Abstract
The utility model discloses a combining belt of a pumping unit, comprising a C type triangular belt. The bottom of the C type triangular belt is provided with a continuous thickened layer which is connected with each single belt to form integration. The utility model with combining integral structure solves the problem of uneven stress caused by the incongruity of the size of the belts fundamentally, extends the service life of the belt, makes the load distribution homogeneous, and avoids the torsion phenomenon of the belt in a sheave groove. The utility model is widely used in a beam pumping unit or similar occations.
Description
One. technical field: the utility model relates to petroleum industry used for oil extractor drivign belt, particularly a kind of pumping unit grouped belt.
Two. background technique: the C shape vee belt that the existing pumping unit transmission in oil field is used, all be one one and be installed in individually on the belt of oil pumping machine wheel, be generally five.But the belt of Shi Yonging exists following shortcoming or deficiency like this: there is the phenomenon that causes different in size in (1) five belt, cause and respectively be with unbalance stress, short, fatigue fracture easily takes place because of bearing bigger load, long then skids because of bearing less load, easily cause the heating wearing and tearing, this has just shortened the working life of belt greatly; (2) because the different in size of belt causes, interband load inequality can not make every band all reasonably work under the pre-stressed state, between or the phenomenon that also twists, thereby make the stability of transmission variation, and reduced the transmission efficiency of belt, increased the power consumption of motor.
Three. summary of the invention: the purpose of this utility model provides a kind of improved pumping unit grouped belt, it can be avoided effectively and overcome shortcoming or the deficiency that exists in the prior art, the length unanimity of belt, stressed even, rate of tension is suitable, makes belt be in work under the rational pre-stressed state, thereby prolongs the working life of belt, improve transmission efficiency, reduce consuming.
Pumping unit grouped belt described in the utility model comprises C type vee belt, and a continuous thickening layer is installed in bottom, described C type vee belt, and this thickening layer and each single belt combine as a whole.
Wherein, the described belt number that combines as a whole is the 3-7 root.
The utility model compared with prior art has following advantage:
1, owing to adopt the joint group integrative-structure, fundamentally solved belt, prolonged the working life of belt because of the unbalance stress problem that causes that causes different in size;
2, owing to adopt the joint group integrative-structure, load distribution is even, has avoided the torsion phenomenon of belt in race, has improved stability of transmission;
3, owing to adopt the joint group integrative-structure, make the belt pulley outer surface also become working surface, under identical tension force, the friction between belt and the belt pulley increases, and has improved effective tension, therefore, has improved transmission efficiency.
Four. description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is that structure A-A shown in Figure 1 is to cross-sectional schematic.
Five. embodiment:
Referring to Fig. 1-Fig. 2, a kind of pumping unit grouped belt comprises C type vee belt 1, and a continuous thickening layer 2 is installed in the bottom of described C type vee belt 1, and this thickening layer 2 combines as a whole with each single belt.The belt number that combines as a whole is the 3-7 root, can prepare concrete radical according to actual needs.
Claims (2)
1, a kind of pumping unit grouped belt comprises C type vee belt, it is characterized in that installing a continuous thickening layer bottom the described C type vee belt, and this thickening layer and each single belt combine as a whole.
2, pumping unit grouped belt according to claim 1 is characterized in that the described belt number that combines as a whole is the 3-7 root.
