Abstract
The utility model discloses a transmission flexible coupling of a throttle valve used for petroleum drilling. The transmission flexible coupling is arranged between an input shaft of the throttle valve and an output shaft of a driving motor and comprises a left coupling body and a right coupling body, wherein the left coupling body is installed on the output shaft of the motor, and the right coupling body is installed on the input shaft of the throttle valve. The left portions of hinge pins are inserted into holes in the left coupling body, the right portions of the hinge pins are inserted into holes in the right coupling body, vibration reduction sleeves made of flexible materials are arranged between the hinge pins and the right coupling body and/or the left coupling body, the number of the hinge pins is at least three, and the hinge pins are evenly distributed along the circumference. As the transmission flexible coupling is arranged between the output shaft of the driving motor and the input shaft of the throttle valve, if a system vibrates due to faults or other conditions during running, vibration can be buffered through the transmission flexible coupling, vibration and impact of correlation components are reduced, correlation equipment is effectively protected, and the fault rate of the equipment is greatly reduced.
Description
Technical field
The utility model relates to a kind of transmission part, particularly a kind of transmission flexible connection of the throttle valve for oil drilling
Background technique
Oil drilling industry is used throttle valve in a large number, the input shaft of throttle valve joins with the output shaft of controlling motor, during operation, throttle valve data acquisition signal is through A/D conversion, through data processing unit, process again, by central controller output signal, and then drive throttle valve to move through A/D conversion and power amplification and by drive motor.Between the input shaft of throttle valve and the output shaft of motor, be combined into rigidity; there is abnormal or other situation in as excessive in rotation speed change amount, system in service; can make to produce and vibrate or clash between motor output shaft and throttle valve input shaft; the impaired possibility of equipment is large, and use equipment has certain potential safety hazard.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, when operation drive motor and throttle valve between can form and flexibly connect, self-protection associated components, reduce the transmission flexible connection of the throttle valve for oil drilling of equipment failure rate, overcome the deficiencies in the prior art.
The transmission flexible connection of the throttle valve for oil drilling of the present utility model, this flexibility coupling drive is arranged between the input shaft of throttle valve and the output shaft of drive motor, described flexible connection comprises Left-wing Federation's axis body on the output shaft that is arranged on motor and is arranged on the right coupling body on the input shaft of throttle valve, the left part of bearing pin inserts in the hole on Left-wing Federation's axis body, the right part of bearing pin inserts in the hole on right coupling body, the shock-reducing sleeve that has flexible material between bearing pin and right coupling body and/or Left-wing Federation's axis body, at least three described of bearing pins and distributing along even circumferential.
The transmission flexible connection of the throttle valve for oil drilling of the present utility model, is provided with symmetrical groove between wherein said shock-reducing sleeve and right coupling body and/or Left-wing Federation's axis body, and groove is located at the tangent direction of place circumference.
The transmission flexible connection of the throttle valve for oil drilling of the present utility model; owing to having flexible connection between the output shaft at drive motor and the input shaft of throttle valve; if can delay and shake by flexible connection when rotation speed change amount is excessive during operation, system breaks down or vibration occurs other situation; vibration and the shock of associated components have been reduced; effectively protect relevant device, greatly reduced the rate of fault of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A section enlarged diagram shown in Fig. 1.
Embodiment
As shown in Figure 1, 2: 1 is drive motor, the 6th, the throttle valve joining with drive motor.During operation, throttle valve data acquisition signal is through A/D conversion, then processes through data processing unit, by central controller output signal, and then through A/D conversion and power amplification and drive throttle valve to move by drive motor.Between the input shaft of throttle valve 6 and the output shaft of drive motor 1, be provided with flexible coupling drive.This flexible connection comprises Left-wing Federation's axis body on the output shaft that is arranged on motor 12 and is arranged on the right coupling body 5 on the input shaft of throttle valve 6, between each coupling body and axle, by key, is connected.The left part of bearing pin 3 inserts in the hole on Left-wing Federation's axis body 2, the right part of bearing pin 3 inserts in the hole on right coupling body 5, the shock-reducing sleeve 4 that has flexible material between bearing pin 3 and right coupling body 5 and/or Left-wing Federation's axis body 2, the material of shock-reducing sleeve can be flexible rubber preferably or with associated materials like rubber phase.3 at least three of bearing pins and distributing along even circumferential.Between shock-reducing sleeve 4 and right coupling body 5 and/or Left-wing Federation's axis body 2, be provided with symmetrical groove 7, groove 7 is located at the tangent direction of place circumference, and this groove 7 can increase the amount of deformation of shock-reducing sleeve 4.Owing to having flexible connection between the output shaft at drive motor 1 and the input shaft of throttle valve 6; if system breaks down or can be delayed and be shaken by flexible connection when vibration occurs for other situation during operation; vibration and the shock of associated components have been reduced; effectively protect relevant device, greatly reduced the rate of fault of equipment.
