Description

Technical Field

[0001] This utility model relates to the field of vertical high-power mixer technology, and in particular to a rotor gearbox for a vertical high-power mixer. Background Technology

[0002] In industrial production, vertical high-intensity mixers are important pieces of equipment, widely used in material mixing and other processes. Their rotor gearbox, as the core transmission component, plays a crucial role in the mixer's performance and operational stability.

[0003] However, the existing vertical high-power mixer rotor gearbox uses a standard modular reducer, which is large in size and has certain limitations in space arrangement. The radial force of the output bearing cannot meet the actual requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a rotor gearbox for a vertical high-power mixer, which aims to solve the technical problems of existing vertical high-power mixer rotor gearboxes using standard modular reducers, which are large in size, have certain limitations in space arrangement, and whose output bearing radial force cannot meet actual requirements.

[0005] To achieve the above objectives, this utility model employs a rotor gearbox for a vertical high-power mixer, comprising a housing, an input gear shaft, a transmission gear, an input shaft support, an output shaft, a seal, and a bearing cantilever support. The input gear shaft is rotatably connected to the housing via the input shaft support, and the output shaft is rotatably connected to the housing via the bearing cantilever support. Both the seal and the transmission gear are mounted on the output shaft. The transmission gear is connected to the input gear shaft, and the seal is located at the end of the output shaft furthest from the bearing cantilever support.

[0006] The output shaft includes a rotating section and a connecting section. The rotating section is rotatably connected to the housing and fixedly connected to the transmission gear. The connecting section is fixedly connected to the rotating section.

[0007] The rotor gearbox of the vertical high-power mixer also includes a support plate and fasteners, and the support plate is fixed to the housing by the fasteners.

[0008] The rotor gearbox of the vertical high-power mixer also includes a bearing cantilever support lubricant injection port, which is located on the gearbox body.

[0009] The input gear shaft has a waist-shaped hole.

[0010] The fastener includes two bolts, one end of which passes through the support plate and is tightened onto the housing.

[0011] This utility model discloses a rotor gearbox for a vertical high-power mixer. In practical use, when the input gear shaft rotates, it drives the output shaft to rotate through the transmission gear, thereby driving the external components connected to the output shaft to rotate. The seal is used to seal the output shaft, and the bearing cantilever support is used to bear the axial and radial forces of the output shaft. The input shaft support is used to bear the axial and radial forces of the input gear shaft. This utility model adopts a single-stage transmission reducer. The entire reducer structure is compact and has high transmission efficiency. The radial force of the output bearing meets the actual design requirements. This method solves the technical problem that the rotor gearbox of the existing vertical high-power mixer uses a standard modular reducer, which has a large volume, certain spatial limitations, and the radial force of the output bearing cannot meet the actual requirements.

[0025] In this specific embodiment, by passing one end of each of the two bolts 111 through the support plate 110 and tightening them onto the housing 101, the seal 105 can be covered, and conversely, it is convenient to disassemble the seal 105 for replacement.

[0026] Meanwhile, the rotor gearbox of the vertical high-power mixer also includes a bearing cantilever support lubricant injection port 112, which is disposed on the housing 101.

[0027] In this specific embodiment, by providing the bearing cantilever support lubricant injection port 112, lubricant can be injected to improve the lubrication effect of the bearing cantilever support 106.

[0028] In the rotor gearbox of a vertical high-power mixer according to this invention, when the input gear shaft 102 rotates, it drives the output shaft to rotate through the transmission gear 103, thereby driving the external components connected to the output shaft to rotate. The seal 105 is used to seal the output shaft. The bearing cantilever support 106 is used to bear the axial and radial forces of the output shaft.
