Abstract:
A significant proportion of the costs and downtime for repairs are attributed to transmission units, including the gearbox. One of the main reasons for such high transmission costs is the existing structure of the operating and repair cycle, which uses a strategy of waiting for failure, as a result operability is ensured mainly through overhaul and comprehensive maintenance with high consumption of spare parts. spare parts and repair downtime. This article is devoted to one of the most expensive repairs for ZF gearboxes, associated with the destruction of the front bearing of the output shaft. When inspecting gearboxes delivered with a similar defect, the condition of the gearbox parts does not allow making an unambiguous decision on the cause of the defect due to critical destruction of the mating parts. Based on the available research and scientific literature in the field of gearbox operation, an analysis was carried out and the root causes of gearbox failure in operation were ide
ntified.
