Abstract
The utility model relates to a constant power transmission mechanism which comprises an input shaft, an output shaft, a driving wheel connected with the input shaft and an driven wheel connected withthe output shaft. The driving wheel and the driven wheel are conjugate meshing variable parameter transmission wheels. The driven wheel can adopt an eccentric roller wheel. The driving wheel adopts avariable parameter cycloid gear which is conjugate and meshes with the driven wheel. After the transmission mechanism with the structure is adopted, a counter weight is left out for the whole machineand the weight, the power dissipation and the construction cost of the device are reduced.
Description
Technical field:
The utility model relates to a kind of driving mechanism, relate in particular to a kind of driving mechanism that can realize permanent power transmission.
Background technique:
In the reciprocal elevation and subsidence mechanical such as oil-field oil pumper, load changes in lifting process, as: load is big during lift, and backhaul is that load is little.Little when big when so just making moment of torsion on the transmission case output shaft.And traditional deciding determined that than transmission the rotating speed of output shaft is a constant, and therefore, the power of actual demand is a variable, so in the practical work process, motor can only be equipped with according to peak output.The problem that transmission power changes when solving load change adopts the method for reverse counterweight, and balancing weight moved downward when load was big, and a load hour balancing weight moves upward, and utilizes the moving equilibrium of balancing weight to fall the variation of partial load.This method can't realize permanent completely power transmission, and balancing weight also can increase weight and worker's consumption of equipment, increases construction cost.Existing in prior technology deficiency that Here it is.
The model utility content:
The technical problems to be solved in the utility model is exactly at the existing in prior technology deficiency, and a kind of permanent power driving mechanism that can realize permanent power transmission under the operating mode of varying load is provided.
This programme is realized by following technical measures: this perseverance power driving mechanism comprises input shaft, output shaft, driving wheel that links to each other with input shaft and the follower that links to each other with output shaft, and described driving wheel and follower are the variable element drive wheel of conjugation engagement.
Above-mentioned follower is eccentric roller wheel, and driving wheel is the variable element cycloidal gear that meshes with the follower conjugation.
Each roller distributes for waiting central angle on the above-mentioned follower.
Roller on the above-mentioned follower adopts rolling bearing, sliding bearing or bearing pin.
Above-mentioned roller is cylindrical or conical.
Above-mentioned driving wheel also can adopt eccentric roller wheel, and follower is the variable element cycloidal gear that meshes with the driving wheel conjugation.
The beneficial effect of this programme can learn that in this perseverance power driving mechanism, the follower that links to each other with output shaft adopts eccentric roller wheel according to the narration to such scheme, and the driving wheel that links to each other with input shaft adopts the variable element cycloidal gear with the engagement of follower conjugation.When load increased, the load torque on the output shaft increased, and the follower roller centre increases to the distance of output shaft axis, and this moment, velocity ratio reduced, thereby the power that guarantees output shaft remains unchanged; When load reduced, the load torque on the output shaft reduced, and the follower roller centre reduces to the distance of output shaft axis, and this moment, velocity ratio increased, thereby the power of output shaft is remained unchanged.Realized permanent power transmission by said structure in varying load situation underdrive mechanism.Adopt this driving mechanism can save balancing weight, alleviated the weight of equipment, reduced the worker's consumption and the construction cost of equipment.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the plan view of the utility model embodiment.
Among the figure, 1 is input shaft, and 2 is driving wheel, and 3 is output shaft, and 4 is follower, and 5 is roller.
Embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by embodiment.
A kind of permanent power driving mechanism, as shown in Figure 1, it comprises input shaft 1, output shaft 3, driving wheel 2 that links to each other with input shaft 1 and the follower 4 that links to each other with output shaft 3, described driving wheel 2 and follower 4 are the variable element drive wheel of conjugation engagement.Specifically, follower 4 can adopt eccentric roller wheel, driving wheel 2 adopts the variable element cycloidal gear with the engagement of follower 4 conjugation, and each roller distributes for waiting central angle on the follower 4, and the roller 5 on the follower 4 can adopt cylindrical or conical rolling bearing, sliding bearing or bearing pin.
The power P of output shaft 3=2 π n
o* T (t)=2 π n
i* i (t) * T (t), promptly
Wherein, n
oBe the rotating speed of output shaft 3, n
i(n
i=constant) be the rotating speed of input shaft 1, i (t) is a velocity ratio, and T (t) is the load torque on the output shaft 3.When load increased, the load torque on the output shaft 3 increased, and the center of the roller 5 on the follower 4 increases to the distance of output shaft 3 axis, and this moment, velocity ratio reduced, and the power that can draw output shaft 3 according to above-mentioned formula remains unchanged; When load reduced, the load torque on the output shaft 3 reduced, and the center of the roller 5 on the follower 4 reduces to the distance of output shaft 3 axis, and this moment, velocity ratio increased, and the power that can draw output shaft 3 according to above-mentioned formula remains unchanged.
Described driving wheel 2 also can equivalence replace with eccentric roller wheel, and follower 4 adopts the variable element cycloidal gear with the engagement of driving wheel conjugation.
Can pass through existing techniques in realizing without the technical characteristics of describing in the utility model, not repeat them here.
