Description

Technical Field

[0001] The utility model relates to the technical field related to lifting reducers, and in particular to a synchronous lifting reducer. Background Art

[0002] At present, industrial robots are widely used in the fields of plastics industry, automobile industry, electronic products industry, pharmaceutical industry and food industry. Its main function is to move parts and assemble them, which greatly reduces the workload of workers and improves the actual production capacity of the production line. It makes product quality stable and efficient, and facilitates technicians to understand the actual production situation on site in time, control product quality, reduce product size deviations caused by human operating errors, and has strong traceability. A reducer is needed to brake the elevator during the handling and lifting process.

[0003] At present, the existing AGV trolley uses a reducer to lift when it needs to be lifted after moving. However, the low precision of the existing lifting reducer leads to unstable platform lifting, and the torque and repeated positioning accuracy cannot meet the current market requirements. The cost is high and the strength is low. The synchronous lifting reducer is powered by a servo motor, and the two output shafts drive the platform to lift. The output torque of the output shaft is the same in size and direction. In this regard, this solution specially proposes a synchronous lifting reducer. Utility Model Content

[0004] In order to overcome the defects of the prior art, the utility model proposes a synchronous lifting reducer to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is implemented as follows: a synchronous lifting reducer includes an output shaft, a planetary reducer, a reversing reducer, an intermediate reducer, bearings, an intermediate shaft and gears. The output shaft is movably arranged at the center of the top two ends of the reversing reducer, and the top of the output shaft extends through and extends to the top outside of the reversing reducer. The intermediate reducer is fixedly installed with bolts at the center of one side of the bottom of the reversing reducer. The planetary reducer is fixedly installed at the bottom center of the intermediate reducer on a side away from the reversing reducer. A plurality of the intermediate shafts are evenly arranged between the output shafts in the reversing reducer, and the gears are fixedly installed on the outer periphery of the middle end of the intermediate shaft. A plurality of bearings are arranged at both ends of the intermediate shaft in the reversing reducer.

[0006] Preferably, the gears are welded and fixed to the outer periphery of the middle end of the intermediate shaft, and the gears are welded and fixed to the output shaft in the reversing reduction box, and the gears on the intermediate shaft and the output shaft are adjacently meshed and connected.

[0007] Preferably, the bearings are fixedly mounted at the upper and lower sides of the interior of the reversing reduction box, and the intermediate shaft and the output shaft are movably connected in the reversing reduction box via the bearings.

[0008] Preferably, the intermediate shaft and the output shaft are both located on the same central axis of the reversing reduction gearbox.

[0009] Preferably, the output end of the planetary reducer increases the torque and reduces the rotation speed through the intermediate reduction box.

[0010] Preferably, the reversing reduction box makes the directions of the two output shafts consistent and the torques of the output shafts the same.

[0011] The beneficial effects of the utility model are embodied in:

[0012] The utility model AGV trolley runs to the designated position, and the reducer drives the workbench to slowly rise or fall, and transports the materials to the designated height. The servo motor provides power, and the two output shafts drive the platform to rise and fall. The output torques of the output shafts are the same in magnitude and direction. The planetary reducer increases the torque and reduces the rotation speed through the intermediate reducer box, and then makes the directions of the two output shafts consistent through the reversing reducer box, the torques are the same in magnitude, the precision is high, and the platform is lifted and lowered smoothly. Since the two output shafts are driven by the same reducer, there is no angle error and installation error, and the lifting height is kept consistent; the cost is low, and the original two reducers are changed into one reducer with high strength; the gears adopt an integrated molding process; the overall carburization increases the strength and wear resistance of the gears.

The two output shafts drive the platform to rise and fall. The output torque of the output shafts is the same in size and direction. A plurality of intermediate shafts 6 are evenly arranged between the output shafts 1 in the reversing reducer 3. The middle end periphery of the intermediate shaft 6 is fixedly installed with gears 7. A plurality of bearings 5 ​​are arranged at both ends of the intermediate shaft 6 in the reversing reducer 3. The platform rises and falls smoothly. Since the two output shafts are driven by the same reducer, there is no angle error and installation error, and the lifting height remains consistent.
