Mechanical Actuation Systems Components

Joyce jacks, miter gear boxes, couplings and motorized ComDRIVE® jack/actuators can be used in a number of system arrangements. Because jacks selected for such systems have uniform lifting speeds and are fully synchronized, unevenly distributed loads can be raised, lowered and positioned in unison. Jacks of differing capacities may be used in the same system as long as driven shaft turns per 1" of travel are the same.

ComDRIVE® Motorized Screw Jack / Actuators Joyce ComDRIVE motorized jack/actuators are particularly effective in multiple jack systems. Because ComDRIVE combines motor, jack and reducer into a single unit, the number of gear boxes, shafts and couplings in most arrangements can be reduced.	Download detailed information
Miter Gear Boxes Joyce miter gear boxes are specifically engineered for use with Joyce screw jacks and actuators in multiple jacking systems. Miter gear boxes used in such systems effectively raise unevenly distributed loads. When driven shaft turns per inch of travel are the same, total synchronization is assured because all models have a uniform lifting speed. All standard Joyce miter gear boxes are 1:1 ratio, other ratios are available in the RC series units. Four-shaft units are also available in the RC-18 through RC-204 and the MK series.

Flexible Couplings Joyce/Dayton offers a full line of flexible couplings. Joyce Model S and Model F geared couplings offer greater torque capacity than ordinary couplings. More gear teeth around the inner circumference of the coupling, plus high torsional, radial and angular stiffness mean that you get a more durable coupling, with greater strength than many larger and more expensive couplings. Joyce Model S sleeve-type gear couplings are available in flex/rigid and full/flex configurations. Model F flange-type gear couplings offer superior radial-misalignment capability and radial flexibility. Model J jaw-type couplings are ideal for all kinds of general industrial applications, require no lubrication and are resistant to oil, grease, moisture and other contaminants.

Shafting Joyce shafting matches perfectly with Joyce screw jacks and couplings to meet a wide range of system requirements. Shafting is made from cold-finished C1018 steel, with ends machined to ANSI-standard keyways.	Download detailed information
