Mechanisms
Wheels odnorebordnye: Mechanisms of movement are called nodes, providing, as a rule, the horizontal movement of lifting machine (crane) or part (truck). The mechanisms of movement with the rails include bridge, gantry, cantilever, gantry, tower and railway cranes, bridge cranes. For track use the mechanisms of movement of crane wheels (drive, idle). All items mechanism of movement placed on the moving frame lifting machine (crane), or truck. Mechanisms of movement of crane wheels, in turn, move along double-girder paths. The mechanism of movement is composed of motor, gear drive transmission system and chassis (Crane wheels with bush and the shaft (drive, blank) Crane wheel undercarriage mechanism of movement of the crane is one of the main parts crane machines, in addition, has the property quickly deteriorate under heavy usage. There are different types of wheels such as wheel and dvuhrebordnoe odnorebordnoe.
Crane wheels are manufactured according to gost 28648-90 Billet crane wheels are manufactured so-called method of stamping or forging. In the manufacture of the mechanism of movement of steel is used categories 65G gost 14959-79. After machining Crane alloy heat-treated (sorbitizing). Crane wheel should have a hardness of track riding from 300 to 390NV. The depth of the hardened layer up to 30 mm depending on the diameter of the wheel. Sorbitizing necessary to achieve smooth transition from the hardened metal to non-hardened metal. Heat treatment process takes place in spreyernoy setup with constant control parameters (temperature and water pressure, cooling rate).
At the moment sorbitizing crane wheels is the best method of treatment has some significant advantages compared to bulk quenching and tempering T. C., such as high durability, cushioned hub, hardening depth of 30 mm. Wheels odnorebordnye: Mechanisms of movement are called nodes, providing, as a rule, the horizontal movement of lifting machine (crane) or part (truck). The mechanisms of movement having the track include bridge, gantry, cantilever, gantry, tower and rail cranes, overhead cranes. For track use the mechanisms of movement of crane wheels (drivers, idle). All elements of the mechanism of movement placed on the moving frame lifting machine (crane), or truck. Mechanisms of movement of crane wheels, in turn, move along double-girder paths. Mechanism movement consists of an electric motor, gear drive systems, transmissions and chassis (Crane wheels with bush and the shaft (drive, blank) Crane wheel undercarriage mechanism of movement of the crane is one of the main parts of crane machines, in addition, has the property deteriorate rapidly, with heavy usage. There are different types of wheels such as wheel and dvuhrebordnoe odnorebordnoe. Crane wheel manufactured according to gost 28648-90 Blanks crane wheels are manufactured so-called method of stamping or forging. In the manufacture of the mechanism of transport shall be steel categories 65G gost 14959-79. After mechanical handling crane wheels were heat-treated (sorbitizing). Crane wheel should have a hardness of track riding from 300 to 390NV. The depth of the hardened layer up to 30 mm depending on the diameter of the wheel. Sorbitizing needed for a smooth transition from the hardened metal to non-hardened. Heat treatment process takes place in spreyernoy setup with close control of parameters (temperature and water pressure, cooling rate). At the moment sorbitizing crane wheels is the most optimal method of treatment which has some great advantages in comparison with the bulk quenching and tempering T. C., such as high durability, cushioned hub, depth quenching to 30 mm.
