Description

Technical Field

[0001] The utility model relates to an integrated slewing bearing horizontal slewing reducer, belonging to the technical field of reducers. Background Art

[0002] The slewing reducer is an independent component composed of a gear drive, worm drive, or gear-worm drive enclosed in a rigid base. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator. It is widely used in modern machinery.

[0003] In addition, the exterior of the conventional horizontal slewing reducer is mainly composed of the base, the inner and outer rings of the slewing bearing, and the reducer has a large structure and high cost. In addition, the conventional horizontal slewing reducer is provided with an oil-free flanged bearing on the gear at the output end, which is connected to the base through the oil-free flanged bearing. If the output end and the input end have a fixed position, the transmission will be carried out by modifying the position and size of the intermediate transmission gear, or directly adding gears. However, the more gears there are, the lower the overall transmission efficiency is, which ultimately reduces the transmission effect of the slewing reducer. Summary of the invention

[0004] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide an integrated slewing bearing horizontal slewing reducer with simple structure, low cost, high transmission efficiency and simple and convenient maintenance and replacement.

[0005] The purpose of the utility model is achieved in this way:

[0006] An integrated slewing bearing horizontal slewing reducer comprises a base, one side of the base is an input end, the input end is connected to the motor input shaft of the motor, the motor input shaft is connected to the turbine worm, a circle of racks is provided at the top in the middle of the turbine worm, a slewing bearing is arranged above the turbine worm inside the base, a gear is arranged at the bottom of the slewing bearing, the rack of the turbine worm is meshed with the gear of the slewing bearing, the slewing bearing is driven to rotate by the turbine worm, a raceway is arranged inside the slewing bearing, balls are placed on the inner side of the raceway, and the slewing bearing is driven to output torque to the outside by ball transmission.

[0007] The bottom of the base is installed on the main beam of the solar support.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] This integrated slewing bearing horizontal slewing reducer replaces the inner ring of the slewing bearing with a base, which simplifies the structure of the reducer and reduces the overall cost. A raceway is added between the base and the output shaft, and balls are placed in the raceway. There is no sliding loss during ball transmission operation, and the transmission efficiency can reach 98% to 99%, which is higher than that of oil-free flanged bearings. Ball transmission only performs transmission and is subject to radial loads. If there is a need for replacement, only the balls need to be replaced without disassembly. Compared with disassembling oil-free flanged bearings, replacing balls is simpler, easier to obtain, and cheaper. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] See also Figures 1 to 3 The utility model relates to an integrated slewing bearing horizontal slewing reducer, which includes a base 1, the bottom of which is mounted on the main beam of a solar support, thereby fixing the reducer. One side of the base 1 is an input end, which is connected to a motor input shaft 3 of a motor 2, and the motor input shaft 3 is connected to a worm gear 4, and a circle of racks is provided at the top of the middle of the worm gear 4.

[0015] A slewing bearing 5 is arranged above the worm gear 4 inside the base 1. A gear is arranged at the bottom of the slewing bearing 5. The rack of the worm gear 4 meshes with the gear of the slewing bearing 5. The worm gear 4 drives the slewing bearing 5 to rotate. A raceway 6 is arranged inside the slewing bearing 5. Balls 7 are placed on the inner side of the raceway 6. The slewing bearing 5 is driven to output torque to the outside through the transmission of the balls 7. Since there is no sliding loss during the operation of the ball transmission, the transmission efficiency can reach 98% to 99%, which greatly improves the transmission efficiency. And the gear stop diameter can be adjusted by increasing or decreasing the number of balls, so as to meet various center distance positions, so that the installation and use are not restricted. The base 1 also replaces the inner ring of the slewing bearing 5, simplifies the structure of the reducer, and reduces the overall cost.

[0016] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
