Abstract

为克服现有齿轮高副载荷能力较低的缺陷，本发明提供的齿轮低副，它以平面齿廓滑动传递动力，可以大幅提高齿轮传动副的单位尺度载荷能力。本发明包括有活齿轮与齿轮副，活齿轮与齿条副，活齿条与齿轮副。其活齿为两端有耳轴，齿廓为平面。

Description

齿轮低副
技术领域
本发明属于动力机械工程领域。
技术背景
现有齿轮齿廓都是曲面，其线接触高压强的动力传递方式，限制了其载荷能力在齿根弯曲应力许可值内进一步提高，不能满足某些工程需要。
发明内容
为满足小尺度大载荷齿轮动力传动的需要，本发明提供一种齿轮低副，它包括齿轮、齿轮副，齿轮、齿条副，齿条、齿轮副。齿轮、齿轮副包括两相互啮合的齿轮，其中一齿轮为活齿轮，该活齿轮的活齿两端有耳轴，齿廓为平面，另一齿轮的齿廓为平面；齿轮、齿条副包括相互啮合的齿轮、齿条，其中齿轮为活齿轮，其活齿两端有耳轴，齿廓为平面；齿条、齿轮副包括相互啮合的齿轮、齿条，其中齿条为活齿条，其活齿两端有耳轴，齿廓为平面。所述活齿轮的轮盘为沟槽轮盘，所述活齿条的条杆为沟槽条杆，它们的沟槽两壁均布活齿耳轴轴承。所述活齿在活齿轮盘或活齿条杆的沟槽中摆动迎合啮合齿，使两齿面贴合滑动传力，其活动齿耳轴抗剪许用应力远大于线接触许用应力，能显著提高齿轮承载能力，增大齿轮模数可以大幅缩小齿轮尺度。
附图说明
附图为齿条副示意图。
图中：1-活齿轮盘，2-活齿轮盘沟槽，3-活齿，4-齿条。
具体实施方式
齿轮、齿条副实施例。如附图所示，活齿轮盘1为两片相同的盘片同轴固接而成，其周边均布活齿耳轴轴承。活齿3在该两盘片接合过程中安放在该两盘片之间的沟槽2中。活齿3的齿形要求：活齿3的耳轴尽量置于其齿端顶部，齿条4的齿厚和齿高满足其与活齿轮啮合时，活齿3轴心低于啮合齿齿顶，以保障两齿齿面传力时良好贴合，合理传力。在活齿轮盘沟槽2中复有油毡作为活齿3的阻尼，减少过度摆动和振动噪声。活齿轮盘沟槽2的深度满足活齿在离心力作用下停在最佳初始啮合角度。
