New description: [New technical field] This creation is related to a worm clearance elimination mechanism, which is a gap compensation mechanism between a conical worm and a worm wheel. When the conical worm meshes with the worm wheel, the shaft is engaged. The direction can be adjusted to eliminate the gap to achieve the best fit. [Prior Art] The cooperation between the mast and the worm wheel is often used in machinery. The rotation of the worm is used to conduct the power through the meshing worm wheel to achieve the vertical direction of the shaft drive power output. Systems such as feed systems, deceleration systems or shaft drives. The general worm worm gear set has the structure as shown in the first figure and the second figure, respectively, which is a perspective view and a side view of the worm worm wheel set, which is composed of a worm 10 and a worm wheel 11 In combination, the radial self-rotation force of the 10th end of the worm can be generated to drive the worm wheel 11 to generate the axial output. This mechanism is generally used for the power transmission of mechanical mechanisms. However, after research and discussion by the creators, the following defects are still found: 1 ·Because the worm and the worm wheel are not adjusted after the initial setting of the meshing, during the working period, the squeaking tooth is prone to wear and a gap is generated, which may affect the power output to be unstable or the chipping phenomenon may occur, which may affect the production. Performance and speed. M397453 ^9.9>2 4 Amendment · Year of the Moon --·6 2· As in the above situation, the amount of wire of the parts is extremely impressive, and the amount of the product is also a long-term burden on the producer. [New content] Therefore, this creation and aiming to provide a worm contact 4 = to achieve the main purpose of the maintenance and efficiency of the power output by the combination of the tapered design and the female, the gap adjustable mechanism, and thus the maintenance and efficiency of the power output. Moreover, the worm-eliminating mechanism of the present invention can be adjusted by the cone-shaped worm, which greatly enhances the life of the component, and is another purpose of the creation. Furthermore, the tip seems to provide -_ Off _ except the mechanism, its 1 = ^ worm, can be set at the same time at the other end of the worm gear, the durability and efficiency of the k-lift parts, for the purpose of this creation. As for the detailed construction of the book, the application principle, function and effect, the complete understanding can be achieved by referring to the following description according to the drawings. [Embodiment] and the second figure are the stand diagram and side of the worm group of the visor: the structure of the j: the missing of the structure is as before, and will not be repeated here. And the first call, the side view of the _ _ _ _ _, can be called white to see, the creation of the === _ structure, _ system includes - cone worm 2 〇 and a 〇,, tapered amp At the front of 20, she is small, and the rear axle diameter is 3 M397453. The 3H-bar is larger and has a tapered shape, which makes it possible to change the knot on the worm and select a pulley 22 to drive. The conical worm 20 can smoothly drive the worm gear 21. 0 Please refer to the fifth and fifth diagrams respectively, which are schematic diagrams of the operation of the creation. It can be clearly seen from the figures that the mechanism is engaged when the mechanism is first engaged. When the contact point falls on point a, after a period of time, when the machine wears a large gap, the axial direction adjustment can be performed, and the tapered worm 2 is pushed to the axis direction to the new meshing contact point b, and discarded. The point of abutting contact point a, which has been worn out, is replaced by a new thread, so that the degree of fit can be optimized, the stability and efficiency of the power output can be improved, and the life of the machine can be extended. As shown in the sixth and seventh figures, another embodiment of the present invention is shown. In the worm clearance eliminating mechanism of the present invention, another set of tapered worms 30 may be added to the corresponding end according to requirements. Through the double worm 2 〇, 3 〇 meshing and adjustable characteristics, it can achieve unprecedented stability of the machine, and the chance of wear and clearance is greatly reduced. It can be seen from the above that the arbor clearance mechanism of the present invention does have the improvement of the worm and worm gear set, the lack of wear and short life, and the public use of the patent law is not disclosed. It is really good. - It must be stated that the above is the preferred embodiment of this creation. If the changes made according to the concept of this creation, the effect of its creation is still not 4 ^ 397453 "ϊδΐϊΠ }£i 9.- 2 years beyond the spirit of the instructions and illustrations, should be combined with Chen Ming in this creation 1 ^ ^ one.
