Abstract
The utility model discloses a crankshaft, mainly comprising a chassis and a shaft rod which are connected, wherein the chassis is divided into two ends, one end of the chassis is provided with a weight and the other end of the chassis is a crankshaft hole position; the crankshaft hole position is provided with a blind hole with an opening at the bottom; the weight and the crankshaft hole position are arranged at the two sides of the shaft rod; the shaft rod has a layered structure which is a two-layer, three-layer or four-layer stepped structure; and the weight has a sector-shaped structure. Therefore, in the crankshaft, under the premise of ensuring the strength and rigidity, the weight of an engine is reduced, the stability of the performance of the engine is improved, simultaneously, certain amount of materials and energy can be saved, the stressing balance also can be better maintained, further the stressing is more uniform, and the service life of the whole system is prolonged.
Description
Technical field
The utility model relates to a kind of parts that are in transmission connection, especially a kind of bent axle.
Background technique
In actual life, bent axle is applied to industry-by-industry widely, and as epochmaking parts of motor, it cooperates the gas pressure that will act on the piston to become the power of rotation with connecting rod, pass to the driving mechanism on chassis.Simultaneously, need it to drive distribution device and other auxiliary device, as fan, water pump, generator etc.During work, bent axle bears gas pressure, the effect of inertial force and moment of inertia, and stressed big and stressed complexity, and bear the percussion of stress alternation.Bent axle is again a high speed rotating spare, so necessarily require to have enough rigidity and intensity, has the ability of the good load that withstands shocks, and is wear-resistant and lubricated good.This shows, the working environment of bent axle is very complicated, mainly at high temperature, high pressure, work at a high speed and under the chemical corrosion condition, will inevitably be subjected to the effect of various power, yet existing bent axle chassis is the integral type block structure, be difficult to keep stressed uniform balance, destroy the chassis with producing very big non-homogeneous stress, cause bent axle to be scrapped, the strength and stiffness of axostylus axostyle are also not enough, cause fracture easily, the integral type block structure makes that the consumption of material is bigger simultaneously, waste material on the one hand not only, and make the weight of motor increase on the other hand, make its running will consume the more energy.
In sum, existing bent axle can not satisfy the requirement of motor fully, thereby influence the proper functioning of motor, cause the decline of the running quality of whole system, therefore in order to make that motor is lighter and handier, performance is more stable, must improve existing bent axle, this is a project of being badly in need of solution.
Summary of the invention
The purpose of this utility model be provide for the deficiency that solves above-mentioned technology a kind of stressed evenly, material economy has the bent axle of enough intensity and rigidity.
In order to achieve the above object, the bent axle that the utility model is designed, it mainly comprises chassis and axostylus axostyle, this chassis is connected with axostylus axostyle, and described chassis is divided into two ends, and an end is a balancing weight, the other end is the crankshaft hole position, described crankshaft hole position is provided with the blind hole of opening in the bottom, and described balancing weight and crankshaft hole position are located at the axostylus axostyle both sides, and described axostylus axostyle is branch stratiform structure.
In order to increase the intensity of axostylus axostyle, as preferably, the branch stratiform structure of described axostylus axostyle is 2 layers or 3 layers or 4 layers of step structure.
Stressedly evenly keep balance in order to make, as preferably, described balancing weight is a sector structure.
The bent axle that the utility model obtains, described chassis is divided into two ends, no longer is existing integral type block structure, described balancing weight is designed to sector structure simultaneously, has so both saved material, reaches a conclusion through a large amount of experiments, can also keep stress balance better, make stressed more even; And described axostylus axostyle is designed to step structure, can increase the strength and stiffness of axostylus axostyle, increases the transmission performance of motor, improves its overall performance.Thereby described bent axle can alleviate the weight of motor under the prerequisite of proof strength and rigidity, increases the stability of engine performance, can also save a certain amount of material and the energy.
Description of drawings
Fig. 1 is embodiment 1 a structural representation;
Fig. 2 is a worm's eye view of the present utility model;
Fig. 3 is a plan view of the present utility model;
Fig. 4 is embodiment 2 a structural representation;
Among the figure: axostylus axostyle 1, balancing weight 2, crankshaft hole position 3, blind hole 4 is divided stratiform structure 5.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As Fig. 1, Fig. 2 and shown in Figure 3, the described bent axle of present embodiment, it mainly comprises chassis and axostylus axostyle, and this chassis is connected with axostylus axostyle, and described chassis is divided into two ends, one end is a balancing weight, the other end is the crankshaft hole position, and described crankshaft hole position is provided with the blind hole of opening in the bottom, and described balancing weight and crankshaft hole position are located at the axostylus axostyle both sides, described axostylus axostyle is branch stratiform structure, this minute the stratiform structure can be 2 layers of step structure; Described balancing weight is a sector structure.Thereby under the prerequisite of proof strength and rigidity, alleviate the weight of motor, increase the stability of engine performance, improve the running quality of whole system, can also save a certain amount of material and the energy.
As shown in Figure 4, the described bent axle of present embodiment, the affiliated branch stratiform structures different with embodiment 1 can be 3 layers of step structure, thereby axostylus axostyle long strength of crankshaft and rigidity are protected, make the stability that increases engine performance, improve the running quality of whole system.
