In order to prevent the gear shaft of the helical helical gear reducer from falling off, the anti-loosing device of the output helical gear of the helical helical gear reducer has been improved. The improved device is to process a section of thread at the lower part of the output gear spline and assemble In addition, the round nut 3 and the check washer 2 are added, and the axial clearance of the two single-row tapered roller bearings is adjusted by the round nut. After the above improvements, compared with the structure of the slewing gear reducer, it has the following advantages:
1. The anti-loosening device is reliable and not easy to appear loose.
2. The structure is simple, and the thread at the lower part of the output gear spline is completed at one time when processing the output gear. The coaxiality of the two parts is guaranteed. The use of standard round nuts can ensure that the output gear shaft rotates with the bearing and the wheel frame, so it is easy to manufacture and install. Improvement of the anti-falling device of the output gear shaft of the slewing gear reducer.
3. The axial distance between the two bearings has been increased. Because the rotary support of the slewing helical gear reducer is mainly supported by the two bearings on it, the increase in the distance between the two bearings can increase the rotational stability and bearing capacity of the slewing helical gear reducer. The round nut is used to adjust the axial clearance between the two bearings, which is easy and reliable to adjust. It can ensure the normal operation of the slewing gear reducer.
4. Long service life. The improved anti-loosening device has been used for more than two years, and so far no failure of the helical gear reducer due to the output gear shaft falling off has been found.
