Manufacturing method of valve worm gear box

Technical field:

The utility model relates to a worm gear box, in particular to a valve worm gear box.

Background technique:

At present, the valve worm gear box is widely used in industrial production and engineering construction, and plays a very important role.How to improve the performance of the worm wheel and worm in the worm gear box is one of the key links.In the existing worm gear box structure, when the worm in the box rotates, it is easy to cause friction with the inner wall of the box, which will make the rotation of the worm wheel and the worm insufficiently slippery and directly cause poor application performance.Therefore, providing a valve worm gear box with excellent performance and convenient application has become one of the problems to be solved urgently by those skilled in the art.

Utility model content:

The purpose of the utility model is to overcome the above shortcomings and provide a valve worm gear box with simple structure, excellent performance and significant practical effect.In order to achieve the above-mentioned object, the technical solution adopted by the present utility model is a valve worm gear box, which includes a box body, the box body is axially provided with a worm wheel shaft hole, and the upper right side is correspondingly provided with a worm positioning hole; The outer side of the worm positioning hole in the box body is provided with an annular groove.The beneficial effects of the utility model are that the structure is simple, the design is reasonable, the rotation matching performance of the worm wheel and the worm is effectively ensured, the practical effect is very significant, the processing is simple and convenient, the application is wide, and it is suitable for large-scale industrial production.

Figure 1 is a schematic diagram of the structure of the utility model; in the figure, 1 box body, 2 worm wheel shaft holes, 3 worm positioning holes, and 4 annular grooves.

Detailed ways:

In the following, with reference to the drawings and preferred embodiments, the specific implementation manners provided according to the present utility model

For details, refer to Figure 1 below. A valve worm gear box includes a box body 1, a worm wheel shaft hole 1 is axially provided in the box body 2, and a worm positioning hole 3 is correspondingly provided on the right side of the upper part; The outer side of the worm positioning hole 1 in the box 3 is provided with an annular groove 4.Usually, the worm is placed inside and outside the box 1 into two parts. Now, the worm part placed in the box 1 is provided with an annular groove 1 on the inner wall of the box 4, which effectively avoids the friction between the worm part and the inner wall of the box 1 Scratching can make the worm part placed in the box 1 and the worm wheel rotate more flexibly and freely.The detailed description of the valve worm gear box with reference to the above embodiments is illustrative rather than restrictive; therefore, changes and modifications without departing from the general concept of the present utility model should fall within the protection scope of the present utility model.

Rights request:

A valve worm gear box includes a box body, the box body is axially provided with a worm wheel shaft hole, and the upper right side is correspondingly provided with a worm positioning hole; the feature is that the outer side of the worm positioning hole in the box body is provided with an annular groove.

Patent abstract:

The utility model relates to a valve worm gear box, which comprises a box body. The box body is provided with a worm wheel shaft hole in the axial direction, and a worm positioning hole is correspondingly provided on the right side of the upper part; There is an annular groove.In this way, the worm part placed in the box body can rotate more flexibly with the worm wheel.The utility model has a simple structure and a reasonable design, which effectively guarantees that the worm wheel and the worm have excellent rotation matching performance, and the processing is simple and convenient, and the practical effect is very significant.
