Description

Technical Field

[0001] The invention discloses a rotating structure with adjustable transmission direction and a transmission direction adjusting method, belonging to the technical field of mechanical transmission. Background Art

[0002] The transmission structure refers to the structure for power transmission between machines, which transmits mechanical power to terminal equipment through an intermediate medium. It can be divided into three categories: mechanical transmission, fluid transmission and electric transmission. Mechanical transmission uses machine parts to directly realize transmission; fluid transmission uses liquid or gas as the working medium, which can be divided into hydraulic transmission relying on the static pressure of liquid, hydraulic transmission relying on the dynamic action of liquid, and pneumatic transmission relying on the pressure of gas; electric transmission uses electric motors to convert electrical energy into mechanical energy to drive the working part of the machine.

[0003] Among these transmission modes, mechanical transmission can adapt to various power and motion requirements and is the most widely used; fluid transmission is highly flexible and the transmission direction can be flexibly changed, but the small transmission power range and short transmission distance limit the application of fluid transmission in many fields; electric transmission has a large power range and is easy to realize automatic control and remote control, but the transmission direction cannot be flexibly changed.

[0004] It can be seen that if we want to have a wide transmission power range and the transmission direction can be flexibly changed, and at the same time require a wide range of applications, we also need to work on the direction of mechanical transmission.

[0005] Among many transmission modes, rotational transmission is the most widely used. For example, the suspension structure of a front-wheel drive vehicle still requires power when the front wheels of the vehicle deflect. Therefore, a rotational structure that can adjust the transmission direction is naturally indispensable. Some existing technologies have also emerged with structures with the same function.

[0006] In response to the problem that the existing transmission shaft constant velocity universal joint cannot adjust its own length according to the distance between the two mounting axes, the utility model patent "Transmission shaft constant velocity universal joint connection structure" with application number 202221647172.4 provides a solution. The structure includes a connecting rod, and mounting plates are respectively installed at both ends of the connecting rod through a cross shaft. The connecting rod includes a barrel, a cylinder, a screw assembly and a drive assembly. The cylinder is plugged into the barrel, and the inner cavity of the barrel is equipped with a screw assembly that can drive the cylinder to move outward relative to the barrel to change the length of the universal joint. The inner cavity of the barrel is equipped with a drive assembly that can drive the screw assembly to operate and position. The rotation of the screw can drive the cylinder to move in a linear direction, thereby changing the length of the entire universal joint. The operation is convenient and simple. A hexagonal groove is provided on the end of the rotating rod located at the outer end of the barrel, and the rotating rod can be squeezed and rotated by cooperating with the hexagonal groove through the hexagonal wrench, so as to facilitate the adjustment of the length of the universal joint.

[0007] However, this structure cannot be adjusted dynamically and needs to stop the transmission and then change the transmission position before continuing the transmission work. This affects the transmission efficiency and increases the difficulty of adjusting the transmission direction. Summary of the invention

[0008] In order to address the deficiencies in the prior art, the present application designs a rotation structure with adjustable transmission direction and a transmission direction adjustment method.

6. A method for adjusting the transmission direction of a rotating structure, implemented on the rotating structure with adjustable transmission direction as claimed in claim 3, characterized in that: A universal joint (3) is used to adjust the transmission direction. When the input shaft (1) rotates, the first connecting plate (4) is driven to rotate, and the transmission joint (6) is driven to rotate at the same time, so that the second connecting plate (5) rotates synchronously and the output shaft (2) is driven to rotate synchronously, so that the output shaft (2) rotates stably inside the output bearing (30). When the transmission direction needs to be adjusted, the first electric push rod (18) is extended to push the movable plate (19) to slide on the surface of the spherical shaft (10), thereby driving the connecting rod (21) to move, which drives the end head (22) to rotate around the center of the spherical shaft (10), and the first ball (23) at the end head (22) drives the movable ring (24) to rotate inside the spherical shaft (10), thereby driving the adjustment plate (27) to rotate through the fixed rod (26), and while driving the output bearing (30) to rotate, the second electric push rod (21) drives the output bearing (30) to rotate. The extension and retraction of the movable push rod (31) drives the output bearing (30) to move inside the adjustment plate (27), and drives the slider (29) to move inside the slide groove (28). At this time, the output bearing (30) moves on the surface of the output shaft (2), thereby achieving the deflection of the output shaft (2). The output bearing (30) is adjusted in angle by the ends (22) on both sides of the movable ring (24). At the same time, the second electric push rod (31) is used to achieve stable limiting, and the output bearing (30) is limited, thereby achieving stable transmission and ensuring rotation stability. When the transmission angle needs to be adjusted, the motor (16) drives the gear (17) to rotate, and the transmission of the gear (17) and the gear ring (15) drives the fixed plate (14) and the sleeve shaft (9) to rotate, driving the adjustment plate (27) to adjust the angle first, and then the output shaft (2) is deflected along the length direction of the adjustment plate (27) by the extension and retraction of the first electric push rod (18), thereby achieving adjustment in any direction. Before and after the direction adjustment, the axial direction of the output shaft (2) is perpendicular to the plane where the output bearing (30) and the movable ring (24) are located. At this time, the output shaft (2) rotates inside the output bearing (30), and at the same time drives the movable ring (24) to rotate on the inner wall of the spherical shaft (10), and stable transmission is achieved through the second ball (25), thereby ensuring rotation stability.
