Long-stroke engine crankshaft assembled in split mode

Abstract

The invention discloses a long-stroke engine crankshaft assembled in a split mode. The crankshaft comprises a crankshaft main body, a first balance weight, a connecting rod journal and a second balance weight, a first clamping block is integrally formed at one end of the crankshaft main body, a through groove is formed in the first clamping block in a penetrating mode, a first containing groove isformed in the side of the through groove, a first extruding spring is integrally formed and connected into the first containing groove, a first extruding block is integrally formed and connected to the other end of the first extruding spring, the first extruding block is slidably connected into the first containing groove, and a first slope is arranged at other end of the first extruding block. According to the crankshaft, on one hand, split assembling and disassembling on the crankshaft can be achieved, connecting and assembling on crankshaft fasteners are convenient and fast, and the working efficiency of assembling is improved; and on the other hand, for the disassembling and maintaining of the crankshaft in the later period, the crankshaft does not need to be integrally disassembled,and targeted disassembling, overhauling and maintaining can be achieved, so that the convenience is brought to workers, and the economic benefits of maintaining work are improved.

Description

technical field [0001] The invention relates to the technical field of engine devices, in particular to a split-mounted long-stroke engine crankshaft. Background technique [0002] The crankshaft is the most important part of the engine; it bears the force transmitted by the connecting rod and converts it into torque through the crankshaft output and drives other accessories on the engine; the crankshaft is subject to the centrifugal force of the rotating mass, the periodically changing gas inertial force and The combined action of reciprocating inertial force makes the crank bearing subject to the bending and torsional load; therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface needs to be wear-resistant, work uniformly, and have good balance, in order to reduce the mass of the crankshaft and the movement of the crankshaft. The crankshaft journal is often made hollow; there are oil holes on the surface of each journal to int...

Problems solved by technology

[0003] When working, usually the piston pushes the connecting rod, and the connecting rod then pushes the crankshaft to rotate to provide power. It is very troublesome to install the connecting rod journal and connecting rod on the crankshaft, and it is very difficult for the disassembly and maintenance of the crankshaft in the later stage. Removing it as a whole is very inconvenient for maintenance work, wastes working time, and reduces work economic benefits. Therefore, the present invention proposes a split-installed long-stroke engine crankshaft to solve the above problems
