The present invention relates to a high fault-tolerant coupling transmission mechanism with a positive guiding function. The connection interface has a rotary taper, the connection shaft on one side of the convex cone has several key grooves along the circumferential direction of the convex cone surface, the connection shaft on one side of the concave cone has two floating blocks inside, and the outer part of the floating block is connected with the connection shaft to enable itself to move along the two axes of the connection shaft. The concave cone with sliding direction and matching convex cone is on the inside. The circumferential distribution of the concave cone is one-to-one key groove. Springs are installed between the bottom side of the floating block and the inner wall of the connecting shaft. When the connecting shaft is inserted into the floating block, the matching convex cone and the concave cone guide the two connecting axes to compress the spring in coaxial direction gradually, and the two connecting axes are in phase. When rotating, the key is pressed into the keyway under the spring pressure to transfer the torque stably; when the key and keyway cooperate, there is a certain gap, which ensures that the two coupling shafts can transfer the torque when there is a certain angle between them. The mechanism has high fault tolerance, positive guiding function, good stability and convenient disassembly and assembly.

具备导正功能的高容错性联接传动机构
本专利技术属于机械联接领域,具体涉及一种具备导正功能的高容错性联接传动机构。
技术介绍
键联接是机械联接中用于传递扭矩的联接方法,现有的键联接一般安装后很少拆装。对于两轴有轴向运动的键联接,目前一般采用滑键联接,或者轴与轴套中间穿插一根轴,使轴移出的过程中不发生转动或者其他方向的运动,而对于轴与轴套会分离、没有中间轴固定、键位要对齐的要求,现有的联接方式很难达到。因此,需要一种能导正、能传递扭矩、稳定性好、拆装方便的联接传动机构。
技术实现思路
本专利技术的目的是提供一种具备导正功能的高容错性联接传动机构,该机构具备高容错性,具备导正功能,稳定性好,拆装方便。本专利技术所采用的技术方案是:一种具备导正功能的高容错性联接传动机构,联接界面存在回转锥度,凸锥一侧的联接轴一沿凸锥面周向分布有若干键槽,凹锥一侧的联接轴二内部设有浮动块,浮动块外侧与联接轴二联接使得自身能沿联接轴二轴向滑动、内侧为与凸锥面配合的凹锥面,凹锥面周向分布有与键槽一一对应的键,浮动块底侧与联接轴二内壁间装有弹簧;联接轴一插入浮动块时,配合的凸锥面和凹锥面导引两个联接 ...
