What does it mean for a speed reducer to have a stringy shaft? Occasionally, I hear my friends say that their speed reducer has the phenomenon of crosstalk. Reducer crosstalk refers to the phenomenon that the input shaft or output shaft moves in the axial direction during the operation of the reducer. And this offset has exceeded the allowable range of the original design of the reducer, which will produce unstable equipment, noise, parts wear and tear to speed up the problem. So what exactly are the reasons for the reducer string axis?
Broken Gear
It is due to broken gear so that the input shaft loses axial constraints and crosstalk occurs.
Gear and shaft fastening is not firmly
Is the intermediate shaft of the slave gear and shaft fastening is not firmly caused. In the actual transmission, often due to the follower gear and the intermediate shaft between the amount of interference is not enough, the follower gear relative to the intermediate shaft to produce axial crosstalk, and then make the input shaft axial crosstalk. Therefore, insufficient interference is the main reason for the reduction gear crosstalk.
Steering of the reducer
The steering of the reducer also has a certain impactsteering of the speed reducer.
Incorrect assembly
Improperly mounted bearings
Insufficient bearing preload and other related mounting problems, resulting in large axial clearance
The coupling is not centrally aligned
It is not fully centrally aligned, resulting in additional axial force and triggering axial displacement
Wear and tear of parts
Damaged bearings
When the bearings are worn out, the ability to hold axial positioning decreases, triggering the crossthreading
Wear and tear of gears
Wear and tear of gears will change the original design clearance, increasing axial force and resulting in axial displacement. axial displacement.
Insufficient lubrication
Poor quality lubricant may be used, resulting in excessive friction
Uneven thermal expansion
The working temperature affects the clearance between the bearings and the housing, which is too large and leads to crosshafting. However, this problem will not be found in the normal use of temperature environment, unless the reducer is not used for a long time in the specified temperature and humidity environment.
In short, there are many reasons that lead to reducer crosstalk, the above are some of the reasons summarized by JZC that lead to reducer crosstalk.
