Description
Technical field
The utility model relates generally to bent axle field, particularly relate to a kind of need not the dry type bent axle of oil lubricating.
Background technique
Bent axle is indispensable parts in internal-combustion engine, existing bent axle, and its main journal, rod journal all adopt the combination of bearing shell, axle sleeve to carry out supporting, connecting, in use, each position all needs oil lubricating to work, so, manufacture, maintenance cost is higher, use is convenient not; And the main journal of this bent axle, crankweb and rod journal three are integrated casting or forging molding, and manufacture process requirement is higher.
Model utility content
The technical problems to be solved in the utility model is: the technical problem existed for prior art, provide a kind of need not oil lubricating, manufacture maintenance cost dry type bent axle low, easy to use.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of dry type bent axle, comprise main shaft, the crankweb arranged in pairs and the connecting rod axis body be connected between often pair of crankweb, described main shaft is provided with the first rolling bearing, described connecting rod axis body is made up of duplex bearing cylinder, described duplex bearing cylinder comprises cylindrical shell, back shaft and the second rolling bearing, described cylindrical shell is used for being socketed with miscellaneous part, described back shaft is arranged in cylindrical shell, and the two ends of back shaft are fixedly connected on crankweb, described second rolling bearing is installed between back shaft and cylindrical shell.
As further improvement of the utility model:
Each described duplex bearing cylinder at least has two the second rolling bearings be arranged side by side.
Two the first rolling bearings be arranged side by side at least are provided with by separated each section of main shaft of described connecting rod axis body.
Described crankweb to be socketed on main shaft and to be coordinated by key fixing.
Be arranged in two sections of main shafts at two ends, wherein one section of main shaft is provided with the land for being connected with drive unit, and another section of main shaft is provided with flywheel.
Compared with prior art, the utility model has the advantage of:
1, dry type bent axle of the present utility model, its main shaft and connecting rod axis body are all supported by rolling bearing, compare the supporting way of axial sleeve of bushing combination, without the need to lubrication when simple, work is safeguarded in the utility model manufacture, easy to use.
2, dry type bent axle of the present utility model, its crankweb is socketed on main shaft, and namely crankweb and main shaft are assembled formation again after processing separately, and compare integrally casting or forging molding, its manufacturing process is simpler.
Accompanying drawing explanation
