Abstract
The invention relates to a friction tester of an escalator main drive shaft. The friction tester comprises a sensor, a lever mechanism, and a support; the escalator main drive shaft is fixedly arranged on the support; the lever mechanism is connected with the escalator main drive shaft, the sensor is arranged on the lever mechanism; a force application device is arranged above the escalator main drive shaft, and is used for continuous load application on the escalator main drive shaft so as to forcibly drive the immobilized escalator main drive shaft to rotate; and the sensor is used for displaying the largest static friction force of the escalator main drive shaft. Compared with existing technology, the friction tester is high in load and accuracy, and is convenient for using.
Description
Technical field
The present invention relates to a kind of friction testing instrument, especially relate to a kind of staircase drive shaft friction testing instrument.
Background technology
Driving device of escalator comprises motor, speed reduction unit, main drive shaft, central siphon, drive sprocket, ladder sprocket wheel, bearing seat etc., wherein the two ends of main drive shaft are separately fixed on two bearing seats, bearing seat is arranged on again on the truss of escalator, central siphon is set in outside main drive shaft, and be equipped with bearing arrangement between central siphon and main drive shaft, central siphon can be rotated around main drive shaft, the axial two ends of central siphon are formed with central siphon flange, two ladder sprocket wheels are fixed with two central siphon flanges respectively, drive sprocket and a ladder sprocket wheel fixed installation.When work, motor and speed reduction unit pass to drive sprocket by chain by power, and drive sprocket connects ladder sprocket wheel and rotates, and ladder sprocket wheel and central siphon are fixed, and also drive the component movement such as step in the time that main drive shaft rotates by step chain.This driving product of having continued to use decades not only heaviness and also cost high, the effect that drive shaft especially is wherein born is great, easy to wear, therefore needs it to carry out frictional dissipation performance test.Existing drive shaft friction test instrument exists the problems such as speed adjustable range is little, load is little, precision is low, and data-handling capacity is poor.
Summary of the invention
Object of the present invention is exactly to provide a kind of load large, easy to use in order to overcome the defect that above-mentioned prior art exists, the staircase drive shaft friction testing instrument that precision is high.
Object of the present invention can be achieved through the following technical solutions: a kind of staircase drive shaft friction testing instrument, it is characterized in that, comprise sensor, leverage, support, main shaft is fixed on support, and described leverage connects main shaft, and described sensor setting is on leverage, main shaft top is provided with augmentor, constantly to main shaft imposed load, make by force main shaft from being fixed to rotation by augmentor, and sensor show the maximum static friction force of main shaft.
Described support comprises base, portal, main shaft holder, and described portal is arranged on base, and described main shaft holder is arranged in portal, and described main shaft is fixed on main shaft holder.
Described main shaft holder is provided with two, and described augmentor is arranged on portal.
Compared with prior art, first the present invention is placed on support by main shaft and fixes, then by leverage and main shaft assembling, make by force main shaft fix by the augmentor of main shaft top and make its rotation, show by the data of observing on sensor the maximum static friction force that records main shaft with this, simple in structure, maximal friction that can automatic detection main shaft.
