Embodiment 1
[0032] Embodiment 1: 42-52 parts of mineral oil, 5-10 parts of stearic acid, 5-8 parts of superfine silica powder, 1-5 parts of silane coupling agent, 1-3 parts of nano filler, 1-3 parts of antioxidant, 1-3 parts of surfactant, 1-3 parts of defoamer, 25-30 parts of water.
[0033] The anti-overheating wear agent can resist friction for 3 hours, and the temperature is controlled at 280-300°C to reduce friction and wear caused by high temperature. The average wear speed is 50% lower than that of smearing.
Embodiment 2
[0034] Embodiment 2: 42-52 parts of mineral oil, 5-10 parts of stearic acid, 5-8 parts of superfine silica powder, 1-5 parts of silane coupling agent, 1-3 parts of nano filler, 1-3 parts of antioxidant, 1-3 parts of surfactant, 1-3 parts of defoamer, 25-30 parts of water.
[0035] The anti-overheating wear agent can resist friction for 4 hours, and the temperature is controlled at 260-290°C to reduce friction and wear caused by high temperature. The average wear speed is 60% lower than that of smearing.
[0036] Ultrafine silica powder over 600 mesh.
[0037] The preparation method of the anti-overheating wear agent is as follows: put mineral oil, stearic acid, ultrafine silicon micropowder, and water in a reaction kettle, add a surfactant dropwise, at a temperature of 40.6-70.0°C and a pressure of 0.70-0.95MPa , react until the pressure begins to drop, add antioxidant, react until the pressure is 0.4-0.56MPa, stop adding the silane coupling agent dropwise;

Abstract
The invention discloses a magnetic gear transmission pair, which relates to the field of mechanical manufacturing and consists of gear A, gear B1, gear B2, gear B1 magnet, and gear B2 magnet. The gear B1 and gear B2 are coaxial and have the same diameter , the number of teeth is the same, gear B1 and gear B2 fit together, gear A meshes with gear B1 and gear B2, the torque is input from gear A, and the torque is transmitted to gear B1 and gear B2 through the teeth, and gear B1 and gear B2 are equipped with Several groups of magnets, the gear B1 magnet and the gear B2 magnet are installed oppositely with the same pole. The beneficial effects of the present invention are: a magnetic gear transmission pair, through the principle of repulsion of the same pole of the magnet, uses the magnetic force to make the gear B1 and the gear B2 rotate in opposite directions respectively, and at the meshing point B1, B2 and the tooth of the gear A The two sides of the part are in contact at the same time, thereby eliminating the backlash of the gear and improving the gear transmission and indexing accuracy.
Description
technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a magnetic gear transmission pair. Background technique [0002] In the field of machinery manufacturing, due to the manufacturing error of the gear, the need for lubrication and the prevention of temperature changes, the gear is seized and other reasons. Backlash inevitably exists in the transmission mechanism of the gear. The gear gap will affect the gear transmission mechanism with precision transmission, indexing and other requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a magnetic gear transmission pair. Solve the problem that the gear backlash affects the gear transmission mechanism that requires precision transmission, indexing, etc., and at the same time, solve the problem that the precision transmission caused by gear friction and wear affects the accuracy. [0004] The technical proble...
