Description

Technical Field

[0001] The utility model belongs to the technical field of operating spanners, in particular to an operating tool for rotating a serpentine spring half coupling. Background Art

[0002] Many connection parts of large-scale port loading and unloading equipment are connected by JS series serpentine springs. Serpentine spring couplings are a kind of metal with advanced structure. It transmits torque by serpentine spring sheets. Serpentine spring couplings are the most advanced shaft connection transmission components in the international mechanical field today, and are also a very common shaft connection transmission component.

[0003] The main structure of the serpentine spring coupling is composed of two half couplings, two half covers, two sealing rings and serpentine spring sheets. It transmits torque by embedding the serpentine spring into the tooth grooves of the two half couplings. The coupling embeds the serpentine spring sheets into the tooth grooves of the two half couplings to achieve the connection between the driving shaft and the driven shaft. During operation, the driven end is driven by the axial force of the teeth of the driving end on the serpentine spring to transmit torque, which largely avoids the occurrence of resonance. The elastic variables generated by the spring sheets when transmitting torque enable the mechanical system to obtain a better vibration reduction effect, and the average vibration reduction rate is more than 36%.

[0004] The coupling has good flexibility and has advantages in concentricity correction. However, when the reduction box is replaced or repaired, the drive motor is disengaged. When rotation is required, it is entirely dependent on manual labor, which is time-consuming and labor-intensive, has low work efficiency, and also poses a safety hazard of personal injury. In order to eliminate the safety hazard, it is necessary to design a special rotation tool that can be assisted by an electric tool. Utility Model Content

[0005] In order to solve the problem that it is inconvenient and laborious to disassemble a coupling during replacement or maintenance, the utility model provides an operating tool for rotating a serpentine spring half coupling.

[0006] The utility model is realized by the following technical solutions:

[0007] An operating tool for rotating a serpentine spring half coupling comprises a base disc, one surface of which is provided with a snap-on group that can cooperate with a dividing circle on the half coupling; a connecting head is provided at the center of the other surface of the base disc, and the connecting head can cooperate with an external power source to drive the base disc to rotate.

[0008] With the base disc as support, the coupling group is connected with the pitch circle on the coupling. The external power source drives the disc to rotate through the connector, thereby realizing quick rotation of the coupling, effectively improving the convenience of operation and work efficiency, and avoiding potential safety hazards during manual rotation.

[0009] A further improvement of the utility model is that the above-mentioned clamping groups are provided in at least two groups, and the at least two clamping groups are equally arranged on the base disc to increase the contact points with the pitch circle.

[0010] A further improvement of the utility model is that the above-mentioned clamping group includes two driving claws, and the two driving claws are symmetrically arranged on the diameter line of the basic disc in a circle-centered manner.

[0011] A further improvement of the utility model is that the side of the driving claw facing the center of the circle is a tapered chamfered structure as a whole, which can be more accurately matched with the pitch circle and reduce the difficulty of adaptation and assembly.

[0012] A further improvement of the utility model is that a reinforcing rib is provided on the side of the driving claw away from the center of the circle to increase the structural strength of the driving claw on the base disc.

[0013] A further improvement of the utility model is that the connecting head is a hexagonal column that can be matched with a socket wrench.

[0014] A further improvement of the utility model is that the distance between opposite sides of the hexagonal column is 35 mm.

[0015] It can be seen from the above technical scheme that the beneficial effect of the utility model is: through the base disc as a support, the clamping group and the pitch circle on the coupling are matched and connected, and the external power source drives the disc to rotate through the connecting head, thereby realizing the quick rotation of the coupling, effectively improving the convenience of operation and work efficiency, and avoiding the safety hazards existing in the manual rotation process.
