01 / Gear types
Choose a starting direction.
Define the complete drive.
The gear type is one part of the specification. Confirm its actual catalogue ratio, mechanical and thermal ratings, lubrication and mounting for the project.
Helical-Bevel
Discuss the shaft arrangement, output direction, torque and mounting envelope for the intended drive.
Parallel Shaft Helical
Coordinate the available shaft spacing, motor interface and installation footprint for the travel or hoist drive.
Planetary
Review ratio, output torque, mounting space and the exact input/output arrangement for the proposed model.
Worm
Share operating speed, duty and thermal conditions. Holding behavior and backdrivability require model review.
02 / Selection guide
Operating data first.
Installation details alongside.
Use the existing drive data or describe the new motion. These four areas help make the first technical review productive.
Speed & transmission
Specify hook or travel speed, drum/wheel diameter, reeving and any external gearing. For slew, provide rotary speed and torque.
Torque & load cycle
Include starts per hour, acceleration time, operating cycle, load spectrum and actual motor/shaft data.
Shafts & mounting
Share shaft dimensions, key/spline details, foot/flange dimensions, output direction and the available installation space.
Oil & thermal review
Record ambient conditions, operating hours, lubrication arrangement, sealing needs and cooling constraints.
03 / Configure & plan
Build the gearbox enquiry.
Review the assumptions.
Record the operating data and package requests. The existing budget model is retained for comparison; direct drum/wheel kinematics are shown separately for a clearer technical discussion.
Your Gearbox Configuration
The sample values do not identify a selected gearbox. Hoist speed means hook speed; diameter means the driven drum or wheel. Supply rotary data separately for Slew / Other.

03 / Installation

04 / Supply request
Options, quantity & target timing
Options and IP ratings require model confirmation. Target timing is a request, not confirmed delivery. Backstop suitability and locking direction need review.
04 / Technical scope
Ratio, torque and mounting.
One coordinated specification.
These source ranges and option areas are discussion references. Confirm actual ratings, execution and available documents for the proposed catalogue model.
| Types | Helical-bevel, parallel shaft helical, planetary and worm. Exact model/series confirmed in the proposal. |
|---|---|
| Applications | Hoist drums, trolley drives (CT), long-travel (LT), slewing & auxiliary motions |
| Ratio Range | Original planning reference: approximately 5:1–300:1; up to 1000:1 with planetary arrangements. Actual catalogue availability requires confirmation. |
| Output Torque | Original planning reference: 200–120,000 N·m. Confirm the actual model rating and duty; the calculator does not select a rated unit. |
| Protection | Requested IP55–IP66; confirm the applicable protected assembly, sealing, breathers and heater requirements. |
| Lubrication | Mineral / synthetic oil bath or splash; forced lubrication for high speed/duty |
| Options | Backstop, torque limiter, inspection window, temperature sensor, paint systems |
| Docs & Tests | Request GA drawings, run-test scope, oil sample and QC report; confirm the agreed inspection and documentation scope. |
Source ranges are not a guarantee for every gear type or model. Confirm mechanical strength, thermal rating, lubrication, shaft loads and installation orientation separately.
05 / Drive details

Confirm the model, scope and inspection plan before manufacture and delivery.
Sizing
Load, speed, diameter, duty and environment.
Proposal
Review catalogue ratio, torque, interfaces and budget.
Fabrication
Confirm machining, assembly and run-in scope.
Testing
Agree the vibration/noise, oil and inspection checks.
Delivery
Confirm drawings, documentation and packing.
07 / Before you specify
Planning a gearbox
replacement or new build?
Actual operating data and interfaces guide the selected model.
Discuss My Drive Requirements ↗What information helps identify a replacement gearbox?
Send the gearbox and motor nameplates, input/output speeds, rotation direction, shaft and mounting dimensions, clear photos and actual operating duty. The replacement model and scope follow the technical review.
Why are direct kinematics and legacy budget figures different?
For hoisting, direct drum rpm uses hook speed multiplied by rope falls. Its ratio is motor rpm divided by drum rpm, without a clamp. The existing budget model omitted that falls multiplier and clamped output rpm/ratio. We retain those legacy figures only to preserve the original budget comparison; they do not define the final ratio or motor.
Does the displayed factor verify M4, M5 or M6 duty?
No. It is an illustrative factor from the original model, including its ED assumption. Final selection requires model-specific load, mechanical and thermal checks; it does not prove FEM, ISO or AGMA compliance.
Can I use Slew / Other for a rotary drive calculation?
That choice records the application, but the original budget branch uses a rolling-resistance travel proxy. It does not size a slew drive. Provide actual rotary speed, inertia, torque and external gearing for review.
Does a backstop replace a brake, or a heater address high ambient?
No. Verify the actual brake/holding function and backstop suitability, speed and locking direction. Oil heaters address low-temperature needs; high ambient requires separate oil, thermal-capacity and cooling review.
Is the budget per gearbox, and is the timeline confirmed?
The range is the original EXW equipment total for the entered quantity, including quantity discount and urgent-request assumptions. It is not a firm offer. Timing options are requested targets; price, scope and delivery require confirmation.
