Problems solved by technology

The existing rubber used to make the shaft sleeve assembly is ordinary rubber, and its shortcomings are: (1) poor heat resistance, so the vulcanization temperature is low during high-temperature vulcanization molding, resulting in long vulcanization time and low processing efficiency; 2) The aging resistance and bonding strength are low. After vulcanization and molding, the adhesion between the rubber part and the metal bushing and iron sheet is not enough, and the rubber part is easy to age and deform, resulting in a short service life of the bushing assembly

Embodiment 1

[0013] The rubber used on the shaft sleeve assembly of a fan is obtained by mixing and vulcanizing the following components in parts by mass: 100 parts of nitrile rubber, 5 parts of zinc oxide, 2 parts of stearic acid, 0.7 part of sulfur, and 1 part of feed agent TMTD, 1.5 parts of vulcanization accelerator DM, 37.5 parts of semi-reinforcing carbon black, 13 parts of carbon black 330, 20 parts of barium sulfate, 5 parts of vaseline, 1 part of anti-aging agent 4010NA.

[0014] The weight of 1 part in the above components is 1 kg. The manufacturing process of the rubber used on the shaft sleeve assembly of the fan is as follows: the above-mentioned nitrile rubber, zinc oxide, stearic acid, sulfur, accelerator TMTD, vulcanization Accelerator DM, semi-reinforcing carbon black, carbon black 330, barium sulfate, vaseline and anti-aging agent 4010NA are put into the internal mixer for banburying, and the rubber block after banburying is put into the open mixer to open, and then pulled...

Embodiment 2

[0016] The rubber used on the shaft sleeve assembly of a fan is obtained by mixing and vulcanizing the following components in parts by mass: 100 parts of nitrile rubber, 4 parts of zinc oxide, 1 part of stearic acid, 0.6 part of sulfur, and 0.9 parts of TMTD, 1.4 parts of vulcanization accelerator DM, 36 parts of semi-reinforcing carbon black, 11 parts of carbon black 330, 19 parts of barium sulfate, 4 parts of vaseline, 0.9 parts of anti-aging agent 4010NA. Manufacturing process is identical with embodiment 1.

Embodiment 3

[0018] The rubber used on the shaft sleeve assembly of a fan is obtained by mixing and vulcanizing the following components in parts by mass: 100 parts of nitrile rubber, 6 parts of zinc oxide, 3 parts of stearic acid, 0.8 part of sulfur, and 1.2 parts of TMTD, 1.8 parts of vulcanization accelerator DM, 40 parts of semi-reinforcing carbon black, 15 parts of carbon black 330, 22 parts of barium sulfate, 6 parts of Vaseline, 1.2 parts of anti-aging agent 4010NA. Manufacturing process is identical with embodiment 1.

Abstract

The invention relates to the field of rubber, in particular to rubber used on a shaft sleeve assembly of a fan. The rubber is prepared by compounding and vulcanizing 100 parts by mass of nitrile rubber, 4-6 parts by mass of zinc oxide, 1-3 parts by mass of stearic acid, 0.5-0.8 part by mass of sulfur, 0.8-1.2 parts by mass of an accelerator TMTD (Tetramethyl Thiuram Disulfide), 1.3-1.8 parts by mass of a vulcanization accelerator, 35-40 parts by mass of semi-reinforcing carbon block, 10-15 parts by mass of carbon black 330, 18-22 parts of barium sulfate, 4-6 parts of vaseline and 0.8-1.2 parts of aging resistant 4010 NA. The rubber used on the shaft sleeve assembly of the fan has the advantages of high heat resistance, difficulty in causing aging and deformation of a rubber part and long service life of the shaft sleeve assembly.

Description

technical field [0001] The invention relates to the field of rubber, in particular to rubber used on shaft sleeve assemblies of cross-flow fans, axial-flow fans, centrifugal fans and diagonal-flow fans. Background technique [0002] Fans mainly include cross flow fans, axial flow fans, centrifugal fans and oblique flow fans. The shaft sleeve assembly is one of the important parts of the above fans. The main function of the shaft sleeve assembly on the fan is to assemble and connect with the motor shaft. When in use, the motor shaft The fan is driven to rotate through the shaft sleeve assembly. The shaft sleeve assembly is composed of shaft sleeve, rubber parts and iron sheet. During the production of the shaft sleeve assembly, the aluminum sleeve and iron sheet are processed first, and then the shaft sleeve, iron sheet and rubber are put into the vulcanization molding of the shaft sleeve assembly. High temperature vulcanization molding in the machine. The existing rubber u...
