Compared with prior art, the utility model has following beneficial effect: this motor rockshaft is divided into two-part; pitman arm shaft body portion and blocking portion; pitman arm shaft body is hollow structure; this hollow structure is not existing grease channel; hollow structure both can as the passage of lubricant oil; can play again and fall heavy effect; blocking can be arranged on the two ends of pitman arm shaft body by interference fit; ensure the sealability of lubricant oil, the oil leab of whole pitman arm shaft is arranged simple, the installation registration of pitman arm shaft; lightweight, easy to process.
Accompanying drawing explanation
Fig. 1 is the plan view according to motor rockshaft of the present utility model;
Fig. 2 is the sectional view according to motor rockshaft of the present utility model;
Fig. 3 is the left view according to motor rockshaft of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 1 to Figure 3, according to a kind of motor rockshaft of the utility model embodiment, this motor rockshaft is used for fixing and is arranged on rocker shaft bed, this motor rockshaft comprises pitman arm shaft body 1 and two blockings 2, wherein pitman arm shaft body 1 is hollow structure, the two ends of this pitman arm shaft body 1 have construction section, construction section is provided with radial oil inlet hole 11, the intermediate portion of pitman arm shaft body 1 is rotating shaft section, rotating shaft section is provided with radial oil outlet 12, oil inlet hole 11 is communicated with the hollow structure of oil outlet 12 by pitman arm shaft body 1, two blockings 2 are filled in the both ends open of pitman arm shaft body 1 respectively and then are sealed by the hollow structure of pitman arm shaft body 1.
In such scheme, this motor rockshaft is divided into two-part; pitman arm shaft body portion and blocking portion; pitman arm shaft body 1 is hollow structure; this hollow structure is not existing grease channel; blocking 2 can be arranged on the two ends of pitman arm shaft body 1 by interference fit, ensures the sealability of lubricant oil.Like this, lubricant oil enters hollow structure by oil inlet hole 11, then enters rocking arm by oil outlet 12, lubricates rocking arm, and oil leab is arranged simple, easy to process.In this programme, the diameter of hollow structure is more much larger than the diameter of oil inlet hole 11 and oil outlet 12, both as the passage of lubricant oil, can play again and fall heavy effect.
