Abstract

The invention belongs to an electromechanical integrated system, relating to a worm wheel-worm gearing used in engineering. And the invention basically comprises: worm wheel, bearing, worm box, small bearing end cover, bolt, worm wheel box cover plate, pin, worm wheel shaft, bearing end cover, worm wheel and worm wheel box. And the advantages of the invention: adopting a method of resolving worm wheel and worm into two independent box bodies, solving the problem that the gearing accuracy is reduced by reason that two engaging tooth surfaces of worm wheel-worm gearing auxiliary in the worm wheel-worm gearing are worn to generate gap, and achieving the purpose of improving worm wheel-worm gearing accuracy by regulating the gap between the worm box component and worm wheel box component, and for this purpose, the invention provides a trimmer mechanism for regulating worm wheel-worm gearing gap. And the invention can be used in worm wheel-worm gearing in engineering and other aspects.

Description

technical field [0001] The invention belongs to an electromechanical integration system and relates to a worm gear transmission mechanism used in engineering technology. Background technique [0002] The worm gear transmission mechanism is widely used in mechanical engineering technology because of its large transmission ratio, stable movement, low noise and compact structure. However, in the worm gear transmission mechanism, the two meshing tooth surfaces wear after the worm gear pair works for a period of time, resulting in a gap, resulting in a reduction in transmission accuracy. The solution method of prior art is as shown in Figure 1 and Figure 2, and it is made up of casing 1, worm screw 2, bearing 3, end cap 4, screw 5, worm gear shaft 6, worm gear 7. Because the original technology installs the worm gear and worm in the same box, the gap between the meshing surfaces is completely guaranteed by the machining accuracy and cannot be adjusted manually. Therefore, the tw...
