Description

Technical Field

[0001] This utility model belongs to the field of speed reducer technology, specifically a small stepper motor speed reducer. Background Technology

[0002] The principle of a motor reducer is to convert the high-speed rotation of an electric motor into low-speed, high-torque rotation to meet the needs of different mechanical transmission systems. For example, by using gear combinations of different sizes, the speed can be reduced and the torque increased. By reducing the speed and increasing the output torque, the motor reducer helps to achieve more efficient mechanical motion and control.

[0003] Currently, there are still some problems with existing speed reducers in actual use. For example, existing speed reducers require a large amount of lubricating oil between the various reduction gears to ensure the transmission effect between them. However, the existing filling method is too complicated, which affects the efficiency of lubricating oil filling.

[0004] Therefore, a small stepper motor reducer is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problem of overly complex existing filling methods, a small stepper motor reducer is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The small stepper motor reducer of this utility model includes an upper housing, a lower housing is provided below the upper housing, multiple sets of reduction gears are provided inside the upper housing and the lower housing, a maintenance plate is installed on the top surface of the upper housing, a transmission shaft is provided between the upper housing and the lower housing, and an oil injection assembly is provided on the top surface of the upper housing. The oil injection assembly includes an oil reservoir, which is fixedly installed on the top of the upper housing.

[0007] Preferably, one end of the oil storage cylinder is fixedly connected to a discharge pipe, one end of the discharge pipe extends into the interior of the upper housing, a one-way valve is fixedly installed on the outer surface of the discharge pipe, a refueling pipe is fixedly connected to the outer surface of the oil storage cylinder, and a two-way valve is fixedly installed on the outer surface of the refueling pipe.

[0008] Preferably, the oil storage tank is internally fitted with a pusher disc, and one end of the pusher disc is fixedly connected to a pusher rod.

[0009] Preferably, a C-shaped frame is fixedly installed on the top surface of the upper housing, a vertical plate is fixedly installed on the top surface of the C-shaped frame, a threaded sleeve is fixedly installed inside the vertical plate, and a threaded rod is threaded into the inside of the threaded sleeve.

[0010] Preferably, a connecting plate is rotatably mounted on one end of the threaded rod, and one side surface of the connecting plate is fixedly connected to one end of the push rod.

[0011] Preferably, a knob is fixedly installed at the other end of the threaded rod, and multiple anti-slip grooves are equidistantly formed on the outer surface of the knob.

[0012] The beneficial effects of this utility model are:

[0013] This utility model provides a small stepper motor reducer, which drives the push plate to move into the oil storage tank through the push rod, squeezing the lubricating oil inside the oil storage tank and squeezing the lubricating oil into the discharge pipe, and finally into the upper and lower housings. This allows for convenient and quick injection of lubricating oil into the upper and lower housings, greatly increasing the convenience of lubricating oil injection.

[0014] This utility model provides a small stepper motor reducer. By holding a knob, the threaded rod is rotated in different directions inside the threaded sleeve, causing the threaded rod to move back and forth inside the threaded sleeve. During the movement, the connecting plate can be moved synchronously. Since the connecting plate is fixedly connected to one end of the push rod, the rotation of the threaded rod can drive the push rod to move, which controls the injection and intake of lubricating oil inside the oil reservoir. This makes the oil filling and refilling process in the oil reservoir more labor-saving and further improves the convenience of oil filling. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4 This utility model provides a small stepper motor reducer, including an upper housing 1, a lower housing 2 below the upper housing 1, multiple sets of reduction gears 6 inside the upper housing 1 and the lower housing 2, a maintenance plate 3 installed on the top surface of the upper housing 1, a transmission shaft 4 between the upper housing 1 and the lower housing 2, and an oil injection assembly on the top surface of the upper housing 1, the oil injection assembly including an oil reservoir 5, the oil reservoir 5 being fixedly installed on the top of the upper housing 1.

[0025] One end of the oil storage tank 5 is fixedly connected to the discharge pipe 7, and one end of the discharge pipe 7 extends into the interior of the upper housing 1. A one-way valve 8 is fixedly installed on the outer surface of the discharge pipe 7. A refueling pipe 9 is fixedly connected to the outer surface of the oil storage tank 5. A one-way valve 10 is fixedly installed on the outer surface of the refueling pipe 9. A pusher plate 11 is movably engaged inside the oil storage tank 5. A pusher rod 12 is fixedly connected to one end of the pusher plate 11.

[0026] During operation, the oil filling pipe 9 is first connected to an external pipeline. Then, the push rod 12 is moved to drive the push plate 11 to move outward inside the oil storage tank 5, thereby creating a negative pressure inside the oil storage tank 5. Under the action of negative pressure, lubricating oil is drawn into the oil storage tank 5 through the oil filling pipe 9. Then, the push rod 12 drives the push plate 11 to move inward into the oil storage tank 5, squeezing the lubricating oil inside the oil storage tank 5 and forcing it into the discharge pipe 7. Finally, the lubricating oil enters the upper shell 1 and the lower shell 2, thus enabling convenient and quick injection of lubricating oil into the upper shell 1 and the lower shell 2, greatly increasing the convenience of lubricating oil injection.

[0027] Furthermore, such as Figure 1-4As shown, a C-shaped frame 13 is fixedly installed on the top surface of the upper housing 1, and a vertical plate 14 is fixedly installed on the top surface of the C-shaped frame 13. A threaded sleeve 15 is fixedly installed inside the vertical plate 14, and a threaded rod 16 is threadedly connected inside the threaded sleeve 15. A connecting plate 17 is rotatably installed at one end of the threaded rod 16. One side surface of the connecting plate 17 is fixedly connected to one end of the push rod 12. A knob 18 is fixedly installed at the other end of the threaded rod 16. Multiple anti-slip grooves 19 are equidistantly opened on the outer surface of the knob 18. A scale groove 20 is opened on the outer surface of the push rod 12. The amount of lubricating oil fed can be directly observed through the scale groove 20, thereby greatly improving the accuracy of oil injection.

[0028] During operation, by holding the knob 18, the threaded rod 16 is rotated in different directions inside the threaded sleeve 15, causing the threaded rod 16 to move back and forth inside the threaded sleeve 15. During this movement, the connecting plate 17 is moved synchronously. Since the connecting plate 17 is fixedly connected to one end of the push rod 12, the rotation of the threaded rod 16 can drive the push rod 12 to move, which controls the injection and intake of lubricating oil inside the oil reservoir 5. This makes the oil filling and refilling process in the oil reservoir 5 more labor-saving, further improving the convenience of oil filling. In addition, the anti-slip groove 19 effectively increases the friction between the palm and the knob 18, preventing slippage between the palm and the knob 18 during the rotation process.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
