The utility model relates to a differential mechanism for oil field pumping machine, which comprises a shell, a left half shaft, a right half shaft, a left half shaft gear, a right half shaft gear, a cross axle, a planet gear, a rotating shell, a low speed driving taper gear and a low speed driven taper gear. The utility model is characterized in that a brake shell is arranged on the turning shell, at least two driven friction sheets are arranged in the brake shell and a driving friction sheet is arranged between each two driven friction sheets. The driving friction sheet contacts the left half shaft and the right half shaft with friction. A groove is arranged on the turning shell. A spring is arranged in the groove. The spring is pressed against the driving friction sheet and the driven friction sheet to produce friction between the driving friction sheet and the driven friction sheet. The utility model has the advantages that the sliding error of the left half shaft and the right half shaft is effectively removed and the rotate speed of the brake shell and the transmission efficiency of the belt are improved.
Description
One, technical field
The utility model relates to a kind of differential mechanism, relates in particular to a kind of used for oil-field oil pumper differential mechanism.
Two, background technique
The pumping unit that has in the oil field at present adopts two speed reducers to drive the walking beam swing by connecting rod, in order to regulate the differential of two speed reducers, two speed reducers is connected on the differential mechanism; This differential mechanism comprises shell, left half axle, right axle shaft, left half axle gear, right axle shaft gear, cross axle, planetary pinion, rotation shell, low speed drive bevel gear, low speed driven wheel of differential, this differential mechanism is when regulating the differential of speed reducer, left and right half is easy to generate slippage, make between two speed reducers and still have small differential, the connecting rod unbalance stress that speed reducer is driven, thus can not drive the stable work of walking beam.
Three, summary of the invention
At above-mentioned shortcoming, the purpose of this utility model is to improve a kind of used for oil-field oil pumper differential mechanism that can make left and right half not produce slippage.
Technology contents of the present utility model is, a kind of used for oil-field oil pumper differential mechanism, comprise shell, left half axle, right axle shaft, left half axle gear, right axle shaft gear, cross axle, planetary pinion, rotation shell, low speed drive bevel gear, low speed driven wheel of differential, it is characterized in that rotate can on be connected with drag housing, be equipped with at least 2 in the drag housing from movable friction plate, per two from a slice active friction plate being installed, active friction plate and left and right half rubbing contact between the movable friction plate; Fluted on the rotation shell, spring is housed in groove, spring holds out against driving and driven friction plate, makes and produces friction between the driving and driven friction plate.
For the rotating speed of raising drag housing and the efficiency of transmission of belt, a high speed driven wheel of differential is connected with the low speed drive bevel gear, a high speed drive bevel gear links to each other with the high speed driven wheel of differential.
The advantage that the utility model is compared with prior art had is:
1, the utility model can effectively be eliminated the slippage that left and right half produces by the rubbing contact of active friction plate and left and right half.
2, the utility model drives the low speed drive bevel gear by high speed drive bevel gear and high speed driven wheel of differential, can effectively improve the efficiency of transmission of the rotating speed and the belt of drag housing.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, specific embodiment
As shown in Figure 1, a kind of used for oil-field oil pumper differential mechanism, comprise shell 1, left half axle 2, right axle shaft 3, left half axle gear 4, right axle shaft gear 5, cross axle 6, planetary pinion 7, rotate shell 8, low speed drive bevel gear 9, low speed driven wheel of differential 10, it is characterized in that on rotation shell 8, being connected with drag housing 11, be equipped with 4 in the drag housing 11 from movable friction plate 12, from between the movable friction plate 12 a slice active friction plate 13 is installed at per two, active friction plate 13 and left and right half 2,3 rubbing contact; Rotating on the shell 8 flutedly 14, spring 15 is housed in groove 14, spring 15 holds out against driving and driven friction plate 13,12, makes and produces friction between the driving and driven friction plate 13,12; High speed driven wheel of differential 16 is connected with low speed drive bevel gear 9, and high speed drive bevel gear 17 links to each other with high speed driven wheel of differential 16.
During the work of used for oil-field oil pumper differential mechanism, left half axle, right axle shaft 2,3 link to each other with two speed reducers respectively, high speed drive bevel gear 17 is driven by belt by motor, high speed drive bevel gear 17 drives high speed driven wheel of differential 16, by driving low speed drive bevel gear 9 and low speed driven wheel of differential 10, low speed driven wheel of differential 10 drives and rotates shell 8 rotations high speed driven wheel of differential 16 again; When the used for oil-field oil pumper differential mechanism when regulating the speed of two speed reducers, spring 15 holds out against driving and driven friction plate 13,12, makes and produces friction between the driving and driven friction plate 13,12; By the friction between active friction plate 13 and the left and right half, make left and right half 2,3 can not produce slippage again.
