Taper Lock Mounting – Quick Installation & Secure Fixation
The taper lock (taper bushing) mounting system offers several key advantages over traditional set screw or keyway mounting:
| Feature | Taper Lock Mounting | Traditional Keyway / Set Screw |
|---|---|---|
| Installation | Quick – simple bolt tightening | Time-consuming – key fitting |
| Removal | Easy – remove bolts, tap release | Difficult – may require pullers |
| Shaft Fixation | Secure – friction lock + keyway | Moderate – set screw point contact |
| Axial Locking | Yes – prevents shaft displacement [4†L5-L7] | No |
| Concentricity | Excellent – precision taper fit | Moderate |
| Reusability | Yes – multiple installations | Limited – keyway wear |
| Best for | High torque, frequent maintenance | General applications |
✅ Choose taper lock mounting for applications requiring quick installation, secure shaft fixation, and easy removal for maintenance [4†L5-L7].
Product Structure
Timing Pulley Body – Precision-machined from 45# steel, stainless steel, or cast iron with CNC hobbed teeth.
Taper Lock Bushing (Taper Bush) – Split tapered bushing that provides secure shaft fixation and easy removal [4†L5-L7].
Tooth Profile – Precision-formed teeth matching the belt pitch (HTD, RPP, 8YU, trapezoidal, etc.).
Keyway – Standard keyway for positive torque transmission.
Flanges (Optional) – Guide flanges for belt tracking.
💡 How it works: The timing pulley is mounted on the shaft using a taper lock bushing. The bushing has a tapered outer surface that matches a tapered bore in the pulley. When the mounting bolts are tightened, the bushing is drawn into the pulley bore, creating a secure friction lock on the shaft with a keyway for positive torque transmission [4†L5-L7]. This provides quick installation, secure fixation, and easy removal for maintenance.
