Product Description Customized Large Heavy Diameter Forged Steel Auto Transmission Propulsion Shaft Drive ShaftProduct DescriptionThis heavy-duty marine propulsion/crankshaft is forged from 38CrNi3MoVA steel, inspected via ultrasonic testing full-dimension CMM, compliant with DNV/ABS class rules. Induction hardened (HRC 52-58) for wear resistance, it suits icebreakers, container ships, and oil tankers, withstanding up to 200-ton thrust loads.LengthRange: >1mWeightRange: >100kg/ Single PieceShaft shapeEccentric Shaft MaterialForging 38CrNi3MoVA or CustomizedHeat TreatmentNormalizing, Tempering, Induction Harden, etcSand BlastingNullTestingUT\MTTrademarkTOTEM/OEMApplicationStone Crusher, Grate Cooler etcTransport PackageExport package (steel frame, wooden box, etc.)OriginChinaHS Code8483409000Working Principle&ApplicationWorking PrincipleThe propulsion shaft operates as the mechanical linkage between the ship's main engine and the propeller. During operation, rotational energy is transmitted through the shaft, which must withstand torsional stress, bending loads, and axial thrust. High precision and durability of the shaft are essential to ensure smooth power transmission and long-term reliability. ApplicationPropulsion Systems: Container ship/oil tanker propeller shaftsPower Generation: Cruise ship turbine generator shaftsSpecial Vessels: Icebreaker reinforced crankshaftsNaval Equipment: Destroyer transmission shafts Key Features Key Functions·Power Transmission - Delivers torque and rotational force from the engine to the propeller.·Structural Support - Supported by bearings to maintain alignment and reduce vibration.·Sealing & Protection - Uses sealing mechanisms to prevent seawater from entering the hull. Special Requirements in Icebreakers·High-Strength Materials - Resistant to ice impacts and extreme cold.·Shock Absorption - Designed to handle sudden impacts when the propeller strikes ice.·Redundancy - Some icebreakers use multiple shafts for backup propulsion.·Low-Temperature Adaptability - Lubrication and seals must function in freezing conditions. Machining Processes1. Material SelectionHigh-strength alloy steel (e.g., 42CrMo, 38CrNi3MoVA) or stainless steel.2. ForgingDie-forging under hydraulic press to eliminate internal voids.·Upsetting is a process of applying axial compression to a workpiece, reducing its height and increasing its cross-sectional area, thereby improving its transverse mechanical properties.·Stretching is a process of successively feeding and applying compression to a workpiece along its axis, increasing its length and reducing its cross-sectional area.3. Rough TurningRough Turning the blank. Shaping the future with precision.4. Heat Treatment Heat Treatment optimizing the microstructure for superior mechanical properties.5. QuenchingQuenching for extreme hardness and unmatched wear resistance.6. Finish TurningFinish Turning to micron-level accuracy. Defining final dimensions.7.Dynamic balancing test·Reverse Run-out Test bypassing machining distortion for true geometric accuracy. Tolerance:0.01mm.·Surface Roughness Measurement ensuring flawless finish for lasting performance. ·Classification Society Certification(CCS) meeting global standards for ultimate reliability.Packaging & ShippingEach propulsion shaft is meticulously prepared for international shipping. The standard packaging consists of:?Robust Wooden Crates: Custom-built to fit the shaft dimensions exactly, providing maximum structural support and impact resistance.?VCI Anti-Rust Film: The shaft is first wrapped in Volatile Corrosion Inhibitor (VCI) film. This material releases protective vapors that prevent rust and corrosion during transit and storage.?Steel Strapping: The sealed wooden crate is securely reinforced with heavy-duty steel straps to prevent any movement or damage during handling.?Additional Protection for Shipping:?Foam Spacers & Edge Guards: All sharp edges and critical surfaces (like bearing journals) are protected with high-density foam spacers and edge guards to prevent abrasion, scratches, or impact damage.?Weatherproofing: The packaging is designed to be weather-resistant, protecting the contents from moisture and environmental elements.?Marking & Labeling: Each package is clearly marked with handling instructions and product identification details for easy inventory management.HOT SALE PRODUCTS About TOTEMIn order to avoid the finish products rusted and damaged during the transportation ,we will design the right packing according to the shape,size and usage of the products.Shanghai Totem Machinery Co.,LtdFacebook: Shanghai TotemFAQWhat's TOTEM product processing progress?Drawing CHECK, Make Forging Mold, Forging Mold Quality Inspection Check, Machine Processing, Check Size\Hardness\Surface Finish and other technical parameters on drawing.
