: The Advantage of Easy Mounting

Taper Lock sprockets are a type of roller chain sprocket specifically designed to be used with a Taper Lock® bush system. The sprocket has a tapered bore, and a corresponding tapered bush fits into this bore. When screws are tightened, they draw the bush into the sprocket's taper, simultaneously clamping the bush tightly onto the shaft and locking the sprocket securely to the bush.

How Taper Lock Works:

• Tapered Bore Sprocket: The sprocket features a precisely machined internal taper.
• Tapered Bush: A split, tapered bush matches the sprocket's bore. The bush has a straight bore sized for the shaft and includes threaded holes.
• Mounting Screws: Screws pass through unthreaded holes in the sprocket hub and engage with the threaded holes in the bush. Tightening these screws pulls the bush into the sprocket's taper.
• Secure Clamping: This action creates a powerful friction grip on the shaft and rigidly locks the sprocket axially and radially.

Advantages of Taper Lock Mounting:

• Easy Installation & Removal: Significantly faster and simpler than fitting bored-to-size sprockets with keys. No special tools required beyond hex keys.
• Secure Grip: Provides a strong, concentric grip on the shaft, minimizing vibration.
• No Keyway/Set Screw Needed (on Sprocket): Simplifies sprocket inventory and eliminates potential weak points associated with keyways. (Note: The bush itself requires a keyway on the shaft).
• Interchangeability: Standard Taper Lock bushes are widely available and interchangeable between different components (sprockets, pulleys, couplings) using the same bush size.
• Accommodates Shaft Tolerances: The clamping action can accommodate minor variations in shaft diameter.
• Reduced Downtime: Quick replacement minimizes machine downtime during maintenance.

Considerations:

• Requires Taper Lock Bush: The bush is a separate component that must be purchased along with the sprocket.
• Assembly Length: The bush adds slightly to the overall length of the assembly on the shaft compared to a Type B sprocket.
• Correct Bush & Torque: Using the correct bush size and tightening screws to the recommended torque is essential for proper function and safety.
