Abstract
The utility model discloses a crank shaft, which relates to the field of machine equipment and aims to solve the problem that lubricant passages on a conventional crank shaft are not enough. The crank shaft comprises a crank shaft body (1), crank necks (2) and main journals (3), wherein the main journals (3) are arranged on the crank shaft body (1); the crank necks (2) are arranged between the two adjacent main journals (3); the crank shaft is characterized in that opposite lubricant passages (4) are formed on the two main journals (3) adjacent to the crank necks (2); the crank shaft has the advantages of complete shaft lubrication and cooling, simple structure and wide application range, and is convenient to use.
Description
Technical field
The utility model relates to a kind of machinery, particularly relates to the bent axle of using on a kind of machinery.
Background technique
Bent axle is the strength member of load, transferring power of withstanding shocks in the motor, and its operating conditions is abominable, and wants high speed rotating, and is therefore more and more higher to the lubricating requirement of bent axle.Present bent axle comprises bent axle body, crank throw neck and main journal, and main journal is arranged on the bent axle body, and the crank throw neck is arranged between adjacent two main journals, has only single oil leab, can not satisfy the lubricating requirement of the bent axle under the high-revolving working state of high pass filter.
The model utility content
Technical problem to be solved in the utility model provides a kind of sufficient bent axle that can well lubricate, cool off.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of bent axle, comprise bent axle body, crank throw neck and main journal, main journal is arranged on the bent axle body, the crank throw neck is arranged between adjacent two main journals, and two main journals adjacent with described crank throw neck are provided with a relative oil duct.By an oil leab in the past, change present a pair of i.e. two oil ducts into, can be better the bent axle of high speed rotating be lubricated and cools off.A plurality of crank throw necks and main journal are generally arranged on the bent axle body, manufacture and design according to actual needs.Main journal is the supporting portion of bent axle body, is bearing in by main bearing in the main bearing seat of crankcase.The number of main bearing is not only relevant with the cylinder number, also depends on the supporting means of bent axle.Generally also being connected with other parts on the crank throw neck, mainly is that the axial motion with the bent axle body is converted into straight line motion.The effect of bent axle: 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, 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.Simultaneously, bent axle is again a high speed rotating spare, therefore, requires bent axle wear-resistant and lubricated good, has enough firm and intensity, has the ability of the good load that withstands shocks.
As preferably, the angular range between the described relative oil duct is 80 °～160 °.
As preferably, described main journal all is positioned at same shaft axis.Guarantee the working efficiency of bent axle, make stressed evenly, working life will be longer like this.
As preferably, the oil duct on the described same crank throw neck is connected.Oil can better be imported like this, discharges.
A kind of crankshaft lubrication of the utility model structure, cooling are fully, and be simple in structure, easy to use, has wide range of applications.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of bent axle of the utility model.
Fig. 2 is the structural representation of the existing bent axle of the utility model.
Fig. 3 is the left view of Fig. 1.
Embodiment
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of bent axle of the utility model comprises bent axle body 1, crank throw neck 2 and main journal 3, and main journal 3 is arranged on the bent axle body 1, crank throw neck 2 is arranged between adjacent two main journals 3, and two main journals 3 adjacent with described crank throw neck 2 are provided with a relative oil duct 4.As shown in Figure 1, in the past for only being provided with an oil leab on the crank throw neck, present relatively i.e. two oil ducts that change into can be better be lubricated and cool off the bent axle of high speed rotating.A plurality of crank throw necks and main journal are generally arranged on the bent axle body, manufacture and design according to actual needs.Main journal is the supporting portion of bent axle body, is bearing in by main bearing in the main bearing seat of crankcase.The number of main bearing is not only relevant with the cylinder number, also depends on the supporting means of bent axle.Generally also being connected with other parts on the crank throw neck, mainly is that the axial motion with the bent axle body is converted into straight line motion.The effect of bent axle: 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, 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.Simultaneously, bent axle is again a high speed rotating spare, therefore, requires bent axle wear-resistant and lubricated good, has enough firm and intensity, has the ability of the good load that withstands shocks.
Angular range between the described relative oil duct 4 is 80 °～160 °.
Described main journal 3 all is positioned at same shaft axis.Guarantee the working efficiency of bent axle, make stressed evenly, working life will be longer like this.
Oil duct 4 on the described same crank throw neck 2 is connected.Oil can better be imported like this, discharges.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
