Description
Version A: Standard version. The threaded spindle moves 1 mm inaxial direction with every full rotation of the worm shaft. The object to be moved must be secured against twisting. Housing: Made from aluminiumalloy in die-cast version. All sides machined. As standard filled withlubricant. Gearing: Worm made from ETG100, Gear made from Gbz12.Self-locking to a certain extend. Vibration, an increase in the spindlepitch or the use of rolling screw elements release the self-locking. Inthis case, e.g., a brake motor should be included in the system. Forlower stroke speeds, worm gear sets with higher transmission ratios canbe supplied on request. Spindle: Material C15, from size 4 C45.On request also available as left-hand, stainless steel or ball screwversion. Protective sleeve: The versions A and B are, unlessstated otherwise in the order, supplied with a protective sleeve. VersionA: With this standard version the threaded spindle moves 1 mm inaxial direction with every full rotation of the worm shaft. The spindlehas to be secured against twisting. Versions A and B are avaliable withan optional spindle end safety feature. This means the threaded spindleis locked before the safety sleeve is mounted, to limit the stroke inextended position so that the spindle cannot be screwed out of the gearunit. Attention: this safety feature means the safety sleeve is by about20 mm longer. The product numbers below only refer to the basic gearunits without spindle. Please ask for the price of the complete unitincluding spindle and accessories as, e.g., flange plate/travelling nut,bellow or coil spring cover, fastening strips.
