Embodiment
Referring to attached drawing 1 ~ 3, a kind of matched cone roller bearing torque test fixture disclosed in the utility model, including mandrel
1 and external bushing 2, described 1 one end of mandrel be plugged in external bushing 2, be set with successively vertically between mandrel 1 and external bushing 2
Two row tapered roller bearings 3, the outer ring of two row tapered roller bearings 3 are arranged at intervals, and external bushing 2 is equipped with to left side taper roller
Bearing 3a outer rings left end contradicts spacing fixation rib 21, is equipped with and right side taper roll bearing 3b outer rings right end in external bushing 2
The outer ring gland 4 contacted, outer ring gland 4 can be axially movable in external bushing 2, and the external bushing 2 is kept off axially away from fixed
The one end on side 21 is installed with end cap 5 through bolt, and end cap 5 is equipped with the threaded hole 51 coaxial with mandrel, the screw thread of the end cap 5
51 screw-internal thread fit of hole has loading nut 6, loads and is axially folded with disc type pressure sensor 7 between nut 6 and outer ring gland 5.
Disc type pressure sensor 7 is the component that can be directly bought on existing market, and the structure of itself is not changing for the invention
Into, therefore no longer repeated for its structure, loading nut is screwed in, loading nut passes sequentially through disc type pressure sensor, outer ring
Gland applies axial compressive force to right side taper roll bearing outer ring, so that reach the simulation of two row tapered roller bearing axial loads,
