Abstract

A kind of vibration wheel used in vibration pressing machine includes an outer roller, an outer separator plate and a hydraulic vibration exciter, etc. It features that an inner roller is designed in the outer roller; a saddle support and a hydraulic cylinder of the vibration exciter with overhanging pole are installed in the inner roller; two half shafts are connected to the saddle support as an integrated part; inner and outer rollers are put on two half shafts by the inner and outer separator plates. The invention using the hydraulic vibration exciter as vibration source can produce transnational vibration at any directions, moreover stepless frequency modulation and amplitude modulation can be realized respectively.

Description

technical field [0001] The invention is mainly used for vibrating rolling machines, especially for vibrating road rollers. Background technique [0002] Currently used vibratory rollers all use internal vibrating vibrating wheels. A vibrating shaft is installed in the vibrating wheel, and a group of eccentric blocks are installed on the shaft to form an inertial vibrator. When the vibratory roller is working, the hydraulic motor drives the eccentric block to rotate at a high speed to generate centrifugal force, and the vibrating wheel generates circular vibration under the action of this centrifugal force (see "Construction Machinery" No. 9, 2000, page 42 for details). This kind of vibrating wheel produces inertial vibration by means of an inertial vibrator. Without changing the structural size of the vibrator, its vibration frequency and amplitude cannot be adjusted independently, nor can different vibration frequencies and amplitudes be combined arbitrarily. Therefore, w...
