technical field [0001] The invention relates to a non-joint steel wire rope and pad sliding friction pair device, especially suitable for a non-joint steel wire rope and pad continuously variable sliding friction testing machine. Background technique [0002] The sliding friction pair device of the steel wire rope and the pad on the pad and wire rope friction tester determines the feasibility of using the testing machine to simulate the slipping condition of the mine friction hoist and the reliability of the results of the research on the tribological performance of the pad. The steel wire rope and the pad sliding friction pair of the existing liner and wire rope friction testing machine are mostly based on the principle of the plane method, that is, the two liners clamp the steel wire rope under the action of loading force and stand still, and the two ends of the steel wire rope are connected to the hydraulic cylinder.

Problems solved by technology

The steel wire rope and the pad sliding friction pair of the existing liner and wire rope friction testing machine are mostly based on the principle of the plane method, that is, the two liners clamp the steel wire rope under the action of loading force and stand still, and the two ends of the steel wire rope are connected to the hydraulic cylinder. Or the steel wire rope is wound on the drum, and the steel wire rope is twitched to cause sliding friction with the liner, which is not in line with the actual sliding friction conditions between the arc-shaped lining block on the mine friction hoist and the steel wire rope, and is limited by the rope capacity of the drum. , Hydraulic cylinder piston rod movement speed is low and other limitations, this kind of steel wire rope and liner sliding friction pair has the disadvantages of short sliding distance and low sliding speed

And the patent (CN201110436607.0) discloses a mine friction hoist liner sliding friction tester that uses a plurality of liners embedded in the wheel and steel wire ropes that are stretched at both ends on the half circle of the wheel to form a steel wire rope. The friction pair with the liner, the steel wire rope presses the liner and stands still, and the liner rotates with the wheel so that sliding friction occurs between the liner and the steel wire rope; although the friction contact form of the friction pair is similar to the actual situation and makes the structure of the friction testing machine simple, However, since the liner rotates with the wheel, sometimes it is in contact with the steel wire rope, and sometimes it is separated from it, and when the liner is in different positions within a rotation cycle, the specific pressure it receives is variable and uncertain, so it is not conducive to the correct and direct study of the liner.
