Hollow Shaft Planetary Gearbox: High Precision and High-Torque Solutions

Introduction to Hollow Shaft Gearbox

The hollow shaft gearbox offered by WLY enables you to power a machine shaft directly via a clamping set. This gearbox employs high-precision spiral gearing that has been tried and tested for its effectiveness in right-angled torque and acceleration transmission.

Efficiency in Installation

The machine shaft can be inserted directly into the gearbox's hollow shaft and linked with a mounting set for a force-fit connection. This straightforward method eliminates the need for additional aids such as intermediate flanges or . The WLY gearbox can be directly screwed onto the machine using the through holes in the output flange, making the installation process a breeze.

Maximizing Flexibility with Right Angle Gearbox

As an alternative, you can also choose the right-angle gearbox with a two-sided hollow shaft. This design allows you to route lines that were previously leading out from the machine shaft through the gearbox. This greatly increases your flexibility and allows you to take full advantage of the versatility provided by the servo gearboxes with hollow shafts.

Optimal Space Utilization

Thanks to its right-angled design, the hollow shaft gearbox allows you to maximize the use of limited installation space with a space-saving drive component. Additionally, these gearboxes come with lifetime lubrication, and their design allows them to be installed and used in any mounting position. This gives you complete freedom in the positioning of your drive and the design of the installation space.

Superior Torque with Cycloidal Speed Reducers

The WLY High Torque cycloidal speed reducers are designed to offer the same high precision as the standard series with a few notable advantages. An advanced cam follower design and built-in camshaft provide higher torque ratings (20-25%) and a large hollow shaft for passing wires.

Features of the Reducer

Reducer Features include:

  • 3 Frame Sizes
  • 10 Standard ratios from 25:1-225:1
  • Compound Reduction Cam
  • Compact, pancake design
  • Needle bearing cam followers
  • TRUE Zero Backlash
  • Integral capacity output bearing
  • Greased for life
  • Large Diameter hollow shaft

These devices are extremely efficient in commercial applications characterized by vibrations and continuous motion inversions. They are equipped with a hollow shaft sized for any type of shrink-disc, and a torque arm suitable for any application.

WLY: Your Trusted Provider of Hollow Shaft Planetary Gearboxes

At WLY, we pride ourselves on being a leading provider of hollow shaft planetary gearboxes. Our offerings are characterized by their high reduction ratios ranging from 3:1 to 50000:1 and rated torque from 0.5 Kg-m to 145000 Kg-m. These gearboxes can accommodate input power from 0.25 HP to 100 HP and are available in various input and output types.

Helical Geared Hollow Shaft Gearboxes

Our helical geared hollow shaft gearboxes are designed with a monoblock housing and can accommodate wide ratios and torque ranges. The reduction can be increased up to six stages, and the common IEC B5 or B14 motor flanges offer additional flexibility. These gearboxes are also equipped with long-life bearings and 58-62 HRc hardened and grinded gears for added durability.

WLY D-Series: Compact and Easy to Mount

The WLY D-Series is designed with compactness and ease of mounting in mind. These gearboxes are modular in design, and the output shaft and flange can be mounted to standard hollow-shaft gearboxes without modification. The input side of the hollow-shaft gearboxes also offers new mounting options.

Output Flange and Output Shaft Options

There are also servomotor-specific connection flanges, electromagnetic brake motors (24V/220V/380V), backstop application, 500-1024 pulse encoder applications, and an external fan cooling option for frequency inverter applications.
