Description

一种减震用齿轮 技术领域
本发明涉及变速箱齿轮的技术领域，更具体地说涉及一种减震用齿轮。
背景技术
在各种传动形式中，齿轮传动在现代机械中应用最为广泛。在齿轮传送过程中会产生噪声，根据机理的不同，可将噪声分成加速度噪声和自鸣噪声两种，一般说来，自鸣噪声是闭式齿轮传动的主要声源；自鸣噪声是由齿轮体的振动通过传动轴引起支座振动，从而通过齿轮箱箱壁的振动而辐射出来，减少齿轮体的振动能有效降低齿轮产生的噪音；目前一些齿轮采用在轴孔的四周开设多个减震孔，在减震孔内安插橡胶缓冲件，通过减震孔和橡胶缓冲件来有效进行减震，但橡胶缓冲件会因振动影响脱离齿轮，而且橡胶缓冲件容易出现老化问题，需要可以进行更换，所以需要在齿轮上设计一种橡胶缓冲件不容易脱离并且方便更换的连接结构。
发明内容
本发明的目的就是针对现有技术之不足，而提供了一种减震用齿轮，其齿轮上的橡胶缓冲柱受端盖阻挡不容易脱离，而且端盖方便拆卸，便于橡胶缓冲柱的更换。
为实现上述目的，本发明采用的技术方案如下：
一种减震用齿轮，包括减震齿轮的主体，主体中部的两相对端面 上均成型有圆形的凸台，凸台上成型有中心孔，中心孔的内壁上成型有键槽,所述凸台四周的主体上成型有若干个减震孔，减震孔内插接有橡胶缓冲柱，主体两侧的凸台外壁上成型有螺纹，主体两侧的凸台上均螺接有端盖，橡胶缓冲柱的两端分别抵靠在主体两侧的端盖上，端盖上成型有定位销孔；所述主体一侧的橡胶缓冲柱上插接有定位销，定位销的两端分别插接在端盖的定位销孔内。
优选的，所述主体的中心轴线、凸台的中心轴线和中心孔的中心轴线均在同一直线上，减震孔至少设有三个，减震孔绕主体的中心轴线呈环形均匀分布。
优选的，所述的橡胶缓冲柱呈圆柱形，橡胶缓冲柱的外壁压靠在减震孔的内壁上；所述的定位销采用圆柱销，主体一侧的橡胶缓冲柱上成型有与定位销相对的插孔，插孔的孔径小小于定位销的直径。
优选的，所述主体两侧的端盖分别抵靠在主体的两侧端面上。
优选的，所述端盖的直径小于主体的直径，端盖的外壁上成型有若干防滑槽口。
优选的，所述端盖的厚度小于主体上凸台的长度。
本发明的有益效果在于：其上的橡胶缓冲柱受端盖阻挡不容易脱离，而且端盖方便拆卸，便于橡胶缓冲柱的更换。
