Embodiment Construction

[0021] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] A double universal joint composed of double universal flexible joints is composed of flexible rotating pair 1, flexible rotating pair 2, flexible rotating pair 3, flexible rotating pair 4, 6, connecting plate 1, connecting plate 2, 4, connecting Plate III consists of 7. Flexible rotary pair one 2, flexible rotary pair two 3, flexible rotary pair three 5, flexible rotary pair four 6 are to have circular arc-shaped notch cylinder. Flexible rotary pair 1 2 and flexible rotary pair 2 3 are axially vertically connected, and flexible rotary pair 3 5 and flexible rotary pair 4 6 are axially vertically connected. The connecting plate one 1 is connected with the flexible rotating pair one 2 and is tangent. The second flexible revolving pair 3 and the third flexible revolving pair 5 are connected through the second connecting plate 4, and the s...

Abstract

The invention relates to a double universal joint consisting of flexible knuckles, which can be used as various types of joints of robots and multi-dimensional actuating vibration tables and belongs to the application fields of the robots and the multi-dimensional actuating vibration tables. The double universal joint consists of four cylindrical flexible revolute pairs and three steel plate connecting plates. The cylindrical flexible revolute pairs are made of a flexible material namely spring steel and are provided with arc-shaped gaps, and the sizes of the arc-shaped gaps are between 30 and 70 degrees. A cylindrical cylinder is equivalent to one flexible revolute pair, and two cylindrical flexible revolute pairs of which the axial lines are vertical to each other are combined together by welding to form a single universal joint. The double universal joint uses a flexible kinematic pair to replace a common universal joint so as to form a brand new flexible kinematic pair. The flexible kinematic pair achieves expected motion outputs through the elastic deformation of a material, has a simple structure, low manufacturing cost, flexible rotation and no lubrication, and can avoid motion distortions caused by universal joint gaps.

Description

technical field [0001] The patent of the present invention relates to a double universal joint composed of flexible joints. The joint is a flexible joint, which can be used as various joints of robots and multi-dimensional vibration excitation tables, and belongs to the application fields of robots and multi-dimensional vibration excitation tables. Background technique [0002] The particularity of the universal joint structure allows it to be used for power transmission between two shafts whose relative positions are constantly changing during the working process. This feature is different from gear transmission, belt transmission and chain transmission in conventional mechanical transmission, so universal joints are widely used in modern automobiles, wheeled construction machinery and agricultural vehicles above medium-sized, and universal joints are also widely used in multi-dimensional Exciting table test. The new flexible double universal joint joint proposed in this p...
