Transmission shaft of die head threading machine

Abstract

The invention discloses a transmission shaft of a die head threading machine. The transmission shaft is applicable to the working state of continuous oil supply and comprises a shaft head cover with which a main shaft is covered. The main shaft is connected with a bearing gear. The transmission shaft is characterized in that an injected oil containing cavity is formed in the joint of the bearing gear and the main shaft, an oil outlet hole of the injected oil containing cavity is close to the outer surface of the main shaft, and the bearing gear is provided with at least one oil inlet cavity communicated with the injected oil containing cavity. According to the technical scheme, the surface of the main shaft can be sufficiently coated with lubrication oil, and centrifugal lubrication oil can be recycled and reused.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a transmission shaft of a threading machine. Background technique [0002] At present, in building construction, the connection method between steel bars is mechanical connection, and a threading machine is required for processing between two steel bars. During the process of processing steel bars through the threading machine, the transmission shaft of the threading machine will Continuous work, on the one hand, will continue to generate heat energy, and on the other hand, it will cause the lack of lubricating oil. Therefore, it is necessary to stop the threading machine at intervals to cool the drive shaft and add lubricating oil. [0003] In the prior art, there is a technical solution to automatically add lubricating oil without stopping the threading machine, but it stores the lubricating oil in advance, and when the lubricating oil is added to the transmission shaft,...

[0002] At present, in building construction, the connection method between steel bars is mechanical connection, and a threading machine is required for processing between two steel bars. During the process of processing steel bars through the threading machine, the transmission shaft of the threading machine will Continuous work, on the one hand, will continue to generate heat, on the other hand, it will lead to the lack of lubricating oil, so stop the threading machine at intervals to cool the drive shaft and add lubricating oil

[0003] In the prior art, there is a technical solution to automatically add lubricating oil without stopping the threading machine, but it stores the lubricating oil in advance, and when the lubricating oil is added to the transmission shaft, the transmission shaft rotates at a high speed, which will The oil is centrifuged to the housing, causing a lot of waste, and the lubricating oil cannot be well coated on the surface of the drive shaft
