[0002] At present, the transmission side of the electronic shaft driven gravure printing machine is no longer designed with an oil immersion box because of its gas movement and no gear meshing device. The two main bearings rely on the method of adding grease in the bearings to meet the lubrication requirements and extend the service life of the bearings.
[0003] The existing bearing lubrication device is prone to the following problems during use. First, the viscous grease generates heat due to the long-term operation of the bearing. The viscous grease becomes thinner due to the increase in temperature and flows out of the bearing. If grease is not added in time after long-term work, it is easy to cause bearing damage. Second, the lubricating oil at the bottom of the oil tank is easy to crystallize, resulting in low oil output efficiency and failure to output oil in time, which reduces the practicality of the lubrication device. Therefore, in response to the above problems, we proposed a lubrication device for the main bearing of the gravure printing machine transmission to the electronic axis. Utility Model Content

If the grease is not added in time after long-term operation, it is easy to cause damage to the bearing; second, the lubricating oil at the bottom of the oil tank is easy to crystallize, resulting in low oil output efficiency, and the oil cannot be output in time, which reduces the practicality of the lubrication device.
