Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a novel gear reduction mechanism 10 includes: an upper substrate 11, a lower substrate 12 and a speed reduction assembly 13; the reduction assembly 13 comprises: an input shaft 131, a first gear 132, a reduction shaft 133, a second gear 134, a third gear 135, a fourth gear 136, an output shaft 137, a fifth gear 138, and a sixth gear 139; both ends of the input shaft 131, the deceleration shaft 133 and the output shaft 137 are rotatably connected to the upper substrate 11 and the lower substrate 12, respectively; the first gear 132 is connected to the input shaft 131; the second gear 134 and the third gear 135 are connected to the reduction shaft 133; the fourth gear 136 is rotatably connected to the reduction shaft 133; the fifth gear 138 and the sixth gear 139 are connected to the output shaft 137; the first gear 132 is meshed with the second gear 134; the third gear 135 and the fourth gear 136 are engaged with a fifth gear 138 and a sixth gear 139, respectively.
Specifically, the input shaft 131 rotates to rotate the first gear 132. The first gear 132 drives the reduction shaft 133 to rotate through the second gear 134 to realize the first-stage reduction. When the reduction shaft 133 rotates, the third gear 135 and the fourth gear 136 connected to the reduction shaft 133 also rotate in synchronization with the reduction shaft 133. At this time, the fifth gear 138 is driven by the third gear 135, and two-stage reduction is achieved. When the fifth gear 138 rotates, the sixth gear 139 is driven to rotate by the output shaft 137. Since the sixth gear 139 is engaged with the fourth gear 136 and the fourth gear 136 can rotate relative to the reduction shaft 133, the sixth gear 139 drives the fourth gear 136 to rotate when rotating, and three-stage reduction is realized.
The novel gear reduction mechanism 10 can realize three-level speed reduction through the structure, and one-level speed reduction is added in the same space to obtain a higher speed reduction ratio. Meanwhile, the novel gear reduction mechanism 10 is simpler in structure, fewer in parts and lower in cost.
In one specific embodiment, the second gear 134 is located between the third gear 135 and the fourth gear 136. The arrangement is such that the first gear 132 and the second gear 134 are located in the middle of the input shaft 131 and the reduction shaft 133, respectively, ensuring that the centre of gravity of the mechanism is stable.
As a specific embodiment, the first gear 132 is keyed to the input shaft 131. The second gear 134 and the third gear 135 are connected to the reduction shaft 133 by keys. The fifth gear 138 and the sixth gear 139 are keyed to the output shaft 137. The gear and the shaft are connected through a key, so that the structure is simple and reliable.
As a specific embodiment, the fourth gear 136 is rotatably connected to one end of the reduction shaft 133 through a bearing 140. This allows the fourth gear 136 to rotate relative to the reduction shaft 133 to achieve three-stage reduction. Meanwhile, the connecting structure is simple, the installation is convenient, and the required installation space is less.
As a specific embodiment, the rotation axes of the input shaft 131, the reduction shaft 133, and the output shaft 137 are parallel to each other.
In a specific embodiment, a reinforcing pull rod 14 is disposed between the upper substrate 11 and the lower substrate 12. The reinforcing tie bar 14 is used to increase the stability of the connection structure between the upper substrate 11 and the lower substrate 12, thereby ensuring stable operation of each component in the novel gear reduction mechanism 10.
Further, two reinforcing pull rods 14 are disposed between the upper substrate 11 and the lower substrate 12.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
