Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1, 2 and 3, the present invention provides a single-stage worm gear with a lubrication structure, which comprises: the structure of the worm gear box comprises a box body 1, a worm 2 and a worm wheel 3, wherein the worm 2 and the worm wheel 3 are arranged in the box body 1, the worm wheel 3 is connected with the worm 2 in a meshing manner, the worm gear box also comprises a lubricating structure for maintaining and lubricating the worm 2, the lubricating structure comprises a compression column 5 and a lubricating block 6, the compression column 5 movably penetrates through the upper end of the box body 1, the lubricating block 6 is arranged between the worm 2 and the inner wall of the box body 1 and is connected with the compression column 5, the outer wall of the compression column 5 is provided with a chute 7, the box body 1 is provided with a limiting block 8 matched with the chute 7, a spring 9 is arranged between the limiting block 8 and the inner wall of the chute 7, the center of the compression column 5 is provided with an oil filling channel 10, a small check valve 11 is arranged in the oil filling channel 10, the bottom of the lubricating block 6 is of an arc structure, the, one end of the flow channel 13 is connected with the brush block 12, the other end of the flow channel is communicated with the oil injection channel 10, the length of the lubricating block 6 is larger than or equal to that of the thread structure on the worm 2, one end of the worm 2 penetrates out of the box body 1 and is connected with the hand wheel 4, and the end part of the compression column 5 is provided with a disc-shaped pressing structure.

For example, when maintenance lubrication needs to be carried out, a proper amount of maintenance lubricating liquid is injected into the oil injection channel 10, the small check valve 11 plays a role in preventing backflow, the maintenance lubricating liquid flows into the flow channel 13 through the oil injection channel 10, and then flows onto the brush block 12 through the flow channel 13, because the maintenance lubricating liquid has viscosity, the maintenance lubricating liquid can be adhered to the brush block 12, a worker only needs to press the compression leg 5, so that the compression leg 5 drives the lubricating block 6 to be in contact with the thread structure of the worm 2, the hand wheel 4 is rotated to carry out opening and closing work, along with the rotation of the worm 2, the maintenance lubricating liquid on the brush block 12 is uniformly coated on the worm 2, the worm 2 drives the worm wheel 3 to rotate, the maintenance lubricating liquid is transferred, and the lubrication work is completed.
