Description
Technical field
The utility model belongs to technical field of transmission machinery, specifically, relates to a kind of 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 straight shape crank that abrasion resistant effect is good.
The technical solution of the utility model is: crank, comprise crankshaft and counterweight, crankshaft is segmentation shape structure, comprise the pillow block be connected with counterweight, with extended outward middle pillow block and front pillow block by pillow block, pillow block, middle pillow block and front pillow block are cylindrical body, and the diameter of the cylinder section of pillow block, middle pillow block and front pillow block reduces gradually, and cylinder length also reduces gradually; Counterweight is disc-shaped structure, the side of disk is crankshaft installation side, crankshaft is arranged on the center of this side discs, the opposite side of disk is linkage rod installation side, be provided with linkage rod mounting hole, be that disk is divided into two symmetrical semicircles by standard with circle disk center, linkage rod mounting hole is arranged on a semi circular surface, and the thickness arranging the semi circular surface of linkage rod mounting hole side is less than the thickness of second half disc; In the card of linkage rod installation side, the bore edges around linkage rod mounting hole is provided with a circle oil groove; In the card of crankshaft installation side disk, be symmetry center with crankshaft, be symmetrically arranged with axle side oil groove.
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) in counterweight disc face, arrange oil groove, 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) around linkage rod mounting hole, oil groove is set at the opening of card, the lubrication to linkage rod can be strengthened.
(4) 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 right TV structure schematic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Crank, comprise crankshaft and counterweight 1, crankshaft is segmentation shape structure, comprise the pillow block 2 be connected with counterweight 1, with extended outward middle pillow block 3 and front pillow block 4 by pillow block, pillow block 2, middle pillow block 3 and front pillow block 4 are cylindrical body, and the diameter of the cylinder section of pillow block 2, middle pillow block 3 and front pillow block 4 reduces gradually, and cylinder length also reduces gradually; Counterweight 1 is disc-shaped structure, the side of disk is crankshaft installation side, crankshaft is arranged on the center of this side discs, the opposite side of disk is linkage rod installation side, be provided with linkage rod mounting hole 5, be that disk is divided into two symmetrical semicircles by standard with circle disk center, linkage rod mounting hole 5 is arranged on a semi circular surface, and the thickness arranging the semi circular surface of linkage rod mounting hole side is less than the thickness of second half disc; In the card of linkage rod installation side, the bore edges around linkage rod mounting hole is provided with a circle oil groove 7; In the card of crankshaft installation side disk, be symmetry center with crankshaft, be symmetrically arranged with axle side oil groove 6.
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.The oil groove 7 and front pillow block oil groove at axle side oil groove, linkage rod mounting hole place all configure certain lubricant oil, front pillow block 4 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, 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.
