This characteristic is crucial for precision machinery and instruments, and is also an important condition for reducing dynamic loads and achieving smooth transmission under high speed and heavy load.

[0003] When the gear and rack mesh, wear will be transmitted, so lubricating oil is usually added to the gear when it is used. However, if the lubricating oil is higher than the tooth surface for a long time, impurities will be deposited and cause excessive wear. Therefore, further improvement of the lubrication of the tooth surface is needed. Summary of the invention

[0010] In the above-mentioned novel gear transmission structure, a compression guide part is provided at the end of the guide tube, and a connecting rod is provided on the compression guide part.

[0011] Compared with the prior art, the novel gear transmission structure installs a compression injection unit by opening through grooves at both ends of the rack, and squeezes out the oil through contact and compression with the support part, and accelerates the compression through the compression guide part to form oil mist, so as to lubricate and cool the gear and rack. The compression injection units arranged in multiple places will trigger the compression injection units when the rack moves left and right, so that the lubrication is more sufficient.
