Gear Motors – GEARBOXES – 51055
Geared motors are used in robotics where high torque is needed. A geared DC Motor has a gear assembly attached to the motor. The speed of motor is counted in terms of rotations of the shaft per minute and is termed as RPM .The gear assembly helps in increasing the torque and reducing the speed.
Using the correct combination of gears in a gear motor, its speed can be reduced to any desirable figure. This concept where gears reduce the speed of the vehicle but increase its torque is known as gear reduction.
When you need high torque at a relatively low shaft speed or RPM.
-AC gear motors can provide ample force to help operate lifts, medical tables, jacks and robotics.
-DC gear motors are typically used in automotive applications such as power winches on trucks, windshield wiper motors, power seats or power windows.
Twin-Motor Gearbox
This is a ready to assemble gearbox that uses two electric motors to independently control each of the output shafts. The gears and gear case are accurately molded from tough plastic for smooth and efficient operation. Two gear ratios, 207:1 or 58:1 can be selected.

6- Speed Gearbox
Gearbox can be assembled for six different gear ratios. Select one according to application before assembling. Gear ratio can be altered from 11.6:1 to 1300.9:1 by gear combinations. 3 volt RE-260 motor. Gear types include 8T, 36/14T, and a clutch. Gear box accepts 130 or 140 motor types. Other parts include a crossed horn and output shaft. Use cam for vertical movement or change to rectilinear movement. Grease included for lubrication, plus a hex wrench and small phillips screws.

Planetary Gearbox
A highly versatile system for reduction of high RPM electric motors to high-torque low RPM applications. Often used in precision instruments because of the reliability and accuracy of the unit. The RC-260 motor included in this set utilizes carbon brushes for long motor life. RC-260 motor operates on 3 volts. Combining the gearboxes in various ways enables 8 different gear ratios (4:1, 5:1, 16:1, 20:1, 25:1, 80:1, 100:1, 400:1). At a gear ration of 400:1 and voltage of 3V, the gearbox produces a torque of about 15 kg.

Vertical Shaft Worm Drive Gear Box
This gearbox utilizes a 30:1 ratio worm-drive reduction for applications that require extremely slow and smooth rotational motion. The worm-drive design not only minimizes backlash but also eliminates back-driving the gearmotor so a position can be held even when power is not applied. The precision ground 3/8” stainless steel output shaft is supported by dual 3/8” ABEC 5 ball bearings to support a load from any orientation.
The ¼” ABS plastic and aluminum structure provides a rigid framework without adding unnecessary weight and is easily mounted to any flat surface by utilizing the base mounting tabs. The Vertical Shaft Worm-Drive Gearbox is perfect for turn-tables, time-lapse systems and low-speed applications that require high precision and torque. Without a gearmotor, the system weighs only 0.375 lbs (5.9oz).
