Abstract
An irregular dynamic balance flywheel comprises a friction surface and a crank shaft surface, wherein a friction piece positioning hole is formed in one side of the friction surface, a central hole is formed in one side of the crank shaft surface, the friction piece positioning hole is communicated with the central hole, and a crank shaft spiral hole and a crank shaft positioning pin hole are formed in the outer circumference of the central hole. The flywheel further comprises an unbalanced block, wherein the unbalanced block is a metal block located on the crank shaft surface and is of a sector structure formed by two concentric fan-shaped arcs sharing the same central angle, and the two concentric fan-shaped arcs are an outer arc and an inner arc. Due to the fact that the unbalanced block is arranged on the crank shaft surface in a matching mode according to the unbalanced structure of a crank shaft and eliminates unbalanced moment and bending moment produced when an integrated body of the flywheel and the crank shaft is in a high-speed operation process, and stationarity of operation of an automobile is improved.
Description
Technical field
The utility model relates to a kind of auto parts and components, and is particularly a kind of for the Automobile flywheel that transmits automobile power.
Background technique
Automobile flywheel is the Passive part of starter motor and the driving link of clutch as a kind of auto parts and components, for the operation of automobile provides the effect of transferring power, thereby, belong to important spare part indispensable in the automobile manufacture industry.The main effect of flywheel is exactly the storage of carrying out energy, makes the revolution nonuniformity of bent axle in operation process be eased.Bent axle during work usually is in the state that runs up, will produce irregular centrifugal force and centrifugal moment at rod journal, the crank pin place of bent axle like this, and existing flywheel often all is the structure of regular shape, gravity balance, therefore the composite structure body that forms after flywheel is connected with bent axle remains a structure that is easy to generate centrifugal force and centrifugal moment, thereby make motor produce vibration greatly, this vibration has not only caused the motion noise, also accelerate the wearing and tearing of flywheel and bent axle, increased the maintenance cost of equipment.
The model utility content
At prior art problems, the utility model provides irregular dynamically balanced novel flywheel, unbalance moment and moment of flexure that this flywheel effectively exists in the balance crankshaft system, effectively improve the stationarity of automobile runs, reduced the wearing and tearing of run up motion noise and flywheel and bent axle.
The technical solution of the utility model is: irregular dynamic balancing flywheel, comprise rubbing surface and bent axle face, and a side of described rubbing surface is provided with the friction plate positioning hole, and a side of described bent axle face is provided with center hole, and described friction plate positioning hole is communicated with center hole; The outer circumference of described center hole is provided with bent axle spiral hole and bent axle positioning pin hole; Described flywheel also comprises uneven piece, and described uneven piece is the slug that is positioned on the bent axle face; Described uneven piece is two identical sector shape structures that concentric fan-shaped circular arc is formed of central angle, and described two concentric fan-shaped circular arcs are respectively outer arc and inner arc.
Preferably, described central angle is the 30-45 degree, angle between the line at described bent axle positioning pin hole and flywheel center and the symmetrical center line of uneven piece is 12 degree or 18 degree or 25 degree, the radius of described outer arc is 140-160mm, the radius of described inner arc is 120-130mm, and the thickness of described uneven piece is 10-12mm.
Preferably, described central angle is 45 degree, and the angle between the symmetrical center line of the line at described bent axle positioning pin hole and flywheel center and uneven piece (3) is 18 degree, and the radius of described outer arc is 147mm, the radius of described inner arc is 126mm, and the thickness of described uneven piece is 11.5mm.
The beneficial effects of the utility model are: the utility model arranges uneven piece according to the unbalanced construction of bent axle at the bent axle face of coupling flywheel, described uneven piece has been eliminated unbalance moment and the moment of flexure that the integral body behind flywheel and the bent axle composition produces in the process of running up, thereby improves the stationarity of automobile runs.
