PS200-20-1F belongs to the TP series planar enveloping toroidal worm reducer. Based on the JB/T9051-1999 industry standard and the general parameter rules of this series of reducers, we first disassemble the meaning of the model and then organize its detailed technical parameters, as follows:
1. Analysis of model meaning
TPS: represents a planar enveloping toroidal worm reducer with the worm on the side of the worm gear
200: means the center distance of the reducer is 200mm
20: represents the nominal transmission ratio of 20
1: Represents the first assembly type (different manufacturers have slightly different definitions of assembly types, mostly corresponding to basic assembly differences such as mounting hole positions and shaft extension directions)
F: stands for fan cooling device, used for auxiliary heat dissipation when the ambient temperature exceeds 40°C.
2. Core technical parameters
Basic transmission parameters: The transmission type is plane primary envelope worm transmission; the nominal transmission ratio is 20, the worm spiral direction is right-handed; the input shaft speed is ≤1500r/min. When the input shaft speed is 1500r/min, the rated input power is about 12.81kW, and the corresponding output speed is about 75r/min (derived from 1500r/min÷20)
Center distance and structural size: center distance 200mm; the shell is mostly made of cast iron or cast steel, and the overall structure is compact. Refer to the dimensions of the same series, the length is about 580mm, the width is about 405mm, and the height is about 335mm (different manufacturers have slight deviations)
Core component material: worms are commonly made of 45# steel, 40Cr or 42CrMo. After nitriding treatment, the tooth surface hardness can reach above HRC58; worm gears are mostly made of wear-resistant tin bronze; bearings are made of SKF and other brands, and oil seals are imported high-temperature resistant oil seals.
Loading capacity: Refer to the general parameters of the TPS200 series, the allowable torque is about 4200N·m (the specific needs to be combined with the actual working conditions and manufacturer calibration); the tooth surface contact area can reach more than 70%, the meshing stability is strong, and the load-bearing capacity is better than that of ordinary worm reducers.
3. Working conditions and adaptation requirements
The working environment temperature range is - 40℃~40℃; when the ambient temperature is lower than 0℃, the lubricating oil needs to be heated to above 0℃ before starting, or low freezing point lubricating oil must be selected;
Lubricating oil needs to be selected according to the ambient temperature. Medium-load industrial gear oil can be used for normal working conditions. Corresponding special lubricating oil must be matched for high-temperature or heavy-loading conditions.
