Description

Technical Field

[0001] The invention relates to the technical field of gear meshing, and in particular to an automatic meshing structure. Background Art

[0002] Meshing refers to a transmission relationship between two mechanical parts, which is called meshing transmission; gear transmission is the most typical meshing transmission and the most widely used form of transmission; gear meshing transmission has the characteristics of wide adaptability, high transmission efficiency, long service life, smooth transmission, high reliability, and the ability to achieve two-axis transmission for various position requirements. It is widely used in mechanical transmission, especially in outdoor advertising equipment.

[0003] During the gear transmission process, when the driving shaft and the driven shaft move, they usually wear out due to long-term rotation, and gaps are formed between the gears. On the one hand, this makes the structure between the driving shaft and the driven shaft unstable. On the other hand, when the driving shaft drives the driven shaft, more energy will be lost. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention aims to solve the problem of gaps formed due to wear between gears when a driving shaft drives a driven shaft in the prior art.

[0005] The object of the present invention is to provide an automatic engagement structure to solve the related problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An automatic meshing structure, comprising: an active bearing, an active bearing fixing plate, a driven bearing, a driven bearing fixing plate, and a swing arm connecting structure between the active bearing fixing plate and the driven bearing fixing plate;

[0008] The active bearing is fixed on the active bearing fixing plate, and the driven bearing is fixed on the driven bearing fixing plate;

[0009] The swing arm connection structure connects the active bearing fixing plate and the driven bearing fixing plate through an elastic connection structure.

[0010] Among them, the swing arm connection structure is a symmetrical "human" shaped structure; the "human" shaped swing arm connection structure is also connected to the active bearing fixing plate and the driven bearing fixing plate through a fixed shaft; the fixed shaft and the elastic connection structure are respectively located at both ends of the "human" shaped swing arm connection structure.

[0011] Preferably, there are no less than two elastic connection structures; the two elastic connection structures are symmetrical, and the two elastic connection structures are respectively located at two ends of the "human" shaped swing arm connection structure.

[0012] The elastic connection structure includes: a spring movable rod, a spring, a locking nut, and a spring rod sleeve;

[0013] The spring movable rod passes through the locking nut, the spring, the active bearing fixing plate, and the driven bearing fixing plate in sequence, and is fixed on the driven bearing fixing plate. The spring is limited between the active bearing fixing plate and the locking nut. The pressure of the spring makes the active bearing fixing plate and the driven bearing fixing plate always coincide with each other.

[0014] The spring rod is sleeved on the outer surface of the spring movable rod and wraps the spring, and the spring rod sleeve plays a protective role on the spring.

[0015] The present invention is characterized in that: one,

[0017] The swing arm connection structure between the active bearing fixing plate and the driven bearing fixing plate makes the active bearing fixing plate and the driven bearing fixing plate more stable, especially in large transmission structures, such as outdoor billboards, etc., the effect is obvious. two,

[0019] The active bearing is fixed on the active bearing fixing plate, and the driven bearing is fixed on the driven bearing fixing plate;

[0020] The swing arm connection structure connects the active bearing fixing plate and the driven bearing fixing plate through an elastic connection structure, so that there is an external pressure between the active bearing fixing plate and the driven bearing fixing plate, so that:

[0021] The active bearing and the driven bearing can mesh automatically. Even if there is wear between them during operation, they can mesh automatically under the action of external pressure.

[0022] 3. The first option

[0023] The "human" shaped swing arm connection structure is also connected to the driven bearing fixing plate through a fixed shaft; the fixed shaft and the elastic connection structure are respectively located at two ends of the "human" shaped swing arm connection structure.

[0024] Compared with the second solution described below, there is one less elastic connection structure, the structure is relatively simple and the cost is lower;

[0025] 4. The second option

[0026] The two elastic connection structures are respectively located at the two ends of the "human" shaped swing arm connection structure. The symmetrical elastic connection structure is more stable and the rotation between the gears is smoother.

[0027] 5. The end of the "human" shaped swing arm connecting structure is in a horizontal state and is perpendicular to the elastic connecting structure, so that the pressure direction of the elastic connecting structure is perpendicular to the "human" shaped swing arm connecting structure; the pressure is not dispersed and is in the most labor-saving state.

[0028] 6. The elastic connection structure includes: a spring movable rod, a spring, a locking nut, and a spring rod sleeve;

[0029] The structure is simple and practical. BRIEF DESCRIPTION OF THE DRAWINGS
