Description
Technical field
The utility model relates to valve stem field, particularly relates to a kind of valve stem offering lubricant oil oil strain groove.
Background technique
Valve stem is that a kind of thrust by push rod passes to rocking arm, drives the device of valve opening.The upper and lower termination of push rod is through heat treatment and rubbing down, and to improve wear resistance, shaft has solid and hollow two kinds.One end of push rod and cam contact, the other end and valve contacts, its effect is that the thrust of cam is passed to valve.But traditional valve stem does not possess the function self adding lubricant oil, long-term related system work is abnormal, causes component lubrication not enough, and the easy generating portion of valve stem is damaged.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of valve stem offering lubricant oil oil strain groove, top cap can be arranged to lubricant oil stored type, when valve stem works, energy constantly removal of lubricant, increases the lubricity of valve stem, extends working life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of valve stem offering lubricant oil oil strain groove, comprise push rod body, described push rod body one end is provided with thimble, the described push rod body the other end establishes crown cap, described top cap is an inner cap body for cavity body, cap front end, described top is horizontal front cover, cap rear end, described top is arc front cover, described top cap rear end arc front cover central authorities offer oil outlet, described push rod body offers oil-discharge trough, described oil-discharge trough one end is connected on described oil outlet, it is outside that the described oil-discharge trough the other end derives described thimble.
In the utility model preferred embodiment, cap one end, described top is provided with loading channel, and described loading channel protrudes from the cap end face of described top, and described loading channel is provided with one and revolves capping.
In the utility model preferred embodiment, be also provided with a ball body in the cap of described top, when described push rod body is vertically placed, described ball body is butted on described oil outlet.
In the utility model preferred embodiment, described oil-discharge trough is for embedding the intrinsic oil exit pipe of described push rod, and described oil-discharge trough one end connecting sealed connects described oil outlet, and the described oil-discharge trough the other end is horizontally disposed with and extends to described thimble outside.
The beneficial effects of the utility model are: top cap can be arranged to lubricant oil stored type by the utility model, and when valve stem works, energy constantly removal of lubricant, increases the lubricity of valve stem, extend working life.
