Problems solved by technology

Therefore, the outer surface of the eccentric shaft and the inner surface of the eccentric sleeve are cylindrical eccentric mechanisms, which will inevitably affect the vibration accuracy of the crystallizer and cause wear due to excessive clearance, or it is difficult to adjust the eccentric distance due to too small clearance.

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] figure 1 The structure of the eccentric shaft 9 is given. The cylindrical surface 1 is connected to the reducer through a coupling. Bearings are installed on the cylindrical surfaces 2 and 4. The bearings are connected to the base to support and fix the eccentric mechanism. The matching part of the eccentric shaft 9 is composed of The large cylindrical surface 5, the circular table surface 6 and the small cylindrical surface 7 are connected in sequence. The diameters of the end faces of the convoluted surfaces at the joints are equal. The fastening and disassembly of the sleeve 12 is called the rotation axis of the eccentric shaft 9 when it is working, that is, the axis of the shaft head of the eccentric shaft 9 is the main axis, and the large cylindrical surface 5 of the eccentric shaft, the circular table surface 6, the small cylindrical surface 7 a...

Abstract

The invention discloses a crystallizer-oscillated eccentric mechanism without a radial clearance, and relates to continuous casting equipment. The eccentric mechanism is characterized in that a matching part of an eccentric shaft and an eccentric sleeve is formed by connecting large cylindrical surfaces, circular table surfaces and small cylindrical surfaces; two disc bodies with the equal external diameter are arranged on the eccentric shaft and the eccentric sleeve respectively and are connected with the large cylindrical surfaces of the eccentric shaft and the eccentric sleeve respectively; a key groove is formed in the circumference of each disc body respectively; keys are mounted in the aligned key grooves; and the two disc bodies are fastened together through a clamping ring. According to the invention, the circular table surfaces are matched without a clearance, so that the radial displacement of the eccentric shaft and the eccentric sleeve is avoided; and therefore the defects of radial oscillation and radial abrasion generated between the eccentric shaft and the eccentric sleeve due to the fact that a mounting clearance is preformed on the existing eccentric mechanism is overcome. In addition, the clearance matching is adopted by the cylindrical surfaces of the eccentric shaft and the eccentric sleeve, so that the eccentric mechanism is mounted and disassembled simply and easily, and the eccentric distance of the eccentric mechanism is also regulated simply and easily. The eccentric mechanism provided by the invention has the advantages of simple structure, long service life, stability in running and high oscillation precision.

Description

technical field [0001] The invention relates to continuous steel casting equipment, in particular to a vibration eccentric mechanism of a crystallizer of a continuous casting machine. Background technique [0002] In continuous casting production, in order to make the steel billet be pulled out from the mold smoothly, the mold needs to vibrate up and down. The existing mechanical vibration generating device is generally composed of a motor, a reducer or a variable speed reducer, an eccentric mechanism and a connecting rod mechanism. The fit and fixation of components is the key and difficult point in the process of installation, operation and adjustment of eccentric distance of eccentric mechanism. The continuous casting production process requires the amplitude of the vibration mechanism to be adjusted according to different steel types and casting speeds. Therefore, the relative position of the eccentric shaft and the eccentric sleeve must be adjusted to control the eccen...
