Abstract
The utility model relates to a fuel injection pump mechanical governor fine setting operating mechanism, the position of its operating handle (8) is adjusted through adjusting nut (2) on hook screw (4). The cylinder of the elbow of the hook-shaped screw rod (4) is directly matched with the cylinder hole on the control handle (8), the hook-shaped screw rod is arranged in the U-shaped groove of the bracket (1), and the adjusting nut (2) is arranged at the outer side of the bracket (1) at the right end of the hook-shaped screw rod (4) and can be finely adjusted and quickly adjusted. The mechanism has simple and reliable structure and convenient processing, overcomes the defect that the fine adjustment mechanism slides due to vibration of a high-power diesel engine, and can be applied to mechanical speed regulators of B-type and P-type injection pumps of 135 series diesel engines with cylinder expansion.
Description
Technical field
The utility model relates to Injection Pump mechanical governor assembly, particularly Injection Pump mechanical governor fine setting operating mechanism.
Background technique
At present, 135 series contain and expand cylinder diesel and be divided into long-range handle (up-set type, underneath type or two-purpose) up and down and trimming handle etc. with the operating mechanism of Injection Pump mechanical governor.The structure of its trimming handle is a unsteady worm-and-wheel gear, relies on spring force that worm screw is pressed on worm gear (the claiming sector rack again) flank of tooth, and rotary worm changes the position at Joystick relative worm gear center (being the control lever shaft center), to reach the purpose of adjusting.Because diesel engine improved power for adapting to market demand by expanding measures such as cylinder, increasing stroke in recent years, thereby the reliability requirement to the operating mechanism of speed regulator is more and more higher, former trimming handle relies on spring force pressure always to lock the requirement that can not adapt to high-power diesel engine, often glide the poor reliability of work voluntarily during generation work.
Summary of the invention
For overcoming above-mentioned defective, the utility model provides the reliable Injection Pump mechanical governor fine setting of a kind of performance simple in structure, easy to process operating mechanism, guarantees reliable operation.
Structure of the present utility model is such, and Injection Pump mechanical governor fine setting operating mechanism is made up of Joystick (8), support (1), hook-type screw rod (4) etc.Wherein Joystick (8) is that original common underlying remote control handle is replenished cylindrical hole of processing, support (1) is that a block plate bends to " L " shape, at one end have " U " shape groove, one end of hook-type screw rod is that a cylindrical body bends to 90 °, there is a positive stop lug boss (pad welding) centre, and head has the aperture of dress cotter pin, respective aperture on its cylindrical diameter and the Joystick (8) is Spielpassung, the internal thread of the outside thread of the other end screw rod and adjusting nut, locking nut is movingly, is provided with circlip groove at screw rod tail.The lever shaft plug screw (11) and the pasta plug screw (7) of former speed regulator are respectively increased a screw, support (1) is fixed on plug screw (7) by screw (10) and (11) go up and governor housing fuses, debug joint nut (2) on the hook-type screw rod (4), locking nut (3), the cylinder elbow is packed in the respective aperture of Joystick (8), shell tool (5), fixing with cotter pin (6), the hook-type screw rod places " U " shape groove of support (1), adjusting nut (2) is in the outside of hook-type screw rod (4) right-hand member support (1), when needs are adjusted working state, as long as rotation adjusting nut (2) can spur the purpose that Joystick (8) makes it to reach around the control lever shaft rotation fine setting.For preventing to become flexible, available locking nut (3) is pieced together tight.In the time Joystick (8) rapid adjustment need being arrived new position, only need nut (2) or (3) are unclamped, hook-type screw rod (4) is lifted from " U " shape groove of support (1), pull Joystick (8), can between staking-out work point and idling point, any suitable location stop, then hook-type screw rod (4) is returned in " U " shape groove of support (1), adjusts to the outer side surface of support (1), use locking nut (3) to screw at last and get final product adjusting nut (2).The more former trimming handle of the utility model is simple in structure, and is easy to manufacture, reliable performance.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.Fig. 1 is the utility model example plan view, Fig. 2 is the utility model example plan view, among the figure: 1, support 2, adjusting nut 3, locking nut 4, hook-type screw rod 5, faced washer 6, cotter pin 7, pasta plug screw 8, Joystick 9, axle-steel silk back-up ring 10, screw 11, lever shaft plug screw
Embodiment
In figure (1), the cylindrical body elbow of hook-type screw rod (4) is packed in the cylindrical hole of Joystick (8), the cylindrical body head is loaded onto faced washer (5), and in aperture, insert cotter pin (6), prevent that the hook-type screw rod from deviating from, support (1) is fastened on plug screw (7) with screw (10), (11) on the outer Transverse plane, hook-type screw rod (4) is loaded onto locking nut (3) and adjusting nut (2), as shown, in hook-type screw rod end grooves, load onto axle elastic wire back-up ring (9), prevent that nut from getting loose, screw rod is put into the groove of support (1), and make locking nut (3) and adjustment nut (2) lay respectively at the support both sides, only need rotation right side nut to be adjusted at idling to Joystick (8) to the arbitrary position between calibration point, when needs work long hours in this position, rotatable left side locking nut is pieced together the hook-type screw rod tightly on support, because the self-locking action of spiral can guarantee that Joystick stops for a long time in any desired location, can not be shifted because of vibration.
Claims (2)
1, a kind of Injection Pump mechanical governor fine setting operating mechanism, form by Joystick (8), support (1), hook-type screw rod (4) etc., it is characterized in that described Joystick (8) is connected with hook-type screw rod (4), described hook-type screw rod (4) can be fixed on the support (1), described support (1) is L-shaped, at one end has " U " shape groove.
2, Injection Pump mechanical governor fine setting operating mechanism according to claim 1, an end that it is characterized in that described hook-type screw rod (4) is that a cylindrical body bends to 90 °, the centre has a positive stop lug boss and head that the aperture of dress cotter pin is arranged, and the respective aperture on its cylindrical diameter and the described Joystick (8) is Spielpassung.
