hydraulic coupling failure analysis

Hydraulic coupling PTO shaft itself is cantilevered and radial thrust bearing , this support structure in the installation , the response bearing clearance and bevel gear gap to be adjusted to ensure correct meshing . Bearing wear , it must be timely adjustment and replacement.Hydraulic pipe fittings , once the gap becomes large , so damage to the normal meshing bevel gears , causing additional load , resulting in deterioration of working conditions bearings , gear teeth , the bend axis limp . If you belong to the working machine load sudden overload situation , you can install the output shaft torque limiter or safety couplings. Conveyor shaft bevel gear reducer and hydraulic coupler is fitted together , the structure is irrational, weight, and easy installation and removal process caused by the collision axis bending deformation ; factory fluid coupling is for only for static balance test , at high speed , because the added unbalanced loads and shaft vibration , deterioration of the operating state of the shaft .
