Abstract

The utility model relates to a leakage blocking cover plate for an output shaft of a pumping unit reduction box. The leakage blocking cover plate for the output shaft of the pumping unit reduction box is characterized in that the leakage blocking plate is formed by axially and symmetrically combining two semicircular cover plates; and bolt holes are circumferentially arranged at and end face. The leakage cover plate for the output shaft of the pumping unit reduction box is applied in pumping units, is reliable in sealing effect, and can perform the corresponding regulations according to the wearing condition of sealing fillers in a using process, so that the requirement of blocking leakage for a long time is achieved. The leakage blocking cover plate is simple in structure and convenient in operation, popularization and application, and can be massively machined as the accessories of pumping units.

Description

Oil pumping unit reduction gearbox output shaft leak stopping cover plate
Technical field
The utility model relates to oil pumping unit reduction gearbox output shaft leak stopping cover plate.
Background technique
Oil pumping unit reduction gearbox output shaft oil leakage phenomenon is very general, is a great problem of pumping unit equipment control always.Because the leakage of lubricant oil needs continuous supply lubricant oil to keep equipment and runs well, and causes the lubricant oil waste very big.Simultaneously, can bring heavy cleaning after lubricant oil leaks to production, bring pollution to surrounding environment, leak when serious even can cause speed reducer internal gear, bearing, lubrication effect difference and damaging because of oil starvation.At present, for pumping unit output shaft oil leakage phenomenon, on-the-spot solution commonly used has two kinds: 1, tear go back to machine maintenance department open and carry out overall maintenance, change the oil sealing of wearing and tearing, but it is too high to do cost like this, workload is huge; 2, with felt leak is carried out shutoff, its leak stopping effective date is short, and sealing effect is poor.
Summary of the invention
For solving the problem of pumping unit plugging effect difference in the produced on-site, the utility model provides a kind of oil pumping unit reduction gearbox output shaft leak stopping cover plate.This leak stopping cover plate can effectively seal for the leakage of oil problem of oil pumping unit reduction gearbox output shaft, prevents the oil leak in the speed reducer.
The utility model is for solving its technical problem, and the technological scheme that is adopted is:
Oil pumping unit reduction gearbox output shaft leak stopping cover plate is characterized in that: it is involuted by two semi-annular cover plates of axial symmetry, and end face is circumferentially laid bolt hole.
Press such scheme, endoporus and oil pumping unit reduction gearbox output shaft that said two semi-annular cover plates involute are Spielpassung.
Press such scheme, the inner periphery of said semi-annular cover plates is provided with downward flange, and the radial thickness of said flange is slightly less than the width of oil seal groove.
Press such scheme, said two semi-annular cover plates link to each other with screw through the end face connecting plate that both sides are provided with.
Press such scheme, said bolt hole matches with end cap tapped hole on being laid in the output shaft end cap, and the elasticity through bolt is regulated leak stopping cover plate and output shaft end cap compresses packing and reach, and realizes the purpose that seals.
Press such scheme, said two semi-annular cover plates are provided with 2-4 and the corresponding bolt hole of end cap tapped hole, also are provided with 2 tapped holes that match with the end face connecting plate simultaneously.
During use; Two semi-annular cover plates of axial symmetry are stuck in outside the oil pumping unit reduction gearbox output shaft; Adopt connecting plate that this two-part cover screw is connected into a complete cover plate, in oil seal groove, lay stuffing box packing then after, with bolt the leak stopping cover plate is fixed on the oil pumping unit reduction gearbox output shaft end cap; Elasticity through regulating between leak stopping cover plate and the output shaft end cap guarantees plugging effect, prevents the lubricant oil leakage.Use a period of time, after the stuffing box packing wearing and tearing, can compress packing through the elasticity between bolt leak stopping cover plate and the output shaft, and prevent oil seepage in the oil pumping unit reduction gearbox.
The beneficial effect of the utility model:
(1) this oil pumping unit reduction gearbox output shaft leak stopping cover plate is applied in the pumping unit, and sealing effect is reliable, and can adjust accordingly according to the abrasion condition of stuffing box packing in the using process, reaches the requirement of long-time leak stopping.From the pumping unit test situation, after this device leak stopping was installed, by the end of so far, the phase that effectively seals had reached 800 days, and sealing effect is still fine;
(2) simple in structure, easy to operate, can be used as pumping unit accessory batch process, easy to utilize.

Embodiment
Below in conjunction with accompanying drawing and embodiment the summary of the invention of this model utility is described further.
Oil pumping unit reduction gearbox output shaft leak stopping cover plate; It comprises two the axially semi-annular cover plates (1) and the connecting plates (3) of symmetry; Be laid with 2 unthreaded holes on the said connecting plate; The two end part of said semi-annular cover plates respectively are laid with the tapped hole that is complementary with it, are combined tapped hole and the connecting plate laid through its end two semi-annular cover plates and adopt retaining screw (2) screw to be formed by connecting, and are Spielpassung between endoporus that involutes and the output shaft (6); The periphery of endoporus is provided with downward flange; The radial thickness of flange is slightly less than the width of oil seal groove (8), and the non-end of said semi-annular cover plates evenly is laid with 3 bolts hole, goes up the end cap tapped hole (9) that is provided with output shaft end cap (7) and matches; Regulate bolt (4) through regulating the elasticity between leak stopping cover plate and the output shaft, the stuffing box packing in the chucking oil seal groove.
During use; Two semi-annular cover plates of axial symmetry are stuck in outside the oil pumping unit reduction gearbox output shaft; Adopt connecting plate that this two-part cover screw is connected into a complete cover plate, in oil seal groove, lay stuffing box packing (5) then after, with the adjusting bolt leak stopping cover plate is fixed on the output shaft end cap; Guarantee plugging effect through elasticity to the no seepage and no leakage of regulating between leak stopping cover plate and the output shaft end cap again, prevent the lubricant oil leakage.Use a period of time, after the stuffing box packing wearing and tearing, can compress packing through the elasticity of regulating between leak stopping cover plate and the output shaft, and prevent oil seepage in the oil pumping unit reduction gearbox.
