specific Embodiment approach 1

[0046] Embodiment 1: A method for gluing a phenolic resin adhesive tape for manufacturing a bearing cage described in this embodiment is carried out according to the following steps:

[0047] 1. Prepare glue:

[0048] Pour the phenolic resin glue into the glue tank; after the phenolic resin glue is cured at a temperature of 103°C to 107°C for 1.5h to 2.5h, the solid content is 54% to 62%. Under the condition of 158°C-162°C, the gelling time of bonding copper sheets to copper sheets is 60s-90s, the free phenol content of the phenolic resin glue is ≤15%, and the specific gravity of the phenolic resin glue is 1.04-1.07;

[0049] Second, cloth preparation:

[0050] 109 Natural muslin cloth prepared for use in the rubber category;

[0051] 3. Turn on the dryer:

[0052] Turn on the dryer, and set the drying temperature of the three stages at 127°C to 133°C;

[0053] 4. Turn on and adjust the glue machine:

[0054] Turn on and adjust the gluing machine, the gap between the nip ...

specific Embodiment approach 2

[0095] Embodiment 2: This embodiment differs from Embodiment 1 in that: in step 3, the dryer is turned on, and the drying temperature of the three stages is set at 130°C. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0096] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: open and adjust the gluing machine in step four, the gap between the nip rollers is 0.19mm, adjust the rotation speed of the rollers so that the pointer of the ammeter is at 65A, And make the transmission speed of the transmission cloth 1.7m / min. Others are the same as in the first or second embodiment.

Abstract

The invention relates to a phenolic resin adhesive cloth gluing method, in particular to a phenolic resin adhesive cloth gluing method used for manufacturing a bearing retainer. The problems that in the existing gluing process for producing phenolic resin adhesive cloth, control is not easy, the quality of glued cloth is easily changed, and in the production process and the detection process, changing is not easily found are solved. The method comprises the steps of 1, glue preparing, 2, cloth preparing, 3, drying machine starting, 4, gluing machine starting and adjusting, 5, cloth feeding glue dipping, 6, roller glue scraping, 7, one-segment drying, 8, second-segment drying, 9, three-segment drying, 10, sampling, 11, rolling, 12, detecting and 13 presenting. The phenolic resin adhesive cloth gluing method used for manufacturing the bearing retainer is finished. The phenolic resin adhesive cloth gluing method is used for manufacturing the bearing retainer.

Description

technical field [0001] The invention relates to a gluing method for phenolic resin tape. Background technique [0002] In the bearing industry, some bearings often use non-metallic materials such as phenolic resin tape as a cage during design. As a key component to control the precise movement of rolling elements, this cage has the characteristics of light weight, small centrifugal force, low noise, wear resistance and good self-lubrication performance, and is widely used in aerospace, navigation, high-speed grinding spindle bearings and precision Instrumentation, gyroscope bearings. [0003] Phenolic resin tape is used as a raw material for manufacturing hollow cylindrical high-strength tape cage blanks, and its quality determines the quality of this bearing cage. [0004] However, the gluing process of producing phenolic resin tape is a special process, the process is not easy to control, and it is easy to cause changes in the quality of the gluing cloth. It is not easy ...
