Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to an integrated output shaft and ring gear reducer. Background Art

[0002] Planetary reducers are a widely used industrial product that can reduce motor speed while increasing output torque. They serve as supporting components in industries such as lifting, excavation, transportation, and construction. Their internal gears are made of carburized, quenched, and ground 20CrMnTi. They feature compact size, light weight, high load capacity, long service life, smooth operation, low noise, high output torque, a wide speed ratio, high efficiency, and safe performance. They also feature power splitting and unique multi-tooth meshing, making them a new type of reducer with broad versatility. The new planetary series includes the WGN fixed-axis transmission reducer, the WN parent-child gear transmission reducer, and the elastic load-sharing small-tooth-difference reducer, suitable for use in industries such as lifting and transportation, construction machinery, metallurgy, mining, petrochemicals, construction machinery, light industry and textiles, medical equipment, instrumentation, automotive, shipbuilding, weapons, and aerospace.

[0003] After searching, the publication number CN202320097331.6 is a low-speed planetary gear disassembly tool for an inner ring output type enclosed planetary gear reducer, which includes a gear ring and a planetary gear. The top of the gear ring is movably connected with a disassembly mechanism, which includes a handle, a threaded rod, a threaded sleeve, a support rod, a pull rod, a disassembly block, a baffle, and a first bearing. The inner ring output type enclosed planetary gear reducer low-speed planetary gear disassembly tool is provided with a disassembly mechanism. The disassembly block is inserted under the planetary gear, and then the support rod is held stationary and the handle is turned. The handle can drive The threaded rod rotates, and the threaded rod rotates inside the threaded sleeve, keeping the threaded sleeve stationary. The threaded rod can drive the baffle to move downward through the first bearing. When the baffle reaches above the gear ring, the gear ring can provide a reaction force to the baffle. Continuing to rotate the threaded rod can drive the threaded sleeve to move upward, and then drive the support rod to move upward, drive the pull rod to move upward, pull the disassembly block upward, pull the planetary gear upward, and complete the disassembly. This can not only prevent damage to the gear, but also save disassembly time and improve disassembly efficiency. The existing planetary reducer structure is not perfect and still has certain defects.
