Change, so as to cause gear life to meet to require, or even rapid failure.Playing the advantage of roller gear point torsion transmission system is
Hypothetical, this premise is exactly the load mean allocation of necessary Shi Liangge branches.
At present, the torsion method that transmission system carries is divided mainly to have following several：A) carried using equalizer bar, using the party
Method carries, it is necessary to and it is that one-level helical gear and one-level spur gear are used cooperatively, but helical gear use can increase axial force, in reality
The requirement to system supporting is also improved while now load.This method realizes that the process carried can cause duplicate gear frequency simultaneously
Numerous axial direction floating, adds between cog fretting wear and the vibration of system.And equalizer bar itself is complicated, it uses increasing
Add the weight of system, reduced the reliability of system, slacken the Inherent advantage that roller gear point turns round transmission system.B) rely on
Manufacture with installation accuracy to realize, the method increase manufacture and the maintenance cost of gear, and each gear is required for carrying out only
One axial modification, causes gear not have interchangeability.C) use flexible member load mode, this method include flexible shaft and
Flexible gear.For flexible gear, fluorubber element is added usually on former, this use condition to system has more
Limitation requirement, also limit the service life of system；For flexible shaft, due to being usually to be connected with spline, this is for flower
The number of teeth of key and the number of teeth of gear require, and not easy to install.
