Gearbox CDN

THE CYLINDRICAL TWO-STAGE CDN

Gearbox CDN

two used different drives machines and mechanisms for changes in torque and rotational speed. Can to be made with the end of the output shaft in the form of a gear coupling.

The operating conditions of the cylindrical two-stage horizontal, with the transmission Novikov, General engineering use CDN-630 and CDN-710:
- work lasting up to 24 hours. a day or with periodic stops;
- work in continuous and intermittent modes, i.e., when variables loads with periodic stops, the load in one direction and reversible;
- speed high-speed shaft is not more than 1500 rpm;
the rotation of the shaft in either direction;
- non-aggressive environment, the atmosphere of the types I and II according to GOST 15150 with dusty air is not more than 10 mg/m3;
climatic version - U1, U2, UZ, T1, T2, TK according to GOST 15150.

Basic technical data.
Technical characteristics of the gears CDN when non-reversing mode shown in the tables.
When the reverse mode of operation and in the case of gear mechanisms increased responsibility torque on the low speed shaft should be reduced by 25%.
In the operation of the gearbox in the intermittent mode of operation without stops over 30 minutes mode be considered continuous.
Torque on the low speed shaft in the intermittent operation mode must be lowered when the number of starts "and" per hour, respectively: a - 16%; a - 20%; a - 30%.
Gearboxes CDN allow short-term overload, twice the tables and during starts and stops the engine if the number of cycles of loading speed of the shaft for the duration of the overload is not exceeds h during the entire service life of the gearbox. Permissible frequency of cycles per unit of time should be no more than two in hour in continuous operation.
For dvukhkontsevaya performances shafts values of admissible radial cantilever loads should be reduced by 50%.
Tolerance gear ratio of the gearbox CDN - 4%.
