Special crane gearboxes type VK

Special crane (cylindrical three-stage) gear type VK are designed for use the drive mechanisms for the movement of cranes. The gearboxes are designed for operation in the macro-regions with moderate (climatic version) and dry and wet tropical (T) climate, location category 2 according to GOST 15150. Cylindrical vertical crane gearboxes type VC is designed for use in the following conditions:

· Rotation of the shaft in both directions;

· Ambient temperature -40°C to +50°C;

· Non-aggressive environment, moderate dustiness and humidity;

· The rotation speed of the fast shaft is not more than 1000 rpm

The estimated coefficient efficiency of the gear - 0,91. The cylindrical vertical crane special type VK mechanisms for movement of cranes

Cylindrical the gearbox is perhaps one of the most popular types of gearboxes in mechanical engineering. The units are mainly used in machinery, which has intermittent loading conditions. Gears are used to transmit rotational movement between coaxial or parallel shafts. Significant the advantage of such mechanisms is the high efficiency and durability.

The purpose

Special crane the gearboxes of the type VK-350, VK-475, VK-550 is a cylindrical, three-stage units that are designed to work in drives mechanisms of movement of cranes. Operation of gearboxes possible in macroclimatic areas with moderate (climatic version) and dry and humid tropical (climatic version T) climate, location category 2 according to GOST 15150. The estimated efficiency of the gear - 0,91.

Conditions of use:

• rotation of the shaft in both sides;
• ambient temperature -40°C to +50°C;
• the rotation speed of the fast shaft should not exceed 1000 rpm./minutes;
• non-aggressive environment, moderate dustiness and humidity.
