Embodiment
With reference to Fig. 1, bearing contact angle and bump volume integrated detector comprise base 1, index dial 3, rotary disk 4, rotating shaft 5, lever 6, support 7, counterweight 8 and gauge head 9, and the last plane of base 1 is for detecting basal plane 10; Detected bearing 2 is placed on and detects on the basal plane 10, and outer ring 13 contacts with detecting basal plane 10, cylindrical 17 location; Rotary disk 4 is placed on the inner ring 15 of bearing, and by brearing bore 16 location, index dial 3 is installed on the rotary disk 4; Support 7 is installed on the base 1; Lever 6 one ends are installed on the support 7 by rotating shaft 5; Counterweight 8 is arranged on the other end of lever 6, and described lever 6 has second arm 12 with described rotary disk 4 relative configurations, makes the gravity of counterweight 8 apply preload by 4 pairs of detected bearings 2 of rotary disk.Described base 1 is provided with and supports lower margin 11.
With reference to Fig. 3,4,5, described gauge head 9 is the pen type sensor, passes the through hole 24 that base 1 is offered, and the sensitive face of upper end is contacted with the end face of the inner ring of measured bearing.Described gauge head 9 is fixed in the screw of offering on the fixed head 18 23.Offer one group of mounting hole 21 on the described fixed head 18, be fixed on the bottom surface of described base 1 by gib screw 19.Described fixed head 18 is a steel spring plate, and the screw 22 that front end offers an open slot 25 and connects Width is finely tuned by 20 pairs of gauge heads 9 of set screw.
One, bearing contact angle detects
With reference to Fig. 2, the present invention realizes that principle of work that bearing contact angle detects is when centre of sphere footpath Dp and sphere diameter Dw are known parameters, by inner ring 15 revolutions, retainer 14 revolutions 1 is enclosed, and detects inner ring 15 and turns over angle, thereby calculate bearing contact angle α.Specify as follows:
As can be seen from the figure, inner ring contact point diameter Dc=Dp-Dw*Cos α
Make inner ring 15 revolutions, steel ball rolls, and outer ring 15 is static, and the steel ball center steering drives retainer 14 revolutions 1 circle.
Because inner ring contact point revolution tangential velocity is 2 times of steel ball center steering tangential velocity, therefore, inner ring contact point revolution tangential distance is 2 times of steel ball center steering tangential distance.
Steel ball center steering tangential distance is that centre of sphere footpath girth is π * Dp
Then inner ring contact point revolution tangential distance is 2 times of above finance minister, i.e. 2 π * Dp
Above-mentioned distance is equivalent to the inner ring revolution number of turns: 2 π * Dp/ π * Dc=2Dp/Dc=2Dp/ (Dp-Dw*Cos α)
Be equivalent to inner ring angle of revolution B=360*2Dp/ (Dp-Dw*Cos α) (1)
Our rotary inner ring makes retainer revolution 1 circle, inner ring revolution B=360*2Dp/ (Dp-Dw*Cos α) degree; Inner ring angle of revolution B when detecting retainer revolution 1 circle just can calculate contact angle α by formula (1):
Cosα=(Dp-720Dp/B)/Dw
α=arcCos(Dp-720Dp/B)/Dw
The index dial of above-mentioned detection method correspondence is made routinely.
Also have a kind of mode,,, use special-purpose index dial,, make retainer revolution 1 circle, directly show bearing contact angle, be described as follows by index dial by the inner ring revolution by calculating at specific bearing:
If contact angle is α, the centre of sphere directly is Dp, and sphere diameter is Dw, then inner ring contact point diameter: Dc=Dp-Dw*Cos α
Equally, the inner ring revolution, steel ball rolls, and the outer ring is static.
Because inner ring contact point revolution tangential velocity is 2 times of steel ball center steering tangential velocity, therefore, inner ring contact point revolution tangential distance is 2 times of steel ball center steering tangential distance.
We make the inner ring revolution, and steel ball rolls, and the steel ball center steering drives retainer revolution 1 circle.
Steel ball center steering tangential distance is a centre of sphere footpath girth: π * Dp
Inner ring contact point revolution tangential distance is above 2 times: 2* π * Dp
Above distance is equivalent to the inner ring revolution number of turns: 2* π * Dp/ π * Dc=2Dp/Dc=2+ (2Dp-2Dc)/Dc
Therefore, our rotary inner ring makes retainer revolution 1 circle, and inner ring should turn round 2+ (2Dp-2Dc)/Dc circle, that is to say: inner ring changes (2Dp-2Dc)/Dc circle after turning over 2 circles again, and retainer just in time turns round 1 circle.
Inner ring changes (2Dp-2Dc)/Dc circle correspondence again and turns over angle and be: B=360* (2Dp-2Dc)/Dc degree.
B=360* (2Dp-2Dc)/Dc degree then
=720*(Dp/Dc-1)
=720*Dw*Cos α/(Dp-Dw*Cos α) spends (2)
Make index dial according to different contact angle α correspondences with upper angle.
Rotary inner ring makes retainer revolution 1 circle, directly reads bearing contact angle α by index dial.
Two, bearing protrusion amount detects
The detection of bearing protrusion amount of the present invention need one with the identical check gauge of detected bearing physical dimension, Precision Machining is passed through on two planes, represents the bearing enclose plane concordant.
Earlier check gauge is placed on the measured bearing position before measuring, with 9 pairs zero of pen type transducer probe assemblies.Take off check gauge then, change detected bearing.The distance of the measured bearing Internal and external cycle end face under respective loads of pen type transducer probe assembly 9 readings representative at this moment, i.e. bearing protrusion amount.
What should be understood that is: the foregoing description is just to explanation of the present invention, rather than limitation of the present invention, and any innovation and creation that do not exceed in the connotation scope of the present invention all fall within protection scope of the present invention.
