Abstract
The utility model relates to a staircase driving main shaft friction tester. The staircase driving main shaft friction tester comprises a sensor, a lever mechanism and a bracket, wherein a main shaft is fixed on the bracket; the lever mechanism is connected with the main shaft; the sensor is arranged on the lever mechanism; a forcing device is arranged above the main shaft; a load is applied to the main shaft continuously through the forcing device so that the main shaft is forced to be rotated from being fixed; and the sensor displays maximum static friction force of the main shaft. Compared with the prior art, the staircase driving main shaft friction tester has the advantages of being large in load, convenient to use, high in precision and the like.
Description
Technical field
The utility model relates to a kind of friction testing instrument, especially relates 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 installed in again on the truss of escalator, central siphon is set in outside the main drive shaft, and be equipped with bearing arrangement between central siphon and the main drive shaft, make central siphon to rotate around main drive shaft, the axial two ends of central siphon are formed with the central siphon flange, two ladder sprocket wheels are fixed with two central siphon flanges respectively, drive sprocket and a ladder sprocket wheel fixed installation.During work, motor and speed reduction unit are given drive sprocket by chain with transmission of power, and drive sprocket connects ladder sprocket wheel and rotates, and ladder sprocket wheel and central siphon are fixed, and also drive component movement such as step when main drive shaft rotates by step chain.This driving product of having continued to use decades is heaviness but also cost height not only, and the effect that drive shaft is especially wherein born is great, and is easy to wear, therefore need carry out the frictional dissipation performance test to it.Existing drive shaft friction test instrument exists that speed adjustable range is little, load is little, precision is low, problems such as data-handling capacity difference.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of load big, easy to use for the defective that overcomes above-mentioned prior art existence, the staircase drive shaft friction testing instrument that precision is high.
The purpose of this utility model 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 the support, and described leverage connects main shaft, and described sensor is arranged on the leverage, the main shaft top is provided with augmentor, constantly to the main shaft imposed load, make main shaft from being fixed to rotation by augmentor by force, and sensor show the maximum static friction force of main shaft.
Described support comprises base, portal, the main shaft holder, and described portal is arranged on the base, and described main shaft holder is arranged in the portal, and described main shaft is fixed on the main shaft holder.
Described main shaft holder is provided with two, and described augmentor is arranged on the portal.
Compared with prior art, the utility model at first is placed on main shaft on the support and fixes, then with leverage and main shaft assembling, by the augmentor above the main shaft main shaft is fixed and made its rotation, record the maximum static friction force of main shaft by the data presentation of observing on the sensor with this, simple in structure, can survey the maximal friction of main shaft automatically.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
