Description
Technical field
The utility model belongs to technical field of transmission machinery, specifically, relates to a kind of taper crank.
Background technique
Crank is a kind of transmission part, is applied in engine power system, is the vitals of engine operational cycle.In crank working procedure, need to-and-fro motion, assist motor to complete expansion stroke, in this process, crank ceaselessly rotates, and the piston being mated work ceaselessly moves up and down, and completes the conversion of mechanical energy to kinetic energy.Can produce friction between the parts be mated in the movement process of crank, the movement process due to crank is a lasting long process, and long friction very easily causes the damage of crank part.Once the friction resistant effect of crank is bad, structure is not stable, will cause the damage of crank, will have a strong impact on the working life of crank.
Model utility content
The purpose of this utility model is to provide a kind of long service life, the taper crank that abrasion resistant effect is good.
The technical solution of the utility model is: motor taper crank, comprises crankshaft and counterweight, and described crankshaft is segmentation shape structure, comprises the pillow block be connected with counterweight, the frustum be connected with pillow block and pillow block before being connected with frustum; Described pillow block and front pillow block are cylindrical body, and described frustum is circular cone; The mesa diameter of pillow block, frustum and front pillow block reduces successively, and the length of the stage body of pillow block, frustum and front pillow block also reduces successively; Counterweight is disc-shaped structure, and the side of disk is crankshaft installation side, and crankshaft is arranged on the center of this side discs, and the opposite side of disk is linkage rod installation side, is provided with linkage rod mounting hole, and linkage rod mounting hole is arranged on the position of non-disc centre; In the card of crankshaft installation side disk, be symmetry center with crankshaft, be symmetrically arranged with axle side oil groove; In the disk card of linkage rod installation side, the position corresponding with axle side oil groove is provided with bar side oil groove.
Preferably: the joint of pillow block and frustum seamlessly transits, namely the mesa diameter that connects of frustum and pillow block is identical.
Preferably: front pillow block is also provided with oil groove, oil groove is arranged in front pillow block cylindrical sidewall, is the rectangular configuration caved inward along cylindrical sidewall.
The beneficial effects of the utility model are:
(1) crankshaft is designed to segmentation shape structure, relatively single columned crankshaft, can crankshaft stressed in balanced rotation process, make crank structure more stable.
(2) counterweight one side or two-sided oil groove is set, during work, the oil that oil groove stores can flow to the various piece of crank along with the rotation of crank, lubricates whole parts, reduces the damage rubbing and cause crank.
(3) on front pillow block, be also provided with oil groove, before in work, pillow block is the part be connected with miscellaneous part, is also the part of easily damage, arranges oil groove here, can strengthen the lubrication effect to front pillow block, avoid the damage to crank.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the left TV structure schematic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Motor taper crank, comprises crankshaft and counterweight 1, and described crankshaft is segmentation shape structure, comprises the pillow block 2 be connected with counterweight 1, the frustum 3 be connected with pillow block 2 and pillow block 4 before being connected with frustum 3; Described pillow block 2 and front pillow block 4 are cylindrical body, and described frustum 3 is circular cone; The mesa diameter of pillow block 2, frustum 3 and front pillow block 4 reduces successively, and the joint of pillow block 2 and frustum 3 seamlessly transits, and namely frustum 3 is identical with the mesa diameter that pillow block 2 connects.
Counterweight 1 is disc-shaped structure, and the side of disk is crankshaft installation side, and crankshaft is arranged on the center of this side discs, and the opposite side of disk is linkage rod installation side, is provided with linkage rod mounting hole 6, and linkage rod mounting hole 6 is arranged on the position of non-disc centre; In the card of crankshaft installation side disk, be symmetry center with crankshaft, be symmetrically arranged with axle side oil groove 5; In the disk card of linkage rod installation side, the position corresponding with axle side oil groove is provided with bar side oil groove.
Front pillow block 4 is also provided with oil groove, and oil groove is arranged in front pillow block cylindrical sidewall, is the rectangular configuration caved inward along cylindrical sidewall.
A gear unit is made up of two cranks.Axle side oil groove, bar side oil groove and front pillow block oil groove all configure certain lubricant oil, front pillow block be thread-like structure foremost, during use, be connected with miscellaneous part by screw thread, linkage rod is arranged between the linkage rod mounting hole of two cranks, and piston sleeve is contained in linkage rod, moves up and down.Lubricant oil in movement process in oil groove, with motion flow each position to crank, plays lubrication.
Claims (3)
