Description

Technical Field

[0001] This utility model belongs to the field of gearbox technology, and in particular relates to a gearbox noise testing device. Background Technology

[0002] The gearbox is a functional component of CNC machine tools, specifically the turret transmission mechanism. The gearbox is mounted on one end of the drive shaft, while the other end houses the drive motor and coupling. Inside the gearbox is a pair of transmission bevel gears. Gearbox transmission noise is a crucial indicator of turret manufacturing quality and must be strictly controlled during manufacturing. Previously, due to the lack of noise testing equipment, noise testing had to be conducted after the turret was assembled. If the gearbox noise exceeded the standard, rework was extensive and time-consuming, severely impacting production schedules and increasing costs. Therefore, a gearbox noise testing device is proposed.

[0003] For example, Chinese patent CN204903161U discloses a torque and noise testing device for a high-speed train gearbox, including a mounting base on which a torque testing device and a noise testing device are respectively mounted. The torque testing device includes a torque display, a servo motor, a test drive shaft, and a torque sensor. The servo motor is connected to the test drive shaft through a gearbox, and the torque sensor is electrically connected to the torque display through a data cable. The noise testing device includes a noise sensor and a noise display.

[0004] The aforementioned patent has the following problems:

[0005] Compared to existing technologies that simulate noise testing of gearboxes, these methods cannot simulate the gearbox transmission mechanism or ensure the gearbox moves according to specified requirements. This increases workload and reduces efficiency. Furthermore, given the variety of turret types and specifications, and the varying sizes and lengths of gearboxes and drive shafts, existing technologies require highly versatile testing equipment capable of handling noise testing of various gearboxes and drive shafts. Therefore, we propose a gearbox noise testing device. Utility Model Content
