What are the maintenance and upkeep methods for TPS200-20-1F planar enveloping toroidal worm gear reducer

TPS 200-20-1F belongs to the TP series planar enveloping toroidal worm gear reducer. Based on the industry standard JB/T9051-1999 and the general parameter rules of this series of reducers, the model meaning is first disassembled, and then its detailed technical parameters are organized as follows:

1、 Analysis of Model Meaning

TPS: represents the planar enveloping toroidal worm gear reducer on the side of the worm wheel

200: represents a center distance of 200mm for the reducer

20: The representative nominal transmission ratio is 20

1: Representing the first assembly type (with slight differences in the definition of assembly types among different manufacturers, often corresponding to basic assembly differences such as installation hole positions and shaft extension directions)

F: Representative with fan cooling device, used for auxiliary heat dissipation when the ambient temperature exceeds 40 ℃

2、 Core technical parameters

Basic transmission parameters: The transmission type is flat primary enveloping worm gear transmission; The nominal transmission ratio is 20, and the direction of the worm spiral is right-handed; Input shaft speed ≤ 1500r/min. When the input shaft speed is 1500r/min, the rated input power is about 12.81kW, corresponding to an output speed of about 75r/min (obtained by dividing 1500r/min by 20)

Center distance and structural dimensions: Center distance is 200mm; the shell is mostly made of cast iron or cast steel material, with a compact overall structure. Referring to the same series of dimensions, its length is about 580mm, width is about 405mm, and height is about 335mm (slight deviation from different manufacturers)

Core component material: Worm gears are commonly made of 45 # steel, 40Cr or 42CrMo, and after nitriding treatment, the tooth surface hardness can reach HRC58 or above; Worm gears are often made of wear-resistant tin bronze; The bearings are selected from SKF and other brands, and the oil seals are imported high-temperature resistant oil seals

Load capacity: Referring to the general parameters of the TPS 200 series, its allowable torque is about 4200 N · m (specific needs to be combined with actual working conditions and manufacturer calibration); The contact area of the tooth surface can reach over 70%, with strong meshing stability and better load-bearing capacity than ordinary worm gear reducers

3、 Working conditions and adaptation requirements

The working environment temperature range is -40 ℃~40 ℃; When the ambient temperature is below 0 ℃, the lubricating oil should be heated to above 0 ℃ or low freezing point lubricating oil should be selected before starting;

Lubricating oil should be selected according to the ambient temperature. For normal working conditions, medium load industrial gear oil can be used, while for high temperature or heavy load working conditions, corresponding specialized lubricating oil should be matched.
