Shot blasting machine hook seals improve himself

Hook shot blasting machine sealing improve himself - 2021 01 - 07 Wang Donglin ( Shaanxi international) Problem description and the reason analysis of shot blasting machine hook bearing naked, steel shot easily into the dust, causing frequent bearing damage, hang fall, blasting process repeatedly damaged sand leakage board. 1 improvement scheme and implementation. Make the sealing flange, ensure the sealed bearing working environment. 2. Will use the original 8106 bearing replacement for 8210 bearing, increase linked with axial bearing capacity. 3. Choose 3 t hook used to connect the electric hoist lifting pulley, designed and manufactured flange diameter 220 mm 2 parts, flange between using the button to cooperate, selects the M16 bolts pressure. 4. Processing staircase shaft 1 piece, the maximum 89 mm for the cylindrical pressure bearing, bearing a diameter of 50 mm to install 8210 bearings, flange with hooks on to welding, flange processed under the hole, guarantee the ladder shaft flexible rotation. 5. Require all full weld seam, hook load flexible rotation, sealed bearing work environment, late convenient maintenance, reliable lubrication. To improve the effect and benefit hook improvement after put an end to hang fall, reduce downtime. A single save maintenance cost 8110 yuan, later all the shot blasting machine can be applied.
