Description

Technical Field

[0001] The utility model relates to the field of worm gear reducers, in particular to a low-noise worm gear reducer. Background Art

[0002] The worm gear reducer is a commonly used reduction device, which is mainly composed of a driving wheel (worm) and a driven wheel (worm wheel). When the driving wheel rotates, the driven wheel will also start to rotate due to the meshing of the helix on the driving wheel and the gear on the driven wheel. In this process, the driving wheel will apply a torque, which is transmitted to the driven wheel through the helix, so that the driven wheel rotates under the action of the torque. Since the number of teeth of the worm wheel is relatively large, the worm gear reducer can achieve a larger reduction ratio, and the low-noise worm gear reducer accurately calculates and optimizes the gear module, number of teeth, tooth shape and pressure angle parameters to reduce the impact and noise when the gears are meshed. The low-noise worm gear reducer adopts advanced bearing and sealing design to reduce friction and vibration during operation. By improving the structure of the box, the rigidity and stability are increased, and the noise caused by vibration is reduced.

[0003] The existing worm gear reducer includes a mounting shell, a worm wheel and a worm, and the top side of the worm is meshed with the bottom side of the worm wheel. Two upper mounting holes are respectively provided on the opposite sides of the mounting shell, and two lower mounting holes are respectively provided on the other opposite sides of the mounting shell. The left and right ends of the worm and the front and rear sides of the worm wheel are respectively arranged in four ball bearings fixedly arranged on the inner side walls of the two lower mounting holes and the two upper mounting holes. The left end of the worm and the central area of ​​the front side wall of the worm wheel are respectively provided with an input shaft and an output shaft, and the input shaft and the output shaft extend out of the mounting shell through the lower mounting hole and the upper mounting hole respectively. When the worm gear reducer is used, the input shaft is installed at the output end of the motor, and the output shaft is connected to the mechanism that requires power. Turn on the motor, so that the motor drives the input shaft to rotate, and the rotation of the worm drives the worm wheel to rotate, reducing the number of revolutions of the motor to the required number of revolutions, and making the power mechanism work through the output shaft. If the existing worm gear reducer is poorly lubricated during operation, it will produce a lot of noise. In some mechanical fields with high requirements for noise reduction, it will not meet the requirements during use. The worm gear reducer requires proper lubrication during operation to ensure its normal operation and extend its service life. However, the existing lubrication method usually requires manual disassembly of the mounting shell and manual application of lubricating oil. This method may have some inconveniences, such as cumbersome operation, time-consuming and labor-intensive, which reduces operating efficiency and increases labor costs to a certain extent.

[0004] Therefore, it is necessary to provide a new low-noise worm gear reducer to solve the above technical problems. Utility Model Content
