Полезная модель относится к машиностроению, в частности к устройствам, для приработки и повышения долговечности подшипника качения. Техническая задача, решаемая предлагаемым устройством, состоит в приработке и повышении долговечности подшипника качения путем подачи электролита (с компонентами анода, мелкодисперсными порошками) и прикладываемой нагрузки к подшипнику через корпус устройства. Поставленная техническая задача решается тем, что в известное устройство повышения долговечности, содержащее корпус, крышку, рабочий вал, подшипник качения, растворяющийся элемент - анод, гидронасос с емкостью, электролит, источник тока с регулятором, устанавливается в патрон токарно-винторезного станка, а к корпусу устройства прикладывают нагрузку в радиальном и осевом направлении в соответствии с центрами симметрии подшипника (в зависимости от типа подшипника качения).

The mechanical load on a rolling element bearing is determined from the deformation of the rolling element bearing. The local deformation caused by the rolling contact forces is used to determine an average contribution to the mechanical load in order to average out the effect on the deformation as a result of the spread in diameter of the rolling elements of the bearing. The global deformation of the rolling element bearing is determined to calculate a dynamic contribution to the mechanical load. The dynamic contribution takes into account the variations of the mechanical load on the relevant time-scales that have been omitted from the average contribution as a result of the averaging operation.

Автор: CLAASSEN Michael, LABELLE Chad, SHAIKH Shakeel
Принадлежит:

A method to ascertain measured friction torque to a bearing and a method to reduce preload variation of a hearing pair or set. Friction torque of a bearing is measured at a known load and speed. The value of the measured friction torque is then printed in a data matrix that is then applied to the bearing that was measured. Prior to assembling the bearings on a shaft system, the data matrix is read. The targeted friction torque is calculated for the shaft system based on the desired assembly preload. The bearing preload is then set and verified by measuring the friction torque of the pair of bearings assembled on the shaft. As a result of the method, bearing friction torque variation is substantially mitigated. 1. A method of ascertaining measured friction torque of a bearing , comprising the steps of:measuring fraction torque of the bearing at a known load and a known speed;entering the measured friction torque into a data matrix; andapplying the data matrix on the bearing.2.

A double parallelogram linear flexural system and method includes a first stage extending in a direction of movement, and a pair of parallelogram flexures extending from the first stage to distal ends configured for being grounded. A second stage extends parallel to the first stage, with another pair of parallelogram flexures extending between the stages, wherein the stages and parallelogram flexures form a double parallelogram. A linkage is disposed between, and resiliently coupled to, the stages. Linkage guiding flexures extend divergently from the linkage, to distal end portions configured for being grounded. The linkage guiding flexures define a notional triangle having a base extending between the distal end portions, and sides extending through proximal end portions to a notional apex defining a center of rotation for the linkage. The linkage is entirely within the double parallelogram, while constraining the stages to oscillate at the same frequency and phase. 1.
