[0002] A speed reducer mainly consists of components such as a housing, gears, and gear shafts. The gear shaft is mainly used to transmit power and torque, enabling the gears to work smoothly and achieve a speed reduction effect. The gear shaft can also play a role in supporting and fixing the gears, ensuring the precise fit between adjacent gears, and guaranteeing the stable and reliable operation of the entire speed reducer. During the processes of packing, transporting, placing, and taking the gear shafts of the speed reducer, multiple gear shafts are often directly placed in a storage box, and the storage box can be carried to simultaneously transfer multiple gear shafts.

[0003] During the processes of packing, transporting, placing, and taking the gear shafts of the speed reducer, multiple gear shafts are often directly placed in a storage box. The multiple gear shafts in the storage box are in contact with each other. During the transfer process of the gear shafts, adjacent gear shafts are prone to collide with each other, causing slight damage to the surface of the gear shafts, thereby affecting the subsequent assembly accuracy. Therefore, the present application provides a protection component for a gear shaft of a speed reducer to meet the requirements. Summary of the Invention

[0006] A protection component for a gear shaft of a speed reducer includes a bottom plate. Shaft bodies are placed on the bottom plate, and the number of the shaft bodies is several. A plurality of partition strips are fixed on the bottom plate, and the partition strips are used to separate adjacent two shaft bodies. Right-angled triangular blocks are fixed on the sides of the partition strips, and the right-angled triangular blocks are fixed on the bottom plate. The hypotenuse of the right-angled triangular block is in fit with the circumferential surface of the shaft body. Two stop strips are fixed on the top of the bottom plate, and the two stop strips are respectively fixed at the two ends of the partition strip.

[0028] Such as Figures 1-4As shown in the figure, an embodiment of the present utility model provides a protection assembly for a reduction gear shaft, including a bottom plate 2 on which a shaft body 1 is placed. The number of the shaft bodies 1 is several. A plurality of partition strips 3 are fixed on the bottom plate 2. The partition strips 3 are used to separate adjacent two shaft bodies 1, preventing collision between adjacent two shaft bodies 1, thereby preventing damage to the surface of the shaft body 1, and improving the subsequent assembly accuracy of the shaft body 1. The distance between adjacent two partition strips 3 is the same, and the partition strips 3 with different distances can be set according to shaft bodies 1 with different diameters, so as to adapt to the use of shaft bodies 1 with different diameters. Right-angled triangular blocks 4 are fixed on the side surfaces of the partition strips 3. The right-angled triangular blocks 4 are fixed on the bottom plate 2. The hypotenuse of the right-angled triangular block 4 is attached to the circumferential surface of the shaft body 1. The right-angled triangular block 4 is used to improve the connection strength between the partition strip 3 and the bottom plate 2 on the one hand, and on the other hand, position the shaft body 1 through the inclined surfaces of two opposite right-angled triangular blocks 4, preventing the shaft body 1 from shaking between adjacent two partition strips 3. Two retaining strips 8 are fixed on the top of the bottom plate 2. The two retaining strips 8 are respectively fixed at both ends of the partition strip 3. The side surface of the retaining strip 8 is attached to the end of the shaft body 1. The retaining strip 8 is used to prevent the shaft body 1 from slipping out between adjacent two partition strips 3. Only a limited number of shaft bodies 1 can be placed on the bottom plate 2, and a small number of shaft bodies 1 can be carried at one time, preventing the situation of excessive labor intensity caused by carrying too many shaft bodies 1 at one time, and reducing the labor intensity of the staff.

[0029] As Figure 4 shown, in this embodiment, a positioning curved surface 12 is provided on the hypotenuse of the right-angled triangular block 4. The positioning curved surface 12 is attached to the circumferential surface of the shaft body 1. Through the attachment of the positioning curved surface 12 to the circumferential surface of the shaft body 1, the shaft body 1 is placed more stably between adjacent two partition strips 3.

[0030] As Figure 1 shown, in this embodiment, a picking groove 9 is formed on the side surface of the retaining strip 8. The picking groove 9 is semi-circular. Through the picking groove 9, it is convenient for the staff's fingers to hold against both ends of the shaft body 1 to take out the shaft body 1 from between adjacent two partition strips 3.

[0031] As Figure 3 shown, in this embodiment, a guiding block 10 is fixed on the retaining strip 8. An inclined guiding surface is provided on the side of the guiding block 10 close to the shaft body 1. When the shaft body 1 is placed in the space formed by the partition strip 3 and the retaining strip 8, it is convenient to place the shaft body 1 flat in the corresponding space through the guidance of the inclined guiding surface on the guiding block 10.

[0032] As Figure 4As shown in the figure, in this embodiment, a plurality of square bars 5 are fixed to the bottom of the bottom plate 2. A notch is formed in the bottom of the square bar 5, and a rubber pad 6 is fixed to the inner wall of the notch. A plurality of card slots 7 are formed in the partition bar 3. The number of square bars 5 is three or more, and is specifically increased or decreased according to the length of the shaft body 1. The number of card slots 7 on each partition bar 3 corresponds to the number of square bars 5. When there are more shaft bodies 1 to be transported, the plurality of shaft bodies 1 are respectively placed on a plurality of bottom plates 2, and then the plurality of bottom plates 2 are stacked, so that the upper bottom plate 2 fits on the lower partition bar 3, and the square bar 5 at the bottom of the upper bottom plate 2 is stuck in the card slot 7 on the lower partition bar 3, realizing the positioning between the upper and lower bottom plates 2. When the square bar 5 is stuck in the card slot 7, the rubber pad 6 fits on the top of the lower shaft body 1, realizing the positioning of the shaft body 1 and improving the stability of the shaft body 1 during transportation. When only transporting the shaft body 1 on a single bottom plate 2, the bottom plate 2 is supported by the square bar 5 to prevent the bottom plate 2 from contacting the ground or the tabletop of the bottom plate 2, facilitating the operator to hold the bottom plate 2 from the bottom to transport the shaft body 1.

[0033] As Figure 4 shown in the figure, in this embodiment, the rubber pad 6 is arc-shaped, and the arc-shaped rubber pad 6 can stably fit on the surface of the shaft body 1, thereby improving the positioning stability of the shaft body 1.

[0034] As Figure 1 shown in the figure, in this embodiment, a guiding surface 13 is formed on the side surface of the inner wall of the card slot 7. When the square bar 5 is stuck in the card slot 7, the guiding surface 13 facilitates guiding the square bar 5 into the card slot 7.

[0035] As Figure 2 and Figure 3 shown in the figure, in this embodiment, an anti-slip strip 11 is fixed to the bottom of the bottom plate 2. When transporting the shaft body 1, hold the position corresponding to the anti-slip strip 11 at the bottom of the bottom plate 2 with the hand. The anti-slip strip 11 prevents slipping when holding the bottom of the bottom plate 2, thereby improving the stability during transportation.

[0036] Working principle: The plurality of shaft bodies 1 are sequentially placed between two adjacent partition bars 3. The partition bars 3 prevent collision between two adjacent shaft bodies 1. The stop bar 8 is fixed to the end of the partition bar 3 to prevent the shaft body 1 from slipping out between two adjacent partition bars 3 in its axial direction. A right-angled triangular block 4 is fixed to the side of the partition bar 3. The shaft body 1 fits on the positioning curved surface 12 on the hypotenuse of the right-angled triangular block 4, and the positioning curved surface 12 prevents the shaft body 1 from shaking between two adjacent partition bars 3.

[0037] When there are many shafts 1 to be transported, multiple shafts 1 can be placed on multiple bottom plates 2 respectively, and then the multiple bottom plates 2 are stacked so that the upper bottom plate 2 fits on the lower partition strip 3, and the square bar 5 at the bottom of the upper bottom plate 2 is stuck in the card slot 7 on the lower partition strip 3 to realize the positioning between the upper and lower bottom plates 2. When the square bar 5 is stuck in the card slot 7, the rubber pad 6 fits on the top of the lower shaft 1 to realize the positioning of the shaft 1 and improve the stability of the shaft 1 during transportation;

[0038] When the shaft 1 needs to be taken out from between adjacent partition strips 3 after the shaft 1 is transported to the designated location, two fingers are respectively extended to the positions of the two digging slots 9 at both ends of the same shaft 1, and the shaft 1 is resisted at both ends from the positions of the digging slots 9 and moved upward, so that the shaft 1 can be taken out from between the adjacent two partition strips 3. After the upper shaft 1 is taken out, the upper bottom plate 2 is taken off from the lower partition strip 3, and then the lower shaft 1 can be taken out in the same way.

[0039] The present utility model covers any alternatives, modifications, equivalent methods and solutions made on the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model without the description of these details.

[0040] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model.
