Description

Technical Field

[0001] This utility model relates to the field of maintenance and repair technology of electromechanical equipment, specifically to a tool for removing the nylon rod of an LZZ type flexible pin gear coupling. Background Technology

[0002] Flexible pin couplings are mechanical parts used to connect two shafts in different devices to transmit rotational motion and torque. The coupling is divided into two halves, which are connected to the driving shaft and the driven shaft respectively. The two couplings are connected by nylon rod pins. When rotating, the nylon rod in the coupling is subjected to a large impact force, which can cause the nylon rod to break and the equipment to fail. According to the maintenance requirements of the coupling, the nylon rod needs to be removed regularly to check its wear.

[0003] Traditional methods for removing nylon rods involve using tools such as hammers and pry bars to remove them by hammering. Due to the limitations of the coupling structure and working space, most of these methods can only remove a portion of the nylon rods for inspection, and the removal is laborious, resulting in low efficiency for inspection and replacement. Utility Model Content

[0004] This utility model provides a tool for removing the nylon rod of an LZZ type elastic pin gear coupling, in order to solve the problems of laborious removal of the nylon rod and low efficiency of inspection and replacement during the removal process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tool for removing nylon rods from an LZZ type flexible pin-gear coupling includes symmetrically detachable semi-circular clamps. The semi-circular clamps are symmetrically and detachably connected to racks. The racks are engaged with limit rods, and a handle is rotatably provided at the connection between the limit rods and the racks. Multiple set screws are provided on the side of the semi-circular clamps.

[0007] Furthermore, the semi-circular clamp is symmetrically provided with rack bases, and racks are detachably and fixedly connected to the rack bases by rack bolts.

[0008] Furthermore, a bearing chamber is fixedly provided at one end of the limiting rod, and the bearing chamber and the handle are detachably connected by a cotter pin.

[0009] Furthermore, the bearing housing and the handle are fitted with gears, which mesh with the rack.

[0010] Furthermore, the semi-circular clamp is provided with a semi-circular clamp boss inside.

[0011] This utility model has the following beneficial effects:

[0012] In use, this utility model involves installing two semi-circular clamps on the first half-coupling, with the set screw corresponding to the nylon rod. A rack is installed inside the rack base, and the rack of the limiting rod passes under the gear and meshes with it. The other end of the limiting rod is secured to the second half-coupling. The handle passes through the bearing and gear in sequence, and its end is fixed by the handle limiting nut and cotter pin. Further, rotating the handle drives the gear, which in turn drives the rack, thereby moving the two semi-circular clamps and the set screw. Under the pressure of the set screw, the nylon rod disengages from the outside of the second half-coupling, achieving rapid disassembly of the nylon rod. This device has a simple structure, avoids the problem of limited working space, and relies on gear and rack meshing transmission to effectively achieve rapid disassembly of the nylon rod under the pressure of the set screw. Multiple nylon rods can be disassembled at once, reducing labor intensity and improving the efficiency of nylon rod disassembly. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-4As shown, an LZZ type elastic pin gear coupling nylon rod removal tool includes a symmetrically detachable semi-circular clamp 6, a rack 13 symmetrically and detachably connected to the semi-circular clamp 6, a limit rod 15 meshing with the rack 13, and a handle 19 rotatably provided at the connection between the limit rod 15 and the rack 13. The side of the semi-circular clamp 6 is provided with multiple set screws 11.

[0022] The semi-circular clamp 6 is symmetrically provided with rack bases 12, and racks 13 are detachably and fixedly connected to rack bases 12 by rack bolts 14.

[0023] One end of the limit rod 15 is fixedly provided with a bearing chamber 16, and the bearing chamber 16 and the handle 19 are detachably connected by a cotter pin 21.

[0024] A gear 18 is provided inside the bearing chamber 16 and the handle 19, and the gear 18 is meshed with the rack 13.

[0025] The semi-circular clamp 6 has a semi-circular clamp boss 10 inside.

[0026] A limiting groove 8 is provided on the side of the semi-circular clamp 6.

[0027] In practical use, the nylon rod baffle bolt 3 and nylon rod baffle 4 are disassembled, and then two semi-circular clamps 6 are symmetrically installed on the first half-coupling 1. The limiting groove 8 corresponds to the first half-coupling 1, and then the semi-circular clamp boss 10 is fixedly connected by bolt 9, so that the two semi-circular clamps 6 are fixedly connected. The set screw 11 is in corresponding contact with the nylon rod 5, and the rack 13 is fixedly connected to the rack base 12 by rack bolt 14. The rack 13 passes through the gear 18 from below and meshes with each other. The other end of the limiting pull rod 15 is stuck on the coupling brake wheel 7. The handle 19 passes through the bearing 17 and the gear 18 in sequence, and the end is rotated and fixed by the handle limiting nut 20 and the cotter pin 21. Then the handle 19 is rotated, the handle 19 drives the gear 18, the gear 18 drives the rack 13, thereby driving the two semi-circular clamps 6 and the set screw 11 to move. Under the pressure of the set screw 11, the nylon rod 5 is disengaged from the outside of the second half-coupling 2, realizing the quick disassembly of the nylon rod 5. The device has a simple structure, avoiding the problem of limited working space. It relies on the meshing transmission of gear 18 and rack 13 to effectively and quickly disassemble nylon rods 5 under the pressure of the set screw. Multiple nylon rods 5 can be disassembled at one time, reducing labor intensity and improving the disassembly efficiency of nylon rods 5.
