Abstract
The utility model discloses a speed control lever for a single cylinder diesel engine, comprising a lever body, a feeler lever and a fork lever, wherein, a central shaft hole is arranged on the lever body; a contact member with a convex curved surface is fixed to the end part of the feeler lever; the contact member is contacted with a plane bearing for regulating speed of a diesel engine; the abrasive resistance of contact member is good, so that the stable and reliable performance for regulating the speed is ensured. In addition, the utility model has the advantages of high sensitivity and easy production.
Description
The utility model relates to a kind of single cylinder diesel speed regulator, the structure of especially relevant governor lever.
The governor lever of the single cylinder diesel of Xiao Shouing generally adopts the malleable cast iron manufacturing in the market, and this malleable cast iron metallographic structure is ferrite and temper carbon, and hardness is not more than HB150.In diesel engine when work,, the active force of the variation that plane bearing applies will be born in the feeler lever end of governor lever, and and plane bearing between produce the pressure inequality slip or rolling friction, this just requires the feeler lever end to have certain rigidity, it is good to make it wear resistance.General way is governor lever to be carried out straight-line hardening handle now, in the hope of improving feeler lever end hardness, yet because the quenching technical of malleable cast iron material is immature, thereby the hardness of feeler lever end can not be stablized, during work, tend to occur feeler lever end premature wear, make the diesel engine speed regulation performance unstable thereupon, influence the functional reliability and the working life of diesel engine.
The purpose of this utility model is to provide a kind of feeler lever end wear resistance good, the single cylinder diesel governor lever that speed adjusting performance is reliable and stable.
In order to achieve the above object, the utility model by the following technical solutions: a kind of single cylinder diesel governor lever, comprise shaft, feeler lever and fork arm, have central axis hole on the shaft, the feeler lever end fixedly be equipped with the band convex surface contact.
In order to achieve the above object better, and improve speed governing sensitivity, the feeler lever end is contacted with the plane bearing holding point, and the shape of contact is preferably made one by the cylindrical body of the hemisphere on top and bottom and is formed, and the feeler lever end has the mounting hole of packing into for cylindrical body.
In order to reach above-mentioned same purpose, and whole governor lever is easily manufactured, and contact also can be spheroid, and the feeler lever end has corresponding pit, spheroid and pit attaching.
In order to reach above-mentioned same purpose, contact also can be hemisphere, and the feeler lever end has flat pit or flat bottomed recess, and hemisphere is installed on flat pit or the flat bottomed recess.
Owing to fixedly mounted the contact of band convex surface in the feeler lever end of governor lever, just can allow the working position convex surface and the plane bearing of contact keep in touch, the phase mutual friction, and this contact can make and adopt easy quenching or high-abrasive material to make separately, wear resistance is good during use, thereby guaranteed the reliable and stable of speed adjusting performance, simultaneously owing to cancelled the quenching technical of malleable cast iron, it is more convenient that governor lever is made, contact contacts with plane bearing point in addition, can improve diesel engine speed regulation sensitivity.
The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.
Fig. 1 is first embodiment's of single cylinder diesel governor lever of the present utility model structural representation and a working condition reference drawing thereof.
Fig. 2 is a plan view embodiment illustrated in fig. 1.
Fig. 3 is second embodiment's feeler lever cross-sectional end view of the present utility model.
Fig. 4 is the 3rd embodiment's feeler lever cross-sectional end view of the present utility model.
Single cylinder diesel governor lever as shown in Figure 1, 2 comprises shaft (1), two feeler levers (2) and fork arm (3), has central axis hole (4) on the shaft (1).Fork arm (3) is used for controlling the high-pressure fuel pump of diesel engine plunger so that the control fuel delivery, feeler lever (2) is subjected to the active force of the variation that plane bearing (13) applied, and and plane bearing (13) between produce the pressure inequality slip or rolling friction, whole governor lever can be rotated around the medial axis (12) of central axis hole (4).The contact (5) of band hemisphere face (6) is housed in the end of feeler lever (2).Because feeler lever (2) is to utilize the convex surface of contact (5) as the working position, thereby hemisphere face (6) also can wait convex surface alternative with cylndrical surface or dolioform.Contact (5) is to make one by the hemisphere on top and the cylindrical body of bottom (7) to form.Contact (5) adopts easy quenched materials to make, and quenching back hardness can be in HRC40～45.Contact (5) also can adopt high-abrasive material to make.The end of feeler lever (2) has the mounting hole (8) of packing into for cylindrical body (7), cylindrical body (7) adopts interference fit with mounting hole (8), or adopt Spielpassung and cement with binder, also can adopt and go up screw thread in the processing of the bottom of cylindrical body (7) and connect in modes such as nut checks again.
As shown in Figure 3, the contact (5) of feeler lever (2) the end load among second embodiment of the utility model is a spheroid, and feeler lever (2) end has corresponding pit (9), and spheroid and pit (9) adopt binder bonding.Pit (9) then can be pressed into the interference of spheroid Lower Half if change circular blind hole into.
As shown in Figure 4, the contact (5) of feeler lever (2) the end load among the 3rd embodiment of the utility model is a hemisphere, and feeler lever (2) end has flat pit or flat bottomed recess (10), and hemisphere is riveted or is bonded on flat pit or the flat bottomed recess (10).
Contact (5) among second and third embodiment of the present utility model also can correspondingly change cylindrical body and semicylinder into, but the axis of contact (5) should with central axis (12) keeping parallelism of central axis hole (4).
Governor lever in the foregoing description is the governor lever of two feeler levers, and the technical solution of the utility model is equally applicable to the governor lever of single feeler lever.
During governor lever work, the contact (5) of feeler lever (2) end load keeps sliding and rolling friction with plane bearing (13), and under the promotion of centrifugal force that the flyball rotation produces in speed control system and speed governing sliding plate axial force, make feeler lever (2) (12) rotation by plane bearing (13) around the medial axis, make fork arm (3) drive the high pressure oil pump plunger action, thereby increase or reduce fuel delivery, regulate the rotating speed of diesel engine under various operating modes, guaranteed the power output of diesel engine under various load conditions.
