[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, a gear reduction box comprises a body 1 and a gear shaft 2 and a large shaft 4 rotatably mounted on the body 1. The gear shaft 2 comprises a gear with spur teeth. The gear shaft 2 and the large shaft 4 are respectively located on both sides of the body 1. A small bearing end cover 16 and a small end cover 17 are arranged at both ends of the gear shaft 2. A large bearing end cover 18 and a large end cover 19 are arranged at both ends of the large shaft 4. The gear shaft 2 is fixed by a plurality of M8X16 hexagonal screws 20. When the M8X16 hexagonal screws 20 are fixed, a large gasket or a small gasket is arranged to fill the gap. The gear shaft 2 is connected to the first cylindrical roller bearing 3. The large shaft 4 is connected to a distance ring 6 to fix the bearing position, ensure the stability of the rolling elements inside the bearing, and prevent them from displacement or loosening during operation. The large shaft 4 is connected to the second cylindrical roller bearing 5. A large gear 8 is inserted into the large shaft 4. The gear shaft 2 is connected to the large gear 8 through spur teeth. The large gear 8 is connected to the large shaft 4 through a connecting key.

[0027] The left and right connections between the body 1 and the upper box cover 9 are fixed by M10 hexagon nuts 21 and M12X50 external hexagon screws 22 on the upper body 1, and the front and rear connections between the body 1 and the upper box cover 9 are fixed by M10X45 external hexagon screws 23. The M12X50 external hexagon screws 22 and M10X45 external hexagon screws 23 are used to fill the gaps with spring washers at the connection with the upper box cover 9. The upper box cover 9 is designed to be a curved shape with a high front end and a low rear end, so as to meet the requirements of a large and a small internal gear set. At the same time, a solid transparent peephole cover plate 7 made of acrylic material is arranged above the upper box cover 9, which is connected and fixed by M6X12 external hexagon screws 24, and the transparent peephole cover plate 7 and the upper box cover 9 are filled with a vent gasket 10. The user can observe the working status of the internal gears of the gear reducer through the transparent peephole cover plate 7 above, and can also observe the status of the lubricating oil between the gear sets. At the same time, a handle-shaped vent 11 with a through hole is arranged on the transparent peephole cover plate 7 to ensure the ventilation of the entire gear reduction box.

[0028] like Figure 5 As shown, through the transparent peephole cover 7, the specific conditions of the large gear and other structures inside the gear reduction box can be observed.

[0029] The body 1 is provided with a taper pin 15 for positioning and connecting the body 1 and the upper box cover 9; the lower front end of the body 1 is provided with a screw plug 12 and a screw plug gasket 14, which can make the body 1 more secure and prevent lubricating oil leakage. An oil dipstick 13 is provided above the screw plug 12 and is fixed obliquely to the lower front end of the body 1.

[0030] After the workpieces are assembled according to the drawing, lubricating oil is used inside the reduction box to reduce the friction between the workpieces, and the amount of lubricating oil in the engine is added through the oil dipstick 13 on the body. After the reduction box is connected to the control device and powered on, the gear shaft 2 is driven by the motor, and the spur teeth on the gear shaft 2 are used to drive the large gear 8 to rotate, so that the large gear 8 drives the large shaft 4 to rotate through the connecting key, thereby achieving the effect of deceleration by driving the large gear with the small gear. The specific degree of deceleration effect can be achieved by changing the rotation speed of the gear shaft 2 by the motor, that is, controlling the rotation speed of the large gear 8 driven by the gear shaft 2.

[0031] Advantages of the implementation of the utility model: through the above technical scheme, after assembly and power is turned on, the motor drives the gear shaft, and the gear shaft drives the large gear to rotate through the spur teeth, thereby driving the large shaft to rotate through the connecting key, so that the large gear is driven by the small gear to obtain a deceleration effect, and through the transparent peephole cover, the working state of the internal structure combination and the state of the lubricating oil between the gear groups can be observed more clearly, the structure is simple, the convenience of assembly is improved, and the work quality and efficiency are improved.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
