Example 3
This embodiment is based on the improvement of embodiment 1, referring to fig. 6, in order to smooth and extend the service life of the gear box, it is necessary to add lubricating oil into the box during use, the rotating frame 75 is provided with the isolation disc 9, the isolation disc 9 includes a first opening and a second opening, the isolation disc 9 gradually contracts along the direction from the first opening to the second opening, that is, a conical surface or an arc surface is formed on the outer surface from the first opening to the second opening, so that lubricating oil can flow to the sun gear 71, the planet gear 72 and the gear ring 73 along the surface for full lubrication, the outer edge of the first opening is connected with the rotating frame 75, so that the isolation disc 9 synchronously rotates along with the rotating frame 75, and the inner diameter of the second opening is not smaller than the root circle diameter of the second tooth, thereby not only preventing lubricating oil from entering the second tooth, but also preventing the second gear 79 from moving.
Second, the outer diameter of the second opening is not larger than the root diameter of the sun gear 71, ensuring that the lubricating oil can flow into the meshing of the sun gear 71 and the planet gears 72 for sufficient lubrication.
Further, the spacer 9 is provided with a limiting plane 91 towards the first gear 78, when the end surface of the first gear 78 near one side of the second gear 79 is abutted against the limiting plane 91, the first gear 78 is just inserted into the first tooth to form engagement, and the limiting plane 91 is matched with the upper pressure spring 701, the ball 702 and the adjusting bolt 703 to realize double positioning, so that the moving accuracy of the transmission shaft 77 is ensured.
Further, an extension rod 10 is disposed on a side, far away from the first gear 78, of the gear ring 73, the rotating frame 75 is L-shaped, and includes a cross rod portion coaxially disposed with the extension rod 10, and the cross sections of the extension rod 10 and the cross rod portion are diamond-shaped, so that when the extension rod and the cross rod portion follow the gear ring 73 to rotate, lubricating oil in the tank body can be stirred, and solidification of the lubricating oil is avoided. In addition, the extension rod 10 and the cross rod part can be in contact with the inner wall of the box body, so that lubricating oil is prevented from accumulating on the inner wall of the box body.
Example 4
This embodiment is a modification based on embodiment 1, referring to fig. 7, the rotating frame 75 is not in a rod shape in embodiment 1, but is changed into a shell shape, meanwhile, a sealing plate 11 is arranged on one side of the gear ring 73 far away from the rotating frame 75, the sealing plate 11 can be fixed relative to the connecting frame 74 or fixed relative to the box body 5, and a rotary sealing fit is formed between the sealing plate 11 and the gear ring 73, meanwhile, the sealing plate 11, the gear ring 73 and the rotating frame 75 form a sealing cavity 12, lubricating oil is contained in the sealing cavity 12, and when the gear ring 73 rotates, the sealing cavity 12 rotates correspondingly to follow the rotating of the sealing cavity, so that the lubricating oil in the sealing cavity can sufficiently lubricate the gear fit positions.
Secondly, because the volume of first gear 78 is greater than the volume of second gear 79, when carrying out quick switch to the valve, first gear 78 and first tooth meshing, the lubricating oil level in the sealed cavity 12 rises for each gear cooperation department fully lubricates, can make the quick switch of valve more smooth and easy, otherwise, when carrying out slow switch to the valve, second gear 79 and second tooth meshing, the lubricating oil level in the sealed cavity 12 descends.
The foregoing disclosure is illustrative of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
