Abstract

The utility model provides a valve control device which comprises a motor, a reducing gear, an output shaft and a clutch, wherein the reducing gear comprises a double-enveloping worm wheel and a double-enveloping worm; a double-enveloping worm shaft is connected with the motor; the double-enveloping worm and the double-enveloping worm wheel are meshed; the double-enveloping worm wheel is sheathed on the output shaft and is connected by a key; the clutch is connected with the output shaft by a key and is connected with the double-enveloping worm wheel by coupling. The valve control device has the beneficial effects of high load bearing capability, high transmission effect improved to 0.3-0.5 from 0.1, and compact and reasonable mechanism.

Description

A kind of valve control device
Technical field
The utility model belongs to valve technology field, especially relates to a kind of valve control device.
Background technique
In existing technology; Reducing gear in the valve control device, employing be common worm couple, be equivalent to wheel and rack in the plane therebetween; Worm screw is similar with the screw rod shape again, and worm-and-wheel gear is commonly used to transmit motion and the power between two alternating axiss.During common worm and gear engagement driving, the relative sliding velocity of meshing wheel between cog is big, so frictional loss is big, efficient is low.On the other hand; Relative sliding velocity ambassador tooth surface abrasion is serious, heating is serious; In order to dispel the heat and to reduce wearing and tearing; Antifriction quality that normal employing price is comparatively expensive and wear resistance be material and good lubricating fitting preferably, thereby cost is higher, has technical problems such as transmission efficiency is low, Surface of action serious wear.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of valve control device.
The technological scheme that the utility model adopts is:
A kind of valve control device; It is characterized in that: comprise motor, reducing gear, output shaft and clutch, described reducing gear comprises double enveloping wormwheel and double-contracting network worm screw; Its double-contracting network worm shaft is connected with motor, double-contracting network worm screw and double enveloping wormwheel engagement;
Described double enveloping wormwheel is enclosed within on the output shaft, connects through key;
Described clutch is connected with output shaft through key, is connected with double enveloping wormwheel through the tooth embedding.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, double-contracting network worm screw is that the number of teeth that toroid helicoids worm and double enveloping wormwheel mesh simultaneously increases; Precise Grinding forms the raising of tooth face hardness roughness grade after the process cure process of the flank of tooth of double-contracting network worm screw, can reach very high flute profile precision; Flank of tooth area of contact is big and instantaneous two-wire contact is arranged, and the Line of contact total length extends; Form dynamic pressure oil easily in the lubricated big engagement in angle of the flank of tooth; But double-contracting network worm shaft tow sides direction rotation.Advantages such as it is big to have bearing capacity, and the transmission effect is high, and mechanism is tight, and is reasonable.

Embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing and instance.
As shown in Figure 1, the utility model is a kind of valve control device, comprises motor 1, reducing gear, output shaft 4 and clutch 5; Described reducing gear comprises double enveloping wormwheel 2 and double-contracting network worm screw 3, and its double-contracting network worm shaft is connected with motor 1; Double enveloping wormwheel 2 is enclosed within on the output shaft 4, connects through key; Clutch 5 is connected with output shaft 4 through key, is connected with double enveloping wormwheel 2 through the tooth embedding.
Motor 1 drives double-contracting network worm screw 3 and rotates, and is as shown in Figure 2, and double-contracting network worm screw 3 and double enveloping wormwheel 2 engagements drive double enveloping wormwheel 2 and rotate, and double enveloping wormwheel 2 drives output shaft 4 through clutch 5 and rotates.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
