SU10153A1 - A device for converting coaxial crank through dead spots - Google Patents

Description

The proposed device aims at translating the paired crank through dead spots by applying springs acting on the paired crank pin.

On the schematic drawing phi1. 1 is a front view of a proposed fixture; FIG. 2-part coupled crank.

The proposed fixture consists of two identical helical springs 1 and 2 connected with a finger on a coupled crank k and fixed at points a and b, located at equal distances from the center line c, paired cranks perpendicular to it, reconstructed from points with “linear with springs crank. For reverse rotation, the points of attachment of the springs are moved to points Oi and bi. The twin crank k is set in motion with the help of an eccentric g mounted on the crankshaft. Regulation of tension springs produced

by moving the anchorage points a and 6, respectively, along the lines JL and MN,

In the position shown in FIG. 1, the spring 2 (hypotenuse) has a tension greater than the spring 1 (the leg) and the difference in tension of the springs translates the finger of the coupled crank through an upper dead center. At the bottom dead center, the spring 2 (the leg) has a lower tension than that of pressure 1 (hypotenuse) and the difference in spring tension also translates the finger of the paired crank through the bottom dead center.

The proposed device also serves as a regulator of engine speed and automatic switch when stuck. As the engine rpm increases, pb are the inertial forces of the opposite direction, and at the start of a jam, the amount of friction work increases. To overcome their cumulative effect, the difference in the corresponding spring tension will not be sufficient and the engine will lower

rotational speed, and the twin crank will oscillate until the engine stops.

The subject of the patent.

A device for converting a coupled crank through dead spots, characterized by the use of two

identical coil springs 1 and 2 acting on a pin of a coupled crank and fixed with adjustable tension at points a and 6 (or O and hi-when reversing rotation), located at the same distance from the line of centers of paired cranks on perpendiculars recovered from the dead points of the crank connected to the springs.
