Direct mounted (DM) type sprag clutches are specially designed for use as Backstops where for compactness of design it is necessary to mount the clutches so that an existing shafts serves as the inner race.This type of clutch is suitable for use in Gear Boxes and similar equipment where concentricity between shaft and housing is assured with the help of bearings and adequate lubrications is available . To ensure satisfactory performance of these units ,it is particularly recommended that 'PERCISION' review that working conditions and mounting arrangements. |
The shaft which acts as an inner race should be hardned to case depth of 1.2 mm after grinding .Surface hardness should be 60-62 HRC and core hardness should be 35-45 HRC .Surface finish of the shaft should be concentric within 0.02 mm.The clutch should be push fit (without pressing)in the housing bore shaft end should have 3 mm long chamt\fer at 15 ° angle to ensure easy mounting of the clutch. |
