Hola a todos. Estoy utilizando este reductor planetario de ángulo recto (https://www.oyostepper.com/category-192 ... arbox.html) en un mecanismo de elevación vertical; el eje de salida está orientado hacia abajo y sometido a tracción axial pura.
Tras dos meses de funcionamiento, apareció un ruido periódico de golpeteo. Al desmontarlo e inspeccionarlo, descubrí que la holgura (backlash) del engranaje cónico casi se había duplicado respecto a las especificaciones de fábrica, y observé zonas brillantes en las superficies de los dientes que indicaban una carga desigual.
Sospecho que la tracción axial se transmite desde el eje de salida al eje del engranaje cónico, provocando un ligero desplazamiento axial que altera la posición de engrane. Aunque instalé un rodamiento de empuje, la holgura sigue variando gradualmente.
Me gustaría pedir consejo sobre cómo diseñar el posicionamiento axial del engranaje cónico para una aplicación de elevación vertical. ¿Es necesario utilizar un muelle de precarga para contrarrestar la fuerza de tracción?
Gracias.

Hello everyone. I'm using this right-angle planetary reducer (https://www.oyostepper.com/category-192 ... arbox.htmlIn a vertical lifting mechanism, the output shaft is downward-facing and subjected to pure axial tension.
After two months of operation, a periodic knocking noise appeared. Upon disassembly and inspection, I found that the backlash of the bevel gear had almost doubled from the factory specifications, and I observed shiny areas on the tooth surfaces indicating uneven loading.
I suspect that the axial tension is being transmitted from the output shaft to the bevel gear shaft, causing a slight axial displacement that alters the meshing position. Although I installed a thrust bearing, the backlash continues to vary gradually.
I would like advice on how to design the axial positioning of the bevel gear for a vertical lifting application. Is it necessary to use a preload spring to counteract the tension force?
Thank you.
