Description

Technical Field

[0001] This utility model relates to the field of gear meshing error inspection technology, and specifically to a gear meshing error inspection device. Background Technology

[0002] A gear is a mechanical component that transmits motion and power through continuous meshing of gears on its rim. During the gear manufacturing process, it is generally necessary to detect the meshing error to ensure stable transmission between gears.

[0003] In the prior art, patent document CN220751603U discloses a gear meshing detection device, relating to the field of gear meshing detection technology. The device includes a base with a rectangular groove on its top and a square cavity inside. In use, pressing a rotating sleeve towards the base causes the rotating sleeve to move, simultaneously squeezing a rectangular plate towards the base. This causes two limiting racks to move in opposite directions under the limiting action of a guide unit, releasing the meshing limitation between the two limiting racks and the limiting gear. Rotating the rotating sleeve then causes a screw to rotate synchronously, thus achieving meshing with another gear to be tested. After the two gears mesh, releasing the pressure on the rotating sleeve allows the rectangular plate to reset under the elastic action of a compression component. The rectangular plate's pressure on the rotating sleeve resets it, and the reset unit, in conjunction with this, causes the two limiting racks to move towards each other, achieving meshing with the limiting gear and preventing arbitrary rotation.

[0004] To address the issue of poor stability in existing inspection devices that rely solely on springs for positioning, current technology employs multiple return springs to drive two limiting racks to move in opposite directions, thereby achieving meshing with the limiting gears. However, this approach still presents the problem of inconvenience in adjusting the position between the gear under test and the detection gear during use, thus reducing the flexibility of the inspection device.
