8、8.211.318.5Lenze7General dataWorm gearboxesStarting efficiency and self-lockingThe efficiency of a worm gearbox is determined among others by the speed ratios in the gearing and the state ofStarting efficiency ?A From the above, we can conclude that the efficiency ?A of a worm gearbox during startin
9、g is smaller than the operating efficiency ? at rated speed. Therefore the starting efficiency ?A must always be considered when starting under load is required. The following diagram shows the ?A values, which are to be expected as limit values after running in.Self locking: A worm gearbox is in a
10、self locking or irreversibility condition when no amount of torque applied to the worm wheel will rotate the worm shaft. We distinguish between static and dynamic self locking.Static self locking: In a static self locking condition it is not possible to start the driving worm wheel from standstill.
11、A self locking condition of the gearing can in some cases be counteracted by Starting efficiency ?ARatio ithe lubricant. In general, the efficiency increases with the gearbox size, increasing speed and decreasing ratio.shocks and/or vibrations in the gearbox so that it is possible to start driving t
12、he worm wheel! The static self locking can be checked roughly using the above diagram and the starting efficiency ?A. If ?A ? 0.5, a gearbox has static self locking.Dynamic self locking: The gearbox comes to a standstill even if a torque acts on the output side of the motor during disconnection. Dyn
13、amic self locking can be checked roughly using the total efficiency from the selection tables on pages 46/47. If ? ? 0.5, a gearbox has dynamic self locking. A precise check of static or dynamic self locking is possible in the factory, when the operating factors are known.Lenze8General dataAC-motors
