Abstract
The utility model relates to a chute type lead screw transmission device of a transmission device. A limiting screw nut is respectively arranged at the upper part and the lower part of a lead screw in a box body, a symmetrical gudgeon is respectively arranged at both ends of a transmission screw nut on the lead screw, one end of a crank, which is in the shape of a shifting fork, is connected on the gudgeons, and the other end of the crank is connected with a valve shaft of a valve. The utility model belongs to a primary transmission device, can effectively prevent the crank from turning over or rotating, reduces the abrasion between lead screw nuts, and has the advantages of convenient regulation and high transmission efficiency.
Description
Technical field
The utility model relates to transmission device.
Background technique
Existing transmission device is feed screw nut's transmission device, nut on the interior screw mandrel of connecting rod and transmission case body on its device is connected, the crank that is connected on the connecting rod is connected with the valve shaft of valve, simultaneously the right and left in the transmission case outside respectively is provided with a stop screw, and the right and left on the top of crank respectively is provided with a boss as the spacing usefulness of switch.This device promotes connecting rod by transmission nut, is rotated by the connecting rod throw crank again, drives the two-stage drive that valve shaft rotates by crank then.This transmission structures complexity, transmission efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of chute-type lead screw transmission mechanism, and it is a kind of one-level drive mechanism, and the high transmission device of transmission efficiency.
The technical solution of the utility model is as follows:
The utility model is made up of casing, screw mandrel, transmission nut, crank, stop nut, transmission nut in the casing and stop nut are on screw mandrel, respectively there is a stop nut upper and lower of screw mandrel, respectively there is a symmetrical gudgeon on the both sides of transmission nut, one end of crank is a shift fork shape, be connected with the gudgeon on the transmission shaft, the other end is connected with the valve shaft of valve.
The center line of gudgeon and the disalignment of screw mandrel.
Crank shift fork shape one end center line and angle of crank center skew are θ °.
Advantage of the present utility model is as follows:
1, gudgeon of the present utility model bindiny mechanism can prevent the crank upset effectively, and can bear the radial force of power screw, has reduced the wearing and tearing between the feed screw nut, has improved transmission accuracy, has prolonged working life.
2, the utility model transmission nut and screw mandrel adopt split-type structural, and cost is low, easy to maintenance, screw mandrel double supporting structure good rigidly, and stop nut is easy to adjust, spacing reliable.
3, the utility model adopts crank one end to be connected with nut on the screw mandrel, the gear stage that the crank the other end is connected with valve shaft on the valve, and it is simple in structure, transmission efficiency is high.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model side view.
Embodiment
