TH27747C3 - Synthetic rope - Google Patents

Abstract

DC60 (06/11/52) A synthetic rope with aramid strands in parallel. Together in a tight layer of strands And a sleeve between threads with the surface of the casing being Adjusted to suit the external layout of the strand attached layers. By connecting the inner layer And the outer layer of the positive strand Higher torsional resistance strength will be made. Achieve success Like the rope structure of the stranded rope Which is less susceptible to twisting. In addition, a flexible inter-strand sheath is provided for Prevents the strands from being abrasive And abrasion in the transmission of force and torque within the rope above Large area With reference to the traction rope driven by the rope pulley. Where the strand covering (12) was laid with the opposite strand on the cores parallel to each other (9) and with the sheath. Between strands (13), between layers of opposing strands (16,12) to improve transmission within In the force with the casing It is proposed to adjust the surface of the casing sleeve. The cover between the strands (13) fits the outer contour of the adjacent strands (8,12) in this method due to the friction and shape of the sheath. The inter-helical sheath (13) passes the force and torque of the covering (12) to the core (9), and this ensures a uniformity across the entire surface. Outside of the casing By connecting the inner layer and The outer layer of the strand, the higher torsional strength of the rope (1) will be achieved.

Claims (6)

1. a rope to be driven by a pulley, a puller, or a drum. Which will consist of a central joint layer Same inside And outside at least one layer of strand of fibers Synthetic supporting loads (2,4,7,10) arranged together and between the inner strand layer (5,8) and the outer strand layer (12) the sheath between the strands (13). Which has a tubular shape which will surround Around the inner layer of the strand (5,8) has been characterized as the sheath. Between the strands (13) there is a sheath surface, from which Adaptation to the external scheme of the strand adjacent layers (8,12) 2. Rope according to claim 1, which has been characterized That's specifically the coefficient of friction Between the strands (4,7,10) and the between the strands (13) is greater than 0.15. 3. Rope according to claim 1, which has been characterized That's only the total expansion of the casing. The cover between the strands (13) is greater than the maximum movement of the strand (4,7,10) in relation to the other strand. 4. Rope according to claim 1, which has been characterized That is specific to what the casing surface is given. Furrowing 5. Rope according to claim 1, which has been characterized Specifically, the groove (20) will have a spiral shape. Section direction That is threaded (11) on the outer surface of the casing, which is located Opposite to the direction of the thread (3) of the groove (19) on the inner surface of the casing. 6. Rope according to claim 1, which has been characterized Specifically, the thickness s of the casing (20) at the thinnest point The value of the casing is 0.1 mm.
