The input shaft is a very important part of the reducer. Everyone should have a deep feeling in the process of using it. In many cases, its input shaft will directly affect the work of the entire equipment.If you want to know more about the content of the reducer, you can take a look at the detailed introduction in the following article.
The structural shape of the shaft is not only affected by the load of the reducer, but also affected by the number, location, installation and fixing methods of the parts on the shaft, as well as the processing and assembly process of the shaft.Therefore, shafts with the same function have different structural shapes.The task of the design of the reducer shaft is to determine the effective configuration and all geometrical specifications of the shaft, taking into account the strength and bending stiffness.
The assembly line plan of the input shaft of the reducer is: bearings, elastic flat washers, non-skeleton rubber oil seals, and hoops are installed from the right end of the shaft to the left in succession, so that the order of the size of the shaft is arranged step by step.Because the input shaft is a rotating shaft, the diameter of the shaft is estimated step by step according to the standard of torsional and compressive strength, and the smaller diameter is taken.
From the specifications, structural properties, fixation, assembly and disassembly, support conditions, etc. of the shaft structure of the reducer shaft, it is confirmed that the reducer: the diameter of the first stage is 29 mm; the diameter of the second stage is 40 mm; The diameter of the 3 sections is 31 mm; the diameter of the 4 sections is 45 mm; the diameter of the 5 sections is 44 mm; the diameter of the 6 sections is 29 mm; the length of each shaft section depends on the width of the parts on the shaft and the fixed position of the parts Credibility.
The raw material of the reducer shaft must have any compressive strength and low sensitivity to stress; secondly, requirements such as bending stiffness, wear resistance, corrosion resistance, and processability should be considered, and the price and supply of the reducer should also be considered. condition of goods etc.From the design and calculation of the left and right shafts, it is speculated that: the shaft has high strength requirements, good plastic deformation and ductility requirements, and the reducer core strength requirements are not high. Considering the decision to choose 46 steel, steel that has been quenched and tempered The performance parameters are improved.
Roller bearings are standard support plate members commonly used in reducer construction.In operation, the roller bearing rotates the parts through the support plate of the turning body, so that the starting friction moment and the movement friction moment between the rotating parts are both small.Roller bearings adopt a large-scale systematic lean production method, and the cost is very low.The standardization level of roller bearings is high, and the dimensions, dimensional tolerances, raw materials, characteristics and instructions of roller bearings often have relative specifications.
