Description

Technical Field

[0001] The utility model relates to the technical field of spindle transmission of horizontal milling and boring machines, in particular to a spindle transmission mechanism of a horizontal milling and boring machine. Background Art

[0002] The main transmission system of the horizontal milling and boring machine is used to realize the main movement of the machine tool. It is one of the forming movements of the machine tool. It converts the original power of the spindle motor into cutting torque and cutting speed that can be used for cutting processing through the transmission system. The main transmission system of the horizontal milling and boring machine is a very important part of the machine tool.

[0003] After searching, it is found that the spindle transmission mechanism of the horizontal milling and boring machine in the prior art usually uses a gear set to achieve deceleration. In order to reduce friction and increase the life of the gear set, it is usually necessary to apply lubricating oil to the gear set. During high-speed operation, the friction between the gears is likely to generate a large amount of metal debris. In order to prevent the metal debris in the lubricating oil from wearing the gear set while lubricating the gear set, thereby affecting the service life, a filter is usually configured and the lubricating oil is allowed to circulate. However, since the filter cannot be actively cleaned, the metal debris accumulates on one side of the filter. When there are too many metal debris, the filter will be blocked. The poor circulation of the lubricating oil causes the metal debris to easily stay near the gear set, affecting the service life of the gear set. Utility Model Content
