Specific embodiment
Specific embodiment of the present utility model is made into one by the description to optimum embodiment below against attached drawing
Step detailed description.
The utility model specific embodiment are as follows: as shown in Figure 1 and Figure 2, a kind of auxiliary machine of camshaft steady running
The rear end of camshaft 1, including bar shaped elastic slice 2, one end of bar shaped elastic slice 2 and the axle journal Elastic Contact of camshaft 1 is arranged in structure,
The other end of bar shaped elastic slice 2 is fixed on engine cylinder body 3.
Specifically, when the abrasion loss of bar shaped elastic slice 2 is excessive contactless with 1 axle journal of camshaft, in order to reduce to bar shaped bullet
The replacement number of piece 2 facilitates adjusting, and the adjustment means for adjusting itself and the journal contact of camshaft 1 are additionally provided on bar shaped elastic slice 2
4。
Further, this adjustment means 4 includes with flowering structure, and a kind of structure is, as shown in figure 3, adjustment means 4 include setting
The regulating tank 41 in 2 end of bar shaped elastic slice is set, the connection bolt 42 fixed with engine cylinder body 3 is installed in regulating tank 41.Tool
Body, the bolt head of connection bolt 42 covers regulating tank 41, it is therefore prevented that connection bolt 42 falls off in regulating tank 41, connects spiral shell
The threaded shank and 41 clearance fit of regulating tank of bolt 42, adjustment connects position of the bolt 42 in regulating tank 41 for convenience.Specifically
Principles of Regulation be, can be by manually to camshaft 1 when the abrasion loss of bar shaped elastic slice 2 is excessive contactless with 1 axle journal of camshaft
Bar shaped elastic slice 2 is moved in direction, makes bar shaped elastic slice 2 and 1 journal contact of camshaft, then adjusts connection bolt 42 in regulating tank 41
Position it is fixed.
Another structure is, as shown in figure 4, adjustment means 4 include extension spring 43, one end connection strap of extension spring 43
Shape elastic slice 2, the other end of extension spring 43 are connected to 3 inside of engine cylinder body, and extension spring 43 plays automatic adjustment bar shaped
The effect of 2 position of elastic slice.In order to keep the auto-reset function of extension spring 43 more preferable, extension spring 43, bar shaped elastic slice 2 and start
Triangle is surrounded between machine cylinder body 3, the center for making extension spring 43 be connected to bar shaped elastic slice 2 is biased at the position of camshaft 1.Tool
The Principles of Regulation of body are that extension spring 43 is in tensional state, and 1 axis of bar shaped elastic slice 2 and camshaft in normal state
Neck contact, pulling force of the extension spring 43 by bar shaped elastic slice 2, if bar shaped elastic slice 2 generates big abrasion loss, moment extension spring 43
No longer by the pulling force of bar shaped elastic slice 2, in order to maintain the balance of structure, extension spring 43 hauls bar shaped elastic slice 2 and moves downward, and makes item
1 journal contact of shape elastic slice 2 and camshaft, reaches equilibrium state, plays the role of automatically reseting.
Specifically, one end of bar shaped elastic slice 2 is set as the arc contact-segment 21 cooperated with the journal contact of camshaft 1, makes
The journal contact of bar shaped elastic slice 2 and camshaft 1 is smoother, reduces abrasion；Optimally, arc contact-segment 21 and camshaft 1
The circular arc portion of journal contact is less than the 1/4 of 1 axle journal circumference circle of camshaft, when arc contact-segment 21 generates big abrasion,
The position for being conveniently adjusted bar shaped elastic slice 2 does not generate interference with the axle journal of camshaft 1, further reduces the mill during adjustment
Damage；Optimally, the inside of arc contact-segment 21 is provided with the oil storage tank 22 of storage lubricating oil, and oil storage tank 22 can be set to curved
Strip groove is covered on the inside of arc contact-segment 21, convenient for storing the mist of oil of camshaft motion generation in time, makes bar shaped elastic slice 2
Lubrication between 1 axle journal of camshaft is more abundant, reduces the abrasion between 1 axle journal of bar shaped elastic slice 2 and camshaft, further prolongs
The service life of bar shaped elastic slice 2 is grown.
To sum up, the utility model structure it is simple, it is easy to adjust flexibly, it is long service life, at low cost, ensure that camshaft exists
Rear and front end stress balance in operation process reduces warpage of the camshaft in running at high speed, and increases camshaft operating
Stationarity reduces the partial wear of camshaft-bearing cap, axle journal, enhances the reliability of engine.
The above, some principles of the utility model that only explains through diagrams, this specification are not intended to this is practical
It is novel to be confined in the shown specific structure and the scope of application, thus it is all it is all may be utilized accordingly modify and wait
Jljl belongs to the applied the scope of the patents of the utility model.
