Main parts of crank mechanisms
Main parts of crank mechanisms.Krivoshinu – a nut-gear mechanism serves to convert the reciprocating motion of the piston into a rotary motion. Crankshaft and piogo shaft (in steam engines or in internal crane engines). In machines such as piston pumps, compressors, the crank-and-rod mechanism serves to convert the rotational motion of the crank shaft into return. Piston movement The main parts of the crank mechanism (see Figure 61) are: crosshead, crosshead pin, connecting rod, crank 11.711 crankshaft, flywheels, or pulley Kreiikopof pivots the piston rod to the connecting rod. The crosshead pin is the axis of the hinge. When the crank mechanism is operated by a crank mechanism, the bolt clip moves back and forth in the guides. The connecting rod articulates the crosshead (and therefore the piston rod) with a crank or crankshaft. The neck of the columnar shaft 11 of the crosshead finger is the axis of the hinge joints at the right and left ends of the connecting rod. When working crooked. lli 11nno – connecting rod connecting rod makes a complex movement in the vertical plane. The complex movement of the connecting rod is composed of a cross-section of the crosshead finger of the reciprocating motion along the horizontal axis coinciding. with the piston rod axis. The right end of the connecting rod rotates the knees and the shaft The connecting rod part (see Figure 62), which is connected to the crosshead, is called the krei-kopf rozoaroi. The right connecting part of the connecting rod, which is connected to the crank or crankshaft, is called the crank hole in the crankcase and crank head of the connecting rod into which the bushings of the antifriction material are pressed in, are called connecting rods, “the rocking crank or crankshaft transmits rotation to the flywheel Crankshaft bearings.
cranked or crankshaft, bearing the name of the main bearings. The flywheel, having considerable weight and great inertia during rotation, is a regulator of active and passive resistors. and makes the operation of the mechanism smoother. In machines such as reciprocating pumps, compressors, the flywheel sometimes performs pulley functions, i. E. serves for the transfer of motion through the belt from the drive motor. In the crank-connecting mechanisms used in internal combustion engines, one end of the connecting rod is pivotally connected directly to the body of the piston. The connection is made by tides in the internal cavity of the cast cylinder and the finger that is inserted into these tides and passes through the hole at the end of the connecting rod. This end of the connecting rod is called the piston section
