Abstract
The utility model belongs to the oil extraction machinery, in particular to a hollow decelerator provided with moveable teeth, used to solve the problems that the oil pipe is tightly blocked, the oil pipe is disconnected and the oil pipe drops into the well. The utility model comprises an upper joint (1), a clip spring (6), a nut (16), a first bearing (10) and a second bearing (11). An eccentric shaft (2) which is provided with a shaft housing (8) is movably arranged in the upper joint (1); a plurality of rollers (7) which roll on the envelope curve (16) in fixed teeth are arranged outside the shaft housing (8); the rollers are movably arranged on an oscillating tooth carrier (9); flow passages (15) are respectively arranged in the centers of the eccentric shaft (2) and the oscillating tooth carrier (9) and are communicated with each other. With big transmission ratio, small size and great strength, the decelerator is particularly applicable for small rooms and pipelines.
Description
Technical field
The utility model belongs to oil recovery machiner equipment, and oil pipe is stuck in particularly a kind of processing oil recovery process, the hollow movable teeth reducer that oil pipe is disconnected to be taken off, oil pipe falls well.
Background technique
At present, most of oily vapour field often occurs that oil pipe is stuck, oil pipe disconnectedly takes off, oil pipe falls accidents such as well, cause oil gas field stopping production overhaul, have a strong impact on the oil recovery economic benefit, so anxious must a kind of underground hydraulic pressure back-off device of development, the deceleration that particularly can realize large speed ratio in certain cylindrical space increases turns round device.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of, oil pipe stuck at the oil recovery process oil pipe disconnectedly to take off, oil pipe falls well, can realize the hollow movable teeth reducer that the deceleration of large speed ratio is reversed in certain cylindrical space.
The technological scheme that the utility model technical solution problem adopts is: a kind of hollow movable teeth reducer of being made up of upper connection, jump ring, back of the body cap and bearing one, two, be characterized in upper connection, adorning versatilely an eccentric shaft, adorn an axle sleeve on the eccentric shaft, axle sleeve is equipped with a plurality of rollers outward, rolls on the envelope curver of roller in permanent tooth; Roller is contained on the movable teeth rack versatilely; Eccentric shaft is equipped with flow channels with the movable teeth rack center and communicates.
The beneficial effects of the utility model are: this retarder velocity ratio is big, and volume is little, and the intensity height is adapted to especially that the space is little, uses in the pipeline environment.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.

Embodiment
With reference to accompanying drawing, a kind of hollow movable teeth reducer, the hollow movable teeth reducer of forming by upper connection 1, jump ring 6, back of the body cap 16 and bearing one, 2 10,11, be characterized in upper connection 1, adorning versatilely an eccentric shaft 2, adorn an axle sleeve 8 on the eccentric shaft 2, outside the axle sleeve 80 rollers 7 are housed, roll on the envelope curver 16 of roller 7 in permanent tooth; Roller 7 is contained on the movable teeth rack 9 versatilely; Eccentric shaft 2 is equipped with flow channels 15 with movable teeth rack 9 centers and communicates.Movable teeth rack 9 is equipped with bearing 2 11 and back of the body cap 14, between back of the body cap 14 and the movable teeth rack 9 cushion rubber 4 13 is housed, back of the body cap 14 external application screw threads are connected with permanent tooth 5, between permanent tooth 5 and the upper connection 2 cushion rubber 1 is housed, between upper connection 1 eccentric shaft 2 cushion rubber 24 is housed, bearing 1 and cushion rubber 3 12. are housed between eccentric shaft 2 right-hand members and movable teeth rack 9
When hollow movable teeth reducer is worked, eccentric shaft 2 is realized eccentric rotation for input shaft by axle sleeve 8, extruding roller 7, form the motion of difference tooth, roller 7 rolls on permanent tooth 5, drives movable teeth rack 9 rotations, eccentric shaft 2 whenever revolves and turns around, gap of roller 7 rotation, so the number of roller 7 is velocity ratio, this retarder reduction speed ratio is big.
Claims (2)
1. hollow movable teeth reducer, form by upper connection (1), jump ring (6), back of the body cap (16) and bearing one, two (10), (11), it is characterized in that in upper connection (1), adorning versatilely an eccentric shaft (2), adorn an axle sleeve (8) on the eccentric shaft (2), the outer a plurality of rollers (7) that are equipped with of axle sleeve (8), the envelope curver (16) of roller (7) in permanent tooth gone up and rolled; Roller (7) is contained on the movable teeth rack (9) versatilely.
2. hollow movable teeth reducer according to claim 1 is characterized in that eccentric shaft (2) is equipped with flow channels (15) with movable teeth rack (9) center and communicates.
