Vibration reduction supporting device used for sliding bearing

The invention provides a vibration reduction supporting device used for a sliding bearing, and relates to the sliding bearing. The vibration reduction supporting device comprises a bearing bush and vibration isolation assemblies. The bearing bush is a hollow cylinder. The vibration isolation assemblies are arranged on the outer ring of the bearing bush and each comprise two small bolts, a gasket B, a cover plate and a leaf spring. Each cover plate and the corresponding bearing bush are fixed through two large bolts which are in axial symmetry about the corresponding cover plate. The large bolts are sleeved with sleeves located in the cover plates. Gaskets A are arranged between the cover plates and the bearing bush and make contact with the gaskets B. The vibration reduction supporting device can be used for gearboxes supported by sliding bearings, the vibration problem of speed reducers can be effectively solved, the transmission quality is ensured, and the running reliability and the service life of the speed reducers and accelerators are not influenced. The vibration reduction supporting device is reasonable in structure, reliable in work and high in universality.
