The quilt general axis bearing as a rolling bearing and a sliding bearing can be divided into two categories. Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.
Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery.
According to the spinning process, carding is an important process. The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). Bearing material is cast bronze, copper, or iron-based powder metallurgy oil uranium lining, nylon and other sour laminates.
Roller needle ball bearing and two bearings and central. Using the needle roller uranium cool quilt production line system, its radial diameter can be smaller than that of the ball, and it is easier to adapt to the spinning process requirements of the roll diameter and the officially specified pitch of the roll center. When nursing must use the following problems, it should be considered: 1. The problem of short velvet and flying flowers Most of the textile mills operate continuously in three shifts, and the fibers accumulated on the neck of the drafting roller are easy to develop into Chinese bearings, especially in the high-speed operation environment of the economy. Lack of oil, heat, and even burns.
The root cause of the old copper-lined bearing has no dust-proof technical measures. The bearing-type oil-impregnated bearing has a mooring pad (made of oil-filled foam plastic) and a dust cover to prevent flying flowers from invading. For a rolling bearing, since we hope that it will not be added for a long time, on the one hand, we should try our best to increase the oil content in the design of the structural system, on the other hand, we need to put forward a higher quality requirement for different sealing and dustproofing. Nylon materials are prone to expansion after being heated, and the general method is not suitable for use in high-speed parts.
2. The problem of refueling the yarn sliding bearing oil should be spared no effort to prevent the loss of oil. Better by scrolling. 3. Adjust the bearing at different heights. Due to the error analysis of the manufacturing system of parts such as bearings and roller seats in China and the deformation of the frame structure, each roller bearing should consider the market adjustment and teaching links, so that the height of the rollers is basically the same.
The old copper lining is unified with the roller sickle cone pad and the wrapping welding. After using various oil-containing bearing bushes, the back of the bearing bush can be chained or used to solve the problem. When a rolling bearing is used, it can only be solved by the pad method.
