The invention discloses a hydrological drilling abrasion-resisting device structurally comprising a bearing, a fixing hole, a top connecting disc, a power connecting block, a fixing bolt, a sleeve, a connecting rod, an abrasion resisting pattern, a drill bit, a top cover, a fixing sleeve and a bottom connecting disc. The bearing is composed of a roll ball, a middle fixing sleeve, an outer ring sleeve and an inner ring sleeve, the side face of the roll ball and the interior of the middle fixing sleeve adopt clearance fit, the inner side of the outer ring sleeve and the side face of the roll ball are movably connected, and the side face of the roll ball is movably connected with the outer side of the inner ring sleeve. The outer side of the outer ring sleeve is fixedly connected with the inner sides of the top connecting disc and the bottom connecting disc. According to the hydrological drilling abrasion-resisting device, the bearing is additionally arranged to support a mechanical rotary body, the friction coefficient in the movement process of the mechanical rotary body is decreased, the rotation accuracy of the mechanical rotary body is ensured, and the using value of equipment is improved.
Description
technical field [0001] The invention is an anti-wear device for hydrological drilling, which belongs to the field of anti-wear devices for hydrological drilling. Background technique [0002] The anti-wear device for hydrological drilling is to prevent equipment from being damaged by friction during drilling. [0003] The prior art publication application number is: 201520709678.7 The invention discloses a downhole mud generator with an anti-wear device, including an impeller, a main shaft and a transmission shaft. A transmission shaft is installed inside, and the interior of the transmission shaft is inlaid with an internal magnetic coupling. The rotor is fixed at one end of the transmission shaft, and the stator is set at a distance of 1 to 2mm from the rotor. An anti-wear device is installed on the main shaft, and the anti-wear device includes a A helical groove on the main shaft, and a spring wire is nested in the helical groove. The invention installs an anti-wear dev...
