[0027] Schematic diagram of gears that are easy to lubricate

[0028] refer to Figures 1 to 3 According to a preferred embodiment of the utility model, a gear that is easy to lubricate is provided. It should be noted that the structure of the gear that is easy to lubricate is as follows: Figure 2As shown, it includes a gear body 10, and the gear body 10 is arranged to cooperate with the external drive shaft, that is, the external drive shaft is arranged to drive the gear body 10 to rotate. It should also be noted that the center of the gear body 10 has a first connecting hole 101, and the first connecting hole 101 is arranged to cooperate with the external drive shaft, and the size of the first connecting hole 101 is smaller than the cross-sectional size of the external drive shaft, that is, the cooperation mode between the external drive shaft and the first connecting hole 101 can be implemented as an interference fit, so that the gear body 10 can rotate synchronously with the external drive shaft.

[0029] It should also be noted that the gear body 10 also has a plurality of evenly distributed second connection holes 102, which are located around the first connection hole 101, and each of the second connection holes 102 is a stepped hole. In addition, the plurality of second connection holes 102 are preferably 4, and all penetrate the gear body 10.

[0030] Specifically, the outer wall of the gear body 10 also has a plurality of evenly distributed tooth grooves 103, and the bottom wall forming the tooth grooves 103 is an inclined surface. Figure 1 As shown, the large hole of the second connection hole 102 is located on the left side, and the small hole of the second connection hole 102 is located on the left side, and at the same time, the two ends of the bottom wall of the tooth groove 103 are respectively opposite to the two ends of the second connection hole 102, that is, the bottom wall of the tooth groove 103 extends upward from the left side to the right side. It should also be noted that the above-mentioned gear body 10 is horizontally arranged, and at the same time, the above-mentioned gear part is lubricated with grease, but the bottom wall of the gear of our company's previous gear parts is usually designed to be flat, so that when the user applies grease, in order to ensure that the grease can effectively cover the bottom wall of the tooth groove, the through groove will be squeezed on the side of the gear, that is, squeezed in the direction close to the second connection hole 102, rather than directly squeezed into the tooth groove 103, and then the above method will squeeze the grease into the second connection hole 102, resulting in a waste of grease. The utility model has an oblique tooth groove 103 surface design, which allows the user to squeeze a small amount of grease toward the bottom wall forming the tooth groove 103. The oblique design will not cause the grease to fall directly to the bottom, but will hang on the bottom wall forming the tooth groove 103 and creep downward. Then the user can follow this circle of grease and squeeze another circle of grease directly on the outside of the circle of grease, thereby ensuring that the amount of grease is sufficient when the gear rotates.

[0031] It should also be noted that the angle between the bottom wall forming the tooth groove 103 and the axis of the gear body 10 is 3-6°.

[0032] Specifically, the gear that is easy to lubricate also includes a matching plate 20, which is arranged on one side of the gear body 10 and is close to the small hole of the second connection hole 102, and the matching plate 20 is a thin plate. The matching plate 20 is screwed to the gear body 10. In addition, the matching plate 20 has a third connection hole 201 and a plurality of evenly distributed fourth connection holes 202, and the plurality of fourth connection holes 202 correspond to the plurality of second connection holes 102 one by one, and the third connection hole 201 corresponds to the first connection hole 101. It is worth mentioning that the size of the third connection hole 201 is consistent with the size of the first connection hole 101, and the size of the fourth connection hole 202 is consistent with the size of the second connection hole 102. It is worth mentioning that the matching plate 20 is a circular plate, and the size of the matching plate 20 is larger than the size of the tooth root circle of the gear body 10.

[0033] Furthermore, the center of the side of the matching plate 20 away from the gear body 10 also has a protrusion 21 , and the third connecting hole 201 also passes through the protrusion 21 .

[0034] Furthermore, the side of the mating plate 20 close to the gear body 10 also has a plurality of evenly distributed protrusions 22, and the plurality of protrusions 22 are respectively placed in the plurality of tooth grooves 103. Specifically, in order to facilitate the assembly of the above-mentioned mating plate 20, the bottom of the protrusion 21 is spaced apart from the bottom wall forming the tooth groove 103 by a predetermined distance, so that the user can adjust the position of the mating plate 20 during the assembly process. It should also be noted that the gap between the bottom of the protrusion 21 and the bottom wall forming the tooth groove 103 is closed by welding, thereby improving the connection strength between the mating plate 20 and the gear body 10. In addition, the side of the protrusion 22 close to the gear body 10 is a slope. It should also be noted that the above-mentioned gear body 10 also cooperates with another gear, specifically as Figure 1 As shown, since it is placed horizontally, if the installation position, that is, the size of the gear meets the requirements, the tooth top part of the gear will not contact the above-mentioned protruding block 22, that is, the above-mentioned protruding block 22 can also ensure that the tooth width of the gear matched with the utility model meets the requirements. In addition, in the process of squeezing grease, the multiple protruding blocks 22 of the utility model can also limit the position of the grease that creeps downward, so that the pre-extruded grease will not fall to the outside.

[0035] In summary, the gear that is easy to lubricate based on the embodiment of the present application is explained, which provides the gear that is easy to lubricate with advantages such as grease being able to adhere to the bottom wall of the tooth groove, convenient lubrication, and high practicality.

[0036] It is worth mentioning that in the embodiment of the present application, the gear structure that is easy to lubricate is simple, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the gear that is easy to lubricate provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.
