Mechanical balance experiment instrument

Abstract

The invention relates to a mechanical balance experiment instrument which comprises a supporting mechanism, a power mechanism and a balance adjusting mechanism. The supporting mechanism comprises a base, fixed supporting rods arranged at the two ends of the base and a lengthening plate arranged at one end of the base. Supporting rods are arranged at the upper ends of the fixed supporting rods in a matched mode. The power mechanism comprises a motor, a reduction gear device, a rotary main shaft and a short shaft. The balance adjusting mechanism comprises a vectorial resultant balance mechanism, a vibration display mechanism, a stiffness and resilient mounting and switching mechanism and a tray lifting mechanism. The vibration of the rotary main shaft is amplified, the amplitude of the vibration can be judged according to the position of a light spot emitted by a laser pen on a screen, and therefore the visualization of microvibration is achieved. A standard mass block is moved, the position of a chuck body is changed, a dynamic balance principle experiment can be changed from a single replication experiment into a design experiment, the hands-on practice capacity of students can be trained greatly, and the perceptual knowledge of the students is improved.

Description

technical field [0001] The invention relates to a mechanical balance device, in particular to a mechanical balance experiment instrument. technical background [0002] In the mechanical class, there are many very important principles, and dynamic balance is one of them. The principle of dynamic balance is often used in the design of machinery, but it is difficult to understand in the process of learning. When the teacher teaches this part of knowledge, there are a lot of mathematical derivation process and simple picture display, which cannot let the students form an intuitive Impression, it is difficult to understand. Let the students verify this principle by themselves through experiments, which can deepen their understanding, and the actual operation also makes students deeply impressed by this principle. But the function of the existing dynamic balance experiment instrument is simple, can only find the mass-diameter product of the unbalanced mass in the same plane, can...

Problems solved by technology

But the function of the existing dynamic balance experiment instrument is simple, can only find the mass-diameter product of the unbalanced mass in the same plane, cannot determine the mass-diameter product of the unbalanced mass in more than two different planes by the double-sided balance method, and The essence of dynamic balance is the application of double-sided balance method. The existing experimental equipment cannot let students understand the principle of dynamic balance fundamentally.
