Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The schematic diagram of steel band static friction coefficient testing machine of the present utility model as shown in Figure 1, comprise base 6, on described base 6, order is provided with traction cylinder 1, the first angle sheave 2 freely rotated, the second angle sheave 3 freely rotated, fixed traction sheave 4 and balancing weight 5, one end of detected steel band 7 is fixedly connected with the push rod of described traction cylinder 1, described detected steel band 7 is successively through described first angle sheave 2, second angle sheave 3 is fixedly connected with described balancing weight 5 with traction sheave 4, on the described detected steel band 7 of described traction cylinder 1 push rod, tractive force pick-up unit is installed.
In the present embodiment, described tractive force pick-up unit comprises pulling force sensor 8, A/D converter and digital indicator 9, and the output terminal of described pulling force sensor 1 is connected with described digital indicator 9 by described A/D converter.The pulling force data that pulling force sensor 8 detects converts numerical information to by A/D converter, is shown by described digital indicator 9.
During use, start traction cylinder 1 and pull detected steel band 7.Read detected steel band and be in the value of thrust under critical glide state along traction sheave, according to the friction factor relational expression of flexible body to rigid body, be Euler's formula, calculate the static friction coefficient of detected steel band.
Testing machine of the present utility model can real simulation elevator traction steel band and traction sheave real surface coefficient of static friction in high speed lifting process, for traction steel band on stream its Roughness Surface on Control provide reliable data basis.And structure is simple, easy to use.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
