The utility model particularly discloses a visible full-floating lubricating device of a reducer, and solves the problems that the lubricating effect is poor due to lower rotating speed of a conventional lubricating system and the reducer breaks down due to the fact that lubrication cannot be observed. The visible full-floating lubricating device is characterized in that an oil wiper seat is fixed on a tank cover; a connecting rod sliding in the oil wiper seat is arranged in the oil wiper seat in a penetrating manner; a rotating shaft penetrates through the outer end of the connecting rod; an oil wiping plate rotating with an axis of the rotating shaft as a circle center and corresponding to a sight hole cover of the reducer is arranged at the end part of the rotating shaft; a symmetry plane of the oil wiping plate is located on the same plane with the axes of left and right spiral gears, the oil wiping plate is attached to an adjacent surface of the left and right spiral gears; an oil receiving tank is arranged on the inner side of the tank cover below the oil wiping plate; and an oil flowing tank which is communicated with a high-speed bearing, an intermediate bearing and a low-speed bearing and located in the tank cover is formed in the oil receiving tank. According to the visible full-floating lubricating device of the reducer, lubrication of each bearing, particularly lubrication of a drive shaft bearing under low stroke frequency is guaranteed by the pumping unit reducer under the normal circumference, the lubrication effect is higher, and the visible full-floating lubricating device has the advantages of simple structure, convenience in processing and low cost.
Description
Technical field
The utility model relates to the auxiliary device of oil pump speed reducer, is specially the visual full floating lubricating fitting of a kind of retarder.
Background technique
At present, what common beam type reducer of oil-field petroleum-pumping generally adopted is all two-stage shunting formula Double circular arc gear drive retarder, high speed shaft and left-right rotary gear are a pair of high speed level pitch wheel, high speed shaft is axle herringbone tooth generating gear, and left-right rotary gear is divided into a left-handed gear and dextrorotation gear two-part.Jack shaft and herringbone gear are a pair of slow speed turbine stage pitch wheel, and jack shaft is axle herringbone tooth generating gear, and herringbone gear is holistic gear.
Oil pump speed reducer generally all adopts the mode of flooding system lubrication, in block, injects a certain amount of lubricant oil, and driven gear and the certain height of left-right rotary gear are crossed in pasta submergence, utilizes rotatablely moving of gear to provide required lubricant oil for the bearing of retarder.Oil pump speed reducer intermediate bearing and low speed bearing are by being arranged on block junction plane, assembling invisible fixed oil wiper frizing in rear and use lubricates by oil duct, the lubricated general mode that adopts splash lubrication of high speed shaft bearing, when beam-pumping unit jig frequency is during higher than 3 times per minute, the rotating speed of driving shaft will reach the 90-130 per minute right side of turning left, because the part flank of tooth of left-right rotary gear is immersed in lubricant oil, in the time that it runs up, the attached a large amount of lubricant oil of meeting on the flank of tooth, and driving shaft and left-right rotary gear are all helical gears, therefore under the extruding force effect that the lubricant oil on the flank of tooth produces in engagement, get rid of in drive shaft bearing along the direction of helix angle, thereby realize lubricating drive shaft bearing.
But, when oil wiper damage or when frizing measures less than enough lubricant oil intermediate bearing and low speed bearing can not ensure to lubricate, because people in using do not observe just to cause fault.Particularly current most wells is thick oil type oil well, cannot meet the demand in most oil fields according to the rated speed of reducer of oil-field petroleum-pumping, at present the pumping unit majority of oil field operation be operated in per minute 1 forward to per minute 3 in the majority between turning, beam-pumping unit jig frequency reduces the reduction that has caused driving shaft and left-right rotary gear rotational speed, the reduction of rotating speed reduces the oil content of driving shaft and left-right rotary gear, reduce thereby make lubricant oil get into amount in drive shaft bearing, thereby just cannot meet the demand lubricated to drive shaft bearing.
Summary of the invention
The utility model exists lubrication effect poor and cannot observe the problem that causes decelerator trouble in order to solve existing lubrication system because rotating speed is lower, provide a kind of retarder visual full floating lubricating fitting.
The utility model is to adopt following technological scheme to realize: the visual full floating lubricating fitting of retarder, comprise case lid, high-speed bearing, intermediate bearing, low speed bearing and left-right rotary gear, on case lid, be fixed with oil wiper seat, in oil wiper seat, be installed with slip coupling rod in the inner, the outer end of coupling rod is installed with perpendicular and horizontally disposed rotating shaft, it is that rotate and the corresponding oil scraping plate with retarder inspection hole cover position in the center of circle that the end of rotating shaft is provided with its axle center, the axis of the symmetry plane of oil scraping plate and left-right rotary gear is positioned at same plane, and the adjacent surface of oil scraping plate and left-right rotary gear laminating, the case lid inner side of oil scraping plate below is provided with oil-containing groove, on oil-containing groove, be provided with and high-speed bearing, intermediate bearing, low speed bearing is communicated with and is positioned at the stream oil groove of case lid.
Oil wiper seat is arranged on case lid, and coupling rod can be adjusted the position of oil scraping plate, and rotating shaft can ensure floating of oil scraping plate, and the oil of scraping flows to and connects stream oil groove, is assigned to respectively high-speed bearing, intermediate bearing and low speed bearing by stream oil groove.
The installation adjustment of oil wiper is retarder assembling final tache and opens the part that inspection hole cover can be seen at every turn, coupling rod can be along the axial direction adjustment of left-right rotary gear, make oil scraping plate and left-right rotary gear gapless tangent, rotating shaft can make oil scraping plate and left-right rotary gear remain tangent and not interfere.Having overcome existing lubrication system exists lubrication effect poor and cannot observe the problem that causes decelerator trouble because rotating speed is lower.
The utility model has been realized oil pump speed reducer with ensureing in the ordinary course of things the lubricated of each bearing, particularly drive shaft bearing lubricated under low jig frequency, and lubrication effect is higher, have advantages of simple in structure, easy to process and with low cost.
Concrete beneficial effect is as follows: 1, not design flow oil groove of junction plane, and how long complete machine use can not form greasy dirt yet affects environment; 2, from design upper reaches oil groove energy distribute lubrication oil to output shaft bearing, midship shaft bearing and bearing of input shaft; 3, after retarder assembling, refill and join oil wiper and can adjust at any time; 4, oil wiper be arranged on case lid with middle left-right rotary gear in directly over, forward reversion apart from identical, has the identical oil mass of scraping with pasta while turning to difference; 5, oil wiper is arranged on case lid and is zero distance with left-right rotary gear and is to float, and is positioned at the outside of gear.
