Stackerbox
Product Description
Single Stage Spur Gearbox
Standard reduction: 3.57:1
Input Shaft: 3/8 inch diameter steel shaft, w/ 3/32" keyway
Output Shaft: same as input
Gear 1: 14 tooth, 20 dp, 14.5 pa
Gear 2: 50 tooth, 20 dp, 14.5 pa
Side plate material: clear polycarbonate, 1/4" thick
Body Material: 5"x3"x1/2" rectangle extrusion, 1/8" wall thickness
Weight: 0.95 pound
The design intent of this gearbox is twofold:
1. It provides a simple, single-stage reduction.
2. Multiple gearboxes can be stacked together and assembled with longer screws, creating a much higher reduction.
Mounting holes are present so a small CIM motor can be mounted as an input device. A 14 tooth CIM Gear (and hardware) would need to be purchased additionally to make this work. Simply remove the 3/8" input shaft, 14 tooth gear with 3/8" bore, and the 2 bearings on the input shaft before inserting the motor and the 14 tooth CIM gear.
When stacked together, 2 #10 washers are needed to space the gearboxes slightly apart so that the shaft ends do not contact each other.
If you are stacking 2 of these gearboxes together, use 4 - #10 (or M5) screws that are 2.5" long. If you are stacking 3 gearboxes, then use 4 screws that are 3.5" long.
