    The use of bolts, short pipe connection without the amount of elasticity for the rigid coupling, otherwise the elastic coupling. Rigid coupling that is high hardness in the course of the operation will not occur in the deformation of the coupling, rigid coupling is not allowed to have the phenomenon of misalignment. Elastic coupling refers to the higher flexibility, in the course of the operation to allow the occurrence of deformation of the coupling, connecting the elastic coupling on both sides of the shaft allows a certain amount of misalignment phenomenon.

Rigid couplings are characterized by light weight, ultra-low inertia and high sensitivity; maintenance-free, super-oil and corrosion resistance. Rigid coupling is divided into flange coupling, radial key flange coupling, sleeve coupling, clamping shell coupling and parallel shaft coupling

    Botou Yusheng Coupling Co., Ltd. reminds customers of the flange coupling is the use of bolts to connect the flange half of the coupling to achieve the coupling of the two shaft coupling

    Radial key flange coupling: Coupling with two-half coupling with radial and common bolts

Sleeve Coupling: Couplings of two axes are used in some way using a common sleeve

A coupling that is clamped in two ways to achieve a two-axis coupling by means of two axially divided clips.

Parallel shaft coupling: A coupling that utilizes an intermediate disc through a pin to achieve two parallel shaft connections

Rigid coupling heating temperature is usually 560 ~ 600 ℃, hardness requirements for the HRC22 ~ 34. Because the purpose of quenching and tempering is to get comprehensive mechanical properties, so the hardness range is wide. But the drawings have hardness requirements, it is necessary to adjust the tempered temperature according to the drawings to ensure the hardness. If some shaft parts require high strength, hardness requirements on the high; and some gears, with keyway shaft parts, due to tempering but also after milling, plug processing, hardness requirements on the lower.

On the tempering holding time, depending on the hardness requirements and the size of the workpiece, we believe that the hardness after tempering depends on the tempering temperature, and the tempering time is not, but must be back through, the general workpiece tempering holding time is always More than an hour.

Cr can increase the hardenability of steel coupling, improve the strength of steel and tempering stability, with excellent mechanical properties. Section size large or important quenched and tempered workpiece, should be used Cr steel. But Cr steel has a second type of temper brittleness. From the foreign development trend, a new generation of CNC machine tools to improve production efficiency, towards the ultra-high-speed direction, the use of new functional components (electric spindle, linear motor, etc.) to achieve high-speed processing.
