Description

Technical Field

[0001] This utility model relates to the field of automation, and in particular to a hollow planetary reducer. Background Art

[0002] The function of hollow planetary reducers is to achieve their application effects in different scenarios by rapidly cooling, sealing and preventing corrosion, and waterproofing and moisture-proofing the hollow planetary reducers.

[0003] Existing hollow planetary reducers achieve bidirectional transmission of the central shaft by splicing the planetary reduction mechanism with the outer surface of the motor. While convenient in design, they cannot adapt to various working scenarios. They lack improvements in corrosion resistance, waterproofing, heat dissipation, and impact protection, resulting in a short service life. For example, a Chinese patent discloses a "hollow planetary reducer" with application number "CN202222551892.7," which achieves reduction by splicing the motor and planetary reduction mechanism together, without considering the equipment's requirements for different working conditions. Its applicability is narrow, and its performance cannot be guaranteed. Utility Model Content
