SU27292A1 - Speed box, smoothly changing the speed of the gear shaft connected to it - Google Patents

Description

The invention relates to equipped with conical friction clutches and a spring for adapting smoothly the number of revolutions transmitted from one shaft to another.

The proposed gearbox is intended for operating under varying conditions. loads of engines (for example, automobile engines, pregnant-current electric motors, etc.), which have a constant number of heaters.

With the help of the proposed speed cutter, it is intended to automatically change the engine tune, for example, in accordance with SIZE load. - The parts of the working split shaft of the correction frame are interconnected by means of a corresponding spring: a read spring. During the work, when the load is steady, both shaft clock rotates at the same speed. When increasing the load on one part of the shaft, the latter will slightly lag behind the leading one and this lag will occur until the additional load is balanced by the additional copelling of the spring after which the shaft parts shifted relative to each other around the circumference begin to rotate again with; one speed.

By changing the speed, it turns into a straight-line parallel to the axis of the shaft, communicating through a gear system to a roller located between the end; ches friction drums connected to the drive and transmission shafts.

The box operates in such a way that, as the load on the entire installation increases, the speed on the shaft, for example, going out to the wheels of the car, etc., decreases while the engine maintains its revolutions. It is assumed that the proposed gearbox may help eliminate the risk of engine overload, reduce its wear, as well, in a case. for use in vehicles with frictional transmission, - to prevent harmful, wheel slip, etc.

In FIG. 1 shows a longitudinal section of the speed cube; FIG. 2-view from the end; FIG. 3-the general scheme of its installation on a car and so on. N.j and FIG. 4 and 4 - details of the friction gear 4.
