Embodiment Construction

[0028] The technical solution of the present invention is further described in detail below, but the protection scope of the present invention is not limited to the following description.

[0029] Such as figure 1 As shown, the rotating system of the centrifuge is composed of 2 sets of hanging baskets 1, 2 tension belts 2, 1 set of rotating arm supports 5, 6 sets of positioning rings 7 and pin shafts, among which 2 tension belts 2 pass through the rotating arm supports 5 and 6 sets of positioning rings 7 are connected as a whole to form a jib. The parts installed on the hanging basket 1, the arm frame and the arm frame constitute a rotating arm. And 2 sets of hanging baskets 1 are suspended on the tension band 2 two ends by pin shafts. The transmission system 9 is fixed on the civil foundation, and the upper end of the main shaft 10 of the internal transmission system is fixedly connected with the arm support 5 through an expansion sleeve, so that the main shaft of the trans...

Abstract

The invention discloses a dynamic balance adjusting system of a centrifugal machine. A main shaft is provided with a central through hole on which an oil path can be laid. The oil path A and the oil path B are symmetrical, and both are started from an oil station, penetrate out of a central through hole of the main shaft, reach the arm support and are laid towards the two ends in the length direction of the arm support respectively, and when the ends of the arm support are reached, a pipeline is divided into two parts through a three-way pipe connector and then laid to central holes of the twotension belts respectively and fixed to the ends of the central holes of the tension belts. According to the adjusting system, the ground oil station is controlled, oil is conveyed to the rotary armthrough the rotary joint, and then a proper amount of oil is injected into the weight reduction center holes of the two tension belts at one end of the rotary arm, so that the purpose of dynamic balance adjustment is achieved. According to the invention, dynamic adjustment of large unbalanced force can be realized, and the space of the rotating arm is not occupied.

Description

technical field [0001] The invention relates to the field of centrifuges, in particular to a centrifugal motor balance adjustment system. Background technique [0002] Centrifuges are important equipment for geotechnical tests and environmental simulation tests. It generates a supergravity field of n times the acceleration of gravity through the high-speed rotating rotor system, compensates the self-weight stress loss of the model due to scaling, and produces n times the scaling effect at the model scale, n 2 times the time-lapse effect, n 3 Double the enhanced energy effect. [0003] In recent years, as the demand for centrifuge tests continues to increase, there is an urgent need to build centrifuges with larger scale and higher speed. The balance of the rotor system of a large-scale high-speed centrifuge will affect the stability, safety and service life of the centrifuge. For this reason, the rotor system of the centrifuge is generally provided with a balance adjustm...
