Axially movable hydrostatic bearing device

Abstract

The invention discloses an axially movable static pressure bearing device, which is fixed by a shaft, a flat key, a saw blade positioning ring, a left end cover, a static pressure thrust bearing, a right end cover, a static pressure bearing seat, a saw blade, and a saw blade rings and seals. The saw blade fixing ring is fixed on the right side of the saw blade positioning ring with countersunk screws, and the static pressure bearing is matched with the groove clearance on the saw blade positioning ring through two semicircular right end covers; the static pressure bearing and the right end cover are through countersunk screws Connection, the outer side of the hydrostatic bearing cooperates with the bearing seat, and is sealed with a sealing ring at the contact surface; the inner side of the hydrostatic bearing has a pressure oil chamber and an oil return groove, and cooperates with the positioning ring of the saw blade; the left end cover is connected with the pin of the hydrostatic bearing , and the bearing seat is connected by countersunk screws; the inner groove of the saw blade positioning ring cooperates with the flat key on the shaft, which can not only rotate synchronously with the shaft, but also move axially along the flat key. It can realize the axial movement of the saw blade when it rotates, and solves the problems of large error and low efficiency of manual adjustment and shutdown adjustment.

Description

technical field [0001] The invention relates to an auxiliary device for axial movement, in particular to a hydrostatic bearing device capable of axially moving a rotary saw blade. Background technique [0002] In the sawing process, it is often necessary to adjust the position of the saw blade to meet different sawing width requirements. Manual adjustment is time-consuming and labor-intensive and reduces production efficiency; downtime adjustment has adverse effects on the machine itself and production. It is best to adopt automatic saw blade adjustment, but how to realize the saw blade to rotate and move in the axial direction is a new technical difficulty. If rolling bearings are used, they have the disadvantages of large size, large vibration, high noise, easy wear and poor environmental adaptability, and require regular maintenance, resulting in high overall costs. [0003] The invention adopts the static pressure thrust bearing, which has the characteristics of good b...
