SU10620A1 - Friction attachment to a safe kickback handle - Google Patents

Description

Handle g n stitched to her dog S dizhuts together with the shaft ir. The part of the liner, supported by the nut g, is mocked freely) to rotate in the holder d attached to the frame of the body by screws, and is rotated by the handle K. a slit as shown in FIG. 2. The sleeve e can freely rotate in the direction of the starting movement and stalls during rotation and direct reverse start. The stoppage is achieved by reverse free rotation with the help of free lower rollers.

The sleeve e is provided (Fig. 2) with a small sleeve, the roller of which can move. The latter enters, from the OJIHOH side, into the spur of the sleeve, and, on the other hand, protrudes through the longitudinal slot of the ring-shaped protrusion, enters the grooves of the / -value O. form a resultant force, under the influence of which the sleeve e cannot be turned by the force of the gripping roller i, but begins to play the role of a support rigidly connecting the shaft a, the annular projection k and the sleeve e. By reverse rotation of the intermediate shaft a, under, the action premature sun yshki, the force distribution is disturbed, and the pickup roller / vdvigaets a recess ° It sleeve ostanovivsheys vsled-, stvis clamping rollers / ioient This stops forced stseplsiie s between the handle and the intermediate shaft or on the motor shaft. .

If, due to a premature outburst, the motor shaft z and the intermediate shaft o begin to move in the direction opposite to the starting direction, then by lowering the pickup roller / into the recess L. four),. handle g and driven by it into the mouth of the mouth 6 | and 6s almost instantly lose their grip to the shaft l. In the absence of a friction cone t, pressed by the spring and to the conical groove w, it is possible to move the handle f in the starting direction without resistance under pressure from it by the person starting the engine, as a result of which the person could be exposed to danger. But since the handle g can move further only by overcoming friction between the shaft and shaft taper t and the parts 1 and bz forcibly connected with the handle ff, the handle g has to overcome a rather large resistance. | ro move without resistance to, from the ground.

Subject

The friction device is safe for a kickback handle with an intermediate: shaft, characterized by the use of a key with an intermediate shaft and an axially movable friction cone t pressed by a spring n to the socket a. Part 2, forcibly connected when starting the engine with jr.
