Description
技术领域:Technical field:
本发明涉及单向旋转机构领域,具体涉及一种单向旋转机构实现反向无障碍转动的方法。The invention relates to the field of one-way rotating mechanisms, in particular to a method for realizing reverse barrier-free rotation of a one-way rotating mechanism.
背景技术:Background technique:
目前常规单向旋转传动机构,大部分都是两个旋转体同时单向旋转,其中一个旋转体旋转必定带动另一个旋转体向相反的方向旋转,但是如果需要其中一个旋转体反方向转动时,由于另一个旋转体反向旋转设有制动装置,因此就会成为其反向旋转的障碍,而使得此动作无法实现。在实际应用中,例如在设计翻转平台时,其中翻转平台相当于一个旋转体,一端通过转轴和固定铰支座连接,并为翻转平台一端的提供支撑,而另一端就需要可旋转的支座来提供支撑,如果采用固定支座,为了能够实现对翻转平台另一端的支撑,固定支撑座就必须位于翻转平台的旋转半径以内,在翻转平台翻转的过程中,固定支座就会与翻转平台发生干涉,阻碍翻转平台的翻转,导致翻转平台无法绕过固定支座而继续翻转。而选择翻转支座时,由于翻转支座为了能够为平台提供支撑,所以翻转座应为单向旋转,另一个方向需有制动装置,才能为翻转平台提供支撑,即翻转座只能作与翻转平台旋转方向相反的单向旋转动作。当翻转平台需要反向转动落下时,由于翻转座反向转动设有制动装置,因此给翻转平台的反向旋转带来了阻碍,翻转平台可以推开翻转座而向上旋转,但当翻转平台需要落下时,由于翻转座不能实现旋转避让,使得翻转平台无法向反方向旋转来实现落下动作。At present, most of the conventional one-way rotary transmission mechanisms are two rotating bodies that rotate in one direction at the same time. The rotation of one rotating body must drive the other rotating body to rotate in the opposite direction, but if one of the rotating bodies is required to rotate in the opposite direction, Since the other rotating body is provided with a braking device for reverse rotation, it will become an obstacle to its reverse rotation, making this action impossible. In practical applications, for example, when designing a flipping platform, the flipping platform is equivalent to a rotating body, one end is connected by a rotating shaft and a fixed hinge support, and provides support for one end of the flipping platform, while the other end needs a rotatable support To provide support, if a fixed support is used, in order to support the other end of the flipping platform, the fixed support must be located within the rotation radius of the flipping platform. During the flipping process of the flipping platform, the fixed support will Interference occurs, which hinders the turning of the turning platform, so that the turning platform cannot bypass the fixed support and continue to turn. When choosing the flipping support, because the flipping support can provide support for the platform, the flipping base should be one-way rotation, and a braking device is required in the other direction to provide support for the flipping platform, that is, the flipping base can only be used with A one-way rotation action in which the platform rotates in the opposite direction. When the flipping platform needs to rotate in the reverse direction and fall down, the reverse rotation of the flipping seat is provided with a braking device, which hinders the reverse rotation of the flipping platform. When it needs to be dropped, since the turning seat cannot realize the rotation avoidance, the turning platform cannot rotate in the opposite direction to realize the falling action.

实施例1:Example 1:
一种单向旋转机构反向无障碍转动装置,其组成包括:旋转体A1,旋转体B2,所述的旋转体A、所述的旋转体B中心均通过转轴和固定铰支座连接,所述的旋转体A为单向转动,反方向旋转设有制动自锁装置,所述的旋转体B可实现不受外部条件限制时为双向转动,所述的旋转体B连接有占位装置3。A reverse barrier-free rotating device of a one-way rotating mechanism, which is composed of: a rotating body A1, a rotating body B2, the centers of the rotating body A and the rotating body B are connected by a rotating shaft and a fixed hinge support, so The rotating body A described is unidirectional rotation, and a braking self-locking device is provided for rotation in the opposite direction. The rotating body B can realize bidirectional rotation when it is not restricted by external conditions, and the rotating body B is connected with a space-occupying device. 3.
实施例2:Example 2:
一种利用实施例1所述的单向旋转机构实现反向无障碍转动的方法,该方法包括如下步骤:A method for realizing reverse barrier-free rotation using the one-way rotating mechanism described in
(1)旋转体A和旋转体B之间作单向旋转,其中旋转体A为单向转动,反方向设有制动装置,旋转体B在不受外部条件限制时为双向转动;(1) One-way rotation is performed between the rotating body A and the rotating body B, wherein the rotating body A is a one-way rotation, a braking device is provided in the opposite direction, and the rotating body B is a two-way rotation when it is not restricted by external conditions;
(2)所述的旋转体A在一定角度范围内可通过自身反转力自动反向转动到前一个制动位置,旋转体A转动超过设置的制动角度时,触发反向制动,此时旋转体A不能通过自身反转力进行反方向转动;(2) The rotating body A can automatically reversely rotate to the previous braking position through its own reversal force within a certain angle range. When the rotating body A rotates beyond the set braking angle, the reverse braking is triggered. When the rotating body A cannot rotate in the opposite direction through its own reversal force;
(3)所述的旋转体B需要反向转动时,旋转体B上的占位装置从旋转体A的旋转半径外逐渐占满旋转体B前端,并带动旋转体A旋转,使旋转体A转动一定角度,旋转角度小于制动角度,为旋转体B的反向转动提供旋转空间,在旋转体B反方向转动过程中,占位装置始终顶靠在旋转体A上,旋转体A在自身反转力作用下随着旋转体B的转动而逐渐转动,当旋转体B反向转动到旋转体A的制动位置时,旋转体A停止转动;(3) When the rotating body B needs to rotate in the reverse direction, the space-occupying device on the rotating body B gradually fills the front end of the rotating body B from outside the rotation radius of the rotating body A, and drives the rotating body A to rotate, so that the rotating body A is rotated. Rotate a certain angle, and the rotation angle is smaller than the braking angle, which provides a rotating space for the reverse rotation of the rotating body B. During the reverse rotation of the rotating body B, the space-occupying device always abuts on the rotating body A, and the rotating body A is on itself. Under the action of the reverse force, it gradually rotates with the rotation of the rotating body B. When the rotating body B reversely rotates to the braking position of the rotating body A, the rotating body A stops rotating;
(4)所述的旋转体A到达制动位置时,旋转体A可以对旋转体B提供支撑。(4) When the rotating body A reaches the braking position, the rotating body A can provide support for the rotating body B.
旋转体A为单向连续旋转,在一定角度范围内(不超过制动角度时)可通过自身反转力进行反方向转动,即在两个制动范围区间内,旋转体A可自动反方向回转至其前一个制动位置。当旋转体A旋转角度超过设置的制动角度时,旋转体A进入下一个制动区间,此种情况下旋转体A和旋转体B只能沿一个单一方向作旋转运动,使得旋转体B无法进行反向转动。该方法是在旋转体B的前端用占位装置从旋转体A的旋转半径外逐渐占满旋转体B的前端,来使旋转体A从制动位置转动一定角度,从而为旋转体B的反向转动提供足够的旋转空间,实现旋转体B的反向无障碍转动。The rotating body A rotates continuously in one direction. Within a certain angle range (not exceeding the braking angle), it can rotate in the opposite direction through its own reversal force, that is, within the two braking ranges, the rotating body A can automatically reverse the direction. Swing back to its previous braking position. When the rotation angle of the rotating body A exceeds the set braking angle, the rotating body A enters the next braking section. In this case, the rotating body A and the rotating body B can only rotate in a single direction, so that the rotating body B cannot Perform the reverse rotation. In this method, the front end of the rotary body B is gradually filled with the front end of the rotary body B from the outside of the rotation radius of the rotary body B with a space-occupying device, so that the rotary body A is rotated from the braking position by a certain angle, so as to be a countermeasure for the rotary body B. Provide enough rotation space for the rotation to realize the unobstructed reverse rotation of the rotating body B.
当旋转体B需要反向旋转时,首先将旋转体B按原旋转方向转动一定角度,与旋转体A形成一定倾斜角度,但未到达制动位置,此时占位装置从旋转体A的最大回转半径外逐渐向旋转体B端部靠拢,靠拢的过程中占位装置将旋转体A逆时针拨动,带动旋转体A旋转,为旋转体B的反向转动提供空间,从而消除旋转体A对旋转体B反向转动的阻碍,实现旋转体B的反方向无障碍转动。在旋转体B反方向转动的过程中,旋转体A在自身反转力的作用下跟随旋转体B一起回转,回转到前一个制动位置时旋转体A不在转动。When the rotating body B needs to rotate in the reverse direction, firstly rotate the rotating body B by a certain angle according to the original rotation direction to form a certain inclination angle with the rotating body A, but it does not reach the braking position. The outside of the turning radius gradually moves closer to the end of the rotating body B. During the approaching process, the space-occupying device turns the rotating body A counterclockwise to drive the rotating body A to rotate, providing space for the reverse rotation of the rotating body B, thereby eliminating the rotating body A. Obstructing the reverse rotation of the rotating body B, realizing the unobstructed rotation of the rotating body B in the opposite direction. When the rotating body B rotates in the opposite direction, the rotating body A rotates along with the rotating body B under the action of its own reversal force, and the rotating body A does not rotate when it returns to the previous braking position.
实施例3:Example 3:
根据实施例1或2所述的单向旋转机构实现反向无障碍转动的方法的具体实施步骤如下:The specific implementation steps of the method for realizing the reverse barrier-free rotation of the one-way rotating mechanism according to
暂定旋转体B为动力输入端时,结合说明书附图1和2,通过旋转体B旋转带动旋转体A进行旋转,由于旋转体A为单向旋转,反向旋转时有制动功能,所以当旋转体B反向转动时,就会遇到旋转体A的阻碍,而无法继续转动,此时旋转体A对旋转体B可以起到支撑作用。当旋转体B需要继续反向转动时,需要先将旋转体B按原方向旋转一定角度,同时通过占位装置,从旋转体A的最大回转直径外逐渐向旋转体B的齿端部靠拢,逐渐将旋转体B的端部填满,占位装置靠拢的过程中带动旋转体A旋转,旋转体A的旋转角度小于制动角度,当占位装置将旋转体B的前端完全占满时,刚好旋转体A对旋转体B的反方向转动没有阻碍。占位装置到达位置后,旋转体B即可躲避旋转体A的阻碍而进行反向旋转,此时旋转体A在自身反转力的作用下,自动跟随旋转体B进行相应转动,直至到达其制动位置停止,从而实现旋转体B的反向转动。When the rotating body B is tentatively set as the power input end, the rotating body B is rotated to drive the rotating body A to rotate. Since the rotating body A rotates in one direction and has a braking function when it rotates in the opposite direction, it has a braking function. When the rotating body B rotates in the reverse direction, it will encounter the obstacle of the rotating body A and cannot continue to rotate. At this time, the rotating body A can play a supporting role for the rotating body B. When the rotating body B needs to continue to rotate in the reverse direction, it is necessary to rotate the rotating body B by a certain angle in the original direction. Gradually fill up the end of the rotating body B, and drive the rotating body A to rotate during the process of the space-occupying device moving closer. The rotation angle of the rotating body A is smaller than the braking angle. When the space-occupying device completely occupies the front end of the rotating body B, The rotating body A just does not hinder the reverse rotation of the rotating body B. After the occupying device reaches the position, the rotating body B can avoid the obstruction of the rotating body A and rotate in the reverse direction. At this time, the rotating body A automatically follows the rotating body B to rotate correspondingly under the action of its own reversal force until it reaches its position. The braking position is stopped, so that the reverse rotation of the rotating body B is realized.
