Product Description
Parallel-shaft/Right-angle/L-type gearbox
This is a miniature gear reducer featuring multiple configurations including parallel shaft, right-angle, and L-type designs. Centered around the 4GN series as its core model, it employs a precision gear transmission structure that directly interfaces with miniature variable-speed/stepper motors. By leveraging the speed reduction and torque multiplication of its gear sets, it converts the motor's high-speed, low-torque output into the low-speed, high-torque output required by equipment. Characterized by compact structure, flexible installation, and stable transmission, it serves as a core power component for small automation equipment and lightweight transmission applications.
Functional Features
Multi-Structure Adaptability
Offers multiple configurations including parallel shaft (4GN standard), right-angle output, and L-type angular versions. This accommodates diverse equipment layouts such as linear transmission and 90° angular power transfer, enabling precise power transmission design for various small devices without additional adapters.
High Transmission Precision and Stability
Features precision-machined gear sets and high-strength housings with minimal gear backlash. Operates with low noise and vibration, maintaining stable transmission efficiency during prolonged high-frequency start-stop cycles. Ensures precise equipment motion and prevents failures caused by transmission errors.
Compact and Lightweight Design
Its small size and light weight eliminate the need for complex installation space. It can be directly integrated with micro motors, saving equipment layout space while reducing the overall load of the machine. It is particularly suitable for miniaturized and lightweight equipment design requirements.

Application
Compact Automated Inspection Equipment
In electronic component appearance inspection systems, right-angle gearboxes paired with micro stepper motors drive the precision linear motion of inspection platforms. The L-shaped corner structure adapts to compact equipment layouts, while high transmission accuracy ensures smooth, offset-free platform movement. This enables vision inspection systems to accurately capture component details, boosting inspection efficiency and accuracy.
Smart Home Motorized Curtain System
Parallel shaft gearboxes (4GN series) integrated with silent motors deliver stable power output for motorized curtains. Their compact size allows concealment within curtain tracks, while lightweight design prevents track deformation under load. Low-noise operation maintains home tranquility, enabling smooth curtain opening/closing and precise positioning.
Parcel Sorting Machine Scanning Module
An L-shaped gearbox drives the scanning module's reciprocating swing mechanism. Its 90° angular structure perfectly accommodates the module's vertical layout requirements. Highly stable transmission ensures the scanner head clearly identifies parcel barcodes even during high-speed swinging. The compact structure also enables denser module layouts within the sorting machine, increasing the number of parcels processed per unit time.
