Cylindrical Open

GENERAL INFORMATION ABOUT THE REDUCTION GEARS TYPE "OPEN" AND THE EXPLANATION HOW TO WORK WITH THEM

1). The reduction gears of the "OPEN" type are in two main models with the cylindrical wheels and the kinetics that are widely use in heavy machine-building:
a) Model RGC ( the two-step reduction gear cylindrical) includes 6 sizes with the distance between the axes of the input and the output shaft, which are as follows: 250, 350, 400, 500, 650, 750 and 1000;
! The most important data when ordering are as follows:
(1) the distance between the axes of the input and the output shaft: 250-350-400-500-650-750 or 1000;
(2) gear ratio: 48.57-40.17-31.50-23.34-20.49-15.75-12.64-10.35 or 8.23
(3) mounting diagrams: 11-12-13-21-22-23-31-32 or 33 (according to the mounting diagrams).
! The proximate description of this type of the reduction gear with the distance between the axes of the input and the output shaft = 250 mm, gear ratio i = 31.5 and the mounting diagram 21 is RGC 250-31.5-21.
b) model RGCTS (Reduction gear cylindrical two-step) includes five sizes with the distance between the axes of the input and the secondary shaft, which are as follows: 100, 125, 160, 200 and 250.
! The most important data when ordering are as follows:
(1) the distance between the axes of the input and secondary shaft: 100-125-160-200 or 250;
(2) gear ratio: 6.3-7.1-8-9-10-11.2-12.5-14-16-18-20-22.4-25-28-31.5;
(3) mounting diagram: 11 - 12 - 13 - 21 - 22 - 23 - 31 - 32 or 33 (according to the mounting diagrams).
! The proximate description of this type of the reduction gear with the distances between the axes 100 mm (at low speed step), gear ratio i = 20 and the mounting diagram 21 is RGCCTS 100-20-21.
c) model RGCCTS (reduction gear, cone-cylindrical, three step) is a modified reduction gear RGCTS with the added cone gear at the input.
! The most important data when ordering are as follows:
(1) the distance between the input and the secondary shaft: 100-125-160-200 or 250;
(2) gear ratio: 25 - 31.5 - 40 - 50 - 63 - 80;
(3) mounting diagrams: 11-12-13-21-22-23-31-32-33-41-42 or 43 (according to the mounting diagrams)
! The proximate description of tis type of the reduction gear with the distance between the axes at the low speed step = 100 mm, gear ratio i = 25 and the mounting diagram is RGCCTS 100-25-41.
2) The output torque moment of the low speed shaft at the values given in tables can be calculated in the following way:
M1 = 9550 xN1/n1 [Nm] ;
M2 = M1.i.? [Nm];
,where N1 and n1 are the input power and the input revolutions (usually of the electric motor), M1 and m1 are the torque moment at the reduction gear input and output respectively, i is the gear ratio of the reduction gear, ? is the coefficient of efficiency of the reduction gear (usually ? = 0,96 ...0,97).
3). The overall and joining dimensions should correspond to figures and tables given below.
4). The firm reserves the right to change the construction of the geared-motor except changing the joining dimensions without notifying the clients.
5). When ordering the geared-motors you need please use the proximate descriptions given in p.1 a)., b). and c).
