Overhung Load Maven Support

Overhung Load Maven is a Mac engineering application for pulley, shaft and drive-assembly loads, with interactive 3D geometry and dimensioned drawings.

Contact support

Email support@mavensoftware.ai. Include the app version, macOS version, the steps that led to the issue and the expected result. Attach a .ohlmaven project or screenshot only if you choose to share it.

Requirements

The Mac app requires macOS 15 or later and an Apple silicon Mac. Engineering calculations run locally without a Maven account.

Set up an assembly

Choose End A, End B or both in Drives. Set each motor’s leading or lagging mounting, torque share and 50 Hz or 60 Hz motor data. In Geometry and Masses, select the end you want to edit. Cases contains whole-pulley belt tensions and travel.

Drag to orbit the 3D assembly, Shift-drag to pan and scroll to zoom. Drawing provides a dimensioned plan and swing-base elevations showing the shaft, frame hinge and foundation pin. Linkage and pinned-pedestal supports can be selected independently for each drive.

Read the results

Results reports five operating cases, bearing reactions and each end’s drive-base reactions. Belt arrows show the selected case’s tension and travel. Leading or lagging mounting refers to the saved reference upper-span travel. The x axis runs from Bearing A toward Bearing B, y is upward, and positive z is away from the belt. Bearing loads are the forces from the shaft on the housings.

The model assumes two simple bearing supports, rigid drive frames and vertical support reactions. Linkage dimensions describe the rendered pin geometry; changing their heights does not change the vertical static load solution. Inclined link forces, shaft stress, bearing life, frame strength, vibration and dynamic transients require separate engineering checks.

Save and open projects

Use File → Save to save a .ohlmaven document. Use File → Open to reopen it. Store documents in a folder you control. Earlier saved angle conventions are migrated when their schema requires it, and missing linkage settings receive compatible defaults.

Payments and privacy

Bearing and drive calculations require an annual subscription. Geometry editing, 3D inspection, drawing dimensions and saving documents remain available without a subscription. The US price is $10 per year, with a two-week free trial for eligible new subscribers. The App Store shows your local price and confirms trial eligibility. Subscriptions renew annually until canceled; cancel at least 24 hours before the trial or current period ends in Apple’s subscription settings.

Open Subscription in the app to purchase or start an eligible trial, restore an existing purchase, refresh StoreKit status or manage your subscription. If the product cannot load, check your App Store connection and try Refresh store. Apple handles payments. For billing help, visit Apple billing support.

Your engineering inputs and documents stay on your Mac unless you choose to share them. Read the Privacy Policy and Terms of Use.
