Specific embodiment
Below with reference to specific drawings and examples, the utility model is described in further detail.
As shown in Figure 1, embodiment discloses a kind of two-way gear assemblies of air blast oxygenation bi-directional regulator, mainly by
Positive gear 1, reverse gear 2 and jack-post 3 form.
As shown in Figure 1, the forward direction gear 1 is used to be fixedly mounted on the shaft 4.1 of potentiometer 4, positive gear 1 includes
The outer peripheral surface of positive gear hub 1a, the forward direction gear hub 1a by upper end is equipped with positive gear teeth 1b, on outer peripheral surface on lower side
It is not provided with the gear teeth；The reverse gear 2 is rotatably installed on jack-post 3, and reverse gear 2 includes reverse gear hub 2a, described reversed
Gear hub 2a is not provided with the gear teeth on the outer peripheral surface of upper end, and outer peripheral surface on lower side is equipped with reversed gear teeth 2b, the reversing wheel
The top tooth 2b is meshed with the forward direction lower part gear teeth 1b.
As shown in Figure 1, the forward direction gear teeth 1b is identical as the length of reversed gear teeth 2b, positive gear teeth 1b in the present embodiment
Length with reversed gear teeth 2b site of engagement is the half of forward direction gear teeth 1b or reversed gear teeth 2b overall length.So set
It sets, it is ensured that the engaged transmission between positive gear teeth 1b and reversed gear teeth 2b is steady reliable.
As shown in Figure 1 and Figure 2, in the present embodiment, the jack-post 3 is equipped with the positioning abutted against with 2 lower end surface of reverse gear
Step 3a.So set, can implement reliably to install positioning to reverse gear 2, avoid reverse gear 2 axial on jack-post 3
Play guarantees positive gear 1 and 2 stable drive of reverse gear.
3 lower end of jack-post is equipped with linkage section 3b, and the outer diameter of the linkage section 3b is less than the outer diameter of the positioning step 3a,
The periphery the linkage section 3b is equipped with full thread.So set, when installing jack-post 3 on the box body to bi-directional regulator, positioning
The lower end surface of step 3a can be abutted against with box wall, guarantee that the installation of jack-post 3 is firm.
In the present embodiment, in order to guarantee that reverse gear 2 smooth can rotate, it is equipped between the reverse gear 2 and jack-post 3
Bearing, the bearing preferably use oilless bearing.
In the present embodiment, internal spline is equipped in the inner hole of the forward direction gear 1.So set, by turning in potentiometer 4
It is correspondingly arranged external splines on axis 4.1, the transmission connection between positive gear 1 and the shaft 4.1 of potentiometer 4 can be made more reliable
It is convenient.
When concrete application, as shown in Figure 5, Figure 6, the footstalk of combustion gas assembly drives double-layer gear in rotation whole process counterclockwise
5 synchronize rotation counterclockwise, and the incomplete gear teeth 5a of the lower layer of double-layer gear 5 is first engaged with reversed gear teeth 2b, drive reverse gear 2 suitable
Hour hands rotation, reverse gear 2 rotates clockwise drives the positive rotation counterclockwise of gear 1 again, to make the shaft 4.1 of potentiometer 4
Rotation, the resistance value of potentiometer 4 become smaller counterclockwise；After footstalk drives double-layer gear 5 to be rotated by 90 °, the incomplete gear teeth of lower layer
5a and reversed gear teeth 2b is disengaged, and the incomplete gear teeth 5b in upper layer enters with positive gear teeth 1b again at this time engages, and drives positive gear 1 suitable
Hour hands rotation, so that the shaft 4.1 of potentiometer 4 be made to rotate clockwise, the resistance value of potentiometer 4 becomes larger.
Since potentiometer 4 controls the air blower being oxygenated to gas-cooker air blast, when 4 resistance of potentiometer becomes smaller, air blower
Revolving speed becomes larger, and air blast oxygenation capacity also becomes larger；When 4 resistance of potentiometer becomes larger, the revolving speed of air blower becomes smaller, and air blast oxygenation capacity also becomes
It is small；In above-mentioned action process, in rotation whole process, on the one hand control first increases for gas quantity subtracts the footstalk of combustion gas assembly again
Small, on the other hand control air blast oxygenation also first increases reduces again, so that air blast oxygenation capacity and combustion gas assembly be made to realize for gas quantity
Bi-directional synchronization, air blast oxygenation function can be increased by making household gas range also, can be generated better calorific value, be reached energy-efficient effect
Fruit.
