Problems solved by technology

[0002] At present, the known rotating shaft angular velocity measuring devices are mainly electronic, and the angular acceleration can be calculated through the electronically measured angular velocity. At present, there is no ready-made independent mechanical rotating shaft angular acceleration measuring device on the market, let alone an independent mechanical rotating shaft angular velocity measuring device. Acceleration switch device; patent application number 201010130636.X "Mechanical Shaft Angle Super Acceleration Switch Device" adopts the method of space cam pair to make the axially moving push plate trigger the travel switch. be promoted and applied

example 1

[0023] See figure 1 with figure 2 As shown, figure 1 with figure 2 Shown is a specific embodiment of the mechanical slider type angular super acceleration switch device of the present invention, including the main shaft 1, the bearing 2, the housing 3, the bearing 4, the counterweight disk 5, the inertia disk 6, the slider 7, and the cover plate. 8. Tension spring 9, roller seat 10, travel switch 11 and roller 12, the rotation of the outside is transmitted through the main shaft 1 installed in the base, and the inertia disk 6 is installed through the bearing 4 The main shaft 1 forms a rotating pair with the main shaft 1, the roller seat 10 is fixed on the main shaft, the slider 7 is installed in the groove of the inertia disk 6 and the cover plate 8 is installed, so that the slider 7 and the inertia disk 6 constitute a moving pair , The moving direction of the slider 7 is along the radial direction of the main shaft 1, a tension spring 9 is installed between adjacent sliders 7...

example 2

[0027] For instance two, please see image 3 with Figure 4 As shown, Example 2 is a modification of Example 1, which is basically the same as figure 1 with figure 2 The specific embodiments shown are the same, and the same parts use the same reference numerals. Compared with Example 1, the extension spring 9 is reduced in the second example, and the O-shaped spring 13 is added; the O-shaped spring 13 and the extension spring 9 With the same function, the O-shaped spring 13 exerts a force on the slider 7 to always point to the rotating shaft, and the greater the distance between the slider 7 and the rotating shaft, the greater the force of the O-shaped spring 13 on the slider 7.

Abstract

The invention relates to a mechanical sliding block type angular super-acceleration switching device, the external rotation is introduced through a main shaft mounted in a base, an inertia disk is mounted on the main shaft through a bearing and constitutes a rotation pair together with the main shaft, sliding blocks are mounted on the inertia disk and constitute a movement pair together with the inertia disk, the sliding blocks are moved in the radial direction of the main shaft, a spring is arranged on each sliding block, a roller seat is fixed on the main shaft, rollers in the same effective number with the sliding blocks are mounted on the roller seat, and the sliding blocks are always in contact with the rollers under the action of the springs. According to the invention, angular acceleration is transfromed to the displacement of an indication part in a mechanical mode, a travel switch mounted on the base is triggered to alarm when the acceleration achieves the set value, and the set value of the acceleration can be adjusted by adjusting the moment of inertia of the inertia disk as well as the stiffness and original length of each spring. The design is skillful and compact, the structure is simple, the mechanical sliding block type angular super-acceleration switching device is economical and reliable, and the range of applications is wide. An alarm can be rapidly given out at the initial stage that the rotational speed of a mechanical rotating shaft is out of control.

Description

Technical field [0001] The invention relates to the technical field of acceleration measuring devices, in particular to the technical field of rotating shaft angular acceleration measuring devices, in particular to a mechanical slider type rotating shaft angle super-acceleration switch device, especially a switch capable of identifying dangerous angular acceleration. Background technique [0002] At present, the known rotating shaft angular velocity measurement devices are mainly electronic, and the angular acceleration can be calculated from the electronically measured angular velocity. At present, there is no ready-made independent mechanical rotating shaft angular acceleration measurement device on the market, and there is no independent mechanical rotating shaft angular acceleration. Acceleration switch device; the patent "Mechanical Rotary Axis Angle Ultra-Acceleration Switch Device" with the application number 201010130636.X uses a spatial cam pair method to cause the axiall...
