SU1528673A1 - Link and lever analog integrator - Google Patents

Abstract

The invention relates to instruments for reproducing math curves and improves usability. The linkage 4 is connected with the rod 7, fixed on the frame 1, with a dyad made from hinged sliders 5, 6, which holds the bypass pin. The l-shaped lever 12 is connected to the slide 4 with a cross-shaped slider 13 with one shoulder, a ring 14 is fixed on the other shoulder, in which a roller 16 with a sharp edge is mounted on the axis 15. The ring 14 is pivotally connected to the rod 7, the recording pin is mounted on the rod 7 at the point K. When the bypass pin moves along a graph of a certain function, the recording pin reproduces the graph of the integral function. 1 il.

The invention relates to instruments for reproducing mathematical curves and can be used, for example, in the educational process of universities.

The purpose of the invention is to improve ease of use.

The drawing shows the kinematic scheme of the integrate.

The tilting arm integram contains a rectangular frame 1 and means for its horizontal movement, made in the form of cylindrical rods 2 and stationary cylindrical supports 3 rigidly fastened to frame 1. On the bottom side of frame 1 is a hinged link 4, connected by a dyad of hinged sliders 5, 6 with a vertical rod 7, which is connected with the upper and lower sides of frame 1 by means of cross-shaped sliders 8, 9 with locks 9, 10, a bypass pin is installed on the dyad in the hinge 4; riva (x), and the writing pin at point K - at an arbitrarily chosen point on the plane of the drawing. The bypass pin is moved along the curve (x), while the roller 16 moves in the direction parallel to the slide 4, and the writing pin at point K draws the integral curve P (x)
