Description

Technical Field

[0001] The utility model relates to the technical field of speed reducers, in particular to an integrated lubrication system for a dual-shaft speed reducer. Background Art

[0002] In the field of mechanical transmission, reducers, as a common power transmission and speed regulation device, are widely used in various industrial equipment and mechanical systems. The performance stability and service life of a reducer depend largely on the lubrication of its internal components, particularly the bearings at the shaft entry. Bearing lubrication, a key component in a reducer, directly impacts its operating efficiency and durability. Traditionally, grease is used to lubricate the shaft entry of a reducer. Grease has excellent adhesion and sealing properties, ensuring a certain degree of bearing lubrication. However, in actual use, this lubrication method has gradually exposed some limitations, especially in applications where the reducer requires frequent adjustment of the installation angle.

[0003] Due to the diversity of customer needs, reducers often need to be installed at a variety of angles and positions. This frequent adjustment of the installation angle often makes it difficult to fully and evenly lubricate the bearings at the shaft entry point. Especially at certain extreme angles, the grease may be unevenly distributed due to gravity, or even completely missing in some areas, resulting in increased localized wear on the bearings and affecting the overall performance of the reducer. In addition, the replacement and maintenance of traditional grease are also quite difficult. As the reducer's operating time increases, the grease gradually ages and deteriorates, losing its original lubricating properties. However, due to the complexity of the reducer's structure and the limitations of on-site conditions, customers often find it difficult to disassemble and repair the reducer to replace the aged grease. This not only increases the maintenance cost of the reducer but also seriously affects its service life and reliability. Summary of the Invention
