Abstract
The utility model belongs to an experimental device applicable for teaching demonstration and practical training by an equipment fault diagnosis technology. The experimental device is to solve the disadvantages that the experimental device in the prior art has complex structure, can not meet any condition in weight adjustment, has low measuring accuracy, hidden dangers of safety, etc. and is not used for teaching, practice training, etc. The experimental device has the following technical measures that: the experimental device for measuring the dynamic balance of a rotor in teaching consists of a direct current motor (1), a shaft (2) on two ends of the direct current motor (1), a speed governor (3) connected with the direct current motor (1), an experimental rotor (4) connected with the shaft (2) on two ends, a pedestal (11) for fixing the motor, a sensor (7) arranged on a bearing seat (5) of two ends of the shaft (2) and a nut (12) for fixing the rotor (4). Holes (8) are processed on the rotor (4); and the outer edge of the rotor (4) is provided with a guard ring (9). The experimental device is suitable for teaching, practice training, meets any weight adjustment, has safe and reliable operation and high measuring precision and can be also used for demonstration by a diagnostic instrument manufacturer.
Description
Technical field
The utility model relates to measurement mechanism, specifically belongs to the experimental provision of the measurement rotor dynamic balancing of the teaching demonstration that is applied to Diagnosis Technique and real training.
Background technology
What existing vibration survey and experiment of dynamic balancing measurement mechanism were adopted is the rotor test platform of producing one's early years, and this device makes and takes up an area of complex structure greatly, especially price height (4500 yuan/platform of acquisition cost) because rotor is many, supporting-point is many, axial length.And the test mass that this device is adopted in the teaching demonstration test is a primary screw, can not satisfy " arbitrarily " condition when weight is regulated, and measuring accuracy is not high simultaneously, has potential safety hazard etc., and is not teaching and hands-on training experimental provision.
The utility model content
The utility model is to solve above-mentioned deficiency, provide a kind of be specially adapted to impart knowledge to students and hands-on training, simple in structure, satisfy any weight is regulated, handling safety is reliable, with low cost teaching with the experimental provision of measuring rotor dynamic balancing.
Solve the technical measures of above-mentioned deficiency:
The teaching experimental provision of measuring rotor dynamic balancing, by the axle at direct current generator, direct current generator two ends, the speed regulator that is connected with direct current generator, form with the base of the experiment rotor that spool is connected at two ends, fixed electrical machinery, nut that sensor, fixed rotor be housed on the bearing seat at axle two ends, it is; On rotor processing porose, the rotor outer rim is equipped with guard ring, balancing weight is a plasticine.
It is: test epitrochanterian hole and be at least two, and evenly arrange.
It is: the sensor of adorning on the bearing seat at axle two ends is for radially installing.
It is: the collar is housed on the bearing seat at axle two ends in addition, and sensor is contained on the collar.
Characteristics of the present utility model are specially adapted to teaching and hands-on training, simple in structure, satisfied weight are arbitrarily regulated, handling safety is reliable, with low cost, the measuring accuracy height, not only satisfied the requirement that the student takes action on one's own to operate, make teaching, training reach theoretical and the actual purpose that combines, also can be used for the do demonstration of diagnostic instrments producer and promote the instrument of oneself.

Embodiment
Be described in further detail below in conjunction with accompanying drawing:
The teaching experimental provision of measuring rotor dynamic balancing: this device, because bearing seat (5) outer ring thickness low LCL, so on the bearing seat (5) at axle (2) two ends the collar (6) is housed, sensor (7) adopts engage thread to install with the collar (6), and the collar (6) adopts wringing fit with bearing seat (5).The disc rotor (4) in 8 holes (8) that process evenly distributing is set in axle (2) one or both ends in the collar (6) outside, and the opposite side of disc rotor (4) is made axial restraint with screw thread (12); Direct current generator (1) carries out routine with speed regulator (3) and is connected; At the guard ring (9) of disc rotor (4) outer rim suit rubber material, it is hidden hole (8); Radially sensor installation (7) at the collar (6).During experiment guard ring (9) is offset slightly and can adds and subtracts plasticine balancing weight (10) in hole (8), direct current generator (1) is connected in base (11).
Principle of work
Start direct current generator (1), by the speed of experiment requirement, with speed regulator (3) speed governing degree; Behind surveying instrument measurement rotor initial vibration, press the prompting of surveying instrument and Survey Software, in the radial hole (8) on experiment disc rotor (4), the test mass plasticine that adds deduct is finished until experiment.Because adopting plasticine is balancing weight, therefore, can select the weight of test mass easily, satisfy the condition of " test mass is any ", improve measuring accuracy.In order to prevent that test mass plasticine from flying away from because of centrifugal force, cause and can not normally test and security incident, with guard ring (9) it is hidden hole (8) sealing, guard ring (9) is the rubber material.
Claims (4)
1, the teaching experimental provision of measuring rotor dynamic balancing, form by the base (11) of axle (2), the speed regulator (3) that is connected with direct current generator (1) at direct current generator (1), direct current generator (1) two ends, the experiment rotor (4) that is connected with spool (2) at two ends, fixed electrical machinery, nut (12) that sensor (7), fixed rotor (4) be housed on the bearing seat (5) at axle (2) two ends, it is characterized in that; Go up processing porose (8) at rotor (4), rotor (4) outer rim is equipped with guard ring (9), and balancing weight (10) is a plasticine.
2, the teaching as claimed in claim 1 experimental provision of measuring rotor dynamic balancing, it is characterized in that: the hole (8) on the experiment rotor (4) is at least two, and evenly arranges.
3, the teaching as claimed in claim 1 experimental provision of measuring rotor dynamic balancing is characterized in that: the sensor (7) that the bearing seat (5) at axle (2) two ends is gone up dress is radially installation.
4, the teaching as claimed in claim 1 experimental provision of measuring rotor dynamic balancing, it is characterized in that: on the bearing seat (5) at axle (2) two ends the collar (6) is housed in addition, sensor (7) is contained on the collar (6).
