Specific embodiment
Specific embodiment is provided below in conjunction with the accompanying drawings.
The specific embodiment of the present invention is to make the bent ditch Friction Moment of Ball Bearings measurement dress that total length is 850mm
Put, bent ditch Friction Moment of Ball Bearings is measured with it, specifically as shown in Figure 1, Figure 2, Figure 3 and Figure 4.Motor reducer 12 is defeated
After going out power, further slow down through little gear 12, reach the relatively slow-speed of revolution needed for measurement of friction torque；Base 2 is fixed on frame 1
On, there is the spherical nest 15 equal with the steel ball quantity of measured bearing 10 on base 2 on a circumference, turn part 4 and fixed with scroll chuck
Together, and turning part 4 there is same-amplitude and pitch with the outer ring of measured bearing 10 with being machined with 2 corresponding circumference of base
Serpentine circular curve groove 14, loading steel ball 3 coordinates with turning part 4 in base 2, and gear wheel 5 drives what scroll chuck 6 rotated
Meanwhile the in the vertical direction lower swing of scroll chuck 6, measured bearing 10 is adjusted by the phase adjusted nut 13 on loading disc 8
Phase so that the phase swung up and down of scroll chuck 6 is swung up and down with measured bearing 10 on the contrary, being surveyed with offsetting to swing to power
The influence of accuracy of measurement；The axle of the inner ring of measured bearing 10 and loading disc 8 is interference fit, and the outer ring of measured bearing 10 is by scroll chuck 6
Claw step up and with the uniform rotation of scroll chuck 6, due to the presence of moment of friction, the inner ring of measured bearing 10 also have with
The trend of outer ring rotating, now pulling force sensor 7 give measured bearing 10 inner ring, one pulling force by loading disc 8, make measured bearing
10 inner rings are remained static, and the torque that pulling force sensor 7 acts on inner ring can be tried to achieve by the pulling force for implementing to measure with the arm of force
Moment of friction.Axial load can be adjusted by applying different counterweights on loading disc 8.
The present invention can make different structure size according to the structure of tested bent ditch ball bearing and the size of bearing capacity
Measurement of friction torque device, can also by provided with curved grooves 14 turn part 4 change into be tested bent ditch ball bearing curve shape it is complete
Complete similar another bent ditch ball bearing carries out up and down motion compensation.These all form the other embodiment of the present invention.
