Engine reverse mounting emergency standby starting gear

Abstract

The invention relates to an engine reverse mounting emergency standby starting gear. The engine reverse mounting emergency standby starting gear comprises an engine, a flywheel ring gear, a flywheel shell, a flywheel driving gear and a starter. The flywheel ring gear is mounted in the flywheel shell and located at the rear end of the engine. A mass-produced automobile engine is used as the engine.A mechanical starter is used as the starter. A reverse mounting flange is arranged on the side, away from the engine, of the flywheel shell. The starter is mounted on the reverse mounting flange. Asviewed from the rear, when the engine is started, the flywheel driving gear pushes ahead from the rear and is engaged with the flywheel ring gear, the flywheel ring gear rotates anticlockwise, and theflywheel driving gear rotates clockwise. The mature and mass-produced automobile engine is used as the emergency engine directly and becomes power of emergency engineering machinery with two startingdevices on the premise that normal starting of the engine is achieved without redesigning the engine.

Description

technical field [0001] The invention relates to the technical field of engine emergency starting, and is suitable for use in occasions where the installation space of a second set of starting device (that is, an emergency standby starting device) is limited. Background technique [0002] At present, the starters of all engines are arranged according to the design of traditional automobile engines, such as figure 1 , figure 2 As shown, its starter 5 is arranged in parallel with the crankshaft of engine 1, and is installed in flywheel housing 3 front ends. When starting the engine, the flywheel drive gear 4 moves backwards to mesh with the engine flywheel ring gear 2, and rotates in the opposite direction to the engine's working direction to provide the kinetic energy required for engine starting. This traditional starter installation method is called "Formal dress". [0003] In today's internal combustion engine market, mature and mass-produced automotive engines are not ...

AI Technical Summary

Problems solved by technology

Based on traditional design and thinking, if two sets of starting devices are required, the engine must be redesigned. For example, the newly designed large-scale construction machinery and marine emergency engines have vacated the drive end and installed a spare starting device. Reduced product development cycle and manufacturing costs

Conventional automobile engines, especially small high-speed engines, are very suitable for emergency rescue, but the diameter of the flywheel housing is small, and there is no reserved space at the front end, resulting in no solution for the second set of starters due to the limited position
