Pre-tightening load is applied to the end face of the inner ring of the bearing to be measured, and loading on the roller bearing is conducted in a way of simulating the bearing means of an outer ring in actual use. The vibration of the roller bearing is measured, and the measuring position of the sensor is changed at the same time, so that the measuring area is adapted to the vibration amplitude area. The accuracy for determining the vibration level of the roller bearing is improved.
Description
Technical field
The present invention relates to a kind of roller bearing vibration measurement device.
Background technology
At present, roller bearing vibration measurements is qualified, but in installation use procedure, its vibration, noise but not necessarily can reach the request for utilization of client.Show by analysis, at present, when measuring the vibration of roller bearing, bearing inner race is arranged in axle, and with central axis, the axial pretightening load that inner ring is in addition certain, outer ring applies corresponding radial load, and radial load direction vertically downward.But in real work, the radial load that bearing outer ring bears is straight up.Therefore the load that the load used in measuring uses centre bearer to bear with reality is not identical.Further investigation can find, current roller bearing measuring method does not consider the impact of deadweight on bear vibration of Bearing inner roller.This will inevitably produce certain measuring error.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of roller bearing vibration measurement device.
Described a kind of roller bearing vibration measurement device, it is characterized in that comprising: sensor, axle, flexible cushion block and slide block, described axle is for installing measured bearing, the gauge head of described sensor contacts with the top of described measured bearing, described slide block comprises the first slide block and the second slide block, described flexible cushion block comprises the first flexible cushion block and the second flexible cushion block, described first flexible cushion block is arranged on described first slide block, described second flexible cushion block is arranged on described second slide block, and the top of described first flexible cushion block and described second flexible cushion block contacts with the outside surface of measured bearing, and radial load is applied to measured bearing.
Described roller bearing vibration measurement device, is characterized in that being formed centrally an angle in contact point on measured bearing outside surface of described first flexible cushion block, described second flexible cushion block and axle.
Described roller bearing vibration measurement device, is characterized in that the first flexible cushion block, the contact point of described second flexible cushion block on measured bearing outside surface be axis of symmetry with the gauge head of described sensor at the line of centres of the contact point concentric shafts at measured bearing top.
Described roller bearing vibration measurement device, it is characterized in that described roller bearing vibration measurement device also comprises locking device, described locking device is connected with described axle, for the inner ring end face of fixing measured bearing, and applies prefastening load.
The present invention is by applying prefastening load to the inner ring end face of measured bearing, and adopt the bearing mode of the outer ring under the actual service condition of simulation to load roller bearing, measure the vibration of roller bearing, change the measuring position of sensor simultaneously, measured zone is made more to suit in vibration amplitude region, effectively can reduce because load mode is improper and the improper measuring error brought of measuring method, improve the accuracy rate judging roller bearing vibration class.
