Abstract
一种新型的无切换式机械换向装置。它是属于 对机械换向装置的改进。该装置是通过改进和优化 曲柄连杆机构的尺寸及齿轮机构，而将连续转动的动 力转换成能实现近两转的正、反往复摆动。它主要是 由曲柄、连杆、摇杆及机架等构成。
A new type of switchless mechanical reversing device. It belongs to the improvement of the mechanical reversing device. The device converts the power of continuous rotation into forward and reverse reciprocating swings capable of nearly two revolutions by improving and optimizing the size of the crank connecting rod mechanism and the gear mechanism. It is mainly composed of crank, connecting rod, rocker and frame.
Description
The utility model relates to a kind of novel no switching type mechanical commutation device.It is the improvement that belongs to mechanical commutation device.This device is size and the gear mechanism by improvement and optimization connecting rod, and the power-converting that will rotate continuously becomes can realize the nearly two positive and negative reciprocally swingings that change.It mainly is to be made of crank, connecting rod, rocking bar and frame etc.
In the Oilfield Development Engineering of petroleum industry, drum type pumping unit is the extracting device of oil a kind of commonly used of numerous oil recovery machiner devices.Though such extracting device of oil is widely used in the production scene, the commutation in its device partly needs powershift, thereby brings a series of problems such as volume is big, noise height.At present, domestic drum type pumping unit mostly is the mechanical switching device, and especially concerning the pumping unit of heavy machinery, the caused problem of powershift is too many, and once proof several mechanical commutation device all do not lead to the failure because of key issue passes a test.
The purpose of this utility model provides a kind of novel no switching type mechanical commutation device with regard to being to avoid above-mentioned the deficiencies in the prior art part, it is proportional sizes and gear mechanism by the improvement connecting rod, and makes the power-converting of continuous rotation become positive and negative reciprocally swinging.This device mainly is to constitute crank-connecting rod by crank, connecting rod, rocking bar, driven gear, working gear and frame (casing), its major technology characteristics are that the end with crank links to each other with line shaft, the other end links to each other with an end of connecting rod, the other end of connecting rod then links to each other with an end of rocking bar, and the other end of its rocking bar links to each other with the axle of driven gear; And its crank: connecting rod: rocking bar: the ratio of frame is 1:2.5～3.05:1.3～1.4:2.65～3.15, and the velocity ratio of its driven gear and working gear is 1/5～1/6.
Accompanying drawing is structural representation of the present utility model
The drawing of accompanying drawing is described as follows:
1 ┄ crank, 2 ┄ connecting rods, 3 ┄ rocking bars, 4 ┄ frames (casing)
5 ┄ driven gears, 6 ┄ working gears
In order to realize better above-mentioned purpose of the present utility model, designer of the present utility model designs rocking bar (3) on certain Radius of driven gear (5), the axle center that is driven gear (5) is an end of rocking bar (3), and another point on certain Radius of driven gear (5) then is the other end of rocking bar (3).
Come enumeration structural feature of the present utility model below in conjunction with drawings and Examples:
In actual design with in making, artificer of the present utility model is that the ratio with each size of this connecting rod is designed to crank: connecting rod: rocking bar: frame=1:2.5～3.05:1.3～1.4:2.65～3.15, the velocity ratio of its driven gear and working gear are 1/5～1/6; In order to make this model utility more be adapted to practical application, the artificer also is designed to rocking bar (3) be the structure of one with driven gear (5), the axle center that is driven gear (5) is an end of rocking bar (3), and another point on driven gear (5) radius (determining according to calculating) is the other end of rocking bar (3); Driving shaft (or driving wheel), driven gear (5) and the working gear (6) that will drive crank (1) by frame (4) are fixed in the casing by its design proportion.Like this, power by the continuous motion of crank (1) input, make rocking bar (3) convert reciprocal swing to by connecting rod (2), pass through cooperating of the driven gear (5) that is integrated with rocking bar (3) and working gear (6) again, the continuous motion of input can be transformed into positive and negative reciprocally swinging, its angle of oscillation can reach more than 540 °; Drive the upper and lower motion of sucker rod again by other device, can realize job requirement.In addition, both the utility model can be installed in the casing of enclosed, also can be installed in the non-casing of open type according to the real work needs.
Because drum type pumping unit is a kind of very promising long stroke pumping unit, behind use the utility model, its power disposition is little with the beam pumping unit of the similar model of energy consuming ratio as calculated, so it belongs to energy-saving type.In addition, volume of the present utility model is little, pivot angle is big, simple in structure, reliable operation, has promotion and application prospect very widely.
