Abstract
The utility model discloses an internal deceleration friction cylinder, a(less) differential gear reducer is installed inside a friction cylinder to form a new component, a radiator is arranged between the friction cylinder and the roller to form excellent double layer cylinder structure roller, the surface of the friction cylinder is provided with a special rubber block and a press block. The utility model can shorten the length of the transmission unit of friction type oil extractor by 40 to 50 percents so as to arrange the gravity of the utility model more reasonably. The reducer is a shell output, which improves the rigidity of the shaft and improves articulated transmission. The transmission unit is saved of large shaft joint and a pair of bearings, which improves the efficiency by 3 to 5 percents. The utility model has the advantages of small axial direction, large speed ratio, light weight, small size, high efficiency, excellent radiating effect and large bearing capacity.
Description
Technical field: the utility model relates to a kind of oil recovery machiner, particularly a kind of special use of friction type pumping unit and critical component.
Background technique: Chinese patent ZL97217513.X discloses a kind of friction type pumping unit, and it is compared with traditional beam pumping unit, has outstanding features such as energy-efficient, accent ginseng convenience, almost is that other type pumping unit is incomparable.The shortcoming of this machine is that drive path is longer: be made up of break-in motor → coupling → speed reducer → big coupling → friction wheel etc., and the power train axis is vertical with the longitudinal axis of pumping unit, thereby cause machine gravity to depart from the longitudinal axis of this machine, make the stability decreases of this machine and unbalanced to the pressure distribution on ground.
Summary of the invention: the utility model is to overcome friction type pumping unit drive path length and improve the shortcoming of center of gravity away from the longitudinal axis of complete machine, a kind of interior deceleration friction drum is provided, be about to retarder and be placed in friction wheel inside, and the housing of retarder driven cylinder as the power output member and friction wheel rotates, thereby create a brand-new critical component of friction type pumping unit.Interior deceleration friction drum, comprise input shaft, back-up roller bearing, a differential teeth planetary retarder, cylinder, friction wheel, it is characterized in that a differential teeth planetary retarder is arranged on the inside of friction wheel, input shaft connects planetary reducer by hollow shaft, the shell of planetary reducer is a revolving part, shell and cylinder Joint link by radiating fin and friction wheel again.Friction type pumping unit power train shorten length 40～50% can be made it the center of gravity layout and more is tending towards reasonable by the utility model.Retarder changes housing output into, has improved the rigidity of axle, has improved engagement driving, has saved big coupling and pair of bearings in the power train of pumping unit in addition, can raise the efficiency 3～5%.
Retarder in the interior deceleration friction drum adopts a tooth poor (or few tooth is poor) planetary reducer to be imported by eccentric shaft, ring gear (or pin wheel housing) output drives cylinder and rotates, support with radiating fin between cylinder and friction wheel and link, be the double-layer barrel structure, improve heat dispersion.Lubricant oil in the interior deceleration friction drum rotates with cylinder, so flank profil obtains good lubrication, and takes away the heat that bears in the flank profil engagement, thereby improves transmission efficiency and working life.The power feed roll also is equipped with in both sides at friction drum.
In sum, interior deceleration friction drum is the critical component of friction pumping unit, has that speed ratio is big, in light weight, volume is little, efficient is high, a good heat dissipation, advantage such as carrying is big and structure is new.
Description of drawings: Fig. 1 is the structural representation of interior deceleration friction drum.
Fig. 2 is its side view.
Embodiment: input shaft 1 enters a tooth difference by hollow shaft or fewer differential teeth planetary slows down 4, and its shell is a revolving part, and is integral with cylinder 10 concrete mutuallies, and idler is on bearing 3.Friction wheel 8 links by radiating fin 9 and cylinder, and the outer surface of friction wheel is formed band, wheel fastness with flexible band, and power feed roll 2 is equipped with at the two ends of cylinder; Another structure is the block rubber 5 that special formulation is housed on the outer surface of friction wheel 8, have half garden grooving thereon, compress block rubber and (or many) flexible strand composition rope sheave fastness with bolt 7 and briquetting 6, this kind structure is applicable to rope sheave gearing friction wheel, and the friction wheel outer surface of band transmission need not be adorned blob of viscose and briquetting.
