Abstract
The invention relates to a connecting rod small end bushing additionally provided with a spiral oil duct. The connecting rod small end bushing with the spiral oil duct comprises a connecting rod small end bushing (1); the side wall of the connecting rod small end bushing (1) is provided with at least two oil holes (2); the connecting rod small end bushing (1) is also provided with the spiral oil duct (3) convenient for uniformly storing the oil; the oil holes (2) are communicated with the spiral oil duct (3). The spiral oil duct (3) is in a closed structure. The connecting rod small end bushing with the spiral oil duct is helpful to establishment of a lubricant oil film. The spiral oil duct provided by the invention is in the closed structure, so that pressure oil leakage can be prevented.
Description
Technical field
The invention belongs to mechanical connecting structure, be specifically related to a kind of lining of connecting rod small end that adds spiral oil duct.
Background technique
Conventional linkage small end bushing lubricating structure is designed to: wrist pin and lining of connecting rod small end Spielpassung, connecting rod small end place processing oilhole, lining machined grooves (see figure 1).Lubricant oil is by the check-in small end bushing that splashes, and groove can be realized oil storage function, improves lubricated.This design deficiency is: when diesel engine load increases, lining of connecting rod small end oil film can not be set up, and causes wrist pin-lining of connecting rod small end wearing and tearing aggravation.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of lining of connecting rod small end that adds spiral oil duct that oil film is set up, can be avoided lining of connecting rod small end wearing and tearing that is beneficial to.
The technical solution used in the present invention: a kind of lining of connecting rod small end that adds spiral oil duct, it comprises lining of connecting rod small end 1, on its sidewall, be provided with at least two oilholes 2, be also provided with the spiral oil duct 3 of being convenient to even oil storage on lining of connecting rod small end 1, oilhole 2 communicates with spiral oil duct 3.Described spiral oil duct 3 is enclosed construction.
The present invention compared with prior art its beneficial effect is: the present invention only need to just can make oil distribute more evenly by the splash lubricant oil that enters lining of connecting rod small end of oilhole by simple processing mode, is conducive to the foundation of lubricant film; Spiral oil duct of the present invention is enclosed construction, avoids pressure draining; Cost of the present invention is low, easy to utilize.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of former lining of connecting rod small end.
Embodiment
As shown in Figure 1, a kind of lining of connecting rod small end that adds spiral oil duct, it comprises lining of connecting rod small end 1, is provided with at least two oilholes 2 on its sidewall, is also provided with the spiral oil duct 3 of being convenient to even oil storage on lining of connecting rod small end 1, oilhole 2 communicates with spiral oil duct 3.Described spiral oil duct 3 is enclosed construction.
Claims (2)
1. a lining of connecting rod small end that adds spiral oil duct, it comprises lining of connecting rod small end (1), on its sidewall, be provided with at least two oilholes (2), it is characterized in that: on lining of connecting rod small end (1), be also provided with the spiral oil duct (3) of being convenient to even oil storage, oilhole (2) communicates with spiral oil duct (3).
2. a kind of lining of connecting rod small end that adds spiral oil duct according to claim 1, is characterized in that described spiral oil duct (3) is enclosed construction.
