Abstract
The utility model provides an input shaft sealer of the reduction gearbox of a plateau oil pumping unit, belonging to a sealing device. The sealing device comprises a sealing pot provided with a flange disc, wherein sealing packing is arranged in the sealing pot; a pressure sleeve outside the sealing packing is arranged in the sealing pot; a pressure cap outside the pressure sleeve is fixed on the sealing pot through threads; a mounting hole is arranged in the flange disc. Through rotating the pressure cap of the sealer to push forward the pressure sleeve, the clearance of the sealing packing can be adjusted to press the sealing packing close to the position to be sealed, so the sealing effect is good, oil is not easy to leak, the damage to the reduction gearbox is reduced, and the service life of the reduction gearbox is lengthened.
Description
Technical field
The utility model provides a kind of seal arrangement, the seal arrangement on especially a kind of oil pumping unit reduction gearbox.
Background technique
At present, plateau oil pumping unit reduction gearbox input shaft adopts the oil sealing mode to seal, and seal clearance is non-adjustable, and its sealing effect is poor, very easily leakage of oil, and speed reducer is short working life, causes pumping unit to damage when serious easily.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of plateau oil pumping unit reduction gearbox input shaft sealer is provided, and to improve its sealing effect, prolongs speed reducer working life.
The utility model is to realize like this, plateau oil pumping unit reduction gearbox input shaft sealer, it has the sealing drum of flanged dish, stuffing box packing is housed in the sealing drum, the stuffing box packing outside has clamping sleeve to be installed in the sealing drum, clamping sleeve has pressure cap to be installed on the sealing drum by screw thread outward, and mounting hole is arranged on the flange plate.
Adopt the sealer of said structure, the rotation pressure cap promotes the gap that the clamping sleeve reach can be adjusted stuffing box packing, makes stuffing box packing press close to sealed position, good sealing effect, and not easy oil leakage has reduced the speed reducer damage, has prolonged the working life of speed reducer.
Description of drawings
Fig. 1 is the schematic representation of the utility model structure.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model.
As shown in drawings, the plateau oil pumping unit reduction gearbox input shaft sealer of the utility model, it has the sealing drum 3 of flanged dish 4, stuffing box packing 6 is housed in the sealing drum, the stuffing box packing outside has clamping sleeve 1 to be installed in the sealing drum, clamping sleeve has pressure cap 2 to be installed on the sealing drum outward, and mounting hole 8 is arranged on the flange plate.
When the speed reducer input shaft sealer of this structure uses, by construction bolt in the mounting hole on flange plate sealing drum is fixed on the speed reducer casing 5, stuffing box packing is filled in the space between input shaft 7 and the sealing drum, and clamping sleeve inserts in the sealing drum, and the rotation pressure cap is installed on the sealing drum.When screwing pressure cap, can promote the clamping sleeve reach, make it apply suitable pressure, make stuffing box packing press close to sealed position, reach good sealing effect stuffing box packing.
Brake axle on the speed reducer and input shaft are same axle, and therefore, the sealer of the utility model also can be used for the sealing of brake axle.
Stuffing box packing can be packing or asbestos rope.
