Description

机舱罩装配及同轴度调整方法
技术领域
本发明涉及一种风电装配,尤其是一种机舱罩装配及同轴度调整方法。
背景技术
在风力发电机组整机装配过程中,塔筒需与偏航轴承同轴心,轮毂底面需与主轴端面同轴心,这就要求机舱罩塔筒密封刷环与偏航轴承、主轴密封刷环与主轴需要保证一定的同轴度,才能保证风力发电机组的正常运行。大部分机舱罩前侧部分不是单独结构,而是依附在左右侧板上,这种机舱罩结构的装配方案是将机舱罩各组成部分在主机上组好,再整体调整机舱罩塔筒密封刷环与偏航轴承的同轴度以及主轴密封刷环与主轴的同轴度,而由于机舱罩的整体结构,要同时保证这两个同轴度在要求范围内操作难度非常大,往往是主轴密封刷环与主轴的同轴度调整好之后,塔筒与偏航轴承的同轴度就会发生变化,而塔筒与偏航轴承的同轴度保证了之后,主轴密封刷环与主轴的同轴度又不符合要求,这样两个同轴度很难同时保证,对人力和物力的要求也很高,调整装配用时间很长。
发明内容
本发明的目的是为克服上述现有技术的不足,提供一种机舱罩装配及同轴度调整方法。
为实现上述目的,本发明采用下述技术方案:
一种机舱罩装配及同轴度调整方法,包括:
a)单独制作机舱罩前盖板,这样机舱罩的整体结构为左侧、右侧、前部以及顶部;
b)先将机舱罩左右侧装配到主机上,并通过螺栓连接左右侧法兰,通过测量机舱罩塔筒密封刷环与偏航轴承的距离调整好塔筒与偏航轴承的同轴度;
c)再装配前盖板,前盖板在装配过程中先不与机舱罩左右侧连接,直接通过测量调整好机舱罩前盖板密封刷环与主轴的距离,保证好前盖板密封刷环与主轴的同轴度后,利用机舱罩前盖板法兰上的螺栓孔对机舱罩左右侧法兰进行配钻,实现机舱罩左右与前盖板的螺栓连接,最后在各法兰连接部位涂抹密封胶以达到机舱罩密封效果,完成机舱罩的调整装配。
本发明为了改变现有技术的状况,提高工作效率,打破传统的制作装配思路,把机舱罩前侧板单独制作,这样机舱罩的大体结构就是左侧、右侧、前部以及顶部。而装配方案是先将机舱罩左右侧装配到主机上,调整好机舱罩塔筒密封刷环与偏航轴承的同轴度后再装配前盖板,而前盖板在装配过程中先不与机舱罩左右侧连接,直接通过测量调整好前盖板密封刷环与主轴距离,保证好前盖板主轴密封刷环与主轴的同轴度后再通过配钻实现前盖板与机舱罩 左右侧连接,最后再涂抹密封胶达到密封效果。此方案首先在制作工艺上优化了机舱罩结构,单独的前盖板制作也减化了左右侧的结构。机舱罩厂家在制作过程中节约了工序,产生了便利。其次对整机厂家进行机舱罩装配及调整同轴度过程产生了便利,只需保证塔筒与偏航轴承的同轴度即可。这种新型的装配方式大大的节约了时间,提高了生产效率。
本发明通过局部定位来达到装配要求。这样可以显著缩短机舱罩的装配时间,同时能够更精确地调整同轴度,采用这种新型的机舱罩制作、装配及调整方式解决了机舱罩无法同时保证两个同轴度的难题。这样就有效地优化了机舱罩的制作工艺,实现了机舱罩的快速装配,节约了机舱罩调整同轴度的装配时间,保证了装配精度,显著地提高了机舱罩装配效率。

具体实施方式
下面结合附图和实施例对本发明进一步说明。
通过局部定位来达到装配要求。这样可以显著缩短机舱罩的装配时间,同时能够更精确地调整同轴度,采用这种新型的机舱罩制作、装配及调整方式解决了机舱罩无法同时保证两个同轴度的难题。
1、如图(1)所示,新型机舱罩结构包括机舱罩左侧1、机舱罩右侧2、机舱罩顶盖3和机舱罩前盖板4。
2、如图(2)所示,在主机5上装配机舱罩左侧1和机舱罩右侧2,并通过螺栓连接左右侧法兰,通过测量机舱罩塔筒密封刷环与偏航轴承的距离调整好塔筒与偏航轴承的同轴度。
3、测量机舱罩前盖板4密封刷环与主轴6的距离,保证好前盖板密封刷环与主轴的同轴度后,利用机舱罩前盖板法兰上的螺栓孔7对机舱罩左右侧法兰进行配钻,实现与前盖板的螺栓连接,最后在各法兰连接部位涂抹密封胶以达到机舱罩密封效果,完成机舱罩的调整装配。
这样就有效地优化了机舱罩的制作工艺,实现了机舱罩的快速装配,节约了机舱罩调整同轴度的装配时间,保证了装配精度,显著地提高了机舱罩装配效率。
上述虽然结合附图对本发明的具体实施方式进行了描述,但并非对本发明保护范围的限制,所属领域技术人员应该明白,在本发明的技术方案的基础上,本领域技术人员不需要付出创造性劳动即可做出的各种修改或变形仍在本发明的保护范围以内。
