It is customary to call gearboxes (gear worm or hydraulic), the purpose of which is to change the angular velocities and torques. Devices that have the functionality of changing the angular speed are also called a gearbox, a continuously variable gearbox is a variator.
In general, gearboxes are classified according to several criteria:
- type of transmission (distinguish between worm gear, gear or their variations);
- type of gears (worms, bevel and cylindrical);
- the location of the input and output shafts (vertical and horizontal);
- number of steps (one, two and three steps).
In a number of spheres of the national economy, the 1Ch-63 reducer (single-stage worm gear for general machine-building purposes, universal) has become widespread, which is necessary for the appropriate conversion of rotation frequency and torque. The device changes the angular speed and torque of the motor (by means of a worm gear), inside which it is located. The gearbox of the above brand is actively used in Voronezh , Moscow, Rostov-on-Don, a number of other regions of the country.
Long-term operation of the transmitting device is only possible if the special conditions of its use are observed:
- outdoor air temperature in the range from -40C to + 50C;
- external environment - non-aggressive, non-explosive;
- the gearbox is subject to constant and variable loads, the same direction and with periodic reversal;
- compliance with the requirements of GOST 15150 (for placement categories from 1 to 3 - version U and T, for placement category 4 - version UHL).
The rotation of the shafts during operation of the gearbox can be carried out in any direction, without any preference.
What you need to know about the designation of the worm-type gearbox? 1CH in the name denotes the type of device, numbers 63 - the center distance.
An overview of the 1Ch-63 gearbox will not be complete without specifying its basic technical characteristics. It is about:
- rated torque (on the output shaft, in N * m) - 160, 140, 132, 160, 140,132, 200, 180, 150, 112, 106;
- gear ratio (nominal) - 8, 10, 12.5, 16, 20, 25, 31.5, 40, 50, 63, 80;
- efficiency (in%) - 90, 89, 88, 86, 84, 80, 76, 75, 69, 64, 60;
- corrected sound power level (in dB) - 82;
- permissible radial load on the output shaft (in N) - 3200;
- rotation speed (in rpm) - up to 1500;
- weight (kg) - 16.
