Description
Technical field
The invention belongs to extra large size bearing raceway groove measurement apparatus field, and in particular to a kind of super-huge deep groove ball bearing inner ring
Or outer ring raceway position-measurement device.
Background technology
Deep groove ball bearing of the external diameter more than 440 millimeters is also referred to as super-huge deep groove ball bearing, super-huge deep groove ball bearing
Lasso be broadly divided into 11 two kinds of inner ring 12 and outer ring, to bearing ring carry out arc surface raceway groove process when, processed
The distance of channel center plane and the given datum end face in bearing both sides have to comply with design tolerance.Due to the dimensional variations
Amount directly affects bearing completed products assembling height and running accuracy, therefore, it is necessary to the position chi of the channel center plane to bearing completed products
It is very little to do necessary quality testing.
As shown in figure 1, distance of the central plane of the bear inner ring grooved railway Ri of measurement needed for inner ring 12 to inner ring datum end face D
For Wi ± Δs Wi；Existing simple measurement method is as shown in Fig. 2 old simple position model 13 includes datum plate 13-1, branch
Plate 13-2 and big model 13-3, big model 13-3 external diameter with it is required detection raceway groove normal diameter it is identical, big model 13-3 and
Datum plate 13-1 is connected by support plate 13-2；Datum plate 13-1 side is leaned against on the datum end face D of inner ring 12 during detection, and
Big model 13-3 is pressed close to bear inner ring grooved railway Ri center, the method estimated by bore hole observes connecing for big model 13-3 and raceway groove Ri
The situation of touching, and measure by the subjective experience of survey crew and judge whether the contact area both it can meet or exceed inner ring
More than the 85% of raceway groove Ri cross sections, it is unqualified if not up to standard to be considered as product.
Outer ring raceway Re machined parameters are detected and judged using same measurement apparatus and method, such as Fig. 3 to Fig. 4
It is shown, still using simple position model 13 to the distance We of outer ring raceway Re central plane to outer ring datum end face A ±
Δ We is detected, and judges whether it is qualified with same standard by survey crew.
, when in use need to also be by testing staff by the horizontal stroke of its end face and tested raceway groove because big model 13-3 is planar structure
Section is consistent, and this necessarily introduces human error factor, is not easy accurately to control, in addition, existing pass through simple position model 13
Detection, and accurate and reliable specific measurement can not be provided by testing staff's range estimation and the subjective method for estimating contact surface compactness
Numerical value, is a kind of rough qualitative method rather than quantitative approach, and its testing result includes subjective factor and artificial measurement error
Interference, inadequate science and accurate, therefore urgently improve.
The content of the invention
Needed to solve the model of the super-huge deep groove ball bearing inner ring of existing measurement or outer ring raceway position by detecting people
