Description
Technical field
The utility model belongs to machine driven system vibration monitoring and diagnostic field, relates to a kind of comprehensive, convenient and simulate the some typical faults of bearing, gear and the base used specially of rotor unbalance fault comprehensive experiment table reliably.
Background technology
Gear distress, bearing fault and rotor unbalance are modal fault types in the machine driven system.In engineering reality, electromechanical equipment is owing to this three classes fault fails in time to find that the major accident that causes occurs repeatedly.This kind equipment is carried out status monitoring and fault diagnosis, become the active demand of large enterprise, also will bring huge economic benefit and social benefit.For teachers and students in school, contact and equipment and the situation understood in the engineering reality are necessary, but because field apparatus environment of living in and operating mode are often very complicated, when study and research, need one and conform to the principle of simplicity into difficulty, by few all many processes.Given this, one of design can model engineering reality in the experiment table of machine driven system most common failure very important theory and practical significance are just arranged.
In order to verify validity, accuracy and the relative merits at various fault Diagnosis Method, experimental study and field practice are absolutely necessary.And most existing mechanical fault simulated experiment platform, the function that has is comprehensive inadequately, often can only simulate one to two kind of equipment failure.What have approaches very much physical device, promptly as an experiment table, and its external form heaviness, complicated operation.The field of employment of experiment table is the laboratory of school or scientific research institutions, and the user of service is teachers and students in school, so press for a kind of most common failure that can simulate machine driven system, it is clean and tidy, attractive in appearance to satisfy profile again, operates light, clean experimental facilities.
Summary of the invention
Need at above-mentioned experiment, the utility model provides a kind of base used specially of fault simulation combined test table of machine drive system.
The purpose of this utility model is achieved through the following technical solutions: base is made up of first guide groove (1), second guide groove (2), distribution groove (3) and leg (4).First guide groove (1) is used to install motor, shaft coupling, axle, bearing seat, balancing disk and pinion wheel.Second guide groove (2) is used to install gear wheel, bearing seat, shaft coupling and detent.Distribution groove (3) is used to install electric machine controller, brake controller, data line through position.The bottom of described base used specially is a day font bottom surface (11).Respectively designed a counterbore (12) on the leg (4), be used for by bolt base and ground being fixed, counterbore can make the complete assembling of experiment table back attractive in appearance succinct.The upper design of the public cell wall of described first guide groove (1), second guide groove (2) and distribution groove (3) has boss 9.Through hole 8 on the cell wall of described base is used to pass the sensing data line, makes all wirings all be hidden in guide groove inside, reaches the purpose of neat appearance.The last end face of described base designs between first guide groove (1), second guide groove (2), distribution groove (3) the uniform threaded hole that installs and fixes (5) that is used for each parts of experiment table of 3 row.Design has uniform muscle (10) on the cell wall of described base.
Described uniform threaded hole (5) is used for installing and fixing of each parts of experiment table, and can be according to the axial location of the flexible adjustment component of actual operating position, changing the support stiffness of axle, thereby changes the radial displacement of axle.
Described first guide groove (1) design fluted (6) is used to lay motor.Design fluted (7) is used to lay gear pair in described first guide groove (1) and second guide groove (2), can effectively prevent to interfere between gear pair and the base.
The radial location benchmark that described boss (9) is installed for bearing seat when bearing seat is installed, is close to boss (9), makes the gear pair that is installed on the axle satisfy radially assembly precision.Because the gear pair assembly precision requires high, so positioning reference must high-precision processing, this boss design can reduce working (finishing) area and difficulty of processing significantly.
Described muscle (10) respectively has one in the both sides edge of groove (7), evenly distributes to both sides separately then.
Font bottom surface (11) design in described day, be because the experiment table requirement wants level steady fixedly the time, so the bottom surface of base is processed with very high accuracy requirement, the design of day font greatly reduces the base end face and the surface of contact of ground basal plane, thereby reduces the processing cost and the difficulty of processing of base.
Described base is the cast aluminium alloy casting, and finishing forms then.Use cast aluminium alloy that light weight is arranged, cost is low, and post-production is advantage easily, and can satisfy performance requirement fully.
Advantage of the present utility model is: the design aim of this base is under the situation that satisfies the experiment table Essential Performance Requirements, makes the experiment table total arrangement succinct, neat, and part replacement, easy to adjust is made processing economy, feasible.
