Self-aligning roller bearing installed on the stability of maintenance steps to common problems

In the process of using the timken bearing, special for bearing lubrication, to pay more attention to the amount of grease. How accurately using grease and ask you must understand the grease in the bearing 6316 - In the 2 rs movement status to ensure the stability of the grease. Fill in the rolling bearing grease movement, follow the changes of bearing, generally can be divided into two stages. Differences of grease in the bearing is divided sample outline of open to traffic, must constitute the outline is quite is, go should be short, in is self-aligning roller bearing during operation of low temperature, and smooth, this is a kind of more fantasy grease, so the lubricating grease into the canal of special priority. In popular conditions, timken bearing grease filling amount, in always goes beyond the practice demand directly involved in the lubrication, full frame and bearing cover of the cavity, and an outline is made in the rolling around in vitro. In the process, because of excess grease resistance, bearing temperature rise quickly. Although most redundant grease at the beginning of the operation is being squeezed out, and squeezed in the raceway attachment grease could still be migration transformation between the rolling element into the race. Most of these in the early stages of the bearing running grease quickly ( Less than a minute) Is being squeezed out of raceway and accumulate in bao followed the spherical roller bearing grease migration cyclic shift body, also have a small amount of discharge. Bearing (degrees still continues to rise at this moment, until all redundant grease were discharge, may be called the grease running-in stage, according to the structure of the bearing grease, filling quantity elements such as quality, this paragraph of time may last ten minutes, and even a few hours. At the time of anti friction bearing filling grease, may not need to use the theory of high pressure, unless very careful to use. High pressure can damage the bearing, waste grease, excessive grease caused by high temperature dangerous and surrounding the timken bearing invisible environment. In most applications, the ball or roller bearing lubrication, if grease level accounted for a third to a half of bearing capacity. Beyond the amount of usually will be sealed shell discharge and waste. 1, the installed on surface and the place has a requirement? If spherical roller bearing with iron filings, burr, dust and other foreign matter to enter, will make the bearing noise and vibration during operation, and even damage raceway and rolling body. So, before the installation of bearings, you must ensure that the installation surface and the environment clean. 2, bearing must be cleaned before installed? Bearing surface coated with anti-rust oil, you must use clean petrol or kerosene cleaning carefully, then coated with clean, high quality or high speed high temperature lubricating grease before installation. Cleanliness of bearing life and the influence of vibration noise is very big. But we especially want to remind you is: fully enclosed bearing not clean fuel. 3, how to select grease? Lubrication of imported bearings of work and life have very important influence. Here a brief introduction to select the general principles of the grease to you. Grease made out of base oil, thickener and additive, different types and different type of same kind grease properties vary widely, allowing the rotation of the limit, when the choice is important to note. The performance of the grease is mainly determined by the base oil. The basis of generally low viscosity oil is suitable for low temperature, high speed; High viscosity is suitable for high temperature, high load. Thickener and relationship with lubrication performance, thickening agent, water resistance to the water resistance of the grease. In principle, different brand of grease can't mix, and even the same thickening agent of grease, will also bring bad influence each other on the basis of different additives. 4, when lubricated bearing, oil paint, the more the better? Lubricated bearing, oil paint, the more the better, this is a common mistake. Spherical roller bearings and bearing indoor excessive grease will cause excessive oil mixing, resulting in a high temperature. 5, how to install and disassemble? Don't directly when installation hammer spherical roller bearing end face and the bearing surface, should be to press, sleeve or other installation tools for uniform bearing force. If the installation surface coated with lubricating oil, will make the installation more smoothly. If the interference fit is larger, should put the bearing into the mineral oil heating to 90 ~ 100 ℃ in immediately after installation. When removing difficulties, it is recommended that you use disassembly tool to pull at the same time to careful labor the inner ring of hot oil, heat can make the bearing inner ring expansion, making it easier to fall off.
