Abstract
The utility model discloses a combined crankshaft for an engine. The combined crankshaft comprises a crankshaft body connecting rod, a front main journal, a rear main journal, a main journal, a plurality of connecting rod journals and crankshaft arms, wherein the main journal is processed in the center of the crankshaft body connecting rod; the front main journal is processed at the left end of the crankshaft body connecting rod; the rear main journal is processed on the right side of the crankshaft body connecting rod; five connecting rod journals are processed on the surface of the main journal; and crankshaft arms are arranged among the connecting rod journals. With the adoption of the manner, according to the combined crankshaft for the engine, the matching installation accuracy is high, and up-and-down motion of bearable connecting rods is changed into circulating motion.
Description
Technical field
The utility model relates to mechanical Component field, particularly relates to the vuilt-up crankshaft that a kind of motor is used.
Background technique
In recent years, the domestic forging equipment of having introduced a collection of advanced person, but because quantity is few, technology of die manufacturing and some other facility do not catch up with in addition, make a part of sophisticated equipment not bring into play due effect.On the whole, need the outmoded common forging equipment of transformation and renewal many, simultaneously, the technology and equipment that falls behind is dominate still, and advanced technology is used to some extent but be also not general.Bent axle is important parts on the motor, and the rotation of bent axle is the power source of motor, also is the driving source of whole mechanical system.
The model utility content
The technical problem that the utility model mainly solves provides the vuilt-up crankshaft that a kind of motor is used, and cooperates installation precision high, can accept moving up and down of connecting rod and become shuttling movement.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: the vuilt-up crankshaft that provides a kind of motor to use, comprise: bent axle main body connecting rod, forward spindle neck, rear main journal, main journal, a plurality of rod journal and crank arm, described bent axle main body connecting rod center is processed with main journal, the left end of described bent axle main body connecting rod is processed with the forward spindle neck, the right of described bent axle main body connecting rod is processed with rear main journal, the surface Machining of described main journal has five rod journals, is provided with crank arm between the described rod journal.
In preferred embodiment of the utility model, the front end of described crank arm is provided with the vibration damper joint.
In preferred embodiment of the utility model, the rear end of described crank arm is provided with the oil sealing piece.
In preferred embodiment of the utility model, in the described rod journal equilibrium block is installed.
The beneficial effects of the utility model are: the vuilt-up crankshaft that a kind of motor of the utility model is used, and cooperate installation precision high, can accept moving up and down of connecting rod and become shuttling movement.
Description of drawings
Fig. 1 is the structural representation of vuilt-up crankshaft one preferred embodiment used of a kind of motor of the utility model;
The mark of each parts is as follows in the accompanying drawing: 1, forward spindle neck, 2, bent axle main body connecting rod, 3, crank arm, 4, equilibrium block, 5, the vibration damper joint, 6, the oil sealing piece, 7, rod journal, 8, rear main journal, 9, main journal.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, the vuilt-up crankshaft that a kind of motor is used, comprise: bent axle main body connecting rod 2, forward spindle neck 1, rear main journal 8, main journal 9, a plurality of rod journal 7 and crank arm 3, described bent axle main body connecting rod 2 centers are processed with main journal 9, the left end of described bent axle main body connecting rod 2 is processed with forward spindle neck 1, the right of described bent axle main body connecting rod 2 is processed with rear main journal 8, and the surface Machining of described main journal 9 has five rod journals 7, is provided with crank arm 3 between the described rod journal 7.
In addition, the front end of described crank arm 3 is provided with vibration damper joint 5, can produce in the oscillating motion process and rocks, and is connected with vibration damper and can reduces and rock stable operation.
In addition, the rear end of described crank arm 3 is provided with oil sealing piece 6, prevents that machine oil from leaking outside along crankshaft journal.
In addition, in the described rod journal 7 equilibrium block 4 is installed, can keeps balance by whole crank shaft, in to-and-fro motion, can keep balance.
Be different from prior art, the vuilt-up crankshaft that a kind of motor of the utility model is used cooperates installation precision high, can accept moving up and down of connecting rod and become shuttling movement.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
