Abstract

The invention discloses a rolling bearing grinding machine for wheel pairs of railway freight cars. Grinding devices are arranged at both ends of a stand symmetrically, and each grinding device comprises a motor [1], a transmission device, a friction transmission wheel [11] and a pivoting support [16], wherein the outer end of the pivoting support [16] is connected with a frame [19] which is fixed on the stand through a rotating shaft [18], while the inner end is supported on the frame; and the weight born by the pivoting support [16] is applied onto a rolling bearing [12] through the friction transmission wheels [11], so that the weight of workpiece objects participating in rotation is reduced greatly, consumed power is reduced, and the abrasion of a friction wheel is reduced. The frames and the stands of the grinding devices are connected glidingly. The rolling bearing grinding machine is suitable for grinding wheel pair rolling bearings with different specifications, and has good equipment universality.

Description

technical field [0001] The invention relates to a press-fitting and running-in equipment for rolling bearings of railway freight wheel pairs. Background technique [0002] The rolling bearings at both ends of the railway freight wheel pair must be subjected to a running-in test. The original running-in test equipment uses a friction wheel to drive the wheel rim to make the entire wheel set rotate (220 rpm). The bearing shell has a pair of pressing devices that will It is fixed to make it rotate relative to each other, and the temperature (<60° C.) is detected by a far-infrared thermometer. This equipment has three disadvantages: one is that the workpiece object participates in the rotation of the friction wheel, which wears a lot and is frequently replaced; the other is that it consumes a lot of power; Contents of the invention [0003] The invention provides a rolling bearing running-in machine for railway freight wheel sets, which has the advantages of low power cons...
