PGFUN 1:1 Right Angle Bevel Gearbox (8mm Shaft)
The 1:1 bevel gearbox from PGFUN is designed for simple DIY mechanical applications. It integrates a 1 module, 20 teeth bevel gearset with an 8 mm shaft. The unit supports a maximum torque around 5 N·m (3.6 ft-lbs) and up to 1500 rpm, with a nominal backlash of about 5 degrees. It is suitable for lightweight, compact steering-drive tasks where a direct, right-angled drive is needed. The gearbox can be driven via coupling and belt pulley arrangements to connect to available motors.
ZORZA 1:1 Right Angle Gearbox, 1.25 Module
Built for straightforward DIY mechanical tasks, the ZORZA gearbox features a 1:1 right angle bevel design with a 1.25 module, 20 teeth gearset and a 10 mm inner shaft hole. The compact housing includes two M5 screw holes for secure mounting. Its modest profile (outer diameter ~27 mm) makes it ideal for small robotics or compact motion transfer projects where a right-angle drive is advantageous and space is limited.
1:1 Right Angle Bevel Gearbox, 1.5 Module
The tpengine 1.5 module gearbox provides a 1:1 right-angle reduction with 20 teeth. Built from aluminum alloy and #45 steel, it emphasizes lightweight durability while delivering reliable torque transfer. The unit’s design supports simple mechanical projects and can be paired with standard couplings or belt pulleys to fit a range of motors and shafts. It’s a practical option when a slightly larger module helps achieve desired stiffness and load handling without excessive size.
PGFUN 1:1 Right Angle Bevel Gearbox (8mm Shaft)
This PGFUN model emphasizes a compact 1:1 bevel gear arrangement with 1 module and 20 teeth, featuring an 8 mm shaft. It uses aluminum alloy and #45 steel for a balanced mix of strength and light weight. With a 100 x 75 x 25 mm overall size, it fits neatly into small device footprints and supports motor-driven arrangements via a straightforward coupling or belt drive solution.
uxcell 90 Degree Bevel Gearbox, 1:1, 10mm Shaft
The uxcell 1:1 bevel gearbox offers a 90-degree drive with a single 10 mm shaft. The aluminum frame keeps the unit lightweight while maintaining durability. The 1:1 gear ratio supports efficient torque transfer and smooth rotation, making it a practical choice for small robotic arms, camera rigs, or compact automated mechanisms where space and weight matter.
uxcell 90 Degree Bevel Gearbox, 1:1, 8mm Shaft
The 1:1 uxcell model with an 8 mm shaft provides a compact, aluminum-frame option for small-scale gear-driven connections. Its 20-tooth bevel gearset is designed for straightforward power transmission in DIY projects where quick assembly and reliable performance are priorities. This unit is well-suited for hobbyist robotics and lightweight automation tasks needing a right-angle drive.
Buying Guide: Key Purchase Considerations for Small Right Angle Gearboxes
- Gear ratio and size: Choose 1:1 or near-1:1 configurations for direct drive or minimal speed reduction. Consider module size (1.0, 1.25, 1.5) to match gear tooth engagement and overall dimensions with your motor shaft.
- Shaft diameter and compatibility: Ensure shaft diameters (8 mm, 10 mm) align with your motor output and coupling options. Confirm hole patterns if mounting to frames or plates.
- Torque and speed ratings: Look for a gearbox that supports your load and desired speed. Higher torque is beneficial for stiff loads, while rpm handling determines how fast you can drive the mechanism.
- Materials and weight: Aluminum frames with steel gears balance strength and lightness, aiding ease of handling in compact assemblies.
- Mounting and integration: Check for screw hole counts and positions, including M4 or M5 holes, to simplify secure installation in tight spaces.
- Compatibility with motors and drives: Plan for couplings or belt-driven options to connect the gearbox to your motor shaft and power transmission system.
- Maintenance and availability: Consider brands with clear specifications and readily sourced spare parts or compatibility with standard components.
- Application context: For robotics, imaging rigs, or small automation tasks, prioritize compact footprint, noise, and thermal performance appropriate to the environment.
- Budget and availability: Balance cost against necessary features. Small right-angle gearboxes often offer a good mix of performance and affordability for hobbyists.
In sum, these small right-angle gearboxes provide compact, efficient ways to reorient drive shafts without sacrificing torque or control. When selecting, prioritize shaft size, gear module, and mounting options to ensure reliable performance in your specific DIY or robotic project. Always align the gearbox with your motor and drive system to optimize efficiency and lifespan.
