Abstract
The invention discloses an anti-sinking flywheel, which comprises a flywheel main body, magnetic steel arranged in the flywheel main body and a balancing weight arranged on the flywheel main body, wherein a central insert is embedded in the middle of the flywheel, and a mounting hole matched with the central insert is formed in the center of the flywheel main body.
Description
Technical Field
The invention belongs to the technical field of flywheels, and particularly relates to an anti-sinking flywheel.
Background
The traditional flywheel is formed by directly die-casting polar claws, magnetic steel and a balance weight, the center part of the main body of the flywheel is made of aluminum alloy, and the flywheel has relatively low hardness and is unstable; and the smoothness is not very stable due to the surface treatment of the central part, so that the contact surface is not enough, the flywheel is not tightly matched with the crankshaft during installation, and relative sliding is generated. And finally, adverse factors are generated on the installation of the whole machine.
Disclosure of Invention
The invention provides an anti-sinking flywheel for overcoming the defects of the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme: a sinking-prevention flywheel comprises a flywheel main body, magnetic steel arranged in the flywheel main body and a balancing weight arranged on the flywheel main body, wherein a central insert is embedded in the middle of the flywheel, and a mounting hole matched with the central insert is formed in the center of the flywheel main body; the center part of the flywheel main body is smoother by combining the flywheel main body with the center insert, and the center part of the flywheel main body and the crankshaft can be more closely matched together, so that the flywheel and the crankshaft are prevented from generating excessive relative sliding during installation; when the flywheel needs to be torqued during installation, the small flywheel is generally between 15N.m and 20N.m, so that certain deformation can be generated when the central part of a product is made of aluminum alloy after stress application, the whole flywheel sinks, and meanwhile, when the flywheel sinks, the matching part of the central part of the flywheel and a crankshaft is increased, the central part of the flywheel cracks, and the serious safety problem is generated. The flywheel adopting the central insert has the advantages that the hardness of the central part of the flywheel is enhanced, the central part of the flywheel cannot deform when the force is applied, so that the flywheel cannot sink, the matching part of the central part of the flywheel and a crankshaft does not change when the flywheel does not sink, and the central part of the flywheel cannot crack.
In a word, the flywheel adopting the central insert can improve the hardness and the smoothness of the flywheel so as to improve the strength of the flywheel and the tightness of the crankshaft fit, so that the flywheel can be used for a longer time, and the safety problem generated by the flywheel is greatly reduced. Therefore, the service efficiency and the service life of the product are improved, and a large amount of cost is saved.
The invention abandons the traditional mode that the taper hole is directly formed by aluminum alloy through die casting, and utilizes the central iron piece as the taper hole of the flywheel, thereby greatly prolonging the service life of the product, improving the qualification rate and the utilization rate of the product and reducing the production cost.
Preferably, the mounting hole is provided with a first protrusion and a second protrusion, and the central insert is provided with a first clamping groove matched with the second protrusion.
Preferably, the central insert is provided with a through hole in the middle, and the through hole is flared.
Preferably, the central insert is provided with a limiting boss, and the cross section of the limiting boss is in a regular hexagon shape.
Preferably, the central insert is an iron piece.
In conclusion, the flywheel with the central insert can improve the hardness and the smoothness of the flywheel so as to improve the strength of the flywheel and the tightness of the crankshaft fit, so that the flywheel can be used for a longer time, and the safety problem generated by the flywheel is greatly reduced. Therefore, the service efficiency and the service life of the product are improved, and a large amount of cost is saved.

Detailed Description
As shown in fig. 1-3, an anti-sinking flywheel comprises a flywheel body 1, a pole claw 2 arranged on the flywheel body, a magnetic steel 3 arranged in the flywheel body, and a balancing weight 5 arranged on the flywheel body, wherein a central insert 4 is embedded in the middle of the flywheel body 1, and a mounting hole 41 matched with the central insert is arranged in the center of the flywheel body; the center part of the flywheel main body is smoother by combining the flywheel main body with the center insert, and the center part of the flywheel main body and the crankshaft can be more closely matched together, so that the flywheel and the crankshaft are prevented from generating excessive relative sliding during installation; when the flywheel needs to be torqued during installation, the small flywheel is generally between 15N.m and 20N.m, so that certain deformation can be generated when the central part of a product is made of aluminum alloy after stress application, the whole flywheel sinks, and meanwhile, when the flywheel sinks, the matching part of the central part of the flywheel and a crankshaft is increased, the central part of the flywheel cracks, and the serious safety problem is generated. The flywheel adopting the central insert has the advantages that the hardness of the central part of the flywheel is enhanced, the central part of the flywheel cannot deform when the force is applied, so that the flywheel cannot sink, the matching part of the central part of the flywheel and a crankshaft does not change when the flywheel does not sink, and the central part of the flywheel cannot crack.
In a word, the flywheel adopting the central insert can improve the hardness and the smoothness of the flywheel so as to improve the strength of the flywheel and the tightness of the crankshaft fit, so that the flywheel can be used for a longer time, and the safety problem generated by the flywheel is greatly reduced. Therefore, the service efficiency and the service life of the product are improved, and a large amount of cost is saved.
The invention abandons the traditional mode that the taper hole is directly formed by aluminum alloy through die casting, and utilizes the central iron piece as the taper hole of the flywheel, thereby greatly prolonging the service life of the product, improving the qualification rate and the utilization rate of the product and reducing the production cost.
Preferably, the mounting hole 41 is provided with a first protrusion 42 and a second protrusion 43, and the central insert is provided with a first locking groove 44 matched with the second protrusion.
Preferably, the central insert 4 is provided with a through hole 45 in the middle, and the through hole is flared.
Preferably, the central insert 4 is provided with a limiting boss 46, and the cross section of the limiting boss is regular hexagon.
Preferably, the central insert is an iron piece.
