Abstract
Injection pump cam mounting structure mainly includes lock nut (1), packing ring (2), camshaft (3), oil pump cam (4), camshaft timing gear (5), camshaft timing gear (5), oil pump cam (4) loop through the spline and install on camshaft (3), the outside that oil pump cam (4) were gone up in camshaft (3) is installed in packing ring (2), and lock oil pump cam (4), camshaft timing gear (5) on camshaft (3) rethread lock nut (1). And constitute protruding wheel axle assembly with valve push rod (6), valve push rod (7) group, supply engine work to use. Higher pump end pressure power can be born to this patent structure under the condition that does not influence engine gear train structure to the reliability of camshaft, oil pump cam etc. Has been guaranteed.
Description
Technical field
This utility model relates to a kind of single cylinder diesel engine oil jet pump cam mounting structure, belongs to field of internal combustion engine.
Background technology
Injection pump cam is an indispensable part as electromotor operating, it it is the guarantee of engine work, along with existing engine technology level improves, for obtaining preferable fuel economy and discharge index, the pump side pressure high pressure of high-pressure oil pump of engine gradually steps up, the requirement new to the camshaft rigidity sending out machine machine.nullAt present，Domestic cam of injection pump otherwise with integrated camshaft make，Affected by the transmission wheel system structure of electromotor，The body of electromotor must strengthen，Injection pump cam and camshaft split production，Installation binding system is fixed，Affected by the transmission wheel system structure of electromotor，The diameter of camshaft is difficult to excessive，But the raising with injection pump pump end pressure，Its injection pump cam must be with less basic circle so that injection pump be supporting，But little injection pump basic circle couples with camshaft，The pump end pressure of its injection pump affects the reliability of camshaft，Cause key、Camshaft or the deformation of injection pump cam，Affect the performance of electromotor or directly cause electromotor to work，Therefore it is badly in need of a kind of new injection pump cam mounting structure，Can be in the case of not affecting engine train structure，Higher pump end pressure can be born and can guarantee that camshaft、The reliability of cam of injection pump etc..
Therefore a kind of new injection pump cam mounting structure of design, is the most necessary.
Summary of the invention
For reaching above-mentioned purpose, this utility model is by the following technical solutions, injection pump cam mounting structure, mainly include locking nut (1), packing ring (2), camshaft (3), cam of injection pump (4), camshaft timing gear (5), described camshaft timing gear (5), cam of injection pump (4) pass sequentially through spline and are installed on camshaft (3), described packing ring (2) is installed to the outside of camshaft (3) oiling pump cam (4), then cam of injection pump (4), camshaft timing gear (5) is locked on camshaft (3) by locking nut (1).
The connecting portion of described camshaft (3) is machined with external splines.
The connecting hole of described cam of injection pump (4) is machined with internal spline.
The connecting hole of described camshaft timing gear (5) is machined with internal spline.
This utility model patent, by using said structure, on the premise of not affecting engine train structure, can be born higher pump end pressure, and ensure that the reliability of camshaft, cam of injection pump.
Accompanying drawing illustrates:
Fig. 1 is injection pump cam mounting structure schematic diagram.
Detailed description of the invention
Detailed description of the invention further description to this utility model patent below in conjunction with the accompanying drawings, injection pump cam mounting structure, mainly include locking nut (1), packing ring (2), camshaft (3), cam of injection pump (4), camshaft timing gear (5), described camshaft timing gear (5), cam of injection pump (4) passes sequentially through spline and is installed on camshaft (3), described packing ring (2) is installed to the outside of camshaft (3) oiling pump cam (4), again by locking nut (1) by cam of injection pump (4), camshaft timing gear (5) is locked on camshaft (3).And form camshaft assembly with valve actuating push rod (6), valve actuating push rod (7) group, work for electromotor.
The foregoing is only preferred embodiment of the present utility model, be not used to limit the scope of the claims of the present utility model, other use the equivalence change of patent spirit of the present utility model, all should all belong to the scope of the claims of the present utility model.
