具体实施方式
以下将以图式揭露本发明的多个实施方式，为明确说明起见，许多实务上的细节将在以下叙述中一并说明。然而，应了解到，这些实务上的细节不应用以限制本发明。也就是说，在本发明的部分实施方式中，这些实务上的细节是非必要的。此外，为简化图式起见，一些习知惯用的结构与组件在图式中将以简单的示意的方式绘示之。
需要说明，本发明实施例中所有方向性指示(诸如上、下、左、右、前、后……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指 示也相应地随之改变。
另外，在本发明中如涉及“第一”、“第二”等的描述仅用于描述目的，并非特别指称次序或顺位的意思，亦非用以限定本发明，其仅仅是为了区别以相同技术用语描述的组件或操作而已，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本发明要求的保护范围之内。
为能进一步了解本发明的内容、特点及功效，兹例举以下实施例，并配合附图详细说明如下：
请参照图1及图2，图1为本发明实施例中无间隙齿轮传动机构2的结构示意图；图2为本发明实施例中无间隙齿轮传动机构2的另一结构示意图。如图所示，本申请的无间隙齿轮传动机构2包括输出齿轮21、两个中间齿轮22及两个输入齿轮23。两个中间齿轮22与输出齿轮21同时啮合，即两个中间齿轮22的轮齿分别抵接输出齿轮21的异侧齿面，具体地，两个中间齿轮22均为双联齿轮。两个输入齿轮23的旋向相同，两个输入齿轮23错位设置，即两个输入齿轮23的轮齿的投影不重合，两个输入齿轮23分别与两个中间齿轮22啮合。
具体应用时，外部驱动件驱动两个输入齿轮23转动，两个输入齿轮23的齿数、模数等各项参数均相同，由于两个输入齿轮23错位设置，从而使得分别与两个输入齿轮23啮合的两个中间齿轮22的轮齿同时与输出齿轮21的轮齿接触，使得二者之间不存在侧隙，进行无侧隙齿轮传动，从而提高传动精度。
优选地，两个中间齿轮22及两个输入齿轮23均为斜齿轮。斜齿轮的啮合性能好，重合度大，结构紧凑，可保证传动的平稳性。
优选地，两个输入齿轮23之间设有弹性件24，弹性件24的两端分别抵接两个输入齿轮23，具体地，弹性件24为弹簧。由于弹性件24具有弹力，因此，在齿轮传动过程中，两个输入齿轮23在弹力的作用下可进行轴向移动，又由于两个中间齿轮22及两个输入齿轮23均为斜齿轮，两个输入齿轮23进行轴向移动时，中间齿轮22的轮齿与输入齿轮23的轮齿呈现交错啮合的状态，也就是说，中间齿轮22的轮齿与输入齿轮23的轮齿一高一低，中间齿轮22的齿面与输入齿轮23的齿面接触，以实现自动调节齿侧间隙。
本实施例的无间隙齿轮传动机构2可用于减速电机，下面，具体说明其用于减速电机的结构及工作原理。
再一并参照图3、图4及图5，图3为本发明实施例中减速电机的结构示意图；图4为本发明实施例中减速电机的另一结构示意图；图5为本发明实施例中减速电机与输入齿轮23配合的结构示意图。如图所示，减速电机包括机壳1、无间隙齿轮传动机构2及驱动电机3。无间隙齿轮传动机构2设置于机壳1内。驱动电机3通过螺栓螺设于机壳1，驱动电机3的输出端贯穿机壳1侧壁连接机壳1内的无间隙齿轮传动机构2。
具体应用时，输出齿轮21设置于机壳1内，输出齿轮21上螺设有输出轴211，输出齿轮21与输出轴211同轴心，输出轴211贯穿机壳1侧壁。两个中间齿轮22通过转动轴221转动设置于机壳1内，转动轴221的两端分别套设有波形垫片222，波形垫片222具备良好的弹性及抗冲击等性能，在两个中间齿轮22转动过程中起到防止松动和缓冲的作用。两个输入齿轮23及弹性件24均套设于驱动电机3的输出轴上，驱动电机3的输出轴远离驱动电机3的一端通过螺栓连接有垫片25，驱动电机3的输出轴靠近驱动电机3的一端套设有卡簧26，通过垫片25及卡簧26限制两个输入齿轮23的轴向移动距离，使其只能在垫片25及卡簧26之间进行移动。
具体应用时，驱动电机产生驱动力驱动两个输入齿轮23转动，两个输入齿轮23分别带动两个中间齿轮22转动，两个中间齿轮22同时带动输出齿轮21转动，输出齿轮21带动输出轴211转动，将力传递给与输出轴211连接的零部件。
优选地，驱动电机3的输出轴还套设有O型圈27，O型圈27位于两个输入齿轮23与垫片25及卡簧26之间，也就是说，垫片25与一个输入齿轮23之间有O型圈27，卡簧26与另一个输入齿轮23之间也有O型圈27，通过O型圈27以实现动态密封。
具体应用时，减速电机还包括传感器4，传感器4通过螺栓螺设于机壳1，具体地，传感器4为槽型光电开关，输出轴211上螺设有感应片212，输出齿轮21转动时带动输出轴211转动，输出轴211带动感应片212转动，感应片212转动过程中经过槽型光电开关的槽时，红外线发射管、感应片212及红外线接收管三者在一条直线上，感应片212遮挡红外线发射管发射的红外线使得红外线接收管接收不到光线，槽型光电开关将此状态的信号反馈给控制系统，以便于使用者了解无间隙齿轮传动机构2的工作状态。
综上所述，在本发明一或多个实施方式中，本发明的无间隙齿轮传动机构通过将两个输入齿轮错位设置，使得传动齿组转动过程中两个中间齿轮的轮齿始终与输出齿轮的两侧齿面抵接，从而消除传动间隙，提高传动精度。
上所述仅为本发明的实施方式而已，并不用于限制本发明。对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理在内所作的任何修改、等同替换、改进等，均应包括在本发明的权利要求范围之内。
