Abstract

A swash-plate-end bearing for the motor shaft in a high pressure cleaning appliance which includes a motor and a reciprocating pump driven thereby, wherein the pistons of said pump rest resiliently on a swash plate driven by the motor whose shaft is rotatably mounted at each end whilst being connected at one end in non-rotatable manner to the swash plate, and which also includes at the swash plate end, a roller bearing having two concentric bearing rings, whereby the outer bearing ring is held in an end plate of the motor whilst the inner bearing ring surrounds the motor shaft, in such a manner as to simplify the operation of assembling the motor shaft and the bearing and to make it as independent as possible from unavoidable manufacturing tolerances, it is proposed that the inner bearing ring should surround the motor shaft in floating manner.
