Description

Technical Field

[0001] The utility model relates to the technical field of bevel gear production, in particular to a bevel gear meshing degree detection device. Background Art

[0002] Gears are mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. They are mechanical parts with teeth that can mesh with each other. The diameter of the large gear is twice the diameter of the small gear. The meshing connection between gears can achieve a series transmission effect, but the meshing connection with gaps will not only affect the meshing connection stability between gears under long-term high-speed operation, but also cause the gears to fall off, so meshing inspection is required before use.

[0003] After searching the Chinese patent with announcement number CN216207544U, a gear meshing degree detection device is disclosed. The gear meshing degree detection work is completed through the cooperation of the limit gear and the adjustment gear. Compared with the conventional single gear detection method, the detection accuracy is greatly improved. The drive motor is always in a low-speed operation state during the actual detection process to protect the mechanical structure of the gear to be tested.

[0004] Based on the above search and combined with the prior art, it is found that: before and after the bevel gear inspection process, it is inconvenient to disassemble, assemble and replace the bevel gears after inspection, the meshing degree of multiple bevel gears cannot be inspected at the same time, and one group of bevel gears cannot be replaced while another group of bevel gears are being inspected, resulting in a long pause in the replacement process, which reduces the inspection efficiency of the bevel gears. Utility Model Content

[0005] The purpose of the utility model is to provide a bevel gear meshing degree detection device to solve the problems raised in the above-mentioned background technology. By setting up a rotation of two groups of bevel gears to be tested, one group of bevel gears can be replaced by the other group of bevel gears that have been tested when being tested. The two can perform the detection structure synchronously without long pauses to speed up the detection speed, and multiple bevel gears can be tested and processed at the same time.

[0013] First, the utility model is provided with a base, a cylinder, a motor 1, a motor 2, a support plate, a hydraulic rod and a transmission wheel group. The motor 1 drives the three worms to rotate through the transmission wheel group, thereby driving the movable rod to rotate through the worm gear, so that one end of the support plate installed with the bevel gear to be tested is moved downward close to the detection gear at the bottom of the cylinder. The hydraulic rod pushes out the support plate, so that the bevel gear to be tested is meshed with the tooth pattern of the detection gear. At this time, the motor 2 drives the detection gear to rotate, thereby driving multiple bevel gears to be tested to rotate together to detect the meshing degree. At the same time, a new bevel gear to be tested is installed in the sliding tube at the top of the support plate.
