Abstract
The utility model relates to a one-way-rotation clutch comprising an outer clutch ring, an inner clutch ring, a pawl, a pawl shaft and a magnet, wherein the pawl is provided with a ratchet end and a tail end far away from the ratchet end, and the pawl is installed on the outer clutch ring by the pawl shaft; the magnet and the tail end of the pawl are oppositely fixed on the outer clutch ring; and the ratchet is arranged on the inner clutch ring. The one-way-rotation clutch has the beneficial effects the structure is simple, the pawl is fixed on the outer clutch ring, the ratchet is arranged on the inner clutch ring; due to the rotation of the inner ring, the ratchet end of the pawl is meshed with the ratchet on the inner clutch ring; and when the rotating speed of the outer ring is higher than that of the inner ring, the one-way-rotation clutch realizes the exceeding phenomenon.
Description
Technical field
The utility model relates to a kind of clutch, relates in particular to a kind of one-way rotation clutch that is used for oil field equipment.
Background technique
The oil field equipment normally transmission system through beam pumping unit is connected with the down-hole transmission system and realizes the oil recovery purpose; But meeting that transmission system stops or down-hole pressure is higher than aboveground driving force and will produces that downhole electrical motor is counter to drag aboveground motor; Cause aboveground motor counter-rotating; The then aboveground motor of aboveground motor counter-rotating begins generating, can cause oil recovery not carry out normally thus, and therefore a kind of new one-way rotation clutch that is used for oil production equipment need be provided.
Summary of the invention
The purpose of the utility model is to propose a kind of one-way rotation clutch that is used for oil field equipment, and the ratchet of this clutch is installed on the clutch outer shroud; Magnet is fixed on the clutch outer shroud; Ring is provided with ratchet in the clutch.The one-way rotation clutch of the utility model is used for the counter-rotating that oil field equipment can prevent aboveground motor, avoids the counter-rotating generating of aboveground motor.
The utility model solves the technological scheme that its technical problem adopted: a kind of one-way rotation clutch; Comprise ring, ratchet, pawl axis, magnet in clutch outer shroud, the clutch; Described ratchet has ratchet end and away from the tail end of ratchet end, said ratchet is installed on the said clutch outer shroud through said pawl axis; The tail end of said magnet and said ratchet is relatively fixed on the clutch outer shroud; Ring is provided with ratchet in the described clutch.
Described clutch outer shroud is processed by non-magnet_conductible material.
Described magnet is directly installed on the described clutch outer shroud.
Described magnet is a cylindrical body.
The beneficial effect of the utility model is: simple in structure; Ratchet is fixed in the clutch outer shroud; Ring is provided with ratchet in the clutch, rotates through the moving outer shroud of interior endless belt, and interior ring can directly be connected with motor shaft; The ratchet end of ratchet is meshed with the ratchet that clutch is interior to be encircled, and realizes surmounting phenomenon when in the outer shroud rotating speed is higher than, encircling.In aboveground and down-hole oil pumping process; Meet and shut down or down-hole pressure when surpassing aboveground motor and actively being worth; Surmount phenomenon the time of pumping unit up-down stroke is changed along with the change of system loading, it is poor because of the work phase time that elastic problem produces to have remedied ground system and underground system, transient equiliblium mechanically the interference phenomenon of pumping unit downhole system and ground system; Improved the working state of down-hole pump valve effectively, can not cause the motor counter-rotating because of the down-hole pumping unit.
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed description.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to Fig. 1; A kind of one-way rotation clutch; Comprise ring 2, ratchet 3, pawl axis 4, magnet 5 in the clutch outer shroud 1, clutch, described ratchet has ratchet end 6 and away from the tail end 7 of ratchet end, said ratchet is installed on the said clutch outer shroud through said pawl axis; The tail end of said magnet and said ratchet is relatively fixed on the clutch outer shroud; Ring is provided with ratchet 8 in the described clutch.Ratchet is fixed in the clutch outer shroud; Ring is provided with ratchet in the clutch, rotates through the moving outer shroud of interior endless belt, and interior ring can directly be connected with motor shaft; The ratchet end of ratchet is meshed with the ratchet that clutch is interior to be encircled, and realizes surmounting phenomenon when in the outer shroud rotating speed is higher than, encircling.In aboveground and down-hole oil pumping process; Meet and shut down or down-hole pressure when surpassing aboveground motor and actively being worth; Surmount phenomenon the time of pumping unit up-down stroke is changed along with the change of system loading, it is poor because of the work phase time that elastic problem produces to have remedied ground system and underground system, transient equiliblium mechanically the interference phenomenon of pumping unit downhole system and ground system; Improved the working state of down-hole pump valve effectively, can not cause the motor counter-rotating because of the down-hole pumping unit.
In the present embodiment, described magnet is directly installed on the described clutch outer shroud.
In the present embodiment, described magnet is a cylindrical body.
In the present embodiment, described clutch outer shroud is processed by non-magnet_conductible material.
According to the clutch of the utility model, ratchet is arranged at the clutch outer shroud, through the rotation of interior ring, the ratchet end of ratchet and the ratchet on the interior ring are meshed, realize surmounting phenomenon when in the outer shroud rotating speed is higher than, encircling, thereby realize the one-way rotation of clutch.
