Abstract

The utility model relates to torque control turntable bearing starting torque measuring equipment, and belongs to the technical field of bearing measurement. Landing legs are fixedly connected with a workbench, a servo motor drives a speed reducer and a transmission shaft to perform rotary motion, and then drives a torque sensor to enable a rotating disk to rotate through a shaft, the arm of force can be adjusted leftwards and rightwards relative to the rotating disk, a transmission column is connected to the arm of force, the transmission column is inserted into a bearing outer bushing hole along with changes of the center distance of the bearing outer bushing hole in a radial direction, and drives the casing to rotate, an inner bushing is fixed on the workbench through a locating pin, the outer bushing rotates relative to the inner bushing, and the torque sensor transmits a corresponding torque signal. The torque control turntable bearing starting torque measuring equipment has the beneficial effects that torque control is directly performed through a driving motor, the movement trend of the bearing is monitored constantly, driving torque gradually approaches starting torque of the bearing, the starting toque of the turntable bearing can be measured accurately, and the whole measurement process is automatic.

Description

A kind of turntable bearing staring torque measurement mechanism of torque control

technical fielda turntable bearing staring torque measurement mechanism for torque control, belongs to bearing measuring technical field.

background technologythe staring torque of turntable bearing is a critical index of product, and traditional metering system is the moment of torsion maximal value of measuring in bearing start-up course, the staring torque using this value as bearing.The moment of inertia of turntable bearing is generally all larger, and the angular acceleration that starts moment is larger, and the deviation of moment of torsion maximal value and staring torque is just larger, makes measurement result produce larger error.

utility model contentin view of the defect that prior art exists, the purpose of this utility model is to provide a kind of measuring accuracy that improves turntable bearing staring torque, reflects truely and accurately the turntable bearing staring torque measurement mechanism of the technical indicator of product.

For achieving the above object, the technical solution that the utility model adopts is: a kind of turntable bearing staring torque measurement mechanism of torque control, supporting leg is fixedly connected with worktable, servomotor drives speed reduction unit and transmission shaft to rotatablely move, drive again torque sensor, make rotating disc rotation by axle, the arm of force is adjusted rotating disc left and right relatively, take off post and be connected on the arm of force, take off post and insert in bearing outside hole with the radial variations of bearing outside hole centre distance, and drive overcoat to rotate, inner sleeve is fixed on worktable by register pin, overcoat rotates relative to inner sleeve, the corresponding torque signals of torque sensor transmission.

A kind of turntable bearing staring torque measurement mechanism of torque control, its beneficial effect is: by drive motor is directly carried out to torque control, the constantly movement tendency of monitoring bearing, make driving torque approach gradually the staring torque of bearing, can accurately measure the staring torque of turntable bearing, all measuring process robotizations.
