[0004] The objective of this utility model can be achieved through the following technical solution: A novel lubrication and reduction mechanism for a gearbox reducer, characterized in that the reduction mechanism includes a transmission shaft disposed within the reducer, a large gear with multiple teeth on the transmission shaft, and a transmission seat assembly tightly fitted at the position of the adjacent large gear on the transmission shaft. The transmission seat assembly consists of a first transmission seat and a second transmission seat connected to each other. Both the first and second transmission seats have notches, which form a mounting groove. A limiting plate is installed in the mounting groove. The limiting plate has an outwardly extending L-shaped fixing rod. The end of the L-shaped fixing rod extends to the teeth of the large gear, and a small gear meshes with the teeth. The small gear is spaced from the end of the L-shaped fixing rod. The end of the L-shaped fixing rod has a lubrication mechanism for spraying oil onto the teeth.

[0005] In the above-mentioned novel lubrication and reduction mechanism for a gearbox reducer, the lubrication mechanism includes an oil reservoir formed on the top of an L-shaped fixed rod. The bottom end of the L-shaped fixed rod has a splash guard with a parallelogram longitudinal section and the port facing the gear teeth. Multiple oil outlet holes are opened on the L-shaped fixed rod at positions corresponding to the oil reservoir. A cover is connected to the oil reservoir.

[0006] In the aforementioned novel lubrication and deceleration mechanism for a gearbox reducer, the limiting disc has limiting rods at both ends that extend into the transmission seat one and the transmission seat two.

[0007] In the aforementioned novel lubrication and reduction mechanism for a gearbox reducer, the first transmission seat and the second transmission seat are connected by multiple screws.

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 As shown, this novel lubrication and reduction mechanism for a gearbox reducer includes a drive shaft 1 installed inside the reducer. The drive shaft 1 has a large gear 3 with multiple toothed sections 2. A transmission seat assembly is tightly fitted at the position of the adjacent large gear 3 on the drive shaft 1. The transmission seat assembly consists of a first transmission seat 4 and a second transmission seat 5 connected to each other. Both the first and second transmission seats 4 and 5 have notches, forming a mounting groove. A limiting disc 6 is installed in the mounting groove. The limiting disc 6 has an outwardly extending L-shaped fixing rod 7. The end of the L-shaped fixing rod 7 extends to the toothed section 2 of the large gear 3, and a small gear 8 meshes with the toothed section 2. The small gear 8 is spaced from the end of the L-shaped fixing rod 7. The end of the L-shaped fixing rod 7 has a lubrication mechanism for spraying oil onto the toothed section 2.

[0014] To elaborate further, the lubrication mechanism includes an oil reservoir 9 formed at the top of the L-shaped fixing rod 7. The bottom of the L-shaped fixing rod 7 has a splash guard 10 with a parallelogram-shaped longitudinal section and its port facing the gear tooth portion 2. Multiple oil outlet holes 11 are opened on the L-shaped fixing rod 7 at positions corresponding to the oil reservoir 9. A cover 13 is connected to the oil reservoir 9. The rear end of the transmission shaft 1 is driven by a geared motor. The oil reservoir 9 contains lubricating grease. Under the action of centrifugal force, the L-shaped fixing rod 7, on the one hand, uses the dynamic heat of the product to form the lubricating grease into oil, and on the other hand, throws the oil out and sprays it in a direction onto the gear tooth portion 2 under the action of the splash guard 10 to lubricate the transmission of the large and small gears 8. In addition, some oil is sprayed onto the transmission shaft 1, which can also lubricate the components installed on the transmission shaft 1 and reduce transmission wear.

[0015] To elaborate further, the limiting disc 6 has limiting rods 12 at both ends that extend into the transmission seat 4 and the transmission seat 5, which serve as positioning tools.

[0016] Preferably, the transmission seat 4 and the transmission seat 5 are connected by multiple screws.

[0017] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0018] Although this document frequently uses terms such as drive shaft 1, gear teeth 2, large gear 3, drive seat one 4, drive seat two 5, limiting plate 6, L-shaped fixing rod 7, small gear 8, oil reservoir 9, splash guard 10, oil outlet 11, limiting rod 12, and cover 13, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
