Two-Way, Three-Way & Counter-Rotating Standard Gearboxes
Two-Way Standard Gearbox
Crown Two-Way Gearboxes feature an “L” style design and are ideal for applications that require a single output shaft. These units feature a single input and single output shaft at a 90 degree angle to the input shaft. Special shaft options include Splined, Special Lengths, Drilled Holes, and more. These ultra-compact gearboxes are preferred in applications with limited space and where the primary and driven equipment need to be close to each other. Frequent industrial uses include Packaging Machinery, Printing & Converting and Food Processing Equipment.
Available Drive Sizes: Drives are available with shafts of 3/8”, 1/2", 5/8” and 3/4" diameter in both 1:1 and 2:1 ratios.
Three-Way Standard Gearbox
Crown Three-Way Gearboxes feature a “T” style design with two output shafts at 90 degrees from the input shaft, rotating in the same direction. This design allows for changes in axis rotation along with a smooth transfer of power and minimal backlash. Gearboxes are compact and feature multiple mounting options at any orientation. Three-way gearboxes utilize AGMA Class 10 spiral bevel gears with counter-rotating versions (where output shafts rotate in opposite directions simultaneously) available. Common three-way gearbox applications include Industrial Dryers, Folding Machines and Brushing Machinery.
Available Shaft Sizes: Standard shaft diameters include 3/8”, 1/2", 5/8”, 3/4", and 1”, and both 1:1 and 2:1 ratios are available.
Counter-Rotating Standard Gearbox
Crown Counter-Rotating Gearboxes have the same “T” style design as the Three-Way units, but are unique in that the two output shafts rotate in opposite directions simultaneously.
Available Shaft Sizes: Standard shaft diameters include 3/8”, 1/2”, and 5/8”, and both 1:1 and 2:1 ratios are available.
Several factors including preferred input-output ratio, drive type, shaft configuration and style are important when selecting the right gearbox for your application. Contact us today and let us help find which gearbox is right for you.
