Description
Technical field
The present invention relates to a kind of staircase drive shaft dependence test device, especially relate to a kind of staircase drive shaft tensioner
Set force moment testing device.
Background technology
Existing driving device of escalator includes motor, reduction box, main drive shaft, drive sprocket, first driven
Sprocket wheel and the second driven sprocket, drive sprocket, the first driven sprocket and the second driven sprocket are both connected to main drive shaft
On.Motor and reduction box impart power to drive sprocket by chain, and drive sprocket drives main drive shaft to rotate,
Thus driving two driven sprockets to rotate, driven sprocket is then moved by parts such as chain-driving steps.Main drive shaft
In driving device of escalator, gas has arrived important function, and wherein the stiction size of the expansion sleeve of main drive shaft is straight
Connecing the performance that have impact on main drive shaft, the most how the stiction to expansion sleeve carries out test becomes and is instantly badly in need of solving
Problem certainly.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and a kind of certainty of measurement is provided
High, easy to operate, realize low cost, staircase drive shaft expansion sleeve force moment testing device that reliability is high.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of staircase drive shaft expansion sleeve force moment testing device, it is characterised in that include fixed mount, screw rod, friction
Force measuring instrument, gripping sleeve, drive link and force bolt, described screw rod is fixed on fixed mount, described friction
Force measuring instrument is connected with gripping sleeve, and described gripping sleeve is connected with screw rod by drive link, described expansion sleeve to be measured
Being located in gripping sleeve, described force bolt is connected with screw rod；
Screw motion, screw motion drive is driven to step up set and step up, make the tensioner of motion by tightening force bolt
Set stops, and friction measurement instrument shows the maximum static friction force that this expansion sleeve rotates.
Also include the base plate for placing fixed mount and gripping sleeve.
Compared with prior art, the invention have the advantages that
1, certainty of measurement is high, is measured by friction measurement instrument, is surveyed by naked eyes relative in prior art
Examination, its precision improves a lot；
2, easy to operate, it is only necessary to by tightening force bolt, test can be completed；
3, realize low cost, existing equipment was entered transformation and can realize this function；
4, reliability is high, and the parts of employing are ripe parts.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
