TQG Servo Motor Planetary Gear Reducers PAW070A-CR Reducer 90 Degree Servo Gearbox Reductor Hollow Shaft with Keyway

Product Description

Product Overview
PAW-CR Product Overview 1
PAW-CR Product Overview 2
PAW-CR is a double hollow shaft clamping spiral bevel gearbox with keyway. Such right angle planetary gearbox is suitable for the application that require axis to go through the hollow shaft. The clamping and keyway design can effectively prevent shaft transmission from slipping when in the large load motion control.
PAW-2C-K right angle 90 degree gearbox is attached with input flange offering an easy mount with motor. The spiral bevel gear and spur gear planetary unit feature the 90 degree servo gearbox a compact structure. The integrated stainless steel body and optimized design ensures PAW-CR right angle gearbox with high precision, high torque and high rigidity, therefore, rotating smoothly with low noise and generate low heat.

Frequently Asked Questions
What are the available backlash levels for the PAW-CR series right angle gearbox?
The PAW-CR series offers three types of backlash configurations to meet different precision requirements: Standard backlash (10 to 15 arcmin), Precision backlash B2 (5 to 8 arcmin), and Precision backlash B1 (3 to 5 arcmin).
In what applications are these 90-degree planetary gearboxes typically used?
These gearboxes are widely used in automatic machinery and heavy load motion systems, including printers, belt conveyors, gantry robots, automatic packing sealing machines, vertical/horizontal pillow packing machines, dispenser robots, and loader robots.
What are the benefits of the double hollow shaft clamping and keyway design?
The clamping and keyway layout is optimized for applications where the axis must pass through the hollow shaft. This robust structure effectively prevents shaft slippage during high-torque and heavy-load motion operations.
What ratio options does the PAW-2C-K gearbox offer?
It supports a wide selection of transmission ratios. Single-stage options include 3, 4, 5, 6, 7, and 10. Two-stage options range from 12 up to 100, including ratios like 15, 16, 20, 25, 28, 30, 35, 40, 50, 60, and 70.
What is the torque capability and weight range of these gearboxes?
The series handles a nominal torque range between 10Nm and 1200Nm (technical model range is 30Nm to 1200Nm). The overall product weight varies from 2.9 kg for smaller configurations up to 63.5 kg for heavy-duty setups.
