[advertisement] NEW! Vertical Shaft Worm Drive Gearbox
« on: January 11, 2012, 08:32:03 AM »
Vertical Shaft Worm Drive Gearbox from ServoCity - only $59.99!
Introducing our new Vertical Shaft Worm-Drive Gearbox!  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.  We offer a wide range of compatible gearmotors to choose from - both our Precision Gearmotors and our Standard 3-12V Gearmotors will work with this gearbox (motor sold seperately).  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).

Hi,

Neither your post, nor the product page reveals anything on the material of the (rather narrow, non-) worm wheel, the maximum torque it can handle or the total insertion loss/efficiency - rather crucial info if you need something like this in the first place.
Would you care to share? :)
Regards,
Søren

A rather fast and fairly heavy robot with quite large wheels needs what? A lot of power?

The worm is constructed of stainless steel.  The worm gear that it meshes to is constructed of 1/8” acetyl which is attached to the 3/8” SS output shaft via a 3/8” set-screw hub.  The worm gear is a straight cut gear however it meshes well given the width (no need for a helical gear).  This product is designed to drastically slow down the rotation of a gearmotor for low speed applications (such as timelapse videography).  The intention was not for super high-torque applications as the set-screw hub will cause the worm gear to spin on the output shaft.  The worm drive gearbox is a brand new product; we do plan to release further data about it in the near future.
Thanks for your post.

Thanks for the info, unfortunately I need lots of torque for the app at hand.
