其中，壳体1的轴向两端分别具有第一端壁111和第二端壁131，例如图1的示例中，壳体1可以包括第一壳体11、中间壳体12、第二壳体13，中间壳体12可以形成为圆筒形，从而圆筒形的中间壳体12可限定出一定的容纳空间，便于旋转式压缩机100内部的零部件(例如图1中所示的电机2和压缩机构3)的安装。
参考图1，第一壳体11(例如图1中所示上壳体)和第二壳体13(例如图1中所示下壳体)分别连接在中间壳体12的轴向两端，这样，第一端壁111可以为第一壳体11的底壁面，第二端壁131可以为第二壳体13的顶壁面。
进一步地，第一壳体11和第二壳体13中的任一个可以与中间壳体12一体成型，参考图1，第一壳体11可以与中间壳体12一体成型，从而在装配好零部件后，将中间壳体12与第二壳体13固定在一起，便于旋转式压缩机100的装配，提高生产效率。当然，第二壳体13也可以与中间壳体12一体成型，从而在装配好零部件后，将中间壳体12与第一壳体11固定在一起，完成旋转式压缩机100的装配。
具体地，电机2设在壳体1内，电机2包括定子铁芯21和转子铁芯22，在壳体1的轴向(例如图1中所示的上下方向)上、定子铁芯21的邻近第一端壁111的一侧端面与第一端壁111之间的最大距离为Dst，例如在图1的示例中，在上下方向上，定子铁芯21的上端面与第一端壁111之间的距离为Dst，这里需要说明的是，当第一壳体11为不规则形状的外形时，Dst则为定子铁芯21的上端面与第一壳体11的内侧壁之间的最大距离。
进一步地，压缩机构3设在壳体1内且位于电机2的远离第一端壁111的一侧，例如图1的示例中，压缩机构3可以设置在电机2的下方，从而压缩机构3较电机2远离第一端壁 111，且便于电机2和压缩机构3的安装和配合工作。
具体地，参考图1，压缩机构3包括气缸组件31和主轴承32，主轴承32连接在气缸组件31的邻近电机2的一侧端面(例如图1中所示的气缸组件31的上端面)上，在壳体1的轴向(例如图1中所示的上下方向)上、转子铁芯22的邻近第一端壁111的一侧端面与主轴承32的法兰部321的邻近第一端壁111的一侧端面之间的最小距离为Drt，例如在图1的示例中，转子铁芯22的上端面与主轴承32的法兰部321的最上端之间的距离为Drt。
其中，Dst和Drt满足关系：0.335≤Dst/Drt≤0.838，参考图5，这里需要说明的是，图5中的横坐标代表Dst/Drt的值，图5中的纵坐标α代表旋转式压缩机100工作时的噪音OA值，具体地，随着Dst/Drt的不断增大，旋转式压缩机100的工作噪音OA值先逐渐降低到一定程度，随后再逐渐的增大，通过对旋转式压缩机100的Dst/Drt比值的不同设计，会使得旋转式压缩机100具有不同的噪音，例如，Dst/Drt为0.4、0.45、0.55、0.6、0.75时，旋转式压缩机100的工作噪音都会得到有效地降低。
由此可知，通过将旋转式压缩机100的Dst/Drt值设置为：0.335≤Dst/Drt≤0.838，都会有效地降低旋转式压缩机100的工作噪音。
这里需要说明的是，电机2和压缩机构3可以均与壳体1同轴设置，也就是说，曲轴4的中心轴线与壳体1的中心轴线重合，从而转子铁芯22的旋转轴线与壳体1的中心轴线重合，主轴承32的中心轴线和气缸组件31的中心轴线也均与壳体1的中心轴线重合，这样，可使得旋转式压缩机100的结构简单合理，且便于旋转式压缩机100的装配。
根据本发明实施例的旋转式压缩机100，通过将Dst/Drt的值设置在合理的范围内，可有效地降低旋转式压缩机100工作时的噪音，使得旋转式压缩机100具有结构简单合理、装配简单以及有效地降低噪声等优点。
优选地，Dst和Drt进一步满足关系：0.568≤Dst/Drt≤0.680，例如，当Dst/Drt为0.58、0.6或0.65时，旋转式压缩机100的工作噪音接近最低，由此可知，通过将旋转式压缩机100的Dst/Drt值设置为：0.568≤Dst/Drt≤0.680，可进一步地降低旋转式压缩机100的工作噪音。
在本发明的一些实施例中，参考图1和图2，从压缩机构3排出的高温高压的冷媒会向上传动，转子铁芯22上形成有贯穿的通气孔221，从而可便于高温高压的冷媒的向上传动，降低噪音。
进一步地，通气孔221的中心轴线与转子铁芯22的旋转轴线平行，例如在图1的示例中，转子铁芯22的旋转轴线为上下方向，从而通气孔221的中心轴线也可以为上下方向， 从而进一步地便于高温高压的冷媒的向上传动，进一步有效地降低噪音。
在本发明的一些实施例中，通气孔221关于转子铁芯22的第一直径呈轴对称分布，通气孔221在第一直径方向上的宽度D满足：0.204mm≤D≤0.480mm，例如在图2的示例中，通气孔221可关于转子铁芯22的第一直径k对称设置，通气孔221在第一直径k上的宽度为D，参考图6，这里需要说明的是，图6中的横坐标代表D的值，图6中的纵坐标α代表旋转式压缩机100工作时的噪音OA值，具体地，随着D值的不断变大，转式压缩机100的工作噪音先逐渐降低到一定程度，随后再逐渐的增大，通过对旋转式压缩机100的通气孔221的D值的不同设计，会使得旋转式压缩机100具有不同的噪音，例如，D为0.25mm、0.35mm、0.41mm时，旋转式压缩机100的工作噪音都会得到有效地降低。
由此可知，通过将旋转式压缩机100的通气孔221的D值设置为：0.204mm≤D≤0.480mm，可以有效地降低旋转式压缩机100的工作噪音。
优选地，D进一步满足：0.404mm≤D≤0.460mm，例如，当D为0.41mm、0.43mm或0.45mm时，旋转式压缩机100的工作噪音接近最低，由此可知，通过将旋转式压缩机100的通气孔221的D值设置为：0.404mm≤D≤0.460mm，可进一步地降低旋转式压缩机100的工作噪音。
在本发明的一些实施例中，通气孔221的横截面的轮廓线可以形成为曲线或直线与曲线的结合，例如，通气孔221的横截面可以为空心弧形状(如图2中所示)，也可以为圆形(如图3中所示)，还可以为圆角矩形(如图4中所示)，从而便于高温高压的冷媒的流通，降低旋转式压缩机100的工作噪音。当然，本发明不限于此，通气孔221的横截面也可以是其他曲线或者直线与曲线的结合形状，以便更好地满足实际的使用需求。
在本发明的一些实施例中，在转子铁芯22的旋转轴线方向(例如图1中所示的上下方向)上、通气孔221的横截面形状、尺寸均相同，从而一方面便于通气孔221的加工，减少旋转式压缩机100的生产工艺复杂性，另一方面可使得高温高压的冷媒在通过通气孔221时的流动更加均匀，进一地降低旋转式压缩机100的工作噪音。
在本发明的一些实施例中，参考图2，通气孔221可以为多个且在转子铁芯22的周向上均匀地间隔开，也就是说，多个通气孔221在转子铁芯22的周向上均匀地间隔开设置，从而方便通气孔221的加工，且便于高温高压冷媒的流通。
进一步地，参考图2-图4，每个通气孔221的形状、尺寸均相同，从而进一步地方便通气孔221的加工，提高高温高压冷媒的流通均匀性，进而有效地降低旋转式压缩机100的工作噪音。
在本发明的一些实施例中，参考图1，转子铁芯22可转动地设在定子铁芯21的内侧，具体而言，定子铁芯21的外周壁可以与壳体1的内周壁固定，转子铁芯22可以与曲轴4热套相连，从而有效地提高电机2与压缩机构3的配合稳定性，且便于旋转式压缩机100的装配。当然，本发明不限于此，转子铁芯22也可以转动地设在定子铁芯21的外侧。
