The utlity model has following beneficial effect: this speed reducer drainage self-seal device is owing to adopt end bracket enclosed cover below that gathering room is arranged, the end bracket enclosed cover is bolted on the bearing cap, sealing gasket places between end bracket enclosed cover and the bearing cap, dust-proof seal ring places in the end bracket enclosed cover endoporus, and contact with input and output shaft, flinger ring is fixed on right-hand member in the end bracket enclosed cover, be filled with respectively stuffing box packing in the groove on the flinger ring external diameter and in the groove in the endoporus, spiral oil scraping plate spiral is fixed on the input and output shaft, the oil return bolt is connected to the deceleration box of end bracket enclosed cover below, have in the oil return bolt with gathering room and deceleration box in the structure of the oil duct that communicates.Utilize spiral oil scraping plate, flinger ring gear oil, utilize gathering room and the drainage of oil return bolt to dredge leakproof.It is outside to axle head that spiral oil scraping plate, flinger ring make the gear oil that overflows be thrown in the end bracket enclosed cover Leakage prevention when axle rotates, and be back to gathering room along end bracket enclosed cover inwall, the gear oil of secondary back is sent the speed reducer fuel tank back to by the oil return bolt, fundamentally solved the difficult problem of speed reducer leakage of oil, make the sealing of speed reducer by original easily damaged parts, become the parts suitable with integral device working life, both environmental protection had economy, more be convenient to the production management in well site, and simple in structure, safe, energy-conservation, environmental protection.The input that this speed reducer drainage self-seal device can the effective sealing speed reducer thus, the characteristics of output shaft end.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
1-bearing cap among the figure, 2-sealing gasket, 3-end bracket enclosed cover, 4-dust-proof seal ring, 5-input and output shaft, 6-spiral oil scraping plate, 7-flinger ring, 8-oil return bolt, 9-gathering room, 10-oil duct.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing, this speed reducer drainage self-seal device comprises bearing cap 1, sealing gasket 2, end bracket enclosed cover 3, dust-proof seal ring 4, input and output shaft 5, spiral oil scraping plate 6, flinger ring 7 and the oil return bolt 8 that is fixed on the deceleration box.There is gathering room 9 end bracket enclosed cover 3 belows, end bracket enclosed cover 3 is bolted on the bearing cap 1, sealing gasket 2 places between end bracket enclosed cover 3 and the bearing cap 1, dust-proof seal ring 4 is fastened in end bracket enclosed cover 3 endoporus by the groove on the external diameter, and contact with input and output shaft 5, flinger ring 7 is connected to end bracket enclosed cover 3 interior right-hand members, be filled with respectively stuffing box packing in the groove on flinger ring 7 external diameters and in the groove in the endoporus, spiral oil scraping plate 6 spirals are fixed on the input and output shaft 5, oil return bolt 8 is connected to the deceleration box of end bracket enclosed cover 3 belows, have in the oil return bolt 8 with gathering room 9 and deceleration box in the oil duct 10 that communicates.Described input and output shaft 5 refers to input shaft and the output shaft on the speed reducer, and this speed reducer drainage self-seal device is installed respectively on input shaft and output shaft.O-ring seals is adopted in described stuffing box packing.
During actual the use: this speed reducer drainage self-seal device bearing cap 1 adopts clamping bolt with sealing gasket 2 and end bracket enclosed cover 3, oil return bolt 8 is connected, end bracket enclosed cover 3 and input and output shaft 5 are by dust-proof seal ring 4, flinger ring 7 isolation, form gathering room 9, from bearing cap 1, the gear oil that overflow at place, input and output shaft 5 slits is thrown on end bracket enclosed cover 3 inwalls when input and output shaft 5 rotates through spiral oil scraping plate 6, and be back in the gathering room 9 along end bracket enclosed cover 3 inwalls, the gear oil that secondary is collected flows back in the Gearbox through gathering room 9 and the 10 unobstructed ground secondaries of the oil duct on the oil return bolt 8 of end bracket enclosed cover 3, thereby plays the self-packing effect of speed reducer drainage.
This speed reducer drainage self-seal device is revealed reason for speed reducer on the basis that does not change former gearbox structure, determined improved two principles of sealing configuration, i.e. drainage and dredging.Drainage is exactly to manage to make the gear oil that overflows from axle head to be thrown to end bracket enclosed cover 3 interior Leakage preventions to the axle head outside when axle rotates through spiral oil scraping plate 6, flinger ring 7, and be back in the gathering room 9 along end bracket enclosed cover 3 inwalls, eliminate that or shaft end seal unbalanced by external and internal pressure lost efficacy and the gear oil that causes is revealed.Dredge is exactly to make can to flow back in the Gearbox by unobstructed ground secondary by the oil of seepage outside axle head.
The input, the output shaft end that have solved oil pumping unit reduction gearbox adopt seal with elastometic washer, move in the dust storm in the open air for a long time, cause seal failure, cause the speed reducer leakage of oil, increase the weight of the wearing and tearing of gear, increase the problem of the loss of gear oil, and then the normal operation of assurance equipment and well site environment.
