High-Precision Plain Bevel Gears for Industrial Power Transmission

In the demanding world of mechanical power transmission, achieving reliable and efficient torque transfer at intersecting axes is paramount. Our high-precision plain bevel gear is engineered to meet this exacting challenge. Designed for durability and optimal performance, this gear type is a fundamental component in systems requiring a change in the direction of shaft rotation. Manufactured from premium-grade materials with state-of-the-art CNC machinery, our plain bevel gears deliver consistent, quiet operation and extended service life, making them an ideal solution for a vast range of industrial applications.

Product Overview

A plain bevel gear, also commonly referred to as a straight bevel gear, features straight teeth that are tapered and converge at the apex of the cone. This classic and robust design is renowned for its simplicity, effectiveness, and ease of manufacturing. Our product line encompasses a comprehensive range of sizes, modules, and pressure angles, allowing for precise integration into your existing or new mechanical assemblies. Whether for heavy-duty machinery or precision instruments, we provide a reliable plain bevel gear solution that balances performance with cost-effectiveness.

Frequently Asked Questions (FAQ)

Q1: What is the main difference between a plain bevel gear and a spiral bevel gear?

A: The key difference lies in the tooth design. A plain bevel gear has straight teeth that are tapered, while a spiral bevel gear has curved, oblique teeth. Spiral bevel gears engage more gradually, offering smoother, quieter operation and higher load capacity but at a greater manufacturing cost. Plain bevel gears are more economical and perfectly suitable for many applications with moderate speed and load requirements.

Q2: Can you manufacture plain bevel gears to match my existing broken gear?

A: Yes, reverse engineering is a common service. By providing the damaged sample or detailed drawings/measurements (module, tooth count, pressure angle, bore size), we can precisely replicate or improve upon your original plain bevel gear.

Q3: What information do you need to provide a quotation for a custom plain bevel gear?

A: To provide an accurate quote, please specify: 1) Module or Diametral Pitch, 2) Number of Teeth, 3) Face Width, 4) Material Specification, 5) Required Heat Treatment and Hardness, 6) Bore Diameter & Keyway Details, 7) Required Accuracy Grade, 8) Annual Quantity.

Q4: What are the standard packaging options for international shipment?

A: We use anti-rust VCI paper, plastic caps for bores, and individual plastic bags for each gear. For bulk orders, gears are securely packed in wooden crates or heavy-duty cartons to prevent damage during ocean or air freight. Packaging can be customized per client request.

Q5: How do I ensure proper alignment when installing a plain bevel gear set?

A: Correct alignment is critical for performance and longevity. Key steps include: ensuring shafts are perpendicular and intersect precisely, adjusting the mounting distance so the gear teeth make proper contact across the full face width, and checking the backlash with a dial indicator. Our technical datasheets provide recommended installation tolerances.
