[0005] However, in the prior art, the outer ring of the bearing to be tested is placed on the air-floating platform. When the air-floating platform rotates, the outer ring of the bearing is driven by the surface friction with the outer ring of the bearing. slippery, making the measured data incomplete

The present invention provides a bearing outer ring external diameter detection apparatus. The apparatus comprises four positioning wheels that are disposed in a coplanar manner. The four positioningwheels are opposite to each other in pairs, and are commonly connected on a same circumference, wherein one pair is driving wheels and the other pair is driven wheels. The pair of driving wheels is separately installed on a rotary motor and rotates at the same speed and in the same direction. An external diameter dial indicator is disposed in the middle of the pair of driven wheels, and a measuring head of the external diameter dial indicator is also connected to the circumference. A space enclosed by the circumference is used for placing a to-be-detected bearing outer ring. During operation,the bearing outer ring is positioned in the middle of the four positioning wheels, the measuring head abuts an outer peripheral face of the bearing outer ring, and the pair of driving wheels rotate todrive the bearing outer ring to rotate, so that the external diameter dial indicator obtains external diameter detection data of the bearing outer ring.
Description
technical field [0001] The invention relates to the field of bearing detection, in particular to a detection device for the outer diameter of a bearing outer ring. Background technique [0002] Deep groove ball bearings consist of an outer ring, an inner wheel, balls and a cage. In order to ensure that the inner ring of the bearing and the balls with the cage can be well loaded into the outer ring of the bearing, the outer ring of the bearing needs to be inspected before assembly of the existing deep groove ball bearing. [0003] The consistency of the outer diameter of the outer ring of the bearing is a very important parameter for the bearing. If the outer diameter consistency is poor, the noise of the bearing will be increased and the service life will be reduced. The outer diameter detection method of the bearing outer ring in the prior art is still in the static measurement stage of semi-automatic and manual detection. The outer diameter detection usually uses a mechan...
