Abstract
The safety gear is constituted by a sleeve 1 which is fitted to a chain drive 2 coaxially herewith. The tubular sleeve has diametrical recesses 3 in which a piston 4 is displaceable to and fro. It is nevertheless detained in the groove by means of a bolt 6 which is screwed into the piston. The chain drive 2 is fitted vertically so that when the pinion gear rotates upon movement of the lift, for example, the piston 4 joins in the rotation but falls throughout under gravitational effect to assume its lowermost position. This applies as long as the chain drive moves at a moderate speed. Should the speed be increased, then the centrifugal force acting upon the piston will detain this in its projecting position so that it hits against the stop 7 which is arranged over the chain drive. <IMAGE>

SU362959A1 (en) | AUTOMATIC EDGE VEHICLE VARIATOR OF SPEED1 The invention relates to the field of mechanical engineering and can be used in machine drives that require constant angular velocity of the driven shaft while reducing the speed of the drive motor. centrifugal weights for automatic adjustment of the speed of the driven shaft. The proposed variator is characterized in that the centrifugal weights are equipped with tymi gears mounted on the shafts located in the hub is fixed conical disc. The hub of the movable conical disk is equipped with toothed racks, interacting with them with gears, and inside this hub there is a hydraulic cylinder with a piston, provided with holes and rigidly mounted 20 on the shaft. The automatic V-rim speed variator contains a leading / and driven 2 shafts, fixed 3 and movable spring-loaded 4 tapered discs, a device with centrifugal weights 5, equipped with gear gears 6, which are mounted on axles 7 located in the hub of one fixed tapered disc 3. The hub of the movable di Ska 4 is equipped with toothed rails 8 that interact with gears 6, and inside this hub there is a hydraulic cylinder with a piston 9 equipped with holes and fixed on shaft 2. The described speed variator works as follows. At the nominal angular velocity of the drive shaft / weights 5 are in a horizontal position, while the diameter of the belt 10 of the driven shaft 2 is minimal. As the angular velocity of the drive shaft increases, the speed of the driven shaft increases. The weights 5 under the action of centrifugal inertial forces rotate about their axes and force the movable disk 4 to move, thereby increasing the diameter clinging to the V-belt 10 and reducing the angular velocity of the driven shaft 2. | |
