58 tel: +44 (0)1992 509888 5 gear couplers (series nsg) huco nylon sleeve gear (nsg) couplers are compact and efficient units capable of transmitting a high level of torque relative to their size and weight. the couplers operate silently, are electrically isolating and maintenance free. they are marginally shock absorbent and easily installed in confined spaces. also directly interchangeable with some other makes. features high torque capability angular, parallel and longitudinal shaft misalignment maintenance free easy assembly compact, lightweight design with low inertia nsg couplers consist of two identical steel hubs with double crowned teeth which engage in a moulded polyamide sleeve to provide a double cardan coupling. the tooth form in combination with the moulded nylon sleeve allows angular and parallel misalignment of the two shafts, in addition to which the hubs are free to move longitudinally to accommodate end float. performance 1 angular misalignment capability 1mm longitudinal displacement up to 0.7mm parallel misalignment capability the.couplers are suitable for full load operation at temperatures ranging from 25 c to 100 c using a standard nylon sleeve, and special sleeves are available for operating in temperatures up to 125 c. friction between the mating teeth of the sleeve and hub is minimised by the smooth surface finish. the large tooth contact area also provides low contact pressure, reducing stress under misalignment conditions, and the load is distributed near the centre of the tooth for maximum strength. selection for even running applications eg. electric motor drives, select a coupler with a nominal kw/rpm rating which equates to that of the prime mover. for other drives, eg. gearbox outputs i.c. engines, positive displacement pumps or compressors, consider start-up loads, impact loads and normal running loads and resolve each to a torque value. in general: 1. nominal torque ratings allow for 82 c ambient, full misalignment and/or maximum rpm. 2. starting torque and braking loads should not exceed listed maximum torque. 3. intermittent, transient peak loads should not exceed three times nominal torque. 4. applications with uniform loading, well aligned shafts and low speeds will allow for operation at maximum torque levels. torque nm kw/1000 rpm max max misalignment moment coupler rpm compensation of size nominal max nominal max 000 parallel angular axial inertia weight per hub kgcm* kg** 14/40 10 20 1.0 2.1 14 0.3 0.24 0.18 19/48 15 30 1.6 3.1 11.8 0.3 0.47 0.27 24/52 21 42 2.2 4.4 10.5 0.4 0.93 0.36 28/66 45 90 4.7 9.4 8.5 0.4 3.09 0.82 32/76 60 120 6.3 12.6 7.6 0.4 1 1 5.48 1.45 38/83 81 162 8.5 17.0 6.7 0.4 8.68 1.82 42/92 100 200 10.5 20.9 6.0 0.4 14.28 2.00 48/100 142 285 14.9 29.8 5.6 0.4 18.34 2.45 65/140 380 760 39.8 79.6 4.0 0.6 109.57 8.50 80/175 700 1400 73.3 146.6 3.1 0.7 400.00 18.60 *values apply to maximum bore without keyway. ** values apply to hubs with pilot bores.
