Technical fieldThe invention belongs to bearing and make the field, relate to a kind of bearing testers device, concrete a kind of bearing moment of torsion that is applicable to the measurement use of bearing moment of torsion that relates to detects testing machine.
Background technologyThe friction torque of bearing is the numerical value that Theoretical Design obtains, and is difficult to determine its size in production practices always.Along with the gradually raising of bearing accuracy, the gradually refinement of customer requirement has proposed further requirement to bearing friction torque, for the development trend of bearing, is badly in need of developing a kind of bearing torsional moment test and detects machine.This bearing torsional moment test detects machine can be by the measurement check to the bearing moment of torsion, determine the friction torque of bearing self, provide definite data for the client uses, thereby can guarantee that the client is reasonably correctly using bearing products and guaranteeing the q﹠r that bearing products dispatches from the factory under the condition.
Summary of the inventionIn view of the defective that prior art exists, the objective of the invention is to provide a kind of bearing moment of torsion to detect testing machine, change existing bearing frictional torque little, be difficult for the present situation of measurement, definite data are provided, and then improve quality and the reliability of product.
For achieving the above object, technical scheme of the present invention is as follows:
The bearing moment of torsion detects testing machine, comprise a body, the moment of torsion that is arranged on the body transmits testing agency and load maintainer, it is characterized in that: the servomotor that described moment of torsion transmits testing agency connects in order to detect the torque tester of moment of torsion and rotating speed size by shaft coupling elasticity, torque tester connects the static pressure axle by shaft coupling elasticity, the static pressure axle covers the static pressure axle box outward, and measured bearing is installed in the bearing frock, and the bearing frock connects the static pressure axle by flange; The oil cylinder of described load maintainer connects radial loaded mechanism by torque sensor, and radial loaded mechanism imposed load is to the bearing frock, and the size of its imposed load is detected by torque sensor.
Described moment of torsion transmits testing agency and also comprises the torque tester adjusting mechanism, guarantees torque tester and the concentric requirement of static pressure axle in vertical and horizontal direction by adjusting the torque tester adjusting mechanism.
Described bearing frock is comprised of connect with the heart axle and the bearing seat of some different models, to adapt to the torque measurement of different bearing designations and size, guarantees versatility.
Described load maintainer also comprises radial loaded institutional adjustment mechanism, requires the position in order to guarantee that radial loaded mechanism is carried in.
The noise that produces in order to alleviate the testing machine body vibration is installed some beams below the bed body.
The present invention is connected with torductor by shaft coupling by servomotor, torductor drives measured bearing by the static pressure axle at last and rotates by shaft coupling and static pressure axle, has guaranteed the continuity that bearing rotates, guarantee to measure the accuracy of moment of torsion, make its steady transmission; In order to satisfy different bearing designations and the torque measurement of bearing size.Design different bearing frocks.According to the variation of internal-and external diameter, change different connection axle and bearing seat; Actual applying working condition according to bearing loads different radial forces, makes the numerical value that detects moment of torsion more accurate, and the radial force of bearing is applied on the measured bearing by load maintainer by oil cylinder.
In sum, advantage of the present invention is as follows: the present invention is directed to the present situation that bearing friction torque is little, be difficult for measurement, adopt static pressure axle transmitting torque, lower the disturbed amount of measured value; Adopt simultaneously the torductor that precision is high, numerical value collection susceptibility is high to gather numerical value, guarantee the accurate, reliable of measured value; Oil cylinder loads and can guarantee the stable of load, by adjusting the size of oil pressure, satisfies the requirement of different loads size, and loaded load scope maximum can reach 7T; By changing different frocks, the measured bearing inside diameter ranges is 30mm ~ 120mm.
