Abstract
The utility model relates to a kind of connecting rob bushing for Large-power High-Speed diesel engine, and its object is for providing a kind of rational in infrastructure, connecting rob bushing that longer service life, bearing capacity are stronger.A kind of connecting rob bushing for Large-power High-Speed diesel engine of the utility model, comprises the oil groove in bush body, bush body, and described bush body both sides end face is curved, and the width of described oil tank inlet is the half of bush body two side ends face length degree.Take such structure that more lubricant oil can be made better to enter oil groove, reduce the friction between connecting rob bushing and wrist pin, effectively extend the working life of connecting rob bushing.
Description
Technical field
The utility model belongs to mechanical field, especially a kind of connecting rob bushing for Large-power High-Speed diesel engine.
Background technique
Connecting rob bushing is the important connected element of connecting rod small end and wrist pin.It is actually the bearing bush of small end bearing, usually matches with the bearing saddle bore of connecting rod small end in the mode of interference.The alternating action of the pressure of explosion of link assembly inertial force and piston transmission is subject in real work.In concrete use, except the selection to material, the lubricating status of connecting rob bushing also determines its working life and effect.Connecting rob bushing shape common is at present drum type, and the lining of this form is due to easily manufactured, rational in infrastructure, is therefore a kind of connecting rob bushing shape the most generally used.Diesel engine unit operationally, for keeping the lubrication between lining and wrist pin, need externally to interior injection lubricant oil, lubricant oil splashes along with the motion of connecting rod in confined space, trickle down the end face in lining both sides, enter the gap inside bush body and between wrist pin along oil tank inlet, thus play and lubricate and the effect reduced wear.
But drum type connecting rob bushing two end faces are straight line, and connecting rob bushing and wrist pin spin, therefore the end face of connecting rob bushing and wrist pin end face are a burnishing surface, and lubricant oil is trickled down and is not easy to collect on this burnishing surface, is also difficult to enter oil groove.And oil tank inlet width all is at present consistent with oil groove width, is also unfavorable for that lubricant oil is better more and enters oil groove.
Model utility content
For overcoming above-mentioned technological deficiency, the utility model provides the connecting rob bushing for Large-power High-Speed diesel engine that a kind of moulding is simple, rational in infrastructure, bearing capacity is stronger.
A kind of connecting rob bushing for Large-power High-Speed diesel engine of the utility model, comprise the oil groove in bush body, bush body, it is characterized in that: described bush body both sides end face is curved, the width of described oil tank inlet is the half of bush body two side ends face length degree.
After taking such structure, the length of connecting rob bushing end face increases, thus the area collecting lubricant oil increases, arcuate structure itself is also conducive to collecting of lubricant oil, the width of oil tank inlet increases to the half of bearing shell end face length simultaneously, therefore can ensure that more lubricant oil better enters oil groove, effectively reduces the friction between lining and wrist pin, connecting rob bushing through transformation is tested under comparable operating conditions, and lining can not extend 1200-1600 hour not etc. working life.

Embodiment
Shown in composition graphs 1, Fig. 2 and Fig. 3, a kind of connecting rob bushing for Large-power High-Speed diesel engine of the utility model, comprise the oil groove 2 in bush body 1, bush body 1, described bush body both sides end face 3 is curved, and the width of described oil tank inlet 4 is the half of bush body both sides end face 3 length.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
