Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0023] With reference to Figure 1 And Figure 2 An embodiment provided by the utility model: a double-input right-angle shaft bevel gear reducer for the mixing industry, comprising a box body 1, the box body 1 is made of high-strength cast iron material, which ensures its good wear resistance and corrosion resistance, and also has excellent shock resistance, ensuring long-term stable operation. This design enables the entire device to maintain high efficiency in harsh working environments. The inside of the box body 1 is centrally provided with an output shaft 2, which is used to output and transmit driving force. The outside of the output shaft 2 is rotatably connected with a large gear 3, and the position change of the large gear 3 can drive the output shaft 2 to change position. The outside of the large gear 3 is provided with a gear shaft 4 on both sides, and the position change of the gear shaft 4 can drive the large gear 3 to change position. The outside of the gear shaft 4 is provided with a bevel gear 5, and the position change of the bevel gear 5 can drive the gear shaft 4 to change position. The outside of the box body 1 is provided with a bevel gear shaft 6 on both sides, and the axis of the bevel gear shaft 6 is perpendicular to the axis of the output shaft 2. The outside of the bevel gear shaft 6 is engaged with the outside of the bevel gear 5, and the position change of the bevel gear shaft 6 can drive the bevel gear 5 to change position. The two sides of the box body 1 are fixedly connected with a connecting flange 7, and the box body 1 has a fixed position effect on the two connecting flanges 7.
[0024] The outside of the box body 1 is fixedly connected with a driving assembly, which comprises two motors 8. The outside of the two motors 8 is mounted on the outside of the connecting flange 7, and the connecting flange 7 has a fixed position effect on the outside of the motor 8. The driving end of the motor 8 is fixedly connected to the outside of the bevel gear shaft 6. When the motor 8 is started, the position change of the driving end of the motor 8 can drive the bevel gear shaft 6 to rotate. The motor 8 selects a high-performance AC asynchronous motor, which has the characteristics of high efficiency and energy saving, and can effectively reduce energy consumption costs. At the same time, this motor 8 also has good overload protection capability, and can operate stably even in extreme working conditions. The motor 8 not only has the characteristics of high efficiency and energy saving, but also adopts advanced cooling technology, which ensures that the motor 8 can still maintain good heat dissipation effect under long-time high-load operation, thereby prolonging the service life of the motor 8 and reducing the maintenance requirements.
[0025] The outer part of the box 1 is equipped with an oil separation sleeve 10, and the inside of the box 1 is filled with lubricating oil 11.

The dry oil lubrication system 9 further reduces the maintenance requirements and reduces the operating cost. The dry oil lubrication system 9 uses long-acting lubricating grease, which can adapt to various complex working conditions and provide long-lasting lubrication effect, reducing the downtime and maintenance workload of the equipment. This system can also adjust the amount of lubricant according to actual needs to achieve precise control.

The oil separation sleeve 10 is made of oil-resistant rubber material, which has good sealing performance and high temperature resistance, effectively preventing the lubricating oil 11 from leaking. The design of the oil throwing ring 13 can ensure that the lubricating oil 11 will not enter the bearing 14 area, thereby prolonging the service life of the bearing 14, the dry oil lubrication system 9 further reduces the maintenance requirement, reduces the operation cost, and the whole speed reducer is also a left-right symmetrical structure, which not only simplifies the equipment installation, but also the symmetrical speed reducer can effectively reduce the rotational inertia of the system, so that the system can respond to changes more quickly and accurately, timely control start-stop and speed change, and the dry well seal is also prevented from oil leakage of the output end, avoiding damage to the equipment.
