Abstract
The utility model relates to an anti-deflection friction stuffing box, belonging to the manufacturing technology field of the mechanical equipment in the oil field, which comprises a box body, a gland and a gram. A guiding device is arranged between the box body and the gland, and the guiding device comprises an upper disc, a lower disc and three rolling axles. An oil pumping rod is penetrated through a triangle enclosed by the box body, the gland, a guiding hole and three rolling axles, the moving route of the oil pumping rod is controlled through an upper guiding disc and a lower guiding disc to prevent the oil pumping rod from being deflected in the movement process, the rolling friction is formed between the rolling axle and the oil pumping rod, between the rolling axle and the upper disc, between the rolling axle and the lower disc, and between adjacent rolling axles, the attrition rate of parts is low, and no damage to the oil pumping rod exists. The utility model controls the moving route of the oil pumping rod through a guiding device, the friction between the oil pumping rod and the gland is prevented effectively, the structure is simple, and the performance is reliable.
Description
Technical field:
The utility model belongs to OFME manufacturing technology field, is a kind of packing box.
Background technology:
Packing box is parts of oil pumper, mainly constitute by box body, gland and leather orchid, box body is a tubular body, gland is equipped with at two ends respectively up and down, there is through hole at the gland center, the leather orchid is a sealing device, near the gland place, sucker rod passes gland and box body, pumps during work at the inboard two ends of box body, desirable state is that sucker rod is along box body and gland axe movement, do not contact with gland, but sucker rod can be offset during actual motion, produce sliding friction with gland, sucker rod easy to wear increases the resistance of motion simultaneously.
Summary of the invention:
The technical problems to be solved in the utility model is to disclose a kind ofly can guide the sucker rod moving line, prevents to produce between sucker rod and the gland the anti-eccentric wear packing box of friction.
The scheme of the utility model technical solution problem is between box body and gland guider to be housed, guider is made of last dish, lower wall and three roller bearings, last dish and lower wall are to being buckled together, internal edge is evenly placed three roller bearings, roller bearing is the Pear-Shaped that waist is arranged, or is described as dumb-bell shape, and three roller bearings are triangular in shape among last dish and lower wall, the center of last dish and lower wall has pilot hole respectively, and pilot hole is corresponding with the through hole of gland.Pass between the triangle that sucker rod surrounds from box body, gland and pilot hole and three roller bearings, two positioning disks are controlled the sucker rod moving lines up and down, prevent to be offset in the sucker rod motion process, between roller bearing and the sucker rod, be rolling friction between roller bearing and last dish and lower wall, the adjacent roller bearing, the component wear degree is low, and is harmless to sucker rod.
The utility model is controlled sucker rod motion circuit by guider, prevents the friction between sucker rod and the gland effectively, and is simple in structure, dependable performance.
Description of drawings:
Fig. 1 is the utility model sectional view;
Fig. 2 is the schematic diagram of roller bearing and lower wall part.
The specific embodiment:
The utility model is made of box body 1, gland 2 and leather blue 3, between box body 1 and gland 2, guider 4 is housed, guider 4 is made of last dish 5, lower wall 6 and three roller bearings 7,6 pairs of last dish 5 and lower walls are buckled together, internal edge is evenly placed three roller bearings 7, and roller bearing 7 is for there being the Pear-Shaped of waist, and three roller bearings 7 are triangular in shape among last dish 5 and lower wall 6, the center of last dish 5 and lower wall 6 has pilot hole 8 respectively, and pilot hole 8 is corresponding with the through hole of gland 2.
