Abstract
A spring type pumping unit belt tensioner comprises a holder (1), a roller (2), a cross shaft (3), a central shaft (4), a guide bolt (6), a shell (7), a spring (8) and a base (9). The shell (7) of the spring type pumping unit belt tensioner is of an inverted Y-shaped cylindrical structure, the lower end of the shell (7) and the rectangular base (9) are welded together, the upper part of the shell (7) is a hollow cylinder, the bottom of the shell (7) is provided with an annular groove, the upper part of the shell (7) is provided with the guide bolt (6), the central shaft (4) is provided with a guide groove (5), the spring (8) is sleeved on the central shaft (4), the central shaft (4) is mounted in the shell (7), the upper end of the central shaft (4) is connected with the U-shaped holder (1), and the roller (2) is provided with bearings cooperating with the cross shaft (3), and is mounted in the middle of the holder (1). The structure of the spring type pumping unit belt tensioner is simple, the spring type pumping unit belt tensioner is convenient to mount, the service life is long, the spring type pumping unit belt tensioner can ensure that a pumping unit belt can be always tensioned under the action of the spring force, the transmission efficiency of the pumping unit belt is high, electricity is saved, the production rate of an oil well is increased, and the output of crude oil is increased.
Description
Technical field
the utility model relates to oil field machinery oil field belt of oil pumping machine swelling device, particularly is a kind of spring belt of oil pumping machine expanding tense machine.
Background technique
are present, and in the oil field machinery oil production process, the degree of tightness of belt of oil pumping machine directly affects the transmission efficiency of pumping unit; General fixed strain or the application hydraulic pressure belt of oil pumping machine distend wheel of adopting, the belt of oil pumping machine fixed strain is along with the pumping unit prolongation of running time, the variation of load; Stretch gradually and wear out; Transmission efficiency descends gradually, and artificial adjustment labor intensity is big, and the influence oil recovery is produced; And hydraulic pumping unit belt distend wheel complex structure, fragile, the life-span is short, cost is high, thereby existing technology can not address the above problem preferably.
Summary of the invention
The purpose of
the utility model is exactly the above-mentioned defective that exists to existing technology, and a kind of spring belt of oil pumping machine expanding tense machine is provided.
The technological scheme of
the utility model comprises: support, roller, transverse axis, central shaft, guide blot, housing, spring, base.The housing of its spring belt of oil pumping machine expanding tense machine is for falling " Y " shape cylindrical-shaped structure, and lower end and rectangular base are welded as a whole, and top is divided into the hollow cylinder body; The bottom is provided with circular groove; Top is provided with guide blot, and central shaft is provided with guiding groove and is with spring, in the housing of packing into; The central shaft upper end connects with " U " shape support, and roller is equipped with bearing and cooperates the centre that is installed in support with transverse axis.
The beneficial effect of
the utility model is: simple in structure, easy for installation, and long service life; Under the effect of spring force, make belt of oil pumping machine be in the swelling state all the time, the belt of oil pumping machine transmission efficiency is high; Saving power, rate when improving oil well production increases crude output.
Description of drawings
accompanying drawing is the utility model axle side structure schematic representation.
In
accompanying drawing, 1. support, 2. roller, 3. transverse axis, 4. central shaft, 5. guiding groove, 6. guide blot, 7. housing, 8. spring, 9. base, 10. fixed hole.
Embodiment
Below in conjunction with accompanying drawing further elaboration is done in the enforcement of the utility model:
By shown in the figure, spring belt of oil pumping machine expanding tense machine is made up of support 1, roller 2, transverse axis 3, central shaft 4, guide blot 6, housing 7, spring 8, base 9
.Its housing 7 is for falling " Y " shape cylindrical-shaped structure, and lower end and rectangular base 9 are welded as a whole, and top is divided into the hollow cylinder body; The bottom is provided with circular groove; Top is provided with guide blot 6, and central shaft 4 is provided with guiding groove 5 and is with spring 8, in the housing 7 of packing into; Central shaft 4 upper ends connect with " U " shape support 1, and roller 2 is equipped with bearing and cooperates the centre that is installed in support 1 with transverse axis 3.During use spring belt of oil pumping machine expanding tense machine is installed in belt below, passes fixed hole 10 to base 9 usefulness bolts and be connected and fixed with oil pumping unit base and in position get final product.
