Centrifugal balance device of single-cylinder low-speed diesel engine

Abstract

The invention provides a centrifugal balance device of a single-cylinder low-speed diesel engine. The centrifugal balance device comprises a crankshaft, a crank arm, gears mounted on the crankshaft in a sleeving manner as well as a flywheel fixedly connected with one end of the crankshaft. The centrifugal balance device is characterized in that a flywheel-end balance weight is fixedly connected onto the rim of the flywheel, a free-end flywheel is fixedly connected to the other end of the crankshaft, and a free-end balance weight is fixedly connected onto the rim of the free-end flywheel. The centrifugal balance device of the single-cylinder low-speed diesel engine is simple in structure, the single-cylinder diesel engine is enabled to be compact in structure and small in size through the designed structure integrating the balance weights and the flywheels, and the balance problem is solved.

Description

technical field [0001] The invention relates to a centrifugal balance device, in particular to a centrifugal balance device for a single-cylinder low-speed diesel engine. Background technique [0002] Diesel engine balance means that when it is running in a stable condition, if the magnitude and direction of the force transmitted to the base do not change with time, the diesel engine is said to be balanced. However, due to the periodicity of the working process and the periodicity of the movement of the reciprocating internal combustion engine, the rotational inertial force and reciprocating inertial force generated during operation all change periodically. If these forces cannot cancel each other out in the machine, the force transmitted to the machine base will also change continuously. Furthermore, due to the fluctuation of the output torque, the change of the reaction force will also be caused, and these are the reasons for the unbalance of the reciprocating internal co...

Problems solved by technology

In this way, not only the wear and tear of the parts of the diesel engine will be increased, but the life will be reduced; the noise will increase, and the working conditions will deteriorate, so as to affect the normal operation of the matching power device and related instruments; and resonance may occur, leading to more serious destructive accidents

At the same time, this vibration also consumes a certain amount of energy and reduces the economic performance of the diesel engine.

[0003] Chinese patent (publication number CN1037762A) proposes a kind of balancing device suitable for double-cylinder and four-cylinder stroke diesel engine reciprocating force couple in a kind of balancing device of multi-cylinder diesel engine, mainly is to attach appropriate eccentric mass at both ends of the crankshaft, so that the crankshaft forms A set of additional force couples, and a balance shaft parallel to the camshaft to ensure balance; Chinese patent (notification number CN201884555U) is a vertical single-cylinder diesel engine balance device, and an auxiliary balance device is added on the basis of the original main balance device , although it can solve the balance problem of the diesel engine, the structure is relatively complicated and the volume is relatively large
