Abstract
The utility model belongs to mechanical field, and the purpose of this utility model is to provide kind of a Novel diesel cam shaft structure, can bear pump end pressure higher and can guarantee that the reliability of camshaft, cam of injection pump on the premise of engine train structure is not influenceed.Its design technology project is：Camshaft includes cam of injection pump, camshaft timing gear supporting shaft portion, admission cam, exhaust side cam cap portion, cam of injection pump, camshaft are made of one, the diameter that cam of injection pump, camshaft timing gear support shaft, camshaft install bearing supporting shaft portion is sequentially reduced, and camshaft timing gear, bearing must be from camshaft A ends（Body flywheel side）Camshaft is mounted in successively, and camshaft supporting end is supported by gear cap lid, body, and axially position is completed by necessary positioning method, completes cam s function.
Description
Technical field
The utility model is related to a kind of cam shaft for diesel engine architecture invention patent structure, belongs to mechanical field.
Background technology
Camshaft is an indispensable part as engine operating, is the guarantee of engine work, to obtain
Preferable fuel economy and discharge index are obtained, with application of the electric control pump on small diesel engine, the pump end of oil pump for engine
Pressure high pressure is gradually stepped up, the new requirement of the camshaft rigidity to sending out machine machine.At present, the jerk pump of domestic single cylinder large-diameter
Cam is made with integrated camshaft, is influenceed by the transmission wheel system structure of engine, and camshaft oil pump end is directly installed on body,
Its bearing-surface is wider, causes diesel-engine body wide, and specific mass parameter is larger, and assemble sequence is camshaft timing gear from camshaft
A ends are assemblied on camshaft by its endoporus, and take appropriate positioning method；The cam of injection pump of small diesel engine with
Camshaft split production, camshaft timing gear is assemblied on camshaft from camshaft A ends by its endoporus, cam of injection pump also from
Camshaft A ends are assemblied on camshaft, and the other manner such as installation key is fixed, and camshaft oil pump end is arranged on body by bearing
On, its bearing-surface is narrower, while the diesel-engine body transmission wheel system structure by engine wide is influenceed, the diameter of camshaft was difficult
Greatly, but with the raising of injection pump pump end pressure, the spray that its injection pump cam must be so that injection pump be supporting but small with less basic circle
Oil pump basic circle couples with camshaft, and the pump end pressure of its injection pump influences the reliability of camshaft, causes key, camshaft or oil spout
The deformation of pump cam, influences the performance of engine or directly causes the engine cannot to work, therefore a kind of new small-sized bavin of urgent need
Oil machine camshaft structure patent of invention structure, can bear pump end higher in the case where engine train structure is not influenceed
Pressure simultaneously can guarantee that the reliability of camshaft, cam of injection pump etc..
Therefore a kind of cam shaft for diesel engine architecture invention patent structure is designed, is very necessary.
The content of the invention
The purpose of this utility model is to provide kind of a Novel diesel cam shaft structure, can not influence engine train structure
On the premise of, cam of injection pump, camshaft are made of one, pump end pressure higher can be born and can guarantee that camshaft, oil pump are convex
The reliability of wheel.
Technical scheme is：Camshaft（2）Including cam of injection pump（3）, camshaft timing gear supporting shaft portion（5）, air inlet
Cam（8）, exhaust cam（9）Part, camshaft timing gear（5）, bearing（6）Camshaft is mounted in successively from camshaft B ends
（2）, camshaft supporting end passes through gear cap lid（1）, body（2）Supporting, axially position is completed by necessary positioning method, complete
Into cam s function.
Brief description of the drawings
Fig. 1 cam shaft for diesel engine structural representations.
The present invention is a kind of new diesel engine cam axle construction, by cam of injection pump, camshaft on small-sized single cylinder diesel engine
It is made of one, can bears pump end pressure higher and can guarantee that convex in the case where engine train structure is not influenceed
The reliability of wheel shaft, cam of injection pump etc..
Specific embodiment
In accompanying drawing 1, camshaft（2）Including cam of injection pump（3）, camshaft timing gear supporting shaft portion（5）, admission cam
（8）, exhaust cam（9）Part, camshaft timing gear（4）, bearing（6）Camshaft must be successively mounted in from camshaft B ends（2）,
Camshaft supporting end passes through gear cap lid（1）, body（2）Supporting, completes axially position, for starting by necessary positioning method
Machine work is used, and completes cam s function.
The present invention is can be in the case where engine train structure not be influenceed, by cam of injection pump, camshaft timing gear branch
Hold axle, the diameter of camshaft installation bearing supporting shaft portion to be sequentially reduced, cam of injection pump, camshaft are made of one, and are assembled into convex
Wheel shaft timing gears, bearing are mounted on camshaft successively from camshaft B ends, make it to bear pump end pressure higher and can guarantee that
The reliability of camshaft, cam of injection pump etc..
