Precision-Engineered Specifications: A Deep Dive into Performance and Durability
Every dimension and specification of the B1310 Series Companion Flange is meticulously engineered for optimal performance, structural integrity, and long-term reliability, reflecting superior design and manufacturing quality.
Bolt Circle Diameter (BCD): 3.125 inches (3-1/8") and 4-Bolt Hole Pattern
The 3.125-inch (3-1/8") Bolt Circle Diameter with a 4-bolt pattern ensures secure coupling and robust load distribution in torque transfer applications. This precise BCD optimally positions fastening bolts, evenly distributing shear forces and bending moments. The symmetrical 4-bolt arrangement provides stability, minimizing eccentric loading and premature wear. Consistency facilitates universal compatibility within the B1310 series, simplifying procurement. The bolted connection prevents relative motion, maintaining rotational stability and efficient power transfer.
Bolt Hole Diameter: 0.375 inches
The precisely machined 0.375-inch bolt hole diameter is crucial for optimal fit with standard fasteners. Minimal clearance resists shear loads and prevents fretting corrosion. Excessive clearance leads to stress concentrations and bolt fatigue. Tight tolerances ensure clamping force translates into a rigid, non-slip connection, enhancing drive shaft assembly durability and aiding repeatable alignment during installation.
Bore Diameter/Width: 1.250 inches and Round Bore Type
The 1.250-inch round bore defines the primary interface with the drive shaft, critical for a concentric and balanced connection. A precisely machined round bore ensures the shaft is centered, minimizing runout and dynamic imbalance. Deviations introduce vibrations and accelerate bearing wear. The round bore, with the keyway, forms a positive mechanical lock, directly transferring rotational torque. This 1.250-inch size ensures compatibility with a broad range of industrial and heavy-duty auxiliary shafts.
Key Width: 0.313 inches
The 0.313-inch key width corresponds to a precise keyway within the bore, designed for a standard key. This mechanical feature transmits torque from shaft to flange, preventing rotational slip. Accurate dimensioning ensures a snug fit, maximizing surface contact and distributing stress efficiently. The surrounding material withstands significant shear stresses, reliably transmitting torque loads without deformation, even under shock, guaranteeing a positive drive connection.
Flange Diameter: 3.875 inches and Flange Thickness: 0.375 inches
The 3.875-inch flange diameter and 0.375-inch thickness are fundamental to the component’s structural integrity and load-bearing capacity. The diameter provides substantial surface area for a stable, rigid bolted connection, resisting bending and twisting forces. The thickness withstands bolt clamping forces and transmitted torsional/bending stresses, preventing deformation and maintaining alignment. These robust dimensions manage high-torque loads and absorb dynamic stresses, extending the drive system's operational life.
Hub Diameter: 2.440 inches
The 2.440-inch hub diameter encompasses the bore, extending axially from the main flange face, providing critical material mass around high-stress areas. A generous hub enhances overall strength and rigidity, particularly at the shaft interface. It distributes forces from the shaft and key, mitigating localized stress peaks. The robust hub also aids dynamic balance, minimizing vibrations and ensuring smooth operation, especially at higher speeds. This dimension indicates the component's ability to withstand torsional and bending stresses for reliable performance.
Overall Thickness: 2.00 inches
The 2.00-inch overall thickness, or axial length, defines the component’s total dimension. Crucial for system integration, it ensures fit within machinery's space envelope. Beyond spatial considerations, this length contributes to structural stability and dynamic characteristics. A well-proportioned axial length, coupled with the hub diameter, resists bending moments and maintains concentricity under dynamic loading. It influences mass distribution for dynamic balancing, minimizing vibrations, and ensuring smooth power transmission. This dimension reflects balanced mechanical strength and system compatibility.
Material Science and Advanced Manufacturing for Unyielding Reliability
The B1310 Series Companion Flange utilizes high-grade alloy steels for superior strength, fatigue resistance, and toughness, with stringent metallurgical analysis. Precision forging aligns the steel's grain structure, yielding exceptional strength against impact and torsional stresses. Advanced heat treatment processes like quenching and tempering enhance mechanical properties, optimizing hardness, wear resistance, and ductility for severe operational demands and extended service life. Precision CNC machining achieves critical dimensions and surface finishes for the bore, keyway, bolt holes, and flange faces, crucial for proper fit and efficient power transfer. Surface treatments, such as black oxide or phosphating, provide enhanced corrosion resistance, ensuring reliable performance in harsh environments. This meticulous attention guarantees consistent, high-performance reliability.
