Description

Material of bearing in hydraulic machinery
Technical Field
The invention discloses a material for a bearing in a hydraulic machine.
Background
The bearing in the hydraulic machinery is one of important component parts, and the bearing requires higher precision, stronger anti-plasticity ability and lower coefficient of friction, and among the prior art, the bearing in the hydraulic machinery can only mostly satisfy the requirement of coefficient of friction and precision, and to anti-plasticity ability, current bearing can not satisfy, the condition that the life of bearing is shorter often can appear.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a material for a bearing in a hydraulic machine, which has the advantages of strong plasticity resistance, low friction coefficient, high precision of the bearing and capability of well keeping the precision not damaged.
In order to achieve the purpose, the invention is realized by the following technical scheme: the material for the bearing in the hydraulic machinery comprises the following raw materials in percentage by weight: 0.5-6% of trisodium phosphate, 10-35% of polydimethylacrylamide, 1-10% of nano calcium carbonate, 0-3% of silane coupling agent, 0-2.5% of polyvinylidene fluoride, 5-20% of epoxy resin, 10-20% of montmorillonite and 30-60% of catalyst.
Has the advantages that: the product prepared by the method has strong plasticity resistance, low friction coefficient, high precision of the bearing and capability of well keeping the precision not damaged.
Detailed Description
Example 1
The material for the bearing in the hydraulic machinery comprises the following raw materials in percentage by weight: 0.5 percent of trisodium phosphate, 10 percent of polydimethylacrylamide, 1 percent of nano calcium carbonate, 1 percent of silane coupling agent, 1 percent of polyvinylidene fluoride, 5 percent of epoxy resin, 10 percent of montmorillonite and 30 percent of catalyst, wherein the precision of the bearing is insufficient.
Example 2
The material for the bearing in the hydraulic machinery comprises the following raw materials in percentage by weight: 6 percent of trisodium phosphate, 35 percent of polydimethylacrylamide, 10 percent of nano calcium carbonate, 3 percent of silane coupling agent, 2.5 percent of polyvinylidene fluoride, 20 percent of epoxy resin, 20 percent of montmorillonite and 60 percent of catalyst, and the plastic resistance of the bearing is insufficient.
Example 3
The material for the bearing in the hydraulic machinery comprises the following raw materials in percentage by weight: 4% of trisodium phosphate, 23% of polydimethylacrylamide, 5% of nano calcium carbonate, 1.5% of silane coupling agent, 1.25% of polyvinylidene fluoride, 13% of epoxy resin, 15% of montmorillonite and 45% of catalyst, so that the bearing has extremely strong plasticity resistance, low friction coefficient, extremely high precision and can well keep the precision undamaged.
