Abstract
The utility model discloses an integral crankshaft with an oil throwing function, which comprises a crankshaft body, wherein a connecting block is arranged on a shaft head of the crankshaft body extending out of a crankcase, and the connecting block is matched with a coupling, and is characterized in that: the oil slinger is integrally formed with the crankshaft body, a first bearing bush mounting part is arranged between the oil slinger and one side of the crank, and a second bearing bush mounting part is arranged on the other side of the crank. The oil slinger and the crankshaft are integrally formed in one step, and the oil slinger is high in precision, low in cost, safe and reliable.
Description
Technical Field
The utility model relates to an improved utility model of a compressor crankshaft, in particular to an improved utility model of an integral crankshaft with an oil throwing function.
Background
The crankshaft is an important component of the crank-connecting rod mechanism and consists of a crankshaft body, an oil slinger, a connecting bolt and other secondary components. Because the crankshaft needs to transmit the rotation power of the motor, the crankshaft head needs to extend out of the crankcase to connect the coupling, and the extending part needs to consider the problem that oil cannot leak to the outside of the crankcase, therefore, referring to fig. 3, a split type oil slinger 9 is usually arranged at the position of the crankshaft journal and is formed by connecting bolts 10, however, stress concentration is easy to occur at the lug parts of the mounting bolts, the oil slinger has hidden danger of cracking, and even the loosening of the bolts easily causes safety accidents.
Disclosure of Invention
The utility model aims to solve the technical problem of overcoming the defects of the prior art and providing an integral crankshaft with an oil throwing function.
In order to solve the technical problems, the utility model is realized by adopting the following technical scheme: this kind of from whole bent axle of taking oil slinging function, including the bent axle body, be equipped with the connecting block on the spindle nose that the bent axle body stretches out the crankcase, this connecting block cooperatees its characterized in that with the shaft coupling: the oil slinger is integrally formed with the crankshaft body, a first bearing bush mounting part is arranged between the oil slinger and one side of the crank, and a second bearing bush mounting part is arranged on the other side of the crank.
The outer side surface of the oil slinger is set to be a plane, and the inner side surface of the oil slinger is set to be a conical surface.
The taper of the conical surface is 20-40 degrees.
Longitudinal parting strips which are distributed at intervals along the circumferential direction are arranged on the conical surface.
The improved integral crankshaft with the oil slinging function has the advantages that the oil slinging ring and the crankshaft are designed into a whole, and the integral crankshaft is not connected by bolts, so that potential safety hazards caused by loosening of the bolts are avoided; and the oil slinger and the crankshaft are integrally formed by one-step processing, so that the precision is high and the structural design space is large.
Drawings
The following describes the embodiments of the present utility model in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is a diagram showing the construction of the slinger of the present utility model.
Fig. 3 is a diagram of a split type crankshaft structure in the background of the utility model.
Detailed Description
The drawings illustrate the structure of the present utility model, and details thereof are further described below with reference to the drawings. In this embodiment, referring to fig. 1-2, this integral crankshaft with oil slinging function, including crankshaft body 1, be equipped with connecting block 2 on the axle head that crankshaft body 1 stretches out the crankcase, this connecting block 2 cooperatees with the shaft coupling, the journal position of crankshaft body 1 is equipped with the oil slinger 3, and this oil slinger 3 is integrated into one piece with crankshaft body 1, does not need bolted connection to eliminate the lug position of mounting bolt and produce stress concentration easily, the oil slinger 3 has the hidden danger of fracture to and stopped the potential safety hazard that takes place because of the bolt looseness, be first axle bush installation department 5 between oil slinger 3 and the crank 4 one side, the crank 4 opposite side is second axle bush installation department 6.
As a further improved specific embodiment, the outer side surface of the oil slinger 3 is set to be a plane, the inner side surface of the oil slinger 3 is set to be a conical surface 7, and the conical surface 7 forms an oil blocking surface, so that oil slinger is convenient to use.
As a further improved specific embodiment, the taper of the conical surface 7 is 20-40 degrees.
As a further improved specific embodiment, the conical surface 7 is provided with longitudinal parting strips 8 which are distributed at intervals along the circumferential direction, and the longitudinal parting strips 8 play a role in assisting oil throwing.
In summary, the above embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
Claims (4)
