It can be mainly used in railway freight car bearing assembling field.
Description
Technical field
The invention belongs to railway truck bearing mounting technology field.
Background technology
1. before this, the railway truck bearing play is to adopt upset play instrument to detect, because the existence of inside and outside raceway phosphate coating causes bearing real work play uncontrollable, causes the bearing dynamic mass to descend simultaneously, the work temperature rise.
2. along with the speed raising again and again of transportation by railroad, the dynamic mass of railway bearing is just apparent more important, and the dynamic mass of China railways freight car bearing never has the means detection.
3. railway truck bearing adopts manual setting and inspection always, and assurance ability is low.
Summary of the invention
Purpose of the present invention just provides that a kind of quantitatively to fill fat even, and real-time online detects moment of torsion, forms automatic greasing, presses cover, surveys moment of torsion, the production line of even fat, enhances productivity torque measuring method that reduces production costs and device.
Technical solution of the present invention is to be made up of digital signal processing circuit and rotary encoder cylinder 36, torque sensor 37; , support platform 38, cylinder 39, claw 40, claw 41, cylinder 42, reverse axle 43, cylinder 44, motor 45, stationary installation 46, turning axle 47, claw 48, claw 49, pusher 50, carrier bar 51, driven shaft 52, cylinder 53 and form.
Torquer has two cylinders, reverses axle, torque sensor, digital signal processing circuit and rotary encoder and forms.
Detect the moment of torsion principle: cylinder piston will reverse axle shift onto with brearing bore apart from end face 15mm place, fixing on axle: the secondary coil of energy toroidal transformer, signal toroidal transformer primary coil and axle are gone up printed circuit board (PCB), comprise rectification stabilized power source, instrument amplifying circuit, V/F translation circuit and signal output apparatus on the circuit board.The electric signal turned round of axle is presented at signal on the display screen by torque sensor and digital signal processing circuit and rotary encoder.The energy input and the signal output of native system are to be born by the special ring-shaped transformer of two groups of band gaps, have therefore realized the contactless energy and signal transfer function.
Detect the torque operation step: pusher 18 is shifted bearing onto the torquer below.Steam-operating workbench 44 spring bearings, cylinder piston 36 descends, to reverse axle 43 shift onto with brearing bore apart from end face 15mm place, claw 40,41 clamps the bearing seal closure by cylinder 39,42, reverse axle twisting, the electric signal that axle is turned round is presented at signal on the display screen 3 by torque sensor 37 and digital signal processing circuit and rotary encoder.Cylinder piston will reverse axle and return original position, and pusher 18 promotes this bearing to equal fat device place.
The beneficial effect that the present invention reached is: both can measure static moment of torsion, and also can measure rotating torques; The accuracy of detection height, good stability; Strong interference immunity; But continuous coverage torque; Sensor output high level frequency signal can directly send Computer Processing.
Description of drawings
The present invention is further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is a microprocessor side view of the present invention.
Fig. 2 is torsion-testing figure of the present invention.
