Problems solved by technology

However, during the working process of the starter, there will be the impact of gear meshing during the process of the starter drive gear extending and retracting, so there will be teeth hitting and sweeping of the flywheel ring gear. After frequent starts and stops, the life of the flywheel ring gear Shortened, and because the replacement of the flywheel ring gear needs to be heated to achieve interference fit for installation, the process requirements are very strict, and there is no special equipment for external maintenance.
Therefore, only the entire flywheel and ring gear assembly can be replaced, and service and maintenance are difficult and costly

Embodiment Construction

[0027] A fixed-point flywheel ring gear structure with a split ring gear, including a starter drive gear 5, a starter drive gear telescopic control system, a driven gear 4, and a flywheel 1. The flywheel 1 is detachable and uniformly distributed with a number of Split ring gear 2; this embodiment is provided with two split ring gears 2 or three split ring gears 2 for the type of engine. If there are two split ring gears, then It is distributed at 180 degrees, corresponding to a four-cylinder engine (such as an in-line plane four-stroke four-cylinder engine); if there are three split ring gears 2, the three split ring gears 2 are distributed at 120 degrees, It corresponds to a six-cylinder engine (such as an in-line six-cylinder four-stroke engine). This is mainly to ensure that one of the split ring gears 2 can mesh with the driven gear 4 after stopping. The split ring gear 2 in this embodiment may contain 10-15 teeth or preferably 12 teeth. When connecting, in this embodime...

Abstract

The invention discloses a flywheel gear ring structure with split type gear rings at fixed points and an application method. The flywheel gear ring structure comprises a starter driving gear, a starter driving gear telescopic control system and a flywheel and further comprises the split type gear rings, the plurality of split type gear rings are detachably and evenly distributed on the flywheel, and the flywheel is further provided with a plurality of flywheel tightening holes. By adopting the flywheel gear ring structure and the method, the effects that the service maintenance difficulty is low, the cost is low, the flywheel gear ring is not prone to tooth breaking / tooth sweeping, and the reliability is good are achieved.

Description

technical field [0001] The invention relates to the technical field of engine flywheels, in particular to a flywheel ring gear structure and an application method with fixed-point belt split ring gears. Background technique [0002] The flywheel and ring gear assembly of the engine is mainly used as a kinetic energy storage, which plays the role of assisting the engine to start, keeping the crankshaft running evenly, and stabilizing the crankshaft speed. Among them, the flywheel ring gear should be able to reliably transmit the output torque of the starter motor, and drive the crankshaft to rotate to start the engine. Once the flywheel ring gear cannot reliably transmit the output torque of the starter, the engine will be difficult to start. Can't even start. Therefore, the flywheel and the ring gear assembly play an important role in ensuring the normal operation of the engine. [0003] The existing flywheel and ring gear assembly is mainly composed of two parts, the fly...
