Abstract
Abstract
The article presents the results of solving the scientific problem of ensuring folding, which is complex and includes the appointment of optimal tolerances, maximum deviations and landings in the design. The authors presented for selection of locally loaded bearing rings the field of tolerances of holes and shafts depending on type of bearings, operating conditions and the nature of load. The authors consider the definition of the dynamic coefficient through the value of the landing on the minimum tension between the circulating load ring and the surface of the connected part. Checking the correctness of the choice of landing involves ensuring the condition of strength at the allowable tension. The authors determined the equivalent dynamic load for the established requirements for design of rolling bearings, taking into account the load variability of 6005 N and calculated the durability of 9500 hours. In article it is established that on diameters of openings of demountable cases under external rings with local loading it is expedient to assign fields of tolerances H6, H7, G6, G7. The article confirms the possibility of periodic rotation of the bearing ring during the operation of the folding unit and reduce the uneven wear of the raceways.
