[detailed description of the invention]
Below in conjunction with accompanying drawing, this utility model is described in further detail:
nullSuch as Fig. 1、Shown in 2，A kind of half reciprocating oil pumper of gear driven tooth bar，Including base 7，Base 7 is provided with frame 8，Frame 8 is provided with motor 21、Decelerator 22，The outfan of decelerator 22 is meshed with input gear 1，Input gear 1 and upper input gear 19、Connect gear 2 to be meshed，Connect gear 2 to be meshed with lower input gear 3，Upper input gear 19 is coaxially fixed with upper gear 20，Lower input gear 3 is coaxially fixed with lower half side gear 4，Upper gear 20 and lower half side gear 4 engage with tooth bar 5 time different，Polished rod 18 is run through tooth bar 5 inside and is connected as one with tooth bar 5 on tooth bar 5 top by rod clamp 17，Tooth bar 5 slides up and down on pinion stand 16，Ballast box 11 is connected with tooth bar 5 by steel wire rope 13 by fixed pulley 15，Ballast box 11 is connected with steel wire rope 13 by suspension ring 12 built with balancing weight 9，Groups of springs 14 is fixed in frame 8 just to balancing weight 9.Described upper input gear 19 is coaxially fixed with upper gear 20, and lower input gear 3 is coaxially fixed on fuselage with lower half side gear 4.
The band sector degree in the same size of described upper gear and described lower half side gear is 180 degree, engage with described tooth bar when phase 180 degree and difference, described upper input gear is consistent with described lower input gear size and the number of teeth, and input gear is consistent with the number of teeth with connection gear size.
Ballast box is suspended on frame rear portion, and upper middle position is provided with suspension ring, and suspension ring are connected with steel wire rope, is framework 10 outside ballast box, and framework 10 is contacted with frame by roller 6, and framework is built with balancing weight.
In this utility model application process, groups of springs 14, it is fixedly installed in described frame 8, described groups of springs 14 is just to described balancing weight 9, and described groups of springs 14 is in the process that described balancing weight 9 moves up and down, and can be compressed by described balancing weight 9.In oil pumper stroke thereon and down stroke, due to the effect of groups of springs 14, speed will not cataclysm, acceleration is without unexpected change, it is to avoid the generation impacted, improves the life-span of pumping unit system.
In this utility model, when described upper gear 20 with described lower half side gear 4 respectively in described input gear 1 and the both sides being connected gear 2, described input gear 1 engages with described upper input gear 19, connecting gear 2 to engage with lower input gear 3, described the upper gear 20 divides with described lower half side gear 4 constant speed rotating Vortex and toothed portion and alternately engages with described tooth bar 5.
