This invention relates to the field of electric spindle technology and discloses a cooling mechanism and method for the electric spindle of a permanent magnet synchronous motor. The mechanism includes a spindle housing with a coolant inlet pipe and a coolant outlet pipe. Inside the spindle housing are a steel cylinder and a cooling sleeve with cooling channels. A tail cap is installed at the tail end of the spindle housing, and a rotary joint is provided on the tail cap. A cooling assembly is installed inside the spindle housing. This invention, through the design of the cooling assembly, including a rear cooling chamber, a bushing channel, a stator ventilation area, a front bearing cooling channel, a water-cooled ring, a steel cylinder cooling channel, a motor water-cooled sleeve annular dual-flow cooling groove, and a rear seat cooling channel, achieves multi-directional cooling of key components such as the rear bearing, front bearing, and stator of the electric spindle.

According to the anti-sticking coating for sintering, TiN or TiC serves as an anti-sticking and blocking material, MgO serves as a shell forming agent, MgO and a TiO2 oxide film formed on the surface of the TiN or TiC form a magnesium titanate (MgTiO3) ceramic phase through a solid-solid diffusion reaction, the magnesium titanate ceramic phase is connected with coarse TiN or TiC particles after high-temperature sintering, and the anti-sticking coating for sintering is obtained. A relatively hard TiN or TiC shell is formed, so that the friction resistance and scratch resistance of the coating are improved, and the service life of the coating is prolonged. According to the sintering tray coated with the anti-sticking coating for sintering, the surface of the coating is free of peeling, cracking and other defects after sintering, the coating is completely reserved, the good and stable barrier effect is achieved, and the problems that impurities are likely to be introduced into an existing sintering anti-sticking coating, the sintering anti-sticking coating reacts with sintered alloy at the high temperature, and the performance of a sinter is deteriorated are solved.

The utility model provides a high temperature resistant cable multi-layer heat insulation protection structure, relates to the cable protection structure field, and comprises a heat insulation protection sleeve and a high temperature resistant cable body, the high temperature resistant cable body passes through the heat insulation protection sleeve inner side, and the heat insulation protection sleeve inner side is provided with a compression resistant structure layer; the pressure-resistant structure layer contains a nano aluminum oxide V-shaped strip and a nano aluminum oxide U-shaped strip, fluoroplastic layers are bonded to the inner side end faces of the nano aluminum oxide V-shaped strip and the nano aluminum oxide U-shaped strip, the inner side faces of the fluoroplastic layers are wrapped with rock wool heat preservation layers, the inner side faces of the rock wool heat preservation layers are wrapped with halogen-free flame-retardant layers, and the outer side faces of the halogen-free flame-retardant layers are wrapped with halogen-free flame-retardant layers.
