In order to avoid when the output shaft is in the long-time rotatory in-process, because collide vibrations and lead to the sealing washer not hard up influence the leakproofness, perhaps appear not hard up influence the leakproofness after the sealing washer ages. And the sealing effect, and thus the oil leakage preventing effect, can be further improved by pressing the second housing 22 with the plurality of pressing plates 57.
When the knob 415 drives one positioning mechanism 1 to move, the linkage assembly 4 is utilized to drive the leakage prevention mechanism 5 to start to operate, and at the moment, the linkage assembly 4 is utilized to drive a plurality of other positioning mechanisms 1 to move when a plurality of movable rods 55 on the leakage prevention mechanism 5 move together, so that the synchronous movement of the positioning mechanisms 1 is completed, the positioning of the first shell 21 and the second shell 22 is completed, the connection firmness is improved, and the connection looseness caused by collision and vibration is avoided.
The application method and the working principle of the device are as follows: the anti-leakage mechanism 5 is sleeved on the outer surface of the shaft end at one side of the second shell 22, and the outer surface of the shaft end at the side of the second shell 22 is sleeved on the surface of the output shaft of the speed reducer 2, so that the anti-leakage mechanism 5 can squeeze and position a sealing ring at the position, and the phenomenon that the sealing ring is loosened after aging occurs due to long-term use, so that the sealing performance is reduced can be avoided; during installation, the bottom plate 51 may be fixedly attached to the second housing 22 by a number of fasteners.
Then, the two arc-shaped mounting plates 3 are mounted on the surface of the second housing 22 through fasteners, and in the mounting process, the limiting frame 47 on the linkage assembly 4 is also clamped with one side of the second housing 22 on the outer surface of the second housing 22, and then is connected with the second housing 22 through a fixing screw 471. In the installation process, the plugging rod 462 at the bottom end of the control rod 46 is aligned with the plugging groove 553 at one end of the movable rod 55, the positioning rod 555 passes through the calibration hole 554 and then is connected with the positioning groove 461, and in the connection process, the positioning rod 555 is respectively connected with the calibration hole 554 and the positioning groove 461 through threads, so that the connection firmness of the movable rod 55 and the control rod 46 can be improved.
In addition, although there are a plurality of linkage assemblies 4, only one side of the linkage assembly 4 is connected with the fixed plate 41, at this time, the knob 415 on one side of the fixed plate 41 is screwed to drive the driving bevel gear 414 to rotate, when the driving bevel gear 414 rotates, the driven bevel gear 413 is also driven to rotate, at this time, the screw rod 411 starts to rotate under the driving of the driven bevel gear 413, so that the sliding block 412 on the surface of the screw rod 411 starts to move, and when the sliding block 412 moves, the connecting block 42 on one linkage assembly 4 is also driven to move, so that the moving rod 15 is driven to move by the connecting block 42. The connecting block 42 also utilizes the first linkage rod 44 at the top end of the fixed rod 43 to drive the control rod 46 to move, and in this process, the two second linkage rods 45 also drive the control rod 46 to move together, at this time, the control rod 46 slides up and down under the limitation of the limiting frame 47, so that the control rod 46 drives the movable rod 55 to move up and down together, and when the movable rod 55 moves up and down, the rack 552 is driven to move, so as to drive the driving gear 54 at one side of the rack 552 to rotate.
Therefore, according to the rotation direction of the knob 415, the moving direction of the moving rod 15 is further controlled, so that the moving rod 15 is controlled to drive the clamping plate 14 to move towards the annular plate on one side of the first housing 21, when the moving rod 15 moves, the moving rod will move in the movable groove 131 inside the mounting block 13, when the moving rod 15 starts to move vertically downwards, and the top section width of the moving rod 15 is larger than the bottom section width, so that the moving rod 15 will gradually apply the extrusion force to the limit roller 162 by using the top end of the moving rod, and the movement of the moving rod 15 is estimated to be vertically downwards, so that the limit roller 162 is converted into a transverse pushing force when the extrusion force is received, and the limit roller 162 starts to move rightwards. Also, since the limit roller 162 is installed in the through hole 163 of the extension block 16, when the limit roller 162 is moved, it moves together with the extension block 16, so that one end of the extension block 16 gradually protrudes from the inside of the installation block 13.
In addition, the limit roller 162 is rotationally connected with the inner wall of the through hole 163, so that when the limit roller 162 is pushed to move by the moving rod 15, the limit roller 162 can rotate, friction force generated when the limit roller 162 is pushed by the moving rod 15 can be reduced, and further the moving rod 15 is pushed by the moving rod 162, so that the moving rod 15 is prevented from being severely worn due to friction force.
In this process, the limiting groove 151 moves relative to the limiting block 161, and as the moving rod 15 moves downward, the limiting groove 151 generates a pushing force on the limiting block 161, so that the limiting block 161 drives the extension block 16 to move. Therefore, when the moving rod 15 moves downwards, the extending block 16 is driven to move together by the limiting block 161 and the limiting roller 162, and the two annular plates at the joint of the first housing 21 and the second housing 22 are clamped by the matching clamping plate 14 along with the extending block 16 extending. After one positioning mechanism 1 starts to move, the leakage-proof mechanism 5 and the linkage assembly 4 drive the positioning mechanisms 1 to move together, so that the plurality of positioning mechanisms 1 can clamp and position the joint of the first shell 21 and the second shell 22 at the same time.
Then, the driving gear 54 rotates to drive the toothed ring 58, so that the toothed ring 58 drives the other gears to rotate together during rotation, and therefore, the other gears drive the other movable rods 55 to move together by the rack 552 during rotation, so that the movable rods 55 move together and all move towards a center of a circle, and the movable rods 55 squeeze the outer surface of one axial end of the second housing 22 by the squeeze plate 57 at one end.
Finally, when the knob 415 is adjusted, after one positioning mechanism 1 is driven to move, the clamping plate 14 and the extension block 16 on the positioning mechanism 1 are utilized to clamp two annular plates at the joint of the first shell 21 and the second shell 22, the anti-leakage mechanism 5 can also be driven to move, and the positioning mechanisms 1 of other mechanisms can be driven to start to move by utilizing the plurality of movable rods 55, the driving gears 54 and the toothed rings 58 arranged on the anti-leakage mechanism 5, so that the plurality of positioning mechanisms 1 and the anti-leakage mechanism 5 can move together, and the positioning of the first shell 21 and the second shell 22 on the surface of the speed reducer 2 is completed.
In addition, although the whole knob 415 is adopted to control the plurality of components to move together, the adjustment difficulty is possibly caused to be large, so that the adjustment can be performed through external tools such as a spanner, the situation that the knob 415 rotates randomly in the use process can be avoided, and the positioning effect and the leakage-proof effect are reduced.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
