JQ-160 JQ Type Clamping Coupling \u2013 160mm Split-Body Reactor Stirring Shaft Connection<\/h1>\n

The JQ-160 JQ type clamping coupling<\/strong> is a split-body rigid shaft connector engineered for reactor stirring shaft applications where the shaft is manufactured in two sections \u2014 either because the complete shaft length exceeds what can be handled as a single piece during installation, or because a vertical gearbox output shaft must be connected to the reactor agitator shaft with non-standard bore dimensions. At 340 mm outer diameter and 500 mm overall length, the JQ-160 is sized for 160 mm shaft connections with a nominal torque rating of 28000 N\u00b7m, covering the full operating torque range of industrial agitator drives at this shaft size.<\/p>\n

The JQ clamping coupling operates on the principle of split-body radial clamping: the coupling body is manufactured in two semi-cylindrical halves that wrap around the two shaft ends from the side and are drawn together by 26 clamping bolts. When the bolts are tightened to the specified torque, the bore halves compress against the shaft surfaces, generating a friction grip that transmits the rated torque without requiring any keyway or interference fit. This assembly method is particularly valuable in plant installations where shaft end access is restricted \u2014 above reactor vessels, between flanged connections, or in confined equipment rooms \u2014 because the coupling assembles laterally around the shaft rather than requiring axial shaft movement through the bore.<\/p>\n

The ability to disassemble the coupling without shaft modification is a significant maintenance advantage. When the coupling bolts are released, the two body halves separate cleanly, leaving both shaft surfaces intact and undamaged for reuse. This is in contrast to interference-fit or keyed hub connections, which typically require heat, pressing, or shaft modification to disassemble.

Split-Body Design and Operational Features<\/h2>\n

\"JQ-160<\/p>\n

The JQ-160’s split-body construction is the defining functional feature of the JQ series. Each half of the coupling body contains one full bore semicircle, and the two halves are precision-machined to mate at the split plane with minimal gap when the clamping bolts are torqued. The bore surface is machined to H7 tolerance as standard, providing a controlled interference-adjacent fit against the shaft end for maximum friction grip area. The clamping bolt arrangement \u2014 26 bolts distributed around the split flange \u2014 provides symmetric clamping force across the bore circumference, minimising the risk of shaft deflection or misalignment from uneven bolt loading.<\/p>\n

Installation requires no special tooling beyond a calibrated torque wrench. The two shaft ends are brought into position, the coupling halves are placed around them, and the bolts are tightened progressively in a cross pattern until the specified bolt torque is achieved on all fasteners. The specified body length L0 of 280 mm accommodates the gap between shaft ends inside the coupling. For non-standard shaft configurations where the gap dimension is critical, custom body lengths can be specified \u2014 contact our technical team<\/a> for assistance.<\/p>\n

Keyless Shaft Connection<\/h3>\n

No keyway required in either shaft section. The friction clamp transmits the full rated torque through the bore contact surface, eliminating the keyway stress concentration that contributes to shaft fatigue in keyed hub designs.<\/p>\n<\/div>\n

\n

Lateral Assembly<\/h3>\n

Assembles around the shaft from the side \u2014 no axial shaft movement required. Essential for installations in confined spaces, above reactor vessels, or between fixed-position flanges where end access is unavailable.<\/p>\n<\/div>\n

\n

Non-Destructive Disassembly<\/h3>\n

Both shaft ends are released undamaged when the clamping bolts are loosened. Shafts can be reused across multiple coupling replacements \u2014 reducing lifecycle shaft cost and maintenance downtime.<\/p>\n<\/div>\n

\n

Custom Bore Available<\/h3>\n

Non-standard bore diameters for vertical reducer output shafts can be specified at order time. Ever Power machines bores to the stated non-standard dimension, ensuring compatibility with custom gearbox output shafts without adapter sleeves.<\/p>\n<\/div>\n<\/div>\n
