Abstract
The utility model relates to a membrane type coal gas meter rotating mechanism which comprises a rocking arm, a right connecting rod, a left connecting rod, a crank gear, a third wheel, a pole-pulling gear, etc. The rocking arm is connected with a membrane group, and the rocking arm is respectively connected with the right connecting rod and the left connecting rod. The right connecting rod and the left connecting rod are connected with a valve cover, and the crank of the crank gear is connected with the kidney bore of the valve cover. The crank gear is meshed with the third wheel, and the third wheel is meshed with the pole-pulling gear to transfer the power. The frame of the third wheel adopts symmetrical structure, and both sides of the center are respectively provided with a third wheel support and an anti-inversion structure. Both sides of the center are respectively provided with the third wheel support and the anti-inversion structure, and a front meter and a back meter can be used universally. The mechanism overcomes the disadvantage that a dead point is easy to appear in the alternating movement of the existing mechanism. The length of the rocking arm and the connecting rod can be adjusted to increase the force moment, so that the running of the mechanism is more flexible and stabler. Simultaneously, the dimension of the mechanism in the width direction is reduced, and the external form of the whole mechanism is small and exquisite.
Description
Technical field
The utility model belongs to the measuring instrument technical field, is specifically related to a kind of deaphragm gas meter slew gear.
Background technology
Present deaphragm gas meter slew gear form mainly contains three kinds, promptly alternately reciprocating type, swing type, rotary, wherein preceding two kinds of mechanism kinematic moments require bigger, and it is dumb to move, be prone to the dead point, at present rotary in the majority, wherein be divided into gear-driven form again, the low and difficult manufacturing because of the worm and gear transmission efficiency again, use seldom, and the structural design of gear-driven form is unreasonable, and mechanism's operation is dumb, and size is bigger.
Summary of the invention
The utility model is at the prior art above shortcomings, purpose is to provide a kind of deaphragm gas meter slew gear, overcome the shortcoming that the to-and-fro movement of existing mechanism is prone to the dead point, and by adjusting the length of rocking arm and connecting rod, strengthen moment, make mechanism's operation more flexibly, steadily, the size of reducing mechanism Width makes the entire mechanism external form small and exquisite simultaneously.
The technical solution of the utility model is as follows:
The deaphragm gas meter slew gear comprises rocking arm, left and right sides connecting rod, crank gear and third wheel and dead man gear etc., have the diaphragm group to connect rocking arm; rocking arm connects left and right sides connecting rod respectively; left and right sides connecting rod then is connected with valve gap; the crank of crank gear links to each other with the slot of valve gap; crank gear and third wheel mesh, third wheel again with dead man gearing mesh transferring power.Third wheel was stuck on the wheel carrier.When gas is entered in the table by draft tube, change by the core body gas circuit, gas promotes the diaphragm group and drives the rotation alternately continuously of left and right sides rocking arm, passing through rocking arm again---connecting rod transmits moment of torsion drive valve gap and moves in a circle, crank gear and third wheel engagement then, motion is delivered to dead man gear and crank gear, and the dead man gear passes to dead man to motion again, and dead man is connected to reach the purpose of metering with the counter of outside again.
The described wheel carrier of crossing adopts symmetrical structure, and the both sides, center are left third wheel supporting and anti-reverse-rotation structure respectively, and the both sides, center are left third wheel supporting and anti-reverse-rotation structure respectively, and positive and negative table can generally be crossed wheel carrier, only needs third wheel and dead man gear are installed on opposite side.Wherein third wheel meshes simultaneously with crank gear and dead man gear respectively, crank gear and each self-corresponding dead man gearing mesh.
The rocking arm of this mechanism is long, and connecting rod is short, to increase mechanism's moment, reduces volume.
The advantage of this mechanism:
1, adopt the symmetrical structure design owing to cross wheel carrier, positive and negative table can be general.
2, use valve gap, connecting rod, rocking arm set to constitute circular motion, avoid original shortcoming that is prone to the dead point in the swivel motion.
3 and rocking arm is long and connecting rod is shorter, the benefit of doing like this is to reduce the Width size when entire mechanism moment is strengthened, and moment adds the motion of ambassador's entire mechanism more steadily and flexibly, reduces size and makes the profile of whole table smaller and more exquisite.
Description of drawings
Fig. 1 is mounting structure figure of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 was wheel carrier and third wheel and anti-reverse mechanism installation enlarged drawing;
Fig. 4 is the valve gap vertical view.
Embodiment
Below be that example specifies the utility model with aluminum hull deaphragm gas meter slew gear.Referring to Fig. 1 and Fig. 2, this deaphragm gas meter slew gear is made up of Rocker arm 4, left and right sides connecting rod 2, crank gear 9 and third wheel 1 and dead man gear 6 etc.Connect Rocker arm 4 by diaphragm group 8, Rocker arm 4 connects left and right sides connecting rod 2 respectively, and wherein the rocking arm design is long, and link design is shorter.Left and right sides connecting rod 2 is connected with valve gap 7, and crank gear 9 links to each other with slot 12 on the valve gap 7 by crank, referring to Fig. 4, and crank gear 9 and third wheel 1 engagement.Referring to Fig. 3, third wheel 1 was stuck in the wheel carrier 5 one side third wheels supporting 10, and third wheel supporting 10 is symmetricly set on both sides with the center of mistake wheel carrier 5, and anti-reverse-rotation structure 11 was stuck on the wheel carrier 5.Be stuck in dead man gear 6 engagements of third wheel 1 and this side on the wheel carrier 5, gave dead man transmission of power.
