Product Name: HDT-Super Series – Heavy-Duty Customizable Planetary / Parallel Reducer
I. Product Introduction
The HDT-Super Series is a heavy-duty transmission solution developed for extreme operating conditions and special spatial constraints. Unlike standard modular products, this series adopts modular reverse design and a flexible manufacturing system, breaking the traditional limitation of "selecting a machine based on a standard model."
The series can be configured as either coaxial planetary (high power density) or parallel shaft (large center distance, offset input). With case-carburized and ground gear technology and high-clearance heavy-duty bearings, it delivers exceptional torque capacity while maintaining high precision—something standard components cannot achieve. Our core manufacturing strength lies in our non-standard production capability: no rigid assembly lines, dedicated to "small volume, large size, complex condition" projects. All non-standard gears, splined shafts, and offset housings are manufactured and finished in-house. Designed for heavy-duty, low-speed applications in metallurgy, shipbuilding, new energy, large-span material handling, and mining.
II. Key Application Areas
New Energy (Lithium Battery / Solar) : Large coating machines, winder wall drives, high-torque synchronous stretching stations.
Metallurgy & Non-Ferrous Metals : Large rolling mill screw-down devices, furnace charging manipulator slewing mechanisms, cooling tower long-shaft drives.
Port & Marine : Large ship unloader bucket wheel drives, quayside container crane luffing mechanisms, marine deck cranes.
Engineering & Mining : Large vibrating feeders, screw conveyors, bucket elevators, and auxiliary drives for shield tunneling machines.
Non-Standard Automation Lines : Large-span gantry robot rail travel drives, heavy-duty AGV lifting and rotating mechanisms.
III. Functional Features
Dual-Compatible Architecture : By changing flanges and end covers, the same housing can achieve planetary output (compact structure) or parallel output (suitable for shaft extensions or chain drives), reducing on-site modification costs.
Full-Spectrum Non-Standard Customization (Factory Core Strength):
| Customization Dimension | Available Non-Standard Options |
|---|---|
| Structural Topology | Coaxial planetary / parallel offset / right-angle (bevel gear) / double shaft extension / hollow through-shaft / splined hollow shaft |
| Shaft & Bore | Extra-large hollow shaft (max bore 500mm+), splined shaft, extended shaft, keyed/flatted shaft, non-standard spigot fits |
| Mounting Orientation | Any-angle inclined mounting, vertical inverted mounting, floating suspension mounting, non-standard foot positions |
| Performance Specifications | Special ratios (e.g., 23.7, 71.5), ultra-low backlash (<3 arcmin), extra-high radial load capacity (>500 kN) |
| Environmental Adaptation | High-temperature resistance (oil cooling + insulation layer), dust resistance (positive pressure seal + labyrinth protection), corrosion resistance (special coating) |
| Power Interface | Direct connection for IEC standard motors, servo motors, hydraulic motors, pneumatic motors, plus options for overload clutch interfaces or encoder interfaces |
Multi-Stage Sealing Protection : Standard dual fluororubber oil seals + labyrinth return groove. High-pressure shaft seals available for dust, moisture, and cyclic shock loads.
Maintenance-Friendly : Inspection windows, drain valves, and breather caps can be positioned according to site safety procedures to avoid maintenance dead zones.
IV. Core Advantages
Deep Non-Standard Capability : We don't say "can't do it." Non-standard center distances, non-standard ratios, non-standard flanges, shafts machined from sketches—all are achievable. Mixed orders with both planetary and parallel configurations are accepted, with separate drawings and unified production scheduling.
Breakthrough Response Speed : Parametric design of core components (ring gears, sun gears) reduces lead time by up to 30% compared to competitors for non-standard requirements. Future replacement parts can be ordered using only the project number from the nameplate—no need to return the entire unit.
Rigidity & Impact Resistance : Large housings made of GGG-60 ductile iron or welded steel, with stress-relief annealing. Impact resistance is twice that of ordinary castings, suitable for frequent forward/reverse operation under harsh conditions.
High Precision & Long Life : Gears achieve ISO 5–6精度, surface hardness HRC 58–62. Theoretical design life up to 100,000 hours, with maintenance intervals extended to 2–3 years.
Superior Temperature Control : Large oil bath lubrication plus optional forced cooling fans keep temperature rise below 40°C under heavy loads, ensuring continuous operation.
Process Transparency : Technical reviews available before non-standard dimension confirmation. Inspection reports for key processes (gear grinding, housing finishing) provided, with customer acceptance points available.
V. Customization Service Process (Four Steps to Factory Technical Support)
| Step | Description |
|---|---|
| ① Requirement Submission | Provide original model (if any), installation space sketch, torque/speed data, and interface requirements |
| ② Solution Proposal | Engineers return a non-standard concept sketch and preliminary dimensions, confirming customizable items |
| ③ Drawing Confirmation | Detailed 2D general assembly drawing and 3D model of key non-standard components |
| ④ Production & Delivery | Machining → Assembly → Testing (simulated load according to non-standard conditions) → Shipment |
VI. Selection Parameters (Non-Standard Extensions Available)
