Custom Right Angle Gearboxes: Define the Transmission Requirements

A right angle gearbox changes the direction of a drive through a defined input and output arrangement. HKAA reviews custom gearbox projects against the required shaft layout, ratio, operating conditions and manufacturing scope. Supply the assembly drawing and performance requirements with your RFQ.

Operating Data for Quotation Review

• Speed and ratio: identify input speed, required ratio and output speed.
• Torque and duty: state the required output torque, duty cycle and any starting, reversing or intermittent load conditions.
• Motion requirements: define backlash or positioning requirements and how they should be measured.
• Installation: provide mounting orientation, available space and the operating environment.

A general request for high torque or low backlash is not a complete acceptance specification. Include numerical requirements and test conditions where they determine suitability.

Shaft and Housing Interfaces

Specify shaft diameters, extensions, keyways, threads and connection details, together with the mounting-hole pattern and locating faces. Include the mating drive and driven-component information where needed to explain the interfaces. Identify the datum references that control assembly alignment.

Our custom shaft machining information covers related drawing requirements. Shaft material and processing must be specified for the individual gearbox design.

Component Supply or Complete Assembly

State whether the RFQ covers machined housings, shafts and other individual parts, or a complete assembled gearbox. Define the scope for purchased components, lubrication, seals and assembly. If you provide an existing design, include the controlled drawings and relevant parts list.

Related machining processes include CNC milling for housing and mounting features, and CNC turning for cylindrical features. Manufacturing scope is confirmed during project review.

Inspection and Functional Acceptance

Define dimensional inspection separately from complete-assembly testing. State any required checks for rotation, backlash, noise, temperature or load, including the method and acceptance criteria. A product photograph does not establish a rating or a test result.

Include material records, inspection reports, marking and packing requirements with the RFQ so the quotation can cover the requested delivery scope.

Right Angle Gearbox RFQ Checklist

• Assembly layout, drawings and available envelope.
• Ratio, speed, torque, duty cycle and motion requirements.
• Shaft interfaces, mounting dimensions and installation orientation.
• Component or assembly scope, materials and finishing.
• Quantity, test criteria and requested delivery date.

Frequently Asked Questions

Is the gear ratio enough to select a gearbox?

No. Speed, torque, duty, mounting orientation and interfaces must also be reviewed against the intended installation.

Can the quotation cover only the machined parts?

Identify the parts and drawings required, and state which purchased components, assembly work and tests are outside that request.

How should backlash be specified?

Provide the required limit and the measurement conditions or reference specification. This allows the acceptance requirement to be reviewed consistently.
