40 HP Right Angle Bevel Gearbox with Crosshole & 1″ Keyed Shaft
Generic’s 40 HP right angle bevel gearbox offers a robust 1:1 ratio with a 1″ keyed shaft. The unit features a precise bolt pattern, measuring 4-1/4″ square with 3/8″ tapped holes, enabling straightforward mounting in tight spaces. The OE part number variant (19455-SR-KW-KW-GR) helps with compatibility in legacy installations. Applications include high-torque tasks where a direct 90-degree drive is needed, maintaining alignment while minimizing footprint. Consider mounting access and shaft coupling when integrating with existing driven components.
Holdia 40 HP Right Angle Bevel Gearbox With Three 1″ Shafts
Holdia’s 40 HP gearbox supplies three 1″ keyed shafts with a 1:1 ratio, offering flexibility for multiple output configurations. The body is drilled and tapped on a 4-1/4″ square pattern with 3/8″ holes, matching common mounting standards. Notably, the gearbox can be configured to produce CW/CW/CCW output when the input rotates clockwise, enabling synchronized or divergent drive layouts. This versatility is beneficial in conveyor segments and multi-output drives where synchronized rotation is important.
uxcell Gear Box 90 Degree Right Angle Bevel Gearbox
uxcell presents a lightweight 1:1 bevel gearbox with a 10mm input/output shaft. The aluminum frame aids portability and durability, while the 45# steel shaft material ensures strength and corrosion resistance for reliable long-term service. It is designed for straightforward power transmission with a focus on smooth rotation and easy mounting in DIY projects and compact machines. Its modular design helps engineers and hobbyists test angular drives with minimal tooling.
1:1 Right Angle Tapered Bevel Gearbox (tpengine)
tpengine’s 1:1 tapered bevel gearbox integrates a 20-tooth bevel gear set with a 15mm shaft, offering a compact solution for simple mechanical applications. Its aluminum construction provides lightness and adequate strength for small to mid-scale drives. The device supports standard CNC or DIY setups where a right-angle interface is required, and it notes compatibility with common mechanical assemblies through its modest footprint and straightforward mounting.
ZORZA 1Pcs Gear Box 1:1 Right Angle Bevel Gearbox
ZORZA’s 1:1 right angle bevel gearbox presents a compact option with a 10mm inner hole and 27mm outer diameter. It includes two M5 screw holes for secure mounting and is suitable for straightforward DIY projects and simple mechanical drives. Its small footprint makes it a practical choice when space constraints exist, while maintaining reliable torque transfer at a 1:1 ratio.
PGFUN 1:1 Right Angle Tapered Bevel Gearbox
PGFUN offers a 1:1 right-angle tapered bevel gearbox with an 8mm shaft and an 8 mm input/output arrangement. The unit features a built-in 1 module 20 teeth bevel gear pair and supports a maximum torque around 5 N·m with a maximum speed near 1500 rpm. It is suitable for simple DIY mechanical applications and motor drive experiments, including belt or coupling-based drive implementations. The compact build is ideal for small CNC or robotic projects where straightforward angular transmission is desired.
PGFUN 1:1 Right Angle Tapered Bevel Gearbox (15mm Shaft)
This variant from PGFUN features a 1:1 right-angle tapered bevel gearbox with a 15mm shaft, designed for simple CNC and mechanical DIY tasks. It offers a 1.5 module gear set and a 20-tooth bevel configuration, with a stated maximum axis loading and torque similar to other compact units. It is suitable for projects requiring a longer shaft than the 8 mm variant, expanding the range of potential mounting options and drive layouts.
uxcell 90 Degree Right Angle Bevel Gearbox (Double Output)
uxcell offers a 90-degree bevel gearbox with a 1:1 ratio and a reversible double output shaft design. The aluminum frame keeps weight down while delivering durability. The 8mm shaft configuration on a single input with forward and reverse dual outputs provides flexibility for mechanisms requiring mirrored drive or bi-directional operation. This setup is well-suited for compact automation ensembles and simple robotic actuation where space is at a premium.
Buying Guide: Key Purchase Considerations And Comparisons
When selecting a right angle gearbox, consider the following factors to ensure a good fit for your application:
- Torque And Load: Compare maximum torque ratings and shaft dimensions. For high-torque tasks, prioritize units with robust housings and larger shafts.
- Ratio And Output Configuration: Most options here are 1:1. If you need multiple outputs (CW/CW/CCW or dual outputs), verify shaft arrangements and mounting compatibility.
- Mounting Pattern And Footprint: Check bolt patterns (e.g., square patterns with tapped holes) and overall dimensions to fit existing mounts and enclosures.
- Material And Durability: Aluminum frames give lightness; steel components can provide extra strength for demanding environments. Consider corrosion resistance for outdoor or wet settings.
- Input/Output Shaft Size: Confirm shaft diameter and keying; ensure compatibility with existing couplings, belts, or pulleys.
- Maintenance And Serviceability: Look for accessible bolts, seals, and straightforward disassembly for maintenance or replacement.
- Compatibility With Existing Equipment: If you are replacing an OE unit, verify part numbers (like 19455-Series) and bolt patterns to avoid misfits.
- Installation Flexibility: Some units support CW/CW/CCW, which can simplify complex drive trains. Others emphasize single-direction simplicity for reliability.
In practice, the best choice depends on your specific application: whether you need a compact footprint for a tight robotic arm, a high-torque drive for a conveyor segment, or a versatile multi-output solution for a modular machine. Compare mounting options, shaft sizes, and torque ratings carefully, and consider whether aluminum or steel construction better suits your operating environment. For hobbyist projects, lighter, modular units with standard shaft sizes often offer the best balance of cost, ease of use, and upgrade potential.
