Detailed Description
The utility model is further described with reference to the following figures and embodiments.
With reference to fig. 1-4, the utility model relates to a worm gear elastic gap eliminating structure, which comprises a large worm shaft seat 1, a worm connecting shaft 2, a bearing 3, a spring 4, a large spring cover 5, a worm seat 6, a worm 7 and a worm wheel 8;
the worm wheel 8 is rotatably supported on the support, and the worm 7 is matched with the worm wheel 8; the worm 7 and the bearing 3 are arranged in the worm seat 6, and two ends of the worm 7 are supported in the worm seat 6 through the bearing 3. The big spring cover 5 is fixed on the surface of the worm seat 6 by screws, the worm seat 6 is rotatably connected on the big worm shaft seat 1 by the worm connecting shaft 2, the big worm shaft seat 1 is fixed on the support, the spring is supported between the spring cover and the support, and the spring is in a pre-compression state, so that the worm seat 6 has a tendency of rotating towards the direction of the worm wheel. After the large spring cover 5 and the spring 4 are installed, the structure is installed. The structure uses the worm connecting shaft 2 on the big worm shaft seat 1 as a rotating fulcrum, when the work meshing of the worm wheel 8 and the helical gear of the worm 7 is not tight, the bearing 3 and the big spring cover 5 are led out from the worm seat 6, and the big spring cover 5 is contacted with the spring 4, so that the whole worm 7 rotates in a small angle towards the direction of the worm wheel 8, and the clearance between the worm 7 and the worm wheel 8 is eliminated. The support is further provided with a crank 9, a rotating shaft of the crank 9 is supported on the support through a bearing seat 10, and the rotating shaft is connected with the worm seat 7 through a synchronous belt 11. The crank handle 9 is rotated to drive the worm 7 to rotate, and the worm 7 rotates to drive the worm wheel 8 to rotate.
