Abstract
PURPOSE: To reduce the load of thrust on the bearing part of a driving shaft and increase the durability thereof by a method wherein the pump-discharged oil is led to the side of the driving shaft through the passage piercing a push rod and the hydraulic force thus obtained is made to act so as to offset the force of thrust.
CONSTITUTION: The pump-discharged oil is led to the side of a driving shaft 10A through a passage 40 piercing a push rod 22A, while, based on the supply of this pressure oil, an auxiliary piston 47 pressing the driving shaft 10A in the axial direction by the counterforce therefrom is provided in a housing boss part. When a part of the discharged oil is led into a cylinder chamber 48 through the push rod 22A with the pumping action of a pump A, the auxiliary piston 47 is pushed out by the pressure of this oil, pressing strongly a disc 49. This generates strong hydraulic counterforce in a piston case 46, whereby the driving shaft 10A is pressed, through the intermediary of a staged part 45, in the direction countering the force of thrust caused by the operation of a piston part 7A. Accordingly, the force of thrust applied to a taper roller bearing 14A is reduced to a great degree and thereby the load on the bearing is weakened and the durability thereof is increased.
