Description

Flywheel of diesel engine Technical Field The utility model relates to the technical field of engines, in particular to the technical field of flywheels. Background The flywheel is a mechanical device for storing rotational kinetic energy in rotational motion, the flywheel is prone to resist the change of rotational speed, when a power source acts on the rotational shaft with a variable moment (such as a reciprocating engine), or when the power source acts on the rotational shaft with an intermittent load (such as a piston or a punch press), the flywheel can reduce the fluctuation of the rotational speed, so that the rotational motion is smoother, some tests require intermittent high-power output, if the power is directly provided by an electric power system, unwanted current surge can be caused, if the power is used with the flywheel, the flywheel can convert the redundant energy into the kinetic energy of the flywheel and accelerate the flywheel when the input work is larger than the output work, and the flywheel can slow down when the input work is smaller than the output work, and the released kinetic energy can become the output of the power. The prior patent CN212004104U discloses a flywheel assembly of a diesel engine, which balances the inertial force of flywheel rotation through reasonable distribution of the weight-reducing grooves, but the weight-reducing grooves cannot be adjusted once the processing is completed, and errors are unavoidable in the processing process, so that the balance of the inertial force of flywheel rotation cannot be adjusted after the production is completed. Disclosure of Invention The utility model aims to solve the problems in the prior art and provides the flywheel of the diesel engine, so that the flywheel can conveniently balance the weight, and the structure is simpler. In order to achieve the above purpose, the utility model provides a diesel engine flywheel, which comprises a flywheel main body, threaded holes, fixing bolts and a counterweight column, wherein one end of the flywheel main body is provided with a plurality of threaded holes, the threaded holes are screwed with the fixing bolts, each fixing bolt consists of a bolt head and a screw rod, the screws are all screwed into the threaded holes, the length of each screw rod is smaller than the depth of each threaded hole, the tail end of each screw rod is provided with a jack, the counterweight column is inserted into each jack, a spring in a compressed state is arranged between the counterweight column and the bottom of each jack, and the tail end of each counterweight column abuts against the bottom of each threaded hole. Preferably, the central axis of the threaded hole is parallel to the central axis of the flywheel main body, and the threaded hole uniformly surrounds the periphery of the central axis of the flywheel main body. Preferably, one end of the flywheel main body is provided with an annular groove, the annular groove and the flywheel main body are positioned on the same central axis, the threaded hole is formed in the groove bottom of the annular groove, and the thickness of the bolt head is smaller than the depth of the annular groove. Preferably, the inner wall of the jack is provided with a plurality of guide strips, the guide strips are parallel to the screw rod, the outer wall of the counterweight column is provided with a plurality of guide grooves corresponding to the guide strips one by one, the guide grooves are matched with the guide strips, and the guide strips are inserted into the guide grooves. Preferably, the outer side of the flywheel main body comprises a circle of flywheel teeth, one end of the flywheel main body is provided with a central hole and a plurality of crankshaft mounting holes, the other end of the flywheel main body is provided with a main mounting hole, the central hole and the flywheel main body are positioned on the same central axis, and the crankshaft mounting holes evenly encircle the periphery of the central hole. Preferably, the threaded hole and the central hole are located at the same end of the flywheel main body. The utility model has the beneficial effects that through matching the threaded holes, the fixing bolts and the counterweight columns, the flywheel can balance the inertial force of the rotation of the flywheel by using the proper counterweight columns in different threaded holes, the adjustment is more convenient, and the adjustment is more flexible.
