Embodiment 1

[0022] Example 1. ZrO 2 Bonding of full ceramic to metal shaft

[0023] (1) Preparation of epoxy resin / phenolic resin adhesive

[0024] Proportionate epoxy resin and phenolic resin, epoxy resin 95-100phr, phenolic resin 59-63phr, dissolve with volatile solvent, mechanically stir evenly, vacuum defoaming at 70-75°C.

[0025] (2) Preparation of epoxy resin / phenolic resin / CaO adhesive

[0026] Disperse 2.5-3.0phr nano-scale CaO into the mixed solvent, then add the prepared epoxy resin / phenolic resin glue, mechanically mix and stir evenly. Vacuum removes air bubbles to increase the viscosity of the mixed glue to stabilize the dispersion of nanoparticles. Seal the prepared glue for later use. The smaller the nanoscale CaO particles are, the easier it is to disperse uniformly. Considering the cost and the possibility of commercial availability, CaO with a size of 100-500 nanometers is suitable.

[0027] (3) Selection of metal inner ring and surface roughening treatment

Abstract

The invention relates to an adhesive for bonding a full-ceramic bearing and a metal shaft and an application method thereof. The adhesive is an organic and inorganic composite adhesive which takes epoxy resin as the base and phenolic resin as curing agent and is added with nanoscale CaO, wherein 95-100phr of epoxy resin, 59-63phr of phenolic resin and 2.5-3.0phr of nanometer CaO with epoxy resin and phenolic resin as basis are taken. When in use, a metal inner ring is additionally arranged between the inner race of the full-ceramic bearing and the metal shaft, and the metal inner ring and the inner race of the ceramic bearing are bonded by the adhesive provided by the invention. The invention effectively solves the problem of mechanical connection between the full-ceramic bearing and the metal shaft and has simple operation, and simultaneously, the provided composite adhesive overcomes the defects of organic adhesive and inorganic adhesive and improves the bonding property.

Description

technical field [0001] The present invention relates to an adhesive used for bonding a full ceramic bearing to a metal shaft and a method of use thereof, more precisely, the present invention relates to an adhesive capable of effectively bonding the inner ring of a full ceramic bearing to a metal inner ring and a method of use thereof. The best adhesive is a composite glue of inorganic glue and organic glue. Background technique [0002] As an important mechanical basic part, ceramic bearings are in the lead in the world of new materials due to their excellent performance, high temperature resistance and super strength, which are incomparable to metal bearings. In the past ten years, it has been increasingly widely used in various fields of national economy and people's livelihood. Aerospace, navigation, nuclear industry, petroleum, chemical industry, light textile industry, machinery, metallurgy, electric power, food, locomotive, subway, high-speed machine tools and scient...
