[0002] The worm gear transmission structure is widely used in the field of mechanical transmission. The characteristics of the worm gear transmission are large transmission ratio, large force on the worm shaft as the power output shaft, low speed and self-locking.

[0003] The existing worm gear will produce wear during use, and the wear will cause a large amount of debris to be deposited on the worm wheel, which will further increase the degree of wear between the two under the action of the debris. At the same time, the existing worm wheel tooth profile is trapezoidal, which makes the edges and corners of the tooth profile more sharp, further increasing the wear between the worm wheel and the worm. Therefore, a new worm gear structure with optimized worm wheel tooth profile is needed to solve the above problems. Utility Model Content

The wear will cause a large amount of debris to be deposited on the worm wheel, and the degree of wear of the two will be further increased under the action of the debris. At the same time, the existing worm gear tooth shape is trapezoidal, which makes the edges and corners of the tooth shape more sharp, further increasing the wear problem between the worm wheel and the worm.

[0008] Preferably, the limiting mechanism comprises a limiting seat installed in the fixing frame and located at the bottom of the worm, a rubber block is installed in the limiting seat, and two sets of fastening screws are symmetrically installed on both side surfaces of the fixing frame.

[0009] Preferably, a collecting groove is provided in the limit seat, the rubber block is clamped in the collecting groove, and an end plate is installed at the bottom of the rubber block, and threaded holes compatible with fastening screws are provided in the limit seat and the fixing frame.

The surfaces of the two groups of sliding rods are commonly connected to a connecting plate, and a cleaning brush is installed on the surface of the connecting plate. The surface of each group of sliding rods is sleeved with a spring.

[0011] Preferably, a movable groove adapted to the slide rod is provided in the connecting plate, one end of the spring is mounted on the surface of the connecting plate, and the other end is mounted on the surface of the mounting frame.

[0012] The beneficial effects of the utility model are:

[0013] 1) With the new worm gear structure that optimizes the worm gear tooth shape, when the worm gear body and the worm are running, the two will wear each other, and the debris generated by the wear will further aggravate the wear. When cleaning, it is only necessary to use a cleaning brush to clean the debris deposited on the surface of the worm gear body and temporarily store it in the limit seat. When cleaning, it is only necessary to remove the rubber block to discharge the debris. The operation is simple and can greatly extend the service life and performance of the worm gear body and the worm.
