Problems solved by technology

This method of using circulating cooling water to flow in the grid to take away heat has a small heat dissipation area, short cooling water flow channel, unsatisfactory heat dissipation effect, and unreliable sealing structure, which may easily cause water leakage or even oil-water mixing, which will affect the drive gearbox. Other components of the shield machine will cause premature failure of the main cutterhead drive gearbox of the shield machine

Embodiment Construction

[0028] Combine below Figure 1 to Figure 4 Embodiments of the present invention are described in detail.

[0029] Drive the cooler in the gear box. The cooler has a cylindrical structure with an open top. The top and bottom of the cooler are respectively provided with an annular sealing plate 1 and a sealing plate 2. The cooler is also provided with an annular The interlayer 3, the interlayer 3 is arranged between the sealing plate one 1 and the sealing plate two 2, the interlayer 3 is axially separated from the sealing plate one 1 and the sealing plate two 2, and the interlayer 3 is provided with A water gap 31, the water gap 31 of the adjacent interlayer 3 is staggered by a certain angle along the circumferential direction of the interlayer 3.

[0030] Such as figure 1 As shown in the cooler, it is installed in the driving gearbox, sealing plate 1 and sealing plate 2 are used to seal the cooler in the driving gearbox to ensure that the cooling water will not flow out of th...

Abstract

The invention discloses a cooler in a driving gearbox. The cooler in the driving gearbox is in the cylindrical structure with an opening in the top, and is characterized in that a first sealing plate which is annular is arranged on the top of the body of the cooler, a second sealing plate which is annular is arranged at the bottom of the body of the cooler, annular separation layers are further arranged on the body of the cooler and between the first sealing plate and the second sealing plate, the separation layers, the first sealing plate and the second sealing plate are arranged at intervals in the axial direction, a water pass notch is formed in each separation layer, and the water pass notches of every two adjacent separation layers are staggered by a certain angle in the circumferential direction of the separation layers. The cooler in the driving gearbox is simple in structure, small in occupied space, large in heat dissipating area, long in cooling flow path, good in cooling effect and reliable in sealing. The invention further provides a cooling structure and method of the driving gearbox.

Description

technical field [0001] The invention relates to a cooler in a drive gear box, which is used for cooling the drive gear box of a main cutter head of a shield machine. The invention also relates to a cooling structure and method of the drive gear box. Background technique [0002] The working location of the shield main cutter head drive gearbox is below the ground at a depth of more than ten meters. Due to the harsh working environment such as high heat, high temperature, and poor ventilation conditions in the underground, as well as the large workload and large heat generation of the shield machine main cutter head drive gearbox, Under the working condition of small heat dissipation space, it is necessary to provide a reliable and effective cooling and heat dissipation device for the main cutter head drive gearbox of the shield machine to ensure the normal excavation work of the shield machine. [0003] Conventional cooling methods for the main cutter head drive gearbox of...
