German speck pumpen coupling, speck pumpen model, speck pumpen price

speck pumpen coupling is a torsionally rigid coupling with zero backlash even under load. Even when misalignment generates load, the rigid coupling transmits torque rigidly. Lightweight, ultra-low inertia, and high sensitivity. Maintenance-free, with excellent oil and corrosion resistance. Made of aluminum alloy and stainless steel. Available in set screw, clamping, and split types. Models with different bore sizes at both ends are also in stock.

speck pumpen coupling manufacturing process

Jaw couplings are machined by turning, milling, and broaching, followed by overall heat treatment to ensure sufficient mechanical strength. There is also a type of jaw hub on the market that is cast, allowing for mass production and eliminating machining loss. Therefore, the price is much lower than that of machined parts. However, the performance of castings is not very good. It is best not to use them in critical applications. Furthermore, the jaws of cast hubs are prone to tooth breakage (jaw detachment) under high speed or high load conditions. 1) Compact, zero-backlash, available with three different hardness elastomers; 2) Absorbs vibration, compensates for radial and angular misalignment; 3) Simple structure, easy maintenance and inspection; 4) Maintenance-free, oil-resistant, electrically insulating, operating temperature 20℃ to 60℃; 5) Jaw elastomers are available in four, six, eight, and ten jaws; 6) Fixing methods include set screw, clamping, and keyway fixation.

speck pumpen coupling application range

Jaw couplings are widely used in CNC machine tools, CNC lathes, machining centers, engraving machines, CNC milling machines, computerized milling machines, metallurgical machinery, mining machinery, petroleum machinery, chemical machinery, lifting machinery, transport machinery, light industry machinery, textile machinery, water pumps, fans, etc.

speck pumpen coupling installation and usage

1) Wipe the dust and dirt from the installation shaft surface clean, and apply a thin layer of machine oil or lubricant. 2) Clean the inner bore of the coupling and apply machine oil or lubricant. 3) Insert the coupling onto the installation shaft; if the bore fit is tight, avoid striking with an iron hammer or hard metal during installation. 4) After positioning, first tighten the screws gently in a diagonal pattern using a torque wrench (specified tightening torque 1/4). 5) Increase the force (to 1/2 of the specified tightening torque) and repeat step 4. 6) Tighten and fix according to the specified tightening torque. 7) Finally, tighten the fixing screws sequentially in a circumferential direction. 8) For disassembly, please perform only when the device is completely stopped; loosen the locking screws sequentially.
