摘要： A support apparatus for a shaft system. The shaft system comprises a first shaft (1), a second shaft (2), and a bearing (3) arranged between the first shaft (1) and the second shaft (2); the first shaft (1) is sleeved at an outer peripheral side of the second shaft (2) and is able to rotate relative to the second shaft (2) by means of the bearing (3). The support apparatus is used for arranging at a first end in an axial direction of the shaft system, and the support apparatus comprises: shaft end support members (8, 15), at least a portion of the shaft end support members (8, 15) being rotatably supported in an axial direction at an outer side of a shaft end face of a first end of the second shaft (2); and connection assemblies (17, 14), where the connection assemblies (17, 14) in the axial direction of the shaft system are used for being connected between a first end of the first shaft (1) and the shaft end support members (8, 15). Further disclosed is a wind turbine. The present support apparatus may enable a bearing of a shaft system to essentially not bear a load or reduce an axial load borne, and the service life of the bearing is prolonged.

摘要： The invention provides a rolling bearing lubricating method and device, which are capable of showing stabilized temperature rise while securing lubrication reliability. This rolling bearing lubricating method, which is a lubricating method for feeding lubricating oil during operation of a rolling bearing, comprises the step of automatically or manually changing the feed rate of lubricating oil during operation by a feed rate changing means (102) in order to keep the temperature of a rolling bearing (103) in a preset permissible range. The feeding of lubricating oil is effected in an air oil state by using a lubricating oil feeding means (101). The feed rate of lubricating oil is changed according to the rotative speed of the rolling bearing (103). The feed rate change of lubricating oil according to the rotative speed is effected under a plurality of lubrication conditions with the lubricating oil feed rate varied, on the basis of the sampling result obtained by sampling data on temperature rise for the rolling bearing (103) according to the rotative speed.

摘要： A method for forming a fully or partly filled roller bearing of very small axial dimension and high loading capacity, in which the rollers (23) are retained between the two cylindrical guide and rolling tracks of the inner race (11) and outer race of the bearing by at least one small-thickness lateral shoulder-forming ring (25) with its inner edge of frusto-conical shape, and which after being expanded preferably by heating, is inserted into a corresponding annular housing groove (26) provided in an edge of said bearing inner race (11), said groove (26) having a wall of frusto-conical shape flared towards the interior of the race and with a mouth of diameter slightly greater than the minimum diameter of said lateral shoulder-forming ring. The bearings formed in this manner are also claimed.
