Problems solved by technology

When an accident of damage to the pinion fixed end bearing occurs in the worm gear box, according to the conventional maintenance method, the maintenance personnel need to first remove the half-suspended left (or right) worm gear box as a whole, and then repair the pinion fixed end in the offline state. The repair of the bearing is time-consuming and labor-intensive, and it takes more than 48 hours to complete the repair work. However, the production task of the sintering machine is heavy, and the longer the downtime, the greater the loss of the enterprise. Therefore, it is necessary to propose a fixed pinion that can be replaced online. End bearing tools and methods that greatly reduce downtime for repairs

Embodiment 1

[0037] The dismantling tool for the fixed end of the bolt-connected worm gear pinion, including the ring gear pressure rod 3 supported on the worm gear box 2 and pushing out the worm gear ring gear 21, and the pulling hub device 4 for pulling out the worm gear hub 22;

[0038] The ring gear pressing rod 3 comprises a pressing rod main body 31, two screw rods 32 which are screwed in the horizontal direction at both ends of the pressing rod main body 31, and a pressing rod which is threaded in the vertical direction in the middle of the pressing rod main body 31 and is used to eject the worm gear ring gear 21. Rod screw 33, screw rod 32 is rotatably connected with an inner arc support block 34 for supporting in the worm gear box 2 at one end away from the pressure rod main body 31, the inner arc support block 34 is a permanent magnet, and the outer arc support block 34 The side is a rough friction surface, which is conducive to the fixing of the ring gear pressure rod 3 in the wo...

Embodiment 2

[0041] Such as Figure 4-5As shown, on the basis of Embodiment 1, a pressing plate 35 is provided at the end of the pressing bar screw 33 of the ring gear pressing bar 3 close to the worm gear ring gear 21, and the pressing plate 35 is rotatably connected with the pressing bar screw 33, and the pressing plate 35 is connected to the worm gear Contact with ring 21, increase the force bearing area, avoid the surface of the worm gear ring 21 from being scratched by the pressure rod screw 33, and because the pressure plate 35 is rotatably connected with the pressure rod screw 33, the resistance to rotation of the pressure rod screw 33 is greatly reduced; Such as Figure 6 As shown, on the basis of Embodiment 1, a top plate 44 is provided at one end of the top shaft screw 43 of the pull hub device 4 close to the pinion shaft 13, and the top plate 44 is rotatably connected with the top shaft screw 43, and the top plate 44 is connected to the top shaft screw 43. The pinion shaft 13 c...

Abstract

The invention provides a dismantling tool for the fixed end of the pinion of a bolt-connected worm gear, including a ring gear pressing rod and a pulling hub device, and the invention also provides a bolt-connecting worm gear using the ring gear pressing rod and a pulling hub device The method of online replacement of the fixed end of the pinion is to separate the worm wheel ring gear from the worm wheel hub through the gear lever, take out the worm wheel hub by pulling the hub device, and then take out the worm gear ring gear, thereby exposing the pinion fixed end bearing cover, realizing On-line replacement of pinion fixed-end bearings, the invention meets the assembly technical requirements of the flexible transmission device, does not need to dismantle the worm gear box as a whole, can realize on-line maintenance, greatly reduces downtime, and improves the effective operation rate of the sintering machine. The tools and methods of the invention can also be applied to online replacement of bearings or gears for equipment of the same type of structure, so as to improve maintenance efficiency.

Description

technical field [0001] The invention relates to a maintenance method of a flexible transmission device, more specifically, it relates to a dismantling tool and an on-line replacement method for the fixed end of a bolt-connected worm wheel and pinion. Background technique [0002] In the flexible transmission device, the worm gear box body is usually designed in an integrated structure. The normal assembly process is to first assemble the pinion shaft to the worm gear box, then assemble the worm wheel to the pinion shaft, and then assemble the worm As far as the worm gear box is concerned, taking the sintering machine as an example, the power input of the star wheel at the head of the sintering machine adopts a multi-point meshing flexible transmission device, which is divided into left type and right type, which can adapt to the transmission layout of the sintering machine. When an accident of damage to the pinion fixed end bearing occurs in the worm gear box, according to t...
