Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of gear ring, concretely is a detachable gear ring. BACKGROUND

[0002] In modern industry and mechanical equipment, gear transmission system is an important part of realizing mechanical power transmission, and is widely used in automobiles, aviation, heavy machinery and various power transmission equipment. The traditional gear ring is generally integrally machined and fixed with the base as a whole. Although this design ensures the stability of the gear ring, it has many shortcomings in practical application. When the gear ring needs to be replaced due to wear or damage, the gear ring often cannot be replaced alone, and the entire assembly must be replaced. This not only leads to waste of materials, but also significantly increases the use and maintenance cost.

[0003] The patent with publication number CN220337418U discloses a detachable gear ring for automobile, which comprises a plurality of half gear rings arranged in a ring shape at equal intervals, a mounting ring fixed at the middle of the inner side of the plurality of half gear rings, and a fixing assembly provided on the front surface of the inner side of the plurality of half gear rings for fixing two half gear rings. The fixing assembly comprises a fixing seat fixedly connected to the front surface of the inner side of the half gear ring, a fixing block movably connected to one end of the fixing seat, and a fixing groove formed at the other end of the fixing seat. By inserting the fixing block of one half gear ring into the fixing groove of another half gear ring, the plurality of half gear rings can be connected end to end. By inserting a bolt into the second and third bolt grooves, the two half gear rings can be fixed, and the plurality of half gear rings can be connected and fixed into a complete gear ring. When a part of the gear ring is worn, the corresponding half gear ring can be disassembled and replaced, thereby completing the maintenance work of the gear ring, reducing the maintenance cost, and saving materials.

[0004] The above-mentioned prior art realizes the detachable replacement of the gear ring by combining a plurality of half gear rings. Specifically, the plurality of half gear rings are arranged in a ring shape at equal intervals, the inner side is fixed by the mounting ring, and the adjacent half gear rings are fixed by the fixing assembly. However, this design still has some shortcomings in actual operation. First, when the two adjacent fixing assemblies are connected, the fixing block on one fixing seat needs to be inserted into the fixing groove on the other fixing seat, and the fixing block is fixed in the fixing groove by a bolt. This means that when one fixing assembly needs to be disassembled, the bolts of the fixing assembly and the adjacent fixing assembly must be disassembled, resulting in a complicated disassembly process and failing to realize the convenient replacement of a single half gear ring. In addition, the fixing seat of the fixing assembly forms a large hollow structure after connection, which reduces the overall strength and poses a safety hazard. Therefore, we propose a detachable gear ring. UTILITY MODEL CONTENTS
