Description

Technical Field

[0001] This utility model relates to the technical field of drum-shaped gear couplings, specifically a radially disassembled gear coupling. Background Technology

[0002] A gear coupling consists of two half-couplings and an internal gear ring. Torque transmission between the two half-couplings is achieved through the meshing of the internal and external gears. Each half-coupling connects to a different rotating shaft, thus enabling torque transmission between the two drive shafts. Gear couplings are widely used in coal mining machinery due to their compact structure, high load-bearing capacity, and reliable operation. To limit the axial movement of the internal gear ring, two circular retaining rings are typically connected to it via axial bolts. This restricts the axial movement of the internal gear ring and ensures reliable torque transmission. However, this structure requires significant space at both ends of the coupling for disassembly and assembly, thus presenting certain limitations. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a radially disassembled gear coupling, which changes the axial bolt connection to a radial bolt connection, thereby solving the problem of difficulty in disassembling and assembling the coupling due to insufficient axial space, and can adapt to the narrow space of coal mine machinery and equipment.

The half retaining ring 21 is provided with an annular boss 211, surface A 212, and surface B 213. The annular boss 211 is fixed in conjunction with the left annular groove 11 and the right annular groove 52. The internal gear ring 3 has grooves 31 at both ends and an oil injection hole 32 in the middle. The inner ends are respectively provided with a left internal tooth 33 and a right internal tooth 34. The O-ring 4 is installed in the groove 31. The left drum-shaped tooth 12 meshes with the left internal tooth 33, and the right drum-shaped tooth 51 meshes with the right internal tooth 34. Surface B213 blocks the left and right sides of the internal gear ring 3 to prevent the internal gear ring 3 from moving axially. Surface A212 is located above the groove 31 and presses down on the O-ring 4 to prevent the oil injected from the oil injection hole 32 from flowing out of the gap.

It changes the traditional axial disassembly to radial disassembly, thereby solving the problem of difficulty in disassembling and assembling couplings caused by insufficient axial space.
