Abstract
Axial adjustment method for precessional transmissions includes compensation error calculation, determination compensator groups, achieved in the form of base and auxiliary rings. The compensator has on the base ring axial canals in which can be placed clamping bolts but the auxiliary ring has axial holes for the screws. The auxiliary ring is formed from increasing sectors - the distance between auxiliary ring stairs and front side of body, from decreasing sectors - the distance between base ring and bottom place, and the closure element - the clearance between gear body and the front surface of the base ring. According to the method of group interchangeability is determined the deviation value of the upper and lower group tolerance and the clearance between lid and body. Then rotating one of the rings is ensured the dimension of the compensator which must match to compensation clearance value and then the compensator is adjusted to required value.
Highlights
This method of adjustment of axial movements without thread can be used to adjust clearance in gear, especially in gearboxes
From [1] is known the adjustment process of axial clearance, in which from chains of dimensions are determined the amount of compensation, the number of fixed compensators steps and their size
In assembling process is measured the axial clearance between front surface of the lid and the bearing, is chosen compensation gaskets size and is installed on the closure element of the chain
Summary
This method of adjustment of axial movements without thread can be used to adjust clearance in gear, especially in gearboxes. In assembling process is measured the axial clearance between front surface of the lid and the bearing, is chosen compensation gaskets size and is installed on the closure element of the chain. The disadvantage of this method of clearance compensation is high workmanship of assembling; because of the collecting complexity for the required compensation rings and the execution complexity of the rings (less than 0.1mm). This method has a disadvantage namely cannot be used to adjust conic gear. The purpose of this method is to decrease the assembling costs of the frontal surfaces of machines nodes, which contain precessional gearing, and to increase of adjustment precision for axial clearance
