Technical Field
The utility model relates to a bearing field specifically, relates to a low-speed high temperature enhancement mode graphite holder deep groove ball bearing.
Background
The bearing is a component for fixing the position and reducing the friction coefficient in the mechanical transmission process, and can be used for reducing the friction coefficient in the power transmission process and keeping the central position of the shaft fixed when other parts move relative to each other on the shaft. The bearing is a lightweight component in mechanical equipment, and the main function of the bearing is to support a mechanical rotating body so as to reduce the friction coefficient of the equipment in the transmission process.
In order to improve the bearing capacity of the rolling bearing, the conventional low-speed high-temperature deep groove ball bearing is of a full-load rolling body structure without a retainer, and is usually lubricated by high-temperature lubricating grease. The low-speed high-temperature deep groove ball bearing works in a high-temperature environment, grease components in high-temperature grease filled initially are firstly evaporated, only residual solid components play a lubricating role, the amount of the solid components is small, the good lubrication of the bearing is not enough to be maintained for a long time, and therefore the high-temperature grease needs to be filled again in a short time. The existing lubricating grease can not meet the lubrication under the high-temperature working condition because of the lack of high-temperature lubricating grease resistant to more than 400 ℃ in China all the time and under the ultra-high temperature condition (the working condition temperature is approximate to 627 ℃), and in order to solve the problems, a low-speed high-temperature enhanced deep groove ball bearing with a graphite cage is designed. CN105673699A provides a high temperature resistant high leakproofness deep groove ball bearing, and oil filling cavity is enclosed to its bearing inner circle, bearing outer lane and two protective covers and is equipped with the oil filler point on the protective cover, adopts high temperature grease lubrication.
