Heat dispersion disk sheet clearance support system for disk type heat dispersion machine

Abstract

The invention provides a heat dispersion disk sheet clearance support system for a disk type heat dispersion machine. A piston rod is hollow; a transmission shaft can penetrate the inner cavity of the piston rod; a bearing mounting position is arranged at the rear end of the inner cavity of the piston rod; the interior of the cylinder sleeve is convex, so that the cylinder sleeve is divided into a front work cavity and a back work cavity of which the inner diameters are the same; the inner diameter of the front end of the cylinder sleeve equals to the outer diameter of the protrusion at the front end of the piston rod; the inner concave part in the middle of the piston rod and the inner convex part of the cylinder sleeve work in a matched manner; the length of the inner concave part of the piston rod is larger than that of the inner convex part of the cylinder sleeve; a distance fixing sleeve for positioning the stroke of the piston rod is arranged between the piston rod and the rear end of the cylinder sleeve in a sleeving manner. The heat dispersion disk sheet clearance support system adopts a double-acting hydraulic cylinder with the hollow piston rod instead of two hydraulic cylinders, so as to effectively solve the problem of driving the two hydraulic cylinders synchronously; the two hydraulic cylinders are driven to be synchronous stiffly while the single hydraulic cylinder is driven to be synchronous completely.

Description

technical field [0001] The invention relates to a disc type heat dispersing machine, in particular to a heat dispersing disc gap support system of the disc type heat dispersing machine. Background technique [0002] The heat dispersion disk gap support system of the existing disk type heat dispersion machine is composed of 2 hydraulic cylinders, and the two hydraulic cylinders are used to synchronously drive the moving disk to move, and the two hydraulic cylinders are used to synchronously drive the moving disk of the heat dispersion disk. Since the dual hydraulic cylinders are rigidly synchronized, interference and instability are prone to occur. Once the wear is unbalanced, the interference and imbalance will be further aggravated. Simultaneously owing to adopt double hydraulic cylinder to drive, then there is the oil leakage point that seal failure easily occurs in the bearing seat between two power transmission shafts.

Problems solved by technology

[0002]The heat dispersion disk gap support system of the existing disk heat dispersion machine is composed of 2 hydraulic cylinders, and the two hydraulic cylinders are used to drive the moving disk synchronously. Two hydraulic cylinders are used to synchronously drive the moving disc of the heat dispersion disc. Since the dual hydraulic cylinders are a kind of rigid synchronization, interference and instability are prone to occur. Once the wear is unbalanced, the interference and imbalance will be further aggravated

At the same time, due to the use of dual hydraulic cylinders for driving, there is an oil leakage point that is prone to seal failure in the bearing seat between the two transmission shafts
