Description

手拉启动的发动机 技术领域
本发明涉及一种发动机的起动结构，尤其涉及一种发动机的手拉启动结构。
 背景技术
手启动机构是设置在发动机曲轴一端用于启动发动机的一组零部件的组合，主要包括启动器、启动杯、飞轮和曲轴。发动机起动时，拉动启动器的拉绳手柄，启动器上的棘爪与启动杯结合带动启动杯转动，启动杯再带动飞轮和曲轴转动，从而启动发动机。
目前，大排量双缸发动机的起动系统多仅为电启动方式，少数配有手起动，且该手起动设计较为复杂且成本较高。尽管大发动机使用手起动机会不多，但是在一些交通不便及偏远地区等特殊使用环境中，为了防止电瓶电量不足造成无法启动，高性价比的手起动就成为必要配置。现有技术中，针对不同型号的发动机型，其启动拉盘、启动杯的高度、大小是不同的，现有启动拉盘和启动杯小于大排量双缸发动机上的需求，若采将现有启动拉盘和启动杯安装在大排量双缸发动机上，启动拉盘的安装座比风扇罩小，出现无法安装的问题；，启动杯安装到飞轮上时，将导致启动杯的安装位置过低，会导致启动杯无法与启动拉盘的起动机构形成配合的问题，因此现有的启动拉盘及启动杯将不满足双缸发动机的手启动需求，不能实现不同型号启动拉盘及启动杯的通用性。若重新设计启动拉盘和启动杯，则启动拉盘和启动杯的高度都需要增加，则可能导致启动拉盘和启动杯的强度不够。
基于以上问题，本发明提供了一种手拉启动的发动机。该手拉启动的发动机利于解决针对不同型号的启动拉盘和启动杯的通用性问题，同时避免了启动拉盘和启动杯高度拉伸后强度不够的问题，启动杯和启动拉盘均可配置现有产品规格，利于满足客户对不同启动拉盘及不同手柄方向的多重需求，性价比高，适用性广；且利于增加进风量满足大排量发动机的冷却需求，利于提高使用寿命。
