AI Technical Summary
The high temperature inside the flywheel structure causes the lubricating oil to expand, which increases the pressure on the sealing components and increases the risk of leakage.
A self-adjusting pressure relief valve structure is designed, which includes a steel ball, a spring and a channel. The expansion pressure of the lubricating oil is used to push the steel ball to move, automatically discharging excess lubricating oil to avoid pressure increase in the sealing components.
Automatic pressure relief is achieved without manual adjustment, which reduces the pressure on sealing components and reduces the risk of leakage.

[0015] like Figure 1-3 As shown, this specific embodiment is a flywheel structure suitable for a plum blossom line dropping machine, comprising a rotating shaft 1, a bearing 2, a flywheel body 3, and a gasket 4. The bearing 2 is sleeved on the rotating shaft 1, the gasket 4 is sleeved on the bearing 2, the flywheel body 3 is sleeved on the end of the rotating shaft 1, and is connected to the gasket 4. A groove 31 is provided on the inner surface of the flywheel body 3 that abuts the bearing 2, and it is characterized in that it also includes a pressure relief valve 5 connected to the groove 31, the pressure relief valve 5 is used to discharge the lubricating oil that expands due to heat, the pressure relief valve 5 includes a steel ball 51, a spring 52, and a channel for guiding the lubricating oil to flow out, the steel ball 51 and the spring 52 are constrained in the channel, the channel has a first end 53b connected to the groove 31, the steel ball 51 is located between the above-mentioned first end 53b and the spring 52, and is abutted against the above-mentioned first end 53b through the spring 52, for blocking the lubricating oil from flowing out of the groove 31.
[0016] The utility model designs a pressure relief valve structure. The pressure relief valve 5 is a self-starting pressure relief valve and does not require manual adjustment. The pressure relief valve 5 is composed of a spring 52, a steel ball 51 and a channel. After the lubricating oil expands due to heat, the pressure on the groove 31 directly pushes the steel ball 51 to move, and the lubricating oil flows out of the channel, thereby solving the problem of high pressure on other sealing components.
[0017] Furthermore, the flywheel body 3 includes a bearing cover 32 and a flywheel 33. The central area of the flywheel 33 is a mounting port. The bearing cover 32 is arranged in the mounting port and is connected to the gasket 4. A channel is provided on the bearing cover 32. The channel is relatively vertical and passes through the inner and outer surfaces of the bearing cover 32. The outer end face of the flywheel 33 is facing downward. Therefore, when the bearing cover 32 is assembled to the mounting port, the bearing cover 32 is horizontal. By providing a channel on the bearing cover 32, the influence of gravity can be utilized to allow the lubricating oil to leak out in a vertical form. This method will not allow the lubricating liquid to remain in the channel.
[0018] Furthermore, the first end 53b is an inverted cone structure, the purpose of which is to constrain the steel ball 51. Under the action of the spring 52, the steel ball 51 will only block the lubricating liquid from flowing into the channel, and will not allow the steel ball 51 to escape from the channel.
[0019] Furthermore, the channel has a second end 53c opposite to the first end 53b and a middle area 53a, and the spring 52 is arranged in the middle area 53a. The width of the second end 53c is smaller than the diameter of the spring 52; its purpose is also to restrain the spring 52 and prevent the spring 52 from escaping from the channel. In this way, the lubricating fluid in the channel will only be discharged through the second end 53c, and the spring 52 is positioned in the middle area 53a.
[0020] Furthermore, it also includes fixing screws, and the bearing cover 32 is connected to the gasket 4 through the fixing screws to enhance the stability of the connection between the two.
[0021] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
