DETAILED DESCRIPTION
[0021] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and not used to limit the scope of the utility model.
[0022] As described in the background, in the oilfield blocks where the power grid fails to achieve coverage, the driving of the pumping unit often relies on the engine fueled by wellhead associated gas, which is particularly common in oil-producing developing countries. In many cases, when the power of a single engine cannot drive the pumping unit, a larger engine needs to be replaced, and the old engine will be idle and scrapped, resulting in waste of resources. Therefore, the embodiment provides a new parallel output gear box.
[0023] Referring to Figures 1 to 5 The embodiment provides a new parallel output gear box, which comprises a bottom plate 1, and a plurality of second mounting holes 13 for locking the position of the gear box are formed in the upper surface of the bottom plate 1. The second mounting holes 13 can facilitate the installation of the gear box at the use position by using fixing bolts, thereby improving the stability during use.
[0024] The upper surface of the bottom plate 1 is fixedly connected with a fixed frame 2, and a plurality of first mounting holes 12 for sealing the gear box are formed in the upper surface of the fixed frame 2. The first mounting holes 12 can facilitate the sealing treatment of the gear box by using fixing bolts, and the sealing performance can be improved by using sealing strips during sealing.
[0025] The inner wall of the fixed frame 2 is rotatably connected with a second rotating rod 4 and two first rotating rods 3. The outer surface of each first rotating rod 3 is fixedly connected with a first gear 5 and a first transmission wheel 6, the two first transmission wheels 6 are drivingly connected through a transmission belt, the outer surface of the first rotating rod 3 is fixedly connected with a second gear 7, and the two first gears 5 are engaged with the second gear 7.
[0026] The fixed frame 2 can be connected with the bottom plate 1 in a welded manner, and an engine can be arranged outside the bottom plate 1. The output shaft end of the engine is fixed with the first rotating rod 3. After the engine is started, the first rotating rod 3 can drive the first gear 5 and the first transmission wheel 6 connected thereto to rotate, and the second gear 7 engaged with the two first gears 5 can drive the other first gear 5 to rotate, so that the first rotating rod 3 fixed with the other first gear 5 drives the other first transmission wheel 6 to rotate, and further drives the external pumping unit and other loads to operate.
[0027] Referring to Figure 1 The first transmission wheel 6 located in the upper left is used to drive the external pumping unit and other loads to operate, and the first rotating rod 3 located in the lower left can be used to connect the engine to realize power input.
[0028] The interior of the fixed frame 2 is filled with a lubricant to ensure the lubrication performance of the gearbox. The lubricant can be lubricating oil, semi-fluid grease, or molybdenum disulfide ultrafine powder. For gears with good sealing, high speed, heavy load, and good sealing performance, gear oil can be used for lubrication; for gears with poor sealing and low speed, semi-fluid grease can be used for lubrication; and for oil-free or high-temperature applications, molybdenum disulfide ultrafine powder can be used for lubrication, thereby reducing noise and wear during gearbox operation.
[0029] The inner wall of the base plate 1 is inlaid with four first bearings 9, and the inner rings of the four first bearings 9 are respectively fixed to the outer surface of the first rotating rod 3 at the corresponding position. By setting the first bearings 9, the first rotating rod 3 can be made more stable when rotating and the resistance of the first rotating rod 3 when rotating can be reduced, thereby avoiding the first rotating rod 3 from jamming and swaying during use.
[0030] Two second bearings 10 are embedded in the inner wall of the base plate 1, and the inner rings of the two second bearings 10 are fixed to the outer surface of the second rotating rod 4. By setting the second bearings 10, the second rotating rod 4 can be made more stable when rotating and the resistance of the second rotating rod 4 when rotating can be reduced, thereby avoiding the second rotating rod 4 from jamming and swaying during use.
[0031] The upper surface of the fixed frame 2 is provided with several first mounting holes 12 for sealing the gearbox. By setting the first mounting holes 12, the gearbox can be easily sealed with fixing bolts, and the sealing performance can be improved by using a sealing strip during sealing.
[0032] A high-efficiency component for improving the output efficiency of the gearbox is provided above the base plate 1. The high-efficiency component includes a third rotating rod 801 rotatably connected to the fixed frame 2, and a first bevel gear 802 fixed to the first rotating rod 3 at the corresponding position. A second transmission wheel 803 and a second bevel gear 804 are fixedly connected to the outer surface of the third rotating rod 801. The high-efficiency component also includes a support frame 805 rotatably connected to the first rotating rod 3 at the corresponding position, and the support frame 805 is fixed to the fixed frame 2. A fourth rotating rod 806 is rotatably connected to the inner wall of the support frame 805. Two third bevel gears 807 are fixedly connected to the outer surface of the fourth rotating rod 806, and both the first bevel gear 802 and the second bevel gear 804 mesh with the third bevel gear 807.
[0033] Another engine can be installed on the outside of the base plate 1. The output shaft of the engine is fixed to the third rotating rod 801. After the engine is started, the third rotating rod 801 drives the second transmission wheel 803 and the second bevel gear 804 connected to it to rotate. The two third bevel gears 807 that mesh with the second bevel gear 804 drive the first bevel gear 802 to rotate, thereby driving the first rotating rod 3 to rotate, thus enabling the auxiliary external oil pump and other loads to operate.
[0034] Furthermore, the first bevel gear 802, the second bevel gear 804, the support frame 805, the fourth rotating rod 806, and the third bevel gear 807 are combined to form a crown gear differential, which allows for a speed difference between the input first transmission wheel 6 on the lower left and the second transmission wheel 803 on the right. The base plate 1 can be divided into two chambers, with the gear chamber on the left responsible for power output and the differential chamber on the right responsible for power input to the second transmission wheel 803 on the right. This allows the two externally mounted engines to still achieve common power output even when there is a speed difference between them.
[0035] See Figure 1 and Figure 5 It is known that the inner wall of the fixed frame 2 is inlaid with two auxiliary bearings that respectively assist the rotational stability of the first rotating rod 3 and the third rotating rod 801, and the inner rings of the two auxiliary bearings are fixed to the outer surfaces of the first rotating rod 3 and the third rotating rod 801, thereby further improving the rotational stability of the first rotating rod 3 and the third rotating rod 801.
[0036] The inner wall of the base plate 1 is inlaid with a third bearing 11, and the inner ring of the third bearing 11 is fixedly connected to the outer surface of the third rotating rod 801. By setting the third bearing 11, the third rotating rod 801 can be made more stable when rotating and the resistance of the third rotating rod 801 when rotating can be reduced, thereby avoiding jamming and swaying of the third rotating rod 801 during use.
[0037] This gearbox is primarily designed for the oil industry, specifically for scenarios where engines directly and mechanically drive beam pumping units or belt-driven pumping units. It allows for the parallel operation of two engines mechanically, even if their outputs differ, without requiring complex modifications to the engine speed control system.
[0038] This invention allows older engines with mechanical speed regulation to continue operating without electrification modifications to add electronic speed regulation, thereby reducing customer costs. Furthermore, in oil fields where power grid coverage is not available, and in applications where internal combustion engines are widely used to drive mechanical equipment, this type of gearbox has a large market potential.
[0039] The components in the accompanying drawings of this utility model are for styling reference only and are not specific dimensional standards. The specific dimensions are determined according to the actual production requirements, and the materials of each component can be replaced accordingly based on actual needs.
[0040] All electrical components in this invention are commercially available, conventional equipment known to those skilled in the art. Models can be selected or customized according to actual needs. The setting method, installation method, and electrical connection method can be easily understood by those skilled in the art by following the instructions for use, and will not be described in detail here.
[0041] Working Principle: This novel parallel output gearbox can be externally equipped with two engines, and the output shafts of the two engines can be fixed to the first rotating rod 3 located at the lower left and the third rotating rod 801 located on the left, respectively. When using the gearbox, the engine connected to the first rotating rod 3 can be started, thereby driving the first gear 5 and the first transmission wheel 6 connected to it to rotate via the first rotating rod 3. The second gear 7, which meshes with the two first gears 5, drives the other first gear 5 to rotate, which in turn drives the other first transmission wheel 6 via the first rotating rod 3 fixed to the other first gear 5. This, in turn, drives the external pumping unit and other loads to operate. Simultaneously, the transmission belt sleeved on the two first transmission wheels 6 can assist in the operation of the external pumping unit and other loads. When increased power output is required, the... The engine connected to the third rotary rod 801 starts, thereby driving the second transmission wheel 803 and the second bevel gear 804 connected to it to rotate via the third rotary rod 801. The two third bevel gears 807 meshing with the second bevel gear 804 drive the first bevel gear 802 to rotate, thereby driving the first rotary rod 3 to rotate. This enables the auxiliary external oil pump and other loads to operate and complete parallel operation. The first bevel gear 802, the second bevel gear 804, the support frame 805, the fourth rotary rod 806 and the third bevel gear 807 combine to form a crown gear differential, which allows for a speed difference between the input first transmission wheel 6 on the lower left and the second transmission wheel 803 on the right. This allows the two externally mounted engines to still achieve common power output even when there is a speed difference.
