Description
Technical field
The utility model relates to a kind of worm gearing, particularly a kind of worm gearing that has interchangeable supporting link.
Background technique
Worm gearing is mainly used in the opening and closing of valve.The endoporus of worm gear must be consistent with shaft head shape on the valve in the worm gearing, with bolt worm gearing is installed on the valve upper flange during use, and shaft head is a Spielpassung on worm gear endoporus and the valve.When needs unlatching or throttle down, rotate the valve plate that handwheel just can open and close valve.Common worm gearing, include the worm shaft that an end links to each other with handwheel, the other end links to each other with worm screw by the worm screw axle sleeve, worm screw is positioned at a side of the housing that is made of upper box and lower box, middle part in the housing that is made of upper box and lower box is provided with worm gear, worm gear is meshed with worm screw, wherein shaft head Spielpassung on the endoporus of worm gear and the valve needs only and rotates the valve plate that handwheel just can open and close valve.
But the worm gearing of this structure, be when last shaft head shape timing, can only be furnished with a worm gearing that can cooperate with it, on the different valve of several nose shapes, during rotating shaft, just need be furnished with several the worm gearings that cooperate with it.Therefore, the waste and the high deficiency of product cost of material be arranged, use and for inconvenient.
Summary of the invention
The technical problem that will solve of the present utility model is, overcomes to have inconvenient problem with use in the prior art, and a kind of worm gearing that has interchangeable supporting link flexible and convenient to use is provided.
The technological scheme that the utility model adopted is: a kind of worm gearing that has interchangeable supporting link, including an end links to each other with handwheel, the worm shaft that the other end links to each other with worm screw by the worm screw axle sleeve, worm screw is positioned at a side of the housing that is made of upper box and lower box, middle part in the housing that is made of upper box and lower box is provided with worm gear, worm gear is meshed with worm screw, the endoporus of worm gear be provided be used for valve on the removable supporting link of shaft head Spielpassung, the external shape of its supporting link is the oblate shape that the endoporus with worm gear is complementary.
The utility model is made simple, at the bottom of the cost.Only need a worm gearing, adopt the method for changing supporting link, just can be connected, reach a tractor serves several purposes with rotating shaft on four kinds of difform valves, easy to use.

Embodiment
Provide specific embodiment below in conjunction with accompanying drawing, further specify the utility model and how to realize.
As shown in Figure 1 and Figure 2, the worm gearing that has interchangeable supporting link, include the worm shaft 5 that an end links to each other with handwheel 4, the other end links to each other with worm screw 12 by worm screw axle sleeve 8, worm screw 12 is positioned at a side of the housing that is made of upper box 20 and lower box 22, middle part in the housing that is made of upper box 20 and lower box 22 is provided with worm gear 9, worm gear 9 is meshed with worm screw 12, the endoporus of worm gear 9 be provided be used for valve on the removable supporting link 29 of shaft head Spielpassung.
As Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the external shape of the supporting link 29 of worm gear 9 endoporus is flat round hole shapes that the endoporus with worm gear 9 is complementary.
As shown in Figure 3, the endoporus 30 of first kind of supporting link 29 of worm gear 9 is that an end is a circular hole, and an end is a circular hole band keyway shape, promptly has a keyway at endoporus.
