Abstract

The invention relates to a shield main drive sealing element performance comprehensive simulation test bench which comprises a shell and rotating shaft mechanisms located on the two sides of the shell in the X-axis direction, the shell is installed on a vibration table below, and each rotating shaft mechanism comprises a supporting frame, a gland, a rotary support and a rotating shaft. A hydraulic motor is arranged at the top of the supporting frame through a driving support in the X-axis direction, a driving shaft of the hydraulic motor is in driving connection with a rotating shaft on the inner side, the rotating shaft is connected with a shell on the inner side, a rotary support is arranged at the joint of the rotating shaft and the shell, and the gland is arranged on the rotating shaft on the outer side of the rotary support. The shield main drive sealing element performance comprehensive simulation test bench is high in comprehensive performance, can comprehensively test various performances of a sealing element at a time, is simple in test steps, and can improve the test efficiency.

Description

technical field [0001] The invention relates to the related technical field of seal testing, in particular to a performance comprehensive simulation test bench for shield main drive seals. Background technique [0002] my country's infrastructure construction has entered the stage of large-scale construction at the beginning of the 21st century. In the next five years, my country's road, railway, water conservancy and energy projects will require more than 120 large-scale roadheaders, with a total price of more than 30 billion yuan. The main drive seals of domestic roadheaders have successfully replaced imported products to support small and medium-sized roadheaders, but in terms of large roadheaders, domestic research on sealing technology is still at a low level, especially for large-diameter roadheaders with high reliability and service life requirements. The drive seal is also completely dependent on imports. If large-diameter tunnel boring machine seals can be produce...
