Description
Technical field
The present invention relates to flywheel, relate in particular to and a kind ofly can automatically keep dynamically balanced flywheel structure.
Background technique
Comprise a large amount of component that rotate in conventional machinery, such as rotor of various transmission shafts, main shaft, motor and steam turbine etc., be referred to as solid of rotation.The pressure that countershaft produces is the same when not rotating solid of rotation when rotation in ideal conditions, and such solid of rotation is called the solid of rotation of balance.And flywheel requires it is designed to the solid of rotation of balance as having suitable rotary inertia, working the rotary member of storing and discharging the kinetic energy effect.But due to material is inhomogeneous or blank defect, processing and assembling in produce error, design the time just there is the many factors such as asymmetrical geometrical shape, make flywheel when rotated, the centrifugal inertia force that on it, each small particle produces can not be cancelled out each other, and also is nonequilibrium solid of rotation, can not keeps transient equiliblium.The centrifugal inertia force of the flywheel of non-dynamic balance is applied to machinery by rotating shaft and basis is upper, can cause vibration, produce noise, accelerated wear test, has shortened mechanical life, when serious, can damage incidents.For this reason, must carry out balance to flywheel, make its balance accuracy grade that reaches permission, the mechanical vibration amplitude produced because of imbalance is fallen in allowed limits.The existing method that flywheel is remained in the balance quality scope is the duplicate removal method,, in flywheel working process, by dynamic balancing machine, finds amount of unbalance, then removes unnecessary quality by the method for machining, thereby make flywheel meet requirement for dynamic balance.But can only make in this way flywheel there is satisfactory balance quality under non-working condition, and due to the error produced in assembling, use in the reasons such as dirty, wearing and tearing of flywheel, under non-working condition, the balance quality of the satisfactory flywheel of balance quality under the use state may be undesirable.
At number of patent application, be 94191268.x, open day is on March 6th, 1996, and name is called and discloses a kind ofly for the flywheel on automobile in the patent documentation of " vibration damper flywheel that is mainly used in automobile ", and it can not automatically keep balance as existing other flywheel.
Summary of the invention
The invention provides and a kind ofly under the use state, can automatically keep dynamically balanced flywheel structure, solved that existing flywheel can only have satisfactory balance quality under non-working condition and the problem that likely do not meet the balance quality requirement under the use state.
Above technical problem solves by following technical proposal: a kind ofly can automatically keep dynamically balanced flywheel structure, comprise the flywheel main body, also comprise dynamic balancing machine, control gear and with the injection apparatus of described flywheel main body coaxial rotation, described control gear is electrically connected with described dynamic balancing machine and injection apparatus, described injection apparatus comprises liquid storage cylinder and several nozzles that can open separately, described liquid storage cylinder is connected with described nozzle, described flywheel main body is provided with several along the weightening finish spaced apart from each other chamber circumferentially distributed, described weightening finish chamber is provided with import, each in described import is at least with an alignment in described nozzle." weightening finish chamber " refers to for holding the cavity of the object sprayed into through injection apparatus.To inject liquid storage cylinder for increasing the fluid (hereinafter referred to as weightening finish glue) of flywheel body weight in using process, in the flywheel main body under the use state and while having reached desired rotating speed, whether the balance quality that detects the flywheel main body by dynamic balancing machine meets the requirements, if undesirable, dynamic balancing machine flows to control gear by data, that position how many amounts that need to increase weight of informing the flywheel main body just can meet the balance quality requirement, after control gear is received signal, control gear is controlled the nozzle of the correspondence of injection apparatus and is opened, weightening finish glue in liquid storage cylinder is sprayed onto the corresponding position to the flywheel main body in corresponding weightening finish chamber through this nozzle and corresponding import and is increased weight, so that the flywheel main body reaches the balance quality requirement.Nozzle and import can arrange one by one over the ground, also can one the corresponding two or more nozzles of import, guarantee that when having portion nozzle to damage still old weightening finish glue is sprayed onto in the weightening finish chamber, improve reliability of the present invention.Design a plurality of injection apparatus and each injection apparatus only has one or belong to the protection domain of injection apparatus of the present invention with the structural type of top nozzle.All nozzles can share same liquid storage cylinder, also can design as required a plurality of liquid storage cylinders.
As preferably, the liquid chunnel that described liquid storage cylinder is connected with described nozzle is positioned at the axis of an end of described liquid storage cylinder towards described flywheel main body.This kind of design, in the process of rotating, due to the effect of centrifugal force, the weightening finish glue in liquid storage cylinder can the automatic stream nozzle, thereby does not need external force to drive the weightening finish solation to nozzle.
As preferably, the present invention includes and control the control valve that described nozzle opens and closes.If while needing by which nozzle ejection weightening finish glue, make to control control valve that this nozzle opens and closes and open and get final product, on the contrary closed control valve.
As preferably, described control valve is solenoid valve.Be convenient to realize automation control.
As preferably, described control gear and described injection apparatus link together, and described control gear is provided with signal receiver, and described dynamic balancing machine is provided with signal transmitter, and described signal transmitter is for transmitting to described signal receiver.By wireless mode, communicate, convenient while communicating between the parts that rotate and the parts that do not rotate.
As preferably, described injection apparatus is detachably connected on and drives in the rotating shaft that described flywheel main body rotates.Can as required dynamic balancing machine, control gear and injection apparatus etc. be pulled down or install, alternative good.
As preferably, described nozzle is with between described flywheel main body, having gap.Avoid nozzle to exert an influence to the balance of flywheel main body.
The present invention has following advantage: by design weightening finish chamber on the flywheel main body with under the use state, can give as required the weightening finish mechanism that weightening finish glue is sprayed in chamber, whether the online balance quality that detects the flywheel main body meets the requirements, do not meet and adopt in real time incremental method to be proofreaied and correct, therefore can guarantee that the flywheel main body maintains at any time enough balance qualities under the use state.
