The working principle is as follows: the adjustable precision SPN type planetary gear reducer connects the input shaft 2 to the output end of the external motor when in use, the position of the installation barrel 1 is fixed to enable the filter box 5 on the installation barrel 1 to be positioned at the lower position, when the input shaft 2 rotates, the driving gear 21 fixedly connected to the input shaft 2 rotates, and then the driven gear 22 meshed with the driving gear 21 rotates, because the driven gear 22 is meshed with the annular teeth 11 in the installation barrel 1, and then the driving gear 21 drives the driven gear 22 to rotate, the driven gear 22 can revolve around the driving gear 21 in the installation barrel 1, because the rotating shaft 14 fixedly connected to the driven gear 22 revolves around the driven gear 22, and two ends of the rotating shaft 14 respectively rotate on the annular ring 12 and the planet carrier 13 in a fixed-axis manner, and then the annular ring 12 and the planet carrier 13 can be driven by the three revolving rotating shafts 14 to rotate around the axis of the installation barrel 1, and the output shaft 3 connected to the carrier 13 rotates, so that the rotation speed of the output shaft 3 is reduced while the torque is increased.
When the circular ring 12 rotates, the arc-shaped block 121 fixedly connected to the circular ring 12 rotates synchronously with the circular ring 12, the arc-shaped block 121 alternately contacts with the first piston rod 45 and the elliptical block 65, when the arc-shaped block 121 contacts with the first piston rod 45, the bottom of the first piston rod 45 can move upwards along the track of the arc-shaped block 121, then the piston plate 451 fixedly connected to the first piston rod 45 moves upwards in the first piston cylinder 4, when the arc-shaped block 121 gradually leaves away from the first piston rod 45, the first piston plate 451 is pushed to slide downwards in the first piston cylinder 4 under the action of the first spring 452, the circular ring 12 rotates for a circle, so that the piston plate 451 slides in the first piston cylinder 4 in a reciprocating manner once, then the first piston cylinder 4 extracts the engine oil in the mounting cylinder 1 through the oil extraction pipe 43, then the extracted engine oil is injected into the mounting cylinder 1 again through the oil injection pipe 42, and the engine oil can flow, the spare part to in the installation section of thick bamboo 1 is cooled down lubricated, and the machine oil in the installation section of thick bamboo 1 passes through rose box 5 when being extracted through oil extraction pipe 43 simultaneously for the metal fillings that the spare part when moving in the installation section of thick bamboo 1 abraded down are filtered by filter screen 51 in the rose box 5, avoid the spare part wearing and tearing aggravation in the installation section of thick bamboo 1.
When the arc-shaped block 121 on the circular ring 12 contacts the elliptical block 65 and continues to move, the elliptical block 65 is pressed along the arc-shaped track of the arc-shaped block 121 to move downward, at this time, the vertical rod 651 fixedly connected to the bottom of the elliptical block 65 and the elliptical block 65 move downward synchronously, and then the vertical rod 651 moving downward pushes the inclined rod 652 to swing downward with the connecting rod 653 as a center of a circle, and then the two second piston rods 654 fixedly connected to the connecting rod 653 slide toward the corresponding second piston cylinders 61, and after the arc-shaped block 121 is far away from the elliptical block 65, the vertical rod 651 does not bear downward force any more, so that the inclined rod 652 does not bear pressure from the vertical rod 651, and further the second piston rods 654 do not bear thrust from the inclined rod 652 any more, at this time, the second piston rods 654 slide out of the second piston cylinders 61 under the action of the fourth springs 611, and then the elliptical block 65 returns to the original position, in conclusion, the pressing of the arc-shaped block 121 on the circular ring 12 on the elliptical block 65 can make the second piston rods 654 slide in a reciprocating manner in the second piston cylinders 61 The second piston cylinder 61 is moved to pump the hydraulic oil in the box body 6 into the second piston cylinder 61 through the first pipeline 64, then the pumped hydraulic oil in the second piston cylinder 61 is transmitted into the hydraulic rod 37 through the second pipeline 62, and then the output end of the hydraulic rod 37 extends out to extrude the tripod 35, so that the tripod 35 applies pressure to the press ring 32, the ball 33 on the press ring 32 can be tightly attached to the circular table block 31 on the output shaft 3, and because the press ring 32 and the mounting cylinder 1 are positioned on the same axis, the extrusion of the press ring 32 on the circular table block 31 can keep the coaxiality of the output shaft 3 and the mounting cylinder 1, and the output precision of the output shaft 3 is improved;
when the hydraulic rod 37 is fully filled with hydraulic oil, the hydraulic rod 37 does not extend any more, at this time, the second piston cylinder 61 still conveys hydraulic oil to the hydraulic rod 37 through the second pipeline 62, so that the pressure in the second pipeline 62 is increased, when the pressure in the second pipeline 62 is increased to a critical value set by the pressure valve 622, the pressure valve 622 is opened, so that the hydraulic oil in the pressure relief pipe 621 flows, and impacts the rotating plate 662 in the hollow column 66, so that the cylindrical cam 661 rotates, and the vane 663 fixedly connected to the cylindrical cam 661 rotates to blow the filter box 5, so that the engine oil flowing through the filter box 5 can be cooled;
when the cylindrical cam 661 rotates, the convex balls 522 on the collar 521 can slide relatively relative to the sliding grooves on the cylindrical cam 661 because the cylindrical cam 661 rotates on the filtering box 5 in a fixed shaft mode, the scraper 52 is connected to the filtering box 5 in a sliding mode, the collar 521 is fixedly connected to the scraper 52, further the collar 521 can slide axially and reciprocally on the cylindrical cam 661 due to the rotation of the cylindrical cam 661, further the scraper 52 fixedly connected with the collar 521 also slides axially and reciprocally, the scraper 52 is attached to the filter screen 51, and then the scraper 52 which slides axially and reciprocally along with the collar 521 can scrape metal scraps on the filter screen 51;
meanwhile, the scraping plate 52 gradually approaches the blocking block 53 and presses the blocking block 53, so that the blocking block 53 can slide in a direction away from the filter box 5 against the elastic force of the third spring 534, then the scraping plate 52 pushes the metal chips scraped from the filter screen 51 to the outside of the filter box 5, meanwhile, the blocking block 53 can contact the pressure sensitive switch 542 when being pushed by the scraping plate 52, so that the electromagnet 54 is opened, the scraped metal chips are attracted by the electromagnet 54 and separated from the scraping plate 52, when the scraping plate 52 slides in the direction away from the blocking block 53, the blocking block 53 continues to block the filter box 5 under the action of the third spring 534, meanwhile, the blocking block 53 is not in contact with the pressure sensitive switch 542 any more, so that the electromagnet 54 is not electrified and magnetic any more, and then the metal chips adsorbed by the electromagnet 54 fall onto the sloping plate 535 and slide down along the sloping plate 535, and meanwhile, when the scraping plate 52 slides in the filter box 5, the filter box 5 can generate slight vibration, and the sloping plate 535 on the filter box 5 is vibrated, so that the metal chips on the sloping plate 535 slide off more easily and cannot be sucked up by the electromagnet 54.
