German Browning coupling Browning model Browning price

Browning coupling is a torsionally rigid coupling with zero backlash, even under load. Even when misalignment generates load, the rigid coupling still transmits torque rigidly. It features light weight, ultra-low inertia, and high sensitivity. It is maintenance-free, with excellent oil resistance and corrosion resistance. Materials include aluminum alloy and stainless steel. Set screw, clamp, and split types are available. Models with different bore sizes at each end are also in stock.

Browning coupling introduction

Any misalignment in the system will lead to premature damage to the shaft, bearings, or coupling; this means it cannot be used in high-speed environments because it cannot compensate for relative shaft displacement caused by high temperatures generated during high-speed operation. Of course, if relative displacement can be successfully controlled, rigid couplings can perform excellently in servo system applications. In particular, small-sized rigid couplings offer superior performance with light weight, ultra-low inertia, and high sensitivity. In practical applications, rigid couplings have the advantages of being maintenance-free, highly oil-resistant, and corrosion-resistant. Although rigid couplings were previously not favored for use in servo drives, due to their high torque capacity, rigidity, and zero-backlash performance, small-sized aluminum alloy rigid couplings are increasingly being used in motion control fields.

Browning coupling classification

Rigid couplings are divided into flange couplings, radial key flange couplings, sleeve couplings, split-shell couplings, and parallel shaft couplings. Flange coupling: A coupling that connects two shafts by bolting the flanges of two half-couplings together. Radial key flange coupling: A coupling that connects two half-couplings using a radial key and standard bolts. Sleeve coupling: A coupling that connects two shafts using a common sleeve. Split-shell coupling: A coupling that connects two shafts by clamping two axially split shells. Parallel shaft coupling: A coupling that connects two parallel shafts using an intermediate disc and pin shafts.

Browning coupling mechanical properties

The heating temperature for rigid couplings is typically 560~600℃, with a hardness requirement of HRC22~34. Since the purpose of quenching and tempering is to achieve comprehensive mechanical properties, the hardness range is relatively wide. However, if the drawing specifies hardness requirements, the tempering temperature must be adjusted according to the drawing to ensure the required hardness. For example, some shaft parts require high strength and thus high hardness; while some gears and shaft parts with keyways require lower hardness because milling and broaching operations are performed after quenching and tempering. The tempering holding time depends on the hardness requirements and workpiece size. We believe that the hardness after tempering depends on the tempering temperature and has little relation to the tempering time, but thorough tempering is essential. Generally, the tempering holding time for workpieces is over one hour. Cr can increase the hardenability of rigid couplings, improve steel strength and tempering stability, and provide excellent mechanical properties. For large cross-section or important quenched and tempered workpieces, Cr steel should be used. However, Cr steel exhibits second-type temper brittleness. Looking at international development trends, new-generation CNC machine tools are moving towards ultra-high speeds to improve production efficiency, using new functional components (such as electric spindles and linear motors) to achieve ultra-high-speed machining. The electric spindles and linear motors required for rigid couplings connect the motor directly to the main shaft via expansion tightening sleeves, eliminating intermediate components such as gearboxes to achieve ultra-high speeds. A single CNC machine tool requires at least five to six sets of couplings, and up to fifty to sixty sets. This indicates a very large market. The German Lingsi rigid coupling industry is becoming increasingly popular. Coupled with factors such as corporate management, we will analyze what trends the coupling industry will present in the near future.
