Abstract
A ball bearing coupling comprises a main driving part, ball bearing and a slave moving part. The convex part of two ball bearing in between the main driving part or the slave moving part are asymmetry to have a one-way torque transmission or a different maximum torque in two ways transmission. As showed in the picture, anti-clockwise moving is the main torque transmission direction; clockwise moving is an assistant torque transmission direction. The one-way torque transmission or a different maximum torque in two ways transmission can increase the loading ability.
Description
The present invention relates to a kind of ball coupling.
Existing ball coupling all is to be used for positive and negative both direction can both transmit onesize moment of torsion, in machinery, has plenty of unidirectional delivery, the Maximum Torque of having plenty of positive and negative both direction transmission is different, and the resource of ball coupling just can not be fully utilized in this case.
The objective of the invention is to design Maximum Torque that a kind of unidirectional delivery moment of torsion or both direction the transmit ball coupling when different.Accompanying drawing is a structural representation of the present invention.
A kind of ball coupling, form by driving link (1), ball (2) and driven member (3), the outer surface of the internal surface of driving link (1) and driven member (3) has the convex-concave of picture zigzag fashion partly to contact with ball (2), and the protuberance between driving link (1) or driven member (3) and adjacent two balls is asymmetric.Can design Maximum Torque that a kind of unidirectional delivery moment of torsion or both direction the transmit ball coupling when different like this.Driving link (1) is when turning to transmitting torque counterclockwise as shown in the figure, and driving link (1) is longer with the interactional arc length of ball (2), and driven member (3) is also longer with the interactional arc length of ball (2).Driving link (1) is when turning to transmitting torque clockwise, and driving link (1) is shorter with the interactional arc length of ball (2), and driven member (3) is also shorter with the interactional arc length of ball (2).Be the main direction of transfer of moment of torsion so driving link (1) turns to counterclockwise, clockwise direction is the less important direction of transfer of moment of torsion.The difference of the torque condition of being transmitted according to the positive and negative both direction of machinery, the convex-concave shape partly that can change driving link (1) and driven member (3) is carried out resource allocation, is not optimized not have meter, and the bearing capacity of ball coupling is greatly improved.
Improved bearing capacity greatly under the situation of the present invention when the Maximum Torque of unidirectional delivery moment of torsion or both direction transmission is different, great economic value and market have widely been arranged.
Claims (3)
1, a kind of ball coupling is made up of driving link (1), ball (2) and driven member (3), and the outer surface that it is characterized in that the internal surface of driving link (1) and driven member (3) has the convex-concave as zigzag fashion partly to have arc groove to contact with ball (2).
2, a kind of ball coupling as claimed in claim 1 is characterized in that the internal surface of driving link (1) and the outer surface of driven member (3) and the protuberance between adjacent two balls are asymmetric.
3, as claim 1,2 described a kind of ball couplings, it is characterized in that comparing when positive and negative two directions are rotated, the outer surface and the contacted arc length of ball of the internal surface of driving link (1) and driven member (3) they are unequal.
