[0002] In existing mechanical transmission mechanisms, power output and power reception are generally single-point transmission in a single direction, that is, single input and single output. In order to improve work efficiency and reduce costs, a single input and multiple shaft output are often required, which often results in a complex equipment structure and a large volume, high manufacturing cost, and is difficult to achieve in most cases due to space constraints, and the stability of the transmission mechanism is relatively poor. Therefore, it is urgent to provide a multi-axis synchronous transmission mechanism with a single input and multiple shaft output and a stable and compact structure to effectively improve transmission efficiency and reduce manufacturing costs.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figures 1 to 5 As shown, a multi-axis synchronous transmission mechanism includes a fixed seat 1, a driving shaft 2, a housing 3, and at least two transmission shafts 6. The driving shaft is rotatably connected to the fixed seat through a bearing, and its output end passes through the fixed seat and is connected to a main gear plate 4. The end surface of the main gear plate is provided with a main tooth pattern 401. The fixed seat is provided with an auxiliary gear plate 5 that is parallel to the main gear plate and located on the same central axis. The side end surface of the auxiliary gear plate close to the main gear plate is provided with auxiliary tooth patterns 501 in the opposite direction to the main tooth patterns. The input end of the driving shaft is externally connected to a motor to drive it to rotate, which can drive the main gear plate to rotate, and the auxiliary gear plate, The fixed seat is stationary relative to the main gear disc. At least two transmission shafts 6 are located between the main gear disc and the auxiliary gear disc and are distributed in a circular array. Each transmission shaft is arranged along the radial direction of the main gear disc and is provided with transmission teeth 601 respectively meshing with the main teeth and the auxiliary teeth. The housing is arranged outside the main gear disc and the auxiliary gear disc and is rotatably connected to the output end of the drive shaft through a bearing. One end of each transmission shaft passes through the housing and is rotatably connected to the housing through a bearing, that is, one end of each transmission shaft is connected to the main gear disc and the auxiliary gear disc through the transmission teeth, and the other end is rotatably connected to the housing. When the main gear disc drives each transmission shaft to perform circular motion along its end face, the housing rotates synchronously therewith. Due to the limitation of the auxiliary gear disc, each transmission shaft needs to rotate synchronously along its own central axis, which effectively reduces the radial runout of the transmission shaft, makes the transmission mechanism run more smoothly, and greatly reduces the probability of damage to each component during operation. Finally, each transmission shaft rotates along the central axis of the two gear discs and rotates along its own central axis in a three-dimensional multi-axis output.

[0025] like Figure 5As shown, a protective cover plate 7 is provided on the outer periphery of the fixed seat, a gap 8 is left between the inner side of the protective cover plate and the fixed seat, and the outer side thereof is connected to the shell, the protective cover plate and the shell are detachably connected, the outer diameter of the protective cover plate is greater than or equal to the outer diameters of the two toothed discs, which is convenient for disassembly and assembly of the shell without affecting the rotation of the shell along the central axis of the fixed seat, and is also convenient for replacement of the seal 9 installed in the gap, the seal can prevent external dust from entering the interior of the shell and affecting the movement stability between the main toothed disc, the auxiliary toothed disc and the transmission shafts, and there is a rotating sliding seal between the protective cover plate and the seal.

[0026] The working principle of the utility model is as follows:

[0027] like Figures 1 to 5 As shown, in the accompanying drawings of this embodiment, five transmission shafts are taken as an example. A single motor is externally connected to the input end of the drive shaft 2 to control the rotation of the drive shaft 2, and the drive shaft 2 drives the main gear plate 4 to rotate. Since the main gear plate 4 is meshed with each transmission shaft 6, each transmission shaft 6 and the housing 3 rotate synchronously with the main gear plate 4. Since the auxiliary gear plate 5 is also meshed with each transmission shaft 6, under the limitation of the auxiliary gear plate 5, each transmission shaft 6 will rotate along its own central axis at the same time. The overall structure is stable and compact, and the volume is relatively small, which effectively reduces the manufacturing cost, and at the same time reduces the radial runout of the transmission shaft 6, and the transmission operation is smoother, and finally a single input and a three-dimensional multi-axis output are achieved, which improves the transmission efficiency and has strong practicality.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
