As engineers, we all know how to quickly create a sketch of a gearbox or transmission using a few lines. Using maybe black for shafts, green for bearings, blue for gears and red to indicate the power flow. We do this to remember a great idea, communicate with customers or to pass time waiting at an airport.
KISSsoft emulates this approach in a much more orderly fashion. Using only the mouse, complex schematics can be drawn and edited, thereby converting the structure of a gearbox into a logical and 3D model. The schematic in the Sketcher also serves as a navigation and visualization tool and is complemented by an overview of some of the key data (e.g. module and number of teeth) of the components making up the gearbox.
It's no secret that cycloidal gearboxes are important in mechanical engineering, especially when it comes to precision motion control and efficient power transmission. The gear systems differ from harmonic wave/strain wave gearboxes by using a cycloidal disk and needle bearings to transmit torque with minimum backlash, achieve high reduction ratios, and support substantial loads. This Sumitomo Drive Technologies blog will talk about single-stage and multi-stage cycloidal gearboxes.
Gear backlash in precision applications is a critical element of gear system performance. Too much backlash can result in inefficiencies of motion in the gear train and will ultimately damage a gear’s teeth. Too little can mean the gears bind up and cause excessive wear to the tooth’s surface and the root of the gear, or even the fracturing of a tooth. Establishing and setting the appropriate amount of backlash is essential in gear design and manufacturing, according to Berg, a Regal Rexnord Brand.
