Embodiment

[0022] Embodiment: A method and device for measuring the gap between series pairs of single-row tapered bearings. The working object of the present invention is two paired bearings, called bearing first 14 and bearing second 15 respectively. A paired bearing set provided by a general bearing supplier includes a bearing A 14 and a bearing B 15 , and also includes an inner spacer 21 and an outer spacer 22 . The paired bearing set provided by the bearing supplier is shown in Figure 6 (in order to mark the distance H between the adjacent end faces of the outer rings of two series bearings in the figure, the outer spacer ring 22 on one side is not shown). In the figure, c represents the end face adjacent to the inner ring 17 of bearing A and the inner ring 19 of bearing B, d represents the end face adjacent to the outer ring 16 of bearing A and the outer ring 18 of bearing B, c 1 Indicates the end face adjacent to the inner ring 19 of bearing B and the inner ring 17 of bearing A, ...

Abstract

The invention discloses a mating clearance measuring method and device for single-row conical bearings in series. The method comprises the processes: first, a bearing A, an inner spacer, a bearing B and a platen are sequentially sleeved on a mandrel of a base; a nut A is sleeved on a thread A of the mandrel, a housing washer of the bearing B is rotated while the nut A is tightened, causing the platen to press the housing washer of the bearing B tightly; a support arm-panel part is arranged on the mandrel, causing a pawl of the support arm-panel part to press on a housing washer of the bearing A; a nut B is sleeved on the thread B of the mandrel, the housing washer of the bearing A is rotated while the nub B is tightened, causing the pawl of the support arm-panel to press tightly on the housing washer of the bearing A; then the distance between the two adjacent end faces and the heights of the housing washers of the two bearings are measured respectively and the distance between the two adjacent end faces of and the height difference between the two housing washers are calculated, thus, the mating clearance of the single-row conical bearing in series is obtained. The measuring method is characterized by high measuring accuracy, easy operation, etc. and can improve the measuring efficiency.

Description

technical field [0001] The invention relates to bearing measurement, in particular to a method and a device for measuring the serial pairing clearance of single-row tapered bearings. Background technique [0002] In order to improve the load-bearing capacity of the rotating parts and ensure the reliability of the product, single-row tapered bearings are used in series at both ends of some rotating parts. However, since the paired bearings currently used are randomly paired and used randomly, the paired bearings have an inappropriate pairing gap, resulting in uneven stress on the two bearings used in series pairing, and some bearings are prematurely damaged or invalid. Failure interlocking causes premature damage or failure of other components or components, which seriously affects the service life of the product. The economic loss caused by this situation is immeasurable. As for the measurement method of the series pairing clearance of tapered bearings, some bearing supplie...
