Machine duty
Explain peak and continuous load, start/stop frequency, shock events, braking, direction changes, shaft support and inspection access. These inputs help the quotation reflect the actual machine rather than an industry label.
Application guidance
Spiral Bevel Gears for Heavy Lifting & Hoists
Lifting and hoist mechanisms place the emphasis on load spectrum, starts and stops, shock, braking events, support stiffness and inspection access. Nominal torque alone is not enough to describe the duty.
Where the spiral bevel pair sits in the system
Heavy-duty transmissions need a clear picture of how the load reaches the gear pair and how the shafts are supported. Bearing arrangement and housing stiffness matter because tooth contact depends on the position of the two members under load.
For maintenance replacements, add inspection history, visible damage and any measured changes in backlash. Damage patterns can help explain the service problem, but they should not be copied into the new geometry as if wear were part of the original design.
Operating conditions to put in the RFQ
Mating pair
Identify both members, tooth counts or ratio, hand and which component drives.
Assembly geometry
Show the shaft angle, mounting references, bearing positions and any controlled backlash.
Penerimaan
State the inspection or contact checks that matter to release the part for this machine.
Application review table
| Review area | What to provide | Why it matters |
|---|---|---|
| Motion / duty | Peak and continuous load, start/stop frequency, shock events, braking, direction changes, shaft support and inspection access | Separates steady power transmission from reversing, shock or position-sensitive duty. |
| Pasangan gear | Gear + pinion identity, ratio/tooth counts and hand | Prevents one component from being reviewed without its mating geometry. |
| Mounting | Shaft arrangement, bearing support, housing datums and target backlash | Connects the manufactured part to the position it will hold in the assembly. |
| Environment | Lubrication, temperature and contamination context | Supports practical material, finish and service review without inventing machine-level claims. |
| Inspection | Drawing tolerances, tooth finish and required records | Defines what the buyer will use to accept the ordered configuration. |
Resolve integration risk before production
A single “maximum torque” value can hide frequent starts, impact events or reversing load. Send the load spectrum and duty cycle when available, and identify whether the pair is exposed to overload or emergency events that the design must consider.
Heavy-duty or custom spiral bevel gear pairs are appropriate starting pages. Ground tooth finishing should be specified only when the drawing or performance requirement calls for that manufacturing route.
If a lifting or hoisting mechanism still has open geometry or duty inputs, mark those items for review. An explicit unknown is safer than filling the drawing with an assumed standard value.

Do I need to know the exact gear material before requesting a quote?
When the lifting or hoisting mechanism drawing controls material or heat treatment, include the exact requirement. If those choices remain open, describe the duty and leave material/process selection for review.
Can I send only a photo of the installed gear?
Photos of the lifting or hoisting mechanism help establish orientation and condition, but they do not define tooth geometry or mounting datums. Add the mating member, drawing data and measurements taken from controlled assembly references.
Should the RFQ include the complete machine drawing?
For the lifting or hoisting mechanism, send the assembly information that controls shaft relationship, mounting datums and interfaces. Unrelated machine details can be omitted when they have no effect on gear selection or inspection.
What quantity should I state for a prototype?
For the lifting or hoisting mechanism, separate prototype/sample quantity from expected repeat demand. This keeps tooling, inspection and production planning tied to the real purchasing stage.

Panduan pesanan & penghantaran
MOQ adalah fleksibel mengikut jenis produk, laluan pembuatan dan jumlah nilai pesanan. Projek baharu yang sesuai boleh meminta 1–5 sampel barang pada harga sampel. Model campuran boleh digabungkan apabila jumlah pesanan mencapai kira-kira USD 1,500. Pesanan 1–2 barang boleh disemak, walaupun kos seunit biasanya lebih tinggi.
Tempoh perancangan biasa ialah 10–25 hari bekerja untuk bahagian standard, 20–45 hari bekerja untuk komponen tersuai dan 45–120 hari bekerja untuk peralatan atau pemasangan jenis projek. EXW, FOB, CIF dan DAP biasanya disokong; FCA, CFR, CPT, CIP dan DDP boleh dibincangkan untuk penghantaran.
