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 and relates to the field of mechanical manufacturing. The magnetic gear transmission pair is composed of a gear A, a gear B1, a gear B2, a gear B1 magnet and a gear B2 magnet; the gear B1 and the gear B2 are coaxial, are the same in diameter, and are the same in tooth number; the gear B1 and the gear B2 are attached together; the gear A isengaged with the gear B1 and the gear B2; torque is input by the gear A, and is transmitted to the gear B1 and the gear B2 through teeth to be output; a plurality of magnets are installed in the gearB1 and the gear B2; and the gear B1 magnet and the gear B2 magnet are installed in a homopolar and opposite manner. The magnetic gear transmission pair has the beneficial effects that due to the homepolar repulsion principle of the magnets and by means of the magnetic force effects, the gear B1 and the gear B2 are made to rotate in opposite directions, and make contact with the two sides of the tooth part of the gear A on engagement points at the same time, and therefore gear backlash is eliminated, and the gear transmission and indexing precision is improved.

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...
