Description

Technical Field

[0001] The utility model relates to the technical field of speed regulating equipment, in particular to a diesel engine oil pump speed regulator with a correction component. Background Art

[0002] In order to meet the characteristic requirements of diesel engines, mechanical speed governors are generally equipped with correction mechanisms. Existing correction mechanisms usually adjust the preload of the spring through a threaded connection, such as the patent with announcement number CN2316468Y. Generally, there are several problems: (1) The threaded adjustment method cannot accurately grasp the adjustment length, resulting in a cumbersome installation process; (2) It is necessary to reserve installation and adjustment windows, which increases the difficulty of shell processing. Utility Model Content

[0003] In order to solve the problem that the installation process of the threaded adjustment correction mechanism in the prior art is relatively complicated, the utility model provides a diesel engine oil pump speed regulator with a correction component which is easy to install.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A diesel engine oil pump speed governor with a correction component,

[0006] A flyweight component and a tension component are arranged in the housing;

[0007] A speed regulating component, wherein the speed regulating component can rotate toward the tension component under the action of the flyweight component;

[0008] The stabilizer component is arranged on the side of the tension component away from the speed regulating component:

[0009] A correction component, the correction component includes a top shaft slidably set in the guide hole of the tension component and a top block set at the end of the top shaft close to the speed regulating component, a correction spring is provided between the top block and the tension component, the top shaft is tightly set against the stabilizer component, and a limiting mechanism for limiting the distance between the top block and the tension component is provided at the end of the top shaft away from the top block.

[0010] Furthermore, a slot is provided on the top shaft, and the limiting mechanism includes a clamping ring arranged in the slot. The position of the top shaft is directly limited by the clamping ring, which is convenient for positioning without reserving an installation window.

[0011] Furthermore, the position limiting structure further comprises a washer disposed between the clamping ring and the tension member. The washer can adjust the position of the top shaft to meet different requirements.

[0012] Furthermore, the tension component is a sheet metal part, and the guide hole is provided on the bottom plate of the sheet metal part.

[0013] Furthermore, one end of the correction spring is provided with a first plane for contacting the top block, and the other end of the correction spring is provided with a second plane for contacting the tension member. The spring is supported by contacting the top block and the tension member through the plane, which can maintain the distance between the top block and the tension member, reduce the oblique force generated on the top block, and maintain the verticality between the top shaft and the tension member.

[0014] Furthermore, a ring cap is provided at one end of the top block close to the correction spring, and the inner diameter of the ring cap is in clearance with the outer diameter of the correction spring. The ring cap cooperates with the correction spring to further limit the top shaft.

[0015] Furthermore, the ring cap is located at the edge of the top block. In this way, the contact area between the correction spring and the top block is larger, thereby increasing the supporting capacity.

[0016] Furthermore, a concave circular groove is formed by stamping the bottom of the tension component, and the inner diameter of the circular groove is in clearance with the outer diameter of the correction spring. The circular groove cooperates with the spring to further limit the top shaft.

[0017] Furthermore, the guide hole is located at the center of the circular groove.

[0018] Furthermore, the end surface of the top block away from the tension member is an arc surface, and the circle of the arc surface coincides with the center line of the top shaft. The end surface of the top block is set as an arc surface, which can make the force of the top block roughly along the center of the top shaft, further reducing the oblique force borne by the top shaft.

[0019] Beneficial effects:

[0020] (1) The top shaft of the diesel engine oil pump speed regulator with correction components of the utility model is provided with a limit mechanism, which is convenient for installation;

[0021] (2) No need to reserve installation and debugging windows, reducing the difficulty of shell processing;

[0022] (3) The tension component is a sheet metal part, which is easy to process, simple in structure and cost-saving;

[0023] (4) A hole is opened on the sheet metal as a guide hole for the top shaft, and the two ends of the correction spring are set as flat surfaces. In addition, a groove is provided between the top block and the tension component for the end of the correction spring to extend into and cooperate with. Therefore, in addition to providing a correction preload, the correction spring can also maintain the overall position accuracy of the top block and the top shaft, and will not easily cause the top shaft to shift. The position accuracy of the top block and the top shaft is guaranteed, which can further ensure the normal operation of the spring without compression deviation. Therefore, the top shaft, the top block and the spring support and limit each other to ensure the overall position and movement accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
