Description
Technical field
The present invention relates to a kind of experimental provision that rotating mechanism is carried out the transient equilibrium operation, is a kind of dynamic balancing test device of rigid double-disk rotor specifically, and this device is equipped with two balancing frames on a fixed rotating shaft.
Background technology
At present, the equipment of many high-speed rotation in engineering, its rotor are not desirable symmetrical rigid bodies, exist error when Bearing Installation yet.So can produce unbalanced inertial force during work, cause very big bearing constraining force.Existing large and small type experiment of dynamic balancing device category is a lot, but general complex structure, inconvenient operation, the dynamic balancing test device that is fit to college experiment teaching is actually rare.There are a kind of four disk rigid rotator experiment of dynamic balancing equipment at present, can supply student's independent operation in education experiment.But it is too complete that its weak point is the dedicated processes program, also improved cost thus, and the student lacks the space of thinking independently in the experimental implementation process.For these reasons, this develops the rigid rotator dynamic balancing test device is exactly on the basis with reference to existing same category of device, and it is compact more to design structure, cost is cheaper, clear physics conception, directly perceived, it is convenient to adjust use, is more suitable for the experimental provision that college teaching uses.
Summary of the invention
The objective of the invention is to overcome the weak point that exists in the above-mentioned technology, a kind of compact conformation is provided, reasonable in design, composite behaviour is strong, is convenient to install the dynamic balancing test device of rigid double-disk rotor of multiple test accessories.
In order to achieve the above object, the technical solution used in the present invention is: bearing seat is fixed on the elastic support, the support arm lower end part is fixedlyed connected with elastic support, photoelectric displacement sensor is installed on the support arm, by elastic support, bearing seat, support arm and photoelectric displacement sensor common combination bearing in aggregates.Rotating shaft is installed on the elastic support by bearing seat, rotating shaft one end is connected with motor by shaft coupling, motor mounting is on motor cabinet, the left and right balancing frame of symmetry is housed in the rotating shaft, the outside spiral-lock of left and right balancing frame has transparent shroud, motor cabinet, transparent shroud and elastic support are by being bolted on the base, and the base lower end is equipped with shock bracket.
Advantage of the present invention is:
Because elastic support, bearing seat, support arm and photoelectric displacement sensor common combination bearing in aggregates have shortened the distance between photoelectric displacement sensor and the test point, connect good rigidly, reduced vibration interference, improved measuring accuracy.The signal output of photoelectric displacement sensor is stronger, has solved the too small problem of support displacement semaphore.Upper/lower terminal at elastic support is respectively equipped with a pair of mounting groove, is convenient to install multiple test accessories.This device can carry out experiment of dynamic balancing by external oscillograph, the student shows according to oscillographic reading and loads adjustment, can see intuitively that the vibration of supports displacement reduces with progressively near dynamically balanced process, clear physics conception not only, and reduced cost.
