Description
Technical field
The utility model relates to aeroengine retarder field, is a kind of novel transmission system load balancing structure.
Background technique
Aeroengine retarder is generally input, exports coaxial transmission, because its structure has symmetry properties, therefore the normal parallel connection transmission mode adopting be uniformly distributed along the circumference several planetary pinion or intermediate gear, namely by branch, input power is shunted in transmission process, and then by and truck system carry out power merging, if load equalization between drive branch, then transmission system functional reliability is high, and this structure just can have the advantage that high reliability, compact structure, volume mass are little, meet high-speed overload working condition requirement.In the reducer structure of current novel aircrafts, the drive mechanism of this " point turn round-and car " power dividing and merging is the structure comparatively commonly used.Due to " point turn round-and car " drive mechanism, system itself has the feature of power closed loop.But owing to inevitably there is the impact of the factor such as resiliently deformable and temperature of foozle, alignment error, component, desirable load equalization is difficult to realize, between the drive branch caused thus, load is unbalanced, cannot realize this structure and bring various advantage.
Summary of the invention
The purpose of this utility model improves engine retarder power dividing inequality to carry phenomenon, improves function of the engine, reduce engine weight, form a kind of novel load balancing structure.
Concrete technological scheme of the present utility model is, transmission system load balancing structure comprises input gear axle, output gear shaft, spline switching cover, roller bearing, described input gear axle one end is provided with herringbone tooth and engages with the herringbone tooth of power intake, the other end is provided with external splines, output gear shaft is hollow elastic axis, one end is provided with internal spline and is arranged on one end input gear axle not being arranged herringbone tooth by spline switching cover, described spline switching puts and is provided with internal spline and outer flower-key, engage with the external splines of input gear axle and the internal spline of output gear shaft respectively, the external diameter of described output gear shaft is provided with tooth and engages with clutch end, output gear shaft is arranged on reduction case by roller bearing.
The utility model comprises herringbone gear, axial float roller bearing, hollow elastic axis and spline switching cover.When a certain road gear pair resultant error is bigger than normal, transmission equal load system will adjust according to self structure:
A. driving gear is herringbone gear, and, identical a pair helical gear of all the other parameters contrary by helix angle forms, and this structure can axial error in Reasonable adjustment transmission process, ensures the centering of gears meshing;
B. drive mechanism middle (center) bearing adopts roller bearing, due to its axial float, can meet the requirement of gears meshing adjustment;
C. elastic axis is thin-walled elastic part, is overcome the error produced in transmission process by its torsional deflection, and the system that realizes each road uniform load distributes.
D. spline housing transmitting torque in the course of the work, retrains floating roller simultaneously.During spline transmitting torque, interior external splines produces frictional force, and floating roller is subject to the acting in conjunction of gear mesh force, spline switching cover support force and frictional force, thus reaches adjustment floating roller position or make elastic axis that suitably distortion occur, and reaches power and all carries transmission effect.
The utility model, by rational structural design, have adjusted the inequality caused by various error and carries phenomenon, ensures retarder transmission stability and high reliability, due to its compact structure, for motor loss of weight also provides effective guarantee.
Accompanying drawing explanation
Fig. 1 is that the utility model retarder all carries regulating device schematic diagram.
