Support platform for installing and disassembling diesel engine crankshaft vibration reducer

Abstract

The invention discloses a support platform for installing and disassembling a diesel engine crankshaft vibration reducer. The support platform comprises an axial V-shaped groove for supporting the vibration reducer, a horizontal movable table, and a hydraulic lifting device positioned below the horizontal movable table; a first slide block extends below the axial V-shaped groove; and a first chute matched with the first slide block for use is formed in the horizontal movable table. The support platform for installing and disassembling the diesel engine crankshaft vibration reducer has such advantages as simple structure, convenience for operation, high installation efficiency and good safety, supports and fixes the vibration reducer, enhances the balance of the vibration reducer in the installation process, and prevents the lifting of the vibration reducer; and the transverse motion of the axial V-shaped groove and a lifting mechanism can realize automatic centering of an inner hole of the vibration reducer and the axis of a crankshaft in all directions so as to quickly finish the coaxiality matching of the inner hole of the vibration reducer and the crankshaft.

Description

technical field [0001] The invention relates to a support platform for assembly and disassembly of diesel engine crankshaft shock absorbers, belonging to the field of support platforms for assembly and disassembly of large marine diesel engine crankshaft shock absorbers. Background technique [0002] Installing a shock absorber at the front end of the crankshaft is one of the most effective measures to reduce the vibration of the crankshaft. Commonly used diesel engine shock absorbers include low-speed silicone oil shock absorbers, medium-high spring shock absorbers, and high-speed diaphragm shock absorbers. When the diesel engine is working, the shock absorber can absorb a large amount of energy of the torsional vibration of the crankshaft system, thereby slowing down the torsional vibration of the crankshaft, and usually adopts a conical interference fit connection. The stability of the assembly and disassembly process of the shock absorber is conducive to improving the as...

AI Technical Summary

Problems solved by technology

However, the traditional manual crankshaft shock absorber installation method is difficult to achieve accurate positioning of the pin hole, and positioning tooling is required for secondary positioning of the pin hole. When the error is large, the shock absorber needs to be manually rotated. The operation process is complicated and the efficiency It is not high, especially the crankshaft and shock absorber connected by conical interference fit, which is easy to cause scratches on the inner hole of the crankshaft and shock absorber. A workbench with adjustable spatial position is urgently needed
