All AndyMark gearboxes require grease for proper operation and long life. We suggest using our red tacky grease, . We also encourage that the user powers the gearbox continuously for 30 minutes without grease to allow the gear teeth to wear in. While we do design with short run times in mind, this 'run in' period for smooth gearbox operation, is recommended. Once this is completed, thoroughly grease the gear teeth periodically to ensure smooth operation.
Here is a right angle gearbox using steel bevel gears, designed to integrate with a CIM Motor, an AM Planetary gearbox, or a CIM-Sim. We suggest using this gearbox for applications where space is limited and you don't wish to locate a CIM Motor directly in line with the input shaft of a rotating device.
An E4T encoder can be added to the side of this gearbox, but is not included.
The AM Planetary gearbox output shaft will need to be cut down about 1/4" to fit properly.

LJ: Larry JonesThis product is named after Larry Jones, the uncle of AndyMark president Andy Baker. He passed away during the fall of 2013. He was the main inspiration to Andy in becoming an engineer, and is one of Andy's heroes. Larry grew up in Indiana and was a graduate of Purdue University and worked on many projects during his lifetime, including designing lawn tractors and military training devices. He enjoyed his profession, working as an engineering manager at Wheelhorse, Jet Propulsion Laboratory and Caltech. For the past two decades, Larry worked on the LIGO project as a mechanical engineer. This project includes very large installations of lasers, mirrors and detection equipment which culminate in the goal of detecting gravity waves.
Larry was gifted in not only being a technically sound engineer, but also was a master communicator. He could easily explain the most complex systems and theories so that a child could understand what he was explaining. He would tell stories in a way which would capture the attention of his grandchildren, nieces and nephews, all while displaying his charismatic smile.
Most importantly, Larry was a devoted and faithful husband, father, and leader. His community involvement, church leadership, and care for his family was inspirational to all who had the pleasure to know Larry. Naming this gearbox after Larry is a small token to pay tribute to a great man. Rest in peace, Uncle Larry.

ability to convert to 1/2 hex or to use 10 mm input would be a significant improvement. A drilled center hole to allow for removal of gear would be helpful.

This is a solid gearbox and works really well for direct drive. It's a bit of a pain to put together though. It would be even better if it came with plexiglas covers to place on either side to keep debris out of the gears.
