Description
Technical field
The utility model relates to bent axle field, is specifically related to a kind of detachable bent axle.
Technical background
Bent axle is widely used on the equipment such as internal-combustion engine, air compressor, is the critical component on internal-combustion engine, air compressor, requires high, and consumption is large, and existing bent axle is integrated type mostly, and difficulty of processing is large, and waste of material is serious.
Model utility content
The purpose of this utility model is to provide a kind of detachable bent axle, have detachable, process easy, save the advantages such as material.
The utility model adopts following technological scheme:
A kind of detachable bent axle, is made up of the first concentric shafts, eccentric shaft, the second concentric shafts, oil hole, fixing pin breach, conical bore, counterweight hole, fixing pin, disk.
Described first concentric shafts is connected a disk respectively with the second concentric shafts, installs an eccentric shaft between two disks.
Described first concentric shafts and the second concentric shafts be also provided with conical bore and fixing pin breach towards outer end.
Described bent axle is provided with oil hole.
Described disk is provided with counterweight hole.
Preferably, the two ends of described eccentric shaft are inserted in disk, and are fixed by fixing pin outstanding on eccentric shaft and disk.
Preferably, the diameter of described eccentric shaft is greater than the part inserting disk, and the part had more is close to the surface of disk.
Preferably, described disk is provided with two breach.
Preferably, there is certain angle in described oil hole and bent axle face.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Fig. 2 is plan view of the present utility model.
Wherein: 1. the first concentric shafts, 2. eccentric shaft, 3. the second concentric shafts, 4. oil hole, 5. fixing pin breach, 6. conical bore, 7. counterweight hole, 8. fixing pin, 9. disk.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further.
As shown in Figure 1 and Figure 2, a kind of detachable bent axle, is made up of the first concentric shafts 1, eccentric shaft 2, second concentric shafts 3, oil hole 4, fixing pin breach 5, conical bore 6, counterweight hole 7, fixing pin 8, disk 9 the utility model.
Described first concentric shafts 1 is connected a disk 9 respectively with the second concentric shafts 3, disk 9 is provided with two breach, the use of material can be reduced, that also can reduce disk 9 occupies space, assign an eccentric shaft 2 between two disks 9, eccentric shaft 2 is interfixed by fixing pin 8 outstanding on axle and two disks 9, and the diameter of eccentric shaft 2 is greater than the part inserting disk 9, the part had more is close to the surface of disk 9, can prevent eccentric shaft 2 from axially sliding in disk 9.
Described first concentric shafts 1 and the second concentric shafts 3 be also provided with conical bore 6 and fixing pin breach 5 towards outer end.
Be provided with oil hole 4 around described bent axle, and oil hole 4 and bent axle face there is certain angle, lubricant oil can be deposited as in oil hole 4, play the effect of lubrication bent axle, extend the working life of bent axle.
Described disk is provided with counterweight hole 7, the initial unbalance after Crankshaft Machining can be reduced, thus reach the last balance quality improving bent axle.
Described bent axle is connected by demountable mode with eccentric shaft 2 by the first concentric shafts 1, second concentric shafts 3, disk 9, and each part can separate machined, have detachable, process easy, save the advantages such as material.
