Description

防护型链轮
技术领域
本发明涉及链轮领域，尤其是防护型链轮。
背景技术
链轮是一种挂设链条之后，通过旋转来驱动链条的装置。但是现有的链轮容易因为受到外力撞击而发生形变。
发明内容
为了克服现有的链轮没有防护的不足，本发明提供了防护型链轮。
本发明解决其技术问题所采用的技术方案是：一种防护型链轮，包括轮体和轮齿，轮体上均匀分布有轮齿，所述轮体的正反两平面上均连接有防护机构，防护机构由防护壳，防护壳滑配连接在轮体的平面上，防护壳为环形壳体，防护壳内固定有防护层一、防护层二、伸缩杆，伸缩杆一端固定在防护壳上，伸缩杆另一端固定在轮体的平面上，防护层二与轮体的平面之间连接有弹性装置，伸缩杆穿过防护层一、防护层二、弹性装置。
根据本发明的另一个实施例，进一步包括所述防护层一为石棉层。
根据本发明的另一个实施例，进一步包括防护层二为橡胶层。
根据本发明的另一个实施例，进一步包括所述轮体的平面上固定有滑槽，防护壳上固定有滑块，滑块与滑槽相配合。
根据本发明的另一个实施例，进一步包括所述伸缩杆由活塞杆和筒体组成，活塞杆顶端穿入筒体内，活塞杆顶端固定有限位环，限位环无法穿过筒体的开口，筒体顶端焊接在防护壳内，活塞杆底端焊接在轮体的平面上。
根据本发明的另一个实施例，进一步包括所述弹性装置为弹簧。
本发明的有益效果是，该发明能够通过可以滑动的防护壳为轮体进行左右两侧面的防护。通过弹性装置来提供缓冲，通过防护层一来作为隔热防护用。通过防护层二来作为弹性支撑的作用。提高了链轮的防护性。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明的结构示意图；
图2是本发明的防护壳的剖视图；
图3是本发明的伸缩杆的剖视图；
图中1. 轮体，2. 轮齿，3. 防护壳，4. 防护层一，5. 防护层二，6. 伸缩杆，7. 弹性装置，8. 滑槽，9. 滑块，61. 活塞杆，62. 筒体。
具体实施方式
图1是本发明的结构示意图，图2是本发明的防护壳的剖视图，图3是本发明的伸缩杆的剖视图。一种防护型链轮，包括轮体1和轮齿2，轮体1上均匀分布有轮齿2，所述轮体1的正反两平面上均连接有防护机构，防护机构由防护壳3，防护壳3滑配连接在轮体1的平面上，防护壳3为环形壳体，防护壳3内固定有防护层一4、防护层二5、伸缩杆6，伸缩杆6一端固定在防护壳3上，伸缩杆6另一端固定在轮体1的平面上，防护层二5与轮体1的平面之间连接有弹性装置7，伸缩杆6穿过防护层一4、防护层二5、弹性装置7。所述防护层一4为石棉层。防护层二5为橡胶层。所述轮体1的平面上固定有滑槽8，防护壳3上固定有滑块9，滑块9与滑槽8相配合。所述伸缩杆6由活塞杆61和筒体62组成，活塞杆61顶端穿入筒体62内，活塞杆61顶端固定有限位环，限位环无法穿过筒体62的开口，筒体62顶端焊接在防护壳3内，活塞杆61底端焊接在轮体1的平面上。所述弹性装置7为弹簧。
结合附图1、附图2和附图3所示，当外部有物体冲击轮体1的两侧时，会首先碰触到防护壳3。防护壳3会往轮体1的方向滑动。在滑动的过程中，防护壳3上的滑块9沿着滑槽8进行直线滑动。而弹性装置7能够吸收部分冲力，起到缓冲支撑作用。而活塞杆61可以沿着筒体62滑动。防护层一4和防护层二5可以增加防护壳3的结构强度，并且通过橡胶制的防护层二5来提供缓冲防护。而石棉制的防护层一4可以隔热并增加缓冲隔离。为轮体1的两侧提供了很好的防护。
