RACK JACK Synchronous Lifting Systems

RACK JACK (ROUND RACK TYPE) Operation The Rack Jack from WMH Herion provides simple synchronous lifting motion. The system of rack and pinion transforms linear motion to rotation and vice versa. The force-locked connection between the lifters or drive components is achieved by shafts with round profiles. The rack jacks are available with one or two racks. In the double version, the racks move in opposite directions. This simple mechanical principle ensures a failure-free, durable and reliable operation of the product. Thanks to its compact construction in robust square housings, the lifters...

TECHNICAL DATA - ROUND RACKS In the rack jack, the racks transfer tension and compression forces; they do not accept transverse forces. Slide bushings are used to support the racks. Straight teeth Pressure angle 20° Toothing quality 8 h27 Outer diameter is ground h6 acc. to customer specifications, please state the required number of teeth in your request & order z: Number of teeth p: Pitch ETG® 100 is a high-quality alloy steel with a tensile strength of 960-1100 N/mm2. The standard design of the rack includes a mounting thread (M x t, stated in the table) on both ends. Please inquire for...

RACK JACK (ROUND RACK TYPE) WITH DOUBLE SIDED TOOTHED RACK The concept of the classic Rack Jack is developed further in the Rack Jack with double sided toothed rack. Due to the design of the rack with double sided toothing, it is possible to transmit up to twice as high a load with the same rack diameter while keeping the moving mass of the rack comparatively low at the same time. This is particularly advantageous in applications with faster, shorter and dynamic strokes, since the moving mass is lower. In addition, a very balanced power ratio is achieved by the introduction of forces on two...
