Abstract
Reinforced rubber seals are used in bearing assemblies. Their reliable operation is ensured by pressing the working edge of the seal to the shaft. The contact load in the connection is affected by the force generated by the band spring. The presented method is used to determine the specific contact load of the working edge of the seal on the shaft offered by the bracelet spring, depending on the parameters of the seals and springs. To check the adequacy of the methodology, the authors studied a batch of reinforced seals 1.1‑45×65‑1 GOST 8752‑79 in the amount of 25 pcs. Theoretical calculations of the contact force from the action of the spring were 2.64 to 3.804 N, specific contact loads – 0.098 to 0.153 N/mm, and according to experimental data – 2.75 to 3.50 N and 0.102 to 0.141 N/mm, respectively. High convergence confirms the correctness of the presented calculated dependencies. It has been established that the parameters of the seals have a large spread, which hampers accurate calculation of the specific load in the “shaft-seal” connection. To increase the accuracy of readings, it is necessary to reduce the tolerances on the dimensions of rubber products.
