Compact Bore Input Right Angle 90-degree Spiral Bevel Gearbox

● Introduction

A bore-input right angle spiral bevel gearbox features an input shaft with a bore design and a connecting flange plate for direct motor coupling. Its input and output shafts are arranged at a 90-degree angle, achieving power redirection through gear mechanisms such as spiral bevel gears or bevel gears. The core design focuses on optimizing spatial efficiency, making it suitable for industrial automation equipment, CNC machine tools, packaging machinery, and other applications requiring compact installation or directional power transmission. Depending on specific operational demands, housing materials vary: aluminum housings are prioritized for automated systems and weight-sensitive scenarios; stainless steel housings cater to corrosion-resistant environments like food processing, pharmaceuticals, and marine engineering; alloy steel housings are engineered for heavy-duty applications such as smart warehouse lifting systems. Clients must communicate their operational context and material requirements to manufacturers during selection to ensure optimal gearbox performance.

Features

● User-Friendly Design

Features a shaft bore input and a connecting flange for direct motor connection, ensuring ease of use.

● The internal bevel gear structure and perpendicular input/output shaft arrangement minimize equipment footprint, making it particularly suitable for confined installation spaces.

● High Transmission Efficiency and Low Energy Consumption

Employs precision gear meshing and an optimized lubrication system, achieving a transmission efficiency of over 95% while reducing energy loss.

● High Precision and Low Noise

The combination of helical or bevel gears with precision machining results in minimal backlash, accurate positioning, smooth operation, and low noise levels.

● High Load Capacity and Durability

High-strength materials (such as premium forged steel) and heat treatment processes enhance load-bearing capacity, supporting significant radial and axial loads and extending service life.

● Diverse Output Configurations

Available in various output configurations: hollow input with shaft output, hollow input with hollow output, shaft input with shaft output, and shaft input with hollow output.

● Suitable Applications

Ideal for lifting platforms and single-motor driven multi-module systems.
