the operating efciency rating ≤ 0.5. This takes effect in worm gearboxes (according to the prevailing surface quality and toothbearing size at centre-increase angles ranging from = 2.5° to 4°. Self-locking worm gearboxes are inefcient due to their poor overall efciency rating and the correspondingly high loss of output (particularly considering the extensive installation space and long power-on times). In those actuator situations in which the self-locking effect is required, one should always verify whether the installation of a return block or a brake is the more practical solution. A self-locking...
