Description

Technical Field

[0001] The utility model relates to the technical field of reduction motor gears, and particularly relates to a gear for a reduction motor. Background Technique

[0002] In the use of motors in the mechanical field, motors are often used in combination with speed reducers. Most traditional reduction motors are connected by using a finished motor and a finished speed reducer, and the rear end cover of the speed reducer box and the front end cover of the motor are respectively provided. The rear end cover of the reduction box and the front end cover of the motor are connected through an intermediate link. However, this connection method will generate vibration during the operation of the equipment, especially when the motor rotates at a low speed, which affects the stability of the equipment. Therefore, a new type of reduction motor is urgently needed.

[0003] The utility model patent with the authorization announcement number CN215580749U discloses a reduction motor. The utility model includes a housing, a reduction chamber and a motor groove arranged in the housing, and a through hole connecting the motor groove and the reduction chamber. A reduction gear set is arranged in the reduction chamber, a motor is installed in the motor groove, the outside of the motor abuts against the inside of the motor groove, the driving shaft of the motor passes through the through hole and extends into the reduction chamber, a driving gear is installed at the end of the driving shaft away from the motor, the driving gear meshes with the input end of the reduction gear set, and an output shaft is arranged at the output end of the reduction gear set, which has the advantage of stable operation and solves the problem of vibration generated during the operation of traditional reduction motor equipment.

[0004] Although the above utility model can solve the problem of vibration generated by traditional reduction motors during the operation of the equipment, during the operation of the gears, lubricating oil needs to be added to prevent the gears from rubbing and wearing each other. However, the depths of the reduction chambers of the above reduction motors are different, resulting in the lubricating oil placed inside may flow towards the depths. When the liquid level is too low and the user does not add lubricating liquid in time, the gears located at a high position cannot be conveniently lubricated by the lubricating oil. In view of this, we propose a gear for a reduction motor. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Please refer to Figures 1 - 5 , this embodiment provides a technical solution:

[0028] A gear for a speed reduction motor includes an outer shell 1, and a motor 2 is installed inside the right surface of the outer shell 1. A cavity is formed inside the left side of the outer shell 1. A lower gear set 11 is rotatably installed on the lower side of the cavity, and an upper gear set 12 is rotatably installed on the upper side of the cavity. The left surfaces of the two gears in the lower gear set 11 are both connected with an auxiliary mechanism 13. The auxiliary mechanism 13 includes an auxiliary inner disk 131 and an auxiliary outer disk 132 fixedly connected to the side surface of the auxiliary inner disk 131. Through the above mechanism, when the liquid level inside the cavity is too low, the auxiliary mechanism 13 can transport the lubricating liquid at a lower position to the gear.

[0029] Further, a through hole 1311 is formed in the middle position of the side surface of the auxiliary inner disk 131, and an auxiliary groove 1312 is formed on the side surface of the auxiliary inner disk 131. The through hole 1311 is for a rotating rod to pass through.

[0030] Further, a plurality of transport grooves 134 are formed on the side surface of the auxiliary outer disk 132, and a plurality of drainage grooves 133 are formed on the lower side of the transport grooves 134 to assist in guiding the movement of the lubricating liquid.

[0031] In this embodiment, a rotating block 1341 is provided on the lower side of the transport groove 134, and a connecting block 1342 is welded to the right side of the lower surface of the rotating block 1341.

[0032] In this embodiment, the thickness of the auxiliary inner disk 131 is greater than the thickness of the auxiliary outer disk 132, and a gap is left between the auxiliary outer disk 132 and the side walls of the surrounding outer shell 1.

[0033] In this embodiment, the cross-section of the conveying groove 134 is in the shape of a right trapezoid, and a rotating groove is formed on the right side of the lower surface of the conveying groove 134. The hypotenuse of the conveying groove 134 faces the center position of the auxiliary inner disk 131.

[0034] In this embodiment, the connecting block 1342 is rotatably connected to the inside of the rotating groove. The cross-section of the rotating block 1341 is in the shape of a right triangle, and the hypotenuse faces the center direction of the auxiliary inner disk 131.

[0035] In this embodiment, the drainage groove 133 is inserted into the inside of the conveying groove 134. The inner side surface of the drainage groove 133 is arc-shaped, which is convenient for the lubricating fluid to flow.

[0036] It should be noted that the structures and working principles of the housing 1, the motor 2, the lower gear set 11, and the upper gear set 12 involved in this embodiment are all publicly known technologies in the prior art and will not be elaborated here.

[0037] During the specific use of the gear of the reduction motor in this embodiment, during use, first place the auxiliary mechanism 13 with the auxiliary groove 1312 facing upwards horizontally. Then apply glue to the auxiliary groove 1312. Next, align the gear that needs to use the auxiliary mechanism 13 and place it flat on the surface of the auxiliary inner disk 131 through the through hole 1311. After waiting for it to be firmly fixed, install the gear on the lower gear set 11. When the gear rotates, it will drive the auxiliary mechanism 13 to rotate synchronously. When the drainage groove 133 moves to the lower side during rotation, it will lift the lubricating fluid on the lower side. When the drainage groove 133 moves to the upper side, the lubricating fluid carried in the drainage groove 133 and the lubricating fluid lifted from the surface of the auxiliary outer disk 132 will flow to the gear.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
