We also offer solutions ranging from precision-cast large equipment bases to ±0.005mm precision-ground fixtures, quick-change industrial control spare parts (FA parts), and repair parts with ±0.01mm precision milling and turning. These solutions enable your production line to achieve improved accuracy and doubled efficiency without interrupting production.
what is Right Angle Gearbox with Hollow Shaft?
The right-angle hollow shaft gearbox is a precision transmission device that integrates 90° right-angle power steering with a center hollow shaft for cable threading. The motor is mounted perpendicularly to the turntable at a 90-degree angle, utilizing a multi-stage gear transmission to increase output torque. The hollow shaft structure also accommodates cables and air pipes. Its core value lies in addressing the need for high-torque precision transmission in space-constrained environments. Compared to traditional direct-connect gearboxes, it reduces installation height by over 40% and offers a repeatable positioning accuracy of ±30 arc seconds. It is widely used in automation equipment, robotic joints, and other applications where both space and precision are critical.

product Important Characteristics and Advantageous Effects
Applications with limited space will find right-angle gearboxes with hollow shafts often compact, which is advantageous.
Different input/output needs and varied mounting options made possible by the hollow shaft help to meet both.
Capable of transmitting great torque, they are fit for heavy-duty uses.
Designed for great efficiency with little backlash, particularly in applications requiring exact motion, this helps notably.
Common in robotics, packaging, conveyors, and material handling systems because of their adaptability and accuracy is versatility.
FAQ
Q: Is there a difference between right-angle hollow shaft gearboxes and 90-degree hollow shaft gearboxes?
A: The key differences lie in their transmission structure and application scenarios:
Right-angle hollow shaft gearboxes utilize a multi-stage gear transmission, focusing on "high torque and compact size" (e.g., 1800 N·m of torque can be integrated into a 300 mm volume), making them suitable for heavy loads.
90-degree hollow shaft gearboxes typically utilize a worm gear transmission, focusing on "high precision and low noise," but offering lower torque (typically ≤1000 N·m).
Selection Recommendation: Choose a right-angle hollow shaft gearbox for heavy-duty applications (such as automotive welding), and a 90-degree hollow shaft gearbox for precision and light loads (such as electronic testing).
Q: How can I ensure the coaxiality of the motor and gearbox during installation?
A: Coaxiality is critical. Follow these steps:
Use a dial indicator to measure the radial runout between the motor flange and the gearbox input shaft. The error must be ≤0.02mm.
Use the "locating pin + bolt pretightening" method: First, use the locating pin for initial positioning, then pretighten the bolts diagonally (torque 50-80 N·m). Finally, tighten with a torque wrench to the indicated value.
Q: What should I do if my gearbox leaks oil after long-term use?
A: Oil leakage is often caused by aging seals, and the solution is simple:
Location: Commonly found at the input or output shaft seals (90% of the time, this is caused by worn shaft seals).
Replacement steps: Turn off the motor → Remove the motor flange → Remove the old oil seal using a special tool → Install a new one.
Preventative measures: Check the oil level every six months (refill with special gear oil when it's below 1/3 of the sight glass) to prevent excessive oil levels from causing pressure leaks.
Q: Can the gearbox be used outdoors or in humid environments? What protective measures are required?
A: For outdoor use, customized protection solutions are required:
Humid/dusty environments: Upgrade to IP65 protection (double-lip oil seal on the shaft end + housing seal), and fill the gearbox with water-resistant grease.
For outdoor use exposed to rain: Install a rain cover (we can customize a stainless steel cover), and replace the air vent with a waterproof vent valve.
For salt spray environments (such as at the seaside): Galvanize the housing surface and spray paint, and add a rust inhibitor to the gearbox.
